摘要：
A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.
