Abstract: Provided is a method for determining a Hybrid Automatic Repeat Request (HARQ) transmission signal. The method comprises receiving soft bits from a wireless communication physical channel uplink signal, said received soft bits being deemed to comprise HARQ LLRs and soft decoding said HARQ LLRs to output a hard ACK/NACK decision. The method includes processing said HARQ LLRs based on said hard ACK/NACK decision such that the processed HARQ LLRs map to a same or identical constellation point or points if the physical channel uplink signal contains an ACK or NACK transmission signal. The method also includes using said processed HARQ LLRs to determine if the physical channel uplink signal contains an ACK or NACK transmission signal or to determine if the physical channel uplink signal comprises discontinuous transmission (DTX).
