In this paper, the planning problem of multiple evolved Node Bs (eNBs) and two types of relay nodes is defined base on linear programming. Type 1 relay nodes are placed in the center of eNB, and Type 1a relay nodes are deployed at cell edge. Three algorithms are proposed to investigate the Type 1a relay node placement and communication interference. All algorithms are designed on the basis of graph theory and analyzed in planning case and simulation results. The ultimate goal is to maximize the average throughput of all served users with minimum communication interference. Results showed that the proposed interference coordination algorithm not only provides the lowest construction cost with slightly fewer numbers of served users but also eliminates the communication interference with the highest average throughput. Most importantly, it achieves the best communication quality for next generation mobile networks.
