Description
Technical Field

Background
Fig. 1 is a schematic diagram of data radio bearer repeat transmission. After configuring a repeated transmission mechanism to a terminal through an RRC (Radio Resource Control) message, the terminal adds another RLC (Radio Link Control, Radio Link layer Control protocol) entity and a logical channel to a current DRB (Data Radio Bearer ), where a pdcp (packet Data Convergence protocol) entity of the DRB repeatedly transmits Data packets to be transmitted on two links; one link is the original RLC entity and the other link is the newly added RLC entity. The repeated transmission mechanism can greatly improve the reliability of air interface transmission and shorten the transmission delay.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, an embodiment of the present invention provides a method for processing repeated transmission, which is applied to a network node of a packet data convergence protocol PDCP entity provided with a target data radio bearer DRB, where the PDCP entity is connected to at least two transmission links, and the method includes:
In the above embodiments of the present invention, the activated or deactivated status of the repeated transmission is allowed to be exchanged between at least two transmission links (including one primary link and at least one secondary link) connected to the same PDCP entity.
Specifically, when the repeated transmission of the target DRB is in a certain state (a repeated transmission activated state or a deactivated state), if one of at least two transmission links connected to the same PDCP entity (a first transmission link) determines to activate or deactivate the repeated transmission, the first transmission link notifies the terminal of a signaling for activating or deactivating the repeated transmission of the target DRB through a MAC CE (media access control layer control unit), the first transmission link also notifies the PDCP entity of the repeated transmission state of the target DRB, and then the PDCP entity notifies the network node corresponding to the other transmission links (i.e., other transmission links except the first transmission link) that need to participate in the repeated transmission of the target DRB.
As an embodiment, the network node corresponding to the first transmission link and the network node of the PDCP entity with the target DRB are the same network node, and in a case that the network node corresponding to the first transmission link and the network node of the PDCP entity with the target DRB are the same network node, step 201 includes:
and receiving the repeated transmission state of the target DRB, which is sent by the network node corresponding to the first transmission link through the interlayer internal interface.
As another embodiment, the network node corresponding to the first transmission link and the network node of the PDCP entity with the target DRB are different network nodes, and in case that the network node corresponding to the first transmission link and the network node of the PDCP entity with the target DRB are different network nodes, step 201 includes:
and receiving the repeated transmission state of the target DRB, which is sent by the network node corresponding to the first transmission link through an external standard interface.
As yet another example, step 202 includes:
and sending the repeated transmission state of the target DRB to network nodes corresponding to other links except the first transmission link through an external standard interface. For example, the external standard interface is an F1 interface or an Xn interface.
For example, as shown in fig. 3, the manner in which the network node provided with the PDCP entity sends the duplicate transmission status to other network nodes (i.e., network nodes corresponding to other links participating in the duplicate transmission except the first transmission link) may be: and sending a downlink data frame, wherein the sent downlink data frame can carry a 1-bit indication, and the 1-bit indication is used for indicating activation or deactivation of repeated transmission. For example, "0" indicates activation of repeated transmission, and "1" indicates deactivation of repeated transmission; alternatively, "1" indicates activation of the repeated transmission and "0" indicates deactivation of the repeated transmission.
For another example, as shown in fig. 4, the manner for the other network nodes (i.e. the network nodes corresponding to the other links participating in the repeated transmission except the first transmission link) to send the repeated transmission status to the network node provided with the PDCP entity may be: and sending a downlink data transmission state frame, wherein the downlink data transmission state frame carries a 1-bit indication, and the 1-bit indication is used for indicating activation or deactivation of repeated transmission. For example, "0" indicates activation of repeated transmission, and "1" indicates deactivation of repeated transmission; alternatively, "1" indicates activation of the repeated transmission and "0" indicates deactivation of the repeated transmission.
It should be noted that the network node provided with the PDCP entity of the target DRB includes a master node (which may be referred to as MeNB or MgNB or MN) in the dual connectivity mode and a central unit (gNB-CU) entity in a CU-DU (central unit-distributed unit) mode.
In order to more clearly describe the processing method of the repeated transmission provided by the embodiment of the present invention, the following describes in detail with reference to a plurality of examples.
Example one: as shown in FIG. 5, the information interaction between different nodes under the dual-connection architecture
Step 21, the master node (MeNB or MgNB) determines to activate or deactivate the repeated transmission operation carried by the target DRB according to the radio channel condition, the load condition, the RRM algorithm for radio resource management, etc. At this time, the master node transmits a corresponding command indication to the terminal through the MAC CE.
