Background technique

Based on its transmission requirements for delay and reliability, IIoT introduces the concept of time sensitive network (English: Time sensitive network, TSN for short) or TSC. In order to provide high-reliability and low-latency transmission effects for its services, the research direction of data duplication and multi-connectivity has been introduced, and the inclusion of data is determined in NR IIoT WID (RP-190728) The dual connectivity (English: Dual connectivity, abbreviation: DC) and carrier aggregation (English: Carrier aggregation, abbreviation: CA) combines a Duplication architecture to further improve reliability.

Data replication is performed at the Packet Data Convergence Protocol (English: Packet Data Convergence Protocol, abbreviated as: PDCP) layer, and the same PDCP protocol data unit (English: Protocol Data Unit, abbreviated as: PDU) is mapped to different radio link layer control protocols. (English: Radio Link Control, RLC for short) entity. Data replication transmission, also known as PDCP replication transmission. The media access control layer (English: Media Access Control, abbreviated as: MAC) needs to transmit the copied data of different RLC entities to different carriers. At this time, the number of corresponding RLC entities can be at least one.

For CA scenarios, the solution that supports data replication and transmission uses PDCP's data replication function, so that the replicated PDCP PDU is transmitted to two RLC entities (two different logical channels), and finally it is guaranteed that the replicated PDCP PDU can be in different physical layers Transmission on aggregated carriers to achieve frequency diversity gain to improve data transmission reliability. For the DC scenario, the solution supporting data duplication utilizes the data duplication function of PDCP, so that the duplicated PDCP PDU is transmitted to two RLC entities respectively, and the two RLC entities correspond to different MAC entities.

For scenarios where DC and CA are combined, and there are multiple replication transmission mechanisms, it is necessary to consider at least two replication transmission mechanism changes and how to deal with coexistence scenarios.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

The terms "first", "second", etc. in the description, claims, and the foregoing drawings of the embodiments of the present application are used to distinguish similar objects, rather than to describe a specific sequence or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein, for example, can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to the clearly listed Those steps or units may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment.

The following conclusions were reached in the RAN2#106 meeting:

Intention is that Copies are sent on different legs

Dynamic Network control of DRB duplication is by MAC CE

By the MAC CE, Network to control which of the configured RLC entities that is/are active

Support the case that no of copies = no of active RLC entities

In the current discussion, at least three duplication transmission mechanisms (also known as duplication transmission change mechanisms) can be considered:

The first type of replication transmission mechanism is the NW-based duplication mechanism, which is a solution that completely controls the replication transmission on the network side. For all packets transmitted on the DRB, the network side indicates whether to perform duplication transmission, and/or which path to choose (leg ) Perform copy transmission, for example: MAC CE can be used to indicate.

The second duplication transmission mechanism is UE-based duplication mechanism, which is based on network configuration or predefined rules (criteria), for all transmission packets (packet) transmitted on the data radio bearer (English: Data Radio Bearer, abbreviation: DRB) ), the UE selects whether to perform copy transmission and which path (leg) to select for copy transmission.

The third type of replication transmission mechanism is a packet-based duplication mechanism, that is, based on network configuration or predefined rules (criteria), only partial packets of a bearer are replicated and transmitted, and which path is selected for replication transmission.

The "first", "second", and "third" in the above description do not indicate a specific copy transmission mechanism, nor do they indicate a specific order.

Figure 1 is a schematic diagram of the PDCP replication transmission provided by this application. As shown in Figure 1, data replication is performed at the Packet Data Convergence Protocol (English: Packet Data Convergence Protocol, abbreviated as: PDCP) layer, and the same PDCP protocol data unit (English: Protocol Data Unit, abbreviated as: PDU) are respectively mapped to different radio link layer control protocol (English: Radio Link Control, abbreviated as: RLC) entities. Data replication transmission, also known as PDCP replication transmission. The media access control layer (English: Media Access Control, abbreviated as: MAC) needs to transmit the copied data of different RLC entities to different carriers. At this time, the number of corresponding RLC entities can be at least one.

For carrier aggregation (English: Carrier aggregation, abbreviation: CA) scenarios, the solution that supports data duplication uses PDCP's data duplication function, so that the duplicated PDCP PDUs are transmitted to two RLC entities (two different logic Channel), and finally ensure that the copied PDCP PDU can be transmitted on aggregated carriers of different physical layers, so as to achieve frequency diversity gain and improve data transmission reliability. DRB 1 and DRB 3 in Figure 1. For dual connectivity (English: Dual connectivity, abbreviation: DC) scenarios, the solution that supports data duplication utilizes the data duplication function of PDCP, so that the duplicate PDCP PDUs are transmitted to two RLC entities respectively, and the two RLC entities respectively Correspond to different MAC entities (MCG MAC entity or SCG MAC entity). As shown in DRB 2 in Figure 1.

