Method for grouping access points in high speed mobile environment and communication system using the method

摘要

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.

1. A communication method of a base station, the method comprising:
grouping at least two access points to include an access point moving at a first range speed and at least one access point moving at a second range speed, the grouping being performed based on movement speed information associated with the at least two access points and information associated with whether line of sight (LOS) channels exist between the at least two access points and a base station, and the first access range speed being faster than the second access range speed; and generating a transmission beamforming vector based on a result of the grouping based on the movement speed information and the information associated with whether the LOS channels exist.
