A UE with carrier aggregation capability can transmit and receive data on multiple CCs at the same time. The CC that the UE initially accesses is a Primary Component Carrier (PCC). The base station can also change the PCC of the UE through configuration. The other CCs are called Secondary Component Carriers (SCCs), and the SCCs are connected to the UEs. After the state is configured by the base station. The serving cell (Serving Cell) corresponding to the PCC is called a primary cell (PCell), and the serving cell corresponding to the SCC is called a secondary cell (SCell). The base station allocates only one Cell Radio Network Temporary Identifier (C-RNTI) for each UE, that is, the C-RNTI of each serving cell allocated by the UE is the same. Each serving cell allocated to the user equipment (UE) has a configured identifier, called a serving cell identifier, and the serving cell identifier of the PCell is fixed to 0, and the serving cell identifiers of the SCell are numbered sequentially from 1.
