Abstract: Techniques and apparatuses are described that implement a radio-frequency front-end (RFFE) circuit for location services and wireless communication. In an example aspect, a computing device includes a radio-frequency front-end circuit, which is used to provide location services via a global navigation satellite system and wireless communication via a non-terrestrial network. In one aspect, an architecture of the radio-frequency front-end circuit supports the concurrent reception of signals for location services and wireless communication. This allows location information to be updated for proper timing adjustment during a downlink time interval. At least some components of the radio-frequency front-end circuit have a shared-use and operate on signals that are received for location services as well as signals that are received for wireless communication. In another aspect, the radio-frequency front-end circuit uses a switching circuit to provide a relatively simple and inexpensive means of coexistence management.

Abstract: This document describes techniques, apparatuses, and systems for adaptive wireless transmitter power control for GNSS interference mitigation. This document addresses interference degradation in GNSS operations of computing devices due to integration of a variety of radio interference aggressors in the same platform. A GNSS subsystem is disclosed that may assert power back-off requests to reduce the power of one or more RAT transmitters and limit signal degradation during GNSS subsystem operations. Qualities of the satellite signals received at the GNSS subsystem may be analyzed to determine if it is appropriate to assert or deassert the power back-off requests. In this way, the described techniques, apparatuses, and systems for adaptive wireless transmitter power control for GNSS subsystems may adaptively manage GNSS subsystem operations and other RATs to reduce GNSS signal degradation due to interference.
