Background

In 5G, the service needs are classified into 3 application scenarios, enhanced Mobile Broadband (eMBB), mtc (massive Machine Type of Communication), urrllc (Ultra Reliable and Low Latency Communication), and the like. In the Release15URLLC issue, high reliability low latency traffic is considered and handled. In Rel-16, the IIoT project considers several items: time Sensitive Networking (TSN) network correlation enhancement; an intra-user priority; data replication transport and multi-connectivity.

For Data replication transmission and multi-connection Data replication and multi-connection, it has been described that existing Dual Connectivity and Carrier Aggregation replication (replication) or DC/CA replication some merging architecture can be optimized to further improve reliability. For Data replication transmission, an uplink Packet Data Convergence Protocol (PDCP) Data replication function may be configured based on a Data Bearer (DRB), and at most, two RLC entities are used to transmit a duplicate Data Packet (copy) at the same time, and the number of copies transmitted corresponds to the number of activated RLC entities. If two RLC entities are activated simultaneously, each RLC entity transmits one copy, and if only one RLC entity exists, the bearer only has one copy transmission.

However, the number of logical channels/RLC entities simultaneously supported for the same bearer (the number of legs supported by R16 is at least 1, including leg data is 1,2,3,4, 5.), and is greater than the number of legs supported by the existing data replication (the number of legs supported by R15 is 1, 2).

The communication system 100 further comprises at least one terminal device 120 located within the coverage area of the network device 110. As used herein, "terminal equipment" includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or means of another terminal device arranged to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A terminal device arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal", or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

Optionally, the communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that a device having a communication function in a network/system in the embodiments of the present application may be referred to as a communication device. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 may be the specific devices described above and are not described herein again; the communication device may also include other devices in the communication system 100, such as other network entities, for example, a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

In addition, in the related art, data replication is performed in the PDCP layer, and the same PDCP PDUs are mapped to different RLC entities, respectively. The MAC needs to transmit duplicate data of different RLC entities (RLC entity) to different carriers, where the number of the corresponding RLC entities may be at least one: 1,2,3,4, etc.

For the CA scenario, the scheme supporting data replication transmission (data replication) utilizes the data replication function of PDCP to enable the replicated PDCP PDUs to be transmitted to two RLC entities (two different logical channels) respectively, and finally ensures that the replicated PDCP PDUs can be transmitted on different physical layer aggregation carriers, thereby achieving frequency diversity gain to improve data transmission reliability. Such as DRB 1 and DRB 3 in fig. 1-2. :

for the DC scenario, the scheme supporting data replication transmission (data replication) utilizes the data replication function of PDCP, so that the replicated PDCP PDUs are respectively transmitted to two RLC entities, and the two RLC entities respectively correspond to different MAC entities. Such as DRB2 shown in fig. 1-2.

For data copy transmission, the uplink PDCP data copy function is configurable based on DRB, and at most two RLC entities are used to transmit copy at the same time, and the number of transmitted copies corresponds to the number of activated RLC entities. If two RLC entities are activated simultaneously, each RLC entity transmits one copy, and if only one RLC entity exists, the bearer only has one copy transmission. With the development of the technology, the situation that the logical channels do not correspond to the copies one by one is introduced, so that a corresponding solution needs to be provided for the scenario.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The first embodiment,

The embodiment provides a processing method for data replication transmission, which is applied to a terminal device, and as shown in fig. 2, the method includes:

step 21: determining the number of duplicate transmitted data packets transmitted by each logical channel/RLC entity in at least part of the at least one logical channel/RLC entity based on the first information, the second information and the third information;

wherein the content of the first and second substances,

It should be noted that, because the prior art supports a transmission mode in which one leg (i.e., a logical channel) carries one duplicate transmission packet (for example, may be referred to as copy), in R16, the leg number and the copy number may no longer be in one-to-one correspondence. Therefore, the problem of how to support this situation, selecting which leg transmits data, and carrying several copies on each selected leg needs to be considered. The advantage is that the problem of selecting which leg to transmit data and carrying several copies on each leg in the case that more than one leg of R16 is configured or activated is solved.

