Abstract
A power control method is provided, which is applicable to the communication field. The method includes: obtaining power headroom information of an aggregated carrier of a User Equipment (UE), where 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; and adjusting transmit power of the aggregated carrier according to the power headroom information. The method enables reporting of power headroom of an aggregated carrier of the UE in a multi-carrier scenario, so that the base station can control the transmitting power of the UE reliably, and therefore, reliability and throughput of the system are improved.
