摘　　要：文章研究了5G网络上行容量不足、上行覆盖受限以及上行传输时延变长等问题,并提出了采用FDD-NR和TDD-NR时频聚合技术来提升5G网络性能的方案。该方案主要通过深度聚合低频FDD和高频TDD载波,利用中低频段覆盖优势和中高频段大带宽优势,以提升5G上下行容量、覆盖和时延。研究表明,采用不同频段的载波深度聚合方式可以显著提高上行速率、覆盖半径以及上行时频资源利用率。智能调度功能还允许基站根据终端能力、无线条件和业务性能需求等因素,灵活选择不同工作模式,以最大化地利用频谱资源。实地验证测试结果表明,采用该方案后上行峰值速率和边缘覆盖均得到了显著提升,为5G网络性能的改善提供了有效的解决方案。The paper investigates issues concerning insufficient uplink capacity,restricted uplink coverage,and increased uplink transmission delay in 5G networks.It proposes a solution using FDD-NR and TDD-NR carrier aggregation technology to enhance the performance of 5G networks.This approach primarily involves aggregating low-frequency FDD and high-frequency TDD carriers to leverage the coverage advantage of mid-to-low frequency bands and the high-bandwidth advantage of mid-to-high frequency bands,thereby improving both uplink and downlink capacity,coverage,and latency in 5G networks.Studies indicate that adopting various forms of carrier aggregation,significantly boosts uplink speed,coverage radius,and uplink resource utilization.Intelligent scheduling also enables base stations to flexibly choose different operational modes based on terminal capabilities,wireless conditions,and service performance requirements to maximize spectrum utilization.Validation tests demonstrate significant enhancements in uplink peak rates and edge coverage after implementing this solution,providing an effective remedy for improving the performance of 5G networks.
