SUPPORTING SCHEDULING OF SOUNDING REFERENCE SIGNALS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17920318 titled 'SUPPORTING SCHEDULING OF SOUNDING REFERENCE SIGNALS

Simplified Explanation

The patent application describes a method for transmitting a Sounding Reference Signal (SRS) for positioning in a wireless communication system. Here are the key points:

  • The user equipment (UE) receives scheduling information for the SRS, which includes multiple reserved occasions for transmission.
  • The UE selects the first available reserved occasion without any transmission restrictions or collisions to transmit the positioning SRS.
  • The UE does not transmit the SRS on any earlier reserved occasions that are not available or any subsequent reserved occasions.
  • The base station attempts to decode the SRS on each reserved occasion until it is successfully received.
  • Unused reserved occasions can be reassigned to other UEs or channels by the base station.
  • The base station reports positioning measurements with associated time stamps for the reserved occasion on which the positioning SRS was received.

Potential applications of this technology:

  • Wireless communication systems that require accurate positioning information, such as location-based services or asset tracking.
  • 5G and future generations of wireless networks that support advanced positioning techniques.

Problems solved by this technology:

  • Efficient utilization of reserved occasions for SRS transmission, ensuring that the positioning SRS is transmitted without collisions or restrictions.
  • Flexibility in selecting the first available reserved occasion, reducing delays in transmitting the positioning SRS.
  • Optimization of resource allocation by reassigning unused reserved occasions to other UEs or channels.

Benefits of this technology:

  • Improved accuracy and reliability of positioning information in wireless communication systems.
  • Enhanced efficiency in utilizing reserved occasions for SRS transmission.
  • Reduced delays in transmitting the positioning SRS, leading to faster and more responsive positioning measurements.


Original Abstract Submitted

A user equipment (UE) receives scheduling information for Sounding Reference Signal (SRS) for positioning that includes multiple reserved occasions to transmit the SRS. The multiple reserved occasions may be used on all or on only a subset of configured SRS resources. The UE transmits the positioning SRS on a reserved occasion that is first available for transmission, e.g., without collision or other restrictions of transmission of the SRS. The UE does not transmit the positioning SRS on any earlier reserved occasions that is not available or any subsequent reserved occasions. The base station may attempt to decode the SRS on each reserved occasion until the positioning SRS is transmitted. The base station may reassign unused reserved occasions to other UEs or to other channels. The base station may report positioning measurements with associated time stamps for the reserved occasion on which the positioning SRS was received.
