Radio-frequency front-end circuit for location services and wireless communication

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.
