ZTE completes the validation of the industry’s first 5G carrier aggregation on 700 MHz and 4.9 GHz
近日，中兴通讯在深圳率先完成了700MHz和4.9GHz频谱的5G载波聚合验证，进一步丰富了700MHz+4.9GHz双频组网解决方案，全面助力下一步全球700MHz频段5G商用建设。
13 May 2020, Shenzhen, China - ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, today announced that it has taken the lead in validating 5G carrier aggregation on 700 MHz and 4.9 GHz frequency bands in Shenzhen, China. This validation has further enriched the 700 MHz + 4.9 GHz dual-band networking solution, fully facilitating the next phase of commercial construction on 700 MHz.
Underpinned with ZTE's commercial 5G wireless base station and the latest 5GC core network equipment, this validation has employed ZTE's latest 5G test terminal system to achieve a system downlink data throughput up to 1.68Gbps.
本次演示基于中兴通讯商用5G无线基站和最新的5GC核心网设备，采用中兴通讯最新的5G测试终端系统，实现了700MHz +4.9GHz 双载波聚合展示，系统下行数据吞吐率达到1.68Gbps。
By effectively aggregating the dual-carrier resources at different frequencies on 700 MHz and 4.9 GHz, the service support capability of the dual-band networking solution is superior to that of 5G NR 100 MHz, thereby addressing the service competition problem of the future commercial use on 700 MHz.
ZTE is a provider of advanced telecommunications systems, mobile devices and enterprise technology solutions to consumers, operators, companies and public sector customers. The company has been committed to providing customers with integrated end-to-end innovations to deliver excellence and value as the telecommunications and information technology sectors converge. Listed in the stock exchanges of Hong Kong and Shenzhen (H share stock code: 0763.HK / A share stock code: 000063.SZ), ZTE sells its products and services in more than 160 countries.

5G相对于4G最大的优势是大带宽、低时延、高容量，国内外运营商当前5G网络建设多以2.6GHz/3.5GHz为主，大部分起步载波带宽一般为100MHz，单UE峰值超过1Gbps。700MHz频段做为最优质的黄金频谱，近年来获得全球各国政府的大力支持，包括中国在内的一些国家开始逐步规划和分配700MHz频谱给5G使用。由于700MHz频谱资源有限，能够分配的载波带宽资源最大20/30/40MHz左右，单UE峰值和系统容量方面相较2.6GHz/3.5GHz的100MHz载波略显不足，在支持一些类似AR/VR、高清视频等大带宽业务时系统容量压力较大。700MHz和4.9GHz频段载波聚合通过把不同频点的双载波资源有效聚合，实现超过常规5GNR 100MHz载波的业务支持能力，能够很好得解决未来700M商用面临的业务竞争难题。
作为全球领先的无线通讯解决方案供应商，中兴通讯近年来持续推动5G技术研究和产品开发，稳居商用第一梯队。本次700MHz+4.9GHz载波聚合演示将进一步丰700Mhz解决方案，助力全球700MHz 5G商用。
