Abstract
In the communications system of the present invention, a communications terminal determines a precoding matrix index in a pilot signal received through a specific downlink channel, examines channel quality information of the downlink channel according to the determined precoding matrix index, and transmits feedback information to a serving base station, which determines a priority factor by using the examined channel quality information, and compares the priority factor with other priority factors. The comparison is used such that a base station having a high priority suggests the use of the precoding matrix to the neighboring base station.
