    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.

    Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing block acknowledgment (BA) operations for multi-link wireless communication networks. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors transmit, using the transceiver and to a second electronic device, a first set of one or more frames on a first link and a second set of one or more frames on a second link. The one or more processors receive, using the transceiver and from the second electronic device, a first block acknowledgment (BA) frame on the first link and a second BA frame on the second link. The one or more processors further determine, based on received first BA frame and the second BA frame, a failed or missing frame of the first set of one or more frames transmitted on the first link.

    Abstract: An interface circuit in an electronic device (such as an access point) may receive a setup request associated with the recipient electronic device. The setup request may specify a group address for which the recipient electronic device wants to receive associated frames and a proposed transmission interval. Based at least in part on the proposed transmission interval, the electronic device may determine a transmission schedule and/or may assign, based at least in part on the group address, the recipient electronic device to an aggregated group having a flexible multicast service identifier (FMSID). Then, the electronic device may provide a wake-up frame for the recipient electronic device, where the wake-up frame includes an identifier of the aggregated group for which a group-addressed frame will subsequently be transmitted by the electronic device. Moreover, the wake-up frame may be provided at a transmission time based at least in part on the transmission schedule.

    Abstract: During operation, an electronic device may encrypt an A-control subfield. Then, the electronic device may provide the frame addressed to a second electronic device, where the frame includes a media access control (MAC) header and the MAC header includes the A-control subfield that is encrypted. Note that the encrypted A-control subfield may be jointly encrypted with data in a payload in the frame. Moreover, the encrypted A-control subfield may be separated from the payload in the frame by one or more additional subfields or may be adjacent to the payload in the frame. Furthermore, the MAC header may include an indicator that indicates whether the A-control subfield is encrypted. Additionally, the frame may include a preamble that indicates whether the A-control subfield is encrypted. The frame may be received by the second electronic device. After receiving the frame, the second electronic device may decrypt the A-control subfield.

    Abstract: Embodiments described herein relate to a system and method for providing flexible receiver configuration in wireless communication systems, such as 802.11 WLAN systems. In one embodiment, a wireless device may transmit a first data frame including first configuration information specifying a first configuration of the receiver to notify a remote device that the wireless device intends to configure its receiver according to the first configuration. After receiving an acknowledgement frame confirming the first configuration information, the wireless device may configure the receiver according to the first configuration. In another embodiment, a wireless device may receive a first data frame including first configuration information and further including a request that the wireless device configure its receiver according to the first configuration. In response, the wireless device may configure the receiver according to the first configuration. In either case, the wireless device may receive subsequent communications according to the first configuration.
