Protocol for cooperation communication between access points in overlapped basic service set (OBSS) environment
A method for cooperative beamforming communication, is described including negotiating, at a first access point, a cooperative transmit beamforming with a second access point having an overlapped basic service set (OBSS) area with the first access point, and transmitting, from the first access point, a clear-to-send (CTS) signal to the second access point. The method, upon detecting at the first access point a completion of transmission of the CTS signal, performs at the first access point the cooperative transmit beamforming with the second access point during a time duration of the cooperative transmit beamforming and after a predetermined time interval has elapsed.
