    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: 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: 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: Some embodiments of this disclosure include apparatuses and methods for implementing a queuing latency aware buffer status report (BSR). 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 determine an amount of data queued in a buffer for transmission over the wireless network and determine latency information associated with the queued data. The one or more processors generate a queuing latency aware buffer status report (BSR) based at least on the determined latency information. The electronic device transmits the queuing latency aware BSR to an access point.

    Abstract: An electronic device that communicates frames is described. During operation, the electronic device may transmit the frames addressed to a recipient electronic device and associated with multiple links between the electronic device and the recipient electronic device. Then, the electronic device may receive block acknowledgments for at least a subset of the frames, where a given block acknowledgment is associated with the recipient electronic device and indicates received frames on a given link in the links. Moreover, the electronic device may control an amount of traffic conveyed on the links based at least in part on the block acknowledgments. Next, the electronic device may store a remainder of the frames based at least in part on the block acknowledgments, where the frames include the subset of the frames and the remainder of the frames. Note that the frames may have a common traffic identifier.

    Abstract: This disclosure relates to methods for conducting multilink communications between a user equipment device (UE) and a wireless access point (AP) over a wireless local area network (WLAN). The UE establishes a connection with an access point through a WLAN, wherein the connection utilizes a plurality of links. The UE transmits an indication to the access point through a first link of the plurality of links, where the indication specifies one or more available links of the plurality of links that are available for the UE to receive downlink (DL) communications from the access point. The UE receives one or more DL communications from the access point through at least one of the one or more available links.
