New 5G test cases developed to support China Mobile’s carrier acceptance test plan.

China Mobile made some interesting announcements about their 5G plans at Mobile World Congress 2022. This included the deployment of the network for both enterprise and commercial use cases.

China currently has more than 380 million 5G package subscribers as well as 300 million 5G terminal users on China Mobile’s network. The operator has also invested heavily to promote computing force as an on-demand, indispensable social service with one-click access.

Statistics show that China’s digital economy size is about 39.2 trillion yuan in 2020, registering a nominal year-on-year growth of 9.7%, much higher than the country’s nominal GDP growth at 6.7%. In December 2021, China had generated a cumulative revenue of about 120 billion yuan from its telecommunications industry.

As such, with demand for greater 5G services, Keysight Technologies has announced an extended range of 5G new radio (NR) test cases for device and module validation according to a carrier acceptance test (CAT) plan defined by China Mobile.

This comprehensive range of test cases is accessible using Keysight’s S8707A RF/RRM Carrier Acceptance Toolset (RCAT), part of the company’s suite of 5G network emulation solutions. The new test cases address multiple scenarios for validating the radio frequency (RF) and radio resource management (RRM) performance beyond specifications defined by 3GPP, the global standards organization. China Mobile’s carrier acceptance test program ensures 5G devices used by consumers and enterprises as well as in IoT applications perform as intended on the mobile operator’s network.

According to Muthu Kumaran, general manager of Keysight’s device validation solutions business, users of 5G network emulation solutions can now easily and cost-effectively access a wide range of RF/RRM carrier acceptance test cases for device validation according to China Mobile’s 5G CAT program. He added that the solution would also enable China Mobile to accelerate its commercial deployment of 5G technology.

Keysight offers a comprehensive range of CMCC RF/RRM test cases. Broad test case coverage on common hardware and software platforms facilitates mobile device verification across the RF workflow, from early modem development to device certification and carrier acceptance. It also supports CMCC defined test cases including verifying devices used on high-speed trains and in multiple-input multiple-output (MIMO) over-the-air (OTA) test scenarios.

With a global ecosystem consisting of 190 vendors of 5G devices, Keysight’s RCAT enables them to verify compliance to specifications mandated by standards organizations and major carriers before launching new products. The 5G UXM Wireless Test Platform enables chipset and device vendors, test houses and mobile operators to efficiently design, develop and validate, as well as gain carrier acceptance for new products by eliminating siloed data sets and sharing design insights gained across each stage of the wireless device lifecycle.

Meanwhile, Keysight’s UXM 5G platform supports RF characterization, protocol compliance, and functional key performance analytics for 5G NR non-standalone (NSA) and standalone (SA) mode. Users can seamlessly scale to address a diverse set of global spectrum requirements across frequency range 1 (FR1) and FR2 (mmWave) bands as defined by 3GPP.
