背景技术
无线通信技术高速发展，无线通信系统的基站部署越来越多，而且随着5G等无线通信系统的应用，更多的频段资源以及大规模多入多出(Massive MIMO，Massive Multiple Input Multiple Output)技术的使用使得无线信号覆盖范围越来越大，导致终端在某些原本无法接入到地面无线通信系统的场景(例如在飞机机舱内)下，也能接入到地面无线通信系统中。在某些场景下终端接入到地面无线通信系统中会造成严重的后果或形成重大安全隐患，例如，在飞机机舱内，飞机起飞和降落时距离地面较近，如果乘客的终端没有正常关机，则乘客的终端可能会接入到地面无线通信系统。由于相关的无线通信协议对于乘客的终端的射频指标要求较低，部分终端的功率放大器和滤波器的性能比较差，导致在某些频段内杂散信号比较强，从无线通信协议来看，对终端的杂散信号要求比较高的时候其也仅为-50dBm/兆赫兹(MHz)，这些杂散信号会干扰飞机上的高度表等机载设备的正常工作，导致机载设备告警事件的发生，从而对航空安全形成了重大隐患。

第一方面，参照图1，本申请实施例提供一种干扰信号发送方法，包括步骤100至102。
步骤100、获取无线通信系统中正确解调的目标信号的功率接收强度；所述目标信号为终端接入所述无线通信系统需要解调的信号。
在本申请实施例中，针对目标区域为飞机机舱内部的场景，终端是指飞机上的乘客以及乘务人员所携带的终端设备，而不包括飞机上的机载设备。
在一些实施方式中，获取无线通信系统中正确解调的目标信号的功率接收强度包括：
计算在无线通信系统的目标频段内接收到的无线信号和下行同步信号之间的相关性；
根据相关性最大的无线信号确定时间和频率同步信息；
根据时间和频率同步信息解调目标信号；以及
在对目标信号解调正确的情况下，获取正确解调的目标信号的功率接收强度。
在本申请实施例中，无线通信系统可以是终端可能接入的所有无线通信系统，例如，2G无线通信系统、3G无线通信系统、4G无线通信系统、5G无线通信系统、以及未来的无线通信系统等。
在本申请实施例中，目标频段是指无线通信系统的通信频段中目标信号可能占用的通信频段，不同的无线通信系统对应的目标频段不同，一个无线通信系统对应的目标频段可以是一个，也可以是两个或两个以上。
在一个无线通信系统包括两个或两个以上目标频段的情况下，需要遍历所有的目标频段，以确定能够正确解调目标信号的目标频段。
在本申请实施例中，一个无线通信系统对应的下行同步信号可以是一个，也可以是两个或两个以上。在一个无线通信系统包括两个或两个以上下行同步信号的情况下，需要遍历所有的下行同步信号， 以确定无线通信系统下发的下行同步信号。
在本申请实施例中，目标信号为终端接入所述无线通信系统需要解调的信号是指，终端正确解调目标信号是终端成功接入无线通信系统的前提条件，也就是说，终端只有正确解调目标信号，才能成功接入无线通信系统。
在本申请实施例中，不同无线通信系统对应的目标信号可能相同，也可能不同。例如，4G无线通信系统和5G无线通信系统对应的目标信号为主系统信息块(MIB，Master Information Block)信号。
在一些实施方式中，针对目标区域为飞机机舱内部的情况，无线通信系统在目标频段内可以通过设置在飞机机舱内部的第一天线、或设置在飞机机舱外部的第一天线接收无线信号。
在一些实施方式中，所述干扰信号发送方法还包括：在对目标信号解调正确的情况下，获取所述正确解调的目标信号所占用的频域位置。
在一些实施方式中，所述干扰信号发送方法还包括：在对目标信号解调正确的情况下，获取所述正确解调的目标信号所占用的时域位置。
本申请实施例的功率接收强度可以是指单位频谱上的功率接收强度。
本申请实施例对单位频谱不作限定，例如单位频谱可以是指赫兹(Hz)、或者资源元素(RE，Resource Element)等。
步骤101、根据所述正确解调的目标信号的功率接收强度确定干扰信号的发射参数。
在一些实施方式中，根据正确解调的目标信号的功率接收强度确定干扰信号的发射参数包括：根据所述正确解调的目标信号的功率接收强度和所述正确解调的目标信号所占用的频域位置确定所述干扰信号的发射参数。
在一些实施方式中，根据正确解调的目标信号的功率接收强度和正确解调的目标信号所占用的频域位置确定干扰信号的发射参数包括：根据所述正确解调的目标信号的功率接收强度、所述正确解调 的目标信号所占用的频域位置和所述正确解调的目标信号所占用的时域位置确定所述干扰信号的发射参数。
在一些实施方式中，发射参数包括发射功率和以下至少之一：
频域带宽、数目、频域位置、或时域位置。
在一些实施方式中，根据正确解调的目标信号的功率接收强度确定干扰信号的发射功率、频域带宽和数目。
在一些实施方式中，根据正确解调的目标信号的功率接收强度确定干扰信号的发射参数包括：
根据所述正确解调的目标信号的功率接收强度在约束条件的约束下确定所述干扰信号的发射功率、频域带宽和数目；
所述约束条件为所述目标区域内的终端正确解调所述目标信号的最低接收信噪比和对所述目标信号的实际接收信噪比之差大于或等于预设阈值，所述实际接收信噪比根据所述正确解调的目标信号的功率接收强度计算得到。
在一些实施方式中，针对目标区域为飞机机舱内部的场景，实际接收信噪比为正确解调的目标信号的功率接收强度和干扰信号的发射功率之差；例如，针对第一天线设置在飞机机舱内部的情况，由于通过第一天线测量得到的目标信号的功率接收强度和飞机机舱内部的终端接收目标信号的功率接收强度相等，因此，不需要考虑无线信号从飞机机舱外部传输到飞机机舱内部的最大穿透损耗的影响；
