Abstract: A user equipment includes a processor and a non-transitory computer-readable storage medium storing a program. The program includes instructions to determine a frame structure of a serving cell. Each frame based on the frame structure comprises 2k subframes having at least: (N−1) downlink subframes, (N−1) uplink subframes, and one special subframe which is a first or second special subframe. N and k are each positive integers greater than or equal to 1. The program has instructions to send and receive information in frames based on the frame structure. Each frame has N downlink subframes, N uplink subframes, and (2k−2N) special subframes, where N is less than k, or N downlink subframes, (N−1) uplink subframes, and one second special subframe, where N is equal to k, or (N−1) downlink subframes, N uplink subframes, and one first special subframe, where N is equal to k.

Abstract: The present invention provides an uplink power control method, user equipment, and a base station. The user equipment includes: a receiver, configured to receive first radio resource control protocol RRC configuration information sent by a first base station, where the first RRC configuration information includes a parameter used to calculate a power headroom PH that is of the UE and that is in a first cell controlled by the first base station; and a transmitter, configured to send second RRC configuration information to a second base station. The user equipment provided in the embodiments of the present invention is applicable to a scenario in which both RRC functions of two cells are controlled by means of RRC of one base station, and moreover, when two base stations use independent RRC, transmit power of the UE can also be effectively controlled, thereby improving uplink power control compatibility.
