Abstract: The present invention discloses a method for reporting a power headroom report and a user equipment, which are applied in the field of communications. The method includes triggering reporting of a first power headroom report and determining that a condition of sending the first power headroom report is satisfied. The condition of sending the first power headroom report includes a determination that uplink data channel transmission occurs in a current transmission time interval. The first power headroom report is obtained. The first power headroom report includes a first power headroom value that includes a difference between maximum transmitting power of a carrier and a sum of transmitting power of a control channel of the carrier and transmitting power of a data channel of the carrier.

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.
