This application requires the priority of the Chinese patent application filed on December 10, 2018 in the Chinese Patent Office, with the application number 201811504295.0 and the application name "a method and equipment for configuring logical channels", the entire contents of which are incorporated herein by reference Applying.

Technical field

This application relates to the field of communication technology, and in particular, to a method and device for configuring logical channels.

Background technique

The duplication function of the PDCP layer is introduced in the 5th generation (5G) system. The duplication of the PDCP layer usually refers to copying the data packets carried by the radio into two identical packets (that is, duplicate packets), and then the two data packets are separately delivered to two different radio link controls (RLC) The entity transmits, and then transmits to the media 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 (packet data unit, PDU), because only through different MAC PDU transmission, one of the MAC The loss of PDU will not affect the transmission of another MAC PDU, which is equivalent to double the reliability. Therefore, two data packets can be transmitted to different MAC entities through different logical channels, and finally two MAC PDUs are formed to be transmitted on different carriers.

At present, the duplication of the PDCP layer is limited to one radio bearer transmitting data packets copied at the PDCP layer through two RLC entities and two logical channels. For example, when the repeat 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 moment, after the repetition function of the PDCP layer of the radio bearer is deactivated, only logical channel 1 is still working. At this time, in order to increase the transmission capacity, the data in logical channel 1 can be performed on all available carriers transmission. However, when the repetition of the PDCP layer is not limited to two RLC entities and two logical channels, how to use it after deactivation is still an urgent problem to be solved.

Summary of the invention

Embodiments of the present application provide a method and a device for configuring a logical channel, which are used to solve the technical problem of how to allocate carriers corresponding to the logical channel after a logical channel is deactivated.

In a first aspect, a first method for configuring a logical channel is provided.

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

In the embodiment of the present application, the wireless bearer transmits the copied data packet through at least three logical channels, the data packet is copied at the PDCP layer, and the indication information may indicate that the activated logical channel is set according to the first manner and at least The association relationship between one carrier, at least one carrier includes the carrier that the deactivated carrier was associated with before the deactivation, that is, for the case that the radio bearer transmits the data packet copied at the PDCP layer through multiple logical channels, If a logical channel is deactivated, the embodiment of the present application provides a method for allocating the carrier associated with the deactivated logical channel among the remaining activated logical channels. In addition, if a logical channel is activated, the embodiments of the present application provide a method for reallocating a carrier to each activated logical channel.

With reference to the first aspect, in a possible implementation manner of the first aspect, the carrier includes only the carrier associated with the deactivated logical channel before deactivation; or, the carrier includes the All carriers in the activated state, all carriers in the activated state of the terminal device include carriers associated with the deactivated logical channel before deactivation; or, the carrier includes all except the activation of the terminal device The carrier in the activated state other than the carrier associated with the logical channel of the terminal, the carrier in the activated state other than the carrier associated with the activated logical channel, including the deactivated The carrier associated with the logical channel before deactivation.

The carrier may include only the carrier associated with the deactivated logical channel before deactivation, and only need to reassign the carrier associated with the deactivated carrier before, the number of carriers to be allocated is less, and the workload is less . Alternatively, the carrier may also include all carriers in the activated state of the terminal device, which is equivalent to reallocating all carriers in the activated state of the terminal device, and all carriers in the activated state of the terminal device may also include all carriers that have not been previously connected. Any carrier associated with a logical channel can associate more carriers with the logical channel and improve the transmission quality of the data packets copied at the PDCP layer.

For example, if the channel quality of some carriers associated with logical channels is relatively good, and the channel quality of some logical channels is relatively poor, it may not be able to play the role of repetition of the PDCP layer. The carrier establishes an association relationship with the activated logical channel according to the order of the channel quality of the carrier, so that the channel quality of the carrier associated with each logical channel can be made more balanced, and the data packet copied at the PDCP layer can be improved Transmission quality. Alternatively, the carrier may be associated with one logical channel of the activated logical channel, so that there is no need to allocate the carrier among multiple logical channels, and the method is relatively simple. Alternatively, the carrier associated with a deactivated logical channel before deactivation may be unified to establish an association relationship with an activated logical channel, which is equivalent to allocating with the logical channel as the granularity, which simplifies the allocation process.

Alternatively, the first signaling may also indicate the establishment of the association relationship between the first logical channel and the third carrier, which is equivalent to including the carrier that has not previously established the association relationship with the logical channel into the scope of establishing the association relationship, for example, the channel of the third carrier The quality is good, so after establishing an association relationship with the first logical channel, it helps to improve the transmission quality of the first logical channel.

detailed description

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

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

1) Terminal devices, including devices that provide voice and/or data connectivity to users, for example, may include handheld devices with wireless connection capabilities, or processing devices connected to wireless modems. The terminal device can communicate with the core network via a radio access network (RAN) and exchange voice and/or data with the RAN. The terminal equipment may include user equipment (user equipment, UE), wireless terminal equipment, mobile terminal equipment, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile station), mobile station (mobile), remote Remote station, access point (AP), remote terminal equipment (remote terminal), access terminal equipment (access terminal), user terminal equipment (user terminal), user agent (user agent), or user Equipment (user device), etc. For example, it may include a mobile phone (or called a “cellular” phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, built-in or on-board mobile device, smart wearable device, and the like. For example, personal communication service (PCS) telephones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (wireless local loop (WLL) stations, personal digital assistants (personal digital assistants, PDA), and other equipment. It also includes restricted devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power. Examples include bar code, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners and other information sensing equipment.

As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices can also be referred to as wearable smart devices. It is a general term for applying wearable technology to intelligently design everyday wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only a hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction. Generalized wearable smart devices include full-featured, large-sized, complete or partial functions that do not depend on smartphones, such as: smart watches or smart glasses, and only focus on a certain type of application functions, and need to cooperate with other devices such as smartphones Use, such as all kinds of smart bracelets, smart helmets, smart jewelry for sign monitoring.

2) Network equipment, for example, including access network (AN) equipment. An access network device such as a base station (for example, an access point) may refer to a device that communicates with a wireless terminal device through one or more cells on an air interface in an access network. The network device can be used to convert received air frames and Internet Protocol (IP) packets to each other as a router between the terminal device and the rest of the access network, where the rest of the access network can include an IP network. The network equipment can also coordinate attribute management of the air interface. For example, the network equipment may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-A), or It may also include the fifth generation mobile communication technology (the fifth generation, 5G) new radio (NR) system, the next generation node B (next generation node B, gNB), or it may also include a cloud access network (cloud The centralized unit (CU) and distributed unit (DU) in the radio access network (CloudRAN) system are not limited in the embodiments of the present application.

3) Dual connectivity (DC), that is, the terminal device connects two base stations simultaneously. The two base stations connected by the terminal equipment may be base stations under the same wireless access technology, for example, both are base stations in the LTE system or both are base stations in the NR system, or the two base stations connected by the terminal equipment may also be different wireless connections. Base stations under the technology, for example, one is a base station in the LTE system and the other is a base station in the NR system.

4) Carrier aggregation (CA), CA technology can aggregate multiple component carriers (CC) to provide services for a terminal device, achieve a larger transmission bandwidth, and effectively improve the upstream and downstream transmission rates.

5) The logical channel is associated with the carrier, or the logical channel is associated with the carrier, or it may be called that the logical channel and the carrier have a binding relationship or a binding transmission relationship, etc., including but not limited to, if configured in the logical channel Indicates that certain carriers are allowed to be used, it means that the data transmitted in the logical channel can be transmitted on these carriers, or the resources on these carriers can be allocated to the logical channel. In this case, it can be called that the logical channel is associated with these carriers. Further, the data transmitted in the logical channel is not transmitted on a carrier other than the carrier associated with the logical channel. The logical channel corresponding to the data packet copied at the PDCP layer may have an association relationship with the carrier. In some scenarios, if the carrier association relationship is not configured, it means that the data transmitted in the logical channel can be transmitted on any carrier.

For example, a parameter can be configured for a logical channel, such as parameter A. The value of parameter A indicates different carriers, indicating that the data transmitted in the logical channel can only be transmitted on the carrier specified by parameter A. For example, parameter A is configured for logical channel 1, parameter A indicates carriers 1 and 2, then it indicates that the data in the logical channel can only be transmitted on parameter carriers 1 and 2. In this way, logical channel 1 and carrier 1 and carrier 2 can be said to have an association relationship, which can also be said to be a binding relationship or a mapping relationship.

6) The duplication of the packet data convergence protocol (packet data convergence protocol, PDCP) layer means that the PDCP entity copies data packets into multiple copies and submits them to different RLC entities respectively, and then transmits them 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, "multiple" means two or more. "And/or" describes the relationship of the related objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, B exists alone, where A, B can be singular or plural. The character "/" generally indicates that the related object is a "or" relationship. "At least one of the following" or a similar expression refers to any combination of these items, including any combination of a single item or a plurality of items. For example, at least one item (a) in a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be a single or multiple .

And, unless stated to the contrary, the embodiments of the present application refer to ordinal numbers such as "first" and "second" to distinguish between multiple objects, and are not used to limit the order, timing, priority, or Importance. For example, the first logical channel and the second logical channel are just to distinguish different logical channels, and do not mean that the priority or importance of the two logical channels are different.

The above describes some concepts involved in the embodiments of the present application, and the technical features involved in the embodiments of the present application are described below.

The duplication of the PDCP layer usually refers to copying the data packets carried by the radio into multiple identical packets (that is, duplicate packets) at the PDCP layer, and then the two data packets are separately delivered to multiple different RLC entities for transmission, and then through Different logical channels are transmitted to the MAC layer. Among them, the logical channel is the channel from the RLC layer to the MAC layer. It should be noted that the retransmission generally refers to retransmission, and the repeated transmission in the embodiments of the present application is not retransmission. Retransmission refers to retransmission after the same data packet fails to be sent, or multiple consecutive transmissions of the same data packet, and repeated transmission is to copy one data packet to two data packets and put them on two logical channels respectively. Here, "repeat" can also be understood as "copy".

In order to ensure the reliability of data transmission, the original packets and duplicate packets transmitted to the MAC layer cannot be transmitted through the same MAC PDU, because only through different MAC PDU transmission, one PDU lost will not affect the transmission of another PDU, equivalent The reliability has doubled.

The following describes how to implement the transmission function of the PDCP layer for the DC scenario and the CA scenario.

Please refer to FIG. 1, which exemplarily shows the network architecture involved in the repetition process of implementing the PDCP layer in the DC scenario. For the base station, the DC scenario involves the primary base station and the secondary base station. The network architecture of the primary base station and the secondary base station for a wireless bearer is shown in FIG. 1, and the network architecture of the terminal device for the wireless bearer includes the one shown in FIG. 1. The network architecture of the primary base station and the network architecture of the secondary base station, that is, the terminal device includes one PDCP entity, two RLC entities, and two MAC entities for the radio bearer. Security, duplication, segment, automatic repeat-request (ARQ), multiplexing (mutiplexing), hybrid automatic repeat-request (HARQ) in Figure 1 ), and robust header compression (ROHC) are all functions that represent PDCP entities, RLC entities, or MAC entities. Among them, the PDCP entity and the PDCP layer can be understood as the same concept. 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 Figure 1 represent the interfaces and/or channels between different layers. The interface is called an inter-layer interface, such as a service access point (service access point, SAP), and the channel may be, for example, a logical channel, which is similar in the following and will not be described in detail. It should be noted that FIG. 1 is only an exemplary framework, and each component in the figure is not an indispensable component of this embodiment. The security module can be omitted as appropriate.

In the DC scenario, a terminal device is connected to two base stations at the same time, that is, the primary base station and the secondary base station. If a radio bearer is configured with the repeat function of the PDCP layer, the two data packets copied at the PDCP layer will be transmitted To two different RLC entities, and transmit to different MAC entities through different logical channels, and finally form two MAC PDUs for transmission on different carriers. This process is the same for both the base station and the terminal equipment. The difference is that for the base station, the PDCP layer in the master base station transmits the copied two data packets to two different RLC entities. These two The RLC entities are respectively located in the primary base station and the secondary base station. After that, 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 secondary base station. MAC entity, these two MAC entities will transmit data packets through their respective carriers. For the terminal device, the two RCL entities and the two MAC entities are located in the terminal device, and other processes are the same.

Please refer to Fig. 2 for the network architecture involved in implementing the repetition 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 a wireless bearer is shown in FIG. 2, that is, the base station and the terminal device for the wireless bearer include a PDCP entity and two RLC entity and two MAC entities. The security, replication, slicing, ARQ, multiplexing, HARQ, and ROHC in FIG. 2 all represent the functions of the PDCP entity, RLC entity, or MAC entity.

In the 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 radio bearer is configured with the repetition function of the PDCP layer, the two copied data packets in the PDCP layer will be transmitted to two different RLC entities, and these two RLC entities will be transmitted to the same through different logical channels. A MAC entity. At this time, because the two data packets are transmitted to the same MAC entity, the MAC entity will transmit the two data packets into a MAC PDU for transmission. Therefore, in order to make the two data packets be transmitted through the two MAC PDUs separately, You can configure a parameter for the logical channel, for example, called parameter A. The value of parameter A is used to indicate different carriers, so as to ensure that these two data packets can eventually form two MAC PDUs to be transmitted on different carriers.

For example, if a parameter A is configured for a logical channel, it means that the data in the RLC entity corresponding to the logical channel can only be transmitted on the carrier indicated by the parameter A. In this way, if the parameter A configured for two logical channels that overlap each other indicates different carriers, then the two data packets that are mutually repeated eventually will be transmitted on different carriers, which can ensure reliability.

In the communication system, the repetition function of the PDCP layer may be configured for the radio bearer, or the repetition function of the PDCP layer configured for the radio bearer may be deactivated. In the CA scenario, when the repetition function of the PDCP layer configured for a radio bearer is deactivated (or, the repetition of the PDCP layer is deactivated), the association relationship between the logical channel and the carrier in the radio bearer is also Will no longer apply. At present, the repetition of the PDCP layer is limited to one radio bearer transmitting data packets copied at the PDCP layer through two logical channels (also commonly known as repeated transmission of two legs). Refer to FIG. 3, assuming that the PDCP layer When the repetition function is activated (or, the repetition of the 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 moment, the repetition function of the PDCP layer is deactivated, and only logical channel 1 is still working. At this time, in order to increase the transmission capacity, the carrier bonding relationship configured for logical channel 1 is no longer applicable, that is, logical channels are allowed. 1 Use all available (active) carriers of the terminal equipment. It can be seen from FIG. 3 that carrier 4 is a carrier that has not previously been associated with any logical channel. If logical channel 1 is allowed to use all active carriers of the terminal device, if carrier 4 is activated, Then logical channel 1 can use carrier 4. The logical channel described here uses a certain carrier, which means that the data transmitted in the logical channel can be transmitted on this carrier.

The communication system may subsequently introduce the duplication of the PDCP layer of multiple logical channels, that is, a radio bearer transmits data packets copied at the PDCP layer through multiple logical channels, for example, it may be transmitted at the PDCP layer through three logical channels. Copy the packet. In this case, if a logical channel is deactivated under the radio bearer, and there may be multiple remaining activated logical channels, how should the carrier corresponding to the logical channel be distributed among the remaining activated logical channels, then Has become an urgent problem to be solved.

