ZTE participates in second phase 5G testing led by China's MIIT

ZTE announced its participation in the second phase of 5G testing, carried out under the guidance of the Chinese government via the Ministry of Industry and Information Technology (MIIT), as well as advances through a number of technical verifications.

China's 5G testing is being led by China's MIIT and implemented by its IMT-2020 (5G) promotion group, with R&D activities divided into three phases: technology verification, technical solution verification and system verification. ZTE noted that the project entered the technical solution verification phase in 2017.

ZTE is participating in R&D work relating to a range of 5G new radio (NR) prototype products based on early key technology verification, and is now seeking to verify product functionality and performance in typical 5G scenarios in preparation for 5G commercial network deployments. For the latest phase of testing, ZTE is providing a series of 5G prototype products based on a new unified platform and is working with test equipment suppliers including Keysight and Rohde & Schwarz.

The technical solution verification centred on four key technologies, specifically: 5G NR operating at sub-6 GHz and mmWave bands, massive machine type communication (mMTC) and ultra-reliable low latency communications (uRLLC). The tests also included seven scenarios: continuous wide-coverage scenario; low-delay and high-reliability scenario; low-power and massive-connection scenario; hotspots at sub-6 GHz scenario; hotspots at mmWave scenario; and sub-6 GHz and mmWave hybrid networking scenario.

ZTE stated that as part of the process, in the prototype sub-6 GHz field it provided a new 3.5 GHz NR pre-commercial base station, with all entries passing the RF tests of the MIIT and the RF bandwidth of the base station reaching 200 MHz. In addition, the solution's volume, weight, power and other key features comply with requirements for pre-commercial networks.

Additionally, related field performance tests in Beijing have also commenced. In the mmWave field, ZTE launched a series of prototype products and claims that it has made significant progress in technical solutions, machine integration and other aspects pertaining to performance.

In a recent pre-test at the ZTE Shanghai Institute, ZTE showcased its latest 26 GHz base station at mmWave, where single-user peak rate of nearly 16 Gbit/s was achieved. In addition, ZTE conducted a 60 GHz prototype at mmWave comparison test. As well as developments in the fields of mMTC and uRLLC, ZTE has launched an improved enhanced mobile broadband (eMBB) platform based on its previous technology verification platform.


Following the completion of the first phase of China's 5G technology testing, the second phase and testing ongoing 5G tests in Beijing have been implemented, providing 5G NR at sub-6 GHz, mmWave and mMTC and uRLLC test conditions designed to support progress towards the future large-scale commercial use of 5G.
