  • Patent number: 7376094
    Abstract: Based on a selected criterion, a BTS (Base Transceiver Station) for each mobile station (MS) determines an antenna pattern in a reverse channel, based on combined weight factors in weighed combining of signals from antenna array elements during MS signal receiving, and in the forward channel, based on combined weight factors in weighed combining of signals from antenna array elements during MS signal transmission. The antenna pattern determined in the forward channel is performed by the reverse channel signal. The antenna pattern determined in the forward channel is based on the estimate of the angle signal area of mobiles station that is the average angle of signal arrival and its angle sector or on the estimate of average angle of signal arrival only. To determine the desired signal angular area, a decision function is proposed, where powerful interference canceling is implemented.
