5G Measurements: UE and Base Station Testing Overview

5g measurement ue base station conformance testing

This page provides an overview of 5G measurements performed on User Equipment (UE) and Base Stations (BS) or Nodes B (NB). It details both 5G UE measurements and 5G BS measurements.

The 5G measurements encompass both transmitter and receiver test scenarios.

Introduction:

The following tests are generally performed during 5G measurements:

  • Transmitter conformance measurements
  • Receiver conformance measurements
  • Measurements during Inter-operability tests
  • Network Stability measurements
  • Inter-RAT measurements
  • Drive test measurements
  • Near field and far field measurements