However, the current technical solution only supports the activation/deactivation solution of network-based replication transmission. For the above-mentioned scenarios that can support at least two replication transmission modification mechanisms, it is necessary to consider how to deal with scenarios where at least two replication transmission modification mechanisms coexist. For example, if a copy transmission based on a copy transmission change mechanism is currently triggered, a copy transmission instruction based on another copy transmission change mechanism is immediately received or whether to change the copy transmission status, etc., or which type of UE priority follows For the copy transmission indicated by the change mechanism, no corresponding solution is provided in the prior art.

In response to the above problems, the present application provides a method for processing copy data transmission to provide a technical solution for how to deal with the scenario where at least two copy transmission change mechanisms coexist. The following is a description of several specific implementations.

2 is a flowchart of Embodiment 1 of a method for processing copy data transmission provided by this application; as shown in FIG. 2, this solution is mainly applied between a network device and a UE. The method for processing copy data transmission provided in this embodiment is specifically It includes the following steps:

S101: Configure an initial replication state and use conditions of at least one replication transmission change mechanism for the UE.

In this step, during the data transmission process of the UE, if you need to use the copy transmission method, first the network equipment needs to be configured to carry the identification of the corresponding logical channel, the cell group identification information, and the initial replication state (also called Is the initial copy transmission state), indicating that the initial state of the copy transmission is an activated or deactivated state, for example: the initial copy state is a copy transmission deactivated state.

In this solution, since there are multiple replication transmission modification mechanisms, it can be seen from the above description that at least two replication transmission modification mechanisms are involved in the specific implementation of this solution. Therefore, one of the mechanisms is used for transmission. , The UE needs to know when the conditions are met to determine the new replication transmission status according to other replication transmission modification mechanisms, so the network equipment can also configure at least one replication transmission modification mechanism usage conditions, and when the corresponding usage conditions are met, it can be based on The corresponding replication transmission change mechanism determines the status of the replication transmission.

S102: Send replication transmission configuration information to the UE.

In this step, after the network device has configured the initial replication state, it needs to indicate the configuration to the UE, and can then send the UE the first indication information for indicating the initial replication state and/or at least one replication transmission change Copy transmission configuration information of the use condition of the mechanism.

Optionally, in another implementation of the solution, the network device may also configure a timer for maintaining the initial replication state for the UE. Optionally, the network device may also be configured with at least one timer that replicates the transmission change mechanism. Therefore, the replication transmission configuration information may include at least one of the following: first indication information for indicating the initial replication status, a timer for maintaining the initial replication status, at least one use condition of the replication transmission modification mechanism, and at least one Copy the timer of the transmission change mechanism.

Optionally, in another implementation of the solution, the network device can also configure at least one priority of the replication transmission change mechanism for the UE, and the network device can also configure the priority of the initial replication state for the UE, so the replication transmission configuration The information may include at least one of the following: first indication information for indicating the initial replication status, the priority of the initial replication status, the priority of at least one replication transmission modification mechanism, and the use condition of at least one replication transmission modification mechanism, at least one Copy the timer of the transmission change mechanism.

In the technical solution of the present application, it should be understood that different replication transmission modification mechanisms are network device configurations or different predefined data replication transmission determination methods.

S103: Configure the initial replication state of the UE according to the first indication information.

The UE receives the replication transmission configuration information sent by the network device side, determines the replication transmission status according to the first indication information indicating the replication transmission status therein, and executes the corresponding transmission scheme.

Optionally, when the initial replication state timer is configured in the replication transmission configuration information, the timer is started when the initial replication state is enabled.

The processing method of the replication data transmission provided in this embodiment mainly requires the network device to configure the initial replication status at the beginning of the data transmission process of the UE, and at the same time, the use conditions of each subsequent replication transmission change mechanism can be configured to facilitate After the conditions are met, the replication transfer status can be changed directly.

In any embodiment of the present application, the involved replication transmission modification mechanism includes at least the following types:

The first type is to determine the replication transmission status and/or transmission path according to the information sent by the network device for all data transmitted on the DRB.

