1. A method, applied to a communication device, the method comprising:
receiving a configuration message from a base station, wherein the configuration message is usable for determining that a channel status information (CSI) report of a first secondary cell is sent by using a physical uplink control channel (PUCCH) of a second secondary cell, and wherein the configuration message comprises at least one information element, and each information element of the at least one information element indicates an identity of a secondary cell corresponding to identity information of the second secondary cell;
determining, according to the configuration message, identity information of the first secondary cell that uses the PUCCH of the second secondary cell to transmit the CSI report;
receiving a secondary cell activation command instructing activation of the first secondary cell, wherein the secondary cell activation command is usable for instructing activation of at least one secondary cell and comprises a cell identity corresponding to the first secondary cell; and
sending, at a preset time after the secondary cell activation command is received, a first CSI report of the first secondary cell over the PUCCH of the second secondary cell, wherein the second secondary cell is in active state.