For example, a 5G system may repeat the PDCP layer through three logical channels. Refer to FIG. 4, assuming that a certain radio bearer is configured with three logical channels to transmit data packets copied at the PDCP layer (also called three legs). Repeated transmission), the PDCP layer duplicates the data packet in three copies and transmits them in logical channel 1, logical channel 2 and logical channel 3, respectively. The data of logical channel 1 can be transmitted on carrier 1, and the data of logical channel 2 can be Carrier 2 is used for transmission, data of logical channel 3 can be transmitted on carrier 3 to carrier 5, and carrier 6 is a carrier that has not been associated with any logical channel. At a certain moment, logical channel 3 is deactivated. In order to increase the transmission capacity, carrier 3 to carrier 5 can continue to be used. At this time, the activated logical channels include logical channel 1 and logical channel 2. The terminal device cannot determine carrier 3 to Which logical channel should the carrier 5 be associated with?

In view of this, the technical solutions of the embodiments of the present application are provided. In the embodiment of the present application, the wireless bearer transmits the data packet copied at the PDCP layer through at least three logical channels, and the indication information may indicate that the association relationship between the activated logical channel and at least one carrier is set according to the first manner, at least One carrier includes the carrier associated with the deactivated carrier before deactivation, that is to say, for the case that the wireless bearer transmits the data packet copied at the PDCP layer through multiple logical channels, if a logical channel is deactivated, then The embodiment of the present application provides a method for allocating the carrier associated with the deactivated logical channel among the remaining activated logical channels. In other words, when the repetition state of the PDCP layer changes, the embodiments of the present application provide a solution for adjusting the association relationship between the logical channel and the carrier.

The network device is, for example, a base station.

For ease 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 device is a network device and the second communication device is a terminal device as an example. If this embodiment is applied to the network architecture shown in FIG. 5, the network device described below may be the network device in the network architecture shown in FIG. 5, and the terminal device described below may be the network device shown in FIG. 5. Terminal equipment in the network architecture shown. Or, if this embodiment is applied to the network architecture shown in FIG. 6, the network device described below may be the first network device or the second network device in the network architecture shown in FIG. The terminal device mentioned may be the terminal device in the network architecture shown in FIG. 6. In the following introduction, the application of this embodiment to the network architecture shown in FIG. 5 is mainly taken as an example.

S71. The network device determines indication information, where the indication information is used to indicate that an association relationship is set according to a first manner, where the association relationship is a relationship between an activated logical channel and a carrier, where the carrier includes association with a deactivated logical channel Carrier, the activated logical channel and the deactivated logical channel belong to the same radio bearer, and the data packets of the radio bearer are copied into at least three copies, which are respectively transmitted through at least three logical channels;

S72. The terminal device determines to set the association relationship between the activated logical channel and the carrier according to the first manner, where the carrier includes the carrier associated with the deactivated logical channel, the activated logical channel, and the deactivated logical channel Belong to the same wireless bearer, and the data packets of the wireless bearer are copied into at least three copies, and transmitted through at least three logical channels respectively;

S73. The terminal device sets the association relationship between the activated logical channel and the carrier according to the first mode.

The carrier includes the carrier associated with the deactivated logical channel. The carrier associated with the deactivated logical channel herein refers to the 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, it may also be understood as at least one deactivated logical channel. The number of carriers may be one or more, for example, it may be understood as at least one carrier.

The carrier may include only the carrier associated with the deactivated logical channel before deactivation; or, the carrier may include all carriers in the activated state of the terminal device and all carriers in the activated state of the terminal device, It may include all carriers in the activated state associated with the logical channel of the radio bearer, and may also include all carriers in the activated state that are not associated with any logical channel of the radio bearer, where the terminal device is in the activated state All the carriers of, including the carrier associated with the deactivated logical channel before deactivation; or, the carrier may include all other active carriers of the terminal device except the carrier associated with the activated logical channel The carrier in the state, the carrier in the activated state other than the carrier associated with the activated logical channel, may include the carrier associated with the deactivated logical channel before deactivation, and of course This includes all carriers that are not activated and 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 according to the first manner, and there may be different manners of determining. 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. Refer to S74 in FIG. 7 because S74 is not required to be executed, so it is drawn as a dotted line. In addition, if S74 is executed, S74 occurs after S71 and before S72, for example. The first signaling includes indication information, and the indication information indicates that the association relationship between the logical channel and the carrier is set according to the first manner. The first signaling can also be used to configure the repeat function of the radio bearer Or, the first signaling may also be used to activate or deactivate 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 repeat function of the PDCP layer of the radio bearer, that is, the first signaling is also used to configure the repeat transmission function of the PDCP layer of the radio bearer, However, if the network device then instructs to activate or deactivate one or more logical channels of the radio bearer, the network device may not need to send the indication information again, and the terminal device may determine to set the An association relationship between the activated logical channel and the carrier. Alternatively, the association relationship between the activated logical channel and the carrier is set according to the first mode, which may be specified by a protocol, and the terminal device can be determined through the protocol without additional notification from the network device, which helps save transmission overhead In this case, the network device does not need to send instruction information, so S71 does not have to be executed. Wherein, the first signaling is, for example, radio resource control (radio resource control, RRC) signaling, or MAC control element (control element), CE, or downlink control information (downlink control information, DCI), or RLC control PDU, Or PDCP control PDU, etc.

Among them, RLC control PDU (RLC control PDU) refers to a type of RLC PDU that is different from RLC data PDU (RLC data PDU), and is distinguished from RLC data PDU by the indication information in the packet header. Generally, it is used to transfer control information or feedback information of the RLC layer. In the embodiments of the present application, it can be used to transmit control information related to the repetitive function of the PDCP layer, including instructions such as activation/deactivation, and/or carrier association. An indication of relationship.

PDCP control PDU (PDCP control PDU) refers to a type of PDCP PDU that is different from PDCP data PDU (PDCP data PDU), and is distinguished from PDCP data PDU by the indication information in the packet header. Generally, it is used to transfer control information or feedback information of the PDCP layer. In the embodiments of the present application, it can be used to transmit control information related to the repetitive function of the PDCP layer, including instructions such as activation/deactivation, and/or carrier association. An indication of 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 In order to activate one or more logical channels of the radio bearer, both the activated logical channel and the deactivated logical channel indicated by the indication information may be explicit, for example, the network device instructs to deactivate the radio bearer through the first signaling Logical channel 1, and the radio bearer corresponds to logical channel 2 and logical channel 3, then the activated logical channels indicated by the network device through the indication information are logical channel 2 and logical channel 3, and the deactivated logical channel is logical channel 1. The first signaling is also used to activate one or more logical channels of the radio bearer. This may be the case. If the network device configures the PDCP layer repeat function for the radio bearer in advance, all the logic of the radio bearer The channels are all activated. Later, the network device instructs the terminal device to deactivate a part of the logical channel of the radio bearer. After that, the network device instructs the terminal device to activate the logical channel of the radio bearer. Part or all of the deactivated logical channel, then the signaling used by the network device to instruct the terminal device to activate the logical channel of the radio bearer may be the first signaling.

Or, when the network device determines the indication information, it may not yet determine which logical channels of the radio bearer are to be deactivated. For example, the first signaling is a signaling in which the network device configures a repeating function of the PDCP layer for the radio bearer, that is, After the network device sends the first signaling, all logical channels of the radio bearer will be activated. At this time, no logical channels are deactivated. Then, the activated logical channel and the deactivated logical channel indicated by the indication information may be ambiguous, but it is generally referred to as, if there is a deactivated logical channel later, the deactivated logical channel can be used as The deactivated logical channel, and the remaining activated logical channels except the deactivated logical channel can be used as the activated logical channel.

In addition, the data packets carried by the radio are copied into at least three copies at the PDCP layer and transmitted through at least three logical channels, that is to say, the same data packets after being copied are transmitted by at least three logical channels. Among them, each of the at least three logical channels can transmit one data packet, that is, at least three logical channels transmit at least three data packets, and among the at least three data packets, one data packet may be an original data packet The other data packets are the data packets obtained by copying the original data packet. In short, the at least three data packets are collectively referred to as the copied data packet, or the data packet copied at the PDCP layer. The "replicated data packet" or "replicated data packet at the PDCP layer" described later are the same way of understanding.

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

Sub-mode 1. Associate the carrier with the activated logical channel according to the order of the carrier's identification number (ID), wherein one carrier of the carrier and the activated logical channel are connected at a time A logical channel to establish an association relationship; or,

Sub-method 2: Associate the carrier with the activated logical channel in the order of the channel quality of the carrier, wherein one carrier of the carrier and one logic of the activated logical channel are The channel establishes an association relationship; or,

Sub-method 3: Associate the carrier with a logical channel of the activated logical channel; or,

Sub-mode 4. When the number of the activated logical channels is equal to 1, establish an association relationship between the carrier and the activated logical channels; or,

Sub-mode 5. Associate the carrier with the activated logical channel according to the order of the IDs of the corresponding deactivated logical channels, where all the deactivated logical channels are associated before deactivation. The carrier is associated with an activated logical channel; or,

Sub-mode 6. Associate each carrier of the carrier with a logical channel of the activated logical channel in a random manner.

In sub-mode 1, the carrier may be sequentially associated with the logical channel in the order of the ID of the carrier, or may be the carrier in the order of the ID of the carrier and the ID of the logical channel In order of size, an association relationship is sequentially established with the activated logical channel, wherein the carrier with the largest ID can be associated with the logical channel with the largest ID, or the carrier with the largest ID can also be associated with the corresponding ID The smallest logical channel establishes an association relationship. For example, the carrier is carrier 3, carrier 5 and carrier 6, and the activated logical channels are logical channel 1 and logical channel 2, respectively, then sort the carriers according to the order of the carrier ID from large to small, which should be the carrier 6>Carrier 5>Carrier 3, sort the logical channels according to the order of the logical channel ID, from logical channel 2>logical channel 1, according to the order of the carrier ID and the order of the logical channel ID , Sequentially associating the carrier with the activated logical channel. Specifically, carrier 3 can be associated with logical channel 1, carrier 5 can be associated with logical channel 2, and carrier 6 can be associated with logical channel 1 establishes an association relationship, or it may also establish an association relationship between carrier 3 and logical channel 2, an association relationship between carrier 5 and logical channel 1, and an association relationship between carrier 6 and logical channel 2. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the largest carrier ID is associated with the logical channel with the largest logical channel ID first, or the carrier with the smallest carrier ID is first associated with the logical channel with the smallest logical channel ID , No specific restrictions.

It is worth noting that, similar to sub-mode 1, another possible implementation may include one or more of the following steps (for example, may include a and c in the following steps, or include b and c in the following steps , Or include the following steps a, b and c):

a. Sort the carriers according to the size of the carrier ID, and assign new IDs to the sorted carriers starting 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. Sort the activated logical channels according to the size of the logical channel ID, and assign new IDs to the sorted logical channels starting from 0 or 1, for example, the IDs of the sorted logical channels are 0, 1, 2, 3, etc., or 1, 2, 3, etc. respectively.

c. Determine the mapping relationship between the carrier and the activated logical channel.

The method for determining the mapping relationship may be one of the following methods in addition to that described in sub-mode 1:

Modular operation. Specifically, the number N of the activated logical channels is determined, and then the ID and N of the carrier are newly used to perform a modular operation, and the carrier is associated with the corresponding logical channel according to the operation result. For example, if N is 2, then if the result of a modular operation between the ID of a carrier and N is 0, then the carrier will be associated with the new logical channel with ID 0, or if the ID of a carrier is N If the result of the modulo operation is 1, the carrier is associated with the new logical channel with ID 1.

Divide the subset. If the number of the activated logical channels is 2, the carrier is divided into two subsets according to the ID parity of the carrier (the ID that does not need to be renumbered, that is, the original ID of the carrier), and the two subsets and the two logical channels The channel establishes an association relationship, in which a subset is associated with a logical channel; or, the carriers (the IDs that do not need to be renumbered, that is, the original IDs of the carriers) arranged in order according to the size of the carrier ID are divided into the middle The first and second subsets are called the first subset and the second subset, where the first subset refers to the set of IDs before the split point, and the second subset refers to the set of IDs after the split point, The ID of the split point is, for example, an ID with a center value among the IDs of the carriers. The first subset and the second subset are associated with two logical channels, where one subset is associated with one logical channel, and the number of carriers included in the first subset and the second subset may be equal (all The total number of the carriers is an even number), or the number of carriers included in the first and second subsets may not be equal (the total number of the carriers is an odd number).

In sub-mode 2, the carrier may be sequentially associated with the activated logical channel according to the order of the channel quality of the carrier, or may be the carrier according to the order of the channel quality of the carrier, according to The order of the IDs of the logical channels is sequentially associated with the activated logical channel, wherein the carrier with the best channel quality can be associated with the corresponding logical channel with the largest ID, or the carrier with the poorest channel quality An association relationship can be established with the corresponding logical channel with the smallest ID. For example, the carriers are carrier 3, carrier 5 and carrier 6, wherein the channel quality of carrier 3 is better than the channel quality of carrier 6, and the channel quality of carrier 6 is better than the channel quality of carrier 5, the activated logic The channels are logical channel 1 and logical channel 2 respectively, and the logical channels are sorted according to the order of the logical channel ID from large to small, which should be logical channel 2>logical channel 1. Then, according to the order of the channel quality of the carrier and the order of the ID of the logical channel, the carrier is associated with the activated logical channel in sequence. Specifically, the carrier 3 can be associated with the logical channel 1. , Associate carrier 6 with logical channel 2, and associate carrier 5 with logical channel 1, or you can associate carrier 3 with logical channel 2, and associate carrier 6 with logical channel 1, and Associate carrier 5 with logical channel 2. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the best channel quality is first associated with the logical channel with the largest logical channel ID, or the carrier with the poorest channel quality is first associated with the logical channel with the smallest logical channel ID, No specific restrictions. If some logical channel-related carriers have good channel quality and others have poor channel quality, they may not be able to transmit data packets copied at the PDCP layer better, so this application The embodiment proposes to establish an association relationship with the logical channels in order of the channel quality of the carrier, so that the channel quality of the carriers associated with each logical channel does not differ much, and the transmission quality of each logical channel is more balanced to complete better The task of transmitting data packets copied at the PDCP layer. Wherein, the channel quality of the carrier may be measured by the network device, and after measuring the channel quality of the carrier, the network device may send the channel quality of the carrier to the terminal device, for example, the network device may use the first letter Let the channel quality of the carrier be sent to the terminal device, or the network device may also send the channel quality of the carrier to the terminal device through other signaling. In addition, the channel quality of the carrier can also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (for example, the ratio of positive acknowledgement (ACK) received/sent).

