Abstract:
A method for closed loop transmit diversity that includes receiving data from user equipment (UE) that was transmitted using multiple transmit antennas, selecting a new transmit antenna for the UE, determining a new cycle period for the UE, and sending a new transmit antenna index and a testing indication based on the new cycle period to the UE.
