CONCURRENT OPERATION OF SPS RECEIVER AND WIRELESS TRANSMITTER - A simplified explanation of the abstract

This abstract first appeared for US patent application 17937407 titled 'CONCURRENT OPERATION OF SPS RECEIVER AND WIRELESS TRANSMITTER

Simplified Explanation

A mobile device can perform both Satellite Positioning System (SPS) operation and wireless communications simultaneously, even when the uplink signals from the device interfere with the reception of SPS signals in certain frequency bands.

  • The mobile device checks if the SPS receiver has already acquired SPS signals and is in a tracking state.
  • If the SPS receiver is not in a tracking state, the device initiates an SPS acquisition procedure before starting the wireless communication session.
  • The SPS acquisition procedure continues until the SPS receiver reaches a tracking state or a timeout occurs.
  • Once the SPS receiver is in a tracking state, the wireless communication session can begin.
  • During the wireless communication session, the mobile device controls the SPS receiver to mitigate interference with SPS signals, such as by implementing signal blanking, measurement exclusion, or disabling SPS reception.

Potential Applications

  • This technology can be used in mobile devices such as smartphones, tablets, or wearables that rely on both SPS operation and wireless communications.
  • It can be beneficial for applications that require accurate positioning information while maintaining uninterrupted wireless communication, such as navigation, location-based services, or emergency response systems.

Problems Solved

  • The innovation addresses the issue of interference between uplink signals transmitted by a mobile device and the reception of SPS signals.
  • It ensures that the SPS receiver can acquire and track SPS signals even in the presence of interfering uplink signals, allowing for concurrent SPS operation and wireless communications.

Benefits

  • Users can enjoy uninterrupted wireless communication while still receiving accurate positioning information from the SPS receiver.
  • The technology improves the reliability and performance of mobile devices in scenarios where interference between SPS and wireless signals is a concern.
  • It enhances the overall user experience by enabling seamless integration of SPS operation and wireless communications.


Original Abstract Submitted

A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.
