论文摘要
上行链路（UL）/下行链路（DL）解耦访问已成为一种新颖的访问体系结构，以提高蜂窝网络的性能提高。在本文中，我们研究了蜂窝车到所有物品（C-V2X）中的UL/DL脱钩访问性能。我们从光谱效率的角度（SE）提出了C-V2X中UL/DL脱钩访问的统一分析框架。通过对UL/DL解耦访问C-V2X作为COX过程并利用随机几何形状进行建模，我们获得了关节关联概率，对服务基站的UL/DL距离分布以及在具有不同关联案例的C-V2X网络中的UL/DL解耦访问。我们进行了广泛的蒙特卡洛模拟，以验证拟议的统一分析框架的准确性，结果显示C-V2X中UL/DL解耦访问的系统平均SE更好。
The uplink (UL)/downlink (DL) decoupled access has been emerging as a novel access architecture to improve the performance gains in cellular networks. In this paper, we investigate the UL/DL decoupled access performance in cellular vehicle-to-everything (C-V2X). We propose a unified analytical framework for the UL/DL decoupled access in C-V2X from the perspective of spectral efficiency (SE). By modeling the UL/DL decoupled access C-V2X as a Cox process and leveraging the stochastic geometry, we obtain the joint association probability, the UL/DL distance distributions to serving base stations and the SE for the UL/DL decoupled access in C-V2X networks with different association cases. We conduct extensive Monte Carlo simulations to verify the accuracy of the proposed unified analytical framework, and the results show a better system average SE of UL/DL decoupled access in C-V2X.
