Abstract

A method of controlling uplink power in a multi-cell environment including a plurality of base stations includes receiving a power control message from a base station, wherein the power control message comprises an noise and interference (NI) level of at least one permutation zone of a neighbor base station, and controlling transmission power based on the power control message. The UE can be more accurately control its transmission power, so that the inter-cell interference can be reduced, the NI level can be lowered, and power consumption of the UE can be reduced.