The Leg is configured to transmit a data packet of one PDCP entity through a plurality of RLC entities or logical channels when data is duplicated and transmitted, where one RLC entity or logical channel is referred to as one Leg. In this embodiment, let n be the number of legs.

The logical channel/RLC entity in this embodiment refers to a logical channel or an RLC entity; in other words, there is a one-to-one relationship between logical channels and RLC entities.

In the foregoing step 21, before determining, based on the first information, the second information and the third information, the number of duplicate transmitted data packets transmitted by each logical channel/RLC entity in at least some logical channel/RLC entities of the at least one logical channel/RLC entity, the method further includes:

the terminal device determines at least one of the first information, the second information and the third information based on at least one of channel quality, service characteristics, service priority, a predetermined threshold, time delay and reliability.

And/or receiving at least one of the first information, the second information and the third information sent by the network side.

That is, in this embodiment, at least one of the first information, the second information, and the third information may be determined by the terminal device, or may be determined by the network side. For example, the first information is determined by the terminal device, and then the second information and the third information may be determined by the network side and sent to the terminal device; or the first information and the second information are determined by the terminal equipment, and the third information is determined by the network side and is sent to the terminal equipment; or the first information and the third information are determined by the network equipment and are sent to the terminal equipment, and the second information is determined by the terminal equipment; the first information and the second information can be determined by the network equipment and sent to the terminal equipment, and the third information can be determined by the terminal equipment. Of course, other combination modes may exist, and are not described in detail in this embodiment.

It should be noted that the terminal device and the network device respectively determine different information, which is a case that the information determined by the terminal device is not overlapped with the information sent by the network device.

There may be a case where both the terminal device and the network device determine the same information, that is, the information determined by the terminal device itself and the information sent by the network device are partially repeated, for example, the terminal device itself determines the third information and receives the third information sent by the network device, and at this time, the information indicated by the terminal device or the network device may be determined to be used according to a preset rule.

Wherein the preset rule may include one of the following: the information determined by the terminal equipment is used as the final information; the information sent by the network equipment is used as the final information; selecting one of the information determined by the terminal equipment and the information sent by the network equipment as final use information; the terminal equipment and the network equipment negotiate to obtain finally used information; the terminal device determines the final information from the information sent from the network device.

For example, the terminal device itself determines the second information and also receives the second information sent by the network device; at this time, the terminal device can determine according to the rule that the terminal device performs subsequent processing by using the second information determined by the terminal device; or, the subsequent processing is performed by using the second information sent by the network device according to the rule determination subject to the network device. Or determined according to other rules, and will not be described in detail. The second information is taken as an example to be described in detail, and it can be understood that the first information, the second information, and the third information are all processed by using the above rule, but the embodiment is not exhaustive.

For example, when the channel quality of a certain logical channel/RLC entity is better, it may be determined that the number of data packets carried on the logical channel/RLC entity in the first information is greater, and/or it may be determined that the logical channel/RLC entity is used to transmit data packets for transmission of duplicate transmission in the third information; when the quality of one logical channel/RLC entity is poor, it may be determined that the logical channel/RLC entity is not used for transmitting the data packets for duplicate transmission in the third information, and/or the number of the data packets with a smaller number of data packets carried on the logical channel/RLC entity in the first information is determined. For another example, when the service priority of a certain logical channel/RLC entity is higher, it may be determined that more or less data packets are transmitted on the logical channel/RLC entity preferentially.

For another example, if the predetermined threshold of a logical channel/RLC entity, such as the threshold for transmitting data packets, is higher, and/or the reliability is higher, and/or the delay is lower, then a larger number of data packets for transmitting duplicate transmissions may be allocated on the logical channel/RLC entity, and conversely, a smaller number of data packets may be allocated.

It should be noted that the above is merely an example, and all of the above channel quality, service characteristics, service priority, predetermined threshold, time delay, and reliability may be actually integrated to determine at least one of the first information, the second information, and the third information corresponding to different logical channels/RLC entities, but this is not exhaustive here. In addition, the determination method of at least one of the three information by the network side is the same as that of the terminal device, and is not described again.

That is, in this embodiment, taking the second information as an example: the second information is determined by the base station. Alternatively, the second information is determined by the UE itself. Alternatively, the second information is determined by both the UE and the base station.