That is, the aforementioned first copy transmission mechanism is completely controlled by the network device. The network device indicates the status of the copy transmission and/or the transmission path used during the copy transmission. The UE only needs to determine the following according to the information sent by the network device side At least one: the copy transmission is activated or deactivated, and the data transmission path.

The second type is to determine the replication transmission status and/or the transmission path according to at least one of the carrier configured by the network device, the replication status change rule, and the path determination rule for all data transmitted on the DRB.

That is, the aforementioned second copy transmission mechanism. This mechanism is that the UE itself determines the copy transmission status and/or transmission path of all data transmitted on the DRB. That is, in the aforementioned second copy transmission mechanism, the UE chooses whether to perform copy transmission and which transmission path to choose for data transmission. In a specific implementation, the UE determines whether to implement the UE-based duplication transmission mechanism according to network configuration rules; or, the UE can determine the replication transmission status and/or the transmission path of data transmission by network configuration rules. Specifically, the UE may determine the replication transmission status, and/or the transmission path of the transmission data according to the carrier configured by the network device and the replication status change rule, and/or the UE according to the path determination rule configured by the network device. Optionally, in another specific implementation, it can also be a way in which the UE is fully controlled. For example, the UE completely determines whether to implement the UE-based duplication transmission mechanism, that is to say, the replication state change rule and the path determination rule are both determined by the UE. Self-determined or pre-defined, no network equipment is required for configuration, and there is no restriction on this solution.

The third type is to determine the replication transmission status and/or the transmission path according to at least one of the carrier configured by the network device, the replication status change rule, and the path determination rule for part of the data transmitted on the DRB.

That is to say, the third copy transmission mechanism mentioned above. The difference from the second copy transmission change rule mentioned above is that this scheme is performed on part of the data transmitted on the DRB, which means that the UE itself determines whether to copy part of the data. Transmission, and which transmission path is selected for transmission when copying transmission.

In the technical solution of this application, it should be understood that the transmission path refers to the RLC entity, leg, logical channel, carrier, etc. used when copying and transmitting data on the DRB.

FIG. 3 is a flowchart of Embodiment 2 of the method for processing copy data transmission provided by this application; as shown in FIG. 3, the method for processing copy data transmission provided by this embodiment is applied between a network device and a UE and includes at least the following steps :

S201: When the UE is in the first replication transmission state and it is detected that the UE meets the use conditions of the second replication transmission modification mechanism, change from the first replication transmission state to the second replication transmission state according to the second replication transmission modification mechanism .

In the technical solution of the present application, the different modification mechanisms are network device configurations or different predefined data replication and transmission determination methods. For specific replication and transmission modification mechanisms, refer to the foregoing description.

In this solution, the UE is currently in a replication transmission state. The replication transmission state can be the initial replication state configured by the network device in the above-mentioned embodiment, or it can be a state after a change in accordance with a change instruction or any replication transmission change mechanism. No restrictions. The following embodiment only describes the solution with the current replication transmission state being the first replication transmission state determined by the first replication transmission modification mechanism, and does not restrict the UE to be in this state.

When it is detected that the UE meets the use conditions of the second replication transmission modification mechanism, it is determined that the second replication transmission modification mechanism can be used to re-determine the replication transmission status. At this time, the replication transmission status can be determined according to the second replication transmission modification mechanism. To make changes, the second copy transmission change mechanism can be any of the aforementioned copy transmission change mechanisms, which is not limited in this solution. In the specific change process, the UE determines the second copy transmission state according to the second copy transmission change mechanism, and changes the current first copy transmission state to the second copy transmission state.

In a specific implementation of the solution, if the first replication transmission status is the replication transmission status determined according to the first replication transmission modification mechanism, and the first replication transmission modification mechanism is the aforementioned first replication transmission modification mechanism, That is, for all data transmitted on the data radio bearer DRB, the replication transmission status and/or transmission path are determined according to the information sent by the network device. Before this step is executed, it also includes the following steps:

When the network device determines that it needs to change the transmission state, it determines the first copy transmission state to be changed, and sends first information to the UE, which carries the first copy change indication and/or transmission corresponding to the first copy transmission change mechanism Path indication, the first replication change indication is used to instruct the UE to change the replication transmission state to the first replication transmission state. Optionally, the first information may be DCI or MAC CE, or other downlink information, which is not limited in this solution. The UE receives the first information sent by the network device, where the first information carries the first copy change indication and/or the transmission path indication corresponding to the first copy transmission change mechanism, and then, according to the first copy change instruction Change the replication transmission state to the first replication transmission state, and/or determine the transmission path according to the transmission path indication.

