Abstract
The performance of closed loop transmit diversity (CLTD) systems may be improved, in accordance with aspects of the present invention, by encoding antenna control information fed back from a mobile station to a base station. As compared to prior art CLTD systems that send antenna control bits in unencoded feedback messages, encoding the antenna control information may result in reduced feedback delays and reduced transmission power. Further, in accordance with some aspects of the present invention, the antenna control bits may be fed back to the base station on a common feedback channel also used to feed back channel quality indication, thus reducing processing overhead.
