Abstract

A method and apparatus for wireless communications wherein a base station (102) transmits a signal to sending data to a subscriber station (108) through a signal beam (110) that sweeps through the coverage area of the base station (102). User data addressed to the subscriber station (108) is buffered until the signal beam angle of the signal (110) beam allows efficient transmission. The base station (102) may alter the beam sweep speed or the shape of the beam's radiation pattern (106) over time to maximize system efficiency and capacity.