For example: when the network device determines that it needs to modify the status of the duplication, such as modifying the duplication status from activated to deactivated, or when performing the leg/RLC entity that replicates data transmission, the network device uses the first duplication modification mechanism to change The duplication state of the UE or the UE's bearer is changed to the first duplication transmission state. For example, the network device notifies the UE of the first change indication information indicating the change to the first duplication transmission state through DCI or MAC CE. After receiving the first change indication information, the UE modifies the current duplication state according to the first change indication information, and changes to the first duplication transmission state. For example, the initial state is duplication deactivated state. According to the MAC CE notified by the network device, the UE determines to change from the duplication deactivated state to the duplication activated state, and can also determine to use the

RLC entity

1, 2, 4 to transmit duplication data.

In another specific implementation of the solution, if the second replication transmission modification mechanism is the aforementioned second or third replication transmission modification mechanism, that is, for all or part of the data transmitted on the data radio bearer DRB, according to At least one of the carrier, the replication status change rule, and the path determination rule configured by the network device determines the replication transmission status and/or the transmission path. Then, when changing from the first copy transmission state to the second copy transmission state, first, the second copy transmission state can be determined according to at least one of the carrier configured by the network device, the copy state change rule, and the path determination rule, and then the second copy transmission state can be determined. The first copy transmission state is changed to the second copy transmission state.

For example: when the UE determines that the use conditions of the second duplication transmission change mechanism configured by the network device are met, the UE modifies the current duplication state and changes to the second duplication state, and the second duplication state is based on the second duplication transmission The change mechanism is determined. For example, the use judgment condition of the second replication transmission change mechanism configured by the network equipment is that the channel quality RSRP of any serving cell or primary cell is greater than the threshold M, and the duplication activated state is changed to the deactivated state. When the UE determines that this condition is met, if the RSRP of cell1 corresponding to RLC entity 1 is greater than the threshold M, the UE determines to change from duplication activated state to duplication deactivated state, and uses RLC entity 1 or cell1 corresponding to RLC entity 1 to transmit data.

For another example: when the UE determines that the use conditions of the third duplication transmission change mechanism configured by the network are met, the UE modifies the current duplication state and changes to the third duplication state, which is based on the third duplication transmission The change mechanism is determined. For example, corresponding to a certain bearer, its current status is duplication deactivated status, and the use judgment condition of the third replication transmission change mechanism configured by the network device is that the DRB carries a specific QFI or a specific data packet (such as an IR packet, an I-frame packet) , Or when receiving a handover command, or receiving a PDCP data recovery indication, or when the channel quality is less than the threshold, packet-based duplication transmission is triggered. When the UE determines that this condition is met, for example, when the currently carried packet in the bearer has an IR packet, or when the currently carried packet in the bearer has an IR packet and the channel quality of the primary cell is less than the threshold, the UE changes to the third duplication state, And only for the IR packet, the UE performs duplication transmission. That is, the UE performs duplication transmission on the IR packet, but does not perform duplication transmission on the data packet in the bearer.

S202: Perform data transmission according to the second copy transmission state.

In this step, after changing the replication transmission state, the UE uses the second replication transmission state to transmit the data carried on the DRB.

In a specific implementation of the solution, if the second copy transmission change mechanism is the aforementioned first copy transmission change mechanism, the transmission path of the transmitted data can be determined directly according to the instructions of the network device. If the second copy transmission change mechanism is the aforementioned first or second or third copy transmission change mechanism, when data transmission is performed according to the second copy transmission state, the UE may change the mechanism according to the second copy transmission The path determination rule determines the transmission path for transmitting all data or part of the data, and then transmits all data or part of the data on the determined transmission path according to the second copy transmission state.

After the completion of the above-mentioned replication transmission status change, if the UE again receives the change instruction information sent by the network device or meets the use conditions of any replication transmission modification mechanism, the replication transmission status is changed again according to the above scheme.

In the method for processing replicated data transmission provided in this embodiment, when the UE is in a replication transmission state and meets the use conditions of other second replication transmission modification mechanisms, it is directly changed to the second replication transmission modification mechanism determined according to the second replication transmission state. 2. Copy the transmission status.

