Abstract:Characterizing user access methods in heterogeneous cloud radio access networks (H-CRANs) is critical for performance optimization. Different from the user access in cloud radio access networks (C-RANs), the inter-tier interference from macro base station has a great impact on user access in H-CRANs. In this paper, after considering the inter-tier interference, the ergodic rates of downlink H-CRANs for two proposed user access methods, namely distance based and cluster based, are analyzed. The corresponding ma… Show more
