摘　　要：作为未来6G星地融合通信的前瞻性探索,5G-A针对非陆地通信的应用场景、频谱、关键通信技术以及面临的挑战等展开了系统研究。针对卫星物联网下的大连接需求,基于现有协议中的NPUSCH信道传输结构,设计了不同颗粒度下的码分方案,并基于NTN场景下典型假设进行了性能评估。仿真结果表明所提方案能够有效提升卫星物联网的下上行通信容量。As a prospective exploration of future 6G satellite-terrestrial integration communications,5G-A has conducted systematic research on the application scenarios,spectrum,key communications technologies,and challenges of 5G-A NTN communications.In response to the large connection requirements of loT-NTN,a code division scheme of different granularity is designed based on the NPUSCH channel transmission structure in existing specification,and performance evaluation is carried out based on typical assumptions in NTN scenarios.The simulation results show that the proposed scheme can effectively improve the uplink communication capacity of the loT-NTN.
