Abstract

A method and apparatus for selecting a beam combination of multiple-input multiple-output (MIMO) antennas are disclosed. A wireless transmit/receive unit (WTRUs) includes a plurality of antennas to generate a plurality of beams for supporting MIMO. At least one antenna is configured to generate multiple beams, such that various beam combinations can be produced and a desired beam combination selected for conducting wireless communication with another WTRU. A quality metric is measured with respect to each or subset of the possible beam combinations. A desired beam combination for MIMO transmission and reception is selected based on the quality metric measurements.
