Abstract:
A method and apparatus for estimating a velocity of a Mobile Station (MS) in a mobile communication system are provided, in which a Base Station (BS) receives a Channel Quality Indicator (CQI) measured by the MS, calculates a decision metric by calculating variations in the CQI for a predetermined time period, and estimates the velocity of the MS based on the decision metric, referring to a velocity table in which decision metrics are mapped to mobile velocities.
