    Abstract: A wireless local area network (WLAN) protocol allowing a Transmit Opportunity (TXOP) holder to share the TXOP with other stations. An intent to share the TXOP is communicated to the Access Point (AP). Upon gaining channel access, the TXOP holder directly or indirectly communicates that the TXOP can be shared with other STAs, after which scheduling information (time and duration) are shared with the STAs. When the TXOP occurs, the STAs can access the channel at the time and for the duration specified, thus providing increased use of the TXOP to improve efficiency.

    Abstract: A wireless protocol allowing an AP to allocate time within a transmit opportunity (TXOP) to non-AP stations. The allocations are made under condition that the non-AP STA(s) will satisfy Access Class (AC) requirements communicated in a frame sent by the AP STA, such as within an MU RTS TXS Trigger frame. Upon receiving the frame, the non-AP responds on whether it can meet the conditions, such as within a Clear-To-Send (CTS) message. If the non-AP can meet the conditions, then it proceeds to transmit data (to the AP, or a peer non-AP). Otherwise, if it cannot meet the conditions, then the AP can communicate the allocation to another non-AP STA. There are also conditions for how the non-AP can aggregate data units into A-MSDUs.

    Abstract: Enhanced Multi-Link Operation (MLO) is performed in this protocol in which non-simultaneous transmit/receive (NSTR) Multi-Link Devices (MLDs) cooperate with each other in sharing a portion of their available Transmit Opportunity (TXOP) toward reducing contention and competition for channel access across the group of cooperating MLDs. The shared TXOP is performed at an MLD level after all links for an NSTR MLD are obtained by stations which do not need to be in part of the same NSTR MLD, thus synchronized transmissions and receptions are performed which eliminate in-device coexistence (IDC) interference in any single NSTR MLD. The time gap while awaiting for all links to be obtained, is also made use of for performing transmission(s) toward increasing data throughput.
