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 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.
