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 data channel by a mobile station in a cellular mobile communication system that includes the mobile station having at least two antennas, a home base station having a plurality of antennas, at least one of which is used to form the data channel to the mobile station, and at least one neighbor base station of the home base station, the method comprising the steps of:
- determining whether to reselect antennas based on channel qualities of first antennas of the home base station and second antennas of the neighbor base station; and
selecting at least two antennas from among the first antennas and the second antennas based on the channel qualities;
wherein the mobile station transmits the measured channel qualities to the home base station, and performs the antenna selecting step in response to a command from the home base station.

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.
