Abstract: Embodiments of an access point (AP) configured for extremely high throughput (EHT) operation may be configured to operate as a triggering AP for a trigger-based (TB) peer-to-peer (P2P) communication between a triggered direct (TD) station (STA) and a TD peer STA. The AP may encode a Direct Link Announcement (DiL-A) frame to schedule the TD STA for a direct link transmission to the TD peer STA. The DiL-A frame may be encoded to include a Duration/ID field. The AP may set the Duration/ID field of the DiL-A frame to a remaining duration of a transmission opportunity (TXOP) when the TD peer STA is an EHT STA that supports TB P2P operation (e.g., to allow the TD peer STA to ignore the NAV set by the DiL-A frame). The AP may set the Duration/ID field of the DiL-A frame to a response time for the TD STA to respond to the DiL-A frame when the TD Peer STA is a legacy STA (e.g., to allow the TD peer STA to set its NAV based on the response time).

Abstract: To communicate with a plurality of non-AP stations (STAs) within synchronized transmission opportunities (S-TXOPs), an access point station (AP) performs an initial management frame exchange with the STAs. During the initial management frame exchange, one or more sets of semi-static allocation parameters are signalling to the STAs. Each set of semi-static allocation parameters is associated with an allocation index (IDx). The AP may communicate data with the STAs during S-TXOPs that follow the initial management frame exchange. Each of the S-TXOPs may include an S-TXOP trigger. The S-TXOP trigger may be encoded to include one of the allocation indices to indicate a known allocation for use during the associated S-TXOP when a set of the predetermined semi-static allocation parameters are to be used. The S-TXOP trigger may be encoded to include full allocation information to indicate a new allocation for use during the associated S-TXOP when the predetermined semi-static allocation parameters are not used.

Abstract: An access point (AP) station (STA) configured for communicating with another STA within a synchronized transmission opportunity (S-TXOP) may encode an S-TXOP trigger for transmission at a beginning of the S-TXOP.
