And coverage requirements, which are often referred to as multiple connections. In the Long Term Evolution (LTE) network system, commonly used multi-connection methods include carrier aggregation, coordinated multi-point (CoMP), and dual connectivity.

In the dual connectivity (DC) transmission mode, the protocol architecture of the duplicate data transmission mode is as shown in FIG. 1A, and the protocol architecture adopts a protocol architecture that separates the bearer bearer; for uplink and downlink, the packet data control protocol The Packet Data Convergence Protocol (PDCP) entity is located in a certain Cell Group (CG) base station (a serving cell group MCG base station controlled by a primary base station or a serving cell group SCG base station controlled by a secondary base station). The PDCP entity copies the PDCP Protocol Data Unit (PDU) into the same two copies, for example, one is a PDCP PDU, and the other is a Duplicated PDCP PDU. The two PDCP PDUs pass through the RLC layer entity and the MAC layer entity of different CG base stations. Then, the MAC address entity and the RLC layer entity corresponding to the terminal (downlink) or the base station (uplink) are finally transmitted to the PDCP layer entity, and the PDCP layer entity detects that the two PDCP PDUs are in the same version, that is, discard one of them. Submit the other to the high level entity. The one bearer that connects the two RLC entities and the MAC entity respectively is called a split bearer, and if the PDCP entity is located at the MCG base station, it is an MCG split bearer, and if the PDCP entity is located at the SCG base station, it is an SCG split bearer.

As shown in FIG. 1B, the wireless communication system 100 can include one or more network devices 101, one or more terminals 103, and a core network 115. among them:

The network device 101 can be a base station, and the base station can be used for communicating with one or more terminals, and can also be used for communicating with one or more base stations having partial terminal functions (such as a macro base station and a micro base station, such as an access point, Communication between). The base station may be a Base Transceiver Station (BTS) in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or may be an evolved base station in an LTE system (Evolutional Node B). , eNB), and base stations in 5G systems, new air interface (NR) systems. In addition, the base station may also be an Access Point (AP), a TransNode (Trans TRP), a Central Unit (CU), or other network entity, and may include some or all of the functions of the above network entities. .

Terminals 103 may be distributed throughout wireless communication system 100, either stationary or mobile. In some embodiments of the present application, the terminal 103 may be a mobile device, a mobile station, a mobile unit, an M2M terminal, a wireless unit, a remote unit, a user generation. Management, mobile client, and more.

In particular, network device 101 can be used to communicate with terminal 103 over wireless interface 105 under the control of a network device controller (not shown). In some embodiments, the network device controller may be part of the core network 115 or may be integrated into the network device 101. Specifically, the network device 101 can be configured to transmit control information or user data to the core network 115 through a blackhaul interface 113 (such as an S1 interface). Specifically, the network device 101 and the network device 101 can also communicate with each other directly or indirectly through a blackhaul interface 111 (such as an X2 interface).

It should be noted that the wireless communication system 100 shown in FIG. 1B is only for the purpose of more clearly explaining the technical solutions of the present application, and does not constitute a limitation of the present application. Those skilled in the art may know that with the evolution of the network architecture and new services, The appearance of the scenario, the technical solution provided by the present application is equally applicable to similar technical problems.

The related art related to the present application will be described below.

At present, in the fifth-generation mobile communication technology (5th-Generation, 5G) and the new radio (NR) system, it is proposed to use the packet data convergence protocol (Packet) for the carrier aggregation technology to support data duplication (Data Duplication). The data replication function of the Data Convergence Protocol (PDCP) layer entity transmits the duplicated PDCP Protocol Data Unit (PDCP PDU) to two Radio Link Control (RLC) layer entities ( The two RLC layer entities respectively have different logical channels), and finally ensure that the copied PDCP PDUs can transmit data on different physical layer aggregate carriers.

However, in the DC scenario, the master node (MN) and the slave node (SN) can send MAC CEs. When a data replication bearer is established/released, it affects the format of the MAC CE. If a Master Cell Grpup bearer (MCG bearer) is in the data replication mode, a corresponding bit bit should appear on the MAC CE, otherwise it is not. This is the change of the MAC CE format. The problem here is that for the MCG bearer, since it is independent of the SN, the SN may not know the presence or absence of the MCG bearer, so it is not known whether the MAC CE format should be changed. Considering that the RRC signaling of the bearer setup/release is sent by the MN to the User Equipment (UE), and the transmission of the signaling takes time, how the SN controls the transmission of the MAC CE to avoid the misunderstanding of the UE is required to be solved. The problem. The misunderstanding here is:

(1) The RRC signaling of the bearer setup/release sent by the MN to the UE has not been correctly received, and the SN has already transmitted the MAC CE according to the new format.

(2) The RRC signaling of the bearer setup/release sent by the MN to the UE has been correctly received, and the SN still transmits the MAC CE according to the old format.

In one possible example, the method further comprises: the second network device receiving third signaling from the terminal; the second network device transmitting updated MAC CE signaling to the terminal.

It can be seen that, in this example, the second network device can resume sending the updated MAC CE signaling by receiving the third signaling from the terminal, so as to ensure the consistency of the scheduling bearer between the second network device and the terminal.

In a possible example, the third signaling is used to indicate that the second network device receives the random access request initiated by the terminal, and sends the updated MAC CE signaling to the terminal after successful completion. .

In a possible example, the second network device updates the sending of the medium access control layer control unit MAC CE signaling according to the first signaling, including: the second network device according to the first signaling The MAC CE signaling is cancelled to be sent to the terminal, and the format of the MAC CE signaling is updated.

The transmission of the command can prevent the second network device from sending MAC CE signaling to the terminal during the period in which the target bearer is updated, causing the bearer scheduling to be inconsistent, which is beneficial to improving the network device between the dual connectivity transmission system and the terminal. The consistency of the scheduling bearer.
