Description

Method and equipment for configuring logical channel

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a device for configuring a logical channel.

Background

In the fifth generation mobile communication technology (5G) system, a duplicate (duplication) function of the PDCP layer is introduced. The repetition of the PDCP layer generally refers to the repetition of a data packet of a radio bearer into two identical packets (i.e., a repetition packet), and then the two data packets are respectively submitted to two different Radio Link Control (RLC) entities for transmission, and further transmitted to a Medium Access Control (MAC) layer through different logical channels.

In order to ensure the reliability of data transmission, the original data packet and the copied data packet transmitted to the MAC layer cannot be transmitted through the same MAC Protocol Data Unit (PDU), because only through transmission of different MAC PDUs, the transmission of another MAC PDU cannot be affected by the loss of one MAC PDU, which is equivalent to that the reliability is doubled. Therefore, two data packets can be transmitted to different MAC entities through different logical channels, and finally two MAC PDUs are formed for transmission on different carriers.

Currently, the repetition of the PDCP layer is limited to one radio bearer transmitting a packet duplicated in the PDCP layer through two RLC entities and two logical channels. For example, when the repetition function of a radio bearer PDCP layer is activated, data from logical channel 1 can only be transmitted on carrier 1 or carrier 2, and data from logical channel 2 can only be transmitted on carrier 3. At a certain time, after the repeated function of the PDCP layer of the radio bearer is deactivated, only the logical channel 1 is left to be operated, and at this time, in order to increase the transmission capacity, the data in the logical channel 1 can be transmitted on all available carriers. However, when the repetition of the PDCP layer is not limited to two RLC entities and two logical channels, how to use the RLC entity after the deactivation is still a problem to be solved.

Disclosure of Invention

The embodiment of the application provides a method and equipment for configuring a logical channel, which are used for solving the technical problem of how to allocate a carrier corresponding to the logical channel after the logical channel is deactivated.

In a first aspect, a first method for configuring a logical channel is provided, the method including: determining indication information, wherein the indication information is used for indicating that an association relationship is set according to a first mode, the association relationship is a relationship between an activated logical channel and a carrier, the carrier comprises a carrier associated with a deactivated logical channel, the activated logical channel and the deactivated logical channel belong to the same radio bearer, and data packets of the radio bearer are copied into at least three parts and are transmitted through the at least three logical channels respectively; and sending a first signaling to the terminal equipment, wherein the first signaling comprises the indication information.

The method may be performed by a first communication device, for example a network device or a communication device capable of supporting a network device to implement the functions required by the method, or for example a chip capable of being provided in a network device. The network device is for example a base station.

In this embodiment of the present application, a radio bearer transmits duplicated data packets through at least three logical channels, where the data packets are duplicated in a PDCP layer, and the indication information may indicate that an association relationship between an activated logical channel and at least one carrier is set according to a first manner, where the at least one carrier includes a carrier with which a deactivated carrier is associated before deactivation, that is, for a case where the radio bearer transmits the data packets duplicated in the PDCP layer through a plurality of logical channels, if a logical channel is deactivated, then this embodiment of the present application provides a method for allocating a carrier with which the deactivated logical channel is associated among remaining activated logical channels. In addition, if a logical channel is activated, the embodiments of the present application provide a method how to reallocate carriers to the respective activated logical channels.

With reference to the first aspect, in a possible implementation manner of the first aspect, the carrier only includes a carrier with which the deactivated logical channel is associated before deactivation; or, the carriers include all carriers of the terminal device in an activated state, and all carriers of the terminal device in the activated state include carriers associated with the deactivated logical channel before deactivation; or, the carrier includes other activated carriers of the terminal device except for the carrier associated with the activated logical channel, and the other activated carriers of the terminal device except for the carrier associated with the activated logical channel include the carrier associated with the deactivated logical channel before deactivation.

The carriers may only include carriers associated with the deactivated logical channel before deactivation, and only the carriers associated with the deactivated logical channel before deactivation need to be reallocated, and the number of carriers to be allocated is small and the workload is low. Or, the carriers may also include all the carriers in the active state of the terminal device, which is equivalent to reallocating all the carriers in the active state of the terminal device, and all the carriers in the active state of the terminal device may also include carriers that have not been previously associated with any logical channel, so that more carriers may be associated with logical channels, and the transmission quality of the data packet duplicated in the PDCP layer is improved. Alternatively, the carriers may include other activated carriers of the terminal device besides the carrier associated with the activated logical channel, so that more carriers may be associated with the logical channel, and the transmission quality of the data packet duplicated at the PDCP layer is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first manner includes one or any combination of the following: establishing an association relationship between the carrier and the activated logical channel according to the size sequence of the ID of the carrier, wherein the association relationship is established between one carrier of the carrier and one logical channel of the activated logical channel each time; or, establishing an association relationship between the carrier and the activated logical channel according to the order of the quality of the channel of the carrier, wherein the association relationship is established between one carrier of the carrier and one logical channel of the activated logical channel each time; or, establishing association relationship between the carrier and one of the activated logical channels; or, when the number of the activated logical channels is equal to 1, establishing an association relationship between the carrier and the activated logical channels; or, establishing an association relationship between the carriers and the activated logical channels according to the sequence of the corresponding IDs of the deactivated logical channels, wherein all carriers associated with one deactivated logical channel before deactivation establish an association relationship with one activated logical channel; or establishing association relation between each carrier of the carriers and one logic channel of the activated logic channels according to a random mode.

The embodiment of the application provides a plurality of modes. For example, if the channel quality of carriers associated with some logical channels is good, and the channel quality associated with some logical channels is poor, the carriers may not be able to play a role of repeating the PDCP layer. Alternatively, the carrier may be associated with one of the activated logical channels, so that the carrier does not need to be allocated among a plurality of logical channels, which is a simple manner. Or, the carrier associated with a deactivated logical channel before deactivation may be unified with an activated logical channel to establish an association relationship, which is equivalent to performing allocation with the logical channel as granularity, thereby simplifying the allocation process.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first signaling further carries one or more bitmaps, where one bitmap is used to indicate an association relationship between one logical channel and a carrier, and a logical channel corresponding to the one or more bitmaps is the activated logical channel.

The first signaling can directly carry the bitmap corresponding to each logical channel of all or part of the activated logical channels, so the terminal equipment can set the association relationship between the corresponding logical channels and the carriers according to the bitmap carried by the first signaling, and the method is simpler and more direct. For example, the first signaling may carry a bitmap corresponding to each logical channel of all logical channels, and the indication is more definite, or the association relationship between some logical channels and the carrier may not change, so the first signaling only needs to carry the bitmap corresponding to the changed logical channel, which is helpful to reduce signaling overhead and also reduces the processing procedure of the terminal device.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes: and sending a second signaling to the terminal device, wherein the second signaling is used for indicating the deactivation of one or more logic channels of the radio bearer, the second signaling also carries one or more bitmaps, one bitmap is used for indicating the incidence relation between one logic channel and a carrier, the logic channel corresponding to one or more bitmaps is the remaining activated logic channel of the radio bearer, and the remaining activated logic channel is the remaining activated logic channel after the deactivation of one or more logic channels of the radio bearer.

And when the second signaling carries the bitmap, the realization form of the bitmap is similar to that when the first signaling carries the bitmap.

The first signaling may indicate to disassociate the first logical channel from the first carrier, for example, the first carrier has poor channel quality, and the first communication device may indicate to disassociate the first logical channel from the first carrier to improve the transmission quality of the first logical channel. Or, the first signaling may instruct to release the association between the first logical channel and the second carrier, and establish the association between the second carrier and the second logical channel, for example, the channel qualities of the carriers associated with the first logical channel are all good, and the channel qualities of the carriers associated with the second logical channel are all poor, then the first communication apparatus may instruct to move the second carrier from the first logical channel to the second logical channel, so as to improve the channel quality of the carrier associated with the second logical channel, thereby improving the transmission quality of the second logical channel. Alternatively, the first signaling may also indicate that the association relationship between the first logical channel and the third carrier is established, which is equivalent to bringing the carrier that has not been previously associated with the logical channel into the range of establishing the association relationship, for example, the channel quality of the third carrier is better, and thus, after the third carrier is associated with the first logical channel, the transmission quality of the first logical channel is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

1) Terminal equipment, including devices that provide voice and/or data connectivity to a user, may include, for example, handheld devices with wireless connection capability or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an Access Point (AP), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a user equipment (user device), or the like. For example, mobile phones (or so-called "cellular" phones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-included or vehicle-mounted mobile devices, smart wearable devices, and the like may be included. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. Also included are constrained devices, such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, Radio Frequency Identification (RFID), sensors, Global Positioning Systems (GPS), laser scanners, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

2) The network device includes, for example, AN Access Network (AN) device. An access network device, such as a base station (e.g., access point), may refer to a device in an access network that communicates over the air-interface, through one or more cells, with wireless terminal devices. The network device may be configured to interconvert received air frames and Internet Protocol (IP) packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB) in a Long Term Evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-a), or may also include a next generation Node B (gNB) in a fifth generation mobile communication technology (5G) New Radio (NR) system, or may also include a Centralized Unit (CU) and a distributed unit (distributed unit, DU) in a cloud access network (cloud ran) system, which is not limited in the embodiments of the present application.

3) Dual Connectivity (DC), i.e. a terminal device connects two base stations simultaneously. The two base stations to which the terminal device is connected may be base stations in the same radio access technology, for example both base stations in an LTE system or both base stations in an NR system, or the two base stations to which the terminal device is connected may also be base stations in different radio access technologies, for example one base station in an LTE system and the other base station in an NR system.

4) Carrier Aggregation (CA), which can aggregate a plurality of Component Carriers (CCs) together to provide a service for a terminal device, thereby realizing a larger transmission bandwidth and effectively increasing the uplink and downlink transmission rate.

5) The logical channel is associated with the carriers, or the logical channel has an association relationship with the carriers, or may also be referred to as a logical channel having a binding relationship or a binding transmission relationship with the carriers, including but not limited to indicating that data transmitted in the logical channel may be transmitted on some carriers if it is indicated in the configuration of the logical channel that the carriers are allowed to be used, or resources on the carriers may be allocated to the logical channel, which may be referred to as a logical channel being associated with the carriers. Further, data transmitted in a logical channel is not transmitted on a carrier other than the carrier associated with the logical channel. The logical channel corresponding to the packet duplicated at the PDCP layer may have an association relationship with the carrier. In some scenarios, if no carrier association relationship is configured, it is indicated that data transmitted in the logical channel may be transmitted on any carrier.

For example, a parameter, for example, referred to as parameter a, may be configured for the logical channel, and a value of the parameter a indicates different carriers, which indicates that data transmitted in the logical channel can only be transmitted on the carrier specified by the parameter a. For example, parameter a is configured for logical channel 1, and indicates carriers 1 and 2, which indicates that data in the logical channel can only be transmitted on parameter carriers 1 and 2. As described above, the logical channel 1 and the carrier 2 may be said to have an association relationship, or may be said to have a binding relationship or a mapping relationship.

6) The duplication of a Packet Data Convergence Protocol (PDCP) layer means that a PDCP entity duplicates a packet into multiple copies and delivers the multiple copies to different RLC entities, and then transmits the multiple copies from the RLC layer to the MAC layer through a logical channel. The activated logical channel refers to a logical channel used when the repetition of the PDCP layer is activated and/or a logical channel used when the repetition of the PDCP layer is deactivated. The deactivated logical channel refers to a logical channel that is not used when the repetition of the PDCP layer is activated and/or a logical channel that is not used when the repetition of the PDCP layer is deactivated.

7) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first logical channel and the second logical channel are only for distinguishing different logical channels, and do not indicate a difference in priority, importance, or the like between the two logical channels.

Having described some concepts related to embodiments of the present application, the following description will be given of features related to embodiments of the present application.

The duplication of the PDCP layer generally means that a data packet of a radio bearer is copied into a plurality of identical packets (i.e., duplicate packets) at the PDCP layer, and then the two data packets are respectively delivered to a plurality of different RLC entities for transmission, and further transmitted to the MAC layer through different logical channels. Wherein the logical channel is a channel between the RLC layer to the MAC layer. It should be noted that the retransmission is generally referred to as retransmission (retransmission), but the repeated transmission in the embodiment of the present application is not retransmission. The retransmission refers to retransmission after the same data packet fails to be transmitted, or continuous multiple transmission of the same data packet, and the repeat transmission refers to copying one data packet into two data packets, and respectively putting the two data packets onto two logical channels for transmission, where "repeat" may also be understood as "copy".

In order to ensure the reliability of data transmission, the original packet and the repeated packet transmitted to the MAC layer cannot be transmitted through the same MAC PDU, because only through transmission of different MAC PDUs, the transmission of another PDU cannot be affected by the loss of one PDU, which is equivalent to the improvement of one time of reliability.

In the following, how the transmission function of the PDCP layer is implemented is described separately for the DC scenario and the CA scenario.

Referring to fig. 1, a network architecture involved in implementing an iterative procedure of a PDCP layer in a DC scenario is illustrated. For the base station, the DC scenario involves a main base station and a secondary base station, and the network architecture of the main base station and the secondary base station for one radio bearer is as shown in fig. 1, and the network architecture of the terminal device for the radio bearer includes the network architecture of the main base station and the network architecture of the secondary base station shown in fig. 1, that is, the terminal device includes one PDCP entity, two RLC entities and two MAC entities for the radio bearer. Security (security), replication (duplication), slicing (segment), automatic repeat-request (ARQ), multiplexing (multiplexing), hybrid automatic repeat-request (HARQ), robust header compression (ROHC), and the like in fig. 1 are functions representing a PDCP entity, an RLC entity, or a MAC entity. Here, the PDCP entity and the PDCP layer can be understood as the same concept, and similarly, the RLC entity and the RLC layer can be understood as the same concept, and the MAC entity and the MAC layer can be understood as the same concept. The circles in fig. 1 represent interfaces and/or channels between different layers. The interface is called an inter-layer interface, such as a Service Access Point (SAP), and the channel may be a logical channel, which is similar hereinafter and is not described again. It should be noted that fig. 1 is only an exemplary architecture, and the components in the figure are not essential components of the present embodiment. Such as the security module, may be omitted as appropriate.

In a DC scenario, a terminal device connects two base stations, i.e. a primary base station and a secondary base station, and if a repetition function of a PDCP layer is configured for a certain radio bearer, two duplicated data packets in the PDCP layer are transmitted to two different RLC entities and transmitted to different MAC entities through different logical channels, and finally two MAC PDUs are formed for transmission on different carriers. The procedure is the same for both the base station and the terminal device, except that for the base station, the PDCP layer in the primary base station transmits the two duplicated data packets to two different RLC entities, which are respectively located in the primary base station and the secondary base station, and then the RCL entity in the primary base station transmits the received data packet to the MAC entity in the primary base station, and the RCL entity in the secondary base station transmits the received data packet to the MAC entity in the secondary base station, which transmit the data packets via respective carriers. And for the terminal device, two RCL entities and two MAC entities are located in the terminal device, and other processes are the same.

Please refer to fig. 2, which is a network architecture involved in implementing the duplicate function of the PDCP layer in the CA scenario. In the CA scenario, the terminal device is connected to a base station, and the network architecture of the base station and the terminal device for one radio bearer is as shown in fig. 2, that is, the base station and the terminal device for the radio bearer each include one PDCP entity, two RLC entities and two MAC entities. Security, copy, slicing, ARQ, multiplexing, HARQ, and ROHC in fig. 2 are functions representing the PDCP entity, the RLC entity, or the MAC entity.

In a CA scenario, a terminal device is connected to a base station, and the same base station has more than one carrier serving the terminal device. Assuming that a certain radio bearer is configured with the duplicate function of the PDCP layer, two data packets duplicated in the PDCP layer are transmitted to two different RLC entities, and the two RLC entities transmit to the same MAC entity through different logical channels. At this time, since two data packets are transmitted to the same MAC entity, the MAC entity may put the two data packets into one MAC PDU for transmission, so that in order to enable the two data packets to be transmitted through the two MAC PDUs respectively, a parameter, for example, called parameter a, may be configured for the logical channel, and different carriers are indicated by a value of the parameter a, thereby ensuring that the two data packets can finally form two MAC PDUs for transmission on different carriers.

For example, if a parameter a is configured for a logical channel, it indicates that data in the RLC entity corresponding to the logical channel can only be transmitted on the carrier indicated by the parameter a. Therefore, if the parameter a configured for the two logical channels that are duplicated with each other indicates different carriers, two data packets that are duplicated with each other will be finally transmitted on the different carriers, so as to ensure reliability.

In the communication system, the repeating function of the PDCP layer may be configured for the radio bearer, and the repeating function of the PDCP layer configured for the radio bearer may be deactivated. In the CA scenario, after the repeating function of the PDCP layer configured for a radio bearer is deactivated (or referred to as that the repetition of the PDCP layer is deactivated), the association relationship between the logical channel and the carrier in the radio bearer is no longer applicable. Currently, the repetition of the PDCP layer is limited to one radio bearer transmitting the data packet duplicated in the PDCP layer through two logical channels (also known as the repetition transmission of two legs (leg)), and referring to fig. 3, assuming that the repetition function of the PDCP layer is activated (or called, the repetition of the PDCP layer is activated), the data from the logical channel 1 can be transmitted only on the carrier 1 or the carrier 2, and the data from the logical channel 2 can be transmitted only on the carrier 3. At a certain time, the repeated function of the PDCP layer is deactivated, and only the logical channel 1 remains to be operated, at this time, in order to improve the transmission capacity, the carrier binding relationship configured for the logical channel 1 is no longer applicable, that is, the logical channel 1 is allowed to use all available (activated) carriers of the terminal device. As can be seen from fig. 3, the carrier 4 is a carrier that has not been associated with any logical channel before, and if the logical channel 1 is allowed to use all the activated carriers of the terminal device, then the logical channel 1 can use the carrier 4 if the carrier 4 is activated. The logical channel described herein uses a carrier, which means that data transmitted in the logical channel can be transmitted on the carrier.

