摘要
A digital communication system including a terminal and a plurality of base stations. The terminal includes receiving of a first control channel which is transmitted only from the first base station, the received first control channel is configured to indicate resource assignment for both data transmitted from the first base station and data coordinately transmitted from the second base station, and is configured to indicate new data or retransmission data. The terminal a second control channel including first control information and second control information only to the first base station. The first control information is channel state information, and the second control information is Hybrid Automatic Repeat reQuest (HARQ) acknowledgement information for the received data coordinately transmitted. The second control information is based on a result of the HARQ process of the received data coordinately transmitted, and the second control channel is transmitted only to the first base station.

By comparing the link (link 1) from the coordinated eNB to the UE with the link (link 2) from the serving eNB to the UE, some observation results are obtained as follows.
-
- When a retransmission data packet is delivered from the serving eNB, the SINR gain for the link 1 in the SIC process is about 2 through 2.5 dB.
- When the retransmission data packet is delivered from the coordinated eNB, the SINR gain for the link 2 in the SIC process is about 1.5 through 1.75 dB.
- When the value of Δ increases, the SINR gain of the link 1 becomes larger, and the SINR gain of the link 2 becomes smaller. Thus, it is preferable that the value of Δ is not too small or large. In addition, a small value of Δ causes a too small possibility of a coordinated transmission, and a large value of Δ causes a too large possibility of a coordinated transmission. An appropriate value of Δ is between 8 dB and 10 dB. As a conclusion based on the study of the SINR gain by the SIC, the retransmission data packet is to be delivered constantly from the serving eNB.
