COMMUNICATION SYSTEM
The present invention has an object to provide a communication system of 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 in a portion surrounded by a solid line 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.
1 . A communication system comprising a movable terminal device and a plurality of communication devices configured to perform radio communication with said terminal device, wherein
said plurality of communication devices include a large-scale communication device having a relatively large range in which communication with said terminal device is possible and a small-scale communication device having a relatively small range in which said communication is possible,
said terminal device is prohibited from a handover from said large-scale communication device to said small-scale communication device (a) when said small-scale communication device is connected with said large-scale communication device by a dedicated line, (b) when said small-scale communication device shares functionality of said large-scale communication device, or (c) when said small-scale communication device is located within a range of said large-scale communication device, communicable with said terminal device.
