5G radio access networks achieve large communication capacity with small control signal overheads by combining low frequency bands in macro cells with high frequency bands in small add-on cells. This paper addresses the challenges and solutions for 5G group mobility where rapidly moving platforms carry several different user devices. Entrance capacity and control signal load are also studied by link level and system level evaluations to verify the effectiveness of moving cell, an attractive possible solution.
