摘要

In this letter, a framework to optimize device association (DA), radio resource allocation (RA), and power allocation (PA) in heterogeneous cloud radio access network (H-CRAN) is proposed. In H-CRAN, small remote radio heads (SRRHs) are deployed underlaying the macro remote radio head (MRRH) to serve a group of SRRH devices (SDVs) by reusing the same radio resources allocated to MRRH devices (MDVs). The DA, RA, and PA optimization process is designed to maximize the network sum-rate while guaranteeing the rate requirements for SDVs, fronthaul capacity constraints, and MDVs interference protection. For DA and RA, an approach dependent on matching game is proposed to model the interactions between devices and SRRHs. In addition, Lagrangian dual decomposition is adopted to determine the optimum power allocation for each radio resource. Simulation results validate the superiority of the proposed algorithm compared with other schemes.
