POWER CONTROL METHOD AND APPARATUS

摘要

A power control method is disclosed in the present invention, which is applied to the field of communications. The method includes: the power headroom information of aggregated carriers of a user equipment is obtained, wherein the aggregated carriers include at least one component carrier group and at least one first carrier, or include at least one component carrier group, or include at least two first carriers, wherein the component carrier group includes at least two second carriers, and wherein the first carrier and the second carrier are single carriers (101); the transmission power of the aggregated carriers is adjusted according to the power headroom information (102). With the present invention, the power headroom of the aggregated carriers of the user equipment can be reported in a multi-carrier scenario, a base station can reliably control the transmission power of the user equipment, and thereby the reliability and the throughput of a system are improved.
