Sagar Parsawar requested to merge nr_prs into develop
  • Rel16 Positioning reference signal(PRS) generation in OAI gNB
  • PRS based Channel estimation at OAI nrUE
  • Time of arrival(ToA) estimation at nrUE based on channel impulse response(time domain)
  • Finer ToA estimation by 16x oversampled IDFT for channel impulse response
  • T tracer dumps for PRS channel estimates
  • FR1, FR2 gNB and UE configs for PRS testing
  • Multiple gNB scenario validated with gNBs synced via GPSDO
  • In FR1 and FR2 modes, PRS signal is successfully decoded on Spectrum Analyser R&S Rel16 version
