Abstract
Transmitting an ACWNACK response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed (704) with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACWNACK response is expected. If an ACWNACK response is not expected (706) then an RS is inserted (708) in the duration of symbols designated as RS symbols. If an ACWNACK response is expected then the ACWNACK response is embedded (7 10) in one or more of the symbols designated as RS symbols. The subframe is transmitted (712) to a receiver and the receiver can determine the ACWNACK value in the RS symbol if present and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.
