    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to establish a restricted target wake time (TWT) session on a wireless medium. In some implementations, an access point (AP) establishes a restricted TWT session for one or more wireless stations (STAs) associated with latency sensitive traffic, the restricted TWT session including restricted TWT service periods (SPs) during which the AP reserves access to the wireless medium for only the one or more STAs associated with the latency sensitive traffic. The AP transmits a clear-to-send (CTS) frame at a start of each restricted TWT SP, the CTS frame indicating to other STAs that the wireless medium is unavailable for a duration of the respective restricted TWT SP. The AP transmits latency sensitive data to or receives latency sensitive data from the one or more STAs during at least one of the restricted TWT SPs.

    Abstract: This disclosure provides methods, devices and systems for reliable delivery of enhanced broadcast services (EBCS) downlink (DL) packets to wireless stations (STAs) that support EBCS (also referred to as “EBCS STAs”) and maintaining interoperability with STAs that do not support EBCS. A wireless communication device may broadcast one or more EBCS DL packets carrying data associated with an EBCS service. In some aspects, the wireless communication device may subsequently transmit a trigger frame soliciting information indicating which, if any, of the EBCS DL packets were missed by EBCS STAs in the vicinity. In some other aspects, each EBCS DL packet may carry signaling indicating that the broadcast data is intended only for EBCS STAs. Still further, in some aspects, the wireless communication device may broadcast an EBCS traffic advertisement indicating a timing of the one or more EBCS DL packets.

    Abstract: This disclosure provides systems, methods and apparatuses for advertising discovery information of an AP in one or more downlink (DL) transmissions. In some implementations, the AP may allocate a dedicated resource unit (RU) for advertising discovery information of the AP to stations not associated with the AP, and may allocate one or more additional RUs for DL transmissions to one or more stations associated with the AP. The AP may transmit a multi-user (MU) packet containing discovery information intended for the unassociated stations and containing non-discovery-related information intended for the one or more associated stations. The discovery information may be transmitted on the dedicated RU, and the non-discovery-related information may be transmitted on the one or more additional RUs.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multi-link aggregation in wireless communications. In one aspect, an apparatus includes a multi-link operation device configured to generate and output for transmission a message indicating a mapping of each of a plurality of traffic identifiers (TIDs) to one or more parameters associated with each of a plurality of wireless links. In some aspects, another apparatus may obtain a message via at least one of a plurality of wireless links indicating a mapping of each of a plurality of TIDs to one or more parameters associated with each the plurality of wireless links, obtain a sequence of packets associated with at least one of the plurality of TIDs via one or more of the plurality of wireless links, and process the sequence of packets based on the mapping indicated via the message.

    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support a 20 MHz station (STA) parked on a secondary channel. Without the described techniques, mechanisms to support secondary channel operation may be unable to receive management frames or broadcast traffic from an access point (AP), which may cause the STA to lose synchronization with the AP, miss a channel change or other critical announcement from the AP, etc. Considerations for providing such information to STAs parked on a secondary channel are discussed. In some examples, an AP may restrict resource unit allocation to the secondary channel on which the STA is parked. In some cases, a trigger-based random access mechanism may utilize aspects of the present disclosure to limit access to certain resource units to STAs on a given secondary channel.

    Abstract: Methods, systems, and devices for wireless communications are described. A first wireless communication device may determine a first set of parameters for communicating with a second wireless communication device within a first set of time intervals, the first set of parameters associated with a beamforming procedure. The first wireless communication device may predict, based on inputting the first set of parameters to a machine learning model, a second set of parameters corresponding to a second set of time intervals in the future after the first set of time intervals. The first wireless communication device may select a beamforming configuration for communications between the first wireless communication device and the second wireless communication device based on the second set of parameters, and may communicate with the second wireless communication device within the second set of time intervals in accordance with the beamforming configuration.

    Abstract: This disclosure provides methods and devices for introducing a power save protocol (for example, a lower power mode) for a multi-link devices (MLDs). Some aspects more specifically relate to reducing power consumption in an access point (AP) MLD, and more particularly, to a power save protocol (or a lower power mode) for an AP MLD. In some aspects, an AP MLD may initiate a lower power mode to save power for as long as possible while still maintaining minimal receive (RX) and transmit (TX) functionality. When requested by an associated station (STA), the AP MLD may then transition from the lower power mode to a higher power mode with full RX and TX functionality with a minimal delay. The described techniques may also account for trade-offs and constraints which arise due to different use cases and scenarios as well as different device configurations.

    Abstract: This disclosure provides methods, components, devices and systems for use of a reinforcement learning (RL) model to obtain one or more parameters associated with a channel access procedure. Some aspects more specifically relate to mechanisms according to which a wireless communication device may receive information associated with the RL model and transmit a protocol data unit (PDU) during a slot that is based on an output of the model. The wireless communication device may use the RL model to perform a distributed channel access procedure in accordance with the information and may further transmit the PDU, during the slot that is based on the output of the RL model, in accordance with the distributed channel access procedure. The information associated with the RL model may indicate or configure the RL model or may indicate whether the wireless communication is allowed to retrain the RL model.
