Abstract
Provided is an access point grouping method to be performed in a high speed mobile environment and a communication system using the access point grouping method. A system capacity may be improved by grouping users having different movement speeds with respect to various channel environments classified based on existence of an LOS channel, and by performing beamforming. Channel information with respect to a user moving at a high speed may not be required, and thus overhead may be reduced.
