Abstract: Improved ACK/NACK detection in a mobile terminal of a wireless communication system is disclosed. The ACK/NACK detection uses knowledge about the power of the acknowledgment/negative acknowledgment signal along with the probability that a DTX will occur to increase the probability that the ACK signal will be correctly detected. The probability that a DTX will occur is determined by observing the transmit power commands issued to the mobile terminal. A high number of power up commands relative to power down commands may indicate a poor quality uplink meaning that a DTX is likely to occur.
