    Abstract: This disclosure relates to methods for transmitting and receiving multi-user request-to-send and clear-to-send frames in a wireless communication system. An access point wireless device may establish wireless connections with multiple wireless devices. The access point wireless device may transmit a multi-user request-to-send frame to the wireless devices. The multi-user request-to-send frame may indicate a transmit opportunity duration and allocate frequency resource units on which to transmit clear-to-send frames to the wireless devices. The wireless devices may transmit the clear-to-send frames on the allocated frequency resource units. The clear-to-send frames can include an indication of partial or full availability for the transmit opportunity.

    Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a trigger frame addressed to a second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard (such as IEEE 802.11ax or a subsequent IEEE 802.11 standard). Then, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard. When the second electronic device indicates support for the modified response frame during association with the electronic device, the interface circuit may define parameters associated with the modified response frame in an association response.

    Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a management frame addressed to a second electronic device. Then, the interface circuit may provide a trigger frame addressed to the second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard. Next, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard, and modifications to the modified response frame are specified in the management frame.

    Abstract: Systems, methods, and mechanisms for preemption of non-low latency data within an aggregated medium access control (MAC) protocol data unit (AMPDU), e.g., such as in current and future IEEE 802.11 systems. A wireless device (e.g., an access point or wireless station) may transmit, during an AMPDU, a trigger to receive (TRX) frame. The TRX frame may indicate preemption of non-low latency data intended for a first wireless station with low latency data intended for a second wireless station, e.g., via an acknowledgement policy change. Additionally, the wireless device may be configured to transmit, to the second wireless station, the low latency data within the AMPDU. Further, the wireless device may be configured to receive, after the AMPDU transmission is complete, a multi-block acknowledgement (M-BA) frame from the second wireless station. The M-BA frame and completion of the AMPDU transmission are separated by a short inter-frame space (SIFS).
