Future wireless communication systems are expected to provide more stable and higher data rate transmissions in the whole network. Recent research shows that it is advantageous to use relay stations in wireless networks in order to satisfy that need. But due to the limited power supply of mobile users, it may be difficult for the users to act as relays. Thus placing additional fixed relay stations to assist the communications is an attractive way for the cellular network solution. We present an overview of the state of the art for relaying networks, focusing on cellular relaying networks. Furthermore, we discuss in this paper the open issues to be solved in the future.
