Abstract: A Spatial Multiple Access Uplink for Wireless LANs is generally described herein. A novel FD-MiMAC, protocol leverages full duplex functionality at the Access Point, can be incrementally deployed with current 802.11 Access Point and client devices, can be easily implemented by client devices in a distributed and contention based manner, and pairs users in uplink MU-MIMO to enhance system performance. A method for spatial multiple access uplink in a wireless local area network comprises announcing, by an Access Point (AP), its available remaining antenna capability, receiving, by the AP, a packet header frame transmitted by a winning client uplink contender, allocating, by the AP, uplink resources for the winning client uplink contender and immediately announcing its remaining antenna capability, and transmitting, by the AP, at the end of a winning client's transmission burst, an Acknowledge-to-All frame, whereby other clients may simultaneously restart contention for transmission of next frames.