The communication system may subsequently introduce duplication of the PDCP layer of multiple logical channels, i.e. one radio bearer may transmit data packets duplicated at the PDCP layer through multiple logical channels, for example, may transmit data packets duplicated at the PDCP layer through three logical channels. In this case, if there is a logical channel deactivated under the radio bearer, and there may be a plurality of remaining activated logical channels, how to allocate the carrier corresponding to the logical channel among the remaining activated logical channels becomes an urgent problem to be solved.

For example, a 5G system may perform the PDCP layer repetition through three logical channels, and referring to fig. 4, it is assumed that a certain radio bearer configures three logical channels to transmit a data packet (also referred to as three-leg repetition transmission) duplicated in the PDCP layer, and the PDCP layer duplicates the data packet in three parts and transmits the data packet in logical channel 1, logical channel 2, and logical channel 3, respectively, where data of logical channel 1 may be transmitted on carrier 1, data of logical channel 2 may be transmitted on carrier 2, data of logical channel 3 may be transmitted on carriers 3 to 5, and carrier 6 is a carrier that is not associated with any logical channel. At a certain time, the logical channel 3 is deactivated, so that the carriers 3 to 5 can continue to be used for improving the transmission capacity, and the activated logical channels include the logical channel 1 and the logical channel 2, and the terminal device cannot determine which logical channel the carriers 3 to 5 should establish an association relationship with.

In view of this, the technical solutions of the embodiments of the present application are provided. In this embodiment of the present application, a radio bearer transmits a data packet duplicated in a PDCP layer through at least three logical channels, and the indication information may indicate that an association relationship between an activated logical channel and at least one carrier is set according to a first manner, where the at least one carrier includes a carrier associated with a deactivated carrier before deactivation, that is, for a case where the radio bearer transmits the data packet duplicated in the PDCP layer through a plurality of logical channels, if a logical channel is deactivated, this embodiment of the present application provides a method for allocating a carrier associated with the deactivated logical channel among remaining activated logical channels. Or, when the repetition state of the PDCP layer changes, the embodiment of the present application provides a scheme for adjusting an association relationship between a logical channel and a carrier.

In the following description, the method is applied to the network architecture shown in fig. 5 or fig. 6 as an example. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a network device and the second communication apparatus is a terminal device as an example. If the present embodiment is applied to the network architecture shown in fig. 5, therefore, the network device described below may be a network device in the network architecture shown in fig. 5, and the terminal device described below may be a terminal device in the network architecture shown in fig. 5. Alternatively, if the present embodiment is applied to the network architecture shown in fig. 6, therefore, the network device described below may be the first network device or the second network device in the network architecture shown in fig. 6, and the terminal device described below may be the terminal device in the network architecture shown in fig. 6. In the following description, the present embodiment is mainly applied to the network architecture shown in fig. 5 as an example.

S71, the network equipment determines indication information, the indication information is used for indicating that an association relation is set according to a first mode, the association relation is a relation between an activated logic channel and a carrier, the carrier comprises a carrier associated with a deactivated logic channel, the activated logic channel and the deactivated logic channel belong to the same radio bearer, and data packets of the radio bearer are copied into at least three parts and are transmitted through at least three logic channels respectively;

S72, the terminal equipment determines that the association relationship between the activated logic channel and the carrier is set according to a first mode, the carrier comprises the carrier associated with the deactivated logic channel, the activated logic channel and the deactivated logic channel belong to the same radio bearer, and the data packet of the radio bearer is copied into at least three parts and is transmitted through at least three logic channels respectively;

and S73, the terminal equipment sets the association relation between the activated logical channel and the carrier wave according to the first mode.

The carrier includes a carrier associated with a deactivated logical channel, where the carrier associated with the deactivated logical channel refers to a carrier associated with the deactivated logical channel before deactivation.

Wherein, the at least three logical channels may include the activated logical channel and the deactivated logical channel. The number of activated logical channels may be one or more, for example, it may also be understood as at least one activated logical channel. The number of deactivated logical channels may be one or more, for example, also understood as at least one deactivated logical channel. The number of carriers may be one or more, for example, may also be understood as at least one carrier.

The carrier may comprise only the carrier with which the deactivated logical channel was associated prior to deactivation; or, the carriers may include all carriers of the terminal device in an activated state, all carriers of the terminal device in an activated state may include all carriers in an activated state associated with logical channels of the radio bearer, and may further include all carriers in an activated state not associated with any logical channel of the radio bearer, where all carriers of the terminal device in an activated state include carriers associated with the deactivated logical channels before deactivation; alternatively, the carriers may include other activated carriers of the terminal device except for the carrier associated with the activated logical channel, carriers associated with the deactivated logical channel before deactivation, and of course, all activated carriers not associated with any logical channel of the radio bearer.

The terminal device determines that the association relationship between the activated logical channel and the carrier is set in a first manner, and there may be different determination manners. For example, the network device may send the first signaling to the terminal device, and the terminal device receives the first signaling from the network device, which may refer to S74 in fig. 7, because S74 is not necessarily performed, and is drawn as a dotted line. In addition, S74, if executed, S74 occurs, for example, after S71 and before S72. Indication information is included in the first signaling, the indication information indicates that the association relationship between the logical channels and the carriers is set in the first way, the first signaling can also be used for configuring the repeat function of the radio bearer, or the first signaling can also be used for activating or deactivating one or more logical channels of the radio bearer. For example, the network device sends the indication information to the terminal device when configuring the duplicate function of the PDCP layer of the radio bearer, that is, the first signaling is also used for configuring the duplicate transmission function of the PDCP layer of the radio bearer, and then if the network device indicates to activate or deactivate one or more logical channels of the radio bearer again, the network device may not need to send the indication information again, and the terminal device may determine to set the association relationship between the activated logical channels and the carriers according to the previously received indication information. Alternatively, the association relationship between the activated logical channel and the carrier is set in a first manner, which may be specified by a protocol, and the terminal device may determine the association relationship without additional notification from the network device, which helps to save transmission overhead, in this case, the network device does not need to send the indication information, and then S71 may not be executed. The first signaling is, for example, Radio Resource Control (RRC) signaling, or MAC Control Element (CE), or Downlink Control Information (DCI), or RLC control PDU, or PDCP control PDU, or the like.

The RLC control PDU (RLC control PDU) is a kind of RLC PDU different from the RLC data PDU (RLC data PDU), and is distinguished from the RLC data PDU by the indication information of the header. Generally speaking, the RLC layer is used to transfer control information or feedback information, and in the embodiment of the present application, the RLC layer may be used to transmit control information related to a duplicate function of the PDCP layer, including an indication of activation/deactivation and the like and/or an indication of a carrier association relationship.

The PDCP control PDU (PDCP control PDU) is a PDCP PDU different from the PDCP data PDU (PDCP data PDU), and is distinguished from the PDCP data PDU by the indication information of the header. Generally speaking, the control information or feedback information for delivering the PDCP layer may be used to transmit control information related to a duplicate function of the PDCP layer in the embodiment of the present application, including an indication of activation/deactivation and the like and/or an indication of a carrier association relationship.

When determining the indication information, the network device may have determined which logical channels of the radio bearer are to be deactivated, for example, the first signaling is also used to deactivate one or more logical channels of the radio bearer, or the first signaling is also used to activate one or more logical channels of the radio bearer, then the activated logical channel and the deactivated logical channel indicated by the indication information may be explicit, for example, the network device indicates, through the first signaling, that logical channel 1 of the radio bearer is to be deactivated, and the radio bearer corresponds to logical channel 2 and logical channel 3, then the activated logical channel indicated by the network device through the indication information is logical channel 2 and logical channel 3, and the deactivated logical channel is logical channel 1. The first signaling may also be used to activate one or more logical channels of the radio bearer, where the network device configures a duplicate function of a PDCP layer for the radio bearer in advance, all logical channels of the radio bearer are activated, and then the network device instructs the terminal device to deactivate a part of logical channels of the radio bearer, and then the network device instructs the terminal device to activate logical channels of the radio bearer, where the activated logical channels are part or all of the logical channels that were deactivated before, and then the signaling used by the network device to instruct the terminal device to activate logical channels of the radio bearer may be the first signaling.

Or, when determining the indication information, the network device may not determine which logical channels of the radio bearer are to be deactivated, for example, the first signaling is signaling that the network device configures a duplicate function of a PDCP layer for the radio bearer, that is, after the network device sends the first signaling, all logical channels of the radio bearer are activated, and at this time, there is no deactivated logical channel. Then, the activated logical channel and the deactivated logical channel indicated by the indication information may be ambiguous, but it is only generic, that if there is a deactivated logical channel afterwards, the deactivated logical channel may be regarded as the deactivated logical channel, and the remaining activated logical channels except the deactivated logical channel may be regarded as the activated logical channel.

In addition, the data packets of the radio bearer are duplicated into at least three copies at the PDCP layer and transmitted through at least three logical channels, that is, the duplicated identical data packets are transmitted through at least three logical channels. Each of the at least three logical channels may transmit one data packet, that is, at least three logical channels transmit at least three data packets, and of the at least three data packets, there may be one data packet that is an original data packet, and other data packets are data packets obtained by copying the original data packet, and in short, the at least three data packets are collectively referred to as copied data packets or data packets copied at the PDCP layer. Hereinafter, the "copied packet" or the "copied packet at the PDCP layer" are both understood in the same manner.

In the embodiment of the present application, the first mode may include one or any combination of the following sub-modes:

a sub-mode 1, establishing an association relationship between the carrier and the activated logical channel according to the size sequence of the identification number (ID) of the carrier, wherein the association relationship is established between one carrier of the carrier and one logical channel of the activated logical channel each time; or,

a sub-mode 2, establishing an association relationship between the carrier and the activated logical channel according to the order of the quality of the channel of the carrier, wherein the association relationship is established between one carrier of the carrier and one logical channel of the activated logical channel each time; or,

a sub-mode 3, establishing an association relationship between the carrier and one of the activated logical channels; or,

a sub-mode 4, when the number of the activated logical channels is equal to 1, establishing an association relationship between the carrier and the activated logical channels; or,

a sub-mode 5, establishing an association relationship between the carriers and the activated logical channels according to the size sequence of the corresponding IDs of the deactivated logical channels, wherein all carriers associated with one deactivated logical channel before deactivation establish an association relationship with one activated logical channel; or,

And a sub-mode 6, establishing association relationship between each carrier of the carriers and one logic channel of the activated logic channels according to a random mode.

In the sub-mode 1, the carriers may be sequentially associated with the logical channels according to the order of the IDs of the carriers, the carriers may be sequentially associated with the activated logical channels according to the order of the IDs of the carriers and the order of the IDs of the logical channels, where the carrier with the largest corresponding ID may be associated with the logical channel with the largest corresponding ID, or the carrier with the largest corresponding ID may be associated with the logical channel with the smallest corresponding ID. For example, the carriers are carrier 3, carrier 5 and carrier 6, respectively, the activated logical channels are logical channel 1 and logical channel 2, respectively, then the carriers are sorted in the order from large ID to small ID of the carriers, carrier 6> carrier 5> carrier 3, the logical channels are sorted in the order from large ID to small ID of the logical channels, logical channel 2> logical channel 1, the carriers and the activated logical channels are sequentially associated in the order from large ID of the carriers and large ID of the logical channels, specifically, carrier 3 and logical channel 1 may be associated, carrier 5 and logical channel 2 may be associated, carrier 6 and logical channel 1 may be associated, or carrier 3 and logical channel 2 may be associated, carrier 5 and logical channel 1 may be associated, and associating the carrier 6 with the logical channel 2. If the association between the multiple carriers and the corresponding logical channels is established in a time-sharing manner, the association between the carrier with the largest ID of the carrier and the logical channel with the largest ID of the logical channel may be established first, or the association between the carrier with the smallest ID of the carrier and the logical channel with the smallest ID of the logical channel may be established first, and the specific details are not limited.

It is noted that, similar to sub-mode 1, another possible implementation may include one or more of the following steps (e.g., may include a and c of the following steps, or include b and c of the following steps, or include a, b, and c of the following steps):

a. the carriers are sorted according to the size of the carrier ID, and new IDs are sequentially assigned to the sorted carriers from 0 or 1 again, for example, the IDs of the sorted carriers are 0, 1, 2, 3, etc., or 1, 2, 3, etc., respectively.

b. The activated logical channels are sorted according to the size of the IDs of the logical channels, and new IDs are sequentially assigned to the sorted logical channels from 0 or 1 again, for example, the IDs of the sorted logical channels are 0, 1, 2, 3, etc., or 1, 2, 3, etc., respectively.

c. And determining the mapping relation of the carrier and the activated logical channel.

The manner of determining the mapping relationship may be one of the following manners in addition to the manner described in sub-manner 1:

and (4) performing modulo operation. Specifically, the number N of the activated logical channels is determined, then modulo operation is performed on the ID newly compiled by the carrier and N, and the carrier is associated to the corresponding logical channel according to the operation result. For example, if N is 2, if the result of modulo operation between the ID of a certain carrier and N is 0, the carrier is associated with a logical channel whose new ID is 0, or if the result of modulo operation between the ID of a certain carrier and N is 1, the carrier is associated with a logical channel whose new ID is 1.

The subsets are divided. If the number of the activated logical channels is 2, dividing the carrier into two subsets according to ID parity (ID without renumbering, namely original ID of the carrier) of the carrier, and establishing association relationship between the two subsets and the two logical channels, wherein one subset is established with one logical channel; or, the carriers (IDs that do not need to be renumbered, that is, original IDs of the carriers) in order according to the sizes of the IDs of the carriers are divided into two subsets from the middle, for example, a first subset and a second subset, where the first subset is a set of IDs before a dividing point, the second subset is a set of IDs after the dividing point, and this ID of the dividing point is, for example, an ID that is centered in values among the IDs of the carriers. Associating the first subset and the second subset with two logical channels, wherein one subset is associated with one logical channel, the number of carriers included in the first subset and the second subset may be equal (the total number of carriers is even), or the number of carriers included in the first subset and the second subset may not be equal (the total number of carriers is odd).

In the sub-mode 2, the carriers may sequentially establish an association relationship with the activated logical channels according to the order of the quality of the channel of the carriers, or the carriers may sequentially establish an association relationship with the activated logical channels according to the order of the quality of the channel of the carriers and the order of the size of the IDs of the logical channels, where the carrier with the best channel quality may establish an association relationship with the corresponding logical channel with the largest ID, or the carrier with the worst channel quality may also establish an association relationship with the corresponding logical channel with the smallest ID. For example, the carriers are carrier 3, carrier 5, and carrier 6, respectively, where the channel quality of carrier 3 is better than that of carrier 6, the channel quality of carrier 6 is better than that of carrier 5, the activated logical channels are logical channel 1 and logical channel 2, respectively, and logical channels are ordered according to the descending order of their IDs, which should be logical channel 2> logical channel 1. Then, according to the order of the quality of the channel of the carrier and the order of the size of the ID of the logical channel, the carrier and the activated logical channel are sequentially associated, specifically, the carrier 3 and the logical channel 1 may be associated, the carrier 6 and the logical channel 2 may be associated, and the carrier 5 and the logical channel 1 may be associated, or the carrier 3 and the logical channel 2 may be associated, the carrier 6 and the logical channel 1 may be associated, and the carrier 5 and the logical channel 2 may be associated. If the association relationship is established between the multiple carriers and the corresponding logical channels in a time-sharing manner, the association relationship may be established between the carrier with the best channel quality and the logical channel with the largest ID of the logical channel, or the association relationship may be established between the carrier with the worst channel quality and the logical channel with the smallest ID of the logical channel, which is not limited in particular. If the channel quality of some carriers associated with the logical channel is good, and the channel quality of other carriers associated with the logical channel is poor, which may not be able to perform a good function of transmitting the data packet duplicated in the PDCP layer, the embodiments of the present application propose to establish association relationships with the logical channels in sequence according to the order of the channel quality of the carriers, so that the channel quality of the carriers associated with each logical channel does not differ too much, the transmission quality of each logical channel is more balanced, and the task of transmitting the data packet duplicated in the PDCP layer is better completed. The channel quality of the carrier may be measured by a network device, and after the channel quality of the carrier is measured by the network device, the channel quality of the carrier may be sent to a terminal device, for example, the channel quality of the carrier may be sent to the terminal device by the network device through a first signaling, or the channel quality of the carrier may also be sent to the terminal device by the network device through another signaling. The channel quality of another carrier may also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (e.g. the ratio of received/transmitted Acknowledgements (ACKs)).