FIG. 4 is a flowchart of Embodiment 3 of the method for processing copy data transmission provided by this application. As shown in FIG. 4, the method for processing copy data transmission provided by this embodiment is applied between a network device and a UE and includes at least the following steps :

S301: When the UE starts the first replication transmission state, start a first timer, where the first timer is a timer configured by the network device to maintain the first replication transmission state.

In this step, the network device can pre-configure a timer for maintaining the state of at least one replication transmission state, or predefine a timer for maintaining at least one replication transmission state. Optionally, it can also be for at least one replication transmission state. The transmission change mechanism configuration or the predefined timer, after the replication status is changed according to a certain copy transmission change mechanism, starts the timer corresponding to the copy transmission change mechanism, which is not limited in this solution.

In addition, the length of the timer configured or predefined for maintaining the state of at least one replication transmission state, or the timer configured or predefined for at least one replication transmission modification mechanism may be the same or different. .

When the UE starts to adopt the first replication transmission state, it also starts the first timer that maintains the first replication transmission state for timing, that is, before the first timer expires, whether it meets other replication transmission change mechanisms or not The conditions of use, whether the network device has sent a change instruction or not, remain in the first copy transmission state.

In the technical solution of the present application, different replication transmission modification mechanisms are network device configurations or different predefined data replication transmission determination methods. For specific replication transmission modification mechanisms, refer to the foregoing description. In this solution, the UE starts the first replication transmission state, which can be the initial replication state configured by the network device in the above embodiment, or the state after a change in accordance with a change instruction or any replication transmission change mechanism, which is not limited.

S302: When the first timer expires, change from the first replication transmission state to the second replication transmission state.

In this step, the meaning is that after the first timer expires, the replication transmission status can be changed. The change includes receiving a change indication of the replication transmission status of the network device, or satisfies other replication transmission change mechanisms According to the use conditions of the copy transmission change mechanism, a new copy transmission state can be determined. For example: the second replication transmission status in this solution includes: the replication status determined according to the change instruction sent by the network device, or the replication transmission status determined according to the second replication transmission change mechanism when the conditions for use of the second replication transmission change mechanism are met .

In a specific implementation of this solution, when the first timer expires, the change from the first replication transmission state to the second replication transmission state includes at least the following situations:

In the first case, during the operation of the first timer, if the change instruction sent by the network device is received or the use condition of the second replication transmission change mechanism is met, then when the first timer expires, from The first copy transmission state is changed to the second copy transmission state.

The meaning of this solution is that during the timing of the first timer, a change instruction to change the replication transmission state to the second replication transmission state is received from the network device, and the change is not made for the time being, and when the first timer expires, Then change from the first copy transmission state to the second copy transmission state. Or, in the process of counting the first timer, it is detected that the UE meets the conditions of use of the second copy transmission change mechanism, and the change is not made temporarily. When the first timer expires, the second copy transmission change mechanism is changed from the first The copy transmission state is changed to the second copy transmission state.

In the second case, after the first timer expires, if the change instruction sent by the network device is received or the use condition of the second copy transmission change mechanism is met, the first copy transmission state is changed to the first copy transmission state. 2. Copy the transmission status.

The meaning of this solution is that after the first timer expires, if a change instruction to change the replication transmission state to the second replication transmission state is received from the network device or it is detected that the UE meets the use of another second replication transmission change mechanism Condition, the first copy transmission state is changed to the second copy transmission state.

The main purpose of the above implementation scheme is to change the state after the first timer expires, regardless of whether the change instruction is received during the timer operation or the use conditions of other copy transmission change mechanisms are met, the copy transmission state is not changed. In an optional solution, no judgment may be made during the running of the first timer, and the change condition is satisfied only after the first timer expires, or in other words, the judgment is made after the first timer expires, and the state is changed. In another optional solution, even if a judgment is made during the operation of the first timer, such as the change condition is met or the change instruction is received, the change is ignored and the current copy transmission status is not modified, that is, at the timing During and after the operation of the device, the replication transmission status is not changed.

Similar to any of the foregoing embodiments, the replication transmission modification mechanism includes any of the following:

The first type is to determine the replication transmission status and/or transmission path according to the information sent by the network device for all data transmitted on the DRB;

When the network device determines that it needs to change the transmission state, it determines the first copy transmission state to be changed, and sends first information to the UE, which carries the first copy change indication and/or transmission corresponding to the first copy transmission change mechanism Path indication, the first replication change indication is used to instruct the UE to change the replication transmission state to the first replication transmission state.

Optionally, the first information may be downlink control information (English: Downlink Control Information, DCI for short) or MAC CE, or other downlink information, which is not limited in this solution.

