Abstract
A method of transmitting data in a multi-cell cooperative wireless communication system is provided. The method includes splitting data to be transmitted into first data and second data, determining a first beamforming vector for the first data and a second beamforming vector for the second data, and transmitting the first data by using the first beamforming vector and the second data by using the second beamforming vector. The present invention provides a data transmission method which does not cause deterioration of overall system performance while minimizing inter-cell interference.
Claims20
A method of transmitting data in a multi-cell cooperative wireless communication system, the method comprising:
- splitting data to be transmitted into first data and second data;
- determining a first beamforming vector for the first data and a second beamforming vector for the second data;
- and
- transmitting the first data by using the first beamforming vector and the second data by using the second beamforming vector.
A method of transmitting feedback information in a multi-cell cooperative wireless communication system, the method comprising:
- estimating a first channel state with respect to a serving base station and a second channel state with respect to a neighbor base station;
- determining feedback information comprising beamforming information for data transmission of the neighbor base station by considering the estimated first and second channel state;
- and
- transmitting the feedback information to the neighbor base station.
