detailed description

To make the technical problems, technical solutions, and advantages to be solved by the present disclosure clearer, the following will describe in detail with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 2, the embodiment of the present disclosure provides a processing method for repeated transmission, which is applied to a network node provided with a PDCP entity of a packet data aggregation protocol of a target data wireless bearer DRB. Treatment methods include:

Step 201: Receive a repeated transmission state of a target DRB sent by a network node corresponding to the first transmission link of the at least two transmission links, where the repeated transmission state of the target DRB includes an activated state or a deactivated state;

Step 202: Send the repeated transmission status of the target DRB to a network node corresponding to other transmission links except the first transmission link in the at least two transmission links.

In the above embodiments of the present disclosure, at least two transmission links (including a primary link and at least one secondary link) connected to the same PDCP entity are allowed to exchange the activation or deactivation status of repeated transmission.

Specifically, when the repeated transmission of the target DRB is in a certain state (repetitive transmission activation state or deactivation state), if one of at least two transmission links connected to the same PDCP entity (set as the first transmission Link) decides to activate or deactivate the repeated transmission. At this time, the first transmission link notifies the terminal of the signaling of activation or deactivation of the repeated transmission of the target DRB through the MAC (Media Intervention Control Layer Control Unit). A transmission link also notifies the PDCP entity of the repeated transmission status of the target DRB, and then the PDCP entity notifies the repeated transmission status of the target DRB to other transmission links that need to participate in the repeated transmission (that is, the at least two transmission links Network nodes corresponding to other transmission links except the first transmission link).

As an example, the network node corresponding to the first transmission link and the network node of the PDCP entity set with the target DRB are the same network node, and the network node corresponding to the first transmission link and the PDCP with the target DRB set When the network nodes of the entities are the same network node, step 201 includes:

As another example, the network node corresponding to the first transmission link and the network node of the PDCP entity set with the target DRB are different network nodes, and the network node corresponding to the first transmission link and the network node with the target DRB set When the network node of the PDCP entity is a different network node, step 201 includes:

As yet another example, step 202 includes:

Sending the repeated transmission status of the target DRB to the network node corresponding to the other links except the first transmission link through an external standard interface. For example, the external standard interface is the F1 interface or Xn interface.

For example, as shown in FIG. 3, the network node provided with the PDCP entity may send the repeated transmission status to other network nodes (that is, network nodes corresponding to links other than the first transmission link that participate in the repeated transmission) as: : Send a downlink data frame. The sent downlink data frame may carry a 1-bit indication, which is used to indicate activation or deactivation of repeated transmission. For example, "0" indicates that repeated transmission is activated, and "1" indicates that repeated transmission is deactivated; or, "1" indicates that repeated transmission is activated, and "0" indicates that repeated transmission is deactivated.

For another example, as shown in FIG. 4, other network nodes (that is, network nodes corresponding to links other than the first transmission link that participate in the repeated transmission) can send the repeated transmission status to the network node provided with the PDCP entity. It is: sending a downlink data transmission status frame, and carrying a 1-bit indication in the downlink data transmission status frame, where the 1-bit indication is used to indicate activation or deactivation of repeated transmission. For example, "0" indicates that repeated transmission is activated, and "1" indicates that repeated transmission is deactivated; or, "1" indicates that repeated transmission is activated, and "0" indicates that repeated transmission is deactivated.

It should be noted that the network node of the PDCP entity provided with the target DRB includes the master node in dual connection mode (may be called MeNB or MgNB or MN), and the centralized unit in CU-DU (centralized unit-distributed unit) mode (gNB-CU) entity.

In order to more clearly describe the processing method for repeated transmission provided by the embodiments of the present disclosure, the following describes in detail with reference to multiple examples.

Example 1: As shown in Figure 5, the information exchange between different nodes in a dual connection architecture

Step 21: The master node (MeNB or MgNB) decides to activate or deactivate the repeated transmission operation carried by the target DRB according to the radio channel conditions, load status, radio resource management RRM algorithm, etc. At this time, the master node transmits the corresponding command instruction to the terminal through the MAC CE.

