摘要： An access point (AP) may operate as a master AP (AP1) to perform multi-AP coordinated beamforming (CBF). The AP1 may to initiate a first sounding sequence with one or more STAs associated with the AP1 (BSS STAs) and the one or more STAs associated with a second AP (AP2) (OBSS STAs). In these embodiments, initiation of the first sounding sequence triggers the AP2 to join the sounding sequence to initiate a second sound sequence with the BSS STAs and the OBSS STAs.

摘要： Embodiments of a multi-link access point (AP) device, station (STA) and method of communication are generally described herein. The multi-link AP device may comprise multiple APs. The multi-link AP device may encode a frame for transmission by one of the APs of the multi-link AP device. The multi-link AP device may encode the frame to include signaling to enable multi-link discovery of the APs of the multi-link AP device. The multi-link AP device may encode the signaling to include: a reduced neighbor report (RNR) element that identifies the APs of the multi-link AP device, and a multiple AP element. The multiple AP element may be configurable to include: common information for the APs of the multi-link AP device, and per-AP sub-elements that include per-AP information related to the APs of the multi-link AP device.

摘要： An access point station (AP) configured for wireless local area network (WLAN) sensing may be configured to perform a sensing measurement setup with a non-AP station (non-AP STA). The sensing measurement setup may comprise an exchange of sensing measurement request and response frames to establish sensing measurement parameters for one or more sensing measurement instances including trigger-based and non-trigger based sensing measurement instances. The AP may perform sensing measurements with the non-AP STA by transmitting and/or receiving one or more null-data packets (NDPs) for a sensing measurement instance. The NDPs may be configured in accordance with the sensing measurement parameters. For performing a non-trigger based sensing measurement instance when the AP is operating a sensing responder and when reporting was indicated in a sensing measurement setup request frame received from the non-AP STA, the AP may encode a sensing measurement report for transmission to the non-AP STA.

摘要： This disclosure describes systems, methods, and devices related to responder-to-responder Wi-Fi sensing between station devices. A device may cause to send, during a trigger frame sounding phase of a responder-to-responder Wi-Fi sensing, a sensing responder-to-responder sounding trigger frame to the first station device and the second station device, the sensing responder-to-responder sounding trigger frame associated with causing the first station device to send a responder-to-responder null data packet (NDP) to the second station device; cause to send, during a reporting phase of the responder-to-responder Wi-Fi sensing, a sensing report trigger frame to the second station device; and identify, during the reporting phase, a sensing measurement report from the second station device based on the sensing report trigger frame, wherein the sensing measurement report is indicative of measurements of the responder-to-responder NDP.

摘要： This disclosure describes systems, methods, and devices related to fast transition Wi-Fi roaming operations. A device may generate, during a first association of the device to a first access point, a request to authenticate the device to a second access point; send, during the first association, the request to authenticate; receive, during the first association, a response indicating that the device is authenticated to the second access point; generate, during the first association, a reassociation request to the second access point; determine that a time between sending the request to authenticate and generating the reassociation request is less than a threshold time; send, based on the determination that the time is less than the threshold time, the reassociation request to the second access point; and receive a reassociation response indicative of a second association of the device to the second access point.

摘要： This disclosure describes systems, methods, and devices related to multi-AP resource sharing. A device may participate in a set of coordinated access points (APs) for coordinating a sharing of one or more resources. The device may evaluate whether there is data to be transmitted to at least one associated station device. The device may, based on the evaluation, perform an action associated with acquiring a first transmit opportunity (TXOP) to be shared with one or more candidate APs of the set of coordinated APs.

摘要： This disclosure describes systems, methods, and devices related to a time division duplex (TDD) antenna sector switch. A device may determine one or more antenna sector configurations based on TDD beamforming, wherein the one or more antenna sector configurations are associated with first antenna sectors used to communicate with a first station device (STA). The device may initiate a TDD sector switch with the first STA to switch from the one or more first antenna sectors to one or more second antenna sectors. The device may cause to send, to the first STA, an action frame comprising TDD sector setting parameters associated with the TDD sector switch. The device may identify a response frame received from the first STA, wherein the response frame comprises the TDD sector setting parameters. The device may perform the TDD sector switch by switching from the one or more first antenna sectors to the one or more second antenna sectors.

摘要： This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.
