摘要

2.1 GHz频段重耕是城区5G网络部署需要研究的重要课题。分析了仿真预测网络覆盖存在的缺陷。考虑绝大部分5G基站与LTE同址并采用相同或相似工参的情况，提出了基于LTE 测量报告的2.1 GHz和3.5 GHz 5G SA覆盖评估方法。该方法首先建立同址2.1 GHz和3.5 GHz 5G SA覆盖差异模型并通过测试验证其准确性，然后根据LTE测量报告、覆盖差异模型及速率与链路损耗关系评估两个频段的覆盖质量。评估实例表明，因城区LTE网络覆盖具有10 dB余量，同址20 MHz带宽内的2.1 GHz 5G重耕仅在1～10 Mbit/s上行速率覆盖率较3.5 GHz有1.3～5.2个百分点的增益。

Abstract

2.1 GHz refarming is a key issue for the evolution of 5G network.Limitations of network simulation were analyzed.Since most of 5G sites were co-sited with LTE and adopted the same or similar engineering parameters

an approach of 2.1 GHz and 3.5 GHz 5G SA network coverage evaluation was proposed.A co-site coverage differential model between 2.1 GHz and 3.5 GHz 5G SA was given and its accuracy was verified by field trial.Then the coverage of two frequencies were predicted based on LTE MR

the differential model and the uplink rate curve relative to link loss.The evaluation instance indicates only 1.3～5.2 pp coverage gain is achieved at uplink rate between 1 Mbit/s and 10 Mbit/s by refarming 2.1 GHz within 20 MHz bandwidth

because of the 10 dB margin of LTE coverage.
