Device-to-device (D2D) communications underlaying cellular networks enhance system capacity and bandwidth utilization. In this approach, secondary users (D2D devices) share the radio resources allocated to primary users (cellular UE), achieving increased system capacity and spectrum efficiency. However, the allocation of inappropriate resources and transmission power to devices introduces excessive co-channel interference, which could impair primary user communication. The proposed research addresses this challenge by developing a Multi-Value Bipartite Matching (MBM) Algorithm that jointly allocates resources and transmission power for both primary and secondary users maintaining individual data rate constraints. Numerical analyses show that this approach outperforms existing algorithms in determining appropriate power levels while meeting specified constraints, ultimately improving system capacity and reducing interference. |
