Abstract: Techniques for improved peer-to-peer communication are provided. A wireless access point (AP) may initiate peer-to-peer communication between multilink peer-to-peer devices by sending a trigger frame addressed to the peer-to-peer devices to hand over a transmission opportunity (TXOP). The trigger frame is sent based on the AP's knowledge of the availability of the peer-to-peer devices for peer-to-peer communication. The trigger frame indicates a link to be used for the peer-to-peer communication. In response to receiving the trigger frame one or more of the peer-to-peer devices acknowledge the trigger frame, tune to the assigned link, and use the remaining portion of the TXOP for peer-to-peer communication.

Abstract: An AP may want to change the non-primary channel access (NPCA) primary channel (NPCH) when the primary channel for the BSS is unavailable, e.g., due to interference on the current NPCH or as a result of RRM. The embodiments herein describe techniques to coordinate the NPCH change and announce it in advance so that both the access point (AP) and stations (STAs) start using the new NPCH at the same time. That is, the embodiments herein describe mechanisms where both the AP and associated STAs start using the new NPCH at the same time when the NPCH changes.

Abstract: A signaling mechanism is provided that includes a restricted random access resource unit (XRA RU) that restricts uplink random access, such as by using Uplink Orthogonal frequency-division multiple access-based Random Access (UORA), to a subset of a plurality of stations that are associated with an Access Point (AP). In one aspect, an AP allocates a resource unit as an XRA RU that restricts uplink random access to a subset of a plurality of stations (STAs) that are associated with the AP. The AP transmits an uplink trigger that includes the XRA RU. The AP restricts use of the XRA RU to the subset of the plurality of STAs. In this way, STAs of the subset can attempt contention-based random access with the XRA RU while other STAs are prevented from attempting random access with the XRA RU.

Abstract: Techniques for intelligent multi-link operation (MLO) mode selection are provided. One or more metrics for wireless communication in a wireless network is collected. A set of multi-link operation (MLO) modes available for the wireless communication between a station multi-link device (STA MLD) and a first access point multi-link device (AP MLD) in the wireless network is determined. A first MLO mode of the set of MLO modes is selected based on the one or more collected metrics. The wireless communication is performed using the selected first MLO mode.

Abstract: Detection of rogue access points (APs) through an AP that is associated with a mobility domain in a network. Unvalidated APs that attempt to join the network may be validated by another AP that is associated with the network. The unvalidated and associated APs may exchange signatures to determine if the unvalidated AP knows a key associated with the network. If the unvalidated AP does not know the key, the unvalidated AP is not validated for the network. The AP that was doing the validation may transmit a message to devices on the network indicating a rogue AP, the unvalidated AP, is attempting to join the network.

Abstract: The present disclosure provides techniques for mitigating Man-in-the-Middle (MITM) and replay attack within a mobility domain. An access point (AP) within a seamless mobility domain (SMD), generates a frame comprising an SMD signature, an SMD identifier, and a replay protection value, where the SMD signature is generated by signing a data structure comprising the SMD identifier and the replay protection value using a private key associated with the SMD. The AP transmits the frame to a station (STA) for verification.

Abstract: Combining MBSSID sets, co-hosted BSSID sets, and standalone VAPs into a co-located, co-channel BSSID set to allow for more efficient communication between different members of the co-located, co-channel BSSID set. By combining the members into the co-located, co-channel BSSID set, when a TXOP holder provides transmission time to a co-located, co-channel BSSID set, each of the VAPs in the co-located, co-channel BSSID set receives access to exchange data for a duration of time. When the co-located, co-channel BSSID set indicates to the TXOP holder that the VAPs finished exchanging data, each of the VAPs in the co-located, co-channel BSSID set loses access to send data.

Abstract: Irregular unavailability signaling may be provided. An Access Point (AP) may receive an irregular unavailability report from a station. The irregular unavailability report may include a priority associated with upcoming unavailability periods of the station for non-Peer-to-Peer (P2P) traffic and an indication of interruptibility of the P2P traffic in the upcoming unavailability periods. The AP may schedule Transmit Opportunities (TxOPs) of the non-P2P traffic to the station in the upcoming unavailability periods based on the priority associated with upcoming unavailability periods and the indication of interruptibility of the P2P traffic.

Abstract: Embodiments for enabling a non-access point (non-AP) multi-link device (MLD) to transfer one or more existing Target Wake Time (TWT) agreements to a new link either for an AP MLD or across AP MLDs. In at least one embodiment, a computer-implemented method is provided that includes obtaining, from a non-AP MLD that is seeking to roam from a first AP MLD to a second AP MLD, a request to transfer one or more TWT agreements from one or more wireless links of the first AP MLD to one or more wireless links of the second AP MLD; determining whether any of the one or more TWT agreements are accepted for any wireless links of the second AP MLD; and providing a response to the non-AP MLD indicating whether any of the TWT agreements are accepted for the wireless links of the second AP MLD.

