华为5G无线网络规划处理办法白皮书
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">5G网络在频谱、空口和网络架构上制订了跨代的全新标准，以满足<span style="color: black;">将来</span>的应用场景。而这些新标准、新技术，给5G无线网络规划<span style="color: black;">行业</span>带来了<span style="color: black;">非常多</span>挑战。为满足海量连接、超高速率<span style="color: black;">需要</span>，5G网络可用频谱除了Sub6G，还<span style="color: black;">包含</span>业界高度关注的28/39G等高频段。与低频无线传播特性相比，高频对无线传播路径上的建筑物材质、植被、雨衰/氧衰等更<span style="color: black;">敏锐</span>，<span style="color: black;">例如</span>经<span style="color: black;">科研</span>：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">LOS和NLOS场景下，高频相比低频，链路损耗将分别<span style="color: black;">增多</span>16~24dB和10~18dB；同一频段，NLOS场景相比LOS场景，链路损耗将<span style="color: black;">增多</span>15~30dB；High Loss和Low Loss场景下，高频相比低频，穿透损耗将分别<span style="color: black;">增多</span>10~18dB和5~10dB；</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">另外，<span style="color: black;">区别</span>频段存在<span style="color: black;">区别</span>的<span style="color: black;">运用</span>规则和约束，<span style="color: black;">包含</span>licensed、unlicensed、授权准入等，这使得频谱规划<span style="color: black;">亦</span>变得更加<span style="color: black;">繁杂</span>。综上所述，新频谱带来的挑战和新<span style="color: black;">科研</span>课题<span style="color: black;">包含</span>：</p>高频段的<span style="color: black;">基本</span>传播特性<span style="color: black;">科研</span>，构建高频的传播特性<span style="color: black;">基本</span>数据库和覆盖能力基线；传播模型<span style="color: black;">怎样</span>对千差万别的材质建模？<span style="color: black;">怎样</span>对基于高精度电子地图的场景<span style="color: black;">归类</span>？可应用在高、低频段的高准确性和<span style="color: black;">有效</span>率的射线<span style="color: black;">跟踪</span>模型；<span style="color: black;">怎样</span>支持<span style="color: black;">各样</span>类型可用频谱资源的智能频谱规划？<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">另一</span>，5G高频网络较小的覆盖范围对站址和工参规划的精度提出了更高的<span style="color: black;">需求</span>，采用高精度的3D场景建模和高精度的射线<span style="color: black;">跟踪</span>模型是<span style="color: black;">加强</span>规划准确性的技术方向，但这些技术<span style="color: black;">亦</span>会带来规划仿真效率、工程成本等方面的挑战。</p>
