    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: 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: 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 methods, components, devices, and systems for reconfiguring link characteristics while maintaining links. Some aspects more specifically relate to a first and second wireless communication device establishing a plurality of wireless communication links that are based on or associated with a set of characteristics such as capabilities of the first and second wireless communication devices and association parameters. The first wireless communication device may transmit, to the second wireless communication device, a request to update one of the characteristics while maintaining each wireless communication link of the plurality of wireless communication links. The second wireless communication device may transmit a response to the request that includes an indication about updating the characteristic. Then if the response includes an indication to update the characteristic, the first and second wireless communication devices may communicate according to the updated characteristic.

    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 apparatuses for wireless communication that can be used for channel puncturing. A wireless station (STA) may receive an indication of a first puncturing pattern to be used for transmitting or receiving data over a wireless channel, where the first puncturing pattern is defined by a first wireless communication protocol release and the STA is configured to operate according to a second wireless communication protocol release. The STA may select, from a set of puncturing patterns defined by the second wireless communication protocol release, a second puncturing pattern that includes one or more non-punctured subchannels that are subsets of one or more corresponding non-punctured subchannels of the first puncturing pattern. The STA may use the second puncturing pattern to transmit or receive one or more packets over the wireless channel.
