Qualcomm, Samsung & KT Conduct Successful 5G NR Test

KT, Qualcomm, and Samsung achieve multi-vendor 5G NR interoperability testing


Telecom operator KT Corporation, in collaboration with Samsung and Qualcomm Technologies, has achieved multi-gigabits downlink speeds and a very low 1-millisecond latency during the multi-vendor 5G NR interoperable testing. The companies boast the test is a significant milestone in the rollout of 5G.

These fiber-like speeds and low latencies will be essential to meeting the increasing connectivity requirements of emerging mobile broadband experiences such as virtual/augmented reality, as well as enabling new high-reliability, low-latency services for industrial control, autonomous vehicles and drones, among other use cases, stated the announcement.

The live, over-the-air interoperable testing demonstrated data connections operating in 3.5 GHz and 28 GHz bands, utilizing pre-commercial 5G NR base stations from Samsung and 5G NR UE prototypes from Qualcomm Technologies.


The achievement is a significant milestone on the path to standard-compliant mobile 5G NR trials starting in 2018, leading to commercial 5G NR network deployments and multimode smartphone launches anticipated in 2019.

“KT has worked closely with Samsung and Qualcomm Technologies on testing innovative mobile technologies,” said Seo, Chang-Seok, EVP and Head of Network Strategy Unit, KT. “KT believes that this 5G NR trial will pave the way to a successful launch of 5G NR networks and mobile devices, which will mark another technology breakthrough beyond the first broad-scale 5G trial services at the 2018 PyeongChang Winter Olympic Games.”

The end-to-end 5G NR interoperability testing demonstrated the essential components of the 5G NR air interface — fully compliant with 3GPP Release-15 5G NR specifications
These include scalable 5G NR OFDM numerology, advanced 5G NR channel coding and modulation schemes, low-latency 5G NR slot structure and 5G NR control and data channel support for Massive MIMO and mobile mmWave.

The 5G NR interoperability demonstration will be on display at MWC in Barcelona from February 26 through March 2.
