A communication system improving the communication quality in a case where a plurality of communication devices having different sizes of ranges coexist, in which communication with a terminal device is possible, to thereby improve an entire throughput. In a case where a remote radio head (RRH) is installed in a coverage of a macro cell, an uplink resource transmitted from a user equipment (UE) to the macro cell, that is, an uplink carrier frequency band UL1 of the macro cell is received not only by the macro cell but also by the RRH. Then, the macro cell combines a reception signal regarding the uplink resource of the macro cell, which has been received by the macro cell, and a reception signal regarding the uplink resource of the macro cell, which has been received by the RRH.
