During the network planning process, it is very important to identify the key network design factors and define how to take them into account to achieve optimally performing networks. The introduction of Relay Stations (RSs) in OFDMA-based networks will bring numerous advantages such as coverage extension and capacity enhancement due to the deployment of new cells and the reduction of distance between transmitter and receiver. However, the use of RSs will also bring new challenges to the network designers, for example, interference management in multihop communications. This work establishes the fundamentals of a new approach that will adapt the tilt, azimuth, and frequency assignment in OFDMA networks - in the form of subchannel planning - according to the changing conditions of the traffic and the radio channel in a novel two-step process for network design. An example of deployment is presented in this paper.
