Embodiment Construction

[0020] Rather than having a Global Navigation Satellite System (GNSS) receiver blank or otherwise ignore GNSS signals when one or more Radio Access Technology (RAT) transceivers are transmitting, analysis can be performed by the Coexistence Manager (CxM) to determine How position (location) determination and / or transmission by one or more RAT transceivers is handled. It may be desirable to determine the location of a mobile device when one or more RAT transceivers on which the one or more RAT transceivers and a GNSS receiver are located are transmitting. Such position determination may be desirable even if there is an amount of interference with reception of GNSS signals by a GNSS receiver due to transmission of wireless signals by one or more RAT transceivers.

[0021] A number of factors may affect whether transmissions by a RAT transceiver cause significant interference to reception of GNSS signals by a GNSS receiver. In some cases, frequencies used by RAT transceivers may...

Abstract

Various arrangements are presented for managing coexistence of a global navigation satellite system (GNSS) receiver with a radio access technology (RAT) transceiver. A coexistence manager may receive an indication of a characteristic of a RAT transceiver for a scheduled operating event. Based on the characteristic of the RAT transceiver for the operating event, the coexistence manager may select a space vehicle of a GNSS to use for a location determination by the GNSS receiver. The GNSS receiver may then receive a signal from the space vehicle of the GNSS during the operating event of the RAT transceiver. Location determination using the signal received from the space vehicle received during the operating event of the RAT transceiver may then occur.

Description

Background technique [0001] Conventionally, when a Radio Access Technology (RAT) transceiver transmits data wirelessly via an antenna, a Global Navigation Satellite System (GNSS) receiver located on the same device may not be able to process the received GNSS signals for performing The location is OK. When transmitting, RAT transceivers may in some cases generate a sufficient amount of noise to adversely affect the ability of a GNSS receiver to properly receive and process GNSS signals. When the RAT transceiver is transmitting, the GNSS receiver may be instructed to blank or otherwise ignore received GNSS signals. Such arrangements can create significant periods of time during which position determination cannot be performed by the GNSS receiver. This occurrence can be exacerbated if there are multiple RAT transceivers on the device. Contents of the invention [0002] In some embodiments, a method for managing coexistence of a Global Navigation Satellite System (GNSS) rec...
