本文通过6-18 GHz城市宏小区测量，揭示路径损耗随频率增加而增加、时延扩展减小，并量化了同站覆盖距离随频率下降的趋势，为6G上中频段部署提供依据。
AI 中文摘要
6-18 GHz的上中频段因其在可用带宽和传播能力之间的有利平衡，被认为是未来第六代（6G）网络有前景的频谱范围，而其同站覆盖性能仍是一个关键的部署问题。本文在城市宏小区（UMa）环境中，在从6到18 GHz的13个空间对齐的频率点上进行了宽带信道测量活动，并研究了信道特性的频率演变和同站覆盖能力。结果表明，路径损耗通常随频率增加而增加，而较高频率的信道往往表现出较小的均方根（RMS）时延扩展（DS）和较大的基于PDP的K因子。基于测量的路径损耗特性，进一步评估了额外的链路预算要求和业务感知的同站覆盖。在基准业务配置下，80%覆盖距离d80从6 GHz时的大约129米减小到18 GHz时的58米。进一步的分析量化了业务速率、资源分配、干扰和链路预算下降对覆盖的影响，为6-18 GHz频段的同站部署提供了基于测量的见解。
英文摘要
The 6--18~GHz upper mid-band is a promising spectrum range for future sixth-generation (6G) networks due to its favorable balance between available bandwidth and propagation capability, while its same-site coverage performance remains a key deployment concern. This paper presents a wideband channel measurement campaign at 13 spatially aligned frequency points from 6 to 18~GHz in an urban macrocell (UMa) environment, and investigates the frequency evolution of channel characteristics and same-site coverage capability. The results show that path loss generally increases with frequency, while the higher-frequency channels tend to exhibit smaller root-mean-square (RMS) delay spread (DS) and larger PDP-based $K$-factors. Based on the measured path-loss characteristics, the additional link-budget requirement and service-aware same-site coverage are further evaluated. Under the baseline service configuration, the 80\% coverage distance $d_{80}$ decreases from approximately 129~m at 6~GHz to 58~m at 18~GHz. Further analysis quantifies the impacts of service rate, resource allocation, interference, and link-budget degradation on coverage, providing measurement-based insights for same-site deployment across the 6--18~GHz band.
