Rohde & Schwarz achieves highest number of GCF validated 3GPP NR NTN test cases for RF, RRM and PCT domains

Rohde & Schwarz achieves highest number of GCF validated 3GPP NR NTN test cases for RF, RRM and PCT domains Rohde & Schwarz is at the forefront of GCF validated 3GPP NR NTN conformance, delivering industry leading performance across RF, RRM and PCT domains.

At the core of NR-NTN conformance test solutions: the CMX500 OBT.

Rohde & Schwarz is driving the commercialization of 5G-based New Radio non-terrestrial networks, having successfully validated the highest number in GCF conformance test cases for NR-NTN to this date. The validation covers all three domains, RF, RRM and PCT, as defined in 3GPP Release 17, and was presented at the recent Global Certification Forum meeting CAG #86 in D sseldorf.

Following the successful validation of the first 5G-based NR-NTN at the PTCRB (PCS Type Certification Review Board), Rohde & Schwarz continued its efforts to enable validation at the GCF (Global Certification Forum). The validated test cases within GCF WI-555 (Work Item) are defined in accordance with the 3GPP test specifications for RF (Radio Frequency), RRM (Radio Resource Management) and PCT (Protocol Conformance Testing) and were executed with Rohde & Schwarz conformance test solutions.

All measurements were conducted on the R&S TS8980 Conformance Test Platform, the R&S TS-RRM and the CMX500 in frequency range 1 (FR1) verifying the latest NR-NTN chipset from Samsung as device under test (DUT).

3GPP conformance testing is essential for ensuring that devices and networks comply with global standards. 5G NR-NTN testing presents challenges that extend beyond those encountered in traditional terrestrial networks, primarily due to the vastly different operating environment and the dynamic nature of satellite-based communication.

At the core of the Rohde & Schwarz conformance test solutions is the CMX500 5G one-box signaling tester, which also supports early research and development through integrated fading and channel emulation, along with an intuitive tool for visualizing satellite constellations - all in a single-box test setup. In addition, the user-friendly R&S CONTEST test system software platform facilitates the seamless execution of 3GPP test cases.
