Patent ID: 8593935

Claim:
A method of transmitting data in a multi-cell cooperative wireless communication system, the method comprising: splitting the data to be transmitted into first data and second data, wherein the data is transmitted to a serving terminal located within a cell of a base station; obtaining feedback information from a neighbor terminal located within a neighbor cell, wherein the feedback information includes at least one preferred beamforming vector determined by the neighbor terminal; determining a first beamforming vector for the first data and a second beamforming vector for the second data, wherein the first beamforming vector and the second beamforming vector are determined based on the at least one preferred beamforming vector; and transmitting, to the serving terminal and the neighbor terminal, the first data by using the first beamforming vector and the second data by using the second beamforming vector; obtaining Signal to Interference plus Noise Ratio (SINR) information from the serving terminal; obtaining SINR information from the neighbor terminal; determining a first data transmission rate for the first data and a second data transmission rate for the second data according to the SINR information of the serving terminal and the SINR information of the neighbor terminal; and transmitting the first data according to the first beamforming vector and the first data transmission rate and transmitting the second data according to the second beamforming vector and the second data transmission rate.
