论文摘要
在计划在Sub-6GHz频段中计划5G网络时，可以应用与LTE相似的细胞计划技术。从澳大利亚环境中，N78频段（3.3-3.8GHz TDD）比现有LTE网络中使用的2.6GHz频段高约1GHz。结果，覆盖范围的占地面积可能相似，因此在现有LTE基站上共处5G NR（新无线电）是初始网络推出的常见策略。覆盖范围的任何差异都可以通过波束形成增益，更少的下降或增加GNODEB的发射功率来补偿。本文介绍了数据服务的初始链接预算，提供了覆盖范围预测，并针对5G NR NSA（非独立）试验的测量值在3.5GHz的辐射率为60 MHz带宽。覆盖范围预测是使用RF计划工具环礁生成的，然后将其与试验的覆盖范围测量进行比较。这些发现可用于帮助计划悉尼都会区或类似环境的未来5G网络。
When planning a 5G network in the sub-6GHz bands, similar cell planning techniques to LTE can be applied. Looking at the Australian environment, the n78 band (3.3-3.8GHz TDD) is approximately 1GHz higher than the 2.6GHz band used in existing LTE networks. As a result, the coverage footprint can be similar, and therefore co-locating 5G NR (New Radio) on existing LTE base stations is a common strategy for initial network rollout. Any difference in coverage can be compensated by beamforming gain, less downtilting, or increasing the gNodeB's transmit power. This paper presents an initial link budget for data services, provides a coverage prediction, and measurements for a 5G NR NSA (Non Stand Alone) trial radiating at 3.5GHz with 60 MHz bandwidth. The coverage prediction is generated using RF planning tool Atoll, which is then compared to coverage measurements from the trial. These findings can be used to help plan a future 5G network in the Sydney metro area or similar environment.
