<p>Wireless communications mobile terminals demodulate incoming signals according to two different demodulation algorithms. The first algorithm (120) is the primary algorithm used by the mobile terminal to prepare the signals for higher protocol level processing (130), called the enhanced algorithm. The second algorithm (140) is a secondary algorithm used primarily to determine error rates (150) to be reported back to the base station, called the basic, or conventional, algorithm. The enhanced algorithm provides improved performance as compared to the basic algorithm. The mobile terminal reports signal quality measurements to the wireless communications system (170) based on the demodulation using the basic algorithm, rather than those based on the enhanced algorithm. In alternate embodiments, the mobile terminal does not actually demodulate according to the basic algorithm, but instead maps the results from the enhanced algorithm to what the expected results would be with the basic algorithm. In either case, the signal quality measurements reported to the wireless communications system are conceptually those of the basic algorithm, not the enhanced algorithm. As such, the wireless communications system should respond as if the mobile terminal is using the basic algorithm, thereby allowing the mobile terminal to retain its performance advantage gained by using the enhanced algorithm.</p> |