In sub mode 3, the carrier may be associated with one of the activated logical channels, that is, if there is only one of the activated logical channels, each of the carriers may be associated with the one activated logical channel, and if the number of the activated logical channels is greater than 1, each of the carriers may be associated with one of the plurality of activated logical channels. If the number of the activated logical channels is greater than 1, which activated logical channel is selected, which is not limited in the embodiments of the present application. For example, for a radio bearer, there is generally one primary logical channel, and the remaining logical channels are all secondary logical channels, so if the primary logical channel belongs to the activated logical channel, the carrier and the primary logical channel may be selected to be associated. For example, a radio bearer logical channel 1, logical channel 2, and logical channel 3 are used to transmit data packets duplicated in the PDCP layer, where logical channel 1 is the main logical channel, for example, logical channel 3 is deactivated, and logical channel 3 has an association relationship with carrier 3 before being deactivated, then carrier 3 may be associated with logical channel 1. Of course, it may also choose to associate the carrier with other activated logical channels of the activated logical channel except the main logical channel, and continuing with the above example, if the logical channel 3 is deactivated, the carrier 3 may be associated with the logical channel 1 or the logical channel 2. Therefore, it can be considered that the carrier may be associated with any one of the activated logical channels. If the carrier is associated with the main logical channel of the activated logical channel, the network device may indicate to the terminal device in the first signaling, for example, the ID of the main logical channel may be carried in the first signaling, so that the terminal device may determine to establish the association between the carrier and the main logical channel of the activated logical channel, or may specify through a protocol without an additional indication by the network device. If the association relationship between the carrier and any one of the activated logical channels is established, for example, the association relationship between the carrier and a randomly selected one of the activated logical channels is established, the network device may indicate to the terminal device in the first signaling, for example, the ID of the logical channel whose association relationship needs to be established may be carried in the first signaling, so that the terminal device may determine to establish the association relationship between the carrier and the logical channel.

In sub-mode 4, when the number of the activated logical channels is equal to 1, the carrier may be associated with the activated logical channel, and when the number of the activated logical channels is greater than 1, the association between the activated logical channels and the carrier is not changed, that is, for the activated logical channels, the original association between the activated logical channels and the carrier is maintained, and the carrier associated with the deactivated logical channels during deactivation is not associated with the activated logical channels. For example, a radio bearer transmits a data packet duplicated in the PDCP layer through logical channel 1, logical channel 3 and logical channel 3, where logical channel 1 has an association relationship with carrier 1, logical channel 2 has an association relationship with carrier 2 and carrier 3, and logical channel 3 has an association relationship with carrier 4, if both logical channel 2 and logical channel 3 are deactivated, the number of activated logical channels is 1, then both carrier 2 and carrier 3 associated with logical channel 2 before deactivation and carrier 4 associated with logical channel 3 before deactivation may be associated with logical channel 1, or, if only logical channel 3 is deactivated, the number of activated logical channels is 2, then the association relationship between logical channel 1 and carrier is unchanged, and the association relationship between logical channel 2 and carrier is also unchanged, logical channel 1 is still only associated with carrier 1 and logical channel 2 is still only associated with carrier 2 and carrier 3. This is done to simplify the implementation, for example, if the number of the activated logical channels is greater than 1, how to allocate the associated carriers to the activated logical channels needs a certain rule, which may involve modifying the protocol, so in sub-mode 4, if the number of the activated logical channels is greater than 1, the association relationship between the logical channels and the carriers may not be changed, which also does not need to modify the protocol, and if the number of the activated logical channels is equal to 1, it is only simple to directly associate the carriers with the activated logical channels.

In the sub-mode 5, the carriers are sequentially associated with the activated logical channels according to the size order of the IDs of the corresponding deactivated logical channels, which may be sequentially associated with the activated logical channels according to the size order of the IDs of the corresponding deactivated logical channels and according to the size order of the IDs of the activated logical channels, where the carrier corresponding to the deactivated logical channel with the largest ID may be associated with the logical channel with the largest corresponding ID, or the carrier corresponding to the deactivated logical channel with the smallest ID may be associated with the logical channel with the largest corresponding ID. Logical channel 3 and logical channel 4, where carrier 3 is associated with logical channel 3 before deactivation, and carrier 4, carrier and carrier 6 are associated with logical channel 4 before deactivation, and the activated logical channels are logical channel 1 and logical channel 2, respectively. The activated logical channels are ordered according to the descending order of the IDs of the logical channels, namely the logical channel 2> the logical channel 1, and the deactivated logical channels are ordered according to the descending order of the IDs of the logical channels, namely the logical channel 4> the logical channel 3. Then, according to the size sequence of the IDs of the logical channels, the carriers and the activated logical channels are sequentially associated, specifically, the carrier 3 associated with the logical channel 3 before deactivation may be associated with the logical channel 1, and the carriers 4, 5, and 6 associated with the logical channel 4 before deactivation may be associated with the logical channel 2, or the carrier 3 associated with the logical channel 3 before deactivation may be associated with the logical channel 2, and the carriers 4, 5, and 6 associated with the logical channel 4 before deactivation may be associated with the logical channel 1. This approach is simpler to implement than the sub-approaches 1, 2 that associate carriers in sequence.

In sub-mode 6, an association relationship between each carrier of the carriers and one logical channel of the activated logical channel may be established in a random manner, that is, an association relationship between the carrier and the activated logical channel may be completely established at random. Wherein, each carrier of the carriers establishes an association with which logical channel of the activated logical channels, the network device may indicate to the terminal device in the first signaling, and the terminal device may determine to establish an association between each carrier of the carriers and a corresponding logical channel of the activated logical channels.

Of course, the first method may include at least one of the above sub-methods, and may also include other methods for associating the carrier with the activated logical channel, which is not limited in this embodiment of the application.

The first way may be well defined in the protocol. Then, if the number of sub-modes included in the first mode specified in the protocol is greater than 1, it is also possible to indicate to the terminal device in cooperation with the signaling of the network device which sub-mode is used at all. For example, if the network device sends the first signaling to indicate to the terminal device that the association relationship between the activated logical channel and the carrier is set according to the first mode, the network device may only carry the identification information of the first mode without carrying a specific first mode in the first signaling, and the identification information of the first mode may be used as the indication information, for example, the identification information of the first mode is an ID of the first mode. For example, the first mode includes the foregoing sub-mode 2, the network device may carry the ID of the sub-mode 2 in the first signaling, so that the first signaling may indicate that the association relationship between the activated logical channel and the carrier is set according to the first mode, and after receiving the first signaling, the terminal device may determine, according to the ID of the sub-mode 2, that the association relationship between the activated logical channel and the carrier is set according to the sub-mode 2. This approach helps to reduce signaling overhead. If the number of the sub-modes included in the first mode specified in the protocol is equal to 1, that is, the first mode specified in the protocol is a sub-mode, it may also be unnecessary to indicate to the terminal device which sub-mode is used in cooperation with signaling of the network device, and the terminal device may determine, according to the protocol, which mode is the first mode, in which case the network device does not need to send the first signaling to the terminal device, or, if the first signaling is a repeated function for configuring a PDCP layer of the radio bearer or is used for activating or deactivating one or more logical channels of the radio bearer, the first signaling only needs to complete an original task without indicating that an association relationship between the activated logical channel and the carrier is set according to the first mode, which helps to save signaling overhead. Of course, even if the number of the sub-manners included in the first manner defined in the protocol is greater than 1, it may be that the terminal device is defined to use these multiple sub-manners to set the association relationship between the activated logical channel and the carrier, in this case, the network device may not need to send the second indication information to the terminal device, and the specific implementation is not limited.

Alternatively, the first mode may not be defined by a protocol. The network device may also carry the information of the specific first mode in the first signaling, and the information of the first mode may be used as the indication information. For example, the first mode includes the sub-mode 2 as described above, the network device may carry information of the sub-mode 2 in the first signaling, so that the first signaling may indicate that the association between the activated logical channel and the carrier is set according to the first mode, and after receiving the first signaling, the terminal device may determine, according to the information of the sub-mode 2, that the association between the activated logical channel and the carrier is set according to the sub-mode 2, and determine what the sub-mode 2 is. This way, the terminal device can obtain more specific information.

The first mode may include at least one of the above sub-modes, and other implementation forms may be possible besides this implementation form. Alternatively, it is to be understood that the first mode may include other modes in addition to at least one of the above described sub-modes.

As an implementation manner of the first manner, the first signaling may further carry a bitmap (bitmap) corresponding to each logical channel of all logical channels or a part of logical channels of the activated logical channels, and the bitmap of each logical channel may be used to indicate an association relationship between each logical channel and a carrier. For example, the correspondence may also be carried in the first signaling, so that the terminal device may specify the correspondence between the bitmap and the logical channel. Or, the first signaling may carry one or more bitmaps, where one bitmap is used to indicate an association relationship between one logical channel and a carrier, the logical channel corresponding to the one or more bitmaps is the activated logical channel, and the logical channel corresponding to the one or more bitmaps is all or part of the activated logical channel. In this case, the first manner may be a manner of setting an association relationship between the carrier and the activated logical channel according to a bitmap carried by the first signaling, or in other words, the first manner is a manner of setting an association relationship between the carrier and the activated logical channel according to the bitmap.

For example, the first signaling is signaling for configuring a repetition function of a PDCP layer of the radio bearer. For example, when configuring the duplicate function of the PDCP layer of the radio bearer, the terminal device may be enabled to make sure which carriers each logical channel of the radio bearer has an association relationship with through carrying, by the first signaling, a bitmap corresponding to each logical channel of all logical channels of the radio bearer, and in this case, the activated logical channel may be a logical channel of all the logical channels of the radio bearer, which is used for transmitting the data packet duplicated in the PDCP layer.

Alternatively, the first signaling is, for example, signaling for activating or deactivating one or more logical channels of the radio bearer.

For example, the first signaling is used to indicate to deactivate one or more logical channels of the radio bearer, and the first signaling may also carry a bitmap corresponding to each logical channel of all or part of the remaining activated logical channels of the radio bearer. The remaining activated logical channels may be activated logical channels remaining after the deactivation of one or more logical channels of the radio bearer through the first signaling.

For example, there are 3 logical channels corresponding to the repeating function of the PDCP layer of the radio bearer, which are respectively a logical channel 1, a logical channel 2, and a logical channel 3, where the logical channel 1 has an association relationship with the carrier 1 and the carrier 2, the logical channel 2 has an association relationship with the carrier 3, and the logical channel 3 has an association relationship with the carrier 4 and the carrier 5. The network device indicates, through the first signaling, to deactivate the logical channel 3, and then the remaining activated logical channels are the logical channel 1 and the logical channel 2, and then the network device may determine to establish an association relationship between the carrier associated with the logical channel 3 before being deactivated and the logical channel 1 and/or the logical channel 2, specifically, may establish an association relationship between the carrier associated with the logical channel 3 before being deactivated and the logical channel 1 or the logical channel 2, or establish an association relationship between the carrier associated with the logical channel 3 before being deactivated and the logical channel 1 and the logical channel 2. For example, if the network device determines that the carrier 4 associated with the logical channel 3 before deactivation is associated with the logical channel 1, and the carrier 5 associated with the logical channel 3 before deactivation is associated with the logical channel 2, the network device may generate a bitmap corresponding to the logical channel 1, and generate a bitmap corresponding to the logical channel 2. For example, because the logical channels 1 to 3 are originally associated with the carriers 1 to 5 in common, each bitmap may have 5 bits, each bit represents one carrier, one bitmap corresponds to the carriers 1 to 5 from high to low, and as to which carrier each bit of one bitmap corresponds, it may be predefined by a protocol, or configured in advance by a network device and notified to a terminal device. For a bitmap corresponding to a certain logical channel, if the value of a certain bit is "1", it indicates that the association relationship between the carrier and the logical channel is established, and if the value of a certain bit is "0", it indicates that the association relationship between the carrier and the logical channel is not established. For example, two bitmaps generated by the network device are both 5 bits, the bitmap corresponding to the logical channel 1 is 11010, and the bitmap corresponding to the logical channel 2 is 00101, which indicates that an association relationship is to be established between the logical channel 1 and the carrier 1, between the carrier 2 and the carrier 4, and between the logical channel 2 and the carrier 3, between the carrier 4 and the carrier 5, whereas the logical channel 1 originally has an association relationship with the carrier 1 and the carrier 2, and the logical channel 2 originally has an association relationship with the carrier 3, so that the terminal device can determine to establish an association relationship between the logical channel 1 and the carrier 3, and establish an association relationship between the logical channel 2 and the carriers 4 and 5.

In the above example, the first signaling carries bitmaps corresponding to all logical channels of the remaining activated logical channels, and in another case, the first signaling may carry bitmaps corresponding to part of logical channels of the remaining activated logical channels. For example, for the remaining activated logical channels, the association relationship between some logical channels and the carrier may not change, and then the first signaling may not carry the bitmaps corresponding to these logical channels, but only carry the bitmaps corresponding to the logical channels whose association relationship between the logical channels and the carrier has changed. For example, there are 3 logical channels corresponding to the repeated function of the PDCP layer of the radio bearer, which are respectively a logical channel 1, a logical channel 2, and a logical channel 3, where the logical channel 1 has an association relationship with the carrier 1 and the carrier 2, the logical channel 2 has an association relationship with the carrier 3, and the logical channel 3 has an association relationship with the carrier 4 and the carrier 5, and the network device indicates to deactivate the logical channel 3 through the first signaling, and then the remaining activated logical channels are the logical channel 1 and the logical channel 2, and then the network device may determine to establish an association relationship between the carrier associated with the logical channel 3 before being deactivated and the logical channel 1 and/or the logical channel 2. For example, the network device determines that the carrier 4 and the carrier 5 associated with the logical channel 3 before deactivation are both associated with the logical channel 2, that is, for the logical channel 1, the association with the carrier is unchanged. Then the network device may generate a bitmap corresponding to logical channel 2 without generating a bitmap corresponding to logical channel 1. For example, the bitmap has 5 bits, each bit represents a carrier, the bits from high to low correspond to carriers 1 to 5, and the bitmap may be 00111, which indicates that an association relationship is to be established between the logical channel 2 and the carrier 3, between the carrier 4 and the carrier 5, and the logical channel 2 originally has an association relationship with the carrier 3, so that the terminal device may determine to establish an association relationship between the logical channel 2 and the carriers 4 and 5.

Of course, for the remaining activated logical channels, even if the association between some logical channels and the carriers does not change, the bitmaps corresponding to these logical channels may be carried in the first signaling, that is, if the association between all the logical channels of the remaining activated logical channels and the carriers changes, the first signaling may carry the bitmaps corresponding to all the logical channels of the remaining activated logical channels, and if the association between some logical channels of the remaining activated logical channels and the carriers does not change, the first signaling may carry the bitmaps corresponding to all the logical channels of the remaining activated logical channels or may also carry the bitmaps corresponding to part of the logical channels of the remaining activated logical channels, which is not limited specifically.

For another example, the first signaling is used to indicate to activate one or more logical channels of the radio bearer, and the first signaling may also carry a bitmap corresponding to each logical channel of all or part of the remaining activated logical channels of the radio bearer. The remaining activated logical channels may be activated logical channels remaining after activating one or more logical channels of the radio bearer, and the remaining activated logical channels naturally include one or more logical channels activated by the first signaling. If the first signaling is used to indicate activation of one or more logical channels of the radio bearer, the one or more logical channels may be deactivated before, and at this time, re-activating the one or more logical channels involves a change in association relationship between the logical channels and the carriers, and the network device may indicate the association relationship between the logical channels and the carriers in a bitmap manner.

For example, there are 3 logical channels corresponding to the repeating function of the PDCP layer of the radio bearer, which are respectively a logical channel 1, a logical channel 2, and a logical channel 3, where the logical channel 1 has an association relationship with the carrier 1 and the carrier 2, the logical channel 2 has an association relationship with the carrier 3, and the logical channel 3 has an association relationship with the carrier 4 and the carrier 5. The network device has previously deactivated the logical channel 3, and after deactivating the logical channel 3, the carrier 4 associated with the logical channel 3 before deactivation has established an association with the logical channel 1, and the carrier 5 has established an association with the logical channel 2. And then, the network device indicates to activate logical channel 3 through the first signaling, and the remaining activated logical channels are logical channel 1, logical channel 2, and logical channel 3, so that the network device may reallocate the association relationship between the logical channels and the carriers. For example, the network device may restore the original association relationship between the logical channel and the carrier, that is, associate the logical channel 1 with the carrier 1 and the carrier 2, associate the logical channel 2 with the carrier 3, and associate the logical channel 3 with the carrier 4 and the carrier 5. Then the network device may carry 3 bitmaps in the first signaling, which correspond to logical channel 1 to logical channel 3, respectively, for example, each bitmap has 5 bits, each bit represents a carrier, and one bitmap corresponds to carrier 1 to carrier 5 from high to low. For example, the bitmap corresponding to the logical channel 1 is 11000, the bitmap corresponding to the logical channel 2 is 00100, and the bitmap corresponding to the logical channel 3 is 00011, and the terminal device can determine how to establish the association relationship between the logical channel and the carrier according to the 3 bitmaps. Of course, the original association relationship is recovered only by way of example, and the network device may reallocate the association relationship between the logical channel and the carrier without considering the original association relationship, for example, the network device may establish an association relationship between the carrier 1 and the logical channel 3.

