COMPENSATION METHOD, BASE STATION, AND USER EQUIPMENT FOR UPLINK POWER CONTROL IN A COMP SYSTEM

摘要

The embodiments of the present invention provide a compensation method, base station, and user equipment for uplink power control in a CoMP system. The method comprises: a base station determining an adjustment value for the uplink sending power of a UE; the base station sending to the UE indication information and the adjustment value for the uplink sending power of the UE, the indication information being used for indicating the range of the adjustment value for the uplink sending power of the UE, so that the UE, according to the indication information and the adjustment value for the uplink sending power of the UE, determines the uplink sending power of the UE. The embodiments of the present invention are capable of avoiding the problem in the prior art that the uplink power control through the path loss acquired by the UE is not precise enough because in a CoMP system a data receiving point for uplink data transmission might be inconsistent with a data sending point for downlink data transmission, thereby enhancing the quality of sending uplink data.
