Abstract: Aspects presented herein may improve the efficiency and accuracy of ranging operations, such as ranging operations based on ultra-wideband or sidelink. In one aspect, a first wireless device receives a response message from at least one second wireless device, the response message including a clock accuracy value of the at least one second wireless device, a location confidence value of the at least one second wireless device, or a combination thereof. The first wireless device establishes a ranging session with the at least one second wireless device based on the clock accuracy value of the at least one second wireless device exceeding a clock accuracy threshold, or the location confidence value of the at least one second wireless device exceeding a location confidence threshold, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may perform a listen-before-talk (LBT) procedure for a narrowband communication that provides time and frequency synchronization and/or scheduling information for an ultra-wideband (UWB) communication. The wireless device may transmit the narrowband communication in response to the LBT procedure being successful. The wireless device may transmit the UWB communication based at least in part on the time and frequency synchronization and/or scheduling information. Numerous other aspects are described.

Abstract: In some implementations, a current synchronization reference anchor for the group of RF positioning anchors may obtain metric information from each radio frequency (RF) positioning anchor of the group of RF positioning anchors. The current synchronization reference anchor may select the new synchronization reference anchor from the group of RF positioning anchors based at least in part on the metric information.

Abstract: An example signal transfer method includes: determining, at a first apparatus, whether to transmit an ultra-wideband physical-layer signal with a first configuration or a second configuration based on an application for transfer of the ultra-wideband physical-layer signal, the first configuration being different from the second configuration; and transmitting, from the first apparatus to a second apparatus, the ultra-wideband physical-layer signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an initiating device may transmit a signal that includes multiple packets. The initiating device may receive, from a responding device, a channel impulse response (CIR) report for each packet of the multiple packets. The initiating device may align, using one or more taps in the CIR report for each packet, the CIR reports across the multiple packets to identify a target object, a location of the target object, or a movement of the target object. The initiating device may perform an action based at least in part on the target object, the location of the target object, or the movement of the target object. Numerous other aspects are described.

Abstract: This disclosure provides methods, components, devices and systems for radio frequency sensing control for an ultra-wideband system. Some aspects more specifically relate to setting up one or more sensing instances (sensing rounds) for one or more respective sensing operations. In some implementations, a first wireless device (for example a controller, an initiator) may transmit a sensing session setup request frame that indicates a set of parameters for the one or more sensing instances. For each of the sensing instances, the first wireless device may transmit a sensing control information element that includes at least a common sensing control configuration and a channel impulse response report configuration. The first wireless device may participate in the sensing operations with at least a second wireless device (for example one or more responders or controlees) during the respective sensing instances.

Abstract: In some implementations, a first ultra-wideband (UWB) device may determine a respective time offset for each scrambled timestamp sequence (STS) in a series of STS used for ranging in a UWB ranging session between the first UWB device and the second UWB device, wherein the respective time offset for each STS in the series of STS is determined in accordance with time offset information shared between the first UWB device and the second UWB device. The first UWB device may transmit the series of STS via UWB radio frequency (RF) signals during the UWB ranging session, wherein each STS in the series of STS is transmitted with the respective time offset.

Abstract: In some implementations, a transmitting UWB device may determine a number of information bits of a payload to communicate via UWB. The transmitting UWB device may select, based on the number of information bits, a codeword length from a selection of available codeword lengths with which to encode the payload using a low-density parity-check (LDPC) encoding scheme, wherein the selection of available codeword lengths include a first codeword length, a second codeword length, and a third codeword length, wherein the third codeword length is longer than the second codeword length, which is longer than the first codeword length. The transmitting UWB device may transmit the payload using one or more codewords having the selected codeword length.

Abstract: In some implementations, a ultra-wideband (UWB) device comprises a Global Anchor for a network of UWB anchors having a plurality of clusters and initiator anchors (Init-Anchors). The Global Anchor may obtain metric information comprising a centrality metric value of each Init-Anchor from information communicated to the Global-Anchor in a first control phase. The Global Anchor may determine a slot schedule for a second control phase, wherein: determining the slot schedule is based on the centrality metric values of the plurality of Init-Anchors; the slot schedule comprises an allocation of time slots of the second control phase among the plurality of Init-Anchors for wireless radio frequency (RF) communication; and the allocation of time slots includes a first set of time slots for upstream communication followed by a second set of time slots for downstream communication. The Global Anchor may send the slot schedule to an Init-Anchor of the plurality of Init-Anchors.
