Abstract
Transmitting an ACK/NACK 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 ACK/NACK response is expected. If an ACK/NACK response is not expected (706) then an RS is inserted (708) in the duration of symbols designated as RS symbols. If an ACK/NACK response is expected then the ACK/NACK response is embedded (710) 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 ACK/NACK value in the RS symbol if present and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.
