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: A multilink access point may communicate with a legacy device. The multilink access point identifies an attempt, by at least one legacy station, to connect to the access point, determines that the at least one legacy station does not support multilink communications, broadcasts a beacon identifying information for a basic communication link that can be used by the at least one legacy station and associates with the at least one legacy station based at least on information included in the beacon, wherein the at least one legacy station communicates exclusively on the basic communication link with the access point.

Abstract: A wireless device may transmit ranging transmissions using a compressed PSDU. The compressed PSDU may be configured to support poll packets, response packets, and report packets. The compressed PSDU may comprise an identifier (ID) field, an address field, ID specific data, and a cyclic redundancy check (CRC) field. Further, the wireless device may use an optimized header IE for broadcast.

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 transmission preemption in a wireless local area network. An access point wireless device may establish a wireless association with another wireless device. A first data transmission may be initiated. The transmitting wireless device may determine to preempt the first data transmission prior to its completion. The transmitting wireless device may transmit signaling indicating that the first data transmission is preempted.

Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.

Abstract: Multiuser (MU) Multi-TID (multi-traffic-identifier) transmission may be enabled in a resource unit (RU). To transmit an urgent payload as soon as possible, the urgent payload may be injected/included into the ongoing MU physical protocol data unit (MU PPDU), if possible. This may be accomplished by indicating to the latency-sensitive wireless station (STA) the ID of a companion (or buddy) station that has an assigned resource unit (RU) on which the STA may expect to receive the urgent payload, also referred to as the “overloaded RU.” Alternatively, an extra user field in the preamble of the MU PPDU may be used to indicate to the STA its station ID as well as the location of the overloaded RU. A receiver operating on an A-MPDU may select the RU it receives, and may identify (or determine) a wrong transmission based on the transmitter address.

Abstract: This disclosure relates to methods for multi-access point association in a wireless local area network. Multiple access point wireless devices may establish a multi-access point system. Other access point wireless devices may subsequently join the multi-access point system. Non-access point wireless devices may form an association with the multi-access point system, which may include links with multiple different access point wireless devices in the multi-access point system.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing backup link establishment and operation for multi-link wireless communication networks such as a wireless local area network (WLAN). Some aspects relate to an electronic device including a transceiver configured to communicate over a wireless network and a processor communicatively coupled to the transceiver. The processor receives a message including information associated with a backup link from a second electronic device. The processor further receives data associated with data traffic from the second electronic device on a primary link of the wireless network. In response to a quality of the primary link being below a threshold, the processor receives a notification frame from the second electronic device on the backup link and receives additional data associated with the data traffic from the second electronic device on the backup link or on an other link informed by the notification frame.

Abstract: Some embodiments include utilizing a multilink media access control (MAC) address structure to support multilink devices (MLDs) that can operate concurrently in more than one link such as extremely high throughput (EHT) access points (APs) and EHT stations (STA), where the multilink MAC address structure is compatible with legacy devices. An EHT AP can utilize a multilink basic service set (BSS) identification (BSSID) MAC address to communicate with an EHT STA identified by a multilink MAC address. Values of the multilink BSSID and the multilink MAC address of the EHT STA are independent of which of the multiple links are used in the communication. In addition, to utilizing a multilink BSSID, the EHT AP can also support unique link-specific MAC addresses to concurrently support legacy and MLD stations. The EHT STA can also utilize unique link-specific MAC addresses that can be different than the EHT AP's link-specific MAC addresses.

Abstract: Embodiments are disclosed for one-to-many and many-to-many ranging using narrowband assisted (NBA)-multi-millisecond (MMS) ultra wideband (UWB) protocols. Some embodiments include an initiator device that communicates with many responder devices. For example, the initiator device can transmit a control/initialization poll message via NB signaling that identifies a ranging cycle, and transmit a first set of MMS segments corresponding to the control/initialization poll message. The initiator device can receive a plurality of report frames from two or more responder devices via NB signaling subsequent to transmitting the first set of MMS segments, and transmit within the ranging cycle, a ranging results report message based at least on the plurality of report frames via narrowband signaling.

The MLD also includes a second STA associated with a second link of the wireless network. The second STA is in a hibernation mode. The MLD also includes one or more processors communicatively coupled to the first and second STAs and configured to control operations of the first and second STAs.
