摘　　要：基于中国联通“空天地一体化”网络演进计划,低轨高通量星座系统及空地一体技术将是未来移动通信的重要研究方向。面向低轨高通量星座系统建设,首先对低轨高通量星座用户需求、波束特点、波束种类进行了分析,然后针对业务点波束进行设计,主要包括用户接入方案设计、频率选择、带宽选择,并通过链路预算验证了波束设计的可行性。Based on the China Unicom’s "space-air-ground integration" network evolution plan,LEO Ka constellation system and its space-ground integration technology will be an important research content of the future mobile communication. Aiming at the construction of LEO high-throughput constellation system,it firstly analyzes the user requirements,beam characteristics and beam types of LEO high-throughput constellation,and then it designs for business spot beam,which mainly includes user access scheme design,frequency selection,bandwidth selection,and finally it verifies the feasibility of beam design through link budget.