The manner of acquiring the second information by the terminal device may be: acquiring the second information based on the RRC reconfiguration message; the method can also comprise the following steps: the updated second Information is obtained based on one of Radio Resource Control (RRC), Media Access Control (MAC) Control Element (CE), and DownLink Control Information (DCI). That is, the initial second information is determined according to the RRC reconfiguration message, and the updated second information is determined according to the RRC/MAC CE/DCI indication.

In this embodiment, the terminal device determines which leg (i.e., logical channel/RLC entity) is selected to transmit data according to the third information.

The third information is determined by the base station, or by the terminal device, such as the UE itself, or by both the UE and the base station.

The transmission mode of the third information may be that the terminal device obtains the third information according to the dedicated message, for example, the third information is determined according to the RRC/MAC CE/DCI indication.

In this embodiment, the first information is determined by the base station, or determined by the UE itself, or determined by both the UE and the base station.

The transmission mode of the first information may be that the terminal device obtains the third information according to the dedicated message, for example, the third information is determined according to the RRC/MAC CE/DCI indication.

The UE may determine the first information according to at least one of channel quality, traffic characteristics, traffic priority, a predetermined threshold, latency, reliability, third information, and the second information.

It should be noted that the relevant information may be determined according to the relationship among the first information, the second information, and the third information. It can be said that at least one of the first information, the second information, and the third information may also be determined based on at least one of the first information, the second information, and the third information other than the information. For example: the first information may also be determined based on at least one of channel quality, traffic characteristics, traffic priority, a predetermined threshold, latency, reliability, the second information, and the third information.

In summary, several schemes provided by this embodiment may include:

and determining the number of copies carried on the leg according to the RRC reconfiguration message, and determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication.

And determining the number of copies carried on the leg according to the RRC reconfiguration message, and the UE self-determines which leg is used for transmitting data.

The number of copies carried on the leg is determined by itself, and the leg is used for transmitting data according to special information such as RRC/MAC CE/DCI indication.

The number of copies carried on a leg is determined by itself, and which leg is used to transmit data.

And the base station negotiates to determine the number of copies to be carried on the leg and which leg to use to transmit data.

And determining the total number of the load copies according to the RRC reconfiguration message, determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication, and determining the number of the load copies of each leg.

And determining the total number of the carrying copies according to the RRC reconfiguration message, determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication, and determining the number of the carrying copies of each leg by the UE.

And determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication. The UE determines the copy number and/or the copy total number of each leg bearer by itself.

The following description is made for several scenarios:

scene 1,

The terminal device itself determines the second information and the third information. The first information may also be determined by the terminal device, and may also be sent by the network side.

And the terminal equipment can determine the number of copies carried on the leg according to the second information.

Specifically, the manner of determining the first information, the second information, and the third information may be:

the terminal device determines the first information, the second information and the third information based on at least one of channel quality, service characteristics, service priority, a predetermined threshold, time delay and reliability.

For another example, if the predetermined threshold of a certain logical channel/RLC entity, for example, the threshold of the transmitted data packet, is higher, and the reliability is higher, then more data packets for transmitting duplicate transmission may be allocated on the logical channel/RLC entity, otherwise, less data packets may be allocated.

Correspondingly, the terminal equipment determines the number of data packets transmitted by amplitude values which can be borne by different logical channels/RLC entities according to the determined first information; determining the total number of the data packets according to the second information; then based on the total number of the data packets and the number of the data packets which can be carried by each logical channel/RLC entity; and determining the third information and determining the logic channel/RLC entity used at this time. And finally, determining the number of the data packets carried in each logical channel/RLC entity based on the logical channel/RLC entities to be used at this time. For another example, the second information is determined according to the selected leg and the first information, that is, the total number of data packets carried in the logical channel/RLC entity at this time is determined according to the selected logical channel/RLC entity (i.e., leg) and the number of duplicate transmitted data packets that each logical channel/RLC entity can carry.

