Method and Apparatus for Power Control

摘要

A power control method includes obtaining power headroom information of an aggregated carrier of a User Equipment (UE). The aggregated carrier includes at least one component carrier group and at least one first carrier, or includes at least one component carrier group, or includes at least two first carriers. The component carrier group includes at least two second carriers, and the first carrier and the second carrier are single carriers, The method also includes adjusting transmit power of the aggregated carrier according to the power headroom information.

主权项

1. A non-transitory computer readable medium in a base station communicating with a user equipment (UE), wherein an aggregated carrier of the UE comprises a plurality of first carriers and each of the first carriers is a single carrier, and wherein the medium stores a program causing a computer to execute a process comprising:
receiving power headroom information of each of the first carriers of the UE on one first carrier among the plurality of first carriers; and determining adjustment of transmitting power of the aggregated carrier according to the power headroom information; wherein the power headroom information of each of the first carriers comprises a difference between the maximum transmitting power of each of the first carriers and an estimated transmitting power of the corresponding first carrier of the plurality of first carriers; wherein the difference between the maximum transmitting power of each of the first carriers and an estimated transmitting power of the corresponding first carrier of the first carriers comprises:
the difference between the maximum transmitting power of one first carrier of the first carriers and a sum of transmitting power of a control channel of the same first carrier and transmitting power of a data channel of the same first carrier, and the difference between the maximum transmitting power of the same first carrier and transmitting power of the data channel of the same first carrier; andthe difference between the maximum transmitting power of another one the first carriers and transmitting power of a data channel of the corresponding carrier.
