Abstract: The present disclosure provides methods and apparatus related to NDPA frame indication. An aspect of the disclosure provides a method. The method includes sending, to one or more stations (STAs), a request for channel state information (CSI). The request includes a null data packet announcement (NDPA) frame including a first field and a second field. The first field indicates presence of the second field, and the second field indicates a variant of the NDPA frame. The method further includes receiving, from the one or more STAs, a CSI feedback response based on the request. In some embodiments, the first field is one of a sounding dialog token field and indicates the presence of the second field via at least two bits. In some embodiments, the first field is a frame control field and indicates the second field via a 4-bit subtype subfield.

Abstract: An aspect of the disclosure provides a method of communication between a first multi-link device (MLD) and a second MLD, the first MLD being affiliated with a first station (STA) and a third STA, the second MLD being affiliated with a second STA and a fourth STA. Such a method includes receiving, by the first multi-link device (MLD) from the first station (STA), a management frame comprising a header indicating address information associated with the second MLD. Such a method further includes encrypting, by the first MLD, the management frame based on a security association established between the first MLD and the second MLD. Such a method further includes sending, by the first MLD, the encrypted management frame toward the second MLD via one of the first STA and the third STA.

Abstract: The present disclosure relates to multi-link devices (MLDs) including access point (AP) MLDs and non-AP MLDs, and specifically modules, systems and methods for changing a first communication link between a first affiliated station (STA) of a non-AP MLD and a first affiliated AP of an AP MLD to a second communication link between the first affiliated STA of the non-AP MLD and a second affiliated AP of the non-AP MLD, while maintaining a third communication link between a second affiliated STA of the non-AP MLD and a third affiliated AP of the AP MLD. More specifically, the present disclosure provides modules, systems and methods for changing an association of a communication link independent of other communication links allowing for continuous connectivity between a non-AP MLD and an AP MLD.

Abstract: A direct link addressing method and apparatus. Direct communication is performed between a non-AP MLD and a non-AP MLD, or between a STA device and a non-AP MLD, thereby improving data transmission efficiency. The method is applied to a first device, and the first device includes one or more stations STAs. The first device is connected to a third device, and the third device includes a plurality of access points APs. A second device is connected to the third device, and the second device includes a plurality of STAs. The first device transmits a first data unit over a direct link between the first device and the second device, thereby increasing a data transmission rate.

Abstract: Efficient and accurate sensing measurements and reporting with multiple responders in 60 GHz WLAN is accomplished by conducting the measurements and reporting in multiple sub-channels separated in a frequency domain, or in a space domain, or both. Measurements, via sensing PPDUs, can be transmitted in parallel in time by multiple devices. Messaging related to communicating reporting of sensing results can also be transmitted in parallel in time by multiple devices. This parallelization is facilitated by the use of the multiple sub-channels in frequency or spatial domain.

Abstract: The present disclosure provides for methods, systems and apparatus related to WLAN enhanced channel map advertisements. An aspect of the disclosure provides for a method for discovering a network. The method includes sending a discovery request to an access point for discovering a network, the discovery request requesting for: available channels of access points within a radio range of the device, one or more access network operators for the available channels, and one or more service providers for the available channels. The method further includes receiving from the access point a response message including one or more lists indicative of: the available channels, the one or more access network operators, and the one or more service providers. In some embodiments, the response message is based on one of: internal data of the access point, and databases indicative access network operators and service providers.

Abstract: Systems and methods for WLAN multi-link TDLS key derivation. An aspect of the disclosure provides a method for WLAN multi-link communication. Such a method includes sending, by a first station to a second station, a discovery request comprising a link identifier indicating a non-access point (AP) multi-link device (MLD), wherein the first station and the second station are associated with an AP MLD. Such a method further includes receiving, by the first station from the second station, a discovery response. In some embodiments, the method further includes receiving, by the first station from an AP affiliated with the AP MLD, a message indicating a MAC address of the second station. In some embodiments, the discovery request is sent via an AP affiliated with the AP MLD and a non-AP station affiliated with the second station.