In sub-mode 3, the carrier may be associated with one logical channel of the activated logical channel, that is, if there is only one active logical channel, then the carrier’s Each carrier is associated with the one activated logical channel, and if the number of activated logical channels is greater than 1, then each carrier of the carrier can be activated with one of the multiple activated logical channels The logical channel establishes an association relationship. If the number of activated logical channels is greater than 1, then which activated logical channel is selected is not limited in this embodiment of the present application. For example, for a radio bearer, there is generally a primary logical channel, and the remaining logical channels are all secondary logical channels. If the primary logical channel belongs to the activated logical channel, you can choose to connect the carrier to the primary logical channel. Establish an association. For example, a radio bears logical channel 1, logical channel 2, and logical channel 3 for transmitting data packets copied at the PDCP layer, where logical channel 1 is the main logical channel, for example, logical channel 3 is deactivated and logical channel 3 is deactivated Before activation, there is an association relationship with carrier 3, then carrier 3 can be associated with logical channel 1. Of course, you can also choose to associate the carrier with the activated logical channel other than the active logical channel except the main logical channel. Continue to use the above example. If logical channel 3 is deactivated, carrier 3 can be activated. Establish an association relationship with logical channel 1 or logical channel 2. Therefore, it can be considered that the carrier can be associated with any one of the activated logical channels. Wherein, 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 first logical channel may be carried in the first signaling ID, so that the terminal device can determine to associate the carrier with the main logical channel of the activated logical channel, or can also be specified by a protocol without additional instructions from the network device. If the carrier is associated with any one of the activated logical channels, for example, if the carrier is associated with a randomly selected logical channel from the activated logical channels, the network device may Indicated to the terminal device in the first signaling, for example, the ID of the logical channel to which the 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 activated logical channels is equal to 1, the carrier may be associated with this activated logical channel, and when the number of activated logical channels is greater than 1, the The association relationship between the activated logical channel and the carrier does not change, that is, for the activated logical channel, the original association relationship with the carrier is maintained, and the deactivated logical channel is deactivated The carriers associated with each other do not establish an association relationship with the activated logical channel. For example, a radio bearer transmits data packets copied at the PDCP layer through logical channel 1, logical channel 3, and logical channel 3, where logical channel 1 is associated with carrier 1, and logical channel 2 is associated with carrier 2 and carrier 3. Relationship, logical channel 3 and carrier 4 are associated, if both logical channel 2 and logical channel 3 are deactivated, then the number of activated logical channels is 1, then logical channel 2 is associated with carrier 2 before deactivation Both carrier 3 and carrier 4 associated with logical channel 3 before deactivation can be associated with logical channel 1, or if only logical channel 3 is deactivated, the number of activated logical channels is 2 , The association relationship between logical channel 1 and carrier remains unchanged, the association relationship between logical channel 2 and carrier remains unchanged, logical channel 1 is still only associated with carrier 1, logical channel 2 is still only associated with carrier 2 and carrier 3 Associated. This is done to simplify the implementation. For example, if the number of activated logical channels is greater than 1, how to allocate associated carriers to the activated logical channels requires certain rules, which may involve modification of the protocol. In sub-mode 4, if the number of activated logical channels is greater than 1, the association relationship between the logical channels and the carrier may not be changed, so that there is no need to modify the protocol, if the number of activated logical channels is equal to 1, it is sufficient to directly associate the carrier with the activated logical channel, which is relatively simple.

In sub-mode 5, the carrier is sequentially associated with the activated logical channel according to the size order of the ID of the corresponding deactivated logical channel, and the carrier may be deactivated according to the corresponding The order of the IDs of the logical channels, in accordance with the order of the IDs of the activated logical channels, sequentially establishes an association relationship with the activated logical channels, wherein the carrier corresponding to the deactivated logical channel with the largest ID may have the largest ID An association relationship is established between the logical channels of, or a carrier corresponding to the deactivated logical channel with the smallest ID can be associated with the corresponding logical channel with the largest ID. Logical channel 3 and logical channel 4, where carrier 3 is associated with logical channel 3 before deactivation, carrier 4, carrier and carrier 6 are associated with logical channel 4 before deactivation, and the activated logical channels are respectively Logical channel 1 and logical channel 2. Sort the activated logical channels according to the order of the logical channel ID from large to small, which should be logical channel 2> logical channel 1, and sort the deactivated logical channels according to the order of the logical channel ID from large to small , Should be logical channel 4>logical channel 3. Then, according to the order of the IDs of the logical channels, the carrier is associated with the activated logical channel in sequence. Specifically, the carrier 3 associated with the logical channel 3 before deactivation may be associated with the logical channel 1. , Associate the carrier 4, carrier 5, and carrier 6 associated with the logical channel 4 before the deactivation with the logical channel 2, or you can associate the carrier 3 associated with the logical channel 3 before the deactivation with the logical channel 2 Relationship, the carrier 4, carrier 5, and carrier 6 associated with the logical channel 4 before deactivation are associated with the logical channel 1. This method is simpler to implement than sub-methods 1 and 2 that sequentially associate carriers.

In sub-mode 6, each carrier of the carrier may be associated with a logical channel of the activated logical channel in a random manner, that is, the carrier and the activated logical channel are completely randomly established This relationship is relatively simple, without too many rules. Wherein each logical carrier of the carrier is associated with which logical channel of the activated logical channel, the network device may indicate to the terminal device in the first signaling, and the terminal device may determine that each of the carrier The carrier establishes an association relationship with the corresponding logical channel in the activated logical channels.

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

The first way may be as specified in the agreement. Then, if the number of the above-mentioned sub-modes included in the first mode specified in the protocol is greater than 1, it can also indicate to the terminal device which sub-mode is used in conjunction with the signaling of the network device. 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 does not need to carry specific information in the first signaling In the first mode, only the identification information of the first mode can be carried, and the identification information of the first mode can be used as the indication information. For example, the identification information of the first mode is the ID of the first mode. For example, the first mode includes the above sub-mode 2, then the network device may carry the ID of sub-mode 2 in the first signaling, so that the first signaling can indicate that the activated logical channel and the After receiving the first signaling, the terminal device can determine the association relationship between the activated logical channel and the carrier according to sub-mode 2 after receiving the first signaling. This approach helps reduce signaling overhead. However, if the number of 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, then it is possible to indicate to the terminal device without the need for signaling with the network device Which sub-method is used, the terminal device can determine which method is the first method according to the protocol, in this case, the network device does not need to send the first signaling to the terminal device, or, if the first signaling is used for Configure the repetition function of the PDCP layer of the radio bearer, or activate or deactivate one or more logical channels of the radio bearer, then the first signaling only needs to complete the original task, and there is no need to indicate the setting in the first way The association relationship between the activated logical channel and the carrier helps to save signaling overhead. Of course, even if the number of sub-modes included in the first mode specified in the protocol is greater than 1, it may be specified that the terminal device uses these multiple sub-modes 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 there is no restriction on the specific.

Alternatively, the first method may not be prescribed by agreement. Then, the network device may also carry specific first mode information in the first signaling, and the first mode information may be used as the indication information. For example, the first mode includes the above sub-mode 2, the network device may carry the information of sub-mode 2 in the first signaling, so that the first signaling may indicate that the activated logical channel and the After the first signaling is received by the terminal device, the terminal device can determine the association relationship between the activated logical channel and the carrier according to sub-mode 2 according to the information of sub-mode 2, and determine the sub-mode What kind of method is 2? In this way, the terminal device can obtain clearer information.

The first mode may include at least one of the foregoing several sub-modes, and other implementation forms. Or it can be understood that the first mode may include other modes in addition to at least one of the above-mentioned sub-modes.

As an implementation manner of the first mode, the first signaling may also carry a bitmap corresponding to each logical channel of all or part of the activated logical channels, and a bitmap of each logical channel It can be used to indicate the association between each logical channel and carrier. Among them, a bitmap may correspond to an ID of a logical channel, for example, this correspondence may also be carried in the first signaling, so that the terminal device can clarify the correspondence between the bitmap and the logical channel. In other words, the first signaling may carry one or more bitmaps, one of which is used to indicate the association relationship between a logical channel and the carrier, and the logical channel corresponding to the one or more bitmaps is the activated logical channel, which The logical channels corresponding to one or more bitmaps are all or part of the activated logical channels. In this case, the first method may be a method of setting the association relationship between the carrier and the activated logical channel according to the bitmap carried in the first signaling, or the first method is to set the The manner of the association relationship between the carrier and the activated logical channel.

For example, the first signaling is signaling for configuring the repetition function of the PDCP layer of the radio bearer. For example, when configuring the repetition function of the PDCP layer of the radio bearer, the first signaling may be used to carry a bitmap corresponding to each logical channel of all logical channels of the radio bearer, so that the terminal device clarifies each logical channel of the radio bearer Which carriers are associated with each other? In this case, the activated logical channel may be all logical channels of the radio bearer used to transmit data packets copied at 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 instruct to deactivate one or more logical channels of the radio bearer, and the first signaling may also carry all logical channels of the remaining activated logical channels of the radio bearer or each logical channel of a part of logical channels The corresponding bitmap. The remaining activated logical channels may be the remaining activated logical channels after deactivating one or more logical channels of the radio bearer through the first signaling.

For example, there are three logical channels corresponding to the repeat function of the PDCP layer on the radio bearer, namely logical channel 1, logical channel 2 and logical channel 3, of which logical channel 1 is associated with carrier 1 and carrier 2, and logical channel 2 is associated with Carrier 3 has an association relationship, and logical channel 3 has an association relationship with carrier 4 and carrier 5. The network device instructs to deactivate logical channel 3 through the first signaling, then the remaining activated logical channels are logical channel 1 and logical channel 2, then the network device can determine the carrier and logical channel associated with logical channel 3 before deactivation 1 and/or logical channel 2 establishes an association relationship. Specifically, the carrier associated with logical channel 3 before deactivation may be associated with logical channel 1 or logical channel 2, or logical channel 3 before deactivation. The carrier wave of the system is associated with logical channel 1 and logical channel 2. For example, if the network device determines that the carrier 4 associated with logical channel 3 before deactivation is associated with logical channel 1, and the carrier 5 associated with logical channel 3 before deactivation is associated with logical channel 2, then the network device may generate The bitmap corresponding to logical channel 1 and the bitmap corresponding to logical channel 2 are generated. For example, because logical channel 1 to logical channel 3 were originally associated with carrier 1 to carrier 5, then each bitmap can have 5 bits, each bit represents a carrier, and a bitmap from high to low corresponds to carrier 1 to carrier 5 respectively. For which carrier each bit of a bitmap corresponds to, it can be specified in the protocol in advance, or the network device can configure and notify the terminal device in advance. For a bitmap corresponding to a logical channel, if the value of a certain bit is "1", it indicates that the carrier is associated with the logical channel, and if the value of a certain bit is "0", it indicates that it is not Associate the carrier with the logical channel. For example, the two bitmaps generated by the network device are 5 bits, the bitmap corresponding to logical channel 1 is 11010, and the bitmap corresponding to logical channel 2 is 00101, which indicates that logical channel 1 should be established with carrier 1, carrier 2, and carrier 4. Association relationship, and the association relationship between logical channel 2 and carrier 3, carrier 4 and carrier 5, and logical channel 1 is originally associated with carrier 1 and carrier 2, logical channel 2 is originally associated with carrier 3, so The terminal device may determine and then associate the logical channel 1 with the carrier 3, and associate the logical channel 2 with the carrier 4 and the carrier 5.

In the above example, the first signaling carries the bitmap corresponding to all the logical channels of the remaining activated logical channels. In another case, the first signaling may carry the bitmap corresponding to the partial logical channels of the remaining activated logical channels. . For example, for the remaining activated logical channels, there may be some logical channel and carrier relationship does not change, then the first signaling may not carry the bitmap corresponding to these logical channels, but only carry logical channels and carriers The bitmap corresponding to the logical channel whose association relationship has changed. In this way, the signaling overhead can be effectively saved, and the workload of the terminal device can also be reduced. For example, there are three logical channels corresponding to the repeat function of the PDCP layer of the wireless bearer, namely logical channel 1, logical channel 2 and logical channel 3, among which logical channel 1 is associated with carrier 1 and carrier 2, and logical channel 2 is associated with Carrier 3 has an association relationship, logical channel 3 has an association relationship with carrier 4 and carrier 5, the network device instructs to deactivate logical channel 3 through the first signaling, then the remaining activated logical channels are logical channel 1 and logical channel 2, then The network device may determine to associate the carrier associated with logical channel 3 with logical channel 1 and/or logical channel 2 before deactivation. 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 does not change of. Then, the network device can generate a bitmap corresponding to logical channel 2 without generating a bitmap corresponding to logical channel 1. For example, the bitmap has 5 bits, and each bit represents a carrier. The high to low bits correspond to carrier 1 to carrier 5, respectively. The bitmap can be 00111, which means that logical channel 2 should be combined with carrier 3, carrier 4, and The carrier 5 establishes an association relationship, and the logical channel 2 originally has an association relationship with the carrier 3, so the terminal device can determine that the logical channel 2 is associated with the carrier 4 and the carrier 5 again.

Of course, for the remaining activated logical channels, even if the association between some logical channels and the carrier does not change, the first signaling may also carry the bitmap corresponding to these logical channels, that is, if the remaining The association relationship between all logical channels and carriers of the activated logical channels will change, then the first signaling may carry a bitmap corresponding to all the logical channels of the remaining activated logical channels, and if the remaining activated logical channels The association relationship between some logical channels and carriers will not change, so the first signaling may carry a bitmap corresponding to all the logical channels of the remaining activated logical channels, or may also carry some logic of the remaining activated logical channels The bitmap corresponding to the channel is not limited.

For another example, the first signaling is used to indicate one or more logical channels that activate the radio bearer, and the first signaling may also carry all logical channels of the remaining activated logical channels of the radio bearer or each logical channel of the partial logical channels. Bitmap. 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 logics activated through the first signaling channel. If the first signaling is used to indicate activation of one or more logical channels of the radio bearer, then the one or more logical channels may have been deactivated before, and then the one or more logical channels are reactivated, then It will involve a change in the association relationship between the logical channel and the carrier, and the network device may indicate the association relationship between the logical channel and the carrier through a bitmap.

For example, there are three logical channels corresponding to the repeat function of the PDCP layer on the radio bearer, namely logical channel 1, logical channel 2 and logical channel 3, of which logical channel 1 is associated with carrier 1 and carrier 2, and logical channel 2 is associated with Carrier 3 has an association relationship, and logical channel 3 has an association relationship with carrier 4 and carrier 5. The network device previously deactivated logical channel 3, after deactivating logical channel 3, the associated carrier 4 of logical channel 3 before deactivation established an association relationship with logical channel 1, and carrier 5 associated with logical channel 2 . After that, the network device instructs 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. Then, the network device can redistribute the association between the logical channel and the carrier relationship. For example, the network device may restore the original association relationship between the logical channel and the carrier, that is, establish the association relationship between the logical channel 1 and the carrier 1 and the carrier 2, establish the association relationship between the logical channel 2 and the carrier 3, and Channel 3 is associated with carrier 4 and carrier 5. Then the network device can carry 3 bitmaps in the first signaling, which correspond to logical channel 1 to logical channel 3, for example, each bitmap has 5 bits, each bit represents a carrier, and one bitmap corresponds from high bit to low bit.于carrier1～carrier5. For example, the bitmap corresponding to logical channel 1 is 11000, the bitmap corresponding to logical channel 2 is 00100, and the bitmap corresponding to logical channel 3 is 00011. The terminal device can determine how to establish the relationship between the logical channel and the carrier according to these 3 bitmaps connection relation. Of course, restoring the original association relationship is just an example, and the network device may redistribute the association relationship between the logical channel and the carrier without considering the original association relationship, for example, the network device may establish carrier 1 and logical channel 3 Association relationship, etc.

