The base station of new system covers its service area with spot beams formed by many beamforming antennas, and one beam can be composed of multiple frequency allocation beam component carriers in which one broadband bandwidth is divided into multiple sub-bands at the millimeter frequency. The best feature of new cellular architecture is the multi-layered FA dynamic cell configuration and it means that one or more beam component carrier(s) can be grouped and then operated as one cell. The effect of this dynamic cell configuration is to avoid interference among cells via the association among multi-layered FAs and to imitate pseudo-small cells and pseudo-macro cell like 3GPP small cell enhancement architecture (user equipment in small cell enhancement architecture can use coverage layer (macro cell(s)) for mobility robustness and capacity layer (small cells) for capacity offering). In this paper, we design new system, its basic operation and evaluate its capacity to confirm the possibility as an alternative of 5G mobile communications.
