Abstract
An uplink transmission power control method and a user equipment are provided, where the method includes: determining, by a UE, whether uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers; where the adjacent subframes between the multiple carriers are partially overlapped; and timing advance values of the multiple carriers are different; and if uplink channels are simultaneously transmitted over adjacent subframes between multiple carriers, processing, by the user equipment, an uplink channel transmitted over the last symbol on a partially overlapped subframe of another carrier except a carrier having the greatest timing advance value, so that total transmission power of the uplink channels is lower than the maximum transmission power or an interference level of the user equipment.