In the above example, the first signaling carries the bitmap corresponding to all the logical channels of the remaining activated logical channels. In another case, the first signaling may carry the bitmap corresponding to the partial logical channels of the remaining activated logical channels. . For example, for the remaining activated logical channels, there may be some logical channel and carrier relationship does not change, then the first signaling may not carry the bitmap corresponding to these logical channels, but only carry logical channels and carriers The bitmap corresponding to the logical channel whose association relationship has changed. In this way, the signaling overhead can be effectively saved, and the workload of the terminal device can also be reduced.

For example, there are three logical channels corresponding to the repeat function of the PDCP layer on the radio bearer, namely logical channel 1, logical channel 2 and logical channel 3, of which logical channel 1 is associated with carrier 1 and carrier 2, and logical channel 2 is associated with Carrier 3 has an association relationship, and logical channel 3 has an association relationship with carrier 4 and carrier 5. The network device previously deactivated logical channel 3, after deactivating logical channel 3, the associated carrier 4 of logical channel 3 before deactivation established an association relationship with logical channel 1, and carrier 5 associated with logical channel 2 . After that, the network device instructs 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. Then, the network device can redistribute the association between the logical channel and the carrier relationship. For example, the network device determines to establish an association relationship between logical channel 3 and 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 carrier will not Changes. Then the network device can carry 2 bitmaps in the first signaling, corresponding to logical channel 1 and logical channel 3, for example, each bitmap has 5 bits, each bit represents a carrier, and one bitmap corresponds from high to low于carrier1～carrier5. For example, the bitmap corresponding to logical channel 1 is 01010, and the bitmap corresponding to 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 two bitmaps. It can be seen that for logical channel 2, the network device may not need to carry the corresponding bitmap in the first signaling, thereby helping to save signaling overhead.

Or, if the previous signaling is used to indicate activation of one or more logical channels of the radio bearer, the indication information included in the first signaling may also be used to indicate restoration of the original association between the logical channel of the radio bearer and the carrier The relationship, the so-called original relationship, is the relationship between all logical channels and carriers before the one or more logical channels are deactivated. In this way, the first signaling does not need to carry a bitmap.

For example, there are three logical channels corresponding to the repeat function of the PDCP layer on the radio bearer, namely logical channel 1, logical channel 2 and logical channel 3, of which logical channel 1 is associated with carrier 1 and carrier 2, and logical channel 2 is associated with Carrier 3 has an association relationship, and logical channel 3 has an association relationship with carrier 4 and carrier 5. The network device previously deactivated logical channel 3, after deactivating logical channel 3, the associated carrier 4 of logical channel 3 before deactivation established an association relationship with logical channel 1, and carrier 5 associated with logical channel 2 . After that, the network device instructs 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. Then, the network device can redistribute the association between the logical channel and the carrier relationship. For example, the network device may restore the original association relationship between the logical channel and the carrier, that is, establish the association relationship between the logical channel 1 and the carrier 1 and the carrier 2, establish the association relationship between the logical channel 2 and the carrier 3, and Channel 3 is associated with carrier 4 and carrier 5. Then the network device only needs to carry the indication information, for example, the indication information can occupy 1 bit. If the value of this bit is "1", it indicates that the original association relationship is restored. If the value of this bit is 1 "0" means that the original association is not restored. Taking the value of this 1 bit as "1" as an example, the terminal device may determine to restore the original association relationship, that is, establish the association relationship between logical channel 1 and carrier 1 and carrier 2, and establish logical channel 2 and carrier 3 The association relationship, and the association relationship between the logical channel 3 and the carrier 4 and the carrier 5 is established. After the logical channel is deactivated and activated again, the original association relationship can be restored through simple indication information, without setting too many rules, and the implementation is relatively simple.

The first signaling as described above indicates the association relationship between the logical channel and the carrier by carrying a bitmap. The indication method is relatively clear and simple, and is convenient for the terminal device to set according to the indication information. In addition, in the method described above, the first signaling carries the bitmap. In another case, the network device may also send second signaling to the terminal device. The second signaling may be used to indicate activation or deactivation of the radio bearer. One or more logical channels, the second signaling may carry a bitmap bitmap corresponding to each logical channel of all or part of the remaining logical channels of the wireless bearer, and the bitmap of each logical channel is used to indicate each logical channel Channel and carrier association. In other words, the second signaling carries one or more bitmaps, one of which is used to indicate the association relationship between a logical channel and the carrier, and the logical channel corresponding to the one or more bitmaps is the remaining activated logical channel of the radio bearer, The remaining activated logical channel is the remaining activated logical channel after deactivating one or more logical channels of the radio bearer according to the second signaling. In this case, the first method may be a method of setting the association relationship between the carrier and the activated logical channel according to a bitmap carried by other signaling, or it may be understood that the first method is based on the setting of the bitmap The manner of the association relationship between the carrier and the activated logical channel. If the second signaling is used to indicate activation of one or more logical channels of the radio bearer, the remaining activated logical channels are the remaining ones after activation of the one or more logical channels of the radio bearer according to the second signaling The activated logical channel, or, if the second signaling is used to indicate the deactivation of one or more logical channels of the radio bearer, the remaining activated logical channels deactivate the radio bearer according to the second signaling Activated logical channel remaining after one or more logical channels. 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 a signaling for configuring a repeat function of the PDCP layer of the radio bearer, and the second signaling may be used for activating or deactivating after configuring the repeat function of the PDCP layer of the radio bearer Signaling of one or more logical channels of the radio bearer. Of course, the specific implementation manners of the first signaling and the second signaling are not limited in the embodiments of the present application. However, if the bitmap is carried by the second signaling, the implementation of the bitmap, etc., can refer to the introduction to the bitmap carried by the first signaling in the foregoing. Whether the bitmap is carried through the first signaling or the second signaling depends on the specific implementation manner of the network device, or may also be stipulated by a protocol, and the specific is not limited.

In addition, in addition to the implementation form of the first manner described above, the first manner may have other implementation forms. In other words, in addition to the modes described above, the first mode may also include one of the following several embodiments or any combination thereof.

As an implementation manner, the first manner may be a manner of disassociating the first logical channel from 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 relationship between the first logical channel and the first carrier. For example, for the first logical channel, there is an association relationship with multiple carriers, and the channel quality of the first carrier is poor, and the first carrier has little effect on the transmission of data packets copied at the PDCP layer. Therefore, the network device may instruct 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 to indicate activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining activated logic after activating the one or more logical channels Channel, and if the first signaling is used to indicate the deactivation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining ones after deactivating the one or more logical channels Active logical channel.

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

As another implementation manner, the first 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 the second carrier Move 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 relationship between the first logical channel and the second carrier , And establish an association relationship between the second carrier and the second logical channel. For example, the first logical channel has an association relationship with multiple carriers, and the channel quality of the multiple carriers are all good, but the channel quality of the carrier having an association relationship with the second logical channel may not be very good, then the network device It can instruct 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, so as to associate the carrier with a better channel quality for the second logical channel to improve the The transmission quality of the data packets copied by the PDCP layer. Wherein, if the first signaling is used to indicate activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining activated logic after activating the one or more logical channels Channel, and if the first signaling is used to indicate the deactivation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining ones after deactivating the one or more logical channels Active logical channel.

Of course, in this embodiment, it is not limited to moving only one carrier, and the carriers can be processed in batches. For example, the association relationship between the first logical channel and multiple carriers can be released, and each carrier and multiple carriers can be established. The association relationship between one or more logical channels, or the association relationship between multiple logical channels and the corresponding carrier, and the association relationship between the carrier and the one or more logical channels that establish the disassociation relationship, etc. Wait.

As yet another embodiment, the first method may also be a method of establishing an association relationship between a first logical channel and a third carrier, where the third carrier is in a state where no association relationship is established with all logical channels of the radio bearer For the carrier in the activated state, the first logical channel is one of the remaining activated logical channels. That is, the third carrier has not previously established an association relationship with any logical channel of the radio bearer, and the network device may indicate the association relationship between the third carrier and the first logical channel through the indication information. For example, the channel quality of the carrier that has an association relationship with the first logical channel may not be very good, and the channel quality of the third carrier is good, then the network device may instruct to associate the third carrier with the first logical channel, thereby improving The transmission quality of the data packets copied at the PDCP layer. Wherein, if the first signaling is used to indicate activation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining activated logic after activating the one or more logical channels Channel, and if the first signaling is used to indicate the deactivation of one or more logical channels of the radio bearer, the remaining activated logical channels may be the remaining ones after deactivating the one or more logical channels Active logical channel.

Of course, in this embodiment, it is not limited to moving only one carrier, and the carriers can also be processed in batches. For example, the association relationship between the first logical channel and multiple carriers can be established, and multiple carriers are not connected to the radio bearer. All the logical channels of the associated carriers are in the active state, and so on.

There is another implementation manner. The first manner may be a manner of establishing an association relationship between the first logical channel and the fourth carrier, the fourth carrier is the carrier indicated by the indication information, and the first logical channel is the activated logical channel one of. For example, if the network device instructs to activate the first logical channel through the first signaling, the network device may indicate the carrier that needs to be associated with the first logical channel through the indication information. The carrier that needs to be associated with the first logical channel may be a Or more, for example, the indication information may include the IDs of these carriers, so that after receiving the first signaling, the terminal device may determine to activate the first logical channel, and associate the carrier corresponding to the ID of the carrier included in the indication information with the first Logical channels establish associations. The fourth carrier is any carrier that needs to be associated with the first logical channel. The carrier that needs to be associated with the first logical channel may include at least one carrier that currently has an associated relationship with other activated logical channels and a carrier that does not have an associated relationship with any logical channel. The carrier that establishes the association relationship of a logical channel includes the carrier that currently has an association relationship with other activated logical channels. After receiving the first signaling, the terminal device needs to release the association relationship between these carriers and the previously established logical channel, and then Associate these carriers with the first logical channel, and if the carriers that need to be associated with the first logical channel include carriers that are not associated with any logical channel, the terminal device directly establishes these after receiving the first signaling The association relationship between the carrier and the first logical channel is sufficient.

As mentioned above, various implementation forms of the first mode are introduced. As to which one is adopted in the first mode, it can be specified by a protocol or configured by a network device in advance.

For example, if the logical channel of a radio bearer used to transmit data packets copied at the PDCP layer is originally a first logical channel and a second logical channel, and then the network device instructs to activate the third logical channel, the wireless bearer The logical channel used to transmit the data packet copied at the PDCP layer becomes the first logical channel, the second logical channel, and the third logical channel. For example, the network device activates the third logical channel through the first signaling instruction. 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 between the three logical channels and the carrier , So that the terminal device can associate the carrier with the corresponding logical channel according to the 3 bitmaps. Of course, if there is no change in the association relationship between the logical channel and the carrier in the first logical channel and the second logical channel, the network device may not carry the bitmap of the logical channel that has not changed in the first signaling, thereby The signaling overhead is saved, and the step of processing the first signaling by the terminal device is also reduced.

Or, if the logical channel of a radio bearer used to transmit the data packet copied at the PDCP layer is originally a first logical channel and a second logical channel, and then the network device instructs to activate the third logical channel, the wireless bearer uses The logical channel used to transmit the data packet copied at the PDCP layer becomes the first logical channel, the second logical channel, and the third logical channel. For example, the network device activates the third logical channel through the first signaling instruction. The included indication information may indicate that the association relationship between the activated logical channel and the carrier is set according to the first mode, then the terminal device may also set the association relationship between the activated logical channel and the carrier according to the first mode, where the first The mode includes, for example, at least one of sub-mode 1, sub-mode 2, sub-mode 3, sub-mode 4, sub-mode 5, or sub-mode 6 as described above.

Or, if the logical channel of a radio bearer used to transmit the data packet copied at the PDCP layer is originally a second logical channel and a third logical channel, and then the network device instructs to activate the first logical channel again, the radio bearer uses The logical channel for transmitting the data packet copied at the PDCP layer becomes the first logical channel, the second logical channel, and the third logical channel. For example, the network device uses the first signaling instruction to activate the first logical channel. The indication information included in the first signaling may include the ID of one carrier or the IDs of multiple carriers. The carrier corresponding to the ID of the carrier included in the indication information is required. Carriers that establish an association relationship with the first logical channel, then after receiving the first signaling, the terminal device may establish an association relationship between these carriers and the first logical channel.

In the embodiment of the present application, the wireless bearer transmits the data packet copied at the PDCP layer through at least three logical channels, and the indication information may indicate that the association relationship between the activated logical channel and at least one carrier is set according to the first manner, at least One carrier includes the carrier associated with the deactivated carrier before deactivation, that is to say, for the case that the wireless bearer transmits the data packet copied at the PDCP layer through multiple logical channels, if a logical channel is deactivated, then The embodiment of the present application provides a method for allocating the carrier associated with the deactivated logical channel among the remaining activated logical channels. And the first method can be various, more flexible.

In the embodiment shown in FIG. 7, the wireless bearer transmits the data packet copied at the PDCP layer through at least three logical channels, and it is also possible that the wireless bearer will continue to transmit the data copied at the PDCP layer through two logical channels. package. In the case where the radio bearer transmits the data packet copied at the PDCP layer through two logical channels, if according to the prior art, the two logical channels corresponding to the radio bearer are configured in advance, and are generally configured after the configuration No change can be made, so no matter whether the transmission quality of the configured logical channel is better or worse, it is still necessary to continue to transmit the data packet copied at the PDCP layer through the previously configured logical channel. Such a method is likely to result in poor transmission quality of the copied data packet at the PDCP layer. In view of this, the embodiments of the present application provide a second method for configuring a logical channel. In this method, the logical channel corresponding to the radio bearer used to transmit the data packet copied at the PDCP layer can be flexibly changed, thereby improving the PDCP The transmission quality of the data packets copied by the layer.

Please refer to Fig. 8 for a flowchart of the method. In the following introduction process, 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 devices, such as a third communication device and a fourth communication device, where the third communication device may be a network device or a network device capable of supporting the functions required by the method The communication device or the third communication device may be a terminal device or a communication device capable of supporting the function required by the method by the terminal device, and of course, may be other communication devices, such as a chip system. The same is true for the fourth communication device. The fourth communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the fourth communication device may be a terminal device or a device capable of supporting the terminal device to implement the method. Of course, the communication device with the required function can also be other communication devices, such as a chip system. Moreover, there are no restrictions on the implementation manners of the third communication device and the fourth communication device, for example, the third communication device may be a network device, the fourth communication device is a terminal device, or the third communication device and the fourth communication device are both networks The device, or the third communication device and the fourth communication device are both terminal devices, or the third communication device is a network device, and the fourth communication device is a communication device capable of supporting the functions required by the method by the terminal device, and so on. The network device is, for example, a base station.

For ease of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the third communication device is a network device and the fourth communication device is a terminal device as an example. If this embodiment is applied to the network architecture shown in FIG. 5, the network device described below may be the network device in the network architecture shown in FIG. 5, and the terminal device described below may be the network device shown in FIG. 5. Terminal equipment in the network architecture shown.

The terminal device mentioned may be the terminal device in the network architecture shown in FIG. 6. In the following introduction, the application of this embodiment to the network architecture shown in FIG. 5 is mainly taken as an example.

