Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink (user equipment (UE) transmission) and a downlink (node B transmission) to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, high-altitude platform stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile nodes B and the like and enabling network operation optimization and automation and the like; an use of AI in wireless communication for improvement of overall network operation by considering AI from the initial phase of developing technologies for 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of UE computing ability through reachable super-high-performance communication and computing resources (MEC, clouds, and the like) over the network.
It is expected that such research and development of 6G communication systems will bring the next hyper-connected experience to every corner of life. Particularly, it is expected that services such as truly immersive XR, high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems.
