Description
本公开涉及通信领域，尤其涉及确定卫星频段、频段调整方法及装置。
在无线通信技术的研究中，卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的特点是：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充，可以有以下的好处：首先，可以实现延伸覆盖，对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区，例如海洋，沙漠，偏远山区等，可以通过卫星通信来解决通信的问题。其次，可以进行应急通信，例如在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下，使用卫星通信可以快速的建立通信连接。另外还可以提供行业应用，例如对于长距离传输的时延敏感业务，可以通过卫星通信的方式来降低业务传输的时延。
可以预见，在未来的无线通信系统中，卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合，真正的实现万物智联。

在卫星网络中，LEO(Low Earth Orbit，低轨道)卫星作为典型的NGSO(Non Geostationary Orbit，非对地静止轨道)卫星，由于其星地距离小从而在传输延时和链路损耗方面的优势明显，引起了学术界和工业界更多的关注。
3GPP(3rd Generation Partnership Project，第3代合作伙伴计划)从Rel-14(Release 14，版本14)开始着手开展LEO星地融合的研究工作，目前3GPP正在积极推进卫星接入在5G(5th generation mobile networks，第5代移动通信技术)网络中的应用，研究5G新空口支持非地面网络的解决方案。频率资源是卫星互联网商用中的重要基础支撑，而受到频率资源“稀缺性”的影响，NGSO不得不与其他无线网络通信系统共享一部分的频谱资源，例如图1所示，NGSO卫星互联网与中国优先支持的地面5G系统在用频方面的共享性，如果不能良好协调好电磁频率，则会产生严重的同频或临频干扰。
针对频率资源紧缺这个低轨卫星互联网星座发展过程中的重点受限问题，如何提出相应的对策是当前面临的挑战。目前，针对卫星通信系统与陆地通信系统之间的干扰避免方面往往是通过频段的规划来避免，然而由于全球各个区域对于卫星通信以及陆地通信的频率分配方式不一致，导致仍会有干扰的问题。
为了解决上述问题，本公开提供了一种确定卫星频段、调整频段调整方案，可以有效解决解决卫星通信系统与陆地通信系统之间的干扰问题。
