Qualcomm Technologies, ZTE and China Mobile have achieved the world’s first end-to-end 5G NR Interoperability Data Testing (IoDT) system demonstrating a data connection based on 3GPP R15 standard. Following the guidelines of China Mobile, the IoDT connection demonstration took place at China Mobile’s 5G Joint Innovation Center, and utilized ZTE’s 5G NR pre-commercial base station and Qualcomm Technologies’ 5G NR sub-6 GHz UE prototype.
The end-to-end 5G NR system operates in the 3.5 GHz band and supports 100 MHz bandwidth, compliant with the 3GPP Release-15 5G New Radio layer 1 framework — including the scalable OFDM numerology, new advanced channel coding and modulation schemes, and the low-latency self-contained slot structure. The end-to-end 5G NR IoDT system is designed to efficiently achieve multi-gigabit per second peak data rates at significantly lower air interface latency than 4G networks.
“Implementation of 5G NR technologies will be critical to meeting the increasing connectivity requirements of emerging mobile broadband experiences such as streaming high-definition video and immersive virtual/augmented reality in the future, as well as enabling new high-reliability, low-latency services for autonomous vehicles, drones and industrial control, etc.,” said Cristiano Amon, executive vice president, Qualcomm Technologies, Inc., and president, QCT
The successful interoperable connection of the end-to-end 5G NR IoDT system serves as an industry milestone toward pre-commercialization of 5G NR technologies at scale, driving rapid development of 3GPP standards-compliant networks and devices.
