    Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

    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: 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: 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.
