Abstract: A method for transmission of media access control (MAC) protocol data units (MPDUs) over a wireless local area network (WLAN) communication channel is described. A first physical layer (PHY) data unit is generated at a first communication device. The first PHY data unit has i) a data field that includes a first MPDU to be transmitted to a second communication device, and ii) a PHY signal field that includes a transmission version field set to indicate an initial transmission of the first MPDU. The first PHY data unit is transmitted over the WLAN communication channel to the second communication device. It is determined, at the first communication device, whether a first acknowledgment to the first MPDU has been received from the second communication device. In response to determining that the first acknowledgment has not been received, a second PHY data unit is generated at the first communication device. The second PHY data unit has i) a data field that includes the first MPDU, and ii) a PHY signal field that includes a transmission version field set to indicate a retransmission of the first MPDU. The second PHY data unit is transmitted over the WLAN communication channel to the second communication device.

Abstract: Methods and apparatus are provided for directing a beam towards a receiving device in the presence of interference. A beam transmitted by a transmission source is received by a received device. The beam shape is affected by signals transmitted by interfering sources. The receiving device computes channel estimates associated with the transmission source and the interfering sources. A feedback signal that represents the channel estimates associated with the transmission and interfering sources is transmitted to the transmission source. The transmission source changes characteristics of the beam to compensate for the interference caused by the interfering sources. The transmission source may change the characteristics of the beam by performing precoding algorithms.
