In future cellular networks, random users' mobility as well as time-varying multimedia traffic activity make cellular networks design a challenging task. To efficiently utilize the limited wireless spectrum, it is crucial to enable cellular systems to reactively and dynamically reconfigure cells' service area and capacity. This paper proposes an effective dynamic directional cell coverage adaptation scheme combined with a rate adaptation scheme that together are aimed maximizing radio resource utilization of Wideband Code Division Multiple Access (WCDMA) systems. This approach has the capability of reconfiguring the cell coverage area online by being aware of the system conditions. It takes into account the load on the uplink direction and the pilot power allocation on the downlink direction. Simulation results show the effectiveness of the proposed scheme in increasing WCDMA system efficiency.