S81. The network device determines to configure at least three logical channels for the wireless bearer of the terminal device;

S82. The network device sends first indication information to the terminal device. The terminal device receives the first indication information from the network device. The first indication information is used to indicate that the wireless bearer passes the at least three logical channels. The first logical channel and the second logical channel are transmitted, wherein the data packet carried by the radio is copied into two and transmitted through the first logical channel and the second logical channel, respectively;

S83. The terminal device determines that the wireless bearer is transmitted through the first logical channel and the second logical channel of at least three logical channels according to the first indication information, where the data packet of the wireless bearer is copied Divided into two, respectively transmitted through the first logical channel and the second logical channel.

In the embodiment of the present application, the network device may configure at least three logical channels for the repetitive function of the PDCP layer of the radio bearer, and at one moment, the network device may indicate that the two logical channels are transmitted on the PDCP layer through the first indication information The copied data packet, then the first indication information may be information that the network device originally used to select the logical channel used to transmit the data packet copied at the PDCP layer, that is, the first logical channel and the second logical channel are network devices The logical channel initially selected after configuring at least three logical channels, or the first indication information may also be information that the network device subsequently changes the logical channel, that is, the first logical channel and the second logical channel are the logic that the network device initially selects The logical channel that is changed after the channel, 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 through the first indication information. It can be seen that, through the technical solution provided by the embodiments of the present application, the logical channel used to transmit the data packet copied at the PDCP layer can be flexibly changed, so that a logical channel with better communication quality can be selected to transmit the copy at the PDCP layer Data packets to improve transmission quality.

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

In addition, the network device may send configuration information to the terminal device in addition to the at least three logical channels configured to transmit the data packet copied at the PDCP layer for the radio bearer, and the configuration information is used to indicate the radio bearer After configuring the at least three logical channels, after receiving the configuration information from the network device, the terminal device can determine that the at least three logical channels are configured for the radio bearer. Among them, the configuration information and the first indication information can be carried in a signaling, for example, the signaling is used to activate the repetition function of the PDCP layer, that is, the signaling can complete several functions, one is for The radio bearer is configured with at least three logical channels, the other is used to activate the repetition function of the PDCP layer of the radio bearer, and the other is used to indicate that transmission through the first logical channel and the second logical channel is replicated at the PDCP layer data pack. Alternatively, the configuration information and the first indication information may also be carried in different signaling, for example, the configuration information is carried in the signaling for activating the repetition function of the PDCP layer, and the first indication information is carried in the activation or deactivation. Activate signaling of a logical channel used to transmit data packets copied at the PDCP layer. Wherein, a logical channel used to activate a data packet that is copied at the PDCP layer refers to that the network device previously instructed to deactivate the logical channel, then the logical channel can be instructed to be activated again for deactivation. A logical channel that transmits data packets copied at the PDCP layer means that the network device previously instructed to activate the logical channel (for example, it may be activated when the repeated transmission function is activated, or activated after deactivation), then Subsequent instructions can be made to deactivate the logical channel again.

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

In addition, in the case where the wireless bearer transmits the data packet copied at the PDCP layer through two logical channels, if according to the prior art, each logical channel of the wireless bearer used to transmit the data packet copied at the PDCP layer is specific Which carriers are associated with it is also pre-configured and generally cannot change after configuration, so no matter whether the configured carrier has good or poor transmission quality, it still needs to continue to be transmitted through the pre-configured carrier at the PDCP layer. Copy the packet. This method is also likely to result in poor transmission quality of the data packets copied 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 to set 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, which may be determined in different ways, wherein the carrier Including a carrier associated with the deactivated logical channel before deactivation, the deactivated logical channel being a deactivated logical channel except the one or two activated logical channels among the at least three logical channels . For example, the network device determines second indication information, and the second indication information is used to instruct the terminal device to set 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, And the network device sends the second indication information to the terminal device, and after receiving the second indication information, the terminal device can determine to set one or two activated logical channels of the first logical channel and the second logical channel according to the first mode and the Association relationship between carriers. For example, if the first logical channel and the second logical channel of the second logical channel are deactivated and the first logical channel is the activated logical channel, then the carrier includes the carrier associated with the second logical channel 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 (that is, the first logical channel or the second logical channel, or the first logical channel A logical channel and a second logical channel), depending on the activation states of the first logical channel and the second logical channel. In addition, among the at least three logical channels, all logical channels except the first logical channel and the second logical channel can be regarded as deactivated logical channels, for example, the network device indicates that the first logical channel The channel and the second logical channel transmit the data packet copied at the PDCP layer, which can be regarded as a logical channel other than the first logical channel and the second logical channel in which at least three logical channels are deactivated. When the network device configures at least three logical channels, it can also configure the carrier associated with each logical channel of the at least three logical channels. Then, the network device is other than the first logical channel and the second logical channel. The associated carriers configured by the logical channels are the carriers associated with these logical channels before deactivation.

That is to say, the second indication information can be used to flexibly indicate the association between the activated logical channel and the carrier. The carrier configured for the logical channel is not static, and the network device can flexibly indicate the change, so that it can be changed according to the specific situation. The carrier wave associated with the logical channel helps to improve the transmission quality.

Alternatively, 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 the first manner, which may be specified by a protocol, for example, a specific In one way, the terminal device can be determined through the protocol without additional notification from the network device, which helps to save transmission overhead.

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

When determining the second indication information, the network device may have determined which logical channel of the first logical channel and the second logical channel is to be deactivated, for example, signaling carrying the second indication information is also used to deactivate the first logical channel or The second logical channel, or the first signaling is also 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, such as the network The device also instructs to deactivate the first logical channel of the radio bearer through signaling carrying the second indication information, then one or two activated logical channels indicated by the network device through the second indication information is the second logical channel, and deactivates The logical channel is the first logical channel.

Or, when the network device determines the second indication information, it may not yet determine which logical channel of the first logical channel and the second logical channel is to be deactivated. For example, the signaling that carries the second indication information is that the network device is the wireless The signaling that carries the repetition function of the PDCP layer, that is, after the network device sends the signaling that carries the second indication information, both the first logical channel and the second logical channel will be activated, and there is no deactivated logic at this time. channel. Then, the activated logical channel or the deactivated logical channel indicated by the second indication information may be ambiguous, but it is generally referred to as, if there is a deactivated logical channel later, the deactivated logical channel is It can be used as the deactivated logical channel, and the remaining activated logical channels except the deactivated logical channel can be used as the activated logical channel.

The configuration information, the first indication information, and the second indication information may be carried in one signaling and sent, for example, the signaling is used to activate the repetition function of the PDCP layer, that is, the signaling may complete several Function, the first is to configure at least three logical channels for the radio bearer, the second is to repeat the PDCP layer of the radio bearer function, the third is used to indicate the first logical channel and the second logic The channel transmits the data packet copied at the PDCP layer, and the fourth is to indicate the association relationship between one or two activated logical channels and the carrier that set the first logical channel and the second logical channel in the first manner. Alternatively, the configuration information, the first indication information, and the second indication information may also be carried in different signalings, where the three pieces of information may be carried in three different signalings, or the three pieces of information, respectively. Part of the information can be carried in one signaling, and the remaining information in the three messages can be carried in another signaling. For example, the configuration information is carried in the signaling used to activate the repetition function of the PDCP layer, and the first indication information and the second indication information are carried in a logic used to activate or deactivate the data packet copied at the PDCP layer. In the signaling of the channel, or, the configuration information and the first indication information are carried in the signaling used to activate the repetition function of the PDCP layer, and the second indication information is carried in the PDCP layer for activation or deactivation for transmission. The signaling of a logical channel of the copied data packet, or the configuration information is carried in the signaling for activating the repetition function of the PDCP layer, and the first indication information is carried in the signaling for activating the transmission for being replicated in the PDCP layer In signaling of a logical channel of a data packet, the second indication information is carried in signaling for deactivating a logical channel for transmitting a data packet copied at the PDCP layer, and so on.

Sub-method 1. Associate the carrier with one or two activated logical channels according to the order of the carrier's identification number (ID), wherein one carrier of the carrier and the one or One logical channel of two activated logical channels establishes an association relationship; or,

Sub-method 2: Associate the carrier with the one or two activated logical channels in the order of the channel quality of the carrier, wherein one carrier of the carrier is associated with the one or two at a time A logical channel of an activated logical channel establishes an association relationship; or,

Sub-mode 3. Associate the carrier with one of the one or two activated logical channels; or,

Sub-mode 4. When the number of the one or two activated logical channels is equal to 1, establish an association relationship between the carrier and the activated logical channel; or,

Sub-mode 5. Associate the carrier with the one or two activated logical channels according to the order of the IDs of the corresponding deactivated logical channels, where one deactivated logical channel before deactivation All associated carriers are associated with an activated logical channel; or,

Sub-mode 6. Associate each carrier of the carrier with a logical channel of the one or two activated logical channels in a random manner; or,

Sub-mode 7. The second indication information includes a first index. The first mode is a mode corresponding to the first index. The first index is used to indicate the association relationship between the logical channel and the carrier. Wherein, the first logical channel and the second logical channel 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, and the first index belongs to at least two indexes.

In sub-mode 1, the carrier may be sequentially associated with the one or two activated logical channels according to the size order of the carrier ID, or may be the carrier according to the size order of the carrier ID The sequence of the IDs of the logical channels is sequentially associated with the one or two activated logical channels, wherein the carrier with the largest ID can be associated with the logical channel with the largest ID, or the corresponding ID The largest carrier may also be associated with the corresponding logical channel with the smallest ID. For example, the carriers are carrier 3, carrier 5 and carrier 6, and the activated logical channels are the first logical channel and the second logical channel, then the carriers are sorted according to the order of the carrier ID from large to small, which should be Carrier 6>Carrier 5>Carrier 3, the logical channels are sorted according to the order of the logical channel ID from large to small, which should be the second logical channel>the first logical channel, according to the order of the carrier ID and the logical channel ID The order of the size is to sequentially associate the carrier with the one or two activated logical channels. Specifically, carrier 3 may be associated with the first logical channel, and carrier 5 may be associated with the second logical channel. Relationship between carrier 6 and the first logical channel, or carrier 3 can be associated with the second logical channel, carrier 5 can be associated with the first logical channel 1, and carrier 6 can be associated with the first logical channel Two logical channels establish an association relationship. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the largest carrier ID is associated with the logical channel with the largest logical channel ID first, or the carrier with the smallest carrier ID is first associated with the logical channel with the smallest logical channel ID , No specific restrictions.

b. Sort the one or two activated logical channels according to the size of the logical channel ID, and assign new IDs to the sorted logical channels in sequence starting from 0 or 1, such as the IDs of the sorted logical channels 0, 1, etc., or 1, 2, etc., respectively.

c. Determine the mapping relationship between the carrier and the one or two activated logical channels.

Modular operation. Specifically, determine the number N of the one or two activated logical channels (N is a positive integer less than or equal to 2), and then perform a modular operation with the newly-programmed ID of the carrier and N, and associate the carrier to The corresponding logical channel. For example, if N is 2, then if the result of a modular operation between the ID of a carrier and N is 0, then the carrier will be associated with the new logical channel with ID 0, or if the ID of a carrier is N If the result of the modulo operation is 1, the carrier is associated with the new logical channel with ID 1.

In sub-mode 2, the carrier may be sequentially associated with the one or two activated logical channels according to the order of the channel quality of the carrier, which may be the preference of the carrier according to the channel quality of the carrier Inferior order, according to the order of the ID of the logical channel, establish an association with the one or two activated logical channels in sequence, wherein the carrier with the best channel quality can establish an association with the corresponding logical channel with the largest ID, or The carrier with the worst channel quality can also be associated with the corresponding logical channel with the smallest ID. For example, the carriers are Carrier 3, Carrier 5 and Carrier 6, wherein the channel quality of Carrier 3 is better than the channel quality of Carrier 6, and the channel quality of Carrier 6 is better than the channel quality of Carrier 5, the activated logic The channels are the first logical channel and the second logical channel, and the logical channels are sorted according to the order of the IDs of the logical channels from large to small, which should be second logical channel>first logical channel. Then, according to the order of the channel quality of the carrier and the order of the ID of the logical channel, the carrier is associated with the activated logical channel in sequence. Specifically, carrier 3 may be associated with the first logical channel Relationship, the carrier 6 is associated with the second logical channel, and the carrier 5 is associated with the first logical channel, or the carrier 3 can be associated with the second logical channel, and the carrier 6 can be associated with the first logical channel Establish an association relationship, and establish an association relationship between the carrier 5 and the second logical channel. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the best channel quality is first associated with the logical channel with the largest logical channel ID, or the carrier with the poorest channel quality is first associated with the logical channel with the smallest logical channel ID, No specific restrictions. If some logical channel-related carriers have good channel quality, and others have poor channel quality, they may not be able to transmit data packets replicated at the PDCP layer. The example proposes to establish an association relationship with the logical channels in order of the channel quality of the carrier, so that the channel quality of the carriers associated with each logical channel does not differ much, and the transmission quality of each logical channel is more balanced to complete the transmission better The function of the data packet copied at the PDCP layer. Wherein, the channel quality of the carrier may be measured by a network device, and after measuring the channel quality of the carrier, the network device may send the channel quality of the carrier to the terminal device, for example, the network device may carry the second The signaling of the indication information sends the channel quality of the carrier to the terminal device, or the network device may also send the channel quality of the carrier to the terminal device through other signaling. In addition, the channel quality of the carrier can also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (for example, the ratio of positive acknowledgement (ACK) received/sent).

In submode 3, the carrier may be associated with one of the one or two activated logical channels, that is, if the number of the one or two activated logical channels is only One, then each carrier of the carrier can be associated with the one activated logical channel, and if the number of one or two activated logical channels is 2, then each carrier of the carrier can be Each carrier is 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, then which activated logical channel is selected is not limited in this 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 may be selected to establish an association relationship with the primary logical channel. 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 the main logical channel, and the first logical channel and the second logical channel are transmitted through the PDCP layer. The data packet, for example, the data packet carried by the radio is copied into two at the PDCP layer, and transmitted through the first logical channel and the second logical channel respectively. These two data packets are the data packets copied at the PDCP layer, and the first Both a logical channel and a second logical channel are active logical channels. For example, the third logical channel has an association relationship with carrier 3, then carrier 3 may be associated with the first logical channel. Of course, you can also choose to associate the carrier with the activated logical channels of the one or two activated logical channels other than the main logical channel, and continue to use the above example. You can use carrier 3 and the second logic The channel establishes an association relationship. Therefore, it can be considered that the carrier can be associated with any one of the one or two activated logical channels. Wherein, 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 second indication information, for example, the second indication information may include the main logical channel’s ID, so that the terminal device can determine to associate the carrier with the main logical channel of the one or two activated logical channels, or can also be specified by a protocol without additional instructions from the network device. If the carrier is associated with any one of the one or two activated logical channels, for example, a randomly selected one of the carrier and the one or two activated logical channels The logical channel establishes an association relationship, then the network device may indicate to the terminal device in the second indication information. For example, the second indication information may carry the ID of the logical channel to be established, so that the terminal device can determine the carrier to The logical channel establishes an association relationship.

