CELL ACTIVATION METHOD AND COMMUNICATION APPARATUS

Provided in the present application are a cell activation method and a communication apparatus, which can be applied to scenarios such as carrier aggregation and are particularly suitable for the activation of high-frequency secondary cells. The method comprises: by means of a first cell, receiving first configuration information from a network device, the first configuration information indicating N time-frequency resources in one-to-one correspondence with N temporary reference signals (TRSs); on K time-frequency resources among the N time-frequency resources, receiving K TRSs among the N TRSs; and further activating a second cell according to the K TRSs. Compared with implementing cell activation by means of physical broadcast channel blocks (SSBs), the present application configures dedicated TRSs for terminal devices, thus lowering the time delay of activating secondary cells. Sont proposés dans la présente demande un procédé d'activation de cellule et un appareil de communication, qui peuvent être appli
