In this paper, we propose an interference coordination scheme by an innovative combination of soft frequency reuse (SFR) and cooperative multipoint transmission (CoMP) to manage both co- tier and cross-tier interference in a randomly deployed macro-pico network modeled by Poisson Point Process (PPP). The proposed scheme is performed in three stages. First, the frequency reuse pattern of SFR for macrocells is determined based on the interference graph that describes interference relationship between macrocells. Second, the frequency reuse pattern of SFR for each picocell mainly depends on the measurement exchanged with its surrounding cells. Third, the CoMP scheme is performed on the secondary bands of macrocells to enhance the performance of Picocell-edge users and ensure fairness between various users. A scaling factor is considered to protect the data rates of macro cell-center users. In addition, the cross- component carrier (Cross-CC) proportional fair (PF) scheduling is adopted for the detailed resource block (RB) allocation in the carrier aggregation (CA) supported system to achieve the maximum of system fairness. Numerical results show that the proposed scheme can effectively improve cell-edge user data rate and ensure the fairness between users when compared with the SFR scheme and the full frequency reuse (Reuse 1) scheme.
