摘　　要：可见光通信(VLC)和无线保真(WiFi)组网被认为是实现未来6G移动通信的关键技术之一。为了提高室内资源分配满足业务服务质量(QoS)需求的概率,该文提出一种基于干扰管理和服务质量(QoS)驱动的跨层资源分配机制(CRAMIMQ)。该机制能根据物理层的信道状态与媒体访问控制层的队列状态,设计下行VLC-WiFi传输链路的自适应QoS级别评估方法和信道质量管控方法;提出基于干扰管理和QoS驱动的跨层资源分配机制以满足业务的QoS需求。仿真结果显示,相比QoS感知的跨层动态资源分配(QoS-CLDRA)方法,所提CRAMIMQ提高了业务接入成功概率,进而使最大的系统吞吐量约提高5.64%,VLC缓冲队列长度减小21.8%。Visible Light Communication(VLC)and Wireless Fidelity(WiFi)network are considered one of the key technologies for future 6G mobile communication.So a Cross-layer Resource Allocation Mechanism based on Interference Management and QoS-driven(CRAMIMQ)is proposed to improve the probability that allocating resource can meet service’s quality of service(QoS)requirement.According to the channel state of the physical layer and the queue state of the media access control layer in VLC-WiFi network,an adaptive QoS level evaluation of VLC-WiFi transmission downlink and channel’s quality control method are designed in proposed CRAMIMQ.Then a cross layer resource allocation method based on interference management and QoS driven is put forward to meet the QoS requirements of service.Compared to the QoS-aware cross-layer dynamic resource allocation(QoS CLDRA)method,The simulation results show that proposed CRAMIMQ can improve the successful probability of service access,and achieve a maximum system throughput increase of 5.64%and a 21.8%reduction in VLC buffer queue length approximately.
