FREQUENCY TRACKING LOOP PULL-IN RANGE EXTENSION USING FREQUENCY ERROR WRAPAROUND DETECTION AND CORRECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17457894 titled 'FREQUENCY TRACKING LOOP PULL-IN RANGE EXTENSION USING FREQUENCY ERROR WRAPAROUND DETECTION AND CORRECTION

Simplified Explanation

The patent application describes methods and devices for wireless communication, specifically related to an apparatus called a UE (User Equipment).

  • The UE measures the frequency error from two pairs of pilot symbols received from a base station via a communication channel.
  • These measurements correspond to the first and second frequency error measurements.
  • The UE detects frequency wraparounds in both measurements, indicating a non-zero value.
  • If a frequency wraparound is present, the UE adjusts the corresponding frequency error measurement based on the wraparound.

Potential applications of this technology:

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

Problems solved by this technology:

  • Frequency errors in wireless communication can lead to signal degradation and loss of data.
  • Detecting and adjusting for frequency wraparounds helps improve the accuracy and reliability of wireless communication.

Benefits of this technology:

  • Improved signal quality and reliability in wireless communication.
  • Enhanced performance of mobile networks and IoT devices.
  • More efficient use of wireless spectrum.


Original Abstract Submitted

Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE. The apparatus may measure a frequency error from a first pair of pilot symbols and a second pair of pilot symbols received via a channel associated with communication between the UE and a base station, the measured frequency error from the first pair of pilot symbols and the second pair of pilot symbols corresponding to a first frequency error measurement and a second frequency error measurement. The apparatus may detect a first frequency wraparound in the first frequency error measurement and a second frequency wraparound in the second frequency error measurement. The apparatus may adjust the first frequency error measurement based on the first frequency wraparound or the second frequency error measurement based on the second frequency wraparound if the first frequency wraparound or the second frequency wraparound is the non-zero value.
