Abstract: This disclosure provides methods, components, devices and systems for addressing client constraints in dynamic subchannel operation (DSO). Some aspects more specifically relate to a DSO frame exchange between an access point (AP) multi-link device (MLD) and a non-AP MLD that is operating in accordance with an enhanced multi-link single-radio (EMLSR) or an enhanced multi-link multi-radio (EMLMR) communication mode. In such aspects, the non-AP MLD may use a frame associated with a DSO frame exchange to trigger the non-AP MLD to perform an operation associated with the EMLSR/EMLMR communication mode. Some additional, or alternative, aspects more specifically relate to a DSO frame exchange between an AP MLD and a non-AP MLD that has disabled a communication mode associated with uplink multi-user (MU) communication. In such aspects, the AP MLD and the non-AP MLD may apply one or more constraints on the DSO frame exchange associated with the disabled uplink MU communication.

Abstract: This disclosure provides methods, components, devices and systems for quality of service (QOS) based peer-to-peer (P2P) transmission opportunity grants. A first wireless communication device receives a first management message including a first stream identifier associated with a second wireless communication device. The first wireless communication device transmits a second management message to an access point, the second management message including a second stream identifier and an identifier of the second wireless communication device based on the first management message. The first wireless communication device receives a first control message associated with a shared transmission opportunity, the first control message including parameters that satisfy a set of QoS of the second wireless communication device, where the first control message enables the shared transmission opportunity for the second wireless communication device and a third wireless communication device.

Abstract: This disclosure provides methods, components, devices and systems for service period based coordinated spatial reuse. Some aspects relate to long term signaling to reduce the amount of signaling while achieving the gain associated with coordinated spatial reuse as compared to distributed spatial reuse. A first wireless device associated with a first basic service set (BSS) may transmit a beacon indicating a set of service periods designated for spatial reuse and an interference threshold. A second wireless device associated with a second BSS may receive the beacon and may communicate with one or more other wireless devices associated with the second BSS during the set of service periods designated for spatial reuse in accordance with the indicated interference threshold. Accordingly, the wireless devices in the second BSS may communicate at a power level that causes an acceptable level of interference at the first BSS.

Abstract: This disclosure provides methods, components, devices and systems for negotiation for coordinated medium access between wireless devices. Some aspects more specifically relate to techniques for negotiation between wireless devices for medium access. In some examples, wireless devices may transmit requests and responses to negotiate for conflicting medium access periods between wireless devices, where the wireless devices may be in different basic service sets (BSSs). For example, wireless devices such as wireless access points (APs) may broadcast a reservation of medium access periods. In some examples, a first wireless device may transmit a request to negotiate medium access periods with a second wireless device, and the second wireless device may transmit a response to the request. For example, the request to negotiate may request that the wireless devices mutually honor or respect (for example, comply with) one or more of the medium access period reservations of each wireless device.

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 provide mechanisms for conveying (critical) updates to a corresponding STA that is in an unassociated state. In some cases, a network entity may obtain an update during a communication session, such as a sensing measurement session. The network entity may then output a notification of the update to another wireless device. The network entity may also output the actual update itself.

Abstract: This disclosure provides methods, components, devices, and systems that support context acquisition for seamless roaming. Some aspects more specifically relate to segmenting a packet number (PN) space into subsets that are dynamically assigned to access points (APs) associated with a station (STA). In some implementations, a first wireless device (such as a STA) may communicate with a second wireless device (such as a serving AP) using a first subset of user data context parameters (such as a group or segment of PNs) that correspond to a first index assigned to the second wireless device. If, for example, the first wireless device decides to roam to a third wireless device (such as a target AP), the first wireless device may transmit one or more packets to the third wireless device using a second subset of the user data context parameters assigned to the third wireless device.

Abstract: This disclosure provides methods, components, devices, and systems that support sounding techniques for ultra-high reliability (UHR) communications. In some implementations, a first communication device may receive a null data packet announcement (NDPA) frame associated with a UHR NDPA variant type. The NDPA frame may include sounding information for communication devices that support UHR communications. The first communication device may receive a null data packet (NDP) in accordance with the sounding information, and may perform UHR communications based on measurements of the NDP. In some other implementations, the first communication device may receive a trigger frame that indicates the NDPA, a sounding mode for transmission of the NDP, and parameters for transmission of a compressed beamforming frame (CBF) associated with the NDP. The first communication device may transmit or receive the NDP in accordance with the sounding mode, and may receive or transmit the CBF using the parameters.

Abstract: This disclosure provides methods, components, devices and systems for Transmit Opportunity (TXOP) Sharing (TXS) enhancements. In some cases, a wireless node may transmit a first frame that includes a request for a network allocation vector (NAV) setting associated with a shared transmission opportunity (TXOP), receive a second frame triggering the shared TXOP, and communicate, during the shared TXOP, with the NAV set in accordance with the request.

Abstract: This disclosure provides methods, components, devices and systems for operation expansion policy framework for access points (APs). 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.
