Abstract: Aspects relate to multi-link communication. In some examples, a communication frame carries a multi-link information element (ML IE). The ML IE includes a bitmap and one or more information sub-elements. In some examples, the bitmap indicates the links of a set of radio links to which the information sub-elements apply. In some examples, a frame may carry multiple ML IEs. In some examples, different ML IEs in the same frame may include the same bitmap, where the different ML IEs may carry different information sub-elements for the radio links indicated by the bitmap. In some examples, an ML IE serves to indicate that information sub-elements that are located in the frame body of the frame at a location that precedes the ML IE in the frame body apply to different radio links than the radio links indicated by the bitmap of the ML IE.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication performed by a wireless communication device. An example wireless communication device includes an access point (AP) multi-link device (MLD). The AP MLD transmits a beacon frame to a wireless station (STA) MLD, the beacon frame including a plurality of AP medium access control (MAC) addresses of respective APs belonging to the AP MLD. The AP MLD receives an association request from the STA MLD, the association request including a plurality of STA MAC addresses of respective STAs belonging to the STA MLD. The AP MLD generates, during a handshake operation with the STA MLD, one or more encryption keys configured to encrypt communications between the AP MLD and the STA MLD. The AP MLD verifies the plurality of STA MAC addresses based at least in part on the one or more encryption keys.

Abstract: This disclosure provides methods, devices and systems for reducing beacon bloat, inefficient spectrum use, and coupling of multi-link transmission element (MLTE) with a traffic indication map (TIM) element. In certain aspects, an MLTE may be transmitted by an access point (AP) multi-link device (MLD) in a frame separate from the beacon frame to reduce the size of the beacon frame. In such an example, the beacon frame may provide an indication to a non-AP MLD that is should remain awake to receive data. In certain aspects, the AP may transmit multiple MLTEs to reduce the amount of bandwidth used for MLTE transmission by cutting out non-AP MLDs and other stations (STAs) that do not have buffered data. In certain aspects, the AP may assign each non-AP MLD capable of transmission identifier (TID)-to-link mapping (TID2LM) with a per-link traffic indication bitmap (PLTIB) to decouple the MLTE from the TIM element.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for protecting latency-sensitive communications among multi-link devices (MLDs). An access point (AP) MLD may establish multiple communication links with a non-AP MLD and schedule a restricted target wake time (r-TWT) service period (SP) on one of the links (the “r-TWT link”). In some aspects, when a transmit opportunity (TXOP) acquired on a non-r-TWT link overlaps the r-TWT SP, the TXOP may be extended to support an exchange of latency-sensitive traffic on the non-r-TWT link. In some other aspects, any TXOPs occurring on non-r-TWT links may be terminated prior to the start of the r-TWT SP so that latency-sensitive traffic can be exchanged on the r-TWT link during the SP. An AP MLD also may schedule SPs on multiple communication links. In some aspects, the AP MLD may transfer a TWT agreement between the communication links.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a device may transmit, via a broadcast, a first frame that indicates one or more of a device credential or a payload. The device may receive, from the access point, a second frame that indicates one or more of the payload or an access point credential. The device may associate with the access point based at least in part on the access point credential. The device may perform a communication, to a cloud computing system via the access point, after the device has been associated with the access point. Numerous other aspects are described.

Abstract: Aspects of the present disclosure generally relate to wireless communications and, more particularly, to techniques for managing multi-link communications. Some aspects of the present disclosure provide techniques for configuring data unit and control response transmissions on multiple links. The data unit and control responses may be configured such that a control response transmission does not overlap with a data unit reception at a station that is without simultaneous transmission and reception capability.

Abstract: This disclosure provides systems, methods and apparatuses for implementing full-duplex communications at an access point (AP) without configuring or modifying associated stations (STAs) to operate as full duplex devices. In some implementations, the AP may select at least one of one or more first STAs to transmit uplink (UL) data to the AP, determine a downlink (DL) signal-to-interference-plus-noise ratio (SINR) for each of one or more second STAs, select at least one of the one or more second STAs to pair with the selected at least one first STA for concurrent DL and UL communications with the AP based at least in part on the determined SINRs, and transmit DL data to the selected at least one second STA concurrently with receiving at least a portion of the UL data from the selected at least one first STA.
