Abstract:
Embodiments of the present invention disclose a power control method, a user equipment, and a base station. The method according to an embodiment of the present invention includes the following: a user equipment UE receives a transmitter power control TPC command sent by a base station, where the TPC command is used to indicate a power adjustment value of one carrier; and if the UE does not send a physical uplink control channel PUCCH in a previous uplink subframe of a current uplink subframe of the one carrier, performing, by the UE, according to a PUCCH transmit power used when the UE sends a latest PUCCH from among multiple carriers and the power adjustment value, TPC accumulation to obtain an updated PUCCH transmit power of the one carrier, where the multiple carriers include the one carrier.