For example, referring to fig. 3, a base station (i.e., a network side) determines a data duplication transmission and a configuration of the data duplication transmission first, and sends an existing data transmission configuration to a terminal device; the terminal equipment executes data copy transmission configuration and controls the transmission of the logical channel/RLC entity according to the initial mode configured in the configuration; the terminal equipment receives a data multiplexing transmission change instruction sent by a network side base station, wherein the change instruction can be only an instruction which needs the terminal equipment to change the transmission mode, and the specific change mode is not indicated; then, the terminal device determines the third information itself, determines which leg (i.e. logical channel/RLC entity) is used for transmission, determines the second information itself, and determines the copy number carried by each leg (logical channel or RLC entity), i.e. the total number of the duplicated and transmitted data packets, according to the second information.

It should be further noted that, although the determination of the first information is not shown in the figure, the first information may be actually determined when the terminal device determines the second information and the third information, and the manner of determining the first information may be as described above, and is not described herein again.

Optionally, the network side may also send the first information, that is, the network side, for example, the base station notifies that the total supported copy number of the bearer is configured as x, and then the UE determines the copy number that can be transmitted on the at least one logical channel/RLC entity configured corresponding to the bearer. For example, 3 logical channels are configured for one bearer, and 3 logical channels are selected for transmission, and if the total copy number supported by the bearer is 6, the terminal device determines that the copy number of each logical channel is 1,2, or 3.

The processing method provided by the present scenario has the advantage of giving the UE a flexible choice.

Scene 2,

In this scenario, the second information is sent by the network side, and the first information and the third information may be determined by the terminal device. And the UE determines the total number of the copies carried on the leg according to the RRC reconfiguration message, and the UE determines which leg is used for transmitting data.

Specifically, the receiving at least one of the first information, the second information, and the third information sent by the network side includes:

and acquiring the second information based on the RRC reconfiguration message.

The method may further comprise: and acquiring the updated second information based on one of RRC, MAC CE and DCI.

Further, the method further comprises: and determining the number of the data packets which can be carried by each logical channel/RLC entity and are subjected to the duplicate transmission based on the related configuration information of the data duplicate transmission mode and the second information sent by the network side, and transmitting the logical channel/RLC entities based on the data duplicate transmission mode.

In this scenario, when determining, based on the first information, the second information, and the third information, the number of duplicate packets transmitted by each logical channel/RLC entity in at least some logical channel/RLC entities of the at least one logical channel/RLC entity, the method further includes:

determining at least part of the at least two logical channels/RLC entities for duplicate data transmission based on the third information; and determining the number of the data packets which are carried by each logic channel/RLC entity and are duplicated to be transmitted in at least part of the logic channel/RLC entities, and transmitting the logic channel/RLC entities.

That is to say, the third information is determined by the terminal device itself, which has the advantages that the terminal device can more clearly know the channel quality information and can flexibly select a proper carrier or a proper logical channel/RLC entity to improve the reliability of data transmission.

The processing of this scenario will be described in detail with reference to fig. 4,5, and 6:

in fig. 4, a base station (i.e., a network side) first determines data copy transmission and configuration of the data copy transmission and second information, and sends the data transmission configuration and the second information to a terminal device; the terminal equipment determines the copy number correspondingly loaded by each leg (logical channel/RLC entity) according to the second information, executes data copy transmission configuration and controls the transmission of the logical channel/RLC entity according to the configured initial mode; and receiving data copy transmission change indication information from the base station.

With reference to fig. 5, the terminal device determines that a Data Bearer (DRB) changes a Data duplication transmission mode, determines third information by itself, and determines which leg (logical channel/RLC entity) is used for transmission based on the third information.

With reference to fig. 6, the base station (i.e. the network side) determines the data duplication transmission and the configuration of the data duplication transmission and the second information, and sends the data transmission configuration and/or the second information to the terminal device; the terminal equipment determines the copy number correspondingly loaded by each leg (logical channel/RLC entity) according to the second information, executes data copy transmission configuration and controls the transmission of the logical channel/RLC entity according to the configured initial mode; receiving data replication transmission change indication information and second information sent by a network side base station; and according to the change instruction, determining that the DRB changes the data replication transmission mode, determining third information by self, and determining which leg (logical channel/RLC entity) is used for transmission based on the third information.

