Abstract
A method of communicating data to M receiving antennas from N transmitting antennas, where M and N are integers and unequal, has the steps of sending a message to determine a number of transmit paths to be used, awaiting an acknowledgement message comprising a number of receiver paths, setting the number of transmit paths based on at least the acknowledgement message, producing data streams from outbound data based on the number of transmit paths, applying the data streams to a space/time encoder to produce encoded signals and transmitting the encoded signals from at least a portion of N transmitting antennas.
