    摘要: A base station and method are described herein that improves the coverage in a fixed-beam wireless communication system by using antenna beam-jitter and Channel Quality Information (CQI) correction. In one embodiment, the method includes the steps of: (a) modifying a beam by introducing a beam-jitter in a beam-forming pattern; (b) receiving an estimated channel quality information, CQI, from a user terminal; (c) accounting for effects of the beam-jitter on the estimated CQI to obtain a jitter-adjusted CQI estimate; (d) and using the jitter-adjusted CQI estimate during user scheduling for a future transmission to the user terminal.
