SYSTEM AND METHOD FOR RESELECTING ANTENNAS IN A CELLULAR MOBILE COMMUNICATION SYSTEM USING MULTIPLE ANTENNAS
First Claim
1. A method for reselecting an antenna for a mobile station by a home base station forming a data channel to the mobile station having at least two antennas in a cellular mobile communication system using multiple antennas, the method comprising the steps of:
- receiving from the mobile station channel qualities of first antennas of the home base station and second antennas of a neighbor base station of the home base station;
determining whether to reselect antennas for the mobile station according to the channel qualities; and
selecting at least two antennas from among the first antennas and the second antennas;
wherein the at least two antennas are selected based on the measured channel qualities.

Abstract
A cellular mobile communication system using multiple antennas reselects a plurality of transmission antennas of base stations connected to a mobile station. The system includes measuring a channel quality parameter used for estimation of channel performance, determining whether to reselect the transmission antennas using the measured channel quality parameter, reselecting transmission antennas of the base stations connected to the mobile station, and connecting the reselected transmission antennas to the base station.
