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

摘要

Embodiments of the present invention provide a compensation method, a base station, and a user equipment for uplink power control in a CoMP system. The method includes: a base station determines an adjustment value for an uplink sending power of a UE; the base station sends to the UE indication information and the adjustment value for the uplink sending power of the UE, where the indication information is used for indicating a 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. Embodiments of the present invention are capable of avoiding the problem in the prior art that the uplink power control according to a 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 improving the quality of sending uplink data.
