WIRELESS BASE STATION DEVICE USING COLLABORATIVE HARQ COMMUNICATION METHOD, WIRELESS TERMINAL DEVICE, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD

摘要

In a transmitter on a supplying eNB side, a first packet transmitting part carries out an operation of transmitting a retransmitted data packet. In a transmitter on a cooperative NB side, on the other hand, a second packet transmitting part carries out an operation of transmitting a novel data packet corresponding to information transferred from the supplying eNB by a packet transfer part. Control information of communication by the supplying eNB and the cooperative eNB to a UE is communicated only through a PUCCH extending from the UE to the supplying eNB and a PDCCH extending from the supplying eNB to the UE. The supplying eNB and the cooperative eNB communicate the novel data packet, the communication control information or the like through an X2 interface.
