摘要
Following the massive commercialization of 5G mobile communication systems,both academia and industry are initiating research activities to shape the next-generation communication systems,namely,6G.Although the detailed killer-applications and key technologies of 6G have not been clearly defined yet,it is commonly expected that 6G will provide hyper-coverage and hyper-connectivity.Enabled by these capabilities,the 6G communication systems are especially aiming at improving the user’s experience greatly,or more ambitiously,to change the way of human’s everyday life.So far,many new services with more stringent requirements,such as truly immersive extended reality(XR),high-fidelity mobile hologram,and digital replica,are expected to be satisfied by the 6G communication systems.
