METHOD FOR IMPROVING CELL PERFORMANCE USING THE FEEDBACK OF PRECODER RECOMMENDATION INFORMATION IN MULTI-CELL WIRELESS NETWORK

摘要

The present invention relates to a method of improving cell performance using feedback of precoder recommendation information in a multi-cell wireless network, and in which downlink communication is performed using a predetermined beam pattern by inter-cell cooperation in a multi-cell wireless network, It is recommended to use an unused precoder, which is likely to provide higher reception performance than the precoder in use, to improve the cell performance of the cell boundary terminal by minimizing feedback information by changing the beam pattern of the current base station do. According to an aspect of the present invention, there is provided a method of improving cell performance in a base station of a multi-cell-based wireless network, the method comprising: transmitting data to a service target terminal according to an initial beam pattern allocated by inter- Receiving precoder recommendation information from a terminal that is not a service target; And modifying the initial beam pattern and the service target terminal based on the precoder recommendation information if the base station is selected as a beam pattern change target through collaboration with the adjacent cell.
