METHOD FOR CONTROLLING UPLINK TRANSMISSION POWER OF INTER-BASE STATION CARRIER AGGREGATION, BASE STATION AND DEVICE

摘要

Embodiments of the present invention provide a method for controlling an uplink transmit power in inter-base station carrier aggregation, a base station, and a device. The method includes: acquiring, by a first base station, a maximum uplink transmit power that is allocated by user equipment UE to the first base station, and configuring, by the first base station, an uplink transmit power for the UE according to the maximum uplink transmit power. In the method provided by the present invention, because the maximum transmit power allocated to the first base station is allocated according to status information of an uplink resource of a second base station, a power that is allocated by the UE to each base station can be coordinated. Therefore, the first base station can accurately allocate an uplink transmit power to the UE, and a throughput of the UE is increased while requirements of multiple base stations for transmit powers are satisfied. Because statuses of uplink resources configured by other base stations are considered between base stations, a phenomenon of waste of the allocated uplink transmit power may be reduced, and even avoided, thereby improving transmission efficiency.
