METHODS AND APPARATUS FOR IDENTIFYING SUBSCRIBER STATION MOBILITY

摘要

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.

1. A method for operating a mobile device, the method comprising:
receiving, at the mobile device, a plurality of Orthogonal Frequency Division Multiplex (OFDM) symbols over a plurality of OFDM subcarriers from at least one base station; determining, by the mobile device, a mobility factor based at least in part on the receiving of the plurality of OFDM symbols; and modifying, by the mobile device, one or more channel operating parameters of the mobile device based at least in part on the mobility factor.
