Rate control and distributed reverse link scheduling in CDMA systems are considered. Probabilistic rate allocation with and without token bucket constraints gives mobiles more autonomy in making transmission decisions. A system with adaptive antenna arrays deployed at the base stations is proposed as a generalization to the model with omnidirectional antennas. Uniform linear antenna arrays with a microstrip patch as their constituent element are presented. Their number of elements is varied and their performance is compared to the omnidirectional case, showing substantial throughput gains.
