Abstract

In dynamic HeNB networks, each user-installed HeNB autonomously selects component carriers (CCs) depending on offered traffic and interference relations with other cells. But it will cause that certain HeNB can't select feasible CC. Due to that the performance of BIM based ACCS scheme are sensitive to the predefined BIM threshold, we first introduce an adaptive binary criterion to determine whether two HeNBs can use the same CC. Furthermore, we propose a cooperative component carrier reselection algorithm based on backup CC list, to control inter-cell interference (ICI) and enhance the possibility of successful carrier selection. Simulation results show that CCCS can enhance the system performance both in terms of average user throughput and user outage rate.
