Embodiments of the present disclosure provide a method for a transmission of uplink control information (UCI), such as hybrid automatic repeat request (HARQ) information. A base station sends first indication information to a user equipment (UE), to instruct the UE to dynamically determine the UCI according to the first indication information, and the base station allocates a physical uplink control channel (PUCCH) resource to the UE to transmit the UCI. The embodiments of the present disclosure may be used to implement a feedback of the UCI information in a carrier aggregation scenario, thereby improving performance of transmitting valid UCI information.
