Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device (e.g., station (STA), access point (AP)) may transmit to a second wireless device during a service period, an initiating frame using a transmit beam that is based on a first beam training procedure performed between the devices prior to the service period. The first wireless device may perform a second beam training procedure during the service period based on an absence of a response frame from the second wireless device, based on an indication within the response frame received from the second wireless device, or based on identification of a change in a wireless channel relative to a previous beam training interval or previous service period. The first wireless device may then communicate one or more messages with the second wireless device using one or more beams that are based on the second beam training procedure.

Abstract: This disclosure provides methods, devices and systems for transmitting and receiving, between an access point (AP) and one or more stations (STAs) in a basic service set (BSS), within a 3.5 GHz bandwidth.

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.

The method generally includes generating a protected frame that indicates: 1) an updated starting sequence number (SSN) of a block acknowledgment (BA) window and 2) an intended purpose of the protected frame as a request to update a BA window with the updated SSN; outputting, for transmission to a second wireless device that the first wireless device has established a protected block acknowledgment (BA) agreement with, the protected frame; generating multiple medium access control (MAC) Protocol Data Units (MPDUs) with SNs within the updated BA window; and outputting, for transmission to the second wireless device, the multiple MPDUs.

Abstract: This disclosure provides methods and devices for managing the allocation of resources for uplink (UL) and downlink (DL) transmissions associated with a scheduled time period. In some implementations, a wireless station (STA) transmits, to an access point (AP), a request frame indicating a bandwidth or a quantity of spatial streams (or both) for the UL transmissions, and indicating a bandwidth or a quantity of spatial streams (or both) for the DL transmissions. In some instances, the request frame also may indicate the STA's intention to transmit UL data as duplicates carried on different communication links. The STA receives a trigger frame indicating that the STA is scheduled to transmit or receive data during the time period. The STA transmits data to, or receives data from, one or more other devices during the time period.

A first wireless device may receive a first signaling indicating a first reservation of a first transmission opportunity (TXOP) for a second wireless device on a first primary channel. The first wireless device may obtain a second TXOP to transmit or receive, via a second primary channel, a second signaling indicating a second reservation of the second TXOP. The ending time of the second TXOP may occur prior to an ending time of the first reservation and prior to a transition delay associated with a communication event scheduled on the first subset of channels or a second subset of channels.

Abstract: This disclosure provides methods, components, devices and systems for enabling coordinated multiple access on multiple primary channels. Some aspects more specifically relate to inter access point (AP) coordination to share a portion of a transmission opportunity (TXOP). A first AP may transmit a first signal on a secondary primary channel conveying an indication that a portion of the TXOP is available for sharing. The second AP may respond with a confirmation on the secondary primary channel that the second AP is tuned to the secondary primary channel. Accordingly, the second AP may transmit a second signal on the secondary primary channel to the first AP indicating that the portion of the TXOP is available for use. The second AP may use the portion of the TXOP to communicate with one or more station(s) on the secondary primary channel.

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 multi-hop support for coordinated medium access. Some aspects more specifically relate to one or more mechanisms according to which an access point (AP) may indicate how many hops a medium access schedule is to be re-announced throughout a wireless network. In some examples, a first AP may select a medium access schedule and may transmit timing information indicative of communication periods associated with the medium access schedule and a value associated with a multi-hop propagation of the timing information. A second AP may receive the timing information and the value and may selectively transmit the timing information in accordance with the value. For example, if the value is indicative of greater than or equal to a threshold hop count value, the second AP may propagate the timing information associated with the communication periods of the first AP.

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 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 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 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.

Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications during restricted target wake time (r-TWT) service periods (SPs). Some implementations more specifically relate to coordinated scheduling of r-TWT SPs between OBSSs. In some aspects, a first AP may coordinate with a second AP in scheduling r-TWT SPs so that latency-sensitive traffic in a first BSS does not interfere or collide with latency-sensitive traffic in a second BSS overlapping the first BSS. In some implementations, the first and second APs may schedule their respective r-TWT SPs to be orthogonal in time. In some other implementations, the first and second APs may schedule their r-TWT SPs to overlap in time, while allocating coordinated resources to concurrent or overlapping latency-sensitive traffic in the first and second BSSs (such as in accordance with one or more multi-AP coordination techniques).
