| 摘 要： |
The high-altitude platform station (HAPS) is a promising solution for extreme coverage extension in the Fifth Generation (5G) Evolution and Sixth Generation (6G) eras. By providing radio waves from the stratosphere using HAPS, mobile communications can be made available in all locations that are not adequately covered by conventional mobile communications networks. It is desirable that the HAPS and terrestrial system share a frequency to actualize a direct access service in which terminals connected to the terrestrial International Mobile Telecommunications (IMT) network at 2.7 GHz or less can directly connect to the HAPS. In this paper, we propose a 3D-cell control technology as a load balancing and interference avoidance mechanism when HAPS and terrestrial network share a frequency. Evaluation results based on a 6G system-level simulator show that the load balance and interference-to-noise ratio characteristics are improved in the 2 GHz band.
高海拔平台站（HAPS）是第五代（5G）和第六代（6G）时代实现极端覆盖扩展的一种有前景的解决方案。通过利用HAPS从平流层发射无线电波，可使移动通信覆盖到传统移动通信网络无法充分覆盖的所有区域。理想情况下，HAPS与地面系统共享频率，以实现直接接入服务，即连接至地面国际移动通信网（IMT）2.7 GHz或更低频段终端可直接接入HAPS。本文提出了一种三维蜂窝控制技术，作为HAPS与地面网络共享频率时的负载均衡和干扰规避机制。基于6G系统级仿真器的评估结果表明，在2 GHz频段内，负载均衡性能和信噪比特性均得到改善。 |
