Abstract: Various aspects of the techniques, methods and devices described in this disclosure relate generally to achieving coexistence between WLAN and P2P networks, and specifically, to coordinated D2D communications. Some aspects particularly involve extending the capabilities of TWT elements transmitted by APs to support periodic reserved access windows during which D2D-enabled wireless devices are permitted to transmit direct wireless communications. Some other aspects relate to sharing time and frequency resources via CAP TDMA or CAP OFDMA techniques, and specifically, to allocating at least some of the time and frequency resources specifically for D2D communications.

Abstract: This disclosure provides methods, devices and systems for synchronized channel access. Some implementations more specifically relate to facilitating coexistence among wireless communication devices that support synchronized channel access and those that do not. A group of access points may schedule periodically recurring, synchronized channel access periods by periodically transmitting quiet elements. The quiet elements establish recurring quiet periods during which legacy devices are not permitted to transmit. In some implementations, an access point may transmit one or more quiet override elements each associated with a respective quiet element and indicating to other access points supporting synchronized channel access that they are permitted to contend for access during the respective quiet period.

Abstract: This disclosure provides methods, devices, and systems for lightweight, low-latency authentication and association between STAs and APs in wireless local area networks (WLANs). In various aspects, an apparatus may transmit, over a WLAN prior to authentication by an access point (AP), a first Extensible Authentication Protocol Over a Local Area Network (EAPoL) frame including first information associated with an EAPoL protocol and second information associated with an encryption protocol. The apparatus may further receive, over the WLAN, a second EAPoL frame indicating successful authentication by the AP in accordance with the EAPoL protocol, the second EAPoL frame including third information associated with the encryption protocol.

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: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling parameters for peer-to-peer communications in a wireless network. One aspect provides a method for wireless communications at an access point (AP). The method generally includes: obtaining, from an access point (AP), a transmission opportunity (TXOP) sharing trigger indicating a duration in which a TXOP is shared by the wireless station and one or more other devices; relaying, to the one or more other devices, information identifying parameters for wireless communications between the wireless station and the one or more other devices; and during the TXOP, communicating with the one or more other devices based on the parameters for wireless communications between the wireless station and the one or more other devices.

Abstract: This disclosure provides methods, components, devices and systems for wireless packet header protection. Some aspects more specifically relate to supporting header integrity checks to prevent processing of maliciously altered packet headers. In some examples, a wireless communication device may generate header integrity check information based on one or more fields of a header of a first data packet. The wireless communication device may generate, based on the header integrity check information, the first data packet or a second data packet. For example, the header of the first data packet may include the header integrity check information, or a value derived therefrom. Alternatively, the header integrity check information (or the derived value) may be included in a subsequently transmitted packet (e.g., the second data packet) A receiving device may use the received header integrity check information to perform a header integrity check before processing the header of the first data packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a responding station may transmit a first ranging poll via a first bandwidth, the first ranging poll comprising an indication of a second ranging poll and first polling information transmitted with repetitions in a frequency domain based at least in part on serving first initiating stations (I-STAs) configured for communication using the first bandwidth and second I-STAs configured for communication using a second bandwidth that is smaller than the first bandwidth. The responding station may transmit, based at least in part on the indication of the second ranging poll, the second ranging poll over the second bandwidth comprising second polling information. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices, and systems for securing frames. In some examples, a frame is transmitted with a field that includes an identifier (ID) of a security key, a packet number (PN), and an integrity check based on one or more portions of the control frame and the security key. A device receiving the frame can verify the frame by calculating another integrity check based on the frame and the identified security key and comparing the calculated integrity check to the received integrity check.

Abstract: This disclosure provides methods, devices and systems for non-simultaneous transmit and receive (STR) station (STA) transmissions using multiple links. In one aspect, a medium synchronization delay timer associated with a second link of the non-STR STA can be initiated in response to completing transmission of the data on the first link to delay triggering of a clear channel assessment (CCA) associated with the second link. Data can be transmitted on the second link in response to expiration of the medium synchronization delay timer. In another aspect, an energy detect (ED) threshold level on a second link may be decreased from a first ED threshold level to a second ED threshold level after transmitting the data on the first link. In a further aspect, a block acknowledgment (BA) frame including a network allocation vector (NAV) synchronization of a second access point may be transmitted to the first link of the station.