Step 22: After receiving, the terminal will perform repeated transmission activation or deactivation operations in the uplink direction of the target DRB bearer;

It should be noted that after repeated transmission is activated, the uplink data (PDCP protocol data unit PDU) will be copied, respectively, through the main link (configured by RRC signaling, here assumed to be: UE to MN link), and the auxiliary Links (here assumed to be: UE to SN links) (more than one auxiliary link) can be transmitted. On the contrary, if the repeated transmission is deactivated, the upstream data (PDCP) will stop copying and only transmit through the main link.

Step 23: The PDCP entity of the master node (MeNB or MgNB) transmits the repeated transmission activation or deactivation state to the secondary node (SgNB or SeNB).

Example 2: As shown in Figure 6, under the CU / DU architecture, information exchange between different DUs

In step 31, the main link (distribution unit 1) decides to activate or deactivate the repeated transmission operation of the target DRB bearer according to the radio channel conditions, load conditions, radio resource management RRM algorithm, etc. At this time, the corresponding command will be transmitted to the terminal through the MAC CE.

Step 32: After receiving, the terminal will perform repeated transmission activation or deactivation operations in the uplink direction of the target DRB bearer;

It should be noted that after repeated transmission is activated, the uplink data (PDCP PDU) will be copied through the primary link (configured by RRC signaling, here it is assumed to be: the link from the terminal to the distribution unit 1), and the secondary link Way (assumed here: the link from the terminal to the distribution unit 2) (may have more than one auxiliary link) for transmission. On the contrary, if the repeated transmission is deactivated, the upstream data (PDCP) will stop copying and only transmit through the main link.

Step 33: The main link (distribution unit 1) sends the repeated transmission activation or deactivation status to the centralized unit (gNB-CU) entity.

It should be noted that step 22 and step 23 have no sequential order, and can be executed simultaneously or sequentially, which is not specifically limited here.

In step 34, after receiving the centralized unit entity, its PDCP entity transmits a repeated transmission activation or deactivation command to the distribution unit 2 node (gNB-DU2).

In summary, in the above embodiments of the present disclosure, at least two transmission links connected by the PDCP entity exchange the activation or deactivation status of the repeated transmission of the target DRB, so that each transmission chain participating in the repeated transmission of the target DRB The channel maintains the consistency of the repeated transmission state, thereby avoiding signaling redundancy and contradictory signaling content, simplifying the terminal's processing procedure.

As shown in FIG. 7, an embodiment of the present disclosure also provides a processing method for repeated transmission, which is applied to a network node provided with a packet data aggregation protocol PDCP entity of a target data wireless bearer DRB, and the PDCP entity connects at least two transmission links. The processing method includes:

Step 701, in the case that the target DRB is configured in the repeated transmission mode, select one transmission link from the at least two transmission links, and the network node corresponding to the selected transmission link is used for repeated transmission of the target DRB Activate or deactivate the operation.

In the above-mentioned embodiment of the present disclosure, in the case where the target DRB is configured in the repetitive transmission mode, the network entity provided with the PDCP entity of the target DRB selects one of the transmission links, and the selected transmission link serves as the main link. At this time, only the network node corresponding to the main link is allowed to dynamically activate or deactivate the repeated transmission operation through the MAC CE.

It should be noted that the network node corresponding to the other transmission link except the selected transmission link in the at least two transmission links prohibits activation or deactivation operations for repeated transmission of the target DRB.

Since only one of the multiple transmission links can be used to activate or deactivate the repeated transmission of the target DRB, each transmission link participating in the repeated transmission of the target DRB can maintain the consistency of the repeated transmission state In order to avoid signaling redundancy and conflicting signaling content, the terminal's processing procedure is simplified.

Optionally, in the above embodiments of the present disclosure, 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 in the at least two transmission links except the selected transmission link, the auxiliary information includes: the network Node load status and / or channel quality of network nodes;

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 in which other network nodes (ie, network nodes corresponding to other transmission links except the selected transmission link) send auxiliary information to the network node corresponding to the selected transmission link includes: sending a downlink The data transmission status frame carries a 1-bit indication in the downlink data transmission status frame, and the 1-bit indication is used to indicate whether the current load of the network node is too heavy or light.

In summary, in the above embodiments of the present disclosure, by selecting only one transmission link for the activation or deactivation operation of the repeated transmission of the target DRB, each transmission link participating in the repeated transmission of the target DRB maintains the state of repeated transmission Consistency, thereby avoiding signaling redundancy and conflicting signaling content, simplifying the terminal's processing procedure.
