6G Repeaters for Non-Terrestrial Network

This paper investigates required features for repeaters to enable robust and stable 6G non-terrestrial networks with various types of transceivers from hand-held user equipment to satellite. In this paper, we show that the 5G repeater cannot fully cover the 6G non-terrestrial network operation scenarios due to its stationary nature, optimized for the legacy terrestrial networks. By introducing new repeater features as suggested in this paper, it is expected that the 6G repeater will provide seamless connectivity as backhauls and fronthauls for NTN in near future.
