Abstract: Systems, methods, and mechanisms for WLAN enhancements to facilitate co-existence with other radio access technologies, such as Bluetooth, 5G NR, and/or UWB. For example, WLAN transmissions may be shortened, e.g., to better fit within available transmission times. A wireless device may shorten WLAN transmissions of a peer device by specifying a frame size limitation for WLAN communications. The frame size limitation may be indicated via a data frame, a management frame, a beacon frame, an association request frame, and/or an association response frame.

Abstract: Embodiments are disclosed for group cast with retries (GCR) in a multi-link wireless communications system. In some embodiments, an access point (AP) multi-link device (MLD) can exchange information with a non-AP MLD to establish a GCR-multi-link operation (MLO) agreement corresponding to a group address, wherein the information includes, but is not limited to: a GCR primary link or a GCR primary link set of the AP MLD, an association identifier (AID) that corresponds to the group address. In some embodiments, the AP MLD can transmit a GCR frame subject to the GCR-MLO agreement, where the GCR frame includes a sequence number assigned from sequence number space (SNS)_GCR_MLO defined at a MLD level, and generate a Group Temporal Key (GTK)_GCR_ML at the MLD level, where the GTK_GCR_ML enables encryption and decryption of the GCR frame.

Abstract: An electronic device that performs a scan is described. During operation, the electronic device may perform, using a scanning radio, the scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon associated with a second electronic device, where the beacon includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Abstract: This disclosure relates to transmitting multicast information over a network, such as a wireless local area network (WLAN). A source device may transmit a multicast and a request for feedback to a plurality of sink devices. The sink devices may transmit feedback based on whether they successfully decoded the multicast. The source device may retransmit the multicast (or a portion thereof) based on the feedback.

Abstract: An interface circuit in an electronic device (such as an access point) may utilize a configurable wake-up-frame format. During operation, the interface circuit may receive a wake-up-radio (WUR)-setup request associated with a recipient electronic device, where the WUR-setup request specifies a proposed configurable wake-up-frame format. In response, the electronic device may determine the configurable wake-up-frame format to be used based at least in part on the proposed configurable wake-up-frame format. Then, the interface circuit may provide a WUR-setup response intended for the recipient electronic device, where the WUR-setup response specifies the configurable wake-up-frame format selected for use. Note that the configurable wake-up-frame format may specify a payload length in a wake-up frame and/or one or more operations of at least one of the recipient electronic device or the electronic device after the wake-up frame is transmitted by the electronic device.

Abstract: An electronic device may coordinate access to a shared communication channel with one or more other electronic devices. After receiving frames from the one or more other electronic devices with information specifying back-off values associated with at least an access category for the one or more other electronic devices in a subsequent potential slot transmission opportunity, the electronic device may update a stored list of known occupied back-off values for the subsequent potential slot transmission opportunity. Then, the electronic device may select and may transmit to the one or more other electronic devices an available back-off value for the electronic device in the subsequent potential slot transmission opportunity that is not included in the stored list and that is associated with an access category. Next, during a slot corresponding to the selected back-off value, the electronic device may transmit a second frame to at least another electronic device.

Abstract: An interface circuit in a device, e.g., an access point, may perform link adaptation. During operation, the interface circuit may provide a wake-up frame, e.g., a LP-WUR packet, associated with a channel in a band of frequencies, where the wake-up frame is intended for a wake-up radio in a recipient device. Then, the interface circuit may receive, from the recipient device, feedback information associated with a second channel in a second band of frequencies, where the feedback information is associated with a main radio in the recipient device. Based at least in part on the feedback information, the interface circuit may estimate one or more communication metrics associated with the channel in the band of frequencies. Moreover, based at least in part on the one or more communication metrics, the interface circuit may determine a data rate for use in communication via the channel in the band of frequencies.

Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). The access point receives, from one or more electronic devices in a set of electronic devices, one or more requests to send data. In response, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices. After receiving a frame from the last electronic device in the ordered list of electronic devices or after an unused transmit opportunity of the last electronic device in the ordered list of electronic devices, the access point transmits a block acknowledgment to the ordered list of electronic devices.
