Phase 2 of China’s National 5G tests 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, achieving multiple breakthroughs:
eMBB@Sub6GHz Test: New Record for the Peak Value, with Cell Throughput Exceeding 19 Gbps
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, a new industry record. This data rate is higher than the ITU-defined value (10 Gbps). ZTE’s solution overcomes the limitations of standard interfaces, and provides more spatial division streams than the standard and common value (16 streams) in the industry. This technology is especially suitable for China’s densely-populated urban areas, highlighting ZTE’s technology leadership in 5G eMBB scenarios.
Industry-first eMBB@mmWave Test: Single-User Rate Exceeding 13 Gbps
ZTE was the first to use the 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. This rate is higher than that defined by ITU (10 Gbps), and is a major step forward in the development and commercialization of high-frequency mobile communications.
mMTC Scenario: Massive Capacity of 90 Million Connections/MHz/hour/km2
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, which is 90 times the value (1 million connections/square kilometers) currently defined by ITU. mMTC is one of the three key scenarios defined in 3GPP standards. ZTE plays a leading role in the NOMA (non-orthogonal multiple access) Working Group, serving to accelerate industry standardization of 5G globally.
uRLLC Scenario: Ultra-Low Latency of 0.416 ms
In the uRLLC test scenario, ZTE achieved an ultra-low latency of 0.416 ms based on a unified test platform, lower than the ITU-defined 1 ms. The system is based on ZTE’s self-developed chipsets, which is self-adaptable in eMBB and uRLLC scenarios. The results show ZTE’s leadership in the implementation of key 5G uRLLC technologies and prototypes, which is a key step for 5G commercialization in the future.
ZTE is committed to driving the commercialization of 5G products, laying a solid foundation for commercial 5G deployment in China by 2020.
