Claim:
1. A method of allocating uplink power in a multiple-TA (Multiple Timing Advanced) environment, from a perspective of a user equipment that applies a multiple-TA in a multiple-component carrier system including a first component carrier and a second component carrier, the method comprising: calculating PUSCH (Physical Uplink Shared Channel) transmission power of a subframe m of the first component carrier, and a subframe k and a subframe (k+1) of the second component carrier, based on required power of a PUSCH of the former half and the latter half of the subframe m, which respectively overlap, in time, the latter half of the subframe k and the former half of the subframe (k+1) of the second component carrier, PUSCH available power with respect to the component carriers, and PUSCH required power of the latter half of the subframe k and the former half of the subframe (k+1); and setting the PUSCH transmission power of the subframe m, based on the calculated power, and executing uplink transmission to a base station through the subframe m.
