Patent ID: 8286052

Claim:
A method of detecting an enhanced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator, the method comprising: a wireless transmit/receive unit (WTRU) receiving an E-DCH H-ARQ indicator channel (E-HICH) transmission carrying an H-ARQ indicator; the WTRU calculating a log likelihood ratio (LLR) of a conditional probability that an acknowledgement (ACK) indicator is transmitted to a conditional probability that a non-acknowledgement (NACK) indicator is transmitted; the WTRU comparing the LLR to a predetermined threshold; and the WTRU determining the H-ARQ indicator as a NACK indicator on a condition that the LLR is below the threshold, and determining the HARQ indicator is an ACK indicator on a condition that the LLR is not below the threshold.