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 one or two activated logical channels When the number is 2, the association relationship between the one or two activated logical channels and the carrier does not change, that is, for the one or two activated logical channels, the original Relationship. 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 the main logical channel, and the first logical channel and the second logical channel are transmitted through the PDCP layer. The data packet, for example, the data packet carried by the radio is copied into two at 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 activated logical channels, 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 the third logical channel has an association relationship with carrier 4. If the second logical channel is deactivated, then the one Or the number of two activated logical channels is 1, then the carrier 2 and carrier 3 associated with the second logical channel before deactivation and the carrier 4 associated with the third logical channel before deactivation can be the same as the first The logical channel establishes an association relationship, or, if the first logical channel or the second logical channel are both activated logical channels, then the number of the one or two activated logical channels is 2, then the first logical channel and the carrier The association relationship between the two is unchanged, and the association relationship between the second logical channel and the carrier is also unchanged. The first logical channel is still only associated with carrier 1, and the second logical channel is still only associated with carrier 2 and carrier 3. This is done to simplify the implementation. For example, if the number of the one or two activated logical channels is 2, how to allocate associated carriers to the one or two activated logical channels requires certain rules. It may involve modifying the protocol, so in sub-mode 4, if 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 may not be changed In this way, there is no need to modify the protocol. If the number of the one or two activated logical channels is equal to 1, it is sufficient to directly associate the carrier with this activated logical channel, which is relatively simple.

In sub-mode 5, the carrier is sequentially associated with the one or two activated logical channels according to the order of the IDs of the corresponding deactivated logical channels. The carrier may be correlated according to the corresponding The order of the IDs of the deactivated logical channels is, in accordance with the order of the IDs of the activated logical channels, to establish an association with the one or two activated logical channels in sequence, where the deactivated logical channel with the largest ID corresponds to The carrier of may be associated with the corresponding logical channel with the largest ID, or the carrier corresponding to the deactivated logical channel with the smallest ID may be associated with the logical channel with the largest ID. The deactivated logical channel here may include at least three logical channels other than the first logical channel and the second logical channel, and if the first logical channel or the second logical channel is deactivated, Then, the deactivated logical channel may further include the deactivated logical channel in the first logical channel and the second logical channel. For example, a radio bearer is configured with a first logical channel, a second logical channel, a third logical channel and a fourth logical channel, and the data packets copied at the PDCP layer are transmitted through the first logical channel and the second logical channel, for example , The data packet carried by the radio is copied into two at the PDCP layer, respectively transmitted through the first logical channel and the second logical channel, and the first logical channel and the second logical channel are both activated logical channels, wherein the first logical The 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. Sort the one or two activated logical channels according to the order of the logical channel ID from large to small, which should be the second logical channel> the first logical channel, and sort the logical channels according to the order of the logical channel ID from large to small The order of the deactivated logical channels should be fourth logical channel>third logical channel. Then, according to the order 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 can be associated with the first An association relationship is established between a logical channel, and the carrier 5 and carrier 6 associated with the fourth logical channel before deactivation are associated with the second logical channel, or the carrier 4 associated with the third logical channel before deactivation can be established An association relationship is established with the second logical channel, and the carrier 5 and carrier 6 associated with the fourth logical channel before deactivation are associated with the first logical channel. This method is simpler to implement than sub-methods 1 and 2 that sequentially associate carriers.

In sub-mode 6, each carrier of the carrier may be associated with one of the one or two activated logical channels in a random manner, that is, the carrier and the one are completely randomly established Or the association relationship between two activated logical channels, this implementation is relatively simple, without too many rules. Wherein each logical carrier of the carrier is associated with which one 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 transfer the Each carrier of the carrier is associated with the corresponding logical channel of the one or two activated logical channels.

In 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, at least two indexes include index 1 and index 2. The association relationship between the logical channel and the carrier corresponding to index 1 is that the first logical channel has an association relationship with carrier 1 and carrier 2, and the second logical channel and carrier 3 have Association relationship, and the association relationship between the logical channel and carrier corresponding to index 2 is that the first logical channel has association relationship with carrier 1 and carrier 3, and the second logical channel has association relationship with carrier 2, as can be seen, different indexes The corresponding relationship between the corresponding logical channel and the carrier is different. Then, the terminal device can determine the carrier associated with the first logical channel and the carrier associated with the second logical channel according to the first index. If the second indication information includes the corresponding index, the terminal device naturally knows how to set the The carrier associated with a logical channel and the carrier associated with a second logical channel. For example, when the repeat function of the PDCP layer of the radio bearer is activated, the first logical channel has an association relationship with carrier 1, the second logical channel has an association relationship with carrier 3, and subsequent network devices include the first through the second indication information. Index, 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 carrier 1 and carrier 2, and the second logical channel has an association relationship with carrier 3, then the terminal device can also Carrier 2 establishes an association relationship with the first logical channel.

The first method may be specified in the protocol. Then, if the number of sub-modes included in the first method specified in the protocol is greater than 1, you can also use the signaling of the network device to indicate to the terminal device which one to use. Or which sub-methods. 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 mode, the network device need not carry specific information in the second indication information. The first mode information may only carry the identification information of the first mode, 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 the ID of the first mode. For example, the first mode includes the above sub-mode 2, the network device may carry the ID of sub-mode 2 in the second indication information, so that the second indication information may indicate that the one or two activated logics are set according to the first mode The association relationship between the channel and the carrier. After receiving the second indication information, the terminal device can determine, according to the ID of sub-mode 2, that one or two activated logical channels and the carrier are set according to sub-mode 2. Relationship. This approach helps reduce signaling overhead. However, if the number of 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, then it is possible to indicate to the terminal device without the need for signaling with the network device Which sub-mode is used, the terminal device can determine which mode is the first mode according to the protocol, in this case, the network device does not need to send the second indication information to the terminal device, for example, signaling carrying the second indication information Is to configure the repeat function of the PDCP layer of the radio bearer, or to activate or deactivate one or two logical channels of the radio bearer, then the signaling carrying the second indication information only needs to complete the original task, There is no need to carry second indication information, which helps to save signaling overhead. Of course, even if the number of sub-modes included in the first mode specified in the protocol is greater than 1, it may be specified that the terminal device uses these multiple sub-modes to set 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 there is no restriction.

Alternatively, the first mode may not be specified by the protocol, then the network device may also carry the specific first mode information in the second indication information. For example, the first mode includes the above sub-mode 2, the network device may carry the information of sub-mode 2 in the second indication information, so that the second indication information may indicate that the one or two activated logics are set according to the first mode The association relationship between the channel and the carrier. After receiving the second indication information, the terminal device can determine, according to the information of sub-mode 2, that one or two activated logical channels and the carrier are set according to sub-mode 2. The relationship between them, and what kind of sub-method 2 is exactly. In this way, the terminal device can obtain clearer information.

As an implementation manner of the first manner, the second indication information may also carry a bitmap corresponding to the first logical channel and/or a bitmap corresponding to the second logical channel (that is, carry a bitmap or corresponding to the first logical channel Bitmap corresponding to the second logical channel, or bitmap corresponding to the first logical channel and bitmap corresponding to the second logical channel), the bitmap of the first logical channel is used to indicate the association relationship between the first logical channel and the carrier, the second The bitmap of the logical channel is used to indicate the association relationship between the second logical channel and the carrier. Among them, a bitmap may correspond to an ID of a logical channel, for example, this correspondence may also be carried in the second indication information, so that the terminal device can clarify the correspondence between the bitmap and the logical channel. In this case, the first method may be a method of setting the association relationship between the carrier and the one or two activated logical channels according to the bitmap included in the second indication information, or the first method is based on bitmap sets the manner of the association relationship between the carrier and the one or two activated logical channels.

For example, the signaling carrying the second indication information is signaling for configuring the repetition function of the PDCP layer of the radio bearer. For example, when configuring the repetition function of the PDCP layer of the radio bearer, the signaling may be used to carry second indication information, that is, a bitmap corresponding to each logical channel of the first logical channel and the second logical channel of the radio bearer, It makes the terminal equipment know exactly which carriers the first logical channel and the second logical channel respectively have an associated relationship with.

Alternatively, 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 the deactivation of the first logical channel, then the second indication information may carry the bitmap corresponding to the second logical channel. Or for example, the signaling carrying the second indication information is used to indicate the activation of the first logical channel, then the second indication information may carry the bitmap corresponding to the first logical channel and/or the bitmap corresponding to the second logical channel. Specifically, if the signaling carrying the second indication information is used to indicate the activation of the first logical channel, then the second indication information may carry the bitmap corresponding to the first logical channel, and the association relationship between the second logical channel and the carrier may be It may or may not change. If the association relationship between the second logical channel and the carrier changes, the second indication information may carry the bitmap corresponding to the second logical channel, and if the second logical channel and the carrier Does not change, the second indication information may carry the bitmap corresponding to the second logical channel to make the indication clearer, or may not carry the bitmap corresponding to the second logical channel, thereby reducing signaling overhead.

Or, if the previous signaling is used to indicate the activation of the first logical channel, the second indication information may also be used to indicate the restoration of the original association relationship between the first logical channel and the carrier, the so-called original association relationship, That is, before the first logical channel is deactivated, the association relationship between the first logical channel and the carrier. Since only the data packets copied at the PDCP layer are transmitted through the first logical channel and the second logical channel, the second indication information can also be regarded as an indication to restore the original association relationship between the first logical channel and the carrier, and restore The original association relationship between the second logical channel and the carrier. In this manner, the second indication information may not include bitmap.

For example, a radio bearer is configured with a first logical channel, a second logical channel, and a third logical channel, and the data packets copied at the PDCP layer are transmitted through the first logical channel and the second logical channel. For example, the radio bearer The data packet is copied into two at the PDCP layer and transmitted through the first logical channel and the second logical channel respectively, where the first logical channel has an association relationship with carrier 1 and the second logical channel has association relationships with carrier 2 and carrier 3, The third logical channel has an association relationship with the carrier 4. After indicating that the data packet copied at the PDCP layer is transmitted through the first logical channel and the second logical channel through the first indication information, the first logical channel is instructed to deactivate. After a logical channel is deactivated, for example, carrier 1 is associated with the second logical channel. After that, the network device instructs to activate the first logical channel through signaling carrying the second indication information, then the second indication information may indicate to restore the original association relationship between the first logical channel and the carrier, and the terminal device receives the second indication information After that, the association relationship between carrier 1 and the first logical channel may be established again, and the association relationship is restored to that the first logical channel has an association relationship with carrier 1, and the second logical channel has association relationships with carrier 2 and carrier 3. For example, the second indication information can occupy 1 bit. If the value of this 1 bit is "1", it means that the original association relationship is restored. If the value of this 1 bit is "0", it means no. Restore the original association. After the logical channel is deactivated and activated again, the original association relationship can be restored through a simple second indication information, without setting too many rules, and the implementation is relatively simple.

The second indication information described above indicates the association relationship between the logical channel and the carrier by including a bitmap. The indication method is relatively clear and simple, and is convenient for the terminal device to set according to the indication information. In addition, in the manner described above, the second indication information includes a bitmap. In another case, the network device may also send third indication information to the terminal device. The signaling carrying the third indication information may be used to indicate activation or deactivation. 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 the first logical channel The association relationship with the carrier, the bitmap of the second logical channel is used to indicate the association relationship between the second logical channel and the carrier. In this case, the first method may be a method of setting the 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 method is A manner of setting the association relationship between the carrier and the one or two activated logical channels according to a bitmap. In this case, the network device does not send the bitmap to the terminal device through the second indication information, but sends the 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 a bitmap, the implementation of the bitmap, etc., can refer to the previous introduction to the second indication information including the bitmap. Whether the bitmap is included in the second indication information or the third indication information depends on the specific implementation of the network device, or it can also be stipulated in the protocol without specific restrictions.

The configuration information, the first indication information, the second indication information, and the third indication information may be carried in one signaling, for example, the signaling is used to activate the repetition function of the PDCP layer, that is, the signaling Several functions can be completed, the first is to configure at least three logical channels for the radio bearer, the second is to repeat the function of the PDCP layer of the radio bearer, and the third is to indicate that the first logic is passed The channel and the second logical channel transmit the data packet copied at the PDCP layer, and the fourth is to indicate the association between one or two activated logical channels and the carrier that set the first logical channel and the second logical channel in the first manner relationship. Alternatively, the configuration information, the first indication information, the second indication information, and the third indication information may also be carried in different signalings, where the four pieces of information may be carried in four different signalings, respectively, or Part of the four pieces of information can be carried in one signaling, and the remaining information in the four pieces of information can be carried in another signaling. For example, the configuration information is carried in the signaling used to activate the repetition function of the PDCP layer, and the first indication information, the second indication information, and the third indication information are carried in the activation or deactivation for transmission copied at the PDCP layer. The signaling of one logical channel of the data packet, or, the configuration information and the first indication information are carried in the signaling for activating the repetition function of the PDCP layer, and the second indication information and the third indication information are carried in the activation Or deactivate the signaling used to transmit a logical channel of the data packet copied at the PDCP layer, or the configuration information is carried in the signaling used to activate the repeat function of the PDCP layer, the first indication information and the second indication The information is carried in the signaling for activating a logical channel for transmitting the data packet copied at the PDCP layer, and the third indication information is carried in the logic for deactivating the logical channel for transmitting the data packet copied at the PDCP layer Channel signaling, etc.

As an implementation manner, the first manner may be a manner of disassociating the first logical channel from the first carrier, and the first logical channel may be an activated 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 relationship between the first logical channel and the first carrier. For example, for the first logical channel, there is an association relationship with multiple carriers, and the channel quality of the first carrier is poor, and the first carrier has little effect on the transmission of data packets copied at the PDCP layer. Therefore, the network device may instruct to release the association relationship between the first logical channel and the first carrier through the second indication information.

Or for this embodiment, it can also be understood that the first manner may be a manner of releasing the association relationship between at least one logical channel and the corresponding carrier, and the at least one logical channel may be the first logical channel and/or the second logical channel (That is, the first logical channel or the second logical channel, or the first logical channel and the second logical channel), for each logical channel of at least one logical channel, the corresponding carrier may refer to the logical channel associated with All or part of the carrier. For example, the first method may be a method of releasing the association relationship between the first logical channel and carrier 1, and a method of releasing the association relationship between the second logical channel and carrier 2.

As another implementation manner, the first 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 the second carrier Move from the first logical channel to the second logical channel. The first logical channel and the second logical channel may be activated logical channels. In this way, 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 connection between the first logical channel and the second carrier The association relationship, and the establishment of the association relationship between the second carrier and the second logical channel. For example, the first logical channel has an association relationship with multiple carriers, and the channel quality of the multiple carriers is all good, but the channel quality of the carrier having an association relationship with the second logical channel may not be very good, then the network device It can instruct to disassociate the first logical channel and the second carrier, and establish the association between the second carrier and the second logical channel, thereby associating a carrier with a better channel quality for the second logical channel to improve transmission the quality of.

Of course, in this embodiment, it is not limited to moving only one carrier, and the carriers can be processed in batches. For example, the association relationship between the first logical channel and multiple carriers can be released, and each carrier and multiple carriers can be established. The association relationship between one or more logical channels, or the association relationship between the first logical channel and the corresponding carrier can be released to establish the association relationship between the carrier disassociated from the first logical channel and the second logical channel , And, disassociate the second logical channel from the corresponding carrier, establish the association between the carrier disassociated from the second logical channel and the first logical channel, and so on.

