英文摘要	A novel picocell cite selection scheme in heterogeneous networks (HetNet) is proposed in this paper. Unlike traditional deployment of picocells, we consider the scenario with picocells at the edge instead of under the umbrella of macrocells in HetNet. In the novel scheme, one picocell eNodeB (PeNB) with directional antennas is deployed on the border of neighbor macrocells which is equivalent to a combiner of PeNBs to associate MeNBs around. Compared with the traditional scheme, we have proved that the novel picocell cite selection performs better in both fairness and efficiency, in terms of coverage area, offload rate, and field strength for both edge users and overall users in picocells with fixed system parameters. Meanwhile, performance gains provided by novel picocell site selection is also derived with range expansion consideration. Our results show that, compared with the traditional scheme, more than 0.6944% macrocell users are offloaded to picocell in the novel scheme and the offload rate is enhanced by 98.4%. Furthermore, the field strength improved by the novel scheme is twice as much as the traditional scheme.; Automation & Control Systems; Engineering, Electrical & Electronic; Engineering, Mechanical; EI; CPCI-S(ISTP); 0
