This application claims the priority of Chinese Patent Application No. 201910063457.X filed in China on January 23, 2019, the entire content of which is incorporated herein by reference.

Technical field

The present disclosure relates to the field of communication technologies, and in particular to a method, device and equipment for configuring the state of a secondary cell.

Background technique

In the LTE system, the concept of CA (Carrier Aggregation) is introduced, that is, the resources of multiple cells can be used to provide services for one UE (User Equipment, or terminal). Among them, Pcell is the primary cell, and Scell is the secondary cell. The activation and deactivation of the Scell is achieved through MAC CE (Medium Access Control CE, Media Access Control Unit).

In order to further improve system performance, Rel-15 considers the enhancement of CA, that is, while adding Scell, the state of Scell can be set through RRC (Radio Resource Control) message, whether it is active, dormant or inactive. The method is also applicable to base stations under 5G systems. At the same time, in the 5G system and LTE system, a separate architecture of CU (Centralized Unit)/DU (Distributed Unit) is introduced. CU mainly includes non-real-time wireless high-level protocol stack functions, and also supports part of the core Network function sinking and deployment of edge application services; DU mainly deals with physical layer functions and layer 2 functions of real-time requirements.

As shown in 1 is an architecture diagram on the RAN (Radio Access Network) side that includes CU/DU separation. The CU/DU separation method on the RAN side is divided into high-level separation and low-level separation. Among them, the high-level separation scheme is RRC, SDAP (Service Data Adaptation Protocol) and PDCP (Packet Data Convergence Protocol) in CU; RLC (Radio Link Control, Radio Link Control), MAC And the physical layer and RF (radio frequency) are in the DU.

In Rel-15, CA has been enhanced. When adding Scell, the UE will be notified of the added Scell status. The message structure is included in the air interface message RRC Reconfigure. According to the newly added IE sCellState-r15, the UE learns the status of the Scell configured on the network side.

According to protocols in related technologies, Scell configuration information, including Scellstate IE, is included in the message structure corresponding to the underlying configuration, namely Cell Group Config. The message structure is generated by DU.

However, when the Scell is added, the DU does not have information related to the signal quality of the cell, and it is impossible to determine whether the cell state should be set to be activated, dormant, or deactivated. Therefore, in a scenario where the CU/DU are separated, it is impossible to support the setting of the cell state when adding the Scell.

Step 3. The CU decides to add cell 2 as Scell according to the measurement result in the RRC message;

Step 4. The CU sends a UE context modification request (terminal context modification request) message to increase the Scell. The CU also sends the measurement results reported by the UE to the DU;

Step 5: The DU decides that the status of the newly added cell is active according to the received measurement result and the saved UE context. DU configures the corresponding message structure in the bottom layer, namely CellGroupConfigure (cell group configuration), sets the state of the newly added Scell to active, and includes it in the UE context modification response message;

Step 6. The CU generates an RRC reconfiguration RRC message, which is included in the DL RRC message and sent to the DU;