In the above example, the first signaling carries bitmaps corresponding to all logical channels of the remaining activated logical channels, and in another case, the first signaling may carry bitmaps corresponding to part of logical channels of the remaining activated logical channels. For example, for the remaining activated logical channels, the association relationship between some logical channels and the carrier may not change, and then the first signaling may not carry the bitmaps corresponding to these logical channels, but only carry the bitmaps corresponding to the logical channels whose association relationship between the logical channels and the carrier has changed.

For example, there are 3 logical channels corresponding to the repeating function of the PDCP layer of the radio bearer, which are respectively a logical channel 1, a logical channel 2, and a logical channel 3, where the logical channel 1 has an association relationship with the carrier 1 and the carrier 2, the logical channel 2 has an association relationship with the carrier 3, and the logical channel 3 has an association relationship with the carrier 4 and the carrier 5. The network device has previously deactivated the logical channel 3, and after deactivating the logical channel 3, the carrier 4 associated with the logical channel 3 before deactivation has established an association with the logical channel 1, and the carrier 5 has established an association with the logical channel 2. And then, the network device indicates to activate logical channel 3 through the first signaling, and the remaining activated logical channels are logical channel 1, logical channel 2, and logical channel 3, so that the network device may reallocate the association relationship between the logical channels and the carriers. For example, the network device determines to associate logical channel 3 with carrier 1, that is, the association between logical channel 1 and logical channel 3 and the carrier will change, but the association between logical channel 2 and the carrier will not change. Then the network device may carry 2 bitmaps in the first signaling, which correspond to the logical channel 1 and the logical channel 3, respectively, for example, each bitmap has 5 bits, each bit represents one carrier, and one bitmap corresponds to the carrier 1 to the carrier 5 from the high bit to the low bit, respectively. For example, the bitmap corresponding to the logical channel 1 is 01010, the bitmap corresponding to the logical channel 3 is 10000, and the terminal device can determine how to establish the association relationship between the logical channel and the carrier according to the 2 bitmaps. It can be seen that, for the logical channel 2, the network device may not need to carry the corresponding bitmap in the first signaling, thereby contributing to saving signaling overhead.

Alternatively, if the previous signaling is used to indicate that one or more logical channels of the radio bearer are activated, the indication information included in the first signaling may also be used to indicate to restore the original association relationship between the logical channels of the radio bearer and the carriers, i.e. the original association relationship, that is, the association relationship between all the logical channels and the carriers before the one or more logical channels are deactivated. In this way, the first signaling may not need to carry bitmaps.

For example, there are 3 logical channels corresponding to the repeating function of the PDCP layer of the radio bearer, which are respectively a logical channel 1, a logical channel 2, and a logical channel 3, where the logical channel 1 has an association relationship with the carrier 1 and the carrier 2, the logical channel 2 has an association relationship with the carrier 3, and the logical channel 3 has an association relationship with the carrier 4 and the carrier 5. The network device has previously deactivated the logical channel 3, and after deactivating the logical channel 3, the carrier 4 associated with the logical channel 3 before deactivation has established an association with the logical channel 1, and the carrier 5 has established an association with the logical channel 2. And then, the network device indicates to activate logical channel 3 through the first signaling, and the remaining activated logical channels are logical channel 1, logical channel 2, and logical channel 3, so that the network device may reallocate the association relationship between the logical channels and the carriers. For example, the network device may restore the original association relationship between the logical channel and the carrier, that is, associate the logical channel 1 with the carrier 1 and the carrier 2, associate the logical channel 2 with the carrier 3, and associate the logical channel 3 with the carrier 4 and the carrier 5. Then, the network device only needs to carry the indication information, for example, the indication information may occupy 1 bit (bit), if the value of the 1 bit is "1", it indicates that the original association relationship is restored, and if the value of the 1 bit is "0", it indicates that the original association relationship is not restored. Taking the value of the 1 bit as "1" as an example, the terminal device may determine to restore the original association relationship, that is, to establish an association relationship between the logical channel 1 and the carrier 2, an association relationship between the logical channel 2 and the carrier 3, and an association relationship between the logical channel 3 and the carrier 4 and the carrier 5. After the logical channel is deactivated and activated, the original association relationship can be restored through simple indication information, excessive rules do not need to be set, and the realization is simpler.

The first signaling indicates the association relationship between the logical channel and the carrier in a way of carrying bitmap, and the indication way is relatively clear and simple, so that the terminal device can conveniently set according to the indication information. In addition, in the manner introduced above, the first signaling carries a bitmap, and in another case, the network device may further send a second signaling to the terminal device, where the second signaling may be used to indicate to activate or deactivate one or more logical channels of the radio bearer, the second signaling may carry a bitmap corresponding to each logical channel of all or part of the remaining activated logical channels of the radio bearer, and the bitmap of each logical channel is used to indicate an association relationship between each logical channel and a carrier. Or, the second signaling carries one or more bitmaps, one of the bitmaps is used for indicating the association relationship between one logical channel and the carrier, the logical channel corresponding to the one or more bitmaps is the remaining activated logical channel of the radio bearer, and the remaining activated logical channel is the remaining activated logical channel after the one or more logical channels of the radio bearer are deactivated according to the second signaling. In this case, the first manner may be a manner of setting an association relationship between the carrier and the activated logical channel according to a bitmap carried by another signaling, or it is understood that the first manner is a manner of setting an association relationship between the carrier and the activated logical channel according to the bitmap. If the second signaling is used to indicate activation of the one or more logical channels of the radio bearer, then the remaining activated logical channels are activated logical channels remaining after activation of the one or more logical channels of the radio bearer according to the second signaling, or if the second signaling is used to indicate deactivation of the one or more logical channels of the radio bearer, then the remaining activated logical channels are activated logical channels remaining after deactivation of the one or more logical channels of the radio bearer according to the second signaling. In this case, the network device does not send the bitmap to the terminal device through the first signaling including the indication information, but sends the bitmap to the terminal device through the additional second signaling, so that the indication information and the bitmap can be relatively independent. For example, the first signaling may be signaling for configuring a repetition function of a PDCP layer of the radio bearer, and the second signaling may be signaling for activating or deactivating one or more logical channels of the radio bearer after configuring the repetition function of the PDCP layer of the radio bearer. Of course, the embodiments of the present application are not limited to the specific implementation manners of the first signaling and the second signaling. If the bitmap is carried by the second signaling, the implementation manner of the bitmap, etc. can refer to the introduction of the bitmap carried by the first signaling in the foregoing. Whether the bitmap is carried by the first signaling or the second signaling depends on the specific implementation manner of the network device, or may be specified by a protocol, which is not limited specifically.

In addition, besides the implementation forms of the first mode described above, the first mode may have other implementation forms. Alternatively, the first mode may include one or any combination of the following embodiments, in addition to the above-described modes.

As an embodiment, the first mode may be a mode of releasing association between the first logical channel and the first carrier, and the first logical channel may be one of the remaining activated logical channels. In this manner, the indication information indicates, for example, the ID of the first logical channel and the ID of the first carrier, so that the terminal device can determine to release the association between the first logical channel and the first carrier. For example, for a first logical channel, there is an association relationship with multiple carriers, while the channel quality of the first carrier is poor, and the effect of the first carrier is not great for transmitting data packets duplicated at the PDCP layer, so the network device may indicate to release the association relationship between the first logical channel and the first carrier through the indication information. Wherein, if the first signaling is used for indicating the activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the activation of the one or more logical channels, and if the first signaling is used for indicating the deactivation of the one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the deactivation of the one or more logical channels.

Or, for this embodiment, it may also be understood that the first manner may be a manner of releasing association between at least one logical channel and a corresponding carrier, the at least one logical channel may be one or more logical channels of remaining activated logical channels, and for each logical channel of the at least one logical channel, the corresponding carrier may refer to all carriers or a part of carriers associated with the logical channel.

As another implementation, the first method may be to release the association between the first logical channel and the second carrier, and establish the association between the second carrier and the second logical channel, which is equivalent to moving the second carrier from the first logical channel to the second logical channel. The first logical channel and the second logical channel may be two of the remaining activated logical channels. In this manner, the indication information indicates, for example, the ID of the first logical channel, the ID of the second carrier, and the ID of the second logical channel, so that the terminal device can determine to release the association between the first logical channel and the second carrier and establish the association between the second carrier and the second logical channel. For example, if the first logical channel has an association relationship with the plurality of carriers, and the channel quality of the plurality of carriers is better, and the channel quality of the carrier having an association relationship with the second logical channel may not be good, the network device may instruct to disassociate the first logical channel from the second carrier, and establish an association relationship between the second carrier and the second logical channel, so as to associate the carrier with better channel quality for the second logical channel, so as to improve the transmission quality of the data packet duplicated at the PDCP layer. Wherein, if the first signaling is used for indicating the activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the activation of the one or more logical channels, and if the first signaling is used for indicating the deactivation of the one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the deactivation of the one or more logical channels.

Of course, in this embodiment, it is not limited to only moving one carrier, and the carriers may also be processed in batch, for example, the association between the first logical channel and the multiple carriers may be released, the association between each of the multiple carriers and one or more logical channels may be established, the association between the multiple logical channels and the corresponding carriers may be released, the association between the disassociated carrier and one or more logical channels may be established, and so on.

As still another embodiment, the first method may be a method of establishing an association between the first logical channel and a third carrier in an active state, where the third carrier is not associated with all logical channels of the radio bearer, and the first logical channel is one of the remaining active logical channels. That is, the third carrier has not previously been associated with any logical channel of the radio bearer, and the network device may indicate, by the indication information, that the third carrier is associated with the first logical channel. For example, the channel quality of the carrier associated with the first logical channel may not be good, and the channel quality of the third carrier is good, the network device may instruct to associate the third carrier with the first logical channel, so as to improve the transmission quality of the data packet duplicated at the PDCP layer. Wherein, if the first signaling is used for indicating the activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the activation of the one or more logical channels, and if the first signaling is used for indicating the deactivation of the one or more logical channels of the radio bearer, the remaining activated logical channels may be the activated logical channels remaining after the deactivation of the one or more logical channels.

Of course, in this embodiment, it is not limited to only moving one carrier, and the carriers may also be processed in batch, for example, association between the first logical channel and multiple carriers may be established, and the multiple carriers are all active carriers that do not establish association with all logical channels of the radio bearer, and so on.

In still another embodiment, the first manner may be a manner of establishing an association relationship between the first logical channel and a fourth carrier, the fourth carrier being a carrier indicated by the indication information, and the first logical channel being one of the activated logical channels. For example, the network device indicates, through the first signaling, to activate the first logical channel, the network device may indicate, through the indication information, carriers that need to establish an association relationship with the first logical channel, where the carriers that need to establish an association relationship with the first logical channel may be one or more carriers, for example, the indication information may include IDs of the carriers, so that after receiving the first signaling, the terminal device may determine to activate the first logical channel, and establish an association relationship between a carrier corresponding to the ID of the carrier included in the indication information and the first logical channel. The fourth carrier is any one of carriers required to establish an association relationship with the first logical channel. The carriers that need to be associated with the first logical channel may include at least one of carriers that are currently associated with other activated logical channels and carriers that do not have any associated relationship with any logical channel, then, if the carriers that need to be associated with the first logical channel include carriers that currently have an association with other activated logical channels, after receiving the first signaling, the terminal device needs to release the association relationship between the carriers and the logical channel with the association relationship established before, and then establish the association relationship between the carriers and the first logical channel, and if the carriers required to establish an association with the first logical channel include carriers that do not establish an association with any logical channel, the terminal device may directly establish the association relationship between the carriers and the first logical channel after receiving the first signaling.

As described above, various implementation forms of the first mode are introduced, and as to which of the first modes is adopted, the first mode may be defined by a protocol or configured in advance by a network device.

For example, if the logical channels of a radio bearer for transmitting the data packets duplicated in the PDCP layer are originally the first logical channel and the second logical channel, and then the network device instructs to activate the third logical channel, the logical channels of the radio bearer for transmitting the data packets duplicated in the PDCP layer become the first logical channel, the second logical channel, and the third logical channel, for example, the network device instructs to activate the third logical channel through the first signaling. Then, the network device may carry the bitmap corresponding to the first logical channel, the bitmap corresponding to the second logical channel, and the bitmap corresponding to the third logical channel in the first signaling to indicate the association relationship between the three logical channels and the carrier, so that the terminal device may associate the carrier with the corresponding logical channel according to 3 bitmaps. Of course, if the association relationship between the logical channel and the carrier in the first logical channel and the second logical channel is not changed, the network device may not carry the bitmap of the logical channel that is not changed in the first signaling, thereby saving signaling overhead and reducing the step of processing the first signaling by the terminal device.

Or, if the logical channels of one radio bearer for transmitting the data packet duplicated in the PDCP layer are originally the first logical channel and the second logical channel, and then the network device instructs to activate the third logical channel, the logical channels of the radio bearer for transmitting the data packet duplicated at the PDCP layer become the first logical channel, the second logical channel and the third logical channel, for example, the network device indicates to activate the third logical channel through the first signaling, the indication information included in the first signaling may indicate that the association relationship between the activated logical channel and the carrier is set in the first manner, then the terminal device may also set the association relationship between the activated logical channel and the carrier in the first manner, the first mode here includes, for example, at least one of the sub-mode 1, the sub-mode 2, the sub-mode 3, the sub-mode 4, the sub-mode 5, or the sub-mode 6 described above.

Or, if the logical channels of one radio bearer for transmitting the data packets duplicated at the PDCP layer are originally the second logical channel and the third logical channel, and then the network device instructs to activate the first logical channel, the logical channels of the radio bearer for transmitting the data packets duplicated at the PDCP layer become the first logical channel, the second logical channel, and the third logical channel. For example, the network device indicates to activate the first logical channel through the first signaling, the indication information included in the first signaling may include an ID of one carrier or IDs of multiple carriers, and the carrier corresponding to the ID of the carrier included in the indication information is the carrier that needs to establish the association relationship with the first logical channel, so after receiving the first signaling, the terminal device may establish the association relationship between the carriers and the first logical channel.

In this embodiment of the present application, a radio bearer transmits a data packet duplicated in a PDCP layer through at least three logical channels, and the indication information may indicate that an association relationship between an activated logical channel and at least one carrier is set according to a first manner, where the at least one carrier includes a carrier associated with a deactivated carrier before deactivation, that is, for a case where the radio bearer transmits the data packet duplicated in the PDCP layer through a plurality of logical channels, if a logical channel is deactivated, this embodiment of the present application provides a method for allocating a carrier associated with the deactivated logical channel among remaining activated logical channels. And the first mode can be various and is flexible.

In the embodiment shown in fig. 7, the radio bearer transmits the data packet duplicated in the PDCP layer through at least three logical channels, while it is also possible that the radio bearer continues to transmit the data packet duplicated in the PDCP layer through two logical channels. Under the condition that a radio bearer transmits a data packet duplicated in a PDCP layer through two logic channels, if the radio bearer corresponds to the two logic channels according to the prior art, the radio bearer is configured in advance, and the radio bearer can not change after the configuration, so that the data packet duplicated in the PDCP layer needs to be transmitted continuously through the logic channels configured in advance no matter the transmission quality of the configured logic channels is better or worse. Such an approach is likely to result in poor transmission quality of the duplicated data packets at the PDCP layer. In view of this, embodiments of the present application provide a second method for configuring a logical channel, in which a logical channel corresponding to a radio bearer for transmitting a data packet duplicated in a PDCP layer can be flexibly changed, so as to improve transmission quality of the data packet duplicated in the PDCP layer.

Please refer to fig. 8, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 or fig. 6 as an example. In addition, the method may be performed by two communication apparatuses, for example, a third communication apparatus and a fourth communication apparatus, where the third communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the third communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on chip may also be used. The same applies to the fourth communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, may also be other communication apparatuses, such as a system on a chip. The third communication device may be a network device, the fourth communication device is a terminal device, or both the third communication device and the fourth communication device are network devices, or both the third communication device and the fourth communication device are terminal devices, or the third communication device is a network device, and the fourth communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the third communication device is the network device, and the fourth communication device is the terminal device as an example. If the present embodiment is applied to the network architecture shown in fig. 5, therefore, the network device described below may be a network device in the network architecture shown in fig. 5, and the terminal device described below may be a terminal device in the network architecture shown in fig. 5. Alternatively, if the present embodiment is applied to the network architecture shown in fig. 6, therefore, the network device described below may be the first network device or the second network device in the network architecture shown in fig. 6, and the terminal device described below may be the terminal device in the network architecture shown in fig. 6. In the following description, the present embodiment is mainly applied to the network architecture shown in fig. 5 as an example.

S81, the network equipment determines to configure at least three logic channels for the wireless bearing of the terminal equipment;

s82, the network device sends first indication information to the terminal device, and the terminal device receives the first indication information from the network device, where the first indication information is used to indicate that the radio bearer is transmitted through a first logical channel and a second logical channel of the at least three logical channels, and the data packet of the radio bearer is duplicated and transmitted through the first logical channel and the second logical channel, respectively;

S83, the terminal device determines that the radio bearer is transmitted through the first logical channel and the second logical channel of the at least three logical channels according to the first indication information, wherein the data packet of the radio bearer is duplicated and transmitted through the first logical channel and the second logical channel, respectively.

