BSS AP PROTOCOL FOR COOPERATION COMMUNICATION BETWEEN ACCESS POINTS IN OVERLAPPED BASIC SERVICE SET ENVIRONMENT

摘要

A protocol for transmitting data through cooperation between access points in a nested BSS environment is disclosed. According to one side, the cooperative beamforming communication method comprises the steps of: agreeing to a cooperative beamforming transmission with a second access point having a BSS area overlapped with the first access point by a first access point; transmitting, by the first access point, a CTS to the second access point; and performing the cooperative beamforming transmission with the second access point by the first access point during the cooperative beamforming transmission period determined through the agreement after a predetermined time interval after the CTS transmission is completed. .
