Method and device for allocating uplink power in multiple TA environments

摘要

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.

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.
