| Abstract(in English) | This paper presents an adaptive amplify-and-forward (AF)-type relaying method with fractional frequency reuse (FFR) for the multiuser cellular uplink. The adaptive AF relaying method adaptively selects the active relay stations (RSs) based on the path loss between each mobile terminal and the base station (BS) and that between each RS in order to mitigate the enhancement of inter-cell interference due to the AF-type relaying. Meanwhile, the FFR restricts the assigned bandwidth for the cell-edge terminal so that the amount of the average inter-cell interference is reduced. However, the fractional frequency reuse reduces the multiuser diversity gain when the proportional fair (PF) scheduling is used. The computer simulations show that although the FFR is effective in the cell-edge user throughput enhancement for the case without relaying or the conventional AF relaying, it is not effective for the proposed adaptive AF relaying since the proposed method can solely increase the received signal power of cell-edge users without significant increase in inter-cell interference. It is shown that the combination of the adaptive AF relaying and one cell frequency reuse is superior to the combination of the FFR and no relay or conventional AF relaying from the viewpoint of average user and cell-edge user throughputs. |
