5G覆盖、预测和测试
5G Coverage, Prediction, and Trial Measurements
摘要：
当在6 GHz以下频段规划5G网络时，可以应用与LTE类似的小区规划技术。从澳大利亚的环境来看，n78频段（3.3-3.8GHz TDD）比现有LTE网络中使用的2.6GHz频段高出约1GHz。因此，覆盖范围可能相似，因此在现有LTE基站上共置5G NR（新无线电）是初始网络部署的常见策略。覆盖范围中的任何差异可以通过波束成形增益、更少的下倾或增加gNodeB的发射功率来补偿。本文提出了数据服务的初始链路预算，提供了覆盖预测，并为3.5GHz和60 MHz带宽的5G NR NSA（非独立）试验提供了测量。使用RF规划工具Atoll生成覆盖预测，然后将其与试验的覆盖测量进行比较。这些发现可用于帮助规划悉尼市区或类似环境中的未来5G网络。
英文摘要：
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.