Optionally, the first information is also used to configure the first timer for maintaining the first replication transmission state, that is, the first information is also used to configure the first timer corresponding to the first replication transmission change mechanism.

The UE receives the first information sent by the network device, where the first information carries the first copy change indication and/or the transmission path indication corresponding to the first copy transmission change mechanism, and then, according to the first copy change instruction Change the replication transmission state to the first replication transmission state, and/or determine the transmission path according to the transmission path instruction, and start the first timer for timing. It should be understood that the replication transmission status of the UE does not change during the running of the timer.

For example: the initial state of the UE is the duplication deactivated state. According to the MAC CE notified by the network device, the UE determines to change from the duplication deactivated state to the duplication activated state, that is, the first duplication transmission state, and uses

RLC entities

1, 2, and 4 to transmit duplication data. At the same time, the UE starts the first timer. During the running of the timer, the UE maintains the first copy transmission state without changing. For example, during the running of the first timer, when the UE determines that the use judgment condition of the second duplication change mechanism configured by the network is satisfied, the UE still maintains the first duplication state and ignores the second duplication change mechanism.

In another specific implementation of the solution, if the second replication transmission change mechanism is the second or third above, when the first timer expires, the first replication transmission state is changed to The second copy transmission state includes: when the first timer expires, changing the first copy transmission state to the second copy transmission state according to the copy state change rule. The meaning is that the UE first needs to obtain the new replication transmission status according to the replication status change rule, and after determining the new replication transmission status, change the status from the first replication transmission to the updated replication transmission status. The second above is just an example , It can also be the third copy transmission state.

For example: when the UE judges that the use judgment condition of the third replication transmission modification mechanism configured by the network is satisfied, the UE judges that the current first timer expires, and the UE modifies the current replication transmission state and changes to the third replication transmission state. The third copy transmission status refers to the copy transmission status determined according to the third copy transmission change mechanism mentioned above. For example, the judgment condition for the use of the third copy transmission change mechanism configured by the network device is that the DRB carries a specific QFI, or a specific data packet (such as an IR packet, I-frame packet), or when a switch command is received, or PDCP data is received When the recovery is instructed, packet-based duplication transmission is triggered. When the UE determines that this condition is met, if the currently carried packet in the bearer has an IR packet, and the first timer expires, the UE changes to the third duplication state, and only for the IR packet, the UE performs duplication transmission.

Optionally, in a specific implementation of the solution, when changing to the second copy transmission state, a second timer is started, and the second timer is a configured timer for maintaining the second copy transmission state , It may also be a timer configured or predefined for the second replication transmission change mechanism. Similarly, when changing to the third copy transmission state, the third timer is also started. The third timer is a configured timer to maintain the third copy transmission state. It can also be configured for the third copy transmission change mechanism or There is no restriction on the pre-defined timer.

S303: Perform data transmission according to the second replication transmission status.

In a specific implementation of this solution, if the second replication transmission change mechanism is for all or part of the data transmitted on the DRB, according to the carrier configured by the network device, the replication status change rule, and the path determination rule At least one, determine the replication transmission status and/or transmission path. Then the data transmission is performed according to the second copy transmission state, including: determining a transmission path for transmitting the all data or the part of the data according to the path determination rule; transferring the all data or the part of the data in the transmission Transmission on the path.

It should be noted that, for this embodiment, the duration of the timer configured for each copy transmission state or copy transmission change mechanism can be different or the same, and this solution does not impose any restriction on this.

In the method for processing replication data transmission provided by this embodiment, after the UE changes to any duplication state, the corresponding timer is started, and the duplication state change is not performed before the timer expires, even if the change is received during the running of the timer Instruct information or meet the change conditions. After the timer expires, the UE changes to the duplication state corresponding to the change mechanism that meets the change condition during the timer operation, or the UE changes to the duplication state corresponding to the change mechanism that meets the change condition after the timer runs out (in the timer After the timeout period, the UE maintains the original replication transmission state unchanged during the period when the change conditions are met. By setting a timer, the solution of maintaining a state without changing the state for a period of time has the advantage of avoiding frequent state switching, reducing the complexity of the UE and network equipment side implementation, and avoiding the problem of ping-pong handover .

