摘　　要：基于3GPP-TR 38.901 V18.(Release 18,2024年3月发布),结合高铁道路5G无线覆盖场景实际情况,考虑空间距离、视距情况等因素,文中重点探究了5G郊区场景宏站传播损耗模型特点。此外,进一步将高铁道路无线覆盖场景细化分类为无遮挡场景、路堑场景、山丘场景、高架场景,分析了与3GPP的匹配情况。从视距和非视距角度来看,结合MATLAB仿真结果,总结了其局限性,并提出了进一步研究信道模型的必要性。Based on 3GPP TR 38.901 V18.(Release 18,released in March 2024),combined with the actual situation of 5G wireless coverage on high-speed rail roads,and considering factors such as spatial distance and line of sight,this paper focuses on exploring the characteristics of the 5G suburban scenario macro station propagation loss model.In addition,the wireless coverage scenarios of high-speed rail roads were further refined and classified into unobstructed scenarios,road cutting scenarios,hill scenarios,and elevated scenarios,and the matching situation with 3GPP was analyzed.From the perspectives of line of sight and non line of sight,combined with MATLAB simulation results,the limitations were summarized,and the necessity of further studying channel models was proposed.
