摘要	In cloud radio access network (Cloud-RAN), dense remote radio heads (RRHs) connect to baseband unit (BBU) pool through optical transport link, causing significant interference and power consumption in multicast downlinks. Coordinated beamforming with RRHs clustering is expected to be a key element towards improving network performance with more consideration of energy efficiency and interference management. This letter proposes an energy-aware joint clustering and scheduling (EA-JCS) scheme for multicast beamforming in Cloud-RAN downlink, which is formulated as a network utility maximization problem with fractional formulation and low-rank constraints. To efficiently solve this problem, we first develop a heuristic algorithm to provide sub-optimal performance by Dinkelbach's transformation. To handle non-convex formulation, we propose an iterative approximation algorithm with linear approximation and constraints relaxation. The effectiveness of the proposed scheme is confirmed by simulations.
