Scheduling and adaptive resource allocation on ICIC with testbed implementation

Inter-Cell Interference Coordination (ICIC) is introduced to mitigate interference at cell-edge User Equipments (UE). A variety of ICIC approaches were proposed in previous literature. However, most of them focused only on resource allocation methods, which were not practical enough for implementation. In our ICIC design, we propose not only a resource allocation scheme but also a scheduling method. The proposed resource optimizer can find an ICIC solution efficiently. The proposed scheduler can maintain the performance of the solution in each Transmission Time Interval (TTI). Both of the resource optimizer and the scheduler are compatible with the testbed. Simulation results shows our proposed schemes outperformed other literature findings in edge throughput and edge UE fairness. Testbed results also shows real gain and the feasibility of our algorithms.