In this embodiment, the network device may configure at least three logical channels for the repeating function of the PDCP layer of the radio bearer, and at a time, the network device may instruct, through two logical channels, to transmit the data packet duplicated at the PDCP layer by using the first indication information, so that the first indication information may be information that the network device originally selects a logical channel for transmitting the data packet duplicated at the PDCP layer, that is, the first logical channel and the second logical channel are the logical channels originally selected by the network device after configuring the at least three logical channels, or the first indication information may also be information that the network device subsequently changes a logical channel, that is, the first logical channel and the second logical channel are logical channels that the network device subsequently changes after initially selecting a logical channel, for example, the originally selected logical channels may be the first logical channel and the third logical channel, and then changing into the first logical channel and the second logical channel through the first indication information. It can be seen that, by the technical solution provided in the embodiment of the present application, a logical channel for transmitting the data packet duplicated in the PDCP layer can be flexibly changed, so that a logical channel with better communication quality can be selected to transmit the data packet duplicated in the PDCP layer, thereby improving transmission quality.

The first indication information may be transmitted through signaling such as RRC signaling, MAC CE, DCI, RLC control PDU, or PDCP control PDU, or may be transmitted through other signaling.

In addition, the network device may send configuration information to the terminal device, in addition to determining to configure at least three logical channels for the radio bearer to transmit the data packets duplicated in the PDCP layer, where the configuration information is used to indicate that the at least three logical channels are configured for the radio bearer, and after receiving the configuration information from the network device, the terminal device may determine that the at least three logical channels are configured for the radio bearer. The configuration information and the first indication information may be carried in a single signaling, for example, the signaling is a signaling for activating a duplicate function of the PDCP layer, that is, the signaling may perform several functions, one is to configure at least three logical channels for the radio bearer, another is to activate a duplicate function of the PDCP layer of the radio bearer, and yet another is to indicate that a data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel. Alternatively, the configuration information and the first indication information may be carried in different signaling, for example, the configuration information is carried in signaling for activating a repeating function of the PDCP layer, and the first indication information is carried in signaling for activating or deactivating one logical channel for transmitting a packet duplicated in the PDCP layer. Wherein, activating a logical channel for transmitting a packet duplicated at the PDCP layer means that the network device has previously instructed to deactivate the logical channel, and then subsequently may instruct to activate the logical channel again, and deactivating a logical channel for transmitting a packet duplicated at the PDCP layer means that the network device has previously instructed to activate the logical channel (e.g., may be activated when a repeat transmission function is activated, or activated after deactivation), and then subsequently may instruct to deactivate the logical channel again.

The configuration information may be transmitted through signaling such as RRC signaling, MAC CE, DCI, RLC control PDU, or PDCP control PDU, or may be transmitted through other signaling.

In addition, in the case that the radio bearer transmits the data packet duplicated in the PDCP layer through two logical channels, if according to the prior art, each logical channel of the radio bearer used for transmitting the data packet duplicated in the PDCP layer has an association relationship specifically with which carriers, and is configured in advance, and generally cannot be changed after configuration, the data packet duplicated in the PDCP layer still needs to be transmitted through the carriers configured in advance no matter whether the transmission quality of the configured carriers is good or bad. Such an approach is also likely to result in poor transmission quality of the data packets duplicated at the PDCP layer. In view of this, the embodiments of the present application propose that the carrier associated with the logical channel can also be flexibly changed.

For example, the terminal device may determine that association relationships between one or two activated logical channels of the first logical channel and the second logical channel are set in a first manner, which may have different determination manners, where the carriers include carriers associated with deactivated logical channels before deactivation, and the deactivated logical channels are deactivated logical channels other than the one or two activated logical channels in the at least three logical channels. For example, the network device determines second indication information, where the second indication information is used to indicate the terminal device to set an association relationship between one or two activated logical channels of the first logical channel and the second logical channel and the carrier according to the first manner, and the network device sends the second indication information to the terminal device, and after receiving the second indication information, the terminal device may determine the association relationship between one or two activated logical channels of the first logical channel and the second logical channel and the carrier according to the first manner. For example, if the first logical channel and the second logical channel of the second logical channel are deactivated, the first logical channel is an activated logical channel, and the carrier includes the carrier with which the second logical channel was associated before deactivation. Wherein, one or two activated logical channels of the first logical channel and the second logical channel include the first logical channel and/or the second logical channel (i.e. the first logical channel or the second logical channel, or the first logical channel and the second logical channel) depending on the activation status of the first logical channel and the second logical channel. In addition, of the at least three logical channels, all other logical channels except the first logical channel and the second logical channel may be regarded as deactivated logical channels, for example, the network device indicates, through the first indication information, to transmit the data packet duplicated in the PDCP layer through the first logical channel and the second logical channel, that is, may be regarded as other logical channels except the first logical channel and the second logical channel, which deactivate the at least three logical channels. When the network device configures at least three logical channels, the network device may also configure a carrier associated with each of the at least three logical channels, and then the network device configures associated carriers configured for other logical channels except for the first logical channel and the second logical channel, that is, carriers associated with the logical channels before being deactivated.

That is to say, the second indication information can flexibly indicate and set the association relationship between the activated logical channel and the carrier, the carrier configured for the logical channel is not invariable, and the network device can flexibly indicate the change, so that the carrier associated with the logical channel can be changed according to specific conditions, and the transmission quality is improved.

Or, the association relationship between one or two activated logical channels of the first logical channel and the second logical channel and the carrier is set according to a first mode, which may be specified by a protocol, for example, a specific first mode already specified in the protocol is specified, and the terminal device may determine through the protocol without additional notification by the network device, which is beneficial to saving transmission overhead.

The second indication information may be transmitted through signaling such as RRC signaling, MAC CE, DCI, RLC control PDU, or PDCP control PDU, or may be transmitted through other signaling.

When determining the second indication information, the network device may have already determined which logical channel of the first logical channel and the second logical channel is to be deactivated, for example, the signaling carrying the second indication information is further used to deactivate the first logical channel or the second logical channel, or the first signaling is further used to activate the first logical channel or the second logical channel, then the activated logical channel or the deactivated logical channel indicated by the second indication information may be explicit, for example, the network device further indicates to deactivate the first logical channel of the radio bearer through the signaling carrying the second indication information, then one or both activated logical channels indicated by the network device through the second indication information are the second logical channel, and the deactivated logical channel is the first logical channel.

Or, when determining the second indication information, the network device may not determine which logical channel of the first logical channel and the second logical channel is to be deactivated, for example, the signaling carrying the second indication information is a signaling that the network device configures a duplicate function of the PDCP layer for the radio bearer, that is, after the network device sends the signaling carrying the second indication information, both the first logical channel and the second logical channel are activated, and at this time, the deactivated logical channel is not present. Then, the activated logical channel or the deactivated logical channel indicated by the second indication information may be ambiguous, but it is only generic, that if there is a deactivated logical channel afterwards, the deactivated logical channel may be regarded as the deactivated logical channel, and the remaining activated logical channels except the deactivated logical channel may be regarded as the activated logical channel.

The configuration information, the first indication information and the second indication information may be carried in a single signaling, for example, the signaling is a signaling for activating a repetition function of a PDCP layer, that is, the signaling may perform several functions, a first is to configure at least three logical channels for the radio bearer, a second is to activate the repetition function of the PDCP layer of the radio bearer, a third is to indicate that a data packet copied in the PDCP layer is transmitted through the first logical channel and the second logical channel, and a fourth is to indicate that an association relationship between one or both of the first logical channel and the second logical channel, which are activated, and a carrier is set according to a first method. Or, the configuration information, the first indication information, and the second indication information may also be carried in different signaling for transmission, where the three information may be carried in 3 different signaling for transmission, or part of the three information may be carried in one signaling, and the rest of the three information may be carried in another signaling. For example, the configuration information is carried in signaling for activating a repetition function of the PDCP layer and the first indication information and the second indication information are carried in signaling for activating or deactivating one logical channel for transmitting the data packet duplicated at the PDCP layer, or the configuration information and the first indication information are carried in signaling for activating a repetition function of the PDCP layer and the second indication information are carried in signaling for activating or deactivating one logical channel for transmitting the data packet duplicated at the PDCP layer, or the configuration information is carried in signaling for activating a repetition function of the PDCP layer, the first indication information is carried in signaling for activating one logical channel for transmitting the data packet duplicated at the PDCP layer, the second indication information is carried in signaling for deactivating one logical channel for transmitting the data packet duplicated at the PDCP layer, and so on.

a sub-mode 1, establishing an association relationship between the carrier and one or two activated logical channels according to the size sequence of the identification numbers (IDs) of the carriers, wherein the association relationship is established between one carrier of the carrier and one logical channel of the one or two activated logical channels each time; or,

a sub-mode 2, establishing an association relationship between the carrier and the one or two activated logical channels according to the order of the quality of the channel of the carrier, wherein the association relationship is established between one carrier of the carrier and one logical channel of the one or two activated logical channels each time; or,

a sub-mode 3, establishing association relationship between the carrier and one of the one or two activated logical channels; or,

a sub-mode 4, when the number of the one or two activated logical channels is equal to 1, establishing an association relationship between the carrier and the activated logical channels; or,

a sub-mode 5, establishing an association relationship between the carrier and the one or two activated logical channels according to the size sequence of the corresponding deactivated logical channel ID, wherein all carriers associated with one deactivated logical channel before deactivation establish an association relationship with one activated logical channel; or,

A sub-mode 6, establishing association relationship between each carrier of the carriers and one logical channel of the one or two activated logical channels according to a random mode; or,

the sub-method 7 and the second indication information include a first index, the first method is a method corresponding to the first index, and the first index is used for indicating an association relationship between a logical channel and a carrier. The first logical channel and the second logical channel correspond to at least two indexes, the correlation between the logical channel corresponding to the at least two indexes and the carrier wave is different, and the first index belongs to the at least two indexes.

In the sub-mode 1, the carriers may sequentially establish an association relationship with the one or two activated logical channels according to the size order of the IDs of the carriers, or the carriers may sequentially establish an association relationship with the one or two activated logical channels according to the size order of the IDs of the carriers and the size order of the IDs of the logical channels, where the carrier with the largest corresponding ID may establish an association relationship with the logical channel with the largest corresponding ID, or the carrier with the largest corresponding ID may also establish an association relationship with the logical channel with the smallest corresponding ID. For example, the carriers are carrier 3, carrier 5 and carrier 6, respectively, the activated logical channels are a first logical channel and a second logical channel, then the carriers are sorted in the order from the ID of the carrier to the ID of the carrier, carrier 6> carrier 5> carrier 3, the logical channels are sorted in the order from the ID of the logical channel to the ID of the logical channel, second logical channel > first logical channel, the carriers and the one or two activated logical channels are associated in sequence according to the size order of the IDs of the carriers and the size order of the IDs of the logical channels, specifically, carrier 3 and the first logical channel may be associated, carrier 5 and the second logical channel may be associated, carrier 6 and the first logical channel may be associated, or carrier 3 and the second logical channel may also be associated, carrier 5 is associated with the first logical channel 1 and carrier 6 is associated with the second logical channel. If the association between the multiple carriers and the corresponding logical channels is established in a time-sharing manner, the association between the carrier with the largest ID of the carrier and the logical channel with the largest ID of the logical channel may be established first, or the association between the carrier with the smallest ID of the carrier and the logical channel with the smallest ID of the logical channel may be established first, and the specific details are not limited.

b. And sorting the one or two activated logical channels according to the size of the IDs of the logical channels, and sequentially assigning new IDs to the sorted logical channels from 0 or 1 again, for example, the IDs of the sorted logical channels are 0, 1, etc., or 1, 2, etc., respectively.

c. Determining a mapping relation between the carrier and the one or two activated logical channels.

and (4) performing modulo operation. Specifically, the number N of the one or two activated logical channels is determined (N is a positive integer less than or equal to 2), then modulo operation is performed on the N by using the ID newly coded by the carrier, and the carrier is associated with the corresponding logical channel according to the operation result. For example, if N is 2, if the result of modulo operation between the ID of a certain carrier and N is 0, the carrier is associated with a logical channel whose new ID is 0, or if the result of modulo operation between the ID of a certain carrier and N is 1, the carrier is associated with a logical channel whose new ID is 1.

In the sub-mode 2, the carrier may sequentially establish an association relationship with the one or two activated logical channels according to the order of the channel quality of the carrier, or the carrier may sequentially establish an association relationship with the one or two activated logical channels according to the order of the channel quality of the carrier and the order of the IDs of the logical channels, where the carrier with the best channel quality may establish an association relationship with the corresponding logical channel with the largest ID, or the carrier with the worst channel quality may also establish an association relationship with the corresponding logical channel with the smallest ID. For example, the carriers are carrier 3, carrier 5, and carrier 6, respectively, where the channel quality of carrier 3 is better than that of carrier 6, the channel quality of carrier 6 is better than that of carrier 5, the activated logical channels are a first logical channel and a second logical channel, and the logical channels are ordered according to the descending order of their IDs, which should be the second logical channel > the first logical channel. Then, according to the order of the quality of the channel of the carrier and the size order of the IDs of the logical channels, the carrier and the activated logical channels are sequentially associated, specifically, the carrier 3 and the first logical channel may be associated, the carrier 6 and the second logical channel may be associated, and the carrier 5 and the first logical channel may be associated, or the carrier 3 and the second logical channel may be associated, the carrier 6 and the first logical channel may be associated, and the carrier 5 and the second logical channel may be associated. If the association relationship is established between the multiple carriers and the corresponding logical channels in a time-sharing manner, the association relationship may be established between the carrier with the best channel quality and the logical channel with the largest ID of the logical channel, or the association relationship may be established between the carrier with the worst channel quality and the logical channel with the smallest ID of the logical channel, which is not limited in particular. If the channel quality of some carriers associated with the logical channel is good, and the channel quality of other carriers associated with the logical channel is poor, which may not be able to perform a better function of transmitting the data packet duplicated in the PDCP layer, the embodiments of the present application propose to establish association relationships with the logical channels in sequence according to the order of the channel quality of the carriers, so that the channel quality of the carriers associated with each logical channel is not too different, the transmission quality of each logical channel is more balanced, and the function of transmitting the data packet duplicated in the PDCP layer is better completed. The channel quality of the carrier may be measured by a network device, and after the channel quality of the carrier is measured by the network device, the channel quality of the carrier may be sent to a terminal device, for example, the channel quality of the carrier may be sent to the terminal device by the network device through a signaling carrying the second indication information, or the channel quality of the carrier may also be sent to the terminal device by the network device through other signaling. The channel quality of another carrier may also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (e.g. the ratio of received/transmitted Acknowledgements (ACKs)).

In sub mode 3, the carrier may be associated with one of the one or two activated logical channels, that is, if there is only one of the one or two activated logical channels, each of the carriers may be associated with the one activated logical channel, and if the number of the one or two activated logical channels is 2, each of the carriers may be associated with one of the two activated logical channels. If the number of the activated logical channels is 2, that is, both the first logical channel and the second logical channel are activated logical channels, which activated logical channel is selected, which is not limited in the embodiment of the present application. For example, for a radio bearer, there is generally one primary logical channel, and the remaining logical channels are all secondary logical channels, then the carrier and the primary logical channel may be selected to be associated. For example, a first logical channel, a second logical channel, and a third logical channel are configured for a radio bearer, where the first logical channel is a main logical channel, and a data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel, for example, the data packet of the radio bearer is duplicated in two parts in the PDCP layer and is transmitted through the first logical channel and the second logical channel, respectively, the two data packets are data packets duplicated in the PDCP layer, and the first logical channel and the second logical channel are both active logical channels, for example, the third logical channel has an association with the carrier 3, then the carrier 3 may be associated with the first logical channel. Of course, it may also be selected to associate the carrier with other activated logical channels of the one or two activated logical channels except the primary logical channel, and continuing with the above example, the carrier 3 may be associated with the second logical channel. It can therefore be considered that the carrier may be associated with any one of the one or two activated logical channels. If the carrier is associated with the main logical channel of the activated logical channel, the network device may indicate the carrier to the terminal device in the second indication information, for example, the ID of the main logical channel may be included in the second indication information, so that the terminal device may determine to associate the carrier with the main logical channel of the one or two activated logical channels, or may also specify through a protocol without an additional indication from the network device. If the association relationship between the carrier and any one of the one or two activated logical channels is established, for example, the association relationship between the carrier and one of the one or two randomly selected logical channels is established, the network device may indicate the second indication information to the terminal device, for example, the second indication information may carry an ID of the logical channel for which the association relationship needs to be established, so that the terminal device may determine to establish the association relationship between the carrier and the logical channel.

In sub-mode 4, when the number of the one or two activated logical channels is equal to 1, the carrier may be associated with the activated logical channel, and when the number of the one or two activated logical channels is 2, the association between the one or two activated logical channels and the carrier is not changed, that is, the original association with the carrier is maintained for the one or two activated logical channels. For example, a radio bearer is configured with a first logical channel, a second logical channel and a third logical channel, the first logical channel is a main logical channel, and the data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel, for example, the data packet of the radio bearer is duplicated in two parts in the PDCP layer and is transmitted through the first logical channel and the second logical channel, respectively, and the first logical channel and the second logical channel are both active logical channels, wherein the first logical channel has an association relationship with the carrier 1, the second logical channel has an association relationship with the carrier 2 and the carrier 3, and the third logical channel has an association relationship with the carrier 4, if the second logical channel is deactivated, the number of the one or two active logical channels is 1, the carrier 2 and the carrier 3 associated with the second logical channel before deactivation, and the carrier 4 associated with the third logical channel before deactivation may establish an association relationship with the first logical channel, or, if the first logical channel or the second logical channel is both an activated logical channel, the number of the one or two activated logical channels is 2, the association relationship between the first logical channel and the carrier is not changed, the association relationship between the second logical channel and the carrier is also not changed, the first logical channel is still only associated with the carrier 1, and the second logical channel is still only associated with the carriers 2 and 3. This is done to simplify the implementation, for example, if the number of the one or two activated logical channels is 2, then there is a certain rule, which may involve modifying the protocol, how to allocate the associated carrier to the one or two activated logical channels, so in sub-mode 4, if the number of the one or two activated logical channels is 2, then the association between the one or two activated logical channels and the carrier may not be changed, so that there is no need to modify the protocol, and if the number of the one or two activated logical channels is equal to 1, then the carrier is directly associated with the activated logical channel, which is simpler.

