Title: Method and apparatus for reliable transmit power and timing control in wireless communication
Inventor: SANKAR HARI
IPC: H04B7/26
Filed: 2006-08-25
Abstract: Techniques for improving reliability of control information are described. A transmitter determines if improved reliability is applicable for at least one control symbol to be sent in a timeslot. The transmitter sends the control symbol(s) without improved reliability if deemed not applicable and with improved reliability if deemed applicable. A receiver receives the control symbol(s) and identifies each received control symbol as a reliable control symbol or an unreliable control symbol based on the received signal quality of the received control symbol and a threshold. The receiver adjusts a control loop based on reliable control symbols. The receiver also combines unreliable control symbols to obtain combined symbols and selectively adjusts the control loop based on the combined symbols. The control loop may be for transmit power or timing.
