Abstract: An electronic device can perform a process for conducting first ranging measurements with a first plurality of electronic devices to obtain first ranging information for a first peer-to-peer coordinate system, the first ranging information providing first relative location information between the mobile device and a first plurality of electronic devices. The method may include generating, using the first ranging information, a first relative location for the mobile device in the first peer-to-peer coordinate system. The device may conduct a second ranging measurements with a second plurality of electronic devices to obtain second ranging information for a second peer-to-peer coordinate system, the second ranging information providing second relative location information between the mobile device and a second plurality of electronic devices, where the first plurality of electronic devices are not within peer-to-peer communication range with the second plurality of electronic devices.

Abstract: User equipment (UE) may determine a probability that a cellular network may allocate a resource block to the UE having a frequency that, when a cellular transmitter of the UE transmits a radio frequency (RF) signal using the resource block, a harmonic signal may be generated that interferes with a global navigation satellite systems (GNSS) signal received by a GNSS receiver of the UE. The probability may be determined based on a number of factors that may impact resource block allocation, including a location of the UE, a current date and/or time, a historical allocation of resource blocks (which may be crowdsourced), a client type associated with a signal to be transmitted, a signal environment at the UE, real world conditions, and so on. Based on the probability, the UE may selectively perform a mitigation procedure or transmit an RF signal without performing the mitigation procedure.

Abstract: A mobile device may determine a set of range values between the first mobile device and the second mobile device based on a difference between the first time and the second time for ranging wireless signals. The mobile device can determine first odometry information using a first sensor on the first mobile device, the first odometry information indicating a first motion of the first mobile device during a time period. The mobile device can receive, via a data channel, second odometry information determined from second measurements captured using a second sensor on the second mobile device. The mobile device can solve an angle between a first reference frame for the first device and a second reference frame for the second device using the set of range values, and the first and second odometry information to display a directional arrow pointing to a current position of the second mobile device.
