Abstract
A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.
