KT Corporation, Qualcomm, and Samsung Electronics have completed multi-vendor 5G NR interoperable testing compliant with the 3GPP Release-15 Non-Standalone (NSA) 5G NR global standard.
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 prototype devices from Qualcomm.
The end-to-end 5G NR interoperability testing included 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 vendors reported multigigabit downlink speeds, as well as latencies as low as 1 millisecond.
“KT has worked closely with Samsung and Qualcomm Technologies on testing innovative mobile technologies,” said Seo, Chang-Seok, executive vice president 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.”
“As the industry works toward the goal of commercial launches of 5G NR products and networks in 2019, close collaboration among global mobile industry leaders on testing and successful trials are necessary to validate the technologies and continue to build and improve our capabilities,” said Cristiano Amon, president, Qualcomm Incorporated. “We are proud of our achievement with Samsung and KT and look forward to further collaboration on the path to making 5G a commercial reality.”
