摘　　要：阐述针对传统广播技术频谱资源利用不足、传输模式单一等问题,提出基于5GNR多播架构的自适应传输策略,结合单频网组播与分层调制技术,构建多场景适配的广播传输模型,优化物理层资源块分配算法与动态多播组管理机制。该系统在蜂窝网络覆盖场景下显著提升了吞吐量性能,降低了端到端传输时延,并在频谱效率与服务质量方面展现出优于传统广播模式的特性。This paper expounds the problems of insufficient spectrum resource utilization and single transmission mode in traditional broadcasting technology,and proposes an adaptive transmission strategy based on 5GNR multicast architecture.Combining single frequency network multicast and layered modulation technology,a multi scenario adaptive broadcasting transmission model is constructed,and the physical layer resource block allocation algorithm and dynamic multicast group management mechanism are optimized.This system significantly improves throughput performance in cellular network coverage scenarios,reduces end-to-end transmission latency,and exhibits superior spectral efficiency and service quality compared to traditional broadcast modes.
