Requirements: 5G KPIs as a “Flower of 5G“

5G typical performance:

Gbit, 1ms, 1 million/km2

Defined 5G KPIs as a“Flower of 5G”: Released the white paper “5G Vision and Requirements" by IMT-2020(5G)

Driving the standardization work of 5G requirements

Led the requirement projects within IMT-2020 (5G), ITU, NGMN

China Mobile was rapprteur of the 3GPP "5G scenario and needs" project

CMCC has been driving 5G requirements standardization, resulted in 8 5G KPIs described as a “Flower of 5G”and adopted by ITU
