Abstract:
A method that is implemented by a base station to decode a high speed dedicated physical control channel (HS-DPCCH) using a preamble and postamble of a hybrid automatic repeat request (HARQ) message while maintaining a fixed false alarm probability of interpreting a discontinuous transmission (DTX) as a HARQ acknowledgement (ACK) or HARQ negative acknowledgement (NACK). The method includes a set of steps, including receiving a signal from a user equipment (UE). The signal is despread using a G-RAKE demodulator. The despread signal is combined to produce a combined symbol estimate vector x including a preamble and postamble of the HARQ message. The combined symbol estimate vector x is checked to determine whether the signal includes a DTX, HARQ ACK or HARQ NACK, and then the DTX, HARQ ACK or HARQ NACK is output.
