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.

Abstract: This disclosure provides methods, components, devices and systems for signaling mechanisms for low latency and low complexity relay designs. Some aspects more specifically relate to an end-to-end (E2E) relay framework according to which a satellite access point (AP) may relay one or more protocol data units (PDUs) and a block acknowledgment (BA) associated with the one or more PDUs between a client device and a root AP within a single transmission opportunity (TXOP). In some implementations, the satellite AP may refrain from performing operations associated with reordering and retransmitting as part of the relay. In some other implementations, the satellite AP may perform some amount of retransmissions in accordance with a time duration of the TXOP. The root AP, the satellite AP, and the client device may support an end-to-end encryption of both the set of PDUs and the BA associated with the set of PDUs.

An access point (AP) may transmit two or more physical layer protocol data units (PPDUs) that are duplicates of each other while operating in a duplicate data packet mode. A station (STA) may include one or more decoders configured to decode the duplicate PPDUs cumulatively or separately based on a decoding mode. The AP and the STA may exchange frames to dynamically enable or disable the duplicate data packet mode. The duplicate PPDUs may include one or more bits configured to indicate that the PPDU is a duplicate. The STA may decode at least one of the duplicate PPDUs and transmit a feedback message responsive to at least a portion of one of the duplicate PPDUs.

Abstract: This disclosure provides methods, components, devices, and systems that support techniques for multi-primary channel access. Some aspects more specifically relate to providing assistance information to a first wireless device that supports multi-primary channel access. In some examples, the first wireless device may receive the assistance information from a second wireless device via a first channel. The assistance information may include a first indication to assist the first wireless device with accessing a second channel for the purpose of communicating with a third wireless device. In some implementations, the first indication may provide the first wireless device with timing information, bandwidth-related information, STA service information, synchronization information, transmit opportunity (TXOP) sharing information, or a combination thereof.

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, components, devices and systems for techniques for coordinated medium access for ultra-high reliability. Some aspects more specifically relate to access point (AP)-to-AP coordination via, for example, one or more management frames. In some implementations, a wireless communication device may coordinate timing information with one or more other APs and may inform a set of stations (STAs) of the coordinated timing information, where a configured set of identifiers (IDs) may be used to differentiate which timing information pertains to which AP and inform how the set of STAs are expected to parse the coordinated timing information. Additionally, or alternatively, wireless communication devices may exchange one or more public action frames to facilitate AP-to-AP coordination, where such one or more public action frames may be specifically associated with providing information pertaining to coordinated medium access.

Abstract: This disclosure provides systems and methods for requesting wireless resources for peer-to-peer (P2P) communications. In some implementations, a wireless communication device transmits a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header carrying a request for the AP to allocate part of a transmission opportunity (TXOP) for P2P communications between the wireless communication device and a client device. The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QOS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.

An example method, performed by a first wireless node, includes outputting, for transmission, information that indicates at least one of (i) one or more criteria that, when met by a second wireless node, indicate the second wireless node is allowed to request that the first wireless node modify one or more wireless operating parameters, or (ii) one or more options for modifying the wireless operating parameters of the first wireless node, obtaining a first request that requests the first wireless node to modify the wireless operating parameters, and processing the first request based on the information.

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, components, devices and systems for performing actions to reduce end-to-end latency during a transmission of an encrypted payload of a medium access control (MAC) protocol data unit (MPDU) from a root access point (AP) to a wireless station (STA) via a satellite AP. For example, the satellite AP may be configured to receive the encrypted payload from the root AP, and then forward the received encrypted payload to the wireless STA, without decrypting the received encrypted payload and re-encrypting unencrypted payload at the satellite AP.

Abstract: This disclosure provides methods, components, devices and systems for channel access techniques in a multi-hop framework for ultra-high reliability (UHR).

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 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.
