VLC-WIFI heterogeneous networks have become a promising solution, where VLC and WIFI are collaborating on providing services for indoor users. The dense deployment of visible light communication multiple access points (APs) can expand the system capacity, but it leads to complicated inter-cell interference (ICI). In order to arrange users to access the appropriate AP and implement interference management, a novel scheme called user-centric access based on regular spectrum allocation (UCARSA) is proposed in the paper. In UCARSA, the sliced visible spectrum is assigned to VLC APs regularly, so that the user associated with more than one AP is impacted less by ICI. Furthermore, the virtual community is constructed for each user to balance the user rate and improve the average spectral efficiency. The above performance improvement can be proved by simulation results in this paper, and it shows that the performance of UCARSA is better than two kinds of comparison algorithms.

基于干扰管理的室内VLC-WIFI异构网络以用户为中心的接入方案

VLC-WIFI异构网络已经成为一种很有前景的解决方案，VLC和WIFI正在合作为室内用户提供服务。可见光通信多接入点（AP）的密集部署可以扩展系统容量，但会导致复杂的小区间干扰（ICI）。为了安排用户接入合适的AP并实现干扰管理，本文提出了一种新的基于规则频谱分配的以用户为中心的接入方案(UCARA)。在 UCARSA 中，切片的可见光谱被定期分配给 VLC AP，这样与多个 AP 关联的用户受 ICI 的影响较小。此外，为每个用户构建虚拟社区以平衡用户速率并提高平均频谱效率。
