This paper presents an adaptive admission control (AC) strategy for WCDMA multicellular networks which employ antenna arrays (AAs) at the base station (BS). The adaptive AC strategy generates beams that focus the transmitted power in the directions of desired users, thus minimizing interference and increasing capacity. A WCDMA system level simulator has been developed in order to evaluate the performance of the proposed adaptive AC strategy by means of Monte Carlo(MC) simulations. Results for different traffic scenarios with up to four tiers of interfering cells show that a network with the adaptive AC strategy can achieve almost two times higher throughput per beam when compared to the traditional AC in a multirate multicellular environment with hotspot areas.
