An optimizing algorithm for interference coordination under LTE downlink

This article analyzes the performances of the current mainstream of interference coordination algorithm, describes the major functions of interference coordination algorithm, introduces the key indexes of the algorithm performance analysis, and presents an optimizing method - MSFR, based on the soft frequency reuse (SFR) algorithm. This article does theoretical analysis and simulation analysis on the performance of the interference coordination algorithm. The results show MSFR algorithm only has constraints on cell resources, can increase the chance of better channel in the system, has no constraints on scheduling algorithm, does not need to know user positions and is easy to implement.
