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: 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: Methods, systems, and devices for wireless communications are described. A first wireless device and a second wireless device (e.g., access points, stations) may support transmission opportunity (TXOP) sharing procedures. The second wireless device may transmit a frame indicating a capability of the second wireless device to support one or more triggered TXOP sharing modes. The second wireless device may transmit an indication (e.g., a frame) indicating to change support for the triggered TXOP sharing modes based on the capability. The change may indicate to suspend, resume, disable, or enable the triggered TXOP sharing modes. For example, the second wireless device may transmit an indication to suspend support of a first triggered TXOP sharing mode that enables the second wireless device to perform peer-to-peer transmissions. Accordingly, the first wireless device may trigger the second wireless device to communicate according to the supported triggered TXOP sharing modes.

Abstract: A transmitting (Tx) access point (AP) multi-link device (MLD) may be configured to designate a parent ML element and at least one child ML element in the network management frame, e.g., the beacon frame or probe response frame, and at least one non-AP MLD may be configured to receive the network management frame and apply the parent ML element to the child ML element.

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: 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: Methods, systems, and devices for wireless communications are described. A first device may receive signaling associated with a traffic class from a second device. The first device may determine that the traffic class is included in a set of known traffic classes based on a set of features associated with the signaling. In response to determining that the traffic class is included in the set of known traffic classes, the first device may use a machine learning model to obtain a prediction of an application associated with the signaling. The prediction may be based on the set of features. The machine learning model may be trained at the first device or the second device. The first device may receive information associated with the machine learning model from the second device.

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.
