Claim Text:
1. A power control method, comprising: receiving, by a user equipment (UE), a transmitter power control (TPC) command sent by a base station, wherein the TPC command is used to indicate a power adjustment value of one carrier; 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, wherein the multiple carriers comprise the one carrier; adjusting a transmit power of the one carrier according to the power adjustment value; for each carrier, calculating, by UE, a time difference between a current moment and a moment when the latest PUCCH is sent on the each carrier; querying, by the UE, a carrier with the smallest time difference; acquiring, by the UE, a PUCCH transmit power used when a latest PUCCH is sent on the found carrier; and obtaining, by the UE, according to the TPC command, the power adjustment value in the found power adjustment value set.
