Abstract
The present specification relates to a method and device for allocating uplink power in multiple-TA environments. The method comprises: calculating transmission powers of a PUSCH for subframe m of a first component carrier and subframes k and (k+1) of a second component carrier by using required powers of the PUSCH for the first half and second half of subframe m, which temporally overlaps with the second half of subframe k and the first half of subframe (k+1), available powers of the PUSCH for the first and second components carriers, and required powers of the PUSCH for the second half of subframe K and the first half of subframe (k+1) in a user equipment to which multiple TAs are applied; and setting the transmission power of the PUSCH for subframe m according to the calculated transmission powers and performing uplink transmission to a base station through the subframe m.
