Abstract:
Embodiments provide a method for controlling an uplink transmit power in inter-base station carrier aggregation. 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, 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.
