Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

Abstract: This disclosure provides methods, devices and systems for enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information.

Abstract: This disclosure provides methods, devices and systems for generating enhanced sounding packets. Some implementations more specifically relate to sounding packet designs that support enhancements to wireless communication protocols associated with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced null data packet announcement (NDPA) frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, the enhanced NDPA frame may be configured in accordance with a legacy or a non-legacy NDPA frame format. In some other implementations, the enhanced NDPA frame may include a subfield carrying information identifying a particular basic service set (BSS) which may be associated with one or more STA information fields. Still further, in some implementations, an Extremely High Throughput (EHT) PPDU may include signaling to indicate whether the EHT PPDU is formatted as a sounding NDP.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QOS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: This disclosure provides methods, components, devices and systems for signaling mechanisms for multi-hop channel sounding for relay operation. Some aspects more specifically relate to frame addressing and transmission opportunity (TXOP) or service period (SP) sharing to facilitate a multi-hop channel sounding within a single TXOP or SP. An originating device may transmit a first frame indicating identifying information corresponding to multiple other wireless communication devices to initiate a multi-hop channel sounding involving the multiple other wireless communication devices. For example, the originating device may include, in the first frame, identifying information corresponding to a satellite access point (AP) and identifying information corresponding to an end device with which the originating device may communicate via the satellite AP. In accordance with the multi-hop channel sounding, the originating device may receive, collectively via one or more frames, channel information associated with each hop between the originating device and the end device.

Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may transmit, to a second AP and during a first portion of a transmission opportunity (TxOP), a request to participate in a multi-user (MU) transmission. The AP may receive, from the second AP and during the first portion of the TxOP, an indication of intent to participate in the MU transmission during the second portion of the TxOP, the indication of intent including a resource request of the second AP for participation in the MU transmission. The AP may transmit, during an initial period of the second portion of the TxOP, a trigger signal to the second AP indicating a set of one or more resources for the second AP during the MU transmission. The AP may participate, in conjunction with the second AP and during the second portion of the TxOP, in the MU transmission.

Abstract: In some implementations, a first access point (AP) selects one or more other APs for participation with the first AP in a coordinated access point transmission session. The first AP obtains a transmission opportunity (TXOP), and transmits a frame indicating scheduling information for uplink (UL) or downlink (DL) transmissions to or from the selected APs, the scheduling information indicating a respective start time for the UL or DL transmissions to or from the selected APs, at least two of the start times being offset from one another by a time period associated with decoding a preamble of a wireless packet. The first AP transmits or receives wireless packets to or from one or more associated stations (STAs) at least partially concurrently with the transmission or reception of wireless packets by the selected APs to or from their respective associated STAs based on the scheduling information.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

Abstract: This disclosure provides systems, methods and apparatuses for advertising discovery information of an AP in one or more downlink (DL) transmissions. In some implementations, the AP may allocate a dedicated resource unit (RU) for advertising discovery information of the AP to stations not associated with the AP, and may allocate one or more additional RUs for DL transmissions to one or more stations associated with the AP. The AP may transmit a multi-user (MU) packet containing discovery information intended for the unassociated stations and containing non-discovery-related information intended for the one or more associated stations. The discovery information may be transmitted on the dedicated RU, and the non-discovery-related information may be transmitted on the one or more additional RUs.
