Abstract
Methods and apparatus for identifying a subscriber station which is in motion, determining a mobility metric indicative of a level of mobility of the subscriber station and varying or updating one or more operating parameters based on the mobility metric. An apparatus can determine a measure of mobility based on one or a combination of a plurality of factors, such as variations in signal strength, variations in a channel estimate, or variations in phase or frequency of a particular signal or signal component. The one or more measures of mobility can be combined to form a single measure of mobility, the measure of mobility can be quantized to a predetermined number of mobility levels and one or more operating parameters can be varied or adjusted based on the mobility level.
