5G新空口下eMBB与URLLC业务复用技术的研究

5G标准规范体系的演进将致力于解决不同应用场景中的多样化、差异化性能指标，适用频谱资源的缺乏要求5G新空口频段能够同时承载超高速率、超低时延业务。根据3GPP研究计划与进展，5G研究初期以eMBB为主，直到成熟期完善URLLC的标准化。本文主要从物理层设计的角度出发对eMBB与URLLC KPI及相关技术进行了讨论与研究。为了实现不同参数集配置的两种业务模型在同一频段上共存，本文分析了四种应用场景下eMBB与URLLC的两种基本复用方法，旨在减少资源浪费，提升系统的频谱效率。

5G NR-mutiplexing of eMBB and URLLC

The evolution of the 5G standardization was devoted to solving the diversified and differentiated performance indexes in different application scenarios. The lack of applicable spectrum resources required that the 5G NR spectrum resources should meet the requirements of simultaneously carrying ultra high-speed and ultra-low latency services. According to the 3GPP research plan and progress, the eMBB would be mainly studied in the initial 5G research and the URLLC standardization would be perfected until maturity. This thesis mainly discusses and studies eMBB, URLLC KPI and related technologies from the perspective of physical layer design. In order to achieve coexistence of two service models with different numerology in the same spectrum, two basic multiplexing methods of eMBB and URLLC analyzed in four application scenarios are designed to reduce resource waste and improve system spectrum efficiency.