In sub-mode 5, the carriers are sequentially associated with the one or two activated logical channels according to the size order of the IDs of the corresponding deactivated logical channels, which may be sequentially associated with the one or two activated logical channels according to the size order of the IDs of the corresponding deactivated logical channels and the size order of the IDs of the activated logical channels, where the carrier corresponding to the deactivated logical channel with the largest ID may be associated with the logical channel with the largest corresponding ID, or the carrier corresponding to the deactivated logical channel with the smallest ID may be associated with the logical channel with the largest corresponding ID. The deactivated logical channel herein may include other logical channels than the first logical channel and the second logical channel of the at least three logical channels, and if the first logical channel or the second logical channel is deactivated, the deactivated logical channel may further include a deactivated logical channel of the first logical channel and the second logical channel. For example, a first logical channel, a second logical channel, a third logical channel and a fourth logical channel are configured for one radio bearer, and the data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel, for example, the data packet of the radio bearer is duplicated in two parts in the PDCP layer and transmitted through the first logical channel and the second logical channel, respectively, and the first logical channel and the second logical channel are both active logical channels, where the first logical channel has an association relationship with carrier 1, the second logical channel has an association relationship with carrier 2 and carrier 3, the third logical channel has an association relationship with carrier 4, and the fourth logical channel has an association relationship with carrier 5 and carrier 6. The one or two activated logical channels are ordered according to the descending order of the IDs of the logical channels, and the deactivated logical channels are ordered according to the ascending order of the IDs of the logical channels, and the deactivated logical channels are ordered according to the fourth logical channels and the third logical channels. Then, according to the size sequence of the IDs of the logical channels, the carriers are sequentially associated with the one or two activated logical channels, specifically, the carrier 4 associated with the third logical channel before deactivation may be associated with the first logical channel, and the carriers 5 and 6 associated with the fourth logical channel before deactivation may be associated with the second logical channel, or the carrier 4 associated with the third logical channel before deactivation may be associated with the second logical channel, and the carriers 5 and 6 associated with the fourth logical channel before deactivation may be associated with the first logical channel. This approach is simpler to implement than the sub-approaches 1, 2 that associate carriers in sequence.

In the sub-mode 6, each carrier of the carriers may be associated with one logical channel of the one or two activated logical channels in a random manner, that is, the association between the carrier and the one or two activated logical channels is completely and randomly established. Wherein each of the carriers is associated with which of the one or two activated logical channels, the network device may indicate to the terminal device in the second indication information, and the terminal device may determine to associate each of the carriers with a corresponding logical channel of the one or two activated logical channels.

In the sub-mode 7, the first logical channel and the second logical channel may correspond to at least two indexes, and the association relationship between the logical channel and the carrier corresponding to the at least two indexes is different. For example, the at least two indexes include index 1 and index 2, the association between the logical channel corresponding to index 1 and the carrier is that the first logical channel has an association with carrier 1 and carrier 2, the second logical channel has an association with carrier 3, and the association between the logical channel corresponding to index 2 and the carrier is that the first logical channel has an association with carrier 1 and carrier 3, and the second logical channel has an association with carrier 2, it can be seen that the associations between the logical channels corresponding to different indexes and carriers are different. Then, the terminal device may determine the carrier associated with the first logical channel and the carrier associated with the second logical channel according to the first index, and if the second indication information includes the corresponding index, the terminal device naturally knows how to set the carrier associated with the first logical channel and the carrier associated with the second logical channel. For example, when the repetition function of the PDCP layer of the radio bearer is activated, the first logical channel has an association relationship with the carrier 1, and the second logical channel has an association relationship with the carrier 3, and the subsequent network device includes the first index through the second indication information, where the association relationship between the logical channel and the carrier corresponding to the first index is that the first logical channel has an association relationship with the carrier 1 and the carrier 2, and the second logical channel has an association relationship with the carrier 3, and then the terminal device may further establish an association relationship between the carrier 2 and the first logical channel.

The first mode may be well defined in the protocol, and then, if the number of sub-modes included in the first mode defined in the protocol is greater than 1, it may also be used in cooperation with signaling of the network device to indicate to the terminal device which sub-mode or sub-modes are used at all. For example, if the network device sends the second indication information to indicate to the terminal device that the association relationship between the activated logical channel and the carrier is set according to the first manner, the network device may only carry the identification information of the first manner without carrying specific information of the first manner in the second indication information, and the identification information of the first manner may be used as the indication information, for example, the identification information of the first manner is an ID of the first manner. For example, if the first mode includes the sub-mode 2 as described above, the network device may carry the ID of the sub-mode 2 in the second indication information, so that the second indication information may indicate that the association relationship between the one or two activated logical channels and the carrier is set according to the first mode, and after receiving the second indication information, the terminal device may determine, according to the ID of the sub-mode 2, that the association relationship between the one or two activated logical channels and the carrier is set according to the sub-mode 2. This approach helps to reduce signaling overhead. If the number of the sub-modes included in the first mode specified in the protocol is equal to 1, that is, the first mode specified in the protocol is a sub-mode, it may also be unnecessary to cooperate with signaling of the network device to indicate to the terminal device which sub-mode is used at all, and the terminal device may determine, according to the protocol, which mode the first mode is in, in which case the network device does not need to send second indication information to the terminal device, for example, the signaling carrying the second indication information is a repeated function of a PDCP layer used for configuring the radio bearer, or is used for activating or deactivating one or two logical channels of the radio bearer, and then the signaling carrying the second indication information only needs to complete an original task, and does not need to carry the second indication information, which helps to save signaling overhead. Of course, even if the number of the sub-manners included in the first manner defined in the protocol is greater than 1, it may be that the terminal device is defined to use these multiple sub-manners to set the association relationship between the one or two activated logical channels and the carrier, in this case, the network device may not need to send the second indication information to the terminal device, and the specific method is not limited.

Alternatively, the first mode may not be specified by the protocol, and the network device may carry the specific information of the first mode in the second indication information. For example, the first mode includes the sub-mode 2 as described above, the network device may carry information of the sub-mode 2 in the second indication information, so that the second indication information may indicate that the association relationship between the one or two activated logical channels and the carrier is set according to the first mode, and after receiving the second indication information, the terminal device may determine, according to the information of the sub-mode 2, the association relationship between the one or two activated logical channels and the carrier is set according to the sub-mode 2, and determine what the sub-mode 2 is. This way, the terminal device can obtain more specific information.

As an implementation manner of the first manner, the second indication information may further carry a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel (that is, carry a bitmap corresponding to the first logical channel or a bitmap corresponding to the second logical channel, or a bitmap corresponding to the first logical channel and a bitmap corresponding to the second logical channel), where the bitmap of the first logical channel is used to indicate an association relationship between the first logical channel and the carrier, and the bitmap of the second logical channel is used to indicate an association relationship between the second logical channel and the carrier. For example, the correspondence may also be carried in the second indication information, so that the terminal device may specify the correspondence between the bitmap and the logical channel. In this case, the first manner may be a manner of setting an association relationship between the carrier and the one or two activated logical channels according to a bitmap included in the second indication information, or the first manner may be a manner of setting an association relationship between the carrier and the one or two activated logical channels according to the bitmap.

For example, the signaling carrying the second indication information is signaling for configuring a repetition function of a PDCP layer of the radio bearer. For example, when configuring the duplicate function of the PDCP layer of the radio bearer, the signaling may carry second indication information, that is, a bitmap corresponding to each of the first logical channel and the second logical channel of the radio bearer, so that the terminal device may determine which carriers the first logical channel and the second logical channel have an association relationship with respectively.

Or, the signaling carrying the second indication information is, for example, signaling for activating or deactivating the first logical channel or the second logical channel.

For example, the signaling carrying the second indication information is used to indicate that the first logical channel is deactivated, and then the second indication information may carry a bitmap corresponding to the second logical channel. Or for example, the signaling carrying the second indication information is used to indicate that the first logical channel is activated, and then the second indication information may carry a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel. Specifically, if the signaling carrying the second indication information is used to indicate that the first logical channel is activated, the second indication information may carry a bitmap corresponding to the first logical channel, and an association relationship between the second logical channel and the carrier may or may not change, and if the association relationship between the second logical channel and the carrier changes, the second indication information may carry a bitmap corresponding to the second logical channel, and if the association relationship between the second logical channel and the carrier does not change, the second indication information may carry a bitmap corresponding to the second logical channel, so that the indication is more definite, or the bitmap corresponding to the second logical channel may not be carried, thereby reducing signaling overhead.

Alternatively, if the previous signaling is used to indicate that the first logical channel is activated, the second indication information may also be used to indicate that the original association relationship between the first logical channel and the carrier is restored, so-called the original association relationship, that is, the association relationship between the first logical channel and the carrier before the first logical channel is deactivated. In view of transmitting the data packet duplicated at the PDCP layer only through the first logical channel and the second logical channel, the second indication information may also be regarded as an indication to restore the original association between the first logical channel and the carrier, and to restore the original association between the second logical channel and the carrier. In this manner, the second indication information may not need to include a bitmap.

For example, a first logical channel, a second logical channel and a third logical channel are configured for a radio bearer, and a data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel, for example, the data packet of the radio bearer is duplicated in two at the PDCP layer and transmitted through the first logical channel and the second logical channel, respectively, wherein the first logical channel has an association relationship with the carrier 1, the second logical channel has an association relationship with the carrier 2 and the carrier 3, and the third logical channel has an association relationship with the carrier 4, after the data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel as indicated by the first indication information, the first logical channel is indicated to be deactivated, and after the first logical channel is deactivated, the carrier 1 is associated with the second logical channel, for example. Then, the network device activates the first logical channel through a signaling instruction carrying second indication information, so that the second indication information can indicate to restore the original association relationship between the first logical channel and the carrier, and after receiving the second indication information, the terminal device can re-establish the association relationship between the carrier 1 and the first logical channel, so that the association relationship is restored that the first logical channel has the association relationship with the carrier 1, and the second logical channel has the association relationship with the carrier 2 and the carrier 3. For example, the second indication information may occupy 1 bit (bit), and if the value of the 1 bit is "1", it indicates that the original association relationship is restored, and if the value of the 1 bit is "0", it indicates that the original association relationship is not restored. After the logical channel is deactivated and activated, the original association relationship can be restored through simple second indication information, excessive rules do not need to be set, and the realization is simpler.

The second indication information introduced above indicates the association relationship between the logical channel and the carrier in a bitmap manner, and the indication manner is relatively clear and simple, so that the terminal device can conveniently set according to the indication information. In addition, in the manner introduced above, the second indication information includes a bitmap, and in another case, the network device may further send third indication information to the terminal device, where a signaling carrying the third indication information may be used to indicate activation or deactivation of the first logical channel or the second logical channel, the third indication information may also carry a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel, the bitmap of the first logical channel is used to indicate an association relationship between the first logical channel and the carrier, and the bitmap of the second logical channel is used to indicate an association relationship between the second logical channel and the carrier. In this case, the first manner may be a manner of setting an association relationship between the carrier and the one or two activated logical channels according to a bitmap carried by other signaling, or it is understood that the first manner is a manner of setting an association relationship between the carrier and the one or two activated logical channels according to the bitmap. In this case, the network device does not send a bitmap to the terminal device through the second indication information, but sends a bitmap to the terminal device through the additional third indication information, so that the second indication information and the bitmap can be relatively independent. If the third indication information includes bitmap, the implementation manner of bitmap, etc. can refer to the introduction that the second indication information includes bitmap in the foregoing. Whether the second indication information or the third indication information includes bitmap depends on the specific implementation manner of the network device, or may be specified by a protocol, which is not limited specifically.

The configuration information, the first indication information, the second indication information, and the third indication information may be carried in a single signaling, for example, the signaling is a signaling for activating a repetition function of a PDCP layer, that is, the signaling may perform several functions, a first one is to configure at least three logical channels for the radio bearer, a second one is to activate the repetition function of the PDCP layer of the radio bearer, a third one is to indicate that a data packet duplicated in the PDCP layer is transmitted through the first logical channel and the second logical channel, and a fourth one is to indicate that an association relationship between one or two activated logical channels of the first logical channel and the second logical channel and a carrier is set according to a first method. Or, the configuration information, the first indication information, the second indication information, and the third indication information may also be carried in different signaling for transmission, where the four information may be carried in 4 different signaling for transmission, or part of the four information may be carried in one signaling, and the rest of the four information may be carried in another signaling. For example, the configuration information is carried in signaling for activating a repetition function of the PDCP layer and the first indication information, the second indication information, and the third indication information are carried in signaling for activating or deactivating one logical channel for transmitting a packet duplicated at the PDCP layer, or the configuration information and the first indication information are carried in signaling for activating a repetition function of the PDCP layer and the second indication information and the third indication information are carried in signaling for activating or deactivating one logical channel for transmitting a packet duplicated at the PDCP layer, or the configuration information is carried in signaling for activating a repetition function of the PDCP layer, the first indication information and the second indication information are carried in signaling for activating one logical channel for transmitting a packet duplicated at the PDCP layer, the third indication information is carried in signaling for deactivating one logical channel for transmitting a packet duplicated at the PDCP layer, and so on.

As an embodiment, the first mode may be a mode of releasing association between the first logical channel and the first carrier, and the first logical channel may be an active logical channel. In this manner, the second indication information indicates, for example, the ID of the first logical channel and the ID of the first carrier, so that the terminal device can determine to release the association between the first logical channel and the first carrier. For example, for a first logical channel, there is an association relationship with multiple carriers, while the channel quality of the first carrier is poor, and the effect of the first carrier is not great for transmitting data packets duplicated at the PDCP layer, so the network device may indicate to release the association relationship between the first logical channel and the first carrier through the second indication information.

Or, for such an embodiment, it may also be understood that the first manner may be a manner of releasing association between at least one logical channel and a corresponding carrier, the at least one logical channel may be a first logical channel and/or a second logical channel (i.e., the first logical channel or the second logical channel, or the first logical channel and the second logical channel), and for each logical channel of the at least one logical channel, the corresponding carrier may refer to all carriers or a part of carriers associated with the logical channel. For example, the first scheme may be a scheme of releasing the association between the first logical channel and the carrier 1 and releasing the association between the second logical channel and the carrier 2.

As another embodiment, the first method may be to release the association between the first logical channel and the second carrier and establish the association between the second carrier and the second logical channel, which is equivalent to moving the second carrier from the first logical channel to the second logical channel. The first logical channel and the second logical channel may be active logical channels. In this manner, the second indication information indicates, for example, the ID of the first logical channel, the ID of the second carrier, and the ID of the second logical channel, so that the terminal device can determine to release the association between the first logical channel and the second carrier and establish the association between the second carrier and the second logical channel. For example, if the first logical channel has an association relationship with multiple carriers, and the channel quality of the multiple carriers is better, and the channel quality of the carrier having an association relationship with the second logical channel may not be good, the network device may instruct to release the association relationship between the first logical channel and the second carrier, and establish an association relationship between the second carrier and the second logical channel, so as to associate the carrier with better channel quality for the second logical channel, so as to improve the transmission quality.

Of course, in this embodiment, it is not limited to only moving one carrier, and the carriers may be processed in batch, for example, the association between the first logical channel and the plurality of carriers may be released, and the association between each of the plurality of carriers and one or more logical channels may be established, or the association between the first logical channel and the corresponding carrier may be released, the association between the carrier disassociated from the first logical channel and the second logical channel may be established, and the association between the second logical channel and the corresponding carrier may be released, the association between the carrier disassociated from the second logical channel and the first logical channel may be established, and so on.

As still another embodiment, the first method may be a method of establishing an association between the first logical channel and a third carrier, where the third carrier is an active carrier that is not associated with the first logical channel and the second logical channel, or the third carrier is an active carrier that is not associated with at least three logical channels of the radio bearer. That is, the third carrier has not previously been associated with any logical channel of the radio bearer, or has not been associated with the first logical channel and the second logical channel, and the network device may indicate, through the second indication information, that the third carrier is associated with the first logical channel. For example, the channel quality of the carrier associated with the first logical channel may not be good, and the channel quality of the third carrier is good, the network device may instruct to associate the third carrier with the first logical channel, thereby improving the transmission quality.

Of course, in this embodiment, it is not limited to only moving one carrier, and the carriers may also be processed in batch, for example, association relationships between the first logical channel and multiple carriers may be established, where the multiple carriers are all active carriers that do not establish an association relationship with the first logical channel and the second logical channel, or all are active carriers that do not establish an association relationship with at least three logical channels of the radio bearer, and so on.