Abstract: This disclosure provides methods, components, devices and systems for transmission opportunity (TXOP) sharing and resource allocation mechanisms in systems involving multiple peer-to-peer (P2P) sessions. Some aspects more specifically relate to how such mechanisms can facilitate multi-station (STA) TXOP sharing or STA offloading in accordance with relative resource availabilities across a set of access points (APs), or any combination thereof. In some implementations, an AP can allocate respective portions of a resource unit (RU) allocation (during a shared TXOP of the AP) to respective P2P sessions at multiple respective STAs. Additionally, or alternatively, an AP can use transmit power control to facilitate simultaneous TXOP sharing across multiple STAs. Additionally, or alternatively, first AP can offload a STA to a second AP in accordance with relative resource availabilities at the first AP and the second AP. As such, devices may achieve greater scalability for high-density P2P session deployments.

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 methods, devices and systems for communicating over multiple links, for example, indicating buffered units (BUs) per traffic identifier (TID) for transmission to multi-link devices (MLDs). One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method can be performed, for example, by a non-access point (non-AP) MLD. The non-AP MLD can receive an indication of an association identifier (AID) associated with the non-AP MLD, wherein the indication of the AID indicates whether an AP has BUs for the non-AP MLD, determine one or more links associated with one or more TIDs based on a mapping of a plurality of TIDs, including the one or more TIDs, to a plurality of links, including the one or more links, receive the BUs associated with the one or more TIDs from the AP on the determined links.

Abstract: This disclosure provides methods, components, devices and systems for link parameter recommendation in a wireless local area network. A first and second wireless communication device may communicate via one or more links. The second wireless communication device may use a first set of communication parameters to communicate with the first wireless communication device, and the first wireless communication device may determine that communication with the second wireless communication device using the first set of communication parameters fails to satisfy one or more criteria. Responsive to the determination, the first wireless communication device may transmit an indication for the second wireless communication device to use a second set of communication parameters for communicating with the first wireless communication device after which the first and second wireless communication device may communicate one or more frames.

Abstract: In some implementations, an access point (AP) establishes a restricted target wake time (TWT) session including at least one restricted TWT service period (SP) for peer-to-peer (P2P) communications. The AP admits a group of wireless stations (STAs) associated with P2P communications as members of the restricted TWT session, obtains a transmission opportunity (TXOP) on the wireless channel during the at least one restricted TWT SP, and transmits, on the wireless channel, a protection frame identifying one or more STAs of the group of STAs belonging to the restricted TWT session that are permitted to transmit or receive P2P communications on the wireless channel during the TXOP. The protection frame may also indicate to receiving devices other than the one or more identified STAs that the wireless channel is unavailable for at least a portion of the TXOP.

Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications. In one aspect, an apparatus may obtain, for a first access point (AP), a first service set identifier (SSID) associated with single-link communications and obtain, for a second AP, a second SSID associated with multi-link communications. The apparatus may obtain, from a wireless communication device, a management frame include a multi-link operation information field that carries a first SSID and obtain a multi-link indication for the wireless communication device based, at least in part, on the first SSID, the multi-link indication indicating whether the wireless communication device includes AP capable of link aggregation, and selectively associate with the wireless communication device based on the multi-link indication.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the “r-TWT link”). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.

Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.

Abstract: This disclosure provides methods, components, devices and systems for coordinated spatial reuse (C-SR) framework for ultra-high reliability (UHR). Some aspects more specifically relate to one or more mechanisms according to which access points (APs) may coordinate with each other in accordance with a C-SR framework. In some implementations, a first access point (AP) may conditionally share a transmission opportunity (TXOP) for the first AP with a second AP in accordance with an interference management procedure between the first AP (and any one or more client devices of the first AP) and the second AP (and any one or more client devices of the second AP). For example, the first AP and the second AP may support one or more frame exchanges associated with an interference measurement and the second AP may share the TXOP if the second AP satisfies a transmit power constraint associated with the interference measurement.
