The present invention relates to ACK-NACK detection in an LTE wireless communication system. To determine a threshold value for an ACK-NACK transmission, an SC-FDMA signal is received from user equipment. Then, a power estimate of soft data bits is used to establish a threshold value for determining the presence of an ACK-NACK signal. Using this threshold value, a signal from the user equipment is analyzed to determine if it contains an ACK or NACK transmission. |