The SCS request comprises information for a plurality of quality of service (QoS) profiles associated with the SCS identifier, and each of the plurality of QoS profiles define a different set of QoS characteristics.

Abstract: Signal mechanisms are described for performing dynamic bandwidth expansion (DBE) at an access point (AP). In one embodiment, the AP and stations (STAs) exchange signals indicating their respective DBE capabilities (e.g., whether DBE is supported, maximum dynamic BW, etc.). Later, the AP (or a network controller) can determine to perform DBE. For example, the load on the AP may jump because the AP is located in a conference room or an event center. To provide additional BW, the AP (or RRM) can determine to perform DBE to increase the bandwidth available to the AP. To do so, the AP transmits a DBE announcement to inform the STAs. This announcement can include information such as bandwidth, center frequency, whether a subchannel is punctured, etc.). The AP and STAs can then use the expanded bandwidth.

The embodiments herein describe techniques to coordinate the NPCH change and announce it in advance so that both the access point (AP) and stations (STAs) start using the new NPCH at the same time. That is, the embodiments herein describe mechanisms where both the AP and associated STAs start using the new NPCH at the same time when the NPCH changes.

Abstract: Access Point (AP) coordination and, specifically, Multi-AP Coordination (MAPC) for Non-Simultaneous Transmit and Receive (NSTR) cross-band Physical Layer Protocol Data Unit (PPDU) alignment may be provided. The coordination can include determining to communicate with a client using MAPC Multi-Link-Device (MLD) operation. A first AP operating on a first band with a first link to the client and a second AP operating on second band with a second link to the client may be determined to communicate with the client. The first AP and the second AP may be coordinated to send one or more PPDUs with synchronized end times. The first AP may be instructed to transmit to the client via the first link and the second AP may be instructed to transmit to the client via the second link according to the coordination.

Abstract: The present disclosure provides techniques for classification and advertisement of MBBR capabilities in wireless networks. An AP broadcasts an advertisement that indicates one or more supported roaming modes, each roaming mode being associated with a respective RQL. The AP receives from a STA a request that includes a first roaming mode selected by the STA and one or more roaming capability parameters associated with the STA. In response to determining that the AP is capable of supporting the first roaming mode for the STA, the AP transmits to the STA a response indicating confirmation of the first roaming mode.

Abstract: Wireless stations (STAs) are described that announce dynamic bandwidth expansion (DBE) parameters to an access point (AP). This can occur before, or after, the AP announces the start of a DBE session. For example, the STAs can inform the AP of the particular expanded bandwidths (E-BWs) they can support (e.g., 80, 160, or 320 MHz). Using this information, the AP can determine the E-BW to announce for the DBE session. Moreover, the STA can experience conditions where it wants to change the maximum E-BW it can support, or to disable DBE, in order to, e.g., conserve power. The STA can transmit to the AP an updated message that includes changed DBE parameters.

Abstract: An access point (AP) can account for Non-Primary Channel Access (NPCA) operation during Dynamic BW Expansion (DBE) where a BW of a BSS is expanded or reduced. When BSS BW is dynamically expanded using DBE, the embodiments herein provide signaling and behaviors performed by the AP such that NPCA can operate over the expanded BW. In one embodiment, the AP updates an NPCA primary channel (NPCH) used during NPCA when changing the BW of a BSS/AP during DBE. For example, NPCA may already be enabled in the BSS in which case the AP moves the NPCH to a new channel that is within the expanded BW. In another embodiment, NPCA is not enabled in the BSS before the BW is expanded in which case the AP enables NPCA during the BDE session.

Abstract: A method performed by an access point comprises: transmitting, to a station, an enhanced trigger frame to trigger the station to transmit traffic, wherein the enhanced trigger frame includes: a user information field having an association identifier (AID) field encoded with an AID of the station, and a finer granularity triggering field indicating finer granularity triggering based on a preferred traffic category identifier, a preferred traffic identifier, a preferred traffic stream identifier, or a preferred stream classification service identifier; and a parameter field encoded with particular parameters for the preferred traffic category identifier, the preferred traffic identifier, the preferred traffic stream identifier, or the preferred stream classification service identifier to which the station is to respond with the traffic mapped to the particular parameters.

Abstract: Methods for mapping Stream Classification Service (SCS) flows to Traffic Identifiers (TIDs)/Traffic Stream Identifiers (TSIDs) based on User Priority (UP) and quality of service (QoS) characteristics of SCS flows such that two SCS flows with the same UP but different QoS characteristics map to different TIDs/TSIDs to avoid head of line blocking. Methods involve obtaining, by a first wireless device, a first stream classification service (SCS) traffic flow and determining a user priority value and quality of service (QoS) characteristics of the first SCS traffic flow. The methods further involve mapping the first SCS traffic flow to a traffic identifier selected from a plurality of traffic identifiers based on a combination of the user priority value and the QoS characteristics and processing the first SCS traffic flow based on the traffic identifier for transmission to a second wireless device or when received from the second wireless device.
