ABSTRACT:
Prediction of a future state of a channel from common pilot channel signals transmitted from a transceiver (e.g., a base station) may be formed at a mobile user equipment to control future transmission patterns of the transceiver at a specified time. The matching accuracy of the future transmission patterns to the channel may be improved by adaptively calculating channel prediction terms from past and present channel estimates. Using channel prediction terms, a wireless communication system with the base station having antennas operate in a closed loop transmit diversity mode, and a channel controller application at the mobile user equipment may select best antenna transmission characteristics for active antennas of the base station.
