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 17504237 titled 'UE SIGNAL TO INTERFERENCE POWER RATIO DETECTION FOR NETWORK SCHEDULING ASSISTANCE
Simplified Explanation
The patent application describes techniques for measuring 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 based on the total power and the power of the desired signal.
Potential applications of this technology:
- Wireless communication systems
- Mobile devices and smartphones
- Internet of Things (IoT) devices
Problems solved by this technology:
- Accurate measurement 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
- Enhanced performance of wireless communication systems
- Better user experience in terms of call quality and data transmission speed
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.
