| 发明名称 | Protocol for cooperation communication between access points in overlapped basic service set (OBSS) environment | ||
| 摘要 | 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. | ||

A method for cooperative beamforming communication, the method comprising: 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; transmitting, from the first access point, a clear-to-send (CTS) signal to the second access point; and upon detecting at the first access point, a completion of transmission of the CTS signal, performing 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. | ||
