Abstract: Techniques for controlling remote antenna systems. An example method of receiving radio frequency signals with a remote antenna module includes providing a first signal to a remote receiver on a conductor, receiving a control signal from the remote receiver on the conductor, wherein the control signal is a bias voltage on the conductor, and providing a second signal on the conductor in response to receiving the control signal.

Abstract: Methods, systems, computer-readable media, and apparatuses for determination of multipath for determining a location of user equipment (UE) are presented. In some embodiments, the UE may, based on a first indication of signal strength associated with a first polarization type, and a second indication of signal strength associated with a second polarization type, determine an indication of multipath reflection along a path of signal propagation between a space vehicle (e.g., GNSS satellite) and the UE. Circularly polarized positioning signals may be received by the UE via natively present linearly polarized antennas and converted into circularly polarized signals. Converted circularly polarized signals may include right-handed and left-handed components, and signal strengths for each component may be compared to determine the presence of multipath. Positioning signals may be given a weight or disregarded based on the multipath determination when determining the position of the UE.

Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System and communication system operation, e.g. enabling an SPS receiver to continue to receive SPS signals in frequency bands that are interfered with due to aggressor transmission signals. A controllable filter, such as a selectable and/or tunable notch or lowpass filter is used to reject the aggressor transmission signals. The controllable filter may also attenuate some, but not all, frequencies in the SPS L1 band. To avoid losing complete access to these filtered SPS signal frequencies, the controllable filter is controlled, e.g., selected or tuned to these frequencies only when the aggressor transmission signal is active, and is otherwise turned off or tuned away from the SPS signal frequencies.
