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: 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: 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.
