CTOnews.com, November 3, recently, under the unified guidance of China Radio and Television Group, Ziguang Zhareui, together with ZTE and other companies, have fully realized 5G NR broadcasting based on the 3GPP R17 standard, which means that mobile phones equipped with Ziguang Zhanrui 5G chip will be able to receive 5G broadcasts in the future.

According to Ziguang Zhanrui, Ziguang Zhanrui participated in the industry's first full industrial chain-including the 5G NR broadcast 700MHz band end-to-end business network jointly constructed by China Radio and Television Group, ZTE core network and wireless access network, and Ziguang Zhanrui mobile phone reference prototype. The content covers many functions, such as basic broadcasting service, broadcast and unicast concurrence, card-less broadcast reception, emergency broadcasting and so on. The final result is in line with the 3GPP standard protocol process and performance expectations.

CTOnews.com Note: 5G NR broadcast technology (also known as 5G NR MBS multicast broadcast technology) is an important functional feature of 3GPP R17 version 5G international standard. It is mainly aimed at public security, IoT applications, software delivery, TV Video, IPTV, hot spot live broadcasting and other scenarios. For example, when an emergency occurs, a large number of users in a specific location can receive early warning or notification at the same time.

This technology combines radio and television with 5G communication, and combines television with mobile phone screens. The 5G NR broadcast based on R17 and the 5G mobile network adopt a unified system architecture and reuse key technologies, protocol processes and spectrum resources.

The 700MHz 5G NR broadcasting technology led by China Radio and Television has been supported by 3GPP and ITU International Standards Organization. In the actual combat scenes such as emergency broadcasting and Winter Olympic Games, it has launched traffic-free, multi-station live broadcast and VR / XR virtual reality immersive viewing services.

At present, 5G NR radio and television trials have been carried out in China, Switzerland, France, Germany, Italy, Austria, Denmark, Spain and other countries.
