Abstract: A method for locating a target object includes: determining a plurality of position-orientation-distance-angle values, each including: a position of a user equipment (UE) relative to a reference position; an orientation of the UE relative to a reference orientation; a distance corresponding to the position of the UE, the distance being between the position of the UE and the target object based on wireless ranging signal(s) between the UE and the target object; and an angle corresponding to the position and orientation of the UE, the angle being an AoA of the wireless ranging signal(s) at a first and second antenna of the UE, where a combination of the position and orientation of the UE in each of the position-orientation-distance-angle values is different; and calculating a position of the target object using the plurality of position-orientation-distance-angle values, where the position of the target object is relative to the reference position.

Abstract: Certain aspects of the present disclosure provide techniques reducing wireless interference in wireless communications networks by, for example, enabling a coexistence period during which transmission over a first wireless communication band is deprioritized and reception over a second wireless communication band, different from the first wireless communication band, is prioritized; and receiving positioning data from a positioning system via the second wireless communication band during the coexistence period.

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: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

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: 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: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.