As still another embodiment, the first method may also be a method of establishing an association relationship between the first logical channel and the third carrier, and the third carrier is in a state where the association relationship between the first logical channel and the second logical channel is not established. The carrier in the activated state, or the third carrier is the carrier in the activated state that has not been associated with at least three logical channels of the radio bearer. That is, the third carrier has not previously established an association relationship with any logical channel of the radio bearer, or has not established an association relationship with the first logical channel and the second logical channel, and the network device may indicate that the third The carrier wave establishes an association relationship with the first logical channel. For example, the channel quality of the carrier that has an association relationship with the first logical channel may not be very good, and the channel quality of the third carrier is good, then the network device may instruct to associate the third carrier with the first logical channel, thereby improving Transmission quality.

Of course, in this embodiment, it is not limited to moving only one carrier, and the carriers can also be processed in batches. For example, the association relationship between the first logical channel and multiple carriers can be established. The carrier in the active state where the channel is associated with the second logical channel, or all carriers in the active state that are not associated with at least three logical channels of the radio bearer, and so on.

In the embodiment of the present application, the network device may configure at least three logical channels for the repetitive function of the PDCP layer of the radio bearer, and at a moment, the network device may indicate that the two logical channels are transmitted on the PDCP layer through the first indication information The copied data packet, for example, the data packet carried by the radio is copied into two at the PDCP layer and transmitted through two logical channels respectively, then the first indication information may be that the network device was originally used to select for transmission at the PDCP layer The information of the logical channel of the copied data packet, that is, the first logical channel and the second logical channel are the logical channels originally selected by the network device after configuring at least three logical channels, or the first indication information may also be the follow-up of the network device Information about changing logical channels, that is, the first logical channel and the second logical channel are logical channels that are changed after the network device initially selects the logical channel, for example, the initially selected logical channel may be the first logical channel and the third logical channel , And then change to the first logical channel and the second logical channel through the first indication information. It can be seen that, through the technical solution provided by the embodiments of the present application, the logical channel used to transmit the data packet copied at the PDCP layer can be flexibly changed, so that a logical channel with better communication quality can be selected to transmit the copy at the PDCP layer Data packets to improve transmission quality.

As mentioned above, in the case where the wireless bearer transmits the data packet copied at the PDCP layer through two logical channels, if according to the prior art, the logical channel used by the wireless bearer to transmit the data packet copied at the PDCP layer Which carriers are associated with are configured in advance, and generally cannot be changed after configuration, so no matter whether the transmission quality of the configured carrier is good or poor, it is still necessary to continue to transmit through the pre-configured carrier at the PDCP layer. Copy the packet. This way 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 this method, the carrier associated with the logical channel can be flexibly changed, thereby improving transmission quality.

Please refer to Fig. 9 for a flowchart of the method. In the following introduction process, 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 devices, such as a fifth communication device and a sixth communication device, where the fifth communication device may be a network device or a network device capable of supporting the functions required by the method The communication device or the fifth communication device may be a terminal device or a communication device capable of supporting the functions required by the method by the terminal device, and of course, may be other communication devices, such as a chip system. The same is true for the sixth communication device. The sixth communication device may be a network device or a communication device capable of supporting the network device to realize the functions required by the method, or the sixth communication device may be a terminal device or a device capable of supporting the terminal device to implement the method. Of course, the communication device with the required function can also be other communication devices, such as a chip system. And there is no restriction on the implementation manner of the fifth communication device and the sixth communication device, for example, the fifth communication device may be a network device, the sixth communication device is a terminal device, or the fifth communication device and the sixth communication device are both networks The device, or the fifth communication device and the sixth communication device are both terminal devices, or the fifth communication device is a network device, and the sixth communication device is a communication device capable of supporting the functions required by the method by the terminal device, and so on. The network device is, for example, a base station.

For ease of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the fifth communication device is a network device and the sixth communication device is a terminal device as an example. If this embodiment is applied to the network architecture shown in FIG. 5, the network device described below may be the network device in the network architecture shown in FIG. 5, and the terminal device described below may be the network device shown in FIG. 5. Terminal equipment in the network architecture shown. Or, if this embodiment is applied to the network architecture shown in FIG. 6, the network device described below may be the first network device or the second network device in the network architecture shown in FIG. The terminal device mentioned may be the terminal device in the network architecture shown in FIG. 6. In the following introduction, the application of this embodiment to the network architecture shown in FIG. 5 is mainly taken as an example.

S91. The network device determines adjustment information. The adjustment information is used to adjust a carrier associated with at least one logical channel. The at least one logical channel is configured for a wireless bearer of the terminal device, and the data packet of the wireless bearer is copied into At least one copy, respectively transmitted through the at least one logical channel;

S92. The network device sends first signaling to the terminal device. The terminal device receives the first signaling from the network device. The first signaling includes the adjustment information. The first signaling is except RRC. Signalling other than signaling;

S93. The terminal device adjusts the carrier associated with the at least one logical channel according to the adjustment information.

Other signaling besides RRC signaling, such as MAC, CE, DCI, RLC control PDU or PDCP control PDU, etc., does not specifically limit.

In the embodiment of the present application, the network device may instruct to adjust the carrier associated with at least one logical channel through first signaling, and the first signaling is not RRC signaling, so that the network device may dynamically adjust the relationship between the logical channel and the carrier The association relationship can be, for example, logical channels as much as possible to associate carriers with better channel quality to improve transmission quality. Moreover, in the prior art, if the association 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 the relationship between the logical channel and the carrier of the new radio bearer. The association relationship is different from the original radio bearer. However, in the embodiment of the present application, the network device changes the association relationship between the logical channel and the carrier while maintaining the original radio bearer. There is no need to create a new radio bearer. Bring the processing flow.

The first signaling is, for example, signaling for activating the repetition function of the PDCP layer of the radio bearer, or may also be signaling for activating or deactivating the first logical channel or the second logical channel of the radio bearer, specifically There are no restrictions. The first logical channel and the second logical channel are logical channels configured for the radio bearer to transmit data packets copied at the PDCP layer, and the at least one logical channel belongs to the first logical channel and the second logical channel, For example, at least one logical channel includes a first logical channel and/or a second logical channel (that is, a first logical channel or a second logical channel, or a first logical channel and a second logical channel).

In the embodiment of the present application, the adjustment information is used to instruct adjustment of the carrier associated with at least one logical channel, and there may be multiple indication manners of the adjustment information.

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

For example, before the network device sends the adjustment information, 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, for example, the channel quality of carrier 1 is poor, while the carrier 2 and carrier 3 The channel quality is good. The network device may instruct to change carrier 2 or 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 carrier 3. Then the terminal device can be released. The association relationship between carrier 2 and the second logical channel and the association relationship between carrier 2 and the first logical channel are established, so that the adjusted carrier associated with the second logical channel is 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 adjustment is associated with the first logical channel Carrier is carrier 1 and carrier 3, and the adjusted carrier associated with the second logical channel is carrier 4, then the terminal device can disassociate carrier 2 from the first logical channel, and remove carrier 3 from the second logical channel The association relationship and the association relationship between the carrier 3 and the first logical channel are established, 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 at least one logical channel, and each carrier of the carrier to be adjusted is a logic of one of the two logical channels The channels have an association relationship. The two logical channels are configured for radio bearers. The two logical channels are used to transmit data packets that are copied at the PDCP layer. For example, the data packets of the radio bearer are copied into two copies and pass through the two The logical channels are transmitted, 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 can adjust according to the carrier currently associated with each logical channel of the at least one logical channel and the information of the carrier to be adjusted corresponding to each logical channel of the at least one logical channel indicated by the adjustment information. Carrier associated with at least one logical channel. For example, the terminal device may release the association relationship between the carrier to be adjusted and the original logical channel, and establish the association relationship between the carrier to be adjusted and the other logical channel of the two logical channels, or the terminal device may also just The association relationship between the carrier to be adjusted and the original logical channel is released, and the association relationship between the carrier to be adjusted and the other logical channel of the two logical channels is not established. How to deal with the terminal device can be through a protocol Specified or configured by network equipment.

For example, before the network device sends the adjustment information, 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, for example, the channel quality of carrier 1 is poor, while the carrier 2 and carrier 3 The channel quality is good. The network device may instruct to change carrier 2 or carrier 3 to be associated with the first logical channel. For example, if the adjustment information indicates carrier 3, then the terminal device may disassociate carrier 3 from the second logical channel. And the association relationship between the carrier 3 and the first logical channel is established. Or for example, before the network device sends the adjustment information, the first logical channel is associated with carrier 1, and the second logical channel is associated with carrier 2 and carrier 3. For example, if the channel quality of carrier 3 is poor, the adjustment information may indicate Carrier 3, then the terminal device can disassociate the carrier 3 from 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 does not have an association relationship with two logical channels and an adjustment mode, where the adjustment mode is used to set at least one logical channel and the carrier to be adjusted The relationship between the two logical channels is configured for radio bearers. The two logical channels are used to transmit data packets copied at the PDCP layer, and the two logical channels include at least one logical channel. The two logical channels are the first One logical channel and the second logical channel. After receiving the adjustment information, the terminal device can set the association relationship between at least one logical channel and the carrier to be adjusted according to the adjustment mode 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 mode may include one of the following sub-modes or any combination thereof:

Sub-method 1. Associate the carrier to be adjusted with at least one logical channel according to the order of the carrier ID, wherein each time one carrier of the carrier to be adjusted is associated with one logical channel of at least one logical channel ;or,

Sub-mode 2: Associate the carrier to be adjusted with at least one logical channel according to the channel quality order of the carrier, wherein one carrier of the carrier to be adjusted and one logical channel of at least one logical channel are established each time Association; or,

Sub-mode 3: Associate the carrier to be adjusted with one logical channel of at least one logical channel; or,

Sub-mode 4. When the number of at least one logical channel is equal to 1, establish an association relationship between the carrier to be adjusted and the logical channel; or,

Sub-mode 5. Associate each carrier of at least one carrier with one logical channel of at least one logical channel in a random manner; or,

Sub-mode 6. The adjustment information includes a first index. The first mode is a mode corresponding to the first index. The first index is used to indicate the association relationship between the logical channel and the carrier.

In sub-mode 1, the carrier to be adjusted may be sequentially associated with at least one activated logical channel according to the order of the carrier ID, or may be to be adjusted according to the order of the carrier ID The order of the size of the IDs is sequentially associated with at least one activated logical channel, where the carrier with the largest ID can be associated with the logical channel with the largest ID, or the carrier with the largest ID can also be associated with The logical channel with the smallest ID establishes an association relationship. For example, the carriers to be adjusted are carrier 3, carrier 5 and carrier 6, and at least one activated logical channel is the first logical channel and the second logical channel. Then, sort the carriers according to the order of the carrier ID from large to small. Carrier 6>Carrier 5>Carrier 3, the logical channels are sorted according to the order of the logical channel ID from large to small, it should be the second logical channel>first logical channel, according to the order of the carrier ID size, and the logical channel In the order of the size of the ID, the carrier to be adjusted is sequentially associated with at least one activated logical channel. Specifically, carrier 3 can be associated with the first logical channel, and carrier 5 can be associated with the second logical channel. And associating the carrier 6 with the first logical channel, or alternatively, associating the carrier 3 with the second logical channel, associating the carrier 5 with the first logical channel 1, and associating the carrier 6 with the second logical channel The channel establishes an association relationship. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the largest carrier ID is associated with the logical channel with the largest logical channel ID first, or the carrier with the smallest carrier ID is first associated with the logical channel with the smallest logical channel ID , No specific restrictions.

a. Sort the carriers to be adjusted according to the size of the carrier ID, and assign new IDs to the sorted carriers starting from 0 or 1 again. For example, the IDs of the sorted carriers are 0, 1, 2, 3, respectively. Etc., or 1, 2, 3 etc. respectively.

b. Sort at least one logical channel according to the size of the ID of the logical channel, and assign 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. Determine the mapping relationship between the carrier to be adjusted and at least one logical channel.

Modular operation. Specifically, determine the number N of at least one logical channel (N is a positive integer less than or equal to 2), and then perform a modular operation with the newly-programmed ID of the carrier and N, and associate the carrier to be adjusted to the corresponding logical channel according to the operation result . For example, if N is 2, then if the result of a modular operation between the ID of a carrier and N is 0, then the carrier will be associated with the new logical channel with ID 0, or if the ID of a carrier is N If the result of the modulo operation is 1, the carrier is associated with the new logical channel with ID 1.

Divide the subset. If the number of at least one logical channel is 2, the carrier to be adjusted is divided into two subsets according to the ID parity of the carrier (the ID that does not need to be renumbered, that is, the original ID of the carrier), and the two subsets and the two logical channels are divided Establish an association relationship, in which a subset is associated with a logical channel; or, the carriers (the IDs that do not need to be renumbered, that is, the original IDs of the carriers) arranged in order according to the size of the carrier ID are divided into the middle and back Two subsets, such as the first and second subsets, where the first subset refers to the set of IDs before the split point, and the second subset refers to the set of IDs after the split point. The ID of the dot is, for example, an ID with a center value among the IDs of the carrier waves. Associate the first and second subsets with two logical channels, where one subset is associated with one logical channel, and the number of carriers included in the first and second subsets may be equal (to be The total number of adjusted carriers is even), or the number of carriers included in the first and second subsets may not be equal (the total number of carriers to be adjusted is odd).

In sub-mode 2, the carrier to be adjusted may be sequentially associated with at least one activated logical channel according to the order of the channel quality of the carrier, which may be the carrier to be adjusted according to the order of the channel quality of the carrier , According to the order of the ID of the logical channel, in order to establish an association relationship with at least one activated logical channel, wherein the carrier with the best channel quality can be associated with the corresponding logical channel with the largest ID, or the channel with the worst channel quality The carrier may also be associated with the corresponding logical channel with the smallest ID. For example, the carriers to be adjusted are carrier 3, carrier 5 and carrier 6, wherein the channel quality of carrier 3 is better than the channel quality of carrier 6, and the channel quality of carrier 6 is better than the channel quality of carrier 5, at least one activated The logical channels are the first logical channel and the second logical channel, and the logical channels are sorted according to the order of the IDs of the logical channels from large to small, which should be the second logical channel>the first logical channel. Then, according to the order of the channel quality of the carrier and the order of the ID of the logical channel, the carrier to be adjusted is associated with at least one activated logical channel in sequence. Specifically, carrier 3 can be established with the first logical channel Association relationship, the association relationship between carrier 6 and the second logical channel, and the association relationship between carrier 5 and the first logical channel, or the association relationship between carrier 3 and the second logical channel, and the association between carrier 6 and the first logical channel The channel establishes an association relationship, and associates the carrier 5 with the second logical channel. Among them, multiple carriers can be associated with corresponding logical channels at the same time, or multiple carriers can be associated with corresponding logical channels in a time-sharing manner. If multiple carriers are associated with corresponding logical channels in a time-sharing manner Relationship, it may be that the carrier with the best channel quality is first associated with the logical channel with the largest logical channel ID, or the carrier with the poorest channel quality is first associated with the logical channel with the smallest logical channel ID, No specific restrictions. If some logical channel-related carriers have good channel quality, and others have poor channel quality, they may not be able to transmit data packets replicated at the PDCP layer. The example proposes to establish an association relationship with the logical channels in order of the channel quality of the carrier, so that the channel quality of the carriers associated with each logical channel does not differ much, and the transmission quality of each logical channel is more balanced to complete the transmission better The function of the data packet copied at the PDCP layer. The channel quality of the carrier may be measured by a network device, and after the network device measures the channel quality of the carrier, the channel quality of the carrier may be sent to the terminal device, for example, the network device may carry adjustment information Signaling sends the channel quality of the carrier to the terminal device, or the network device may also send the channel quality of the carrier to the terminal device through other signaling. In addition, the channel quality of the carrier can also be determined by the terminal device or the network device according to the success rate of data transmission on a certain carrier (for example, the ratio of positive acknowledgement (ACK) received/sent).

