    Abstract: Disclosed is a protocol for transmitting data through cooperation between access points in an overlapped basic service set (OBSS) environment. A cooperative beamforming communication method may include negotiating, by a first access point, a cooperative transmit beamforming with a second access point having an OBSS area with the first access point; transmitting, by the first access point, a clear-to-send (CTS) to the second access point; and performing, by the first access point, the cooperative transmit beamforming with the second access point during a cooperative transmit beamforming duration determined through the negotiation after a predetermined time interval is elapsed, when transmission of the CTS is completed.