Scene 3,

In this scenario, the third information is sent by the network side, and the first information and the second information may be determined by the terminal device. That is, the terminal device determines the number of copies carried on the leg by itself, and determines which leg is used to transmit data according to the specific information such as RRC/MAC CE/DCI indication.

The receiving at least one of the first information, the second information and the third information sent by the network side includes:

acquiring third information based on one of RRC, MAC CE and DCI; wherein the third information is used for indicating a logical channel/RLC entity used in the initial configuration data duplication transmission.

After receiving at least one of the first information, the second information, and the third information sent by the network side, the method further includes:

and acquiring the updated third information based on one of RRC, MAC CE and DCI.

The updated third information may be a logical channel/RLC entity used for acquiring the updated duplicate transmission.

In this scenario, the second information is determined by the UE itself, which has the advantages that the UE can make clearer the channel quality information, and can flexibly select which leg transmits more copies to achieve the purpose of increasing the reliability of data transmission with the minimum number of transmission times (for example, selecting a better leg to transmit more copies and a better leg to transmit less copies can reduce the number of retransmission times, increase the reliability, and decrease the transmission delay).

Or, the base station informs that the total supported copy number of the bearer is configured as x, and the UE determines the copy number that can be transmitted on at least one RLC entity configured corresponding to the bearer by itself.

Suppose that: if 3 logical channels are configured for one bearer, and the total copy number supported by the bearer is 6, the UE determines that the copy number of each logical channel is 1,2, and 3.

For an example of this scenario, referring to fig. 7, a base station (i.e., a network side) determines configurations of data replication transmission and data replication transmission first, and sends an existing data transmission configuration to a terminal device; the terminal equipment executes data copy transmission configuration and controls the transmission of the logical channel/RLC entity according to the initial mode configured in the configuration; and after receiving the data replication transmission change instruction information and the third information from the base station, the terminal equipment further changes the data replication transmission mode according to the change instruction, and determines which leg (logical channel/RLC entity) is used for transmission based on the third information. And self-determining second information, and determining the copy number of the bearer corresponding to each leg (logical channel/RLC entity) based on the second information. Optionally, the configured initial mode control logical channel/RLC entity may also be the third information.

Scene 4,

In this scenario, the third information and the first information may be determined by the network device. That is, based on the RRC reconfiguration message, obtaining the first information, that is, determining the number of copies carried on each leg according to the RRC reconfiguration message; and acquiring third information based on one of RRC, MAC CE and DCI, namely determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication.

Suppose that: a bearer is configured with 3 logical channels/RLC entities, and the copy number configured for each logical channel/RLC entity is 1,2,3, so that the total copy number supported by the bearer is 1+2+3 — 6.

The first information is indicated by a first information element in logical channel/RLC entity configuration information; or, the first information is indicated by a second information element in RLC entity configuration information.

For example, one of the first information formats: and adding a first information element IE in the logical channel Config configured by the logical channel/RLC entity. Such as: bearerdCopies estimated {1,2,3,4,5, spare3, spare2, spare1} is used to indicate that the associated logical channel/RLC entity supports the number of duplicate transport packets. Specifically, see the following:

as another example, in the first information format, a second information element IE is newly added to the RLC entity configuration information, such as RLC-BearerConfig. Such as "assisted channels estimated {1,2,3,4,5, spare3, spare2, spare1}, option R" — used to indicate that the associated logical channel/RLC entity supports the number of duplicate transport packets. Specifically, the following may be mentioned:

the third information may be indicated by dedicated information, and may be one of a MAC CE, a DCI message, and an RRC message. In one of the MAC CE, the DCI message and the RRC message, different columns correspond to different DRB IDs; different rows correspond to different logical channel/RLC entities associated with the DRB; and whether the RLC entities at the corresponding positions transmit the duplicated data or not is represented by the bits of different rows and different columns;

alternatively, the first and second electrodes may be,

in one of the MAC CE, the DCI message and the RRC message, different rows correspond to different DRB IDs; different columns correspond to different logical channel/RLC entities associated with different DRBs; and whether the RLC entity at the corresponding position transmits the duplicated data is characterized by bits of different rows and different columns.

