Method and apparatus for determining a data rate

摘要

A data rate determining method and apparatus in a smart-antenna mobile communication system are provided. A ratio of other-cell interference to AWGN in total noise received at an MS is estimated and a power margin is applied in proportion to highly time-variant other-cell interference. Therefore, despite a change in the other cell interference between a rate decision time and an actual data transmission time, a successful data transmission rate is increased.