In this embodiment, the network device may configure at least three logical channels for the repeating function of the PDCP layer of the radio bearer, and at a time, the network device may instruct, through two logical channels, the data packet duplicated at the PDCP layer to be transmitted through the two logical channels, for example, the data packet duplicated at the PDCP layer is duplicated in two parts and transmitted through the two logical channels, respectively, then the first indication information may be information that the network device originally uses to select a logical channel for transmitting the data packet duplicated at the PDCP layer, that is, the first logical channel and the second logical channel are the logical channels originally selected by the network device after configuring the at least three logical channels, or the first indication information may also be information that the network device subsequently changes the logical channels, that is, the first logical channel and the second logical channel are the logical channels that the network device changes after originally selecting the logical channels, for example, the initially selected logical channel may be the first logical channel and the third logical channel, and then changed to the first logical channel and the second logical channel by the first indication information. It can be seen that, by the technical solution provided in the embodiment of the present application, a logical channel for transmitting the data packet duplicated in the PDCP layer can be flexibly changed, so that a logical channel with better communication quality can be selected to transmit the data packet duplicated in the PDCP layer, thereby improving transmission quality.

In the foregoing, it is introduced that, in the case that the radio bearer transmits the data packet duplicated at the PDCP layer through two logical channels, if according to the prior art, the logical channels of the radio bearer for transmitting the data packet duplicated at the PDCP layer are specifically associated with which carriers, which are configured in advance, and generally cannot be changed after the configuration, the data packet duplicated at the PDCP layer needs to be continuously transmitted through the carriers configured in advance regardless of whether the transmission quality of the configured carriers is good or bad. Such an approach is likely to result in poor transmission quality. In view of this, the embodiments of the present application provide a third method for configuring a logical channel, in which a carrier associated with the logical channel can be flexibly changed, so as to improve transmission quality.

Please refer to fig. 9, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 5 or fig. 6 as an example. In addition, the method may be performed by two communication apparatuses, for example, a fifth communication apparatus and a sixth communication apparatus, where the fifth communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the fifth communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same is true for the sixth communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the sixth communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, or of course, other communication apparatuses such as a system on chip may also be used. The fifth communication device and the sixth communication device are not limited to be implemented, for example, the fifth communication device may be a network device, the sixth communication device is a terminal device, or both the fifth communication device and the sixth communication device are network devices, or both the fifth communication device and the sixth communication device are terminal devices, or the fifth communication device is a network device, and the sixth communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.

For convenience of introduction, in the following, the method is performed by the network device and the terminal device as an example, that is, the fifth communication device is the network device, and the sixth communication device is the terminal device as an example. If the present embodiment is applied to the network architecture shown in fig. 5, therefore, the network device described below may be a network device in the network architecture shown in fig. 5, and the terminal device described below may be a terminal device in the network architecture shown in fig. 5. Alternatively, if the present embodiment is applied to the network architecture shown in fig. 6, therefore, the network device described below may be the first network device or the second network device in the network architecture shown in fig. 6, and the terminal device described below may be the terminal device in the network architecture shown in fig. 6. In the following description, the present embodiment is mainly applied to the network architecture shown in fig. 5 as an example.

S91, the network device determines adjustment information, the adjustment information is used for adjusting the carrier associated with at least one logical channel, the at least one logical channel is configured for the radio bearer of the terminal device, and the data packets of the radio bearer are copied into at least one copy and transmitted through the at least one logical channel respectively;

S92, the network device sends a first signaling to the terminal device, the terminal device receives the first signaling from the network device, the first signaling includes the adjustment information, and the first signaling is other signaling except for RRC signaling;

and S93, the terminal equipment adjusts the carrier wave associated with the at least one logic channel according to the adjustment information.

The signaling other than the RRC signaling may be, for example, MAC CE, DCI, RLC control PDU or PDCP control PDU, and is not limited in particular.

In this embodiment of the present application, the network device may instruct, through the first signaling, to adjust the carrier associated with the at least one logical channel, where the first signaling is not an RRC signaling, so that the network device may dynamically adjust an association relationship between the logical channel and the carrier, for example, the logical channel may associate the carrier with better channel quality as much as possible, so as to improve transmission quality. In addition, in the prior art, if the association relationship between the logical channel and the carrier needs to be changed, the network device needs to instruct the terminal device to re-establish the radio bearer through RRC signaling, which is equivalent to that the association relationship between the logical channel and the carrier of the new radio bearer is different from the original radio bearer.

The first signaling is, for example, signaling for activating a repeating function of a PDCP layer of the radio bearer, or may also be signaling for activating or deactivating a first logical channel or a second logical channel of the radio bearer, which is not limited in particular. The first logical channel and the second logical channel are logical channels configured for the radio bearer to transmit the data packet duplicated in the PDCP layer, and the at least one logical channel belongs to the first logical channel and the second logical channel, for example, the at least one logical channel includes the first logical channel and/or the second logical channel (i.e., the first logical channel or the second logical channel, or the first logical channel and the second logical channel).

In this embodiment of the present application, the adjustment information is used to indicate to adjust a carrier associated with at least one logical channel, and the indication manner of the adjustment information may be multiple.

As a first embodiment of the adjustment information, the adjustment information may be used to indicate information of a carrier associated with each of the at least one logical channel after adjustment. After receiving the adjustment information, the terminal device knows the adjusted result, and the terminal device can adjust the carrier associated with at least one logical channel according to the carrier currently associated with each channel of the at least one logical channel and the carrier associated with each logical channel of the at least one logical channel after adjustment indicated by the adjustment information.

For example, before the network device sends the adjustment information, the first logical channel has an association relationship with the carrier 1, the second logical channel has an association relationship with the carriers 2 and 3, for example, the channel quality of the carrier 1 is poor, and the channel qualities of the carriers 2 and 3 are both good, the network device may instruct to change the carrier 2 or the carrier 3 to be associated with the first logical channel, for example, the adjustment information indicates that the carrier associated with the second logical channel after adjustment is the carrier 3, then the terminal device may release the association relationship between the carrier 2 and the second logical channel, and establish the association relationship between the carrier 2 and the first logical channel, so that the carrier associated with the second logical channel after adjustment is the carrier 3. Or for example, before the network device sends the adjustment information, the first logical channel has an association relationship with carrier 1 and carrier 2, the second logical channel has an association relationship with carrier 3 and carrier 4, and the adjustment information indicates that the adjusted carriers associated with the first logical channel are carrier 1 and carrier 3, and the adjusted carriers associated with the second logical channel are carrier 4, so that the terminal device may release the association relationship between carrier 2 and the first logical channel, release the association relationship between carrier 3 and the second logical channel, and establish the association relationship between carrier 3 and the first logical channel, so that the adjusted carriers associated with the first logical channel are carrier 1 and carrier 3, and the adjusted carriers associated with the second logical channel are carrier 4.

As a second implementation manner of the adjustment information, the adjustment information may be used to indicate information of a carrier to be adjusted corresponding to each logical channel of the at least one logical channel, where each carrier of the carrier to be adjusted has an association relationship with one logical channel of two logical channels, the two logical channels are configured for a radio bearer, and the two logical channels are used to transmit a data packet duplicated in the PDCP layer, for example, the data packet of the radio bearer is duplicated and transmitted through the two logical channels, respectively, and the two logical channels include at least one logical channel, and the two logical channels are the first logical channel and the second logical channel. After receiving the adjustment information, the terminal device may adjust the carrier associated with the at least one logical channel according to the carrier currently associated with each logical channel of the at least one logical channel and information of the carrier to be adjusted corresponding to each logical channel of the at least one logical channel indicated by the adjustment information. For example, the terminal device may release the association between the carrier to be adjusted and the original logical channel and establish the association between the carrier to be adjusted and the other logical channel of the two logical channels, or the terminal device may simply release the association between the carrier to be adjusted and the original logical channel and does not establish the association between the carrier to be adjusted and the other logical channel of the two logical channels, and how the terminal device handles at all may be specified by a protocol or configured by the network device.

For example, before the network device sends the adjustment information, the first logical channel has an association relationship with the carrier 1, the second logical channel has an association relationship with the carriers 2 and 3, for example, the channel quality of the carrier 1 is poor, and the channel qualities of the carriers 2 and 3 are both good, the network device may indicate that the carrier 2 or the carrier 3 is associated with the first logical channel instead, for example, the adjustment information indicates the carrier 3, and then the terminal device may release the association relationship between the carrier 3 and the second logical channel and establish the association relationship between the carrier 3 and the first logical channel. Or for example, before the network device sends the adjustment information, the first logical channel has an association relationship with the carrier 1, and the second logical channel has an association relationship with the carrier 2 and the carrier 3, for example, the channel quality of the carrier 3 is poor, the adjustment information may indicate the carrier 3, and then the terminal device may release the association relationship between the carrier 3 and the second logical channel.

As a third implementation manner of the adjustment information, the adjustment information may be used to indicate a carrier to be adjusted that has no association relationship with two logical channels and an adjustment manner, where the adjustment manner is used to set an association relationship between at least one logical channel and the carrier to be adjusted, the two logical channels are configured for a radio bearer, the two logical channels are used to transmit a data packet duplicated in the PDCP layer, and the two logical channels include at least one logical channel, and the two logical channels are the first logical channel and the second logical channel. After receiving the adjustment information, the terminal device may set an association relationship between the at least one logical channel and the carrier to be adjusted according to the adjustment manner and the carrier to be adjusted, that is, adjust the carrier associated with the at least one logical channel.

In the embodiment of the present application, the adjustment manner may include one or any combination of the following sub-manners:

a sub-mode 1, establishing an association relationship between a carrier to be adjusted and at least one logic channel according to the size sequence of the carrier ID, wherein the association relationship is established between one carrier of the carrier to be adjusted and one logic channel of the at least one logic channel each time; or,

a sub-mode 2, establishing an association relationship between a carrier to be adjusted and at least one logic channel according to the sequence of the quality of the channel of the carrier, wherein the association relationship is established between one carrier of the carrier to be adjusted and one logic channel of the at least one logic channel each time; or,

a sub-mode 3, establishing an association relationship between the carrier to be adjusted and one logical channel of at least one logical channel; or,

a sub-mode 4, when the number of at least one logic channel is equal to 1, establishing an association relationship between the carrier to be adjusted and the logic channel; or,

a sub-mode 5, establishing association relation between each carrier of at least one carrier and one logic channel of at least one logic channel in a random mode; or,

the sub-method 6 and the adjustment information include a first index, where the first mode is a mode corresponding to the first index, and the first index is used to indicate an association relationship between a logical channel and a carrier.

In the sub-mode 1, the carrier to be adjusted may sequentially establish an association relationship with the at least one activated logical channel according to the size order of the IDs of the carriers, or the carrier to be adjusted may sequentially establish an association relationship with the at least one activated logical channel according to the size order of the IDs of the carriers and according to the size order of the IDs of the logical channels, where the carrier with the largest corresponding ID may establish an association relationship with the logical channel with the largest corresponding ID, or the carrier with the largest corresponding ID may also establish an association relationship with the logical channel with the smallest corresponding ID. For example, the carriers to be adjusted are carrier 3, carrier 5 and carrier 6, respectively, and the at least one activated logical channel is a first logical channel and a second logical channel, then the carriers are sorted in order of ID of the carriers from large to small, carrier 6> carrier 5> carrier 3, the logical channels are sorted in order of ID of the logical channels from large to small, second logical channel > first logical channel, the carriers to be adjusted are associated with the at least one activated logical channel in sequence according to the size order of the IDs of the carriers and the size order of the IDs of the logical channels, specifically, carrier 3 may be associated with the first logical channel, carrier 5 may be associated with the second logical channel, and carrier 6 may be associated with the first logical channel, or carrier 3 may be associated with the second logical channel, carrier 5 is associated with the first logical channel 1 and carrier 6 is associated with the second logical channel. If the association between the multiple carriers and the corresponding logical channels is established in a time-sharing manner, the association between the carrier with the largest ID of the carrier and the logical channel with the largest ID of the logical channel may be established first, or the association between the carrier with the smallest ID of the carrier and the logical channel with the smallest ID of the logical channel may be established first, and the specific details are not limited.

a. sorting the carriers to be adjusted according to the size of the IDs of the carriers, and sequentially assigning new IDs to the sorted carriers from 0 or 1 again, for example, the IDs of the sorted carriers are 0, 1, 2, 3, etc., or 1, 2, 3, etc., respectively.

b. At least one logical channel is sorted according to the size of the ID of the logical channel, and new IDs are sequentially assigned to the sorted logical channels from 0 or 1 again, for example, the IDs of the sorted logical channels are 0, 1, or 1, 2, respectively.

c. And determining the mapping relation between the carrier to be adjusted and at least one logical channel.

and (4) performing modulo operation. Specifically, the number N of at least one logical channel is determined (N is a positive integer less than or equal to 2), then modulo operation is performed on the ID newly coded by the carrier and N, and the carrier to be adjusted is associated with the corresponding logical channel according to the operation result. For example, if N is 2, if the result of modulo operation between the ID of a certain carrier and N is 0, the carrier is associated with a logical channel whose new ID is 0, or if the result of modulo operation between the ID of a certain carrier and N is 1, the carrier is associated with a logical channel whose new ID is 1.

The subsets are divided. If the number of at least one logical channel is 2, dividing the carrier to be adjusted into two subsets according to the ID parity of the carrier (ID without renumbering, namely the original ID of the carrier), and establishing association relationship between the two subsets and the two logical channels, wherein one subset is established with one logical channel; or, the carriers (IDs that do not need to be renumbered, that is, original IDs of the carriers) in order according to the sizes of the IDs of the carriers are divided into two subsets from the middle, for example, a first subset and a second subset, where the first subset is a set of IDs before a dividing point, the second subset is a set of IDs after the dividing point, and this ID of the dividing point is, for example, an ID that is centered in values among the IDs of the carriers. Associating the first subset and the second subset with two logical channels, wherein one subset is associated with one logical channel, the number of carriers included in the first subset and the second subset may be equal (the total number of carriers to be adjusted is even), or the number of carriers included in the first subset and the second subset may not be equal (the total number of carriers to be adjusted is odd).

In the sub-mode 2, the carrier to be adjusted may sequentially establish an association relationship with the at least one activated logical channel according to the order of the channel quality of the carrier, or the carrier to be adjusted may sequentially establish an association relationship with the at least one activated logical channel according to the order of the channel quality of the carrier and the order of the IDs of the logical channels, where the carrier with the best channel quality may establish an association relationship with the corresponding logical channel with the largest ID, or the carrier with the worst channel quality may also establish an association relationship with the corresponding logical channel with the smallest ID. For example, the carriers to be adjusted are carrier 3, carrier 5, and carrier 6, respectively, where the channel quality of carrier 3 is better than that of carrier 6, the channel quality of carrier 6 is better than that of carrier 5, and the at least one activated logical channel is a first logical channel and a second logical channel, and the logical channels are ordered according to the order of their IDs from large to small, and should be the second logical channel > the first logical channel. Then, according to the order of the quality of the channel of the carrier and the size order of the IDs of the logical channels, an association relationship is sequentially established between the carrier to be adjusted and at least one activated logical channel, specifically, an association relationship may be established between the carrier 3 and the first logical channel, an association relationship between the carrier 6 and the second logical channel, and an association relationship between the carrier 5 and the first logical channel, or an association relationship may be established between the carrier 3 and the second logical channel, an association relationship between the carrier 6 and the first logical channel, and an association relationship between the carrier 5 and the second logical channel. If the association relationship is established between the multiple carriers and the corresponding logical channels in a time-sharing manner, the association relationship may be established between the carrier with the best channel quality and the logical channel with the largest ID of the logical channel, or the association relationship may be established between the carrier with the worst channel quality and the logical channel with the smallest ID of the logical channel, which is not limited in particular. If the channel quality of some carriers associated with the logical channel is good, and the channel quality of other carriers associated with the logical channel is poor, which may not be able to perform a better function of transmitting the data packet duplicated in the PDCP layer, the embodiments of the present application propose to establish association relationships with the logical channels in sequence according to the order of the channel quality of the carriers, so that the channel quality of the carriers associated with each logical channel is not too different, the transmission quality of each logical channel is more balanced, and the function of transmitting the data packet duplicated in the PDCP layer is better completed. The channel quality of the carrier may be measured by a network device, and after the channel quality of the carrier is measured by the network device, the channel quality of the carrier may be sent to a terminal device, for example, the channel quality of the carrier may be sent to the terminal device by the network device through a signaling carrying adjustment information, or the channel quality of the carrier may also be sent to the terminal device by the network device through other signaling. The channel quality of another carrier may also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (e.g. the ratio of received/transmitted Acknowledgements (ACKs)).

