Provided is a system and method for configuring a multi-hierarchical cell in which a large-scale mobile backhaul technology and a small cell technology are combined. A mobile backhaul may increase a transmission capacity of a wireless backhaul using a super high frequency (SHF)/extremely high frequency (EHF) band, rather than a cellular band having a limitation in extending frequency resources, and a small group cell to be formed at a final end of the mobile backhaul may be configured by fixed group cells or mobile group cells depending on a radio environment, using a moving relay, wireless fidelity (WiFi), femto-cells, and the like, whereby cells may be miniaturized effectively, and a relatively great capacity of a wireless system may be provided to a subscriber.
