参见图2，ATG应用技术存在的干扰场景：
(1)ATG系统与其它系统或管制区域(如边境、地区)之间的干扰：
ATG基站——>射电天文或管制区域(如边境，地区)的干扰；
ATG终端——>射电天文或管制区域(如边境，地区)的干扰。
对于ATG系统与其它系统或管制区域(如边境、地区)之间的干扰，涉及到ATG与其它系统如射电天文或雷达等同频或邻频的业务保护，ATG基站和ATG终端也需要考虑监管区域的辐射限制，如在边境或部分区域内部署ATG网络，需要考虑满足对其它国家或区域的监管要求。

ATG基站<——>地面基站的间干扰；
ATG基站<——>地面终端的间干扰；
ATG终端<——>地面基站的间干扰；
ATG终端<——>地面终端的间干扰。
对于ATG与地面通信系统之间，干扰相对严重的场景为地面基站和ATG 终端的干扰，包括宏覆盖下的农村基站或地面小站，地面基站的很容易对ATG终端造成干扰，导致灵敏度下降。同时ATG终端的上行发射，也对地面基站和地面终端造成干扰。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(Ultra Mobile Broadband，UMB)、演进型UTRA((Evolution-UTRA，E-UTRA))、IEEE 802.11((Wi-Fi))、IEEE 802.16((WiMAX))、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织 的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。
本申请实施例是针对干扰场景比较严重的ATG终端(上行)发射对地面基站(上行)接收/地面终端(下行)接收场景开展的干扰抑制方法：
搭载有ATG终端(比如CPE类型)的飞机，在空中航行时，ATG终端的发射信号对地面基站或地面终端会造成接收干扰，对于同频非同步的应用场景，ATG终端对地面基站或者地面终端的干扰是不能被忽略的，本申请实施例通过如下几种方法进行干扰抑制：
1)ATG CPE波束赋形和波束对应(beam correspondence)能力的应用：
ATG终端和地面基站都利用波束赋形能力，增强定向发送和接收增益，通过波束赋形将波束指向ATG基站，抑制了ATG终端对地面基站或地面终端的干扰，同时也降低地面基站对ATG通信系统的ATG终端的干扰。
为了进一步降低ATG终端上行发射对地面基站或者其他通信系统的接收机造成干扰，除了波束赋形的应用，可以在ATG CPE采用beam correspondence能力，该能力可用来使ATG终端基于下行的测量来选择一个最适合的上行发射信息，如某些ATG终端可基于波束扫描来具备beam correspondence能力，而部分ATG终端不需要基于波束扫描就具备beam correspondence能力。
ATG终端的波束选择能力可以使该ATG终端基于下行(Downlink，DL)测量选择一个适合的上行(Up Link，UL)发射波束，该能力可以减少波束扫描范围精准ATG终端的下行发射功率，比如ATG终端具备该波束选择能力，该ATG终端从射频性能的技术提升，可提高ATG终端的等效全向辐射功率(Equivalent Isotropically Radiated Power，EIRP)，相对于ATG终端不具备此波束定位能力可以考虑被优化XdB，或者定义容差(tolerance)概念来区别ATG终端具备或不具备该beam correspondence能力带来的射频性能差异。
高精度的EIRP可以更加精准的确定ATG终端的波束方向性，从而提高ATG终端覆盖的同时并规避了ATG终端对地面基站或终端的干扰。本申请实施例提出针对ATG终端和应用场景引入相关波束能力的方案。
2)ATG终端的功率控制：
ATG通信系统是通过地面ATG基站和ATG终端(比如CPE类型)间的通信，飞机乘客是通过Wi-Fi实现手机终端(UE)和ATG终端的连接，因此需要ATG终端上报终端类型，网络测根据终端类型下发接入允许指示，实现ATG终端的接入允许，并避免ATG基站和地面终端(例如NR UE)和飞机上乘客的终端(比如NR UE)的接入。
在一些实施方式中，ATG终端可以根据其搭载的飞行器的实际飞行参数上报相关信息，比如上报以下一项或多项组合：ATG终端类型、功率等级类型、高度、经纬度、地理位置、速度和区域监管信息，给ATG基站，该ATG基站可以根据接收到的上述信息，比如ATG终端类型、功率等级类型、高度、经纬度、地理位置、速度和区域监管信息中的一项或多项组合，可以通过广播信息下发信令，指示ATG终端的允许发射功率值、允许发射功率范围或允许发射功率等级，通过ATG终端和ATG基站的信令交互，可以控制ATG终端在经过地面通信基站密集区域、低空爬行(比如低于某一高度)、其它被保护通信系统或管制区域(比如边境、地区)时，调整天线增益大小或降低输出功率满足区域要求。
在另一些实施方式中，ATG基站可以通过存储的基站密集区域、低空爬行(比如低于某一高度)、其它被保护通信系统或管制区域(比如边境、地区)，下发指示给ATG终端进行的天线增益大小或降低输出功率满足区域要求。
在又一些实施方式中，ATG终端也可以存储基站密集区域、低空爬行(比如低于某一高度)、其它被保护通信系统或管制区域(如边境、地区)等信息，当飞行器经过这些有特殊规定的区域时，ATG基站可以根据ATG终端上报的相关信息，对ATG终端进行调整天线增益大小或降低输出功率满足区域要求。