In sub-mode 3, the carrier to be adjusted may be associated with one activated logical channel of the at least one activated logical channel, that is, if there is only one activated logical channel, each carrier to be adjusted may be associated with the one activated logical channel, and if the number of the at least one activated logical channel is 2, that is, the activated logical channels are the first logical channel and the second logical channel, each carrier of the carrier to be adjusted may be associated with one activated logical channel of the two activated logical channels. If the number of the at least one active logical channel is 2, that is, the first logical channel and the second logical channel are both active logical channels, which active logical channel is selected, which is not limited in the embodiments of the present application. For example, for a radio bearer, there is generally one primary logical channel, and the remaining logical channels are all secondary logical channels, then the carrier and the primary logical channel may be selected to be associated. For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit a data packet duplicated in the PDCP layer, for example, the data packet of the radio bearer is duplicated in two parts in the PDCP layer and transmitted through the first logical channel and the second logical channel, respectively, the first logical channel is a main logical channel, and both the first logical channel and the second logical channel are active logical channels, for example, carrier 3 has not been associated with the first logical channel and the second logical channel before, then carrier 3 may be associated with the first logical channel. Of course, the carrier to be adjusted may also be selected to establish an association relationship with other activated logical channels of the at least one activated logical channel except the primary logical channel, and continuing with the above example, the carrier 3 may be established with the second logical channel. Therefore, it can be considered that the carrier to be adjusted may be associated with any one of the at least one activated logical channel. If the carrier to be adjusted is associated with the primary logical channel of the at least one activated logical channel, the network device may indicate the association to the terminal device in the adjustment information, for example, the adjustment information may include an ID of the primary logical channel, so that the terminal device may determine that the carrier to be adjusted is associated with the primary logical channel of the at least one activated logical channel, or may also specify through a protocol without an additional indication by the network device. If the association relationship between the carrier to be adjusted and any one of the at least one activated logical channel is established, for example, the association relationship between the carrier to be adjusted and one of the at least one activated logical channel randomly selected is established, the network device may indicate the adjustment information to the terminal device, for example, the adjustment information may carry an ID of the logical channel whose association relationship needs to be established, so that the terminal device may determine that the association relationship between the carrier to be adjusted and the logical channel is established.

In sub-mode 4, when the number of the at least one activated logical channel is equal to 1, the association relationship between the carrier to be adjusted and the activated logical channel may be established, and when the number of the at least one activated logical channel is 2, the association relationship between the at least one activated logical channel and the carrier is not changed, that is, for the at least one activated logical channel, the original association relationship between the at least one activated logical channel and the carrier is maintained. For example, a first logical channel and a second logical channel are configured for a radio bearer to transmit a data packet duplicated in the PDCP layer, where the first logical channel is a main logical channel, and both the first logical channel and the second logical channel are active logical channels, where the first logical channel has an association relationship with carrier 1, the second logical channel has an association relationship with carrier 2 and carrier 3, and carrier 4 has no association relationship with both the first logical channel and the second logical channel. If the second logical channel is deactivated, the number of the at least one activated logical channel is 1, the carrier 4 may establish an association relationship with the first logical channel, or, if the first logical channel or the second logical channel is both activated logical channels, the number of the at least one activated logical channel is 2, the association relationship between the first logical channel and the carrier is not changed, the association relationship between the second logical channel and the carrier is also not changed, the first logical channel is still only associated with the carrier 1, the second logical channel is still only associated with the carriers 2 and 3, and the carrier 4 is still not established an association relationship with the first logical channel and the second logical channel. This is done to simplify the implementation, for example, if the number of at least one activated logical channel is 2, then there is a certain rule, which may involve modifying the protocol, on how to allocate the associated carrier for the one or two activated logical channels, so in sub-mode 4, if the number of the one or two activated logical channels is 2, then the association between the at least one activated logical channel and the carrier may not be changed, and thus there is no need to modify the protocol, and if the number of the at least one activated logical channel is equal to 1, then the carrier to be adjusted is directly associated with the activated logical channel, which is simpler.

In the sub-mode 5, an association relationship between each carrier of the carriers to be adjusted and one logical channel of the at least one activated logical channel may be established in a random manner, that is, an association relationship between the carriers to be adjusted and the at least one activated logical channel may be completely established at random. The network device may indicate the adjustment information to the terminal device, and the terminal device may determine to establish an association relationship between each carrier of the carriers to be adjusted and a corresponding logical channel of the at least one activated logical channel. For example, a first logical channel and a second logical channel are configured for a radio bearer to transmit a data packet duplicated in the PDCP layer, where the first logical channel is a main logical channel, and both the first logical channel and the second logical channel are active logical channels, where the first logical channel has an association relationship with carrier 1, the second logical channel has an association relationship with carrier 2 and carrier 3, and carrier 4 has no association relationship with both the first logical channel and the second logical channel. The network device indicates the carrier 4, indicates that the adjustment mode is the sub-mode 5, and indicates the ID of the first logical channel in the adjustment information, and then the terminal device may determine that the carrier 4 is associated with the first logical channel.

In the sub-mode 7, the first logical channel and the second logical channel may correspond to at least two indexes, and the association relationship between the logical channel and the carrier corresponding to the at least two indexes is different. For example, the at least two indexes include index 1 and index 2, the association between the logical channel corresponding to index 1 and the carrier is that the first logical channel has an association with carrier 1 and carrier 2, the second logical channel has an association with carrier 3, and the association between the logical channel corresponding to index 2 and the carrier is that the first logical channel has an association with carrier 1 and carrier 3, and the second logical channel has an association with carrier 2, it can be seen that the associations between the logical channels corresponding to different indexes and carriers are different. Then, the terminal device may determine the carrier associated with the first logical channel and the carrier associated with the second logical channel according to the first index, and if the adjustment information includes the corresponding index, the terminal device naturally knows how to set the carrier associated with the first logical channel and the carrier associated with the second logical channel. For example, when the repetition function of the PDCP layer of the radio bearer is activated, the first logical channel has an association with the carrier 1, the second logical channel has an association with the carrier 3, and the carrier 2 has no association with both the first logical channel and the second logical channel. And the subsequent network device includes the first index through the adjustment information, and the association relationship between the logical channel corresponding to the first index and the carrier is that the first logical channel has an association relationship with the carrier 1 and the carrier 2, and the second logical channel has an association relationship with the carrier 3, so that the terminal device can also establish an association relationship between the carrier 2 and the first logical channel. Alternatively, when the duplicate function of the PDCP layer of the radio bearer is activated, the first logical channel has an association relationship with carrier 1 and carrier 2, and the second logical channel has an association relationship with carrier 3. And the subsequent network device includes the first index through the adjustment information, and the association between the logical channel corresponding to the first index and the carrier is that the first logical channel has an association with the carrier 1 and the carrier 3, and the second logical channel has an association with the carrier 2, so that the terminal device can release the association between the carrier 2 and the first logical channel, establish the association between the carrier 2 and the second logical channel, and release the association between the carrier 3 and the second logical channel, and establish the association between the carrier 3 and the first logical channel.

Of course, the adjustment manner may include at least one of the above sub-manners, and may also include another manner for establishing association between the carrier and the activated logical channel, which is not limited in this embodiment of the application.

The adjustment manner may be well defined in the protocol, for example, if the number of the sub-manners included in the adjustment manner defined in the protocol is greater than 1, it may also be used to indicate to the terminal device which sub-manner or sub-manners are used in cooperation with signaling of the network device. For example, the method of sending the adjustment information by the network device indicates to the terminal device that the association relationship between the at least one activated logical channel and the carrier to be adjusted is set according to the adjustment method, so that the network device does not need to carry information of a specific adjustment method in the adjustment information, for example, the identification information of the adjustment method is an ID of the adjustment method. For example, if the adjustment mode includes the sub-mode 2 as described above, the network device may carry the ID of the sub-mode 2 in the adjustment information, so that the adjustment information may indicate that the association relationship between the at least one activated logical channel and the carrier to be adjusted is set according to the adjustment mode, and after receiving the adjustment information, the terminal device may determine, according to the ID of the sub-mode 2, that the association relationship between the at least one activated logical channel and the carrier to be adjusted is set according to the sub-mode 2. This approach helps to reduce signaling overhead. Or, the adjustment mode has already been specified in the protocol, and no matter whether the adjustment mode specified in the protocol includes one or multiple sub-modes as above, the adjustment information does not need to carry information of the adjustment mode (including identification information of the adjustment mode), as long as the network device sends the adjustment information, the terminal device may adjust the association relationship between the carrier to be adjusted and the at least one logical channel according to the adjustment mode specified in the protocol and the information of the carrier to be adjusted included in the adjustment information, and at this time, the adjustment information may also be regarded as a trigger information.

Alternatively, the adjustment method may not be specified by a protocol, and the network device may also carry information of a specific adjustment method in the adjustment information. For example, if the adjustment mode includes the sub-mode 2, the network device may carry information of the sub-mode 2 in the adjustment information, so that the adjustment information may indicate that the association relationship between the at least one activated logical channel and the carrier to be adjusted is set according to the adjustment mode, and after receiving the adjustment information, the terminal device may determine, according to the information of the sub-mode 2, the association relationship between the at least one activated logical channel and the carrier to be adjusted according to the sub-mode 2, and determine what the sub-mode 2 is. This way, the terminal device can obtain more specific information.

Besides the above sub-modes, the adjusting mode may also include other implementation modes. Or it is to be understood that the adjustment may comprise other ways besides at least one of the above sub-ways.

As an implementation manner of the adjustment manner, the adjustment information may further include a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel (that is, carry the bitmap corresponding to the first logical channel or the bitmap corresponding to the second logical channel, or the bitmap corresponding to the first logical channel and the bitmap corresponding to the second logical channel), where the bitmap of the first logical channel is used to indicate an association relationship between the first logical channel and the carrier, and the bitmap of the second logical channel is used to indicate an association relationship between the second logical channel and the carrier. For example, the at least one logical channel includes a first logical channel and/or a second logical channel, when the at least one logical channel includes the first logical channel, the adjustment information includes a bitmap corresponding to the first logical channel, and when the at least one logical channel includes the second logical channel, the adjustment information includes a bitmap corresponding to the second logical channel. For example, the correspondence may also be carried in the adjustment information, so that the terminal device may specify the correspondence between the bitmap and the logical channel. In this case, the adjusting manner may be a manner of setting an association relationship between the carrier to be adjusted and the at least one activated logical channel according to a bitmap included in the adjustment information, or the adjusting manner may be a manner of setting an association relationship between the carrier to be adjusted and the at least one activated logical channel according to the bitmap.

For example, the first signaling is signaling for configuring a repetition function of a PDCP layer of the radio bearer. For example, when configuring the duplicate function of the PDCP layer of the radio bearer, the terminal device may make sure that the first logical channel and the second logical channel have an association relationship with which carriers respectively through the first signaling carrying the adjustment information, that is, the bitmap corresponding to each of the first logical channel and the second logical channel of the radio bearer.

Alternatively, the first signaling is, for example, signaling for activating or deactivating the first logical channel or the second logical channel.

For example, the first signaling is used to indicate that the first logical channel is deactivated, and the adjustment information may include a bitmap corresponding to the second logical channel. Or for example, the first signaling is used to indicate activation of the first logical channel, and the second indication information may carry a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel. Specifically, if the first signaling is used to indicate activation of the first logical channel, the adjustment information may carry a bitmap corresponding to the first logical channel, and the association between the second logical channel and the carrier may or may not change, if the association between the second logical channel and the carrier changes, the adjustment information may carry a bitmap corresponding to the second logical channel, and if the association between the second logical channel and the carrier does not change, the adjustment information may carry a bitmap corresponding to the second logical channel, so that the indication is more definite, or the adjustment information may not carry a bitmap corresponding to the second logical channel, thereby reducing signaling overhead.

Alternatively, if the previous signaling is used to indicate that the first logical channel is activated, the adjustment information may also be used to indicate that the original association relationship between the first logical channel and the carrier is restored, so-called original association relationship, that is, the association relationship between the first logical channel and the carrier before the first logical channel is deactivated. Since the data packet duplicated in the PDCP layer is transmitted only through the first logical channel and the second logical channel, the adjustment information may also be regarded as an instruction to restore the original association between the first logical channel and the carrier, and to restore the original association between the second logical channel and the carrier. In this manner, the adjustment information may not need to include a bitmap.

For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit data packets copied in the PDCP layer, where the first logical channel has an association relationship with the carrier 1, and the second logical channel has an association relationship with the carrier 2 and the carrier 3, the first logical channel is instructed to be deactivated after the repetition function of the PDCP layer of the radio bearer is activated, and the carrier 1 and the second logical channel are associated after the first logical channel is deactivated, for example. Then, the network device activates the first logical channel through the first signaling instruction, so the adjustment information may instruct to restore the original association relationship between the first logical channel and the carrier, and after the terminal device receives the adjustment information, the carrier 1 may be re-associated with the first logical channel, so the association relationship is restored that the first logical channel has an association relationship with the carrier 1, and the second logical channel has an association relationship with the carrier 2 and the carrier 3. For example, the adjustment information may occupy 1 bit (bit), if the value of the 1 bit is "1", it indicates that the original association relationship is restored, and if the value of the 1 bit is "0", it indicates that the original association relationship is not restored. After the logical channel is deactivated and activated, the original association relationship can be restored through simple adjustment information, excessive rules do not need to be set, and the realization is simpler.

The adjustment information introduced above indicates the association relationship between the logical channel and the carrier by including a bitmap, and the indication manner is relatively clear and simple, so that the terminal device can conveniently set according to the indication information. In addition, in the manner introduced above, the adjustment information includes a bitmap, and in another case, the network device may further send a second signaling to the terminal device, where the second signaling may be used to indicate activation or deactivation of the first logical channel or the second logical channel, the second signaling may also carry the bitmap corresponding to the first logical channel and/or the bitmap corresponding to the second logical channel, the bitmap of the first logical channel is used to indicate an association relationship between the first logical channel and the carrier, and the bitmap of the second logical channel is used to indicate an association relationship between the second logical channel and the carrier. In this case, the adjusting mode may be a mode in which the association relationship between the carrier to be adjusted and the at least one activated logical channel is set according to a bitmap carried by another signaling, or it is understood that the adjusting mode is a mode in which the association relationship between the carrier to be adjusted and the at least one activated logical channel is set according to the bitmap. In this case, the network device does not send the bitmap to the terminal device through the adjustment information, but sends the bitmap to the terminal device through an additional second signaling, so that the adjustment information and the bitmap can be relatively independent. If the second signaling includes bitmap, the implementation manner of bitmap, etc. can refer to the introduction that the adjustment information includes bitmap in the foregoing. Whether the adjustment information or the second signaling includes bitmap depends on the specific implementation manner of the network device, or may be specified by a protocol, which is not limited specifically.

Besides the above described implementation forms of the adjustment method, other implementation forms of the adjustment method are also possible. Alternatively, besides the above-described modes, the adjusting mode may include one of the following several embodiments or any combination thereof.

As an embodiment, the adjusting manner may be a manner of releasing association between the first logical channel and the first carrier, and the first logical channel may be an activated logical channel. In this manner, the adjustment information indicates, for example, the ID of the first logical channel and the ID of the first carrier, so that the terminal device can determine to release the association between the first logical channel and the first carrier. For example, for a first logical channel, there is an association relationship with multiple carriers, while the channel quality of the first carrier is poor, and the effect of the first carrier is not great for transmitting data packets duplicated in the PDCP layer, so the network device may instruct to release the association relationship between the first logical channel and the first carrier through the adjustment information.

Or, for this embodiment, it may also be understood that the adjusting manner may be a manner of releasing an association relationship between at least one logical channel and a corresponding carrier, where the at least one logical channel may be a first logical channel and/or a second logical channel (i.e., the first logical channel or the second logical channel, or the first logical channel and the second logical channel), and for each logical channel of the at least one logical channel, the corresponding carrier may refer to all carriers or a part of carriers associated with the logical channel. For example, the adjustment method may be a method of releasing the association between the first logical channel and the carrier 1 and releasing the association between the second logical channel and the carrier 2.

As another embodiment, the adjusting manner may be to release the association relationship between the first logical channel and the second carrier, and establish the association relationship between the second carrier and the second logical channel, which is equivalent to moving the second carrier from the first logical channel to the second logical channel. The first logical channel and the second logical channel may be active logical channels. In this manner, the adjustment information indicates, for example, the ID of the first logical channel, the ID of the second carrier, and the ID of the second logical channel, so that the terminal device can determine to release the association between the first logical channel and the second carrier and establish the association between the second carrier and the second logical channel. For example, if the first logical channel has an association relationship with multiple carriers, and the channel quality of the multiple carriers is better, and the channel quality of the carrier having an association relationship with the second logical channel may not be good, the network device may instruct to release the association relationship between the first logical channel and the second carrier, and establish an association relationship between the second carrier and the second logical channel, so as to associate the carrier with better channel quality for the second logical channel, so as to improve the transmission quality.

As another embodiment, the adjustment method may be a method of establishing an association relationship between the first logical channel and a third carrier, where the third carrier is an active carrier that is not associated with the first logical channel and the second logical channel. That is, the third carrier has not previously been associated with any logical channel of the radio bearer, and the network device may indicate that the third carrier is associated with the first logical channel by the adjustment information. For example, the channel quality of the carrier associated with the first logical channel may not be good, and the channel quality of the third carrier is good, the network device may instruct to associate the third carrier with the first logical channel, thereby improving the transmission quality.

Of course, in this embodiment, it is not limited to only moving one carrier, and the carriers may be processed in batch, for example, association between the first logical channel and multiple carriers may be established, and all the multiple carriers are activated carriers that do not establish association with the first logical channel and the second logical channel, and so on.

As described above, various implementation forms of the adjustment method are introduced, and as to which adjustment method is adopted, the adjustment method may be specified by a protocol or configured in advance by a network device.

In this embodiment of the present application, the network device may instruct, through the first signaling, to adjust the carrier associated with the at least one logical channel, where the first signaling is not an RRC signaling, so that the network device may dynamically adjust an association relationship between the logical channel and the carrier, for example, the logical channel may associate the carrier with better channel quality as much as possible, so as to improve transmission quality.
