D2D通信是5G/B5G网络的关键技术之一,同时小小区的中心化部署形成了以父点为中心的簇.因此,文章构建了一个基于泊松点和泊松簇过程的网络模型,提出了一种基于簇的用户设备(User Equipment
UE)分类方案,并设计了联合正交与共享的频谱资源分配方案.基于簇的UEs分类方案将UEs分为不同类型的簇中心和簇边缘UEs;联合频谱分配方案,将可获得的频带分为正交的两个子带,不同类型的UEs (BSs)共享子带.对此设计,建立了D2D接收机的干扰模型,给出了干扰分布,并分析了簇中心和簇边缘D2D接收机的覆盖概率.仿真和数值结果表明D2D网络覆盖概率随着微微BS (Pico BS
PBS)发射功率的减小而增加.同时,也给出了PBS 覆盖半径和D2D发射机覆盖半径对D2D网络覆盖概率的影响.
D2D communication is one of the key technologies of 5G/B5G networks. Meanwhile
in 5G/B5G network
the centralized deployment of small base stations (BSs) makes user equipment (UE) located inside or outside the cluster. This paper constructs a network model based on Poisson point and Poisson cluster processes
and proposes a cluster‑based UEs classification scheme as well as a spectrum resource allocation scheme by joining orthogonal and sharing methods. The cluster‑based UEs classification scheme divides UEs into different types of cluster center and cluster edge UEs. The joint spectrum allocation scheme divides the available frequency band into two orthogonal sub‑bands
which are allocated to different types of UEs (BSs). For this design
this paper establishes a D2D receiver interference model
gives the interference distribution
and analyzes the coverage probability of the cluster center and cluster edge D2D receivers. Simulation and numerical results show that the D2D network coverage probability increases as the transmit power of pico BS (PBS) decreases. Meanwhile
the influence of the coverage radius of PBS and D2D transmitters on the coverage probability of the D2D network is also given.
