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.
