In a transmission device on a serving eNB side, a first packet transmission unit performs an operation of transmitting a retransmission data packet. On the other hand, in a transmission device on a collaborative eNB side, a second packet transmission unit performs an operation of transmitting a new data packet corresponding to information transferred from the serving eNB by the packet transfer unit. The control information about a communication to a UE by the serving eNB and the collaborative eNB is communicated by using only a PUCCH from the UE to the serving eNB and a PDCCH from the serving eNB to the UE. The serving eNB and the collaborative eNB perform communications of a new data packet and communication control information etc. through an X2 interface. |
