Abstract: Disclosed are systems and techniques for wireless communications. For example, a first user equipment (UE) can receive positioning data corresponding to a second UE. In some cases, the first UE can determine a relative position between the first UE and the second UE. In some aspects, the first UE can determine a first location estimate of the first UE based on the positioning data corresponding to the second UE and the relative position between the first UE and the second UE.

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: Techniques are provided for improving ranging accuracy of ultrawideband (UWB) devices. An example method for obtaining a distance measurement with a wireless node includes obtaining a first distance measurement using a first radio link, determining a status of a second radio link in response to the first distance measurement being less than a threshold distance, configuring one or more transceiver parameters associated with the second radio link in response to determining the second radio link is utilizing a non-line of sight path, and obtaining a second distance measurement using the second radio link and the one or more transceiver parameters.

Abstract: Systems and methods pertain to operating a receiver of wireless signals such as Bluetooth or Bluetooth Low Energy (BLE) signals. A correlator is provided to correlate a wireless signal received by the receiver with a device identifier corresponding to a wanted device from which the receiver wants to receive wireless signals, to generate a correlator output. An adaptive acquisition threshold generator generates an adaptive acquisition threshold based on a signal strength of the wireless signal, and a comparator is used to determine if the wireless signal is a wanted signal intended for the receiver, based on a comparison of the correlator output with the adaptive acquisition threshold.

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: The relative position of a user equipment (UE) within a vehicle is determined using angular measurements, such as angle of arrival (AOA), and optionally ranging measurements, with respect to a number of wireless transceivers within the vehicle using wideband signals. The relative position of the UE with respect to a personal zone or the steering wheel may be determined based on known positions of the wireless transceivers. If the UE is determined to be within the personal zone, at least one functionality of the UE is restricted to avoid driver distraction and, optionally, the operation autonomous driving of the vehicle adjusted. If the UE is worn on the driver's wrist the relative position of the UE with respect to the steering wheel may be similarly determined and operation of the vehicle modified if the UE is determined to be outside a threshold distance from the steering wheel.

Abstract: This disclosure provides methods, components, devices and systems for adjacent channel interference (ACI) mitigation techniques for ultra-wideband (UWB) systems. Some aspects more specifically relate to ACI mitigation for UWB systems. In some implementations, a wireless communication device may receive control information that identifies a preamble for communications to the wireless communication device in a UWB system. The wireless communication device may receive, via a signal in the UWB system, a data packet that includes the preamble. The wireless communication device may estimate a channel impulse response (CIR) of the signal and determine an interference metric that is based on the estimated CIR. The wireless communication device may process the data packet based on the interference metric.
