ZTE has announced the completion of tests in seven major scenarios that are part of the second phase of China’s National 5G tests. Phase 2 of China’s National 5G tests, organized by IMT-2020 (5G) Promotion Group, were conducted in Huairou in Beijing. 

ZTE completed tests for continuous wide coverage, eMBB (enhanced mobile broadband) at sub-6Ghz, eMBB at millimeter-wave frequencies, uRLLC (ultra-Reliable and Low Latency Communications), eMTC (massive Machine Type Communications), in addition to two hybrid scenarios.

In the eMBB@Sub6GHz test scenario, ZTE provided 28 streams for multiple users by using the 3.5 GHz pre-commercial base station, with a peak cell throughput higher than 19 Gbps. ZTE also used 26GHz base station in the high-frequency eMBB test scenario, and achieved a 4-stream rate of 13 Gbps even when a single test terminal supported a bandwidth of less than 1 GHz.

In the mMTC test scenario, ZTE increased the overload rate of connected terminals by 600 percent by using the innovative MUSA (multi-user shared access) technology, and verified an equivalent massive IoT access performance of 90 million connections/MHz/hour/km2. mMTC is one of the three key scenarios defined in 3GPP standards. 

In the uRLLC test scenario, ZTE achieved an ultra-low latency of 0.416 ms based on a unified test platform. According to company, the system is based on ZTE's self-developed chipsets, which is self-adaptable in eMBB and uRLLC scenarios.

In the hybrid test scenarios, ZTE created a unified network supporting the air interfaces in eMBB, mMTC, and uRLLC scenarios through network slicing and base stations at sub-6GHz. This achieved flexible configuration of services, allowing a cell to connect a variety of service terminals. Test results showed that the single-cell peak rate reached 15 Gbps, while the air interface latency was lower than 0.416 ms, and the massive connectivity capacity was more than 90 million connections/MHz/hour/km2 at the same time. 

According to ZTE, company is committed to driving the commercialization of 5G products, laying a solid foundation for commercial 5G deployment in China by 2020.
