Abstract: This disclosure provides methods, components, devices and systems for back-to-back transmissions via a multi-hop relay path using flow-specific resource reservation. Some aspects more specifically relate to flow-specific transmission opportunity (TXOP) sharing and/or orthogonal channel reservation in combination with a flow-specific sequence of time slots. In implementations in which flow-specific TXOP sharing is employed in combination with a flow-specific sequence of time slots, one or more wireless communication devices may determine whether a shared TXOP supersedes the flow-specific sequence of time slots in accordance with whether the shared TXOP is associated with a same flow as the sequence of time slots. In implementations in which orthogonal channel reservation is employed in combination with a flow-specific sequence of time slots, each wireless communication device of a multi-hop relay path may receive an indication of or otherwise be configured with a frequency channel via which to transmit.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication at a wireless node, generally including communicating, via a first link, with a first access point (AP) device affiliated with a single mobility domain (SMD) entity, outputting, for transmission to the first AP device, a first message including a first indication that the wireless node is initiating a handover of the wireless node from the first AP device to a second AP device affiliated with the SMD entity, communicating with the second AP device via a second link during the handover after obtaining a second indication that context information has been transferred from the first AP device to the second AP device, and disabling the first link with the first AP device after obtaining a third indication that triggers the wireless node to disable the first link with the first AP device.

Abstract: A first Multi-AP device configured as a Multi-AP Agent transmits, to a second Multi-AP device configured as a Multi-AP Controller over a first communication link, a Device Provisioning Protocol (DPP) Configuration Request Message indicating multi-link operation (MLO) capabilities of the first Multi-AP device. The first Multi-AP device receives, from the second Multi-AP device over the first communication link, a DPP Configuration Response Message indicating MLO association information responsive to the indicated MLO capabilities, and establishes a backhaul path with a third Multi-AP device, configured as a second Multi-AP Agent, on the first communication link and one or more second communication links according to the MLO association information. The MLO capabilities may be indicated in a DPP Configuration Object of the DPP Configuration Request Message, and the MLO association information may be indicated in a multi-link device (MLD) address field of a DPP Configuration Object of the DPP Configuration Response Message.

Abstract: This disclosure provides methods, devices and systems for reducing power consumption in neighbor awareness networking (NAN) devices. Some implementations more specifically relate to dynamically adjusting a NAN device link (NDL) schedule to reduce the idle duration of a NAN data interface (NDI). The NDL schedule identifies a number of NAN slots, per discovery window (DW) interval, during which an NDL is available for data communications between NAN devices. In some aspects, a NAN device may measure congestion on the wireless channel during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured congestion. In some other aspects, a NAN device may measure throughput on the NDL during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured throughput.

Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a first signal including an indication of a set of frequency channels for a set of target wake time (TWT) sessions that recur according to a service interval. In some examples, the first signal may indicate a respective frequency channel of the set of frequency channels for each TWT session of the set of target wake time sessions. Each TWT session of the set of TWT sessions may have an associated service period that the STA may be in an awake state. The STA may switch, for the first TWT session, from the first frequency channel to the second frequency channel. In some examples, based on the switching, the STA may communicate a signal during a service period associated with the first TWT session over the second frequency channel.

Abstract: This disclosure provides methods, devices and systems for performing a single-sided ranging operation. In some implementations, a first device transmits a first frame to a wireless station (STA), and receives a second frame from the STA responsive to the first frame. The first device obtains information indicating a time period between transmission of the first frame and reception of the second frame by the first device, and obtains information indicating time delays associated with a plurality of second devices, where each of the time delays is between respective receptions of the first frame and the second frame by a respective one of the second devices. The first device obtains a position of the STA based on the time period, the time delays associated with the plurality of second devices, and signal propagation times between the first device and each of the plurality of second devices.

Abstract: This disclosure provides methods, devices and systems for reducing beacon bloat, inefficient spectrum use, and coupling of multi-link transmission element (MLTE) with a traffic indication map (TIM) element. In certain aspects, an MLTE may be transmitted by an access point (AP) multi-link device (MLD) in a frame separate from the beacon frame to reduce the size of the beacon frame. In such an example, the beacon frame may provide an indication to a non-AP MLD that is should remain awake to receive data. In certain aspects, the AP may transmit multiple MLTEs to reduce the amount of bandwidth used for MLTE transmission by cutting out non-AP MLDs and other stations (STAs) that do not have buffered data. In certain aspects, the AP may assign each non-AP MLD capable of transmission identifier (TID)-to-link mapping (TID2LM) with a per-link traffic indication bitmap (PLTIB) to decouple the MLTE from the TIM element.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a device participating in a setup procedure to efficiently propose a range of values for a negotiated parameter. The techniques may reduce setup time, for example, allowing a responder to accept a value within the proposed range which may eliminate overhead associated with some of the back and forth message exchange of typical negotiations.

Abstract: The present disclosure provides techniques for rate adaptation under congestion and latency constraints. The approaches described herein focus on aspects of latency, reliability, and power consumption instead of the traditional aspect of throughput. In an example, a method for rate adaptation is disclosed. The method may include determining whether to transmit a new packet or a retry packet. The method may also include reducing a maximum rate for a rate search in response to determining to transmit the retry packet. The method may further include transmitting the retry packet based on the reduced maximum rate.
