PRS Muting for Location Estimation of Reduced Capacity Devices - A simplified explanation of the abstract

This abstract first appeared for US patent application 17885434 titled 'PRS Muting for Location Estimation of Reduced Capacity Devices

Simplified Explanation

Apparatuses, systems, and methods for positioning reference signals (PRSs) for reduced capacity devices, such as in 5G NR systems and beyond, are disclosed in this patent application.

  • A UE may receive a reference signal configuration for the positioning procedure from a network, based on capabilities reported by the UE.
  • The reference signal configuration may support coherent stitching with tone-overlap.
  • The UE may receive downlink positioning reference signals and mute at least a portion of the resources.
  • Muting a portion of PRS resources may generate a phase discontinuity, but transmission of PRS resources can continue without regard to the phase discontinuity or be shifted to account for it.
  • Shifting the PRS transmission to account for the phase discontinuity ensures that the PRS transmission remains in phase with the transmission that occurred immediately prior to the muted portion.

      1. Potential Applications
  • This technology can be applied in 5G NR systems and beyond for positioning reference signals for reduced capacity devices.
      1. Problems Solved
  • Addressing phase discontinuities caused by muting portions of PRS resources in downlink positioning reference signals.
      1. Benefits
  • Improved accuracy in positioning reference signals for reduced capacity devices.
  • Enhanced performance in 5G NR systems and beyond.


Original Abstract Submitted

Apparatuses, systems, and methods for positioning reference signals (PRSs) for reduced capacity devices, e.g., in 5G NR systems and beyond. A UE may be configured to may receive, from a network (e.g., from a base station and/or an LMF) a reference signal configuration for the positioning procedure, e.g., based on one or more capabilities reported by the UE. The reference signal configuration may support coherent stitching (e.g., frequency hopping) with tone-overlap. Additionally, the UE may be configured to receive downlink positioning reference signals and mute at least a portion of downlink positioning reference signal resources. A phase discontinuity may be generated by muting at least the portion of PRS resources and transmission of the PRS resources may continue without regard to the phase discontinuity or transmission of the PRS resources may be shifted to account for the phase discontinuity such that a PRS transmission immediately after the muted portion of PRS resources may be shifted to remain in phase with a transmission that occurred immediately prior to the muted portion of the PRS resources.
