摘要:

本文针对室内热点(InH)场景,基于NYU WIRELESS在6.75 GHz、16.95 GHz、28 GHz、73 GHz和142 GHz频率下使用1 GHz宽带时域滑动相关信道探测器在视距(LOS)和非视距(NLOS)信道条件下进行的广泛实测数据,全面推导了特定频率以及7-24 GHz、0.5-100 GHz和0.5-150 GHz频率范围内的单频和多频大尺度路径损耗模型参数,涵盖近距离(CI)自由空间参考距离模型、带交叉极化的CI自由空间参考距离(CIX)模型、浮动截距(FI)模型、带频率相关路径损耗指数的CI自由空间参考距离(CIF)模型、带频率相关路径损耗指数和交叉极化的CI自由空间参考距离(CIFX)模型、α-β-γ(ABG)模型以及带交叉极化的α-β-γ(ABGX)模型。具体而言,本文推导的7-24 GHz和0.5-100 GHz频段的CI、FI和ABG路径损耗模型参数已提交至第三代合作伙伴计划(3GPP),用于验证技术报告(TR)38.901 InH路径损耗模型,作为版本(Rel)19中“7-24 GHz TR 38.901信道模型验证”研究的一部分。此外,本文结果为理解大尺度路径损耗、比较不同路径损耗模型以及扩展3GPP和ITU为InH场景标准化的路径损耗模型提供了关键见解,这对于推进下一代无线系统至关重要。

英文摘要:

This paper presents a comprehensive derivation of single and multi-frequency large-scale path loss model parameters for the close-in (CI) free space reference distance, CI free space reference distance with cross-polarization (CIX), floating-intercept (FI), CI free space reference distance with frequency-dependent path loss exponent (CIF), CI free space reference distance with frequency-dependent path loss exponent and cross-polarization (CIFX), alpha-beta-gamma (ABG), and alpha-beta-gamma with cross-polarization (ABGX) models for specific frequencies and across frequency ranges of 7-24 GHz, 0.5-100 GHz, and 0.5-150 GHz. The analysis is based on extensive real-world measurements conducted by NYU WIRELESS at 6.75 GHz, 16.95 GHz, 28 GHz, 73 GHz, and 142 GHz, using a 1 GHz wideband time-domain based sliding correlation channel sounder in the indoor hotspot (InH) scenario in both line-of-sight (LOS) and non-line-of-sight (NLOS) channel conditions. Specifically, the derived CI, FI, and ABG path loss model parameters for 7-24 GHz and 0.5-100 GHz frequency ranges in this article were submitted in Third Generation Partnership Project (3GPP) to validate Technical Report (TR) 38.901 InH path loss models, as part of the release (Rel) 19 study on "Channel Model Validation of TR 38.901 for 7-24 GHz." Furthermore, the results in this paper provide critical insights into understanding large-scale path loss, comparing different path loss models, and extending the path loss models standardized by 3GPP and ITU for the InH scenario, which is essential for advancing next-generation wireless systems.
