MIMO SYSTEM AND MODE TABLE

摘要

A method for determining antenna usage in a multiple input multiple output (MIMO) wireless communication system. The method includes exchanging information between terminals concerning the number of transmit antennas and number of receive antennas. In some embodiments antenna usage is based on the number of transmit antennas, the number of receive antennas, and an indication of channel quality. In some embodiments less than all of the available antennas, particularly transmit antennas, are used at a given time, with unused transmit antennas varying over time.
