Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for configuring a secondary cell state.
Background
In L TE system, a concept of CA (Carrier Aggregation) is introduced, that is, resources of multiple cells can be utilized to provide service for one UE (User Equipment or terminal), where Pcell is a primary cell and Scell is a secondary cell.
In order to further improve the system performance, Rel-15 considers CA enhancement, that is, while adding Scell, the state of Scell can be set through RRC (Radio Resource Control) message, and is an active, dormant or inactive state, and the method is also applicable to a base station under a 5G system, meanwhile, in the 5G system and L TE system, a structure with CU (Centralized Unit)/DU (Distributed Unit) separation is introduced, CU mainly includes a non-real-time Radio higher layer protocol stack function, and also supports the deployment of part of core network function sinking and edge application services, and DU mainly handles the layer 2 function of physical layer function and real-time requirement.
As shown in FIG. 1, an architecture diagram of a RAN (Radio Access Network) side including CU/DU separation is shown, and the CU/DU separation mode of the RAN side is divided into a high layer separation and a low layer separation, wherein the high layer separation scheme includes that RRC, SDAP (Service Data Adaptation Protocol) and PDCP (Packet Data Convergence Protocol) are located in a CU, R L C (Radio L ink Control), MAC and physical layers, and RF (Radio frequency) are located in a DU.
In Rel-15, CA was enhanced. And when the Scell is added, informing the UE of the state of the added Scell, wherein a message structure is contained in an air interface message RRC reconfiguration, and the UE acquires the state of the Scell configured on the network side according to the newly added IE sCellState-r 15.
According to the current protocol, the configuration information of the Scell, including the Scellstate IE, is contained in the message structure corresponding to the underlying configuration, i.e., the Cell Group Config. The message structure is generated by the DU.
However, when the Scell is added, the DU has no information about the signal quality of the cell yet, and it cannot be determined whether the cell state should be set to be active, dormant, or deactivated. Therefore, in the CU/DU separation scenario, the cell state cannot be supported when adding Scell.

That is, the CU directly provides the initial state information of the secondary cell to the DU, where the CU adds the secondary cell and carries the state information of the secondary cell during the process of establishing or modifying the UE context of the DU.
In a specific implementation, as shown in fig. 3, a network device (e.g., a base station) served by the UE is a CU/DU separation architecture, and the current Pcell of the UE is a cell 1. In order to better provide service for the UE, the network side decides to add a cell2 as the Scell of the UE. The CU decides whether the cell status of the added Scell is active or dormant or deactivated. The specific process comprises the following steps:
step 1, the connected UE sends RRC message containing measurement result to DU;
step 2, DU transmits the RRC message to CU;
step 3, the CU determines to add a cell2 as a Scell according to the measurement result in the RRC message, and simultaneously determines to set the initial state of the Scell as an Active state;
and step 4, the CU sends a UE context modification request message to add the Scell. The CU informs the DU that the initial state of the Scell is Active;
step 5, the DU sets the state of the newly added Scell as Active in a message structure corresponding to the bottom layer configuration, i.e. in CellGroupConfigure (cell group configuration), according to the instruction of the CU, and includes the Active Scell in a UE context modification response message.
Step 6, the CU generates an RRC message of RRC reconfiguration, and the RRC message is contained in D L RRCmessage and is sent to the DU;

The secondary cell states here include: activated, deactivated, or dormant.
In a specific implementation, as shown in fig. 4, a serving base station of the UE is a CU/DU separation architecture, and a current Pcell of the UE is a cell 1. In order to better provide service for the UE, the network side decides to add a cell2 as the Scell of the UE.

step 1, the connected UE sends RRC message containing measurement result to DU;
step 2, DU transmits the RRC message to CU;
step 3, the CU determines to add a cell2 as Scell according to the measurement result in the RRC message;
and step 4, the CU sends a UE context modification request message to add the Scell. CU sends the measurement result reported by UE to DU at the same time;
step 5, the DU determines the state of the newly added cell to be active according to the received measurement result and the saved UE context. The DU sets the state of the newly added Scell as active in a message structure corresponding to the bottom layer configuration, namely CellGroupConfigure, and is contained in a UE context modification response message;
