UE SIGNAL TO INTERFERENCE POWER RATIO DETECTION FOR NETWORK SCHEDULING ASSISTANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17902663 titled 'UE SIGNAL TO INTERFERENCE POWER RATIO DETECTION FOR NETWORK SCHEDULING ASSISTANCE

Simplified Explanation

The patent application describes techniques for measuring and detecting the signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may contain a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE filters out the interferences and in-band blocker to determine the power of the desired signal and the co-channel interference separately.

  • The UE determines the total power of the received signal, including the desired signal and co-channel interference.
  • The UE deactivates the uplink transmission to eliminate interference and receives the desired signal again.
  • The UE calculates the SIR by comparing the total power with the power of the desired signal.

Potential applications of this technology:

  • Wireless communication systems
  • Mobile devices
  • Internet of Things (IoT) devices

Problems solved by this technology:

  • Accurate measurement and detection of the signal-to-interference ratio in the presence of various interferences.
  • Separation of the desired signal and co-channel interference that overlap in frequency.

Benefits of this technology:

  • Improved signal quality and reliability in wireless communication.
  • Enhanced performance of mobile and IoT devices in noisy environments.
  • Better utilization of available frequency spectrum.


Original Abstract Submitted

Embodiments disclosed herein relate to techniques for measuring and/or detecting a signal-to-interference ratio (SIR) of a received signal at a user equipment (UE). The received signal may include a desired signal, co-channel interference, adjacent channel interference, and an in-band blocker. The UE may filter (e.g., remove) the various interferences and in-band blocker. The UE may determine or measure a power (or Received Signal Strength Indicator (RSSI)) of the desired signal and a power (or RSSI) of the co-channel interference separately because the desired signal and the co-channel interference overlap in frequency. To do so, the UE may determine a total power of the received signal including the desired signal and co-channel interference. The UE may receive the desired signal again while an uplink transmission is deactivated (and thus without the interference). The UE may then calculate the SIR based on the total power and the power of the desired signal.
