Abstract

The invention discloses a method and apparatus for diagnosing a backhaul communications link between a repeater station and a base transceiver station of a wireless communication system. Adjacent and co-channel interference can severely degrade the performance of the backhaul communication link. As a result, the conditions on the backhaul link channels can be continually monitored to ensure optimal performance of the link. Each RF channel on the backhaul communication link is individually diagnosed. A signal is then sent over the RF channel and the signal strength is measured along with any adjacent and co-channel interference. The measured statistics are then sent back to the base transceiver station. In a further embodiment of the invention, the power level of a RF carrier signal on the backhaul communication link is measured and the carrier signal is then turned off. The power levels on the adjacent channels--above and below are then measured. Based on these measurements and other channel statistics, the power level of the RF carrier signal is accordingly adjusted.
