Abstract: An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.

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, including computer programs encoded on computer-readable media, for reporting Quality of Service (QoS) feedback information. A method of wireless communication at an apparatus may include selecting, from a variable number of control fields, one or more control fields for inclusion in a frame, each control field comprising a control identifier field and a control information field. The control identifier field may include an indicator indicating a type of information for communication is QoS feedback information. The control information field may include one or more subfields containing the QoS feedback information. The method may further include generating the frame comprising the selected number of control fields, and outputting the frame for 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: Certain aspects of the present disclosure relate to wireless communications and, more particularly. A method that may be performed by an access point (AP) includes obtaining, while communicating with at least one station on a first set of channels, information regarding a second set of channels not being currently used by the AP and outputting, for transmission, an off-channel indication that identifies one or more of the second set of channels that are available to the at least one station for peer-to-peer (P2P) communications with at least one other station.

Abstract: A wireless station (STA) operating as a non-simultaneous transmit-receive (NSTR) soft access point (AP) multi-link device (MLD) is associated with a primary link and a non-primary link. The NSTR softAP MLD transmits, on only the primary link, a frame including a complete profile of the primary link and indicating a complete profile of the non-primary link. The respective complete profiles of the primary link and the non-primary link each include capabilities, operation parameters, and other discovery information. The frame can include fields and elements that carry the complete profile of the primary link, and can include a multi-link (ML) element that indicates the complete profile of the non-primary link. The NSTR softAP MLD can receive or determine an update to the operation parameters of the non-primary link, and can transmit, on the primary link, an indication of the update to the operation parameters of the non-primary link.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

Abstract: This disclosure provides systems, methods, and apparatuses for allocating wireless resources to a multiple basic service set identifier (BSSID) set including a number of BSSIDs each associated with a corresponding one of a number of access points (APs). An AP may allocate random access resources for use by stations belonging to the multiple BSSID set using a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element. The AP may transmit a trigger frame containing the number of AID values to the stations belonging to the multiple BSSID set.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver device may receive a management frame addressed to the receiver device; parse the management frame to identify a link identifier included in the management frame; associate the link identifier with link information included in the management frame; and update, based at least in part on the link information, a communication configuration for a link identified by the link identifier. Numerous other aspects are provided.
