Abstract
Methods, systems, computer-readable media, and apparatuses for to managing use of a satellite positions system (SPS) receiver in conjunction with one or more radio access technology (RAT) transmitters. In certain embodiments, a controller can be used to prioritize reception by the SPS receiver over transmission by the one or more RAT transmitters.
Claims21
An apparatus, comprising:
- an antenna;
- a satellite positioning system (SPS) receiver coupled with the antenna;
- a radio access technology (RAT) transmitter coupled with the antenna;
- and
- a controller communicatively coupled to the SPS receiver and the RAT transmitter, wherein the controller is configured to:
- determine whether the SPS receiver is receiving a first signal via the antenna to determine a location of the SPS receiver;
- and
- in response to determining that the SPS receiver is receiving the first signal via the antenna, induce the RAT transmitter to either:
- (a) delay a second signal from being transmitted by the RAT transmitter via the antenna while the first signal is being received by the SPS receiver via the antenna or the location of the SPS has not been determined;
- or
- (b) transmit the second signal at a low power level via the antenna while the first signal is received by the SPS receiver via the antenna, the low power level determined to allow reception of the first signal by the SPS receiver via the antenna,
- wherein the apparatus does not include a filter coupled between the antenna and each of the SPS receiver and the RAT transmitter to physically separate the first signal from the second signal.

A method, comprising:
- determining whether a SPS receiver is receiving a first signal via an antenna to determine a location of the SPS receiver;
- and
- in response to the determination that the SPS receiver is receiving the first signal via the antenna, inducing a RAT transmitter to either:
- (a) delay a second signal from being transmitted by the RAT transmitter via the antenna while the first signal is received by the SPS receiver via the antenna and the location of the SPS has not been determined;
- or
- (b) transmit the second signal at a low power level via the antenna while the first signal is received by the SPS receiver via the antenna, the low power level determined to allow reception of the first signal by the SPS receiver via the antenna, wherein a signal path between the antenna and each of the SPS receiver and the RAT transmitter does not include a filter to physically separate the first signal from the second signal.
3 more elements
A non-transitory computer readable medium containing instructions that, when executed by one or more processors, cause the one or more processors to:
- determine whether a SPS receiver is receiving a first signal via an antenna to determine a location of the SPS receiver;
- and
- in response to the determination that the SPS receiver is receiving the first signal via the antenna, induce a RAT transmitter to either:
- (a) delay a second signal from being transmitted by the RAT transmitter via the antenna while the first signal is received by the SPS receiver via the antenna and the location of the SPS has not been determined;
- or
- (b) transmit the second signal at a low power level via the antenna, the low power level determined to allow reception of the first signal by the SPS receiver via the antenna, wherein a signal path between the antenna and each of the SPS receiver and the RAT transmitter does not include a filter to physically separate the first signal from the second signal.
3 more elements
An apparatus, comprising:
- means for determining whether a satellite positioning system (SPS) receiver is receiving a first signal via an antenna to determine a location of the SPS receiver;
- and
- means for, in response to the determination that the SPS receiver is receiving the first signal via the antenna, induce a RAT transmitter to either:
- delay a second signal from being transmitted by the RAT transmitter via the antenna while the first signal is received by the SPS receiver via the antenna and the location of the SPS has not been determined;
- or
- transmit the second signal at a low power level via the antenna while the first signal is received by the SPS receiver via the antenna, the low power level determined to allow reception of the first signal by the SPS receiver via the antenna, wherein a signal path between the antenna and each of the SPS receiver and the RAT transmitter does not include a filter to physically separate the first signal from the second signal.
