Abstract: Techniques are provided for determining the location of ultrawideband (UWB) devices in a network. An example method for providing location information associated with a target device in a UWB network includes determining a location of a bridge device, querying the bridge device for location information associated with the target device, receiving location information associated with the target device from the bridge device, and determining a location of the target device based at least in part on the location of the bridge device and the location information associated with the target device.

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 systems, devices, apparatus, and methods, including computer programs encoded on storage media, related to low power techniques for a BLE device during a scanning state. The BLE device is configured to scan for a preamble of a packet while in a first power mode and detect when a bit of the preamble is received. Upon detecting that the bit of the preamble is received, the BLE device switches from the first power mode to a second power having a higher operating power for the BLE device than the first power mode. The switch in power modes occurs while the preamble is being received or immediately after the preamble is received and before an access address of the packet is received. The BLE device, while in the second power mode, then scans for the access address of the packet.
