Currently, eMBB, mMTC and URLLC defined by 5G cannot support more diverse IoT scenarios. Therefore, he proposed three new scenarios for enrichment and enrichment. One is UCBC, which focuses on the construction of uplink capabilities; the other is RTBC, which has three characteristics of ultra-wideband, low latency and high reliability; and the third is HCS, which focuses on communication and perception fusion. Capacity building. Three old scenarios plus three new scenarios together constitute a 5.5G scenario. Finally, he concluded: "From supporting the Internet of Everything to enabling the intelligent connection of everything, this is the core content of the 5.5G vision."
