Abstract: A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.

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.

Abstract: This disclosure provides methods, components, devices and systems for flexible control frames. Some aspects more specifically relate to indicating control information or control feedback in control frames including fields of flexible size. In some implementations, a wireless device may include control feedback in a dedicated feedback field within responsive control frames, within initial control frames, or both. The wireless device may indicate that a field includes the control feedback using bit sequences in one or more other subfields, such as a traffic identifier (TID) subfield or user information subfield. In some implementations, the control feedback information may provide another wireless device with additional information associated with a transmission, such as information associated with an upcoming data transmission or a reception status of a communicated data transmission.

Abstract: This disclosure provides methods, components, devices and systems for multi-primary channel access operation. Some aspects more specifically relate to improving the efficiency of multi-primary channel access schemes. In some implementations, the first wireless device may use multiple primary subchannels. 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 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 a method for wireless communication performable at an access point (AP). The AP transmits a first frame to a non-AP wireless station (STA). A first field of the first frame indicates transmission information associated with one or more second frames. A second field of the first frame contains a first set of parameters associated with the AP. The AP further transmits a second frame to the non-AP wireless STA. The second frame may include at least one field containing a second set of parameters associated with the AP. The first set of parameters are different from the second set of parameters.

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 for signaling mechanisms for low latency and low complexity relay designs. Some aspects more specifically relate to an end-to-end (E2E) relay framework according to which a satellite access point (AP) may relay one or more protocol data units (PDUs) and a block acknowledgment (BA) associated with the one or more PDUs between a client device and a root AP within a single transmission opportunity (TXOP). In some implementations, the satellite AP may refrain from performing operations associated with reordering and retransmitting as part of the relay. In some other implementations, the satellite AP may perform some amount of retransmissions in accordance with a time duration of the TXOP. The root AP, the satellite AP, and the client device may support an end-to-end encryption of both the set of PDUs and the BA associated with the set of PDUs.

Abstract: This disclosure provides methods, components, devices and systems for techniques for coordinated medium access for ultra-high reliability. Some aspects more specifically relate to access point (AP)-to-AP coordination via, for example, one or more management frames. In some implementations, a wireless communication device may coordinate timing information with one or more other APs and may inform a set of stations (STAs) of the coordinated timing information, where a configured set of identifiers (IDs) may be used to differentiate which timing information pertains to which AP and inform how the set of STAs are expected to parse the coordinated timing information. Additionally, or alternatively, wireless communication devices may exchange one or more public action frames to facilitate AP-to-AP coordination, where such one or more public action frames may be specifically associated with providing information pertaining to coordinated medium access. Further, the described techniques may be applicable to multi-hop relay topologies.

Abstract: This disclosure provides methods, devices and systems for enhanced bandwidth negotiation. Some implementations more specifically relate to request-to-transmit (RTS) and clear-to-send (CTS) frame designs that support bandwidth negotiations over a range of bandwidths achievable in accordance with the IEEE 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, a bandwidth negotiation frame (such as a CTS or RTS frame) may be configurable to support bandwidths greater than 160 MHz. In some aspects, the bandwidth negotiation frame may conform to a legacy control frame format. More specifically, one or more bits of a service field associated with the legacy control frame format may be repurposed to carry enhanced bandwidth information. In some aspects, a recipient of a bandwidth negotiation frame may interpret one or more bits of the service field to carry enhanced bandwidth information when the frame is transmitted by a non-legacy transmitting device.