An example of an alternative third information format is shown in fig. 10 below: e.g., the dedicated signaling is MAC CE. A 4byte MAC CE is introduced to indicate the activation/deactivation status of data replication transmission for each leg, 0 for deactivation and 1 for activation. Or, for indicating whether each leg transmits a PDCP PDU or a copy thereof. Different columns correspond to different DRB IDs, and the corresponding mode is consistent with the existing protocol; different rows correspond to different RLC entities associated with a DRB; the value in the bit indicates whether duplicate data is transmitted using the RLC entity.

Specifically, the method comprises the following steps:

for example, the MCG has 2 DRBs configured with the duplicated data transmission function, and the DRBs IDs are 0, 3,5, and 7;

the format of the MAC CE is 4 bytes, and the DRBs are mapped to the DRBs in ascending order of DRB ID from the 1 st column to the 4 th column. For example, columns D0, D1, D2, and D3 correspond to DRB IDs 0, 3,5, and 7, respectively.

Different rows in each column indicate which RLC entities are employed to transmit duplicate data, and in particular, a maximum of 4 RLC entities may be indicated to transmit duplicate data in this example. Sorting according to the sequence of a Master Cell Group (MCG) and a Secondary Cell Group (SCG), and sorting in each CG according to the ascending order or the descending order of logical channel IDs. Or the data is sorted according to the order of SCG first and then MCG, and sorted in each CG according to the ascending order or the descending order of the logical channel ID. For example, for each row of DRB0, from top to bottom, respectively, for

RLC entities

0,1,2,3, respectively. Alternatively, as shown in fig. 11, similar to the description of fig. 10, the differences are that the columns are changed into the rows, and the description is omitted.

The specific process is described below, taking fig. 8 and 9 as examples:

the base station determines whether to use the data copy transmission mode and the related configuration information of the data copy transmission mode.

The base station determines to use the data replication transmission mode, and informs the UE of configuration information corresponding to the data replication mode, and the first information is used for indicating the number of copies that each leg can bear.

And the base station informs all the data replication transmission configuration information and the first information through an RRC reconfiguration message.

And determining the number of data packets which can be carried by each logical channel/RLC entity and are subjected to the duplicate transmission based on the related configuration information of the data duplicate transmission mode and the first information sent by the network side, and transmitting the logical channel/RLC entities based on the data duplicate transmission mode. That is, the UE receives the RRC message from the base station, configures the RLC entity, determines and stores the copy number that each leg can carry according to the first information, and then transmits the copy number according to the initial copy data transmission method.

When the base station determines that the data copy transmission mode needs to be changed, such as activation/deactivation of data copy transmission, as shown in fig. 8, the base station sends a data multiplexing transmission change instruction, and the UE changes the data copy transmission mode according to the change instruction; alternatively, as shown in fig. 9, the base station transmits the data multiplex transmission change instruction and the third instruction; and the UE determines which leg (namely the logical channel/RLC entity) is used for transmission according to the third information, and changes the data copying transmission mode.

Determining at least part of the at least two logical channels/RLC entities for duplicate data transmission based on third information sent by the network side; and determining the number of the data packets which are carried by each logic channel/RLC entity and are duplicated to be transmitted in at least part of the logic channel/RLC entities, and transmitting the logic channel/RLC entities. That is, the UE receives a change indication message of the data replication method from the base station, such as the MAC CE, and selects an appropriate leg according to the change indication of the data replication transmission, or according to the change indication of the data replication transmission and the third information, to perform an activation or deactivation operation, and then perform the replicated data transmission.

Scene 5,

And negotiating with the network side, and determining at least one of the first information, the second information and the third information. I.e. the UE and the base station negotiate to determine the number of copies carried on the leg and/or which leg to use for transmitting data.

Referring to fig. 12, the second information and the third information are negotiated and determined by the UE and the base station, which is advantageous in that the UE is given flexible choice while ensuring the degree of control of the UE by the base station.

Scene 6,

In this scenario, the third information and the second information may be determined by the network device. That is, based on the RRC reconfiguration message, acquiring the second information, that is, determining the total number of copies carried on the leg according to the RRC reconfiguration message; and acquiring third information based on one of RRC, MAC CE and DCI, namely determining which leg is used for transmitting data according to the RRC/MAC CE/DCI indication.

