摘要：Transmitting a acknowledge/not acknowledge (ACK/NACK) response in a
wireless cellular network by mapping the data value into a cyclic shifted version of areference signal. A subframe is formed with a plurality of symbols with certain symbolsdesignated as reference signal (RS) symbols. The receiver and transmitter both knowwhen an ACK/NACK response is expected. If an ACK/NACK response is not expected, thenan RS is inserted in the duration of symbols designated as RS symbols. If an ACK/NACKresponse is expected, then the ACK/NACK response is embedded in one or more of thesymbols designated as RS symbols. The subframe is transmitted to a receiver, and thereceiver can determine the ACK/NACK value in the RS symbol, if present, and also use theRS symbol for coherent demodulation of a CQI (channel quality indicator) or data.
