30 April 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 in partnership with China Unicom, ZTE has implemented the industry’s first Tri-RAT dynamic spectrum sharing solution,  SuperDSS, in the live network of the Henan Branch of China Unicom. realizing fast 5G deployments and simultaneously guaranteeing 3G services. 
The average throughput of SuperDSS in the same bandwidth has increased by 35% compared with that of LTE/NR DSS. SuperDSS can maintain 3G voice experience while greatly improving spectrum utilization efficiency. Therefore, SuperDSS offers an ideal solution to those operators who are eager to roll out 5G with limited spectrum resources. 
SuperDSS empowers the quick 5G roll-out while offering smooth transition of legacy voice service, thereby enabling 2G or 3G, 4G and 5G triple RAT dynamic sharing over the same spectrum with flexible and efficient scheduling capability. 2G or 3G bandwidth can be adjusted in accordance with service requirements, so that more bandwidth can be used for LTE and NR sharing while improving LTE and NR user throughput. 
Taking 20MHz bandwidth for example, in order to provide the 2G/3G service, at least one GSM frequency or UMTS carrier will be reserved, so the LTE/NR DSS can only be performed in 15MHz bandwidth, which is not optimal for spectrum utilization. However,  by means of SuperDSS, 2G or 3G, 4G and 5G can share all of the 20MHz bandwidth dynamically based on service requirement, so as to maximize spectrum utilization.
SuperDSS is a 5G-oriented innovation based on ZTE’s unique spectrum sharing solution, Magic Radio Pro. In the Henan branch of China Unicom, the sites empowered by ZTE’s  Magic Radio Pro solution have been more than 10,000 and will further increase in the 5G evolution.
Underpinned by the industry’s most comprehensive multi-RAT dynamic spectrum sharing solution, Magic Radio Pro, ZTE can support multiple inter-RAT sharing scenarios, including GSM/LTE, UMTS/LTE, GSM/UMTS, LTE/NR, UMTS/LTE/NR, GSM/LTE/NR, by means of five radio technologies of GSM, UMTS, LTE, NB-IoT and NR.   
ZTE has been committed to the innovation of spectrum sharing since 2014. By virtue of its valuable experiences in commercial deployment of dynamic spectrum sharing, ZTE will continue to help operators explore new possibilities and flexibility in 5G and network migration, thereby supporting global operators to address the challenges of 5G evolution.
ZTE is a provider of advanced telecommunications systems, mobile devices and enterprise technology solutions to consumers, operators, companies and public sector customers. As a part of ZTE’s strategy, the company is 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.
To date, ZTE has obtained 46 commercial 5G contracts in major markets, such as Europe, Asia Pacific, Middle East and Africa (MEA). ZTE commits 10 percent of its annual revenues to research and development and takes leadership roles in international standard development organizations.