Step 22, after receiving the request, the terminal executes the operation of activating or deactivating the repeated transmission of the target DRB bearer in the uplink direction;
it should be noted that after the repeated transmission is activated, the uplink data (PDCP protocol data unit PDU) will be duplicated and transmitted through the primary link (configured by RRC signaling, here assumed to be the UE to MN link) and the secondary link (here assumed to be the UE to SN link) (there may be more than one secondary link), respectively. On the contrary, if the repeated transmission is deactivated, the uplink data (PDCP PDU) stops being copied and is only transmitted through the main link.
In step 23, the PDCP entity of the primary node (MeNB or MgNB) transmits a duplicate transmission activation or deactivation status to the secondary node (SgNB or SeNB).
Example two: as shown in FIG. 6, under CU/DU architecture, information interaction between different DUs
Step 31, the main link (distribution unit 1) determines to activate or deactivate the repeated transmission operation of the target DRB bearer according to the radio channel condition, the load condition, the RRM algorithm, and the like. At this time, a corresponding command is instructed to be transmitted to the terminal through the MAC CE.
Step 32, after receiving the request, the terminal executes the operation of activating or deactivating the repeated transmission of the target DRB bearer in the uplink direction;
it should be noted that after the repeated transmission is activated, the uplink data (PDCP PDU) is duplicated and transmitted via the primary link (configured by RRC signaling, here assumed to be the terminal to distribution unit 1 link) and the secondary link (here assumed to be the terminal to distribution unit 2 link) (there may be more than one secondary link), respectively. On the contrary, if the repeated transmission is deactivated, the uplink data (PDCP PDU) stops being copied and is only transmitted through the main link.
Step 33: the main link (distribution unit 1) sends a duplicate transmission activation or deactivation status to the concentration unit (gNB-CU) entity.
It should be noted that, step 22 and step 23 do not have a sequential order, and may be executed simultaneously or sequentially, and are not specifically limited herein.
After the central unit entity receives the command, its PDCP entity transmits a duplicate transmission activation or deactivation command to the distribution unit 2 node (gNB-DU2), step 34.
In summary, in the above embodiments of the present invention, the activation or deactivation states of the repeated transmission of the target DRB are mutually exchanged between at least two transmission links connected by the PDCP entity, so that each transmission link participating in the repeated transmission of the target DRB maintains consistency of the repeated transmission states, thereby avoiding signaling redundancy and contradictory signaling contents, and simplifying the processing procedure of the terminal.
As shown in fig. 7, an embodiment of the present invention further provides a method for processing repeated transmission, where the method is applied to a network node of a packet data convergence protocol PDCP entity provided with a target data radio bearer DRB, where the PDCP entity is connected to at least two transmission links, and the method includes:
In the above embodiments of the present invention, when the target DRB is configured in the duplicate transmission mode, the network entity of the PDCP entity provided with the target DRB selects one of the transmission links, the selected transmission link is used as a main link, and at any time, only the network node corresponding to the main link is allowed to dynamically activate or deactivate the duplicate transmission operation through the MAC CE.
It should be noted that, the network nodes corresponding to the other transmission links except the selected transmission link in the at least two transmission links prohibit the activation or deactivation operation for performing the repeated transmission of the target DRB.
Because only one transmission link in the plurality of transmission links can be used for activating or deactivating the repeated transmission of the target DRB, the consistency of the repeated transmission state of each transmission link participating in the repeated transmission of the target DRB can be kept, so that signaling redundancy and contradictory signaling contents are avoided, and the processing process of the terminal is simplified.
Optionally, in the above embodiment of the present invention, the method further includes:
the network node corresponding to the selected transmission link receives auxiliary information sent by network nodes corresponding to other transmission links except the selected transmission link in the at least two transmission links, where the auxiliary information includes: a load condition of the network node and/or a channel quality of the network node;
and the network node corresponding to the selected transmission link determines whether to activate or deactivate the repeated transmission of the target DRB according to the auxiliary information.
As shown in fig. 8, the manner of sending the auxiliary information to the network node corresponding to the selected transmission link by other network nodes (i.e., network nodes corresponding to other transmission links except the selected transmission link) includes: and sending a downlink data transmission state frame, wherein the downlink data transmission state frame carries a 1-bit indication, and the 1-bit indication is used for indicating whether the current load of the network node is overweight or lighter.
In summary, in the above embodiments of the present invention, only one transmission link is selected for performing the activation or deactivation operation of the repeated transmission of the target DRB, so that each transmission link participating in the repeated transmission of the target DRB maintains the consistency of the repeated transmission state, thereby avoiding signaling redundancy and conflicting signaling contents, and simplifying the processing procedure of the terminal.
