    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) may transmit a packet, at the beginning of a restricted TWT SP, that signals all non-member wireless stations (STAs) to defer access to the wireless medium for at least a threshold duration. Upon receiving the packet, any non-member STAs that are associated with the AP may set their network allocation vectors (NAVs) according to the duration indicated by a duration field of the received packet. In some implementations, low-latency STAs that are members of the TWT SP may not set their NAVs according to the duration field of the received packet. Instead, the low-latency STAs may access the wireless medium before the NAVs associated with the non-member STAs expire.

    Abstract: An access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field, one or more secondary change sequence fields, and a critical update flag subfield. The first change sequence field carries a value of the most-recent critical update for the first AP. The one or more secondary change sequence fields carry values of the most-recent critical updates for the one or more respective secondary APs. The critical update flag subfield carries an indication of a change in value of at least one of the secondary change sequence fields. The first AP transmits the frame over the first communication link of the AP MLD.

    Abstract: A first access point (AP) of an AP multi-link device (MLD) is associated with a first communication link, and one or more secondary APs of the AP MLD are associated with one or more respective secondary communication links of the AP MLD. The first AP of the AP MLD generates a frame including a first change sequence field and one or more secondary change sequence fields. The first change sequence field indicates a presence or absence of a critical update associated with the first communication link, and each of the one or more secondary change sequence fields indicates a presence or absence of a critical update associated with a corresponding secondary communication link of the AP MLD. The first AP of the AP MLD transmits the frame over the first communication link of the AP MLD to a station (STA) of a STA MLD.

    Abstract: This disclosure provides methods, components, devices and systems that may help various wireless devices negatively acknowledge certain wireless transmissions. An example method, performed at a first wireless node, generally includes obtaining information indicating transmission, from a second wireless node, of a physical layer (PHY) protocol data unit (PPDU) intended for the first wireless node, generating a frame indicating negative acknowledgment of at least a portion of the PPDU if one or more conditions are met, and outputting the frame to the second wireless node.

    Abstract: This disclosure provides methods, components, devices and systems for dynamic transmit power control. Some aspects more specifically relate to dynamically enable transmit power during a transmission opportunity (TxOP) to minimize the transmit power being used for message transmissions. In some implementations, a wireless device may transmit, at a first transmit power, a first message that indicates that the wireless device will transmit one or more second messages during a TxOP. The wireless device may select a second transmit power for the second message(s) and a plurality of transmission parameters, wherein the second transmit power satisfies a metric for the one or more second messages. The wireless device may transmit the second message(s) during the TxOP at the second transmit power and in accordance with respective values of the plurality of transmission parameters.

    Abstract: This disclosure provides methods, components, devices, and systems for service period parameter scheduling for frame exchange procedures. In some examples, a first wireless device (such as an access point (AP), a station (STA)), may communicate with a second wireless device (such as a STA, an AP) during a scheduled service period. The first wireless device may indicate an upper or lower limit for communication parameters used by the first wireless device and the second wireless device during the service period. The first wireless device may communicate with the second wireless device according to the limited parameters. In some examples, the first wireless device may be available to communicate with other wireless devices outside of the scheduled service period. In such examples, the first wireless device may communicate with the other wireless devices according to a second set of parameters indicated alongside the first set of parameters.

    Abstract: This disclosure provides methods, components, devices and systems for techniques for end-to-end operations between a first wireless station (STA) and a second STA via a wireless access point (AP). Some aspects more specifically relate to indicating one or more quality of service (QOS) parameters to the AP, sharing transmission opportunities (TXOPs) between the first STA and the AP, or both. In some examples, the first STA may identify one or more QoS parameters and may transmit, to the AP, an indication of the one or more QoS parameters, such that the AP may configure the second STA with the one or more QoS parameters. Additionally, or alternatively, the first STA may obtain a TXOP and may share the TXOP with the AP, such that the AP may use the shared TXOP to forward a message received from the first STA to the second STA.

    Abstract: This disclosure provides methods, components, devices and systems for discovery signaling for seamless roaming. Some aspects more specifically relate to indicating or advertising information associated with a single mobility domain (SMD) and information associated with access point (AP) devices that support seamless roaming. In some implementations, an AP device or a multi-link device (MLD) may transmit parameters associated with the SMD MLD to advertise information of the SMD MLD. In some implementations, the AP device or MLD may advertise candidate AP devices, which may support the seamless roaming. A non-MLD device, such as a wireless station (STA), may request additional information for a candidate AP device that supports seamless roaming. The AP device may transmit a response to the request indicating a portion of a profile of the candidate AP device.

    Abstract: This disclosure provides methods, components, devices and systems for enhancements to request to send (RTS) and clear to send (CTS) exchanges. A first wireless device may receive a beacon frame indicating for the first wireless device to monitor a first channel for a first frame that schedules communication via one or more channels. The first wireless device may receive, from a second wireless device, the first frame indicating a channel bandwidth and a puncturing pattern of multiple available puncturing patterns for the channel bandwidth. The puncturing pattern may be associated with a first subset of a set of multiple channels of the channel bandwidth. The first wireless device may transmit, to the second wireless device, a second frame indicating that a second subset of channels is available and may receive one or more data packets via the second subset of channels.
