This makes ZTE one of the leading IMT-2020 (5G) providers that successfully completed high-frequency communication and massive MIMO technology tests.
The Chinese IMT-2020 (5G) Promotion Group has developed an experimental 5G technology research and development (R&D) plan to combine the strengths of companies, universities, and research institutes. This initiative aims to boost research into 5th generation mobile technologies in China and foster international exchange and cooperation. From 2016 to 2018, the plan will be implemented in three phases: testing, verification, and global 5G system verification.
The first phase began in September 2015 and will conclude in September of this year, focusing on the verification of key technologies and performance testing. ZTE, as a core member of the IMT-2020 (5G) promotion group, has actively participated and cooperated in all group activities. Since the inception of the 5G technology R&D experiment, ZTE has been fully involved in the discussion and formulation of the tests. The company also launched its own 5G Phase I test four months prior, based on its own product R&D and testing plan.
During the last two weeks of May, ZTE completed verification and performance tests of its two most important 5G technologies in different cities: High Frequency Communication (HFC) in Shanghai and Massive Single-Site MIMO (MSM) in Shenzhen. Both tests were successful.
For the first section, single-user performance was tested at different signal-to-noise ratios in an indoor line-of-sight (LOS) environment. The results matched the expected theoretical values, and the advanced mezzanine card (AMC) functions worked correctly. Later, single-user performance was tested at different signal-to-noise ratios in a non-line-of-sight (NLOS) environment. The NLOS tests included transmission through glass, iron plate, and reflection from glass and iron plate, very similar to the actual environment. As a result, single-user performance at different signal-to-noise ratios met the theoretical expectations, and the AMC functions worked correctly. Furthermore, ZTE plans to conduct high-frequency communication tests outdoors.
The test demonstrated that in massive MIMO NodeBs (eNBs), cell yields can be exponentially increased, with downstream gains up to three times greater than in conventional macrocell base stations. Meanwhile, considering that massive MIMO upstream capacity can be limited, ZTE conducted tests to assess its effectiveness. The results showed that this technology could help increase cell performance, achieving upstream gains four times higher than previously possible. To date, ZTE is the only vendor to have conducted massive MIMO upstream testing. This demonstrates ZTE's undeniable expertise and strength in this field.
As a global pioneer in 5G technology, ZTE aims to become one of the first commercial equipment providers by 2020. To date, it has successfully completed the high-frequency communication and massive MIMO technology verification and performance tests organized by the Chinese IMT-2020 (5G) Promotion Group. This further demonstrates ZTE's strength and positioning in the 5G field.