FIG. 5 is a flowchart of Embodiment 4 of the method for processing copy data transmission provided by this application; as shown in FIG. 5, the method for processing copy data transmission provided by this embodiment is applied between a network device and a UE, and includes at least the following steps :

S401: When the UE is in the first replication transmission state, it is detected that the use conditions of the second replication transmission modification mechanism are met, and the priority of the second replication transmission modification mechanism is higher than that of the first replication transmission modification mechanism, according to the second replication transmission modification Mechanism to change from the first copy transmission state to the second copy transmission state.

Wherein, the first replication transmission status is a replication transmission status determined according to a first replication transmission modification mechanism; the different modification mechanisms are network device configurations or different predefined data replication transmission determination methods.

When it is detected that the UE meets the use conditions of the second replication transmission modification mechanism, the replication transmission status is not changed directly according to the second replication transmission modification mechanism, but according to the pre-defined or determined priority of the replication transmission modification mechanism , Determine whether to change, only when the priority of the second copy transmission change mechanism is higher than the priority of the first copy transmission change mechanism that determines the first copy transmission state, the first copy transmission state is changed to the second copy transmission status. If the priority of the second replication transmission modification mechanism is lower than the priority of the first replication transmission modification mechanism, even if the use conditions of the second replication transmission modification mechanism are met, the replication transmission status is not changed.

Similarly, when the UE is currently in the initial replication state, after meeting the use conditions of other replication transmission change mechanisms, the priority corresponding to the initial replication state and the priority of the replication transmission state determined by the replication transmission change mechanism are performed In comparison, if the priority of the initial replication state is higher, no change is made, otherwise it is changed to the replication transmission state determined by the replication transmission change mechanism.

In a specific implementation of the solution provided in this embodiment, there is a possibility that the UE meets the usage conditions of multiple replication transmission modification mechanisms at the same time. The following takes the usage conditions of two replication transmission modification mechanisms simultaneously as an example. While detecting that the use conditions of the third copy transmission change mechanism are met while the use conditions of the second copy transmission change mechanism are detected, the UE can change the copy transmission status in the following manner:

If the priority of the second copy transmission change mechanism is higher than the priority of the third copy transmission change mechanism, change from the first copy transmission state to the second copy according to the second copy transmission change mechanism The transmission status is determined according to the second replication transmission change mechanism when the second replication transmission status is determined.

If the priority of the second copy transmission change mechanism is lower than the priority of the third copy transmission change mechanism, change from the first copy transmission state to the third copy according to the third copy transmission change mechanism The transmission status is determined according to the third replication transmission change mechanism when the third replication transmission status is determined.

The meaning of this solution is that when the UE meets the conditions of use of multiple replication transmission modification mechanisms at the same time, it can choose to change the replication transmission status determined by the replication transmission modification mechanism with the highest priority. Based on pre-configuration or network device instructions, determine the priority of at least two replication transmission change mechanisms, or determine which mechanism corresponds to the highest priority, or determine the priority corresponding to each mechanism. According to the priority, the UE determines which mechanism to preferentially change the replication transmission state, that is, which mechanism to follow.

For example, if the network configuration first copy transmission change mechanism has a high priority, even if the UE has just completed a copy transmission state change, or even if the timer of the current copy transmission state of the UE is still running, the UE follows the first copy transmission change mechanism Change the current replication transmission status to the status indicated by the first replication transmission change mechanism.

For another example, if the network device configures the first copy transmission change mechanism with a high priority, if the change conditions corresponding to at least two copy transmission change mechanisms are met at the same time, and if it includes the conditions of the first copy transmission change mechanism, the UE follows the first copy transmission change mechanism. An indication of the replication transmission change mechanism to change the replication transmission status, otherwise, the choice depends on the UE implementation.

For another example, the network device is configured with the first copy transmission change mechanism to have the highest priority, and the second highest is the second copy transmission change mechanism. If the change conditions corresponding to at least two copy transmission change mechanisms are met at the same time, the priority of the change mechanism is followed. If the level is high or low, the UE chooses to change the replication transmission state according to the replication transmission change mechanism with high priority.

In another specific implementation of the solution provided in this embodiment, if the first replication transmission status is the replication transmission status determined according to the first replication transmission modification mechanism, and the first replication transmission modification mechanism is the aforementioned first type The replication transmission modification mechanism is to determine the replication transmission status and/or transmission path according to the information sent by the network device for all data transmitted on the data radio bearer DRB. Before this step is executed, it also includes the following steps:

When the network device determines that it needs to change the transmission state, it determines the first copy transmission state to be changed, and sends first information to the UE, which carries the first copy change indication and/or transmission corresponding to the first copy transmission change mechanism Path indication, the first replication change indication is used to instruct the UE to change the replication transmission state to the first replication transmission state. Optionally, the first information may be DCI or MAC CE, or other downlink information, which is not limited in this solution.

