Protocol conformance toolset gets 3GPP thumbs-up

Keysight Technologies says that it is the first company to gain approval from 3GPP  for 5G new radio (NR) test cases that support carrier aggregation (CA) technology, using its Protocol Conformance Toolset.

Keysight's test cases were submitted on March 21, 2020 and verified by the 3GPP's RAN 5 working group, which works to establish conformance testing specifications for the radio interface of a user equipment (UE).

Chipset and device makers rely on 3GPP-verified 5G NR protocol CA test cases to verify designs that use CA to increase bandwidth and support higher data rates.

These test cases focus on 5G NR deployments using CA in non-standalone (NSA) and standalone (SA) mode in frequency range 1 (FR1) and FR2.

Keysight then submitted these test cases for verification at the most recent Conformance Agreement Group (CAG) #62 meeting, led by the Global Certification Forum (GCF) on April 23, 2020.

There it was confirmed that Keysight's Protocol Conformance Toolset maintains support for the widest range of GCF-validated protocol conformance test cases.

Comprehensive test case support enables device makers to leverage Keysight's common solution platform to verify designs that use different modes to address global requirements.

"Keysight consistently supports the development of 5G technologies, such as carrier aggregation, enabling a connected mobile ecosystem to market devices that support advanced 5G applications," said Kailash Narayanan, vice president and general manager of Keysight's wireless test group. "Many mobile device makers use Keysight's 5G solutions to access a comprehensive range of validated test cases for GCF certification across multiple technologies, including 5G NR, LTE and C-V2X, on a common solution platform."

Following the GCF meeting, it was confirmed that Keysight's RF/RRM DVT & Conformance Toolset, part of the company's suite of 5G network emulation solutions, offers a leading number of GCF-validated 5G NR radio frequency (RF) test cases and bands.

The toolset delivers GCF-validated RF test cases that enable users to verify compliance to the C-V2X standard as specified by 3GPP.

As a result, the automotive industry can accelerate commercialisation of connected cars and autonomous vehicles.
