What is 5G NR?

5G NR, or 5G New Radio, is the latest standard for cellular technology. It is designed to deliver higher data rates, lower latency, and improved reliability compared to previous generations of cellular technology. It uses a variety of technologies, including advanced antenna systems, millimeter-wave frequencies, and massive MIMO, to achieve these goals.


Why is Conformance Testing Important?

Conformance testing is a critical aspect of ensuring that new technologies meet certain standards. In the case of 5G NR, conformance testing is essential to ensure that devices and networks are compliant with the 5G NR standard. This is crucial for ensuring interoperability between different devices and networks and for ensuring that users can enjoy the full benefits of 5G NR technology.


Types of 5G NR Conformance Testing

There are several types of conformance testing for 5G NR, including:

  • Protocol conformance testing: This tests the compliance of devices and networks with the 5G NR protocol specification.

  • Radio frequency (RF) conformance testing: This tests the RF performance of devices and networks, including their ability to transmit and receive signals.

  • Radio resource management (RRM) conformance testing: This tests the RRM functionality of devices and networks, including their ability to allocate resources and manage interference.

5G NR Conformance Test Cases

There are several conformance test cases that devices and networks must pass to be considered compliant with the 5G NR standard. These test cases cover various aspects of the 5G NR protocol, including:

  • Physical layer: This includes tests for uplink and downlink transmission, modulation, coding, and synchronization.

  • Medium access control (MAC) layer: This includes tests for random access, scheduling, and hybrid automatic repeat request (HARQ).

  • Radio link control (RLC) layer: This includes tests for segmentation, reassembly, and error correction.

  • Packet data convergence protocol (PDCP) layer: This includes tests for header compression, encryption, and integrity protection.

  • Radio resource control (RRC) layer: This includes tests for connection establishment, mobility, and power control.

5G NR Conformance Test Suites

Conformance testing is typically performed using test suites that contain a set of predefined test cases. These test suites are developed by standardization organizations, such as 3GPP, and are used by test equipment vendors, network operators, and device manufacturers. Some examples of 5G NR conformance test suites include:

  • RAN5 5G NR Radio Conformance Testing: This test suite covers RF and protocol conformance testing for 5G NR devices, including UE and gNB.

  • RAN5 5G NR RRM Conformance Testing: This test suite covers RRM conformance testing for 5G NR devices, including UE and gNB.

  • PTCRB 5G NR Protocol Conformance Testing: This test suite covers protocol conformance testing for 5G NR devices that are intended to be certified by PTCRB.

5G NR Conformance Testing Equipment

To perform 5G NR conformance testing, specialized test equipment is required. This includes:

  • Signal generators: These generate test signals that are used to test the performance of devices and networks.

  • Signal analyzers: These analyze the signals generated by devices and networks to determine their performance.

  • Channel emulators: These simulate different radio channel conditions, including fading, interference, and noise, to test the robustness of devices and networks.

5G NR Conformance Test Procedures

The 5G NR conformance test procedures involve the following steps:

  • Test setup: The test equipment is configured to generate test signals and analyze the signals generated by the device or network being tested.

  • Test execution: The device or network being tested is subjected to a set of predefined test cases.

  • Test reporting: The results of the test cases are recorded, and a conformance test report is generated.

5G NR Conformance Test Reports

After completing the conformance testing, a test report is generated. This report contains information on the test cases performed, the results of each test case, and any failures or issues encountered during testing. The report is used to determine whether the device or network being tested is compliant with the 5G NR standard.


5G NR (New Radio) is a wireless communication standard that enables faster data speeds, lower latency, and greater capacity compared to its predecessors. Conformance tests are essential to ensure that devices and networks comply with the 3GPP (Third Generation Partnership Project) specifications for 5G NR.


Conformance test reports provide information on the performance of devices and networks based on these tests. These reports typically cover a range of criteria, such as radio frequency (RF) performance, protocol conformance, and interoperability. They are essential for device manufacturers, network operators, and regulators to ensure that products and services meet the required standards and specifications.


There are several organizations that provide 5G NR conformance testing services and produce test reports, including the Global Certification Forum (GCF), PTCRB (PCS Type Certification Review Board), and the 3GPP. The GCF and PTCRB are industry bodies that certify devices for global and regional markets, respectively, while the 3GPP develops and maintains the 5G NR standard.


If you are looking for specific 5G NR conformance test reports, you may need to contact the relevant organizations that have conducted the tests and produced the reports. Alternatively, you can search for publicly available reports on their websites or through other online resources.

Challenges and Limitations of 5G NR Conformance Testing

Conformance testing for 5G NR is a complex and challenging task, with several limitations and challenges. Some of these challenges include:

  • Lack of standardization: The 5G NR standard is still evolving, and there is a lack of standardization in some areas, making it challenging to develop comprehensive test cases.

  • Test equipment availability: 5G NR test equipment is relatively new, and there may be a limited supply, making it challenging to perform conformance testing.

  • Cost: 5G NR test equipment is expensive, making it challenging for smaller device manufacturers to perform conformance testing.

Future of 5G NR Conformance Testing

As the 5G NR standard continues to evolve, conformance testing will become more critical. With the introduction of new features and capabilities, new test cases will need to be developed to ensure compliance with the latest standard. Additionally, the availability and cost of test equipment are expected to improve, making it easier for device manufacturers to perform conformance testing.


As the 5G NR technology continues to evolve and more devices and networks become available, the future of 5G NR conformance testing is likely to focus on several key areas.

Firstly, there is likely to be an increased emphasis on testing for 5G standalone (SA) networks, which operate independently of 4G LTE networks. SA networks require different testing procedures and equipment compared to non-standalone (NSA) networks, which rely on 4G infrastructure for some functions.


Secondly, there will likely be a continued focus on testing for new 5G NR features and capabilities as they are introduced. For example, testing for millimeter-wave (mmWave) frequencies, which offer faster data speeds but have shorter ranges than lower frequency bands, will require specialized testing procedures and equipment.


Thirdly, there will likely be a greater emphasis on interoperability testing to ensure that devices and networks from different vendors can work together seamlessly. This will be particularly important as more devices and networks become available and as 5G NR technology becomes more widespread.


Finally, there will likely be an increased use of automation and artificial intelligence (AI) in conformance testing procedures. This will help to improve testing efficiency, reduce costs, and ensure that devices and networks meet the required standards and specifications.

Overall, the future of 5G NR conformance testing is likely to be shaped by the continued evolution of 5G NR technology and the growing demand for faster, more reliable, and more secure wireless communications.
