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: Certain aspects of the present disclosure relate to wireless communications. According to certain aspects, a method that may be performed by an access point (AP) includes outputting, for transmission to an access point (AP), a request to associate with the AP, wherein the request is encrypted with a first set of one or more keys; obtaining, from the AP, a response to the request; decrypting the response, based on the first set of keys, to obtain a second set of one or more keys; and using the second set of keys for secure data exchange with the AP.

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: 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: Uplink reporting and logical channel prioritization in multiflow operation is described. In some embodiments, uplink reporting for multiflow operation utilizes bearer level splitting where the UE associates bearers or logical channel groups (LCGs) with cells for uplink reporting. In some embodiments, uplink reporting for multiflow operation utilizes packet level splitting where the UE groups buffers for all LCGs into a common pool for uplink reporting. In packet level splitting embodiments, the UE may perform uplink reporting based on the total amount of data available for transmission in the common buffer pool or by applying scaling coefficients associated with the serving cells. Some embodiments manage mapping of logical channel payloads to uplink grants for multiflow operation.

Abstract: This disclosure provides methods, components, devices and systems for addressing client constraints in dynamic subchannel operation (DSO). Some aspects more specifically relate to a DSO frame exchange between an access point (AP) multi-link device (MLD) and a non-AP MLD that is operating in accordance with an enhanced multi-link single-radio (EMLSR) or an enhanced multi-link multi-radio (EMLMR) communication mode. In such aspects, the non-AP MLD may use a frame associated with a DSO frame exchange to trigger the non-AP MLD to perform an operation associated with the EMLSR/EMLMR communication mode. Some additional, or alternative, aspects more specifically relate to a DSO frame exchange between an AP MLD and a non-AP MLD that has disabled a communication mode associated with uplink multi-user (MU) communication. In such aspects, the AP MLD and the non-AP MLD may apply one or more constraints on the DSO frame exchange associated with the disabled uplink MU communication.

Abstract: This disclosure provides methods, components, devices and systems for quality of service (QOS) based peer-to-peer (P2P) transmission opportunity grants. A first wireless communication device receives a first management message including a first stream identifier associated with a second wireless communication device. The first wireless communication device transmits a second management message to an access point, the second management message including a second stream identifier and an identifier of the second wireless communication device based on the first management message. The first wireless communication device receives a first control message associated with a shared transmission opportunity, the first control message including parameters that satisfy a set of QoS of the second wireless communication device, where the first control message enables the shared transmission opportunity for the second wireless communication device and a third wireless communication device.

Abstract: This disclosure provides methods, components, devices and systems for service period based coordinated spatial reuse. Some aspects relate to long term signaling to reduce the amount of signaling while achieving the gain associated with coordinated spatial reuse as compared to distributed spatial reuse. A first wireless device associated with a first basic service set (BSS) may transmit a beacon indicating a set of service periods designated for spatial reuse and an interference threshold. A second wireless device associated with a second BSS may receive the beacon and may communicate with one or more other wireless devices associated with the second BSS during the set of service periods designated for spatial reuse in accordance with the indicated interference threshold. Accordingly, the wireless devices in the second BSS may communicate at a power level that causes an acceptable level of interference at the first BSS.

Abstract: This disclosure provides methods, components, devices and systems for negotiation for coordinated medium access between wireless devices. Some aspects more specifically relate to techniques for negotiation between wireless devices for medium access. In some examples, wireless devices may transmit requests and responses to negotiate for conflicting medium access periods between wireless devices, where the wireless devices may be in different basic service sets (BSSs). For example, wireless devices such as wireless access points (APs) may broadcast a reservation of medium access periods. In some examples, a first wireless device may transmit a request to negotiate medium access periods with a second wireless device, and the second wireless device may transmit a response to the request. For example, the request to negotiate may request that the wireless devices mutually honor or respect (for example, comply with) one or more of the medium access period reservations of each wireless device.

Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.
