Quality of Experience-aware enhanced Inter-Cell Interference Cordination for Self Organized HetNet

In fifth-generation (5G) mobile networks, a major challenge is to face with the dramatic data increase due to the generalized demands of mobile consumers for Full High Definition/High Definition (Full HD/HD) videos. One promising technology to solve this problem is heterogeneous networks (HetNets), which involve the deployment of large number of densified low power cells. However, in heterogeneous cellular networks, coordination of cell scheduling is required to efficiently distribute the resources and mitigate inter-cell interference. To solve this issue, a new approach based on game theory and optimizing cell time transmission muting and transmission and user attachment is proposed. The method directly involves Quality of Experience (QoE) in maximization of an overall video utility instead network utility, aiming at driving inter-cell interference coordination algorithms with user satisfaction. The proposed solution is compared with a state-of-the-art strategy, and the numerical results show that how QoE awareness significantly improves the efficiency of interference management for the benefit of density of user requesting higher quality videos.