In sub-mode 3, the carrier to be adjusted can be associated with one activated logical channel of at least one activated logical channel, that is, if there is only one number of the at least one activated logical channel, then Associate each carrier to be adjusted with the one activated logical channel, and if the number of at least one activated logical channel is 2, that is, the activated logical channels are the first logical channel and the second logical channel , Then each of the carriers to be adjusted can be associated with one of the two activated logical channels. If the number of at least one activated logical channel is 2, that is, both the first logical channel and the second logical channel are activated logical channels, then which activated logical channel is selected is not limited in this 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 may be selected to establish an association relationship with the primary logical channel. For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit data packets copied at the PDCP layer. For example, the data packets of the radio bearer are duplicated at the PDCP layer and pass through the first logical channel respectively And the second logical channel, the first logical channel is the main logical channel, and the first logical channel and the second logical channel are both active logical channels, for example, carrier 3 has not been associated with the first logical channel and the second logical channel before Relationship, then the carrier 3 may be associated with the first logical channel. Of course, you can also choose to associate the carrier to be adjusted with the activated logical channels other than the main logical channel of the at least one activated logical channel. To continue using the above example, you can connect carrier 3 to the second logical channel Establish an association. Therefore, it can be considered that the carrier to be adjusted can be associated with any one of the activated logical channels of the at least one activated logical channel. Wherein, if the carrier to be adjusted is associated with the main logical channel of at least one activated logical channel, the network device may indicate to the terminal device in the adjustment information, for example, the adjustment information may include the ID of the main logical channel, thereby The terminal device may determine to establish an association relationship between the carrier to be adjusted and the main logical channel of the at least one activated logical channel, or may also be specified by a protocol without additional instructions from the network device. If the carrier to be adjusted is associated with any one of the activated logical channels of the at least one activated logical channel, for example, the carrier to be adjusted is associated with a logical channel randomly selected from the at least one activated logical channel, then The network device may indicate to the terminal device in the adjustment information. For example, the adjustment information may carry the ID of the logical channel to which the association relationship needs to be established, so that the terminal device may determine that the carrier to be adjusted is associated with the logical channel.

In sub-mode 4, when the number of at least one activated logical channel is equal to 1, the carrier to be adjusted can be associated with the activated logical channel, and when the number of at least one activated logical channel is 2, at least The association relationship between an activated logical channel and the carrier does not change, that is, for at least one activated logical channel, the original association relationship with the carrier is maintained. For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit data packets copied at the PDCP layer, the first logical channel is the main logical channel, and both the first logical channel and the second logical channel are active Logical channel, wherein 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 the first logical channel and the second logical channel. If the second logical channel is deactivated, then the number of at least one activated logical channel is 1, then the carrier 4 may be associated with the first logical channel, or, if both the first logical channel and the second logical channel are activated Logical channel, then the number of at least one activated logical channel is 2, the association relationship between the first logical channel and the carrier remains unchanged, and the association relationship between the second logical channel and the carrier remains unchanged, and the first logical channel remains It is only associated with carrier 1, the second logical channel is still only associated with carrier 2 and carrier 3, and carrier 4 is still not associated 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 how to allocate associated carriers to the one or two activated logical channels requires certain rules, which may involve modification Protocol, so in sub-mode 4, if the number of the one or two activated logical channels is 2, the association relationship between at least one activated logical channel and the carrier may not be changed, so that there is no need to modify the protocol, if If the number of at least one activated logical channel is equal to 1, it is sufficient to directly associate the carrier to be adjusted with this activated logical channel, which is relatively simple.

In sub-mode 5, each carrier of the carrier to be adjusted may be associated with one logical channel of at least one activated logical channel in a random manner, that is, the carrier to be adjusted and the at least one activated logic are completely randomly established The association relationship between channels is relatively simple, and does not require too many rules. Wherein each logical carrier of the carrier to be adjusted is associated with which logical channel of the at least one activated logical channel, the network device may indicate to the terminal device in the adjustment information, and the terminal device may determine each of the carrier to be adjusted The carrier establishes an association relationship with a logical channel corresponding to at least one activated logical channel. For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit data packets copied at the PDCP layer, the first logical channel is the main logical channel, and both the first logical channel and the second logical channel are active Logical channel, wherein 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 the first logical channel and the second logical channel. The network device indicates carrier 4 in the adjustment information, indicates that the adjustment mode is sub-mode 5, and indicates the ID of the first logical channel, then the terminal device can determine that the carrier 4 is associated with the first logical channel.

In 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, at least two indexes include index 1 and index 2. The association relationship between the logical channel and carrier corresponding to index 1 is that the first logical channel has an association relationship with carrier 1 and carrier 2, and the second logical channel and carrier 3 have Association relationship, and the association relationship between the logical channel and the carrier corresponding to index 2 is that the first logical channel has an association relationship with carrier 1 and carrier 3, and the second logical channel has an association relationship with carrier 2, as can be seen, different indexes The corresponding relationship between the corresponding logical channel and the carrier is different. Then, the terminal device can determine the carrier associated with the first logical channel and the carrier associated with the second logical channel according to the first index. If the adjustment information includes the corresponding index, the terminal device naturally knows how to set the first logic The carrier associated with the 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 carrier 1, the second logical channel has an association relationship with carrier 3, and carrier 2 has both the first logical channel and the second logical channel There is no association. The subsequent network device includes the first index through the adjustment information. 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 carrier 1 and carrier 2, and the second logical channel and carrier 3 If there is an association relationship, the terminal device may also establish an association relationship between carrier 2 and the first logical channel. Or, when the repetition 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. The subsequent network device includes the first index by adjusting the information. 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 carrier 1 and carrier 3, and the second logical channel and carrier 2 If there is an association relationship, the terminal device may disassociate the carrier 2 from the first logical channel, establish the association between the carrier 2 and the second logical channel, and disassociate the carrier 3 from the second logical channel, and establish the association between the carrier 3 and the second logical channel. The association relationship of a logical channel.

Of course, in addition to at least one of the above sub-modes, the adjustment mode may also include other modes for associating the carrier with the activated logical channel, which is not limited in this embodiment of the present application.

The adjustment method may be specified in the protocol. For example, the number of sub-modes included in the adjustment method specified in the protocol is greater than one. You can also use the signaling of the network device to indicate to the terminal device which type or types to use. Sub mode. For example, if the network device sends the adjustment information to indicate to the terminal device that the association relationship between at least one activated logical channel and the carrier to be adjusted is set according to the adjustment method, then the network device does not need to carry a specific adjustment method in the adjustment information The information, for example, the identification information of the adjustment method is the ID of the adjustment method. For example, the adjustment mode includes the above sub-mode 2, the network device may carry the ID of sub-mode 2 in the adjustment information, so that the adjustment information may indicate the association between at least one activated logical channel and the carrier to be adjusted according to the adjustment mode. Relationship, after receiving the adjustment information, the terminal device can determine the association relationship between the at least one activated logical channel and the carrier to be adjusted according to the sub-mode 2 ID according to the sub-mode 2. This approach helps reduce signaling overhead. Or, the adjustment method has been stipulated in the agreement. No matter whether the adjustment method specified in the agreement includes one or more of the above sub-modes, the adjustment information does not need to carry the adjustment method information (including the identification information of the adjustment method), as long as the network device After sending the adjustment information, the terminal device can adjust the association relationship between the carrier to be adjusted and at least one logical channel according to the adjustment method specified in the protocol and the information of the carrier to be adjusted included in the adjustment information. In this case, the adjustment information can also be Treated as a trigger message.

Or, the adjustment method may not be specified by the agreement, then the network device may also carry information about the specific adjustment method in the adjustment information. For example, the adjustment mode includes the above sub-mode 2, then the network device may carry the information of sub-mode 2 in the adjustment information, so that the adjustment information may indicate the association between at least one activated logical channel and the carrier to be adjusted according to the adjustment mode. Relationship, after receiving the adjustment information, the terminal device can determine the association relationship between setting at least one activated logical channel and the carrier to be adjusted according to sub-mode 2 according to the information of sub-mode 2, and clarify exactly what sub-mode 2 is the way. In this way, the terminal device can obtain clearer information.

The adjustment method may include at least one of the above several sub-methods, and other implementation forms. Or it may be understood that the adjustment method may include other methods in addition to at least one of the foregoing sub-modes.

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, carrying a bitmap corresponding to the first logical channel or corresponding to the first logical channel A bitmap of two logical channels, or a bitmap corresponding to the first logical channel and a bitmap corresponding to the second logical channel), the bitmap of the first logical channel is used to indicate the association relationship between the first logical channel and the carrier, and the The bitmap is used to indicate the association relationship between the second logical channel and the carrier. For example, 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 bitmap corresponding to the first logical channel. When at least one logical channel When the second logical channel is included, the adjustment information includes a bitmap corresponding to the second logical channel. Among them, a bitmap may correspond to the ID of a logical channel, for example, this correspondence may also be carried in the adjustment information, so that the terminal device can clarify the correspondence between the bitmap and the logical channel. In this case, the adjustment method may be a method of setting the association relationship between the carrier to be adjusted and at least one activated logical channel according to the bitmap included in the adjustment information, or the adjustment method is to set the carrier to be adjusted and the The manner of association between at least one activated logical channel.

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

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 instruct to deactivate the first logical channel, 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 relationship between the second logical channel and the carrier may change or may not Changes, if the association between the second logical channel and the carrier changes, the adjustment information can carry the bitmap corresponding to the second logical channel, and if the association between the second logical channel and the carrier does not change, then The adjustment information may carry the bitmap corresponding to the second logical channel to make the indication more clear, or may not carry the bitmap corresponding to the second logical channel, thereby reducing signaling overhead.

Or, if the previous signaling is used to indicate activation of the first logical channel, the adjustment information may also be used to indicate restoration of the original association relationship between the first logical channel and the carrier. The so-called original association relationship, that is, Before the first logical channel is deactivated, the association relationship between the first logical channel and the carrier. Since data packets copied at the PDCP layer are only transmitted through the first logical channel and the second logical channel, the adjustment information can also be regarded as an instruction to restore the original association relationship between the first logical channel and the carrier, and restore the first The original association between the two logical channels and the carrier. In this way, the adjustment information need not include the bitmap.

For example, a radio bearer is configured with a first logical channel and a second logical channel to transmit data packets copied at the PDCP layer, where the first logical channel is associated with carrier 1 and the second logical channel is associated with carrier 2 and carrier 3 There is an association relationship. After the repetition function of the PDCP layer of the radio bearer is activated, the first logical channel is instructed to be deactivated. After the first logical channel is deactivated, for example, the association relationship of carrier 1 and the second logical channel is established. After that, the network device instructs to activate the first logical channel through the first signaling, then the adjustment information may indicate to restore the original association relationship between the first logical channel and the carrier, and after receiving the adjustment information, the terminal device may reset the carrier 1 to When the first logical channel establishes an association relationship, the association relationship returns to that the first logical channel has an association relationship with carrier 1, and the second logical channel has an association relationship with carrier 2 and carrier 3. For example, the adjustment information can occupy 1 bit. If the value of this bit is "1", it means that the original association relationship is restored. If the value of this bit is "0", it means that the original value is not restored. Some associations. After the logical channel is deactivated and activated again, the original association relationship can be restored by simply adjusting the information without setting too many rules, and the implementation is relatively simple.

The adjustment information described above indicates the association relationship between the logical channel and the carrier by including a bitmap. The indication method is relatively clear and simple, and is convenient for the terminal device to set according to the indication information. In addition, in the manner described above, the adjustment information includes a bitmap. In another case, the network device may also send second signaling to the terminal device. The second signaling may be used to indicate activation or deactivation of the first logical channel or the first Two logical channels. The second signaling 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 the association relationship between the first logical channel and the carrier. The bitmap of the second logical channel is used to indicate the association relationship between the second logical channel and the carrier. In this case, the adjustment method may be a method of setting the association relationship between the carrier to be adjusted and at least one activated logical channel according to the bitmap carried by other signaling, or it may be understood that the adjustment method is to set the adjustment to be adjusted according to the bitmap The relationship between the carrier and at least one activated logical channel. 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 additional second signaling, so that the adjustment information and the bitmap can be relatively independent. If the bitmap is included through the second signaling, the implementation of the bitmap, etc., can refer to the previous introduction to the adjustment information including the bitmap. Whether the bitmap is included through the adjustment information or the second signaling depends on the specific implementation of the network device, or it can also be stipulated in the protocol without specific restrictions.

In addition, in addition to the implementation form of the adjustment manner described above, the adjustment manner may have other implementation forms. In other words, in addition to the methods described above, the adjustment method may also include one of the following several embodiments or any combination thereof.

As an implementation manner, the adjustment manner may be a manner of disassociating the first logical channel from 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 relationship between the first logical channel and the first carrier. For example, for the first logical channel, there is an association relationship with multiple carriers, and the channel quality of the first carrier is poor, and the first carrier has little effect on the transmission of data packets copied at the PDCP layer. Therefore, 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 can also be understood that the adjustment method may be a method of releasing the association relationship between at least one logical channel and the corresponding carrier, and the at least one logical channel may be the first logical channel and/or the second logical channel ( That is, the first logical channel or the second logical channel, or the first logical channel and the second logical channel), for each logical channel of at least one logical channel, the corresponding carrier may refer to the associated logical channel All carriers or some carriers. For example, the adjustment method may be a method of releasing the association relationship between the first logical channel and carrier 1 and a method of releasing the association relationship between the second logical channel and carrier 2.

As another embodiment, the adjustment method 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 removing the second carrier from The first logical channel moves to the second logical channel. The first logical channel and the second logical channel may be activated 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 relationship between the first logical channel and the second carrier , And establish an association relationship between the second carrier and the second logical channel. For example, the first logical channel has an association relationship with multiple carriers, and the channel quality of the multiple carriers is all good, but the channel quality of the carrier having an association relationship with the second logical channel may not be very good, then the network device It can instruct to disassociate the first logical channel and the second carrier, and establish the association between the second carrier and the second logical channel, thereby associating a carrier with a better channel quality for the second logical channel to improve transmission quality.

As yet another embodiment, the adjustment method may also be a method of establishing an association relationship between the first logical channel and the third carrier, and the third carrier is in an active state that has not established an association relationship between the first logical channel and the second logical channel State carrier. That is, the third carrier has not previously established an association relationship 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 through adjustment information. For example, the channel quality of the carrier that has an association relationship with the first logical channel may not be very good, and the channel quality of the third carrier is good, then the network device may instruct to associate the third carrier with the first logical channel, thereby improving Transmission quality.

Of course, in this embodiment, it is not limited to moving only one carrier, and the carriers can also be processed in batches. For example, the association relationship between the first logical channel and multiple carriers can be established. The carrier in the active state where the channel is associated with the second logical channel, and so on.

As mentioned above, various implementation forms of the adjustment method are introduced. As for which adjustment method is adopted, it can be specified by a protocol or configured by the network device in advance.

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