Abstract
A method and apparatus for transmitting/receiving pilot symbols for demodulation of control channel information in the uplink of a wireless communication system are provided. When an Evolved Node B (ENB) expects to receive both the Channel Quality Information (CQI) and the Acknowledgement (ACK)/Negative ACK (NACK) from a User Equipment (UE) in a certain subframe if the UE transmits only the CQI channel the ENB is prevented to detect the nonexistent ACK/NACK information from the CQI channel thereby avoiding false alarm.
