Method and Apparatus for Controlling Use of Tracking Reference Signals by User Equipments in a Wireless Communication Network - A simplified explanation of the abstract

This abstract first appeared for US patent application 18257902 titled 'Method and Apparatus for Controlling Use of Tracking Reference Signals by User Equipments in a Wireless Communication Network

Simplified Explanation

The techniques disclosed in this patent application involve prohibiting the use of configured Tracking Reference Signals (TRSs) by a User Equipment (UE) under certain conditions or circumstances. Instead, the UE is directed to use Demodulation Reference Symbols (DMRS) for time or frequency tracking when TRS usage is prohibited for reception of a physical downlink channel.

  • TRS usage is prohibited for time or frequency tracking for reception of a physical downlink channel.
  • UE is directed to use DMRS for time or frequency tracking in such scenarios.

      1. Potential Applications
  • Wireless communication systems
  • Mobile networks
  • 5G technology
      1. Problems Solved
  • Ensures efficient use of resources
  • Improves signal reception quality
  • Enhances overall network performance
      1. Benefits
  • Better utilization of TRS and DMRS
  • Enhanced tracking capabilities
  • Improved reliability of signal reception


Original Abstract Submitted

Techniques disclosed herein provide for prohibiting use by a User Equipment (UE) () of configured Tracking Reference Signals (TRSs) (). For example, under certain conditions or circumstances, the UE () is prohibited from using any configured TRS () for time or frequency tracking, for reception by the UE () of a physical downlink channel (). For example, when TRS usage is prohibited for time or frequency tracking for reception of a physical downlink channel (), the UE () uses Demodulation Reference Symbols (DMRS) transmitted for the physical downlink channel (), for such time or frequency tracking.
