    Abstract: A method performed by a multi-multi-link device (MMLD) architecture comprising a plurality of access points (APs) may comprise transmitting a frame, by an AP of the MMLD, wherein the frame may include a multi-multi-link device (MMLD) frame element which indicates that the AP is part of a multi-link device (MLD) that is a MMLD. The frame may comprise a beacon, short beacon, probe response, fast initial link setup (FILS) discovery frame, association response frame, or the like, or any appropriate combination thereof. The MMLD element may comprise one or more of an element identifier, length, MMLD identifier, MMLD media access control (MAC) address, partial reporting field, number of reported MLDs field and/or an MLD info field. The MLD may communicate with other MLDs of the multiple MLDs during a transmit wake time (TWT) service period (SP). The MLD may be in a doze state during non-TWT SPs.

    Abstract: Systems, methods, and devices for broadcast service negotiation and non-simultaneous transmit-receive (STR) channel blindness recovery are provided herein. Some methods performed by a Wireless Transmit/Receive Unit (WTRU), may comprise operating over a first link; operating over a second link; receiving a frame including a Network Allocation Vector (NAV) setting associated with the second link, the NAV setting indicating a time duration; and sending a transmission over the first link, wherein a duration of the transmission over the first link is shorter than or equal to the time duration indicated by the NAV setting. The frame including the NAV setting indicates that the time duration may not be extended or modified. The method may further comprise sending, by the WTRU, an indication that it the WTRU is capable of performing a multi-link restricted transmission. The WTRU may enter a sleep mode on the first link after sending the transmission over the first link.

    Abstract: Methods and apparatuses for privacy enhancement are provided herein. A method performed by a station, STA (201), may include transmitting, to an access point, AP (202), a first frame including information indicating that the STA (201) will use an over-the-air medium access control, otaMAC, address for a frame sent to the AP (202). The method may further include generating (210) a second frame for transmission to the AP (202) including a network MAC, nMAC, address of the STA (201), encrypting (211) the generated second frame, and replacing (212) the nMAC address with an otaMAC address either during the encryption or after the encryption. The method may further include transmitting (213) the encrypted second frame, including the otaMAC, to the AP (202), such that the AP (202) may replace (214) the otaMAC address with the nMAC address and decrypt (215) the second frame for forwarding via a distribution system, DS (203).

    Abstract: Methods and apparatuses are described herein for HARQ signaling and communications in wireless networks. For example, a method implemented in a STA comprises receiving a first MU transmission including a first set of HARQ bits, a first set of user data for STAs including the STA, a preamble including information indicating that the MU transmission includes the first set of HARQ bits, and a first set of HARQ Process IDs associated with the first set of HARQ bits; determining a subset of HARQ bits of the first set of HARQ bits; transmitting a response message indicating a reception status of the subset of HARQ bits; and receiving a second MU transmission including a second set of HARQ bits, a second set of user data for the plurality of STAs, and a second set of HARQ Process IDs associated with the second set of HARQ bits.

    Abstract: Methods and apparatuses are described herein for network discovery. A wireless transmit/receive unit (WTRU) may transmit, to a first access point (AP), via a Primary Connectivity Radio (PCR), a request indicating that on a condition that the WTRU is disassociated from the first AP, the WTRU will enter a wake-up radio (WUR) only discovery mode. The WTRU may receive, from the first AP, via the PCR, a management frame that has WUR discovery elements including an indication of at least one channel used by a second AP. The WTRU may perform disassociation from the first AP. The WTRU may activate a WUR and deactivate the PCR. On a condition that the WTRU is disassociated from the first AP, the WTRU may receive, from the second AP, via the WUR, a WUR frame over the at least one channel to enable the WTRU to activate the PCR to initiate association.

    Abstract: A method for use in a non-access point (AP) multi-link device (MLD), and a non-AP MLD are disclosed. In the method, the non-AP MLD transmits, by a first station (STA) affiliated with the non-AP MLD to a first access point (AP) affiliated with an AP MLD, on a first link, a request for AP assistance, including information regarding a second link for which assistance data is requested. Then, the non-AP MLD receives, by a second STA affiliated with the non-AP MLD from a second AP affiliated with the AP MLD, on the second link, a trigger frame.