The UE receives the first information sent by the network device, where the first information carries the first copy change indication and/or the transmission path indication corresponding to the first copy transmission change mechanism, and then, according to the first copy change instruction Change the replication transmission state to the first replication transmission state, and/or determine the transmission path according to the transmission path indication.

Optionally, the first information can also be used to configure the priority (priority indication, or priority identifier) of the first replication transmission modification mechanism, so that in the subsequent process, if the UE meets the use of other replication transmission modification mechanisms When the conditions are met, the priority of other replication transmission modification mechanisms can be compared with the priority of the first replication transmission modification mechanism to determine whether to change the replication transmission status.

Optionally, the first information is also used to configure a first timer for maintaining the first replication transmission state. After receiving the first information sent by the network device, the UE changes the replication transmission status to First copy the transmission state and start the first timer. The meaning of this scheme is that a combination of timer and priority can be used to determine under what circumstances the replication transmission status can be changed. In a specific application process of this solution, during the running of the first timer, if the UE meets the use conditions of the second replication transmission change mechanism, the replication transmission state is not changed, and after the first timer runs out According to the priority of the first copy transmission change mechanism and the priority of the second copy transmission change mechanism, determine whether to change the copy transmission status. Generally speaking, if the priority of the second copy transmission change mechanism is higher, the first The copy transmission state is changed to the second copy transmission state, otherwise no change is made.

Optionally, in a specific implementation, only the high-priority replication transmission change mechanism can be configured with a timer, and after the replication transmission state is changed according to the high-priority replication transmission change mechanism, the configured timer is started, During the running of the timer, keep in the copy transmission state, and achieve the priority purpose through the timer.

Optionally, you can also choose to change the replication transmission status according to the change rule with higher priority during the time when the timer is running. It can be set according to different actual conditions according to whether the timer has priority or priority. There is no restriction on this program.

In another specific implementation of the solution provided in this embodiment, if the second replication transmission modification mechanism is the aforementioned second or third replication transmission modification mechanism, that is, for part of the data transmitted on the data radio bearer DRB or For all data, the replication transmission status and/or the transmission path are determined according to at least one of the carrier configured by the network device, the replication status change rule, and the path determination rule. Then, according to the replication status change rule, the first replication transmission status is changed to the second replication transmission status.

In a specific implementation of this solution, when it is determined that the priority of the second replication transmission change mechanism is higher than the priority of the first replication transmission change mechanism, the second replication transmission state can be determined according to the replication status change rule, and then the first The first copy transmission state is changed to the second copy transmission state.

Optionally, in another specific implementation of the solution, when changing to the second copy transmission state, a second timer is started, and the second timer is a configured timing for maintaining the second copy transmission state The timer may also be a timer configured or predefined for the second replication transmission change mechanism. Similarly, when changing to the third copy transmission state, the third timer is also started. The third timer is a configured timer to maintain the third copy transmission state. It can also be configured for the third copy transmission change mechanism or There is no restriction on the pre-defined timer.

S402: Perform data transmission according to the second copy transmission state.

After changing the replication transmission state, the UE adopts the second replication transmission state to transmit the data carried on the DRB.

Optionally, in a specific implementation of the solution, if the second replication transmission change mechanism is for all or part of the data transmitted on the DRB, according to the carrier, replication status change rules, and path configured by the network device Determine at least one of the rules to determine the replication transmission status and/or transmission path. Then the data transmission is performed according to the second copy transmission state, including: determining a transmission path for transmitting the all data or the part of the data according to the path determination rule; transferring the all data or the part of the data in the transmission Transmission on the path.

It should be noted that for this embodiment, the priority can be configured for each replication transmission state or replication transmission change mechanism, or only one or several replication transmission change mechanisms can be configured with priority. This solution does not do this. limit.

The processing method for copy data transmission provided in this embodiment configures different priorities for different copy transmission change mechanisms or copy transmission states. In an optional implementation manner, for a solution based entirely on network equipment, and based on The schemes of UE and network equipment are distinguished, and high-priority processing strategies are given to the replication transmission change mechanism with a higher degree of network equipment participation. The advantage is to make the UE follow the network's decision as much as possible, so that the UE behavior is as affected as possible. Controlled on the network side to avoid the situation where the network judges the UE behavior incorrectly.
