Аннотация
Cloud radio access networks (C-RANs) have been regarded as a promising
architecture for energy-efficient fifth generation systems. In this paper,
a new joint remote radio head (RRH) activation, user-RRH pairing and
resource allocation strategy is proposed for heterogeneous C-RANs
(H-CRANs). We first formulate an optimization problem to maximize the
energy efficiency of H-CRANs. Then, a low-complexity suboptimal solution is
developed. Our proposed mechanism consists of three key procedures: 1) RRH
activation is performed based on greedy RRH selection; 2) user-RRH pairing
is performed based on the channel quality; 3) the resource allocation
problem is solved by dual decomposition. Simulation results show that the
proposed strategy can improve energy efficiency significantly.
