Mobile-broadband traffic has experienced a large increase and the network has continuously expanded over the past few years. Pico cells are envisioned to cope with such a demand of capacity in network environments. Since those small cells are low-cost nodes, a thorough deployment is not typically performed, particularly in LTE-A Het Nets. As a result, the matching between traffic demand and network...
Joint optimization of user association, resource allocation and Almost Blank Subframe (ABSF) based enhanced Inter-Cell Interference Coordination (eICIC), on which macro-cells mute for scheduling the pico users, is of great importance to further improve the network performance in HetNets, however, the introduce of ABSF makes analyzing resource allocation extremely difficult because this results in...
