Abstract: First, the background of 5G broadcasting is introduced. The historical evolution of broadcasting, in conjunction with 3GPP, is then discussed. Subsequently, two future technical routes of 5G broadcasting, namely terrestrial broadcasting and hybrid broadcasting, are presented. Finally, the opportunities and challenges of 5G broadcasting are explored and summarized.
Keywords:5G broadcasting; technological evolution; hybrid model; dual network coordination
