    Abstract: Systems, methods, and mechanisms for an out-of-band (OOB) ultra-wide band (UWB) channel arbitration and/or channel coordination scheme. A device may transmit, periodically, an advertisement packet on an advertisement channel associated with a UWB channel. The device may transmit, according to a UWB channel usage pattern indicated by the advertisement packet, on the UWB channel. The advertisement packet may include a UWB transmit start time offset, a UWB transmit duration, a UWB transmit interval, information to determine a UWB transmit interval, and/or a UWB transmission type.

    Abstract: Methods, systems and apparatuses for negotiating mapping between traffic flows and different links by an access point (AP) multi-link device (MLD) and non-AP MLD are described. An AP MLD may transmit an initial request for a first limited mapping. A non-AP MLD may change to the first limited mapping. The non-AP MLD may register one or more high priority traffic flows and may change to a second mapping accommodating the high priority traffic flows on at least one additional link. The non-AP MLD and AP MLD may additionally exchange second and final mapping negotiation messages.

    Abstract: Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A station may communicate with a legacy BSS of a wireless network to transition to a PE BSS of the wireless network. The station may receive, from the PE BSS of the wireless network, an encrypted beacon, wherein the encrypted beacon is decoded based on information received from the legacy BSS and perform, with the PE BSS of the wireless network, an encrypted handshake procedure to authenticate and associate with the PE BSS of the wireless network.

    Abstract: Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A non-associated PE station may receive, from a PE access point, one or more discovery beacons advertising PE BSSs hosted by the PE access point and transmit, to the PE access point, a request to setup pre-association security protection. The non-associated PE station may, upon setup of pre-association security protection, transmit, to the PE access point, a protected request frame and receive, from the PE access point, a protected response that includes PE access point parameters.
