Abstract: This disclosure provides methods, components, devices, and systems for reconfiguration signaling for seamless roaming. Some aspects more specifically relate to reconfiguration signaling to facilitate link addition and link deletion operations for roaming, such as seamless roaming. Either a wireless station (STA) or an access point (AP) device may initiate the roaming. In some examples, a first device, such as the STA, a serving AP device, or a target AP device, may transmit a reconfiguration request to a second device, requesting to perform a link addition operation on links of the target AP device or to perform a link deletion operation on links of the serving AP device. The second device, which may be the STA, the serving AP device, or the target AP device, may transmit a reconfiguration response to indicate which links are to be deleted or added.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for coordinated scheduling of service periods (SPs). In some aspects, an access point (AP) may receive timing information indicating an SP associated with an overlapping basic service set (OBSS) and may transmit, to its associated STAs, coordinated timing information indicating the timing of the SP in relation to its timing synchronization function (TSF) timer. In some aspects, the AP may adjust the timing information to account for an offset between its TSF timer and a TSF timer associated with the OBSS. In some other aspects, the AP may synchronize its TSF timer with the TSF timer associated with the OBSS. The AP may further communicate with the STAs based on the coordinated timing information. For example, the AP may schedule communications with the STAs to be orthogonal to communications in the OBSS during the SP.

Abstract: This disclosure provides methods, components, devices and systems for frame protection in wireless communications. Some aspects more specifically relate to a first wireless device (such as a STA or AP) that may transmit frames with a packet number (PN) that has a time-based portion and a counter value. In some examples, the time-based portion may include a truncated timing synchronization function (TSF) value that indicates a time at which the frame was transmitted from the first wireless device, and the counter value may be incremented for each frame that is transmitted with a same truncated TSF value. A second wireless device may receive the frame and compare the truncated TSF with a current local time based on a truncated local TSF. The second wireless device may process the frame or discard the frame based on the comparison.

Abstract: This disclosure provides methods, components, devices and systems for low latency channel access. Some aspects more specifically relate to preemption of existing transmission opportunities (TXOPs) such that devices with low latency traffic to transmit may access the communication medium to transmit low latency traffic. Short physical layer protocol data units (PPDUs) may be used within TXOPs with interframe spaces between the PPDUs such that a device with low latency traffic may transmit a preemption indication during the interframe space. A first wireless communication device may identify low latency traffic during a first PPDU of a TXOP assigned to a second wireless communication device. The first wireless communication device may transmit a preemption indication in an interframe space that indicates that a subsequent scheduled PPDU in the TXOP will be preempted in order for the first wireless communication device to transmit a PPDU to convey the low latency traffic.

Abstract: This disclosure provides methods, components, devices and systems for coordinated medium access period management for overlapping basic service sets (OBSSs). Some aspects more specifically relate to coordinated medium access between access points (APs) and stations (STAs) of an OBSS. In some examples, a first STA may monitor, over one or more medium access periods, for communications between a neighbor AP and one or more second STAs. The one or more medium access periods may be configured for medium access and resource reservation for communications between the neighbor AP and the one or more second STAs. In some examples, the first STA may transmit to an associated AP, a report indicating the one or more attributes associated with the monitoring over the one or more medium access periods. In some examples, the report may be solicited or unsolicited, and the STA may monitor for communications over one or more measurement windows.

Abstract: This disclosure provides methods, components, devices, and systems that support information exchanges for coordinated access point (CAP) operations. Some aspects more specifically relate to transmitting and receiving CAP-specific parameters to facilitate transmit opportunity (TXOP) sharing between a first access point (AP) and one or more second APs. For example, the first AP (such as a sharing AP) may use CAP-specific parameters provided by the one or more second APs (such as shared APs) to determine a CAP sharing schedule for a TXOP. The CAP-specific parameters may include static capability parameters and dynamic parameters. The static capability parameters may include supported CAP modes, association identifiers (AIDs), and processing times, while the dynamic parameters may include medium access demands, traffic priority information, and service period information. The first AP may advertise the CAP sharing schedule to the one or more second APs via an announcement frame.

Abstract: This disclosure provides methods, components, devices, and systems for enhanced downlink (DL) data delivery. Some aspects more specifically relate to reducing the latency and power consumption associated with delivering DL buffered units (BUs) to stations (STAs) in an enhanced delivery mode. In some implementations, an access point (AP) may transmit an indication of queue information associated with one or more pending DL BUs for a STA. The AP may identify a set of operational parameters to use for transmission of the one or more pending DL BUs in accordance with the queue information. Likewise, the STA may identify a set of operational parameters to use for reception of the one or more pending DL BUs in accordance with the queue information. The AP may transmit the one or more pending DL BUs to the STA in accordance with the queue information and the set of operational parameters.

Abstract: This disclosure provides systems, methods, and apparatus for wireless communications. In one aspect, an apparatus may obtain, for a first access point (AP), a first service set identifier (SSID) associated with single-link communications and obtain, for a second AP, a second SSID associated with multi-link communications. The apparatus may obtain, from a wireless communication device, a management frame include a multi-link operation information field that carries a first SSID and obtain a multi-link indication for the wireless communication device based, at least in part, on the first SSID, the multi-link indication indicating whether the wireless communication device includes AP capable of link aggregation, and selectively associate with the wireless communication device based on the multi-link indication.

Abstract: This disclosure provides methods, components, devices and systems for machine learning models for spatial reuse. Some aspects more specifically relate to machine learning (ML) models for spatial reuse (SR). In some aspects, an access point (AP) may transmit ML model information to a station (STA). The ML model information may include an indication of an ML model, one or more parameters defining the ML model, one or more inputs for the ML model, one or more outputs for the ML model, or any combination thereof. A transmitting device may generate one or more inputs for the ML model, which may be local measurements or observations, input values indicated by one or more other STAs, information provided by an AP, one or more inferences (such as a candidate SR parameter value, or candidate action), or a combination thereof.

Abstract: This disclosure provides methods, components, devices and systems for performing actions to reduce end-to-end latency during a transmission of an encrypted payload of a medium access control (MAC) protocol data unit (MPDU) from a root access point (AP) to a wireless station (STA) via a satellite AP. For example, the satellite AP may be configured to receive the encrypted payload from the root AP, and then forward the received encrypted payload to the wireless STA, without decrypting the received encrypted payload and re-encrypting unencrypted payload at the satellite AP.
