This application claims the priority of Chinese Patent Application No. 201910090488.4 filed in China on January 30, 2019, the entire content of which is incorporated herein by reference.

Technical field

The present disclosure relates to the field of communication technology, and in particular to a method, device and equipment for sending and receiving information.

Background technique

In the wireless access system, the terminal can communicate with the access network through two or more cell groups. This configuration can improve the reliability of data transmission and the throughput of data transmission. Different cell groups have different cell group IDs (Cell Group ID). The cell group whose Cell Group ID is 0 is called the master cell group (Master Cell Group, MCG), and the remaining cell groups are called the secondary cell group (Secondary Cell Group, SCG).

As shown in Figure 1, in E-UTRA and NR systems, RRC (Radio Resource Control) configuration information mainly includes these three types of parameters: measurement configuration, radio bearer configuration information, and cell group configuration information. Among them, the measurement configuration information is used to specify which measurements the network side requires the terminal to perform; the radio bearer configuration information is used to specify which bearers the terminal should configure, and how these bearers should configure PDCP layer and SDAP layer resources; and the cell group configuration information is used to specify How to configure physical layer, MAC layer and RLC layer resources.

Dual connectivity means that the same user terminal is connected to two radio access network nodes at the same time, one of which is a master node (Master Node, MN) and the other node is a secondary node (Secondary Node, SN). Figure 1 shows the internal structure of the Next Generation-Radio Access Network (NG-RAN) dual-connection system in the radio access network. The solid lines represent data bearers.

According to related technologies, when configuring dual connections for a user terminal, which node generates the RRC configuration information on the terminal side corresponding to which node of the radio access network the network side module is located. For example, if the network side wants to instruct the user terminal to perform a measurement and report the measurement result to the RRC layer of the master node, the corresponding measurement configuration information should be generated by the master node. For another example, if the network side wants to instruct the user terminal to establish an SCG bearer that terminates at the master node, then the corresponding PDCP (Packet Data Convergence Protocol) layer and SDAP (Service Data Adaptation Protocol, service data adaptation protocol) layer The bearer configuration information should be included in the radio bearer configuration information generated by the master node, and the corresponding RLC (Radio Link Control, radio link control) layer bearer configuration information should be included in the cell group generated by the slave node Configuration information.

According to related technologies, in RRC signaling, the measurement configuration information, radio bearer configuration information, and cell group configuration information generated by the master node and the slave node are located on different code bits. The RRC signaling in the related technology only supports simple incremental configuration operations: according to the protocol specification, some parameters are suitable for incremental configuration. If the parameter in the configuration information does not appear, its value should continue to be stored in the user terminal. The parameter value of the same code point.

According to related technologies, the cell group configuration must include the Cell Group ID information of the cell group. The cell group whose Cell Group ID is 0 is the master cell group (Master Cell Group, MCG), and the cell group whose Cell Group ID is not 0 is the secondary cell group (Secondary Cell Group, SCG). Air interface RRC signaling in related technologies does not support the modification of the Cell Group ID of a cell group by incremental reconfiguration. It can only be modified through comprehensive reconfiguration, which not only has the serious drawbacks of air interface signaling, but also causes The unnecessary bottom layer reset and synchronous reconfiguration operations are eliminated, and the delay of data transmission interruption is significantly increased.

In addition, the Xn interface signaling in the related technology does not support the interchange of the dual-connected primary node and secondary node in an incremental reconfiguration manner. According to the related technology, MCG must be controlled by the master node, and SCG must be controlled by the auxiliary node, which means that the Xn interface in the related technology does not support the exchange of MCG and SCG, which is equivalent to not supporting incremental reconfiguration Modify the Cell Group ID of a cell group in the following way.

2) CU/DU separation structure

In the New Air Interface (NR) and similar systems, a logical radio access network node (RAN node) can be further divided into a central unit (Central Unit, CU) and one or more distributed units (Distributed Unit, DU) This structure is called "CU/DU split (CU/DU split)".

Figure 2 shows the structure of NR CU/DU separation. The solid line represents the data channel, including bearer and inter-node signaling.

Similar to the dual connection scenario, in the CU/DU separation scenario, in which wireless access network node the network side module is located, the RRC configuration information on the terminal side corresponding to it is generated by which node. Taking the NR system as an example, the cell group configuration refers to the configuration of the RLC layer, the MAC layer, and the physical layer. In the CU/DU separation scenario, they are all located inside the DU. Therefore, the cell group configuration information must also be generated by the DU. However, the radio resource management function of the terminal is controlled by the CU. The reconfiguration process of changing the Cell Group ID of a cell group can only be initiated by the CU, and then informs the DU through F1 interface signaling, so that the DU generates and feeds back the cell group configuration information. Finally, the information is included in the RRC reconfiguration message and sent to the user terminal. Similar to the air interface RRC signaling, the F1 interface signaling in the related technology does not support the modification of the Cell Group ID of a cell group by incremental reconfiguration. It can only be operated by releasing the context and then adding the context, which destroys the data. Continuity of transmission.

In summary, the current wireless access technology supports incremental configuration, that is, between the network and the terminal, and between different network nodes, new configurations can be encoded, decoded, and applied based on the current configuration. However, the current technology does not support the operation of changing the Cell Group ID, for example, it does not support the reconfiguration of the MCG to the SCG. If the Cell Group ID of a cell group needs to be changed between the network and the terminal or between different network nodes, it can only use it as a new cell group to encode, decode, and apply new configurations. This not only increases the signaling load and operational complexity, but may also cause unnecessary user plane data transmission interruption and network-side configuration failures.

Step 1: The gNB-CU decides to initiate an intra-gNB handover process to change the current MCG to SCG and the current SCG to MCG. The current MCG is using the physical resources inside gNB-DU1, and the current SCG is using the physical resources inside gNB-DU2.

Step 2: The gNB-CU sends a user terminal context modification request message (such as a third interface message) to gNB-DU1, which contains an instruction to reconfigure the source MCG to the target SCG (such as the fifth instruction information).

Step 3: The gNB-DU1 generates the cell group configuration information of the target SCG after the handover, which contains the cell group identification information of the source MCG to indicate that the configuration information is incremental configuration information based on the source MCG configuration information.