The second information is indicated by a first information element in logical channel/RLC entity configuration information; or, the second information is indicated by a second information element in RLC entity configuration information; or, the second information is indicated in PDCP entity configuration information.

For example, one of the second information formats: newly adding a first information element IE in the logical channel configuration LogicalChannelConfig; for another example, the second information format is that a second information element IE is newly added to RLC entity configuration information, such as RLC-BearerConfig.

The third information may be indicated by dedicated information, and may be one of a MAC CE, a DCI message, and an RRC message. In one of the MAC CE, the DCI message and the RRC message, different columns correspond to different DRB IDs; different rows correspond to different logical channel/RLC entities associated with the DRB; and whether the logical channel/RLC entity at the corresponding position transmits the duplicated data or not is represented by the bits of different rows and different columns;

alternatively, the first and second electrodes may be,

in one of the MAC CE, the DCI message and the RRC message, different rows correspond to different DRB IDs; different columns correspond to different logical channel/RLC entities associated with different DRBs; and whether the logical channel/RLC entity at the corresponding position transmits the duplicated data is characterized by bits of different rows and different columns.

An alternative third information format is shown in fig. 10, for example: e.g., the dedicated signaling is MAC CE. A 4byte MAC CE is introduced to indicate the activation/deactivation status of data replication transmission for each leg, 0 for deactivation and 1 for activation. Or, for indicating whether each leg transmits a PDCP PDU or a copy thereof. Different columns correspond to different DRB IDs, and the corresponding mode is consistent with the existing protocol; different rows correspond to different logical channels/RLC entities associated with a DRB; the value in the bit indicates whether duplicate data is transmitted using the RLC entity. Alternatively, as shown in fig. 11, similar to the description of fig. 10, the differences are that the columns are changed into the rows, and the description is omitted.

The specific scheme is described as follows:

And the base station determines to use the data copy transmission mode and informs the UE of configuration information corresponding to the data copy mode and second information, wherein the second information is used for indicating the total number of the copies carried.

And the base station informs all the data replication transmission configuration information and the second information through the RRC reconfiguration message.

And determining the number of the data packets which can be carried by each logical channel/RLC entity and are subjected to the duplicate transmission based on the related configuration information of the data duplicate transmission mode and the second information sent by the network side, and transmitting the logical channel/RLC entities based on the data duplicate transmission mode. That is, the UE receives the RRC message from the base station, configures the logical channel/RLC entity, determines and stores the copy number that each leg can carry according to the second information, and then transmits the copy number according to the initial copy data transmission method.

When the base station judges that the data copying mode needs to be changed, such as data copying transmission activation/deactivation, sending a data multiplexing transmission change instruction, and changing the data copying transmission mode by the UE according to the change instruction; or, the base station sends a data multiplexing transmission change instruction and a third instruction; and the UE determines which leg (namely the logical channel/RLC entity) is used for transmission according to the third information, and determines the number of data packets carried in each logical channel/RLC entity.

It can be seen that, by adopting the above scheme, when one logical channel/RLC entity can transmit a plurality of data packets of duplicated data, the adopted logical channel/RLC entity and the number of data packets of duplicated transmission transmitted on different logical channel/RLC entities can be determined. Therefore, the requirement of R16 that more flexible and effective data replication transmission is introduced can be met, the number of corresponding logical channel/RLC entities can be increased, and the number of the logical channel/RLC entities and the number of data packets to be replicated and transmitted are not in one-to-one correspondence, so that the effective utilization of system resources is ensured, and the flexible and effective transmission of data is ensured.

Example II,

The present embodiment provides a processing method for data replication and transmission, which is applied to a network device, and as shown in fig. 13, the method includes:

step 31: sending at least one of the first information, the second information and the third information to the terminal equipment;

wherein the content of the first and second substances,

It should be noted that, since the prior art supports a transmission mode in which one leg (i.e. logical channel/RLC entity) carries one duplicate transmission packet (for example, may be referred to as copy), in R16, the leg number and the copy number may not be in one-to-one correspondence. Therefore, the problem of how to support this situation, selecting which leg transmits data, and carrying several copies on each selected leg needs to be considered. The advantage is that the problem of selecting which leg to transmit data and carrying several copies on each leg in the case that more than one leg of R16 is configured or activated is solved.

