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: A user equipment (UE) includes a first communication component configured to use a first frequency band, such as ultra-wide band (UWB), and a second communication component configured to use an intermediate frequency (IF) band that overlaps with the UWB band, such as an IF millimeter wave (mmWave) band. The second communication component conducts an IF signal along an internal signal conduction line that may interfere with UWB processing. A processor of the UE is configured to detect an indication of such interference, and, in response to the indication of interference, control the second communication component to adjust a characteristic of the IF band signal to mitigate the interference, such as by reducing its signal strength. The amount by which the IF band signal strength is reduced may be controlled to achieve a desired tradeoff between various performance metrics, such as power consumption and quality of service.

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.

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.
