Cooperative beamforming apparatus and method in wireless communication system

摘要

A cooperative beamforming apparatus and method in a wireless communication system supporting channel sensitive scheduling based on feedback information is provided. A beamforming method in a wireless communication system according to the present invention includes transmitting, at a mobile station, a channel condition information of a channel of a serving base station to the serving base station and a channel condition information of a channel of a neighbor base station; and forming, at the serving base station, a beam based on the channel condition information to transmit a signal and, at the neighbor base station, a beam to transmit a signal.

主权项

1. A beamforming method of a mobile station in a wireless communication system, comprising:
transmitting a channel condition information of a channel of a serving base station to the serving base station; transmitting a feedback information regarding suppressing interference of a channel of a non-serving base station to the non-serving base station; and receiving from the serving base station, a control information about a beam formed based on the channel condition information to transmit a signal, wherein the channel condition information of the serving base station comprises a Channel Quality Indicator (CQI) and a Precoding Matrix Indicator (PMI), and wherein the feedback information of the non-serving base station comprises a PMI.
