Abstract: A wireless IEEE 802.11 communication protocol under CSMA/CA for enhanced full duplex (FD) station (STA) operations. PPDU preambles are configured to incorporate STA identification and corresponding resource unit (RU) or multiple resource unit (MRU) information. An FD AP indicates STA identification and corresponding RU/MRU index of a transmission destination in the FD preamble of a downlink (DL) PPDU; while a FD non-AP STA indicates its own STA identification and corresponding RU/MRU index in the FD preamble of a uplink (UL) PPDU. The disclosed technology mitigates many issues in regard to fake collisions, partial RU fake collisions, and real collisions, toward improving communications and efficiency and reducing latencies.

Abstract: Method and apparatus for supporting simultaneous MultiUser (MU) Multiple-Input Multiple-Output (MIMO) operations utilizing Orthogonal Frequency Division Multiple Access (OFDMA) with Uplink OFDMA Random Access (UORA). Access Points (APs) trigger and obtain short PPDUs from the stations to learn spatial filtering patterns that are utilized in adjusting antenna phase differences to obtain minimum/maximum energy from this BSR. The APs determine favored and unfavored directions of communication, which are conveyed to non-AP UORA stations as channel estimation signals. The UORA stations base broadcasting on strengths of channel estimation signals to determine eligible UORA resource units. The UORA procedure to secondary APs allows a primary AP to trigger a UL-MU MIMO transmission with the number of spatial streams exceeding the number of antennas at the primary AP.

Abstract: Full-duplex (FD) enhancements for three scenarios with multiple APs/BSSs. (1) Multiple-AP joint transmissions on a WLAN. Toward eliminating self-interferences and other issues, certain pilot signals in the PPDU are transmitted only by the primary AP. One or more secondary APs participating in the joint transmission receive the pilots to correct their clock in the following symbols. (2) Communications are performed with extended OFDM symbols sent on a second channel which facilitate NAV decoding for stations transmitting on a first channel. (3) More than one AP can perform a joint Ack/BA to a UL PPDU. The secondary AP may utilize its full duplex capability to determine the difference of receiving status between itself and the primary AP, and forward data to the primary which it had not received.