Here, the Leg is that when data is duplicated and transmitted, a data packet of one PDCP entity may be transmitted by a plurality of RLC entities or logical channels/RLC entities, where one RLC entity or logical channel may be referred to as one Leg. In this embodiment, let n be the number of legs.

The network device may determine at least one of the first information, the second information, and the third information based on at least one of channel quality, traffic characteristics, traffic priority, a predetermined threshold, latency, and reliability.

The manner of sending the second information by the network device may be: sending the second information to the terminal equipment based on the RRC reconfiguration message; the method can also comprise the following steps: transmitting the updated second information based on one of RRC, MAC CE, and DCI. That is, the initial second information is determined according to the RRC reconfiguration message, and the updated second information is determined according to the RRC/MAC CE/DCI indication.

The third information is determined by the base station, or by the UE itself, or by both the UE and the base station.

In this embodiment, the terminal device may be a user equipment UE, and the network device may be a base station on a network side.

In summary, several schemes provided by this embodiment may include:

The following description is made for several scenarios:

scene 1,

For example, referring to fig. 3, a base station (i.e., a network side) determines a data duplication transmission and a configuration of the data duplication transmission first, and sends an existing data transmission configuration to a terminal device; the terminal equipment executes data copy transmission configuration and controls the transmission of the logical channel/RLC entity according to the initial mode configured in the configuration; the terminal equipment receives a data multiplexing transmission change instruction sent by a network side base station, wherein the change instruction can be only an instruction which needs the terminal equipment to change the transmission mode, and the specific change mode is not indicated; then, the terminal device determines the third information itself, determines which leg (logical channel/RLC entity) is used for transmission, determines the second information itself, and determines the copy number carried by each leg (logical channel or RLC entity), i.e. the number of data packets to be transmitted in duplicate, according to the second information.

Optionally, the network side may also send the first information, that is, the network side, for example, the base station notifies that the total supported copy number of the bearer is configured as x, and then the UE determines the copy number that can be transmitted on at least one RLC entity configured corresponding to the bearer. For example, 3 logical channels are configured for one bearer, and 3 logical channels are selected for transmission, and if the total copy number supported by the bearer is 6, the terminal device determines that the copy number of each logical channel is 1,2, or 3.

Scene 2,

For example, one of the first information formats: newly adding a first information element IE in a logical channel Config configured by a logical channel/RLC entity; for another example, the second information format is that a second information element IE is newly added to RLC entity configuration information, such as RLC-BearerConfig. The specific format may be the same as that in the first embodiment, and is not described again.

In one of the MAC CE, the DCI message and the RRC message, different columns correspond to different DRB IDs; different rows correspond to different RLC entities associated with the DRBs; and whether the RLC entities at the corresponding positions transmit the duplicated data or not is represented by the bits of different rows and different columns;

alternatively, the first and second electrodes may be,

in one of the MAC CE, the DCI message and the RRC message, different rows correspond to different DRB IDs; different columns correspond to different RLC entities associated with different DRBs; and whether the RLC entity at the corresponding position transmits the duplicated data is characterized by bits of different rows and different columns.

Specifically, the method comprises the following steps:

Different rows in each column indicate which RLC entities are employed to transmit duplicate data, and in particular, a maximum of 4 RLC entities may be indicated to transmit duplicate data in this example. The MCG and SCG are sorted in sequence, and the logical channel IDs are sorted in ascending or descending order in each CG. Or the data is sorted according to the order of SCG first and then MCG, and sorted in each CG according to the ascending order or the descending order of the logical channel ID. For example, for each row of DRB0, from top to bottom, respectively, for

RLC entities

Alternatively, as shown in fig. 11, similar to the description of fig. 10, the differences are that the columns are changed into the rows, and the description is omitted.

That is, the UE receives the RRC message from the base station, configures the RLC entity, determines and stores the copy number that each leg can carry according to the second information, and then transmits the copy number according to the initial copy data transmission method.
