Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.

Abstract: This disclosure provides methods, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device and a second wireless device (e.g., access points, stations) may support transmission opportunity (TXOP) sharing procedures. The second wireless device may transmit a frame indicating a capability of the second wireless device to support one or more triggered TXOP sharing modes. The second wireless device may transmit an indication (e.g., a frame) indicating to change support for the triggered TXOP sharing modes based on the capability. The change may indicate to suspend, resume, disable, or enable the triggered TXOP sharing modes. For example, the second wireless device may transmit an indication to suspend support of a first triggered TXOP sharing mode that enables the second wireless device to perform peer-to-peer transmissions. Accordingly, the first wireless device may trigger the second wireless device to communicate according to the supported triggered TXOP sharing modes.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a hybrid automatic repeat request (HARQ) protocol in a wireless local area network (WLAN). In some aspects, a first WLAN device may transmit a first HARQ frame to a second WLAN device. The first WLAN device may determine whether a first feedback message received from the second WLAN device includes HARQ acknowledgement information or non-HARQ acknowledgment information. The first feedback message may be a HARQ Block Acknowledgement (H-BA) message having a multi-station Block ACK (M-BA) frame format that includes HARQ acknowledgment information. The first WLAN device may transmit a second HARQ frame to the second WLAN device in response to determining the first feedback message includes the HARQ acknowledgment information. The first WLAN device may transmit a non-HARQ frame in response to determining the first feedback message includes non-HARQ acknowledgement information.

Abstract: This disclosure provides methods, devices and systems for soliciting trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). Some implementations more specifically relate to trigger frame designs that support non-legacy TB PPDU formats. In some aspects, a trigger frame may carry information to be included in a physical layer (PHY) preamble of a TB PPDU solicited by the trigger frame. For example, the information may indicate values of one or more subfields of a universal signal field (U-SIG) associated with the non-legacy TB PPDU format. In some aspects, the information may be carried in a special user information field of the trigger frame. For example, the special user information field may be identified by a special association identifier (AID) value. The special AID value may be different than any AID values assigned to wireless communication devices in a basic service set (BSS) associated with the TB PPDU.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for preventing or reducing cross-network interference associated with a coordinated transmission on a wireless channel. A first access point (AP) of a first basic service set (BSS) and a second AP of a second BSS can concurrently use the wireless channel using a coordinated transmission during a portion of a transmission opportunity (TXOP). The TXOP owner (such as the first AP) may allocate a resource assignment to the second AP such that the resource assignment is conditionally available for use by the second AP in a coordinated transmission. The condition may prevent the resource assignment from being used by the second BSS when its use would cause interference to the first BSS. The condition may be based on a transmit power for downlink communication or uplink communication in the second BSS.
