Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, two devices may support signaling and messaging designs that support bandwidths that are greater than 160 MHz for ranging null data packets (NDPs). For example, various signaling and messaging designs may support a use of a 320 MHz bandwidth for ranging NDPs as part of a ranging measurement procedure, which may offer greater resolution than narrower bandwidths. The signaling and messaging designs may include one or more updates for a null data packet announcement (NDPA) frame, for a trigger frame, for session negation messages (such as one or both of an initial fine timing measurement (IFTM) frame and an IFTM request (IFTMR) frame), for segmentation techniques for ranging NDPs, or for any combination thereof.

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, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), an indication of a puncturing event. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the puncturing event. In certain aspects, the disclosure provides methods for transmitting and receiving, between the AP and one or more STAs, an indication of an operating band switch. In some examples, the transmitting and receiving may use non-legacy elements configured to provide information about the operating band switch.

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 use of a reinforcement learning (RL) model to obtain one or more parameters associated with a channel access procedure. Some aspects more specifically relate to mechanisms according to which a wireless communication device may receive information associated with the RL model and transmit a protocol data unit (PDU) during a slot that is based on an output of the model. The wireless communication device may use the RL model to perform a distributed channel access procedure in accordance with the information and may further transmit the PDU, during the slot that is based on the output of the RL model, in accordance with the distributed channel access procedure. The information associated with the RL model may indicate or configure the RL model or may indicate whether the wireless communication is allowed to retrain the RL model.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that operates in a wireless local area network may include an auxiliary radio and a main radio and may operate in both an auxiliary radio mode and a main radio mode. The auxiliary radio may support both transmitting and receiving or may support receiving only. The wireless device may indicate parameters associated with an auxiliary radio mode and/or with transitioning from the auxiliary radio mode to a main radio mode. The auxiliary radio may perform additional functions while the wireless device communicates with a second wireless device on a wireless link using the main radio. For example, the auxiliary radio may monitor channel metrics of the wireless link, receive and/or transmit control communications with the second wireless device, receive and/or transmit high importance data communications, or scan for and/or initiate connections via other wireless channels.

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, devices and systems for generating enhanced trigger frames. Some implementations more specifically relate to trigger frame designs that support gains in data throughput achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an enhanced trigger frame may be used to solicit a non-legacy trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) from one or more wireless stations (STAs). In some implementations, the enhanced trigger frame may be configurable to support multiple versions of the IEEE 802.11 standard. For example, an enhanced trigger frame may be configured in accordance with a legacy trigger frame format or a non-legacy trigger frame format. Thus, when configured in accordance with the legacy trigger frame format, the enhanced trigger frame can also be used to a legacy TB PPDU from one or more STAs.

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.
