Ensuring compliance with 5G requirements

Verifying a 5G device for RF / radio resource management (RRM) conformance requires running the conformance test cases defined by 3rd Generation Partnership Project (3GPP) specifications. Chipset and device makers may start testing in a pre-conformance phase before performing certification testing at an officially recognized lab. The Global Certification Forum (GCF) and PTCRB, part of the Cellular Telephone Industries Association (CTIA), support the most crucial certification programs that establish the conditions for test tool validation and lab accreditation. Additionally, devices must comply with supplementary local test requirements from mobile network operators (MNOs) or regulations. Creating and configuring a test plan is the first step in the testing process. Once the appropriate test plan is ready, test engineers can execute tests individually or sequentially.

Test engineers need an RF / RRM conformance toolset with superior RF measurement and real-time processing capabilities to support 5G's diverse requirements. The solution must enable RF testing in the target band, measure in the adjacent band and out of band for some tests, and generate interference for blocking test cases. Channel condition emulation and degradation, such as additive white Gaussian noise and fading profiles, are necessary. The solution must support the latest 3GPP release to enable users to establish a 5G call with a device under test in various 5G New Radio (NR) deployment modes (non-standalone and standalone) and frequency bands (FR1 and FR2).

5G RF / RRM conformance test solution

Testing a 5G device for RF / RRM compliance requires running compliance test cases validated by the GCF, PTCRB, and regulatory bodies. The Keysight 5G RF / RRM conformance test solution provides comprehensive, up-to-date access to NB non-terrestrial network, RedCap, 5G NR, and C-V2X RF and RRM conformance test cases as defined in 3GPP TS 38.521-1-5, 3GPP TS 38.533, and 3GPP TS 36.521. Using these test cases ensures that mobile devices perform as expected on a live network. The solution offers test cases validated by industry certification bodies and test plans from regulatory bodies. Complementary coverage for MNO certification tests is also available for ATT, T-Mobile, and Verizon.