或者，实际接收信噪比为正确解调的目标信号的功率接收强度和干扰信号的发射功率、无线信号从飞机机舱外部传输到飞机机舱内部的最大穿透损耗之差；例如，针对第一天线设置在飞机机舱外部的情况，由于通过第一天线测量得到的目标信号的功率接收强度和飞机机舱内部的终端接收目标信号的功率接收强度不相等，因此，需要考虑无线信号从飞机机舱外部传输到飞机机舱内部的最大穿透损耗的影响。
在一些实施方式中，针对目标区域为飞机机舱内部的场景，对目标信号的实际接收信噪比可以表示为
Figure PCTCN2022085267-appb-000001
那么，约束条件可以采用公式
Figure PCTCN2022085267-appb-000002
来表示；
SNR min为终端正确解调目标信号的最低接收信噪比，单位为dB；η为正确解调的目标信号的功率接收强度，单位为dBm/Hz；N为干扰信号的数目；P i为第i个干扰信号每赫兹的发射功率，单位为dBm/Hz；W i为第i个干扰信号的频域带宽，单位为Hz；B为无线通信系统中正确解调的目标信号所占用的频域带宽，单位为Hz；λ取0或1，λ的具体取值与第一天线的位置相关，例如，在第一天线位于飞机机舱外部的情况下，λ取1；在第一天线位于飞机机舱内部的情况下，λ取0；PL为无线信号从飞机机舱外部传输到飞机机舱内部的最大穿透损耗，单位为dB；以及，X为预设阈值，单位为dBm。
本申请实施例中，将在一个子载波上发送的干扰信号看作是一个干扰信号。
在一些实施方式中，N个干扰信号的频域带宽之和为正确解调的目标信号的频域带宽。
通过上述公式可以得到每一个干扰信号的发射功率和频域带宽、以及干扰信号的数目。
在一些实施方式中，根据正确解调的目标信号所占用的频域位置确定干扰信号的频域位置。
在一些实施方式中，干扰信号的频域位置包括：所述正确解调的目标信号所占用的频域位置中的部分或全部频域位置。
在一些实施方式中，可以根据正确解调的目标信号所占用的时域位置确定干扰信号的时域位置，也可以直接确定干扰信号的时域位置为无线通信系统的全部时域位置。
在一些实施方式中，干扰信号的时域位置包括：
所述正确解调的目标信号所占用的时域位置；
或者，所述无线通信系统的全部时域位置；
或者，所述正确解调的目标信号所占用的时域位置、以及根据所述正确解调的目标信号所占用的时域位置和所述目标信号的发送周期计算得到的时域位置。
本申请实施例对干扰信号的具体形式不作限定，例如干扰信号可以为固定序列或随机生成序列。
本申请实施例对干扰信号的发射内容不作限定，例如可以是方波或窄带脉冲等。
步骤102、基于所述干扰信号的发射参数发送所述干扰信号，使得位于目标区域内的终端无法正确解调所述目标信号。
在一些实施方式中，目标区域为在特定场景下不允许终端接入无线通信系统的区域。例如，目标区域为飞机机舱内部，在飞机起飞和降落时不允许飞机机舱内部的终端接入地面无线通信系统。
在一些实施方式中，基于干扰信号的发射参数发送干扰信号包括：
基于所述干扰信号的发射参数通过设置在所述飞机机舱内部的第二天线发送所述干扰信号。
在本申请实施例中，由于发送干扰信号的目的是对飞机机舱内部的终端接收目标信号产生影响，可以将用于发送干扰信号的第二天线设置在飞机机舱内部，以降低干扰信号的发射功率，节约资源。
在本申请实施例中，在第一天线设置在飞机机舱内部的情况下，第一天线和第二天线可以采用同一个天线实现。
在一些实施方式中，基于干扰信号的发射参数发送干扰信号包括：
根据干扰信号的发射功率、频域带宽和数目在对应的时域位置和频域位置发送对应数量的干扰信号。
本申请实施例提供的干扰信号发送方法，由于终端正确解调目标信号是终端成功接入无线通信系统的前提条件，因此，本申请实施例通过发送干扰信号，使得位于目标区域内的终端无法正确解调目标信号，也就使得位于目标区域内的终端无法成功接入无线通信系统，从而避免了由于终端接入无线通信系统造成的严重后果或形成的重大安全隐患。
下面通过两个具体示例详细说明本申请实施例的干扰信号发送方法的具体实现过程，所列举的示例仅仅是为了说明方便，并不用于 限定本申请实施例的保护范围。
示例1
某场景下地面无线通信系统为基于第三代合作伙伴计划(3GPP，the 3rd Generation Partnership Project)的标准频分双工(FDD，Frequency Division Duplexing)长期演进(LTE，Long Term Evolution)无线通信系统，该无线通信系统的上行工作频段为1755兆赫兹(MHz)至1785MHz，下行工作频段为1850MHz至1880MHz，有的FDD LTE无线通信系统的下行工作频段分为1850MHz至1860MHz和1860MHz至1880MHz两段。
图2为本申请实施例的示例1提供的MIB信号的时域和频域位置的示意图。如图2所示，LTE无线通信系统下行采用小区特定参考信号(CRS，Cell-specific Reference Signal)4端口方式，LTE无线通信系统的下行同步信道包括：主同步信道(P-SCH，Primary Synchronization Channel)和辅同步信道(S-SCH，Secondary Synchronization Channel)，MIB信号承载在物理广播信道(PBCH，Physical Broadcast Channel)中进行传输，如图2所示，按照协议规定，PBCH在频域上占用LTE无线通信系统的下行工作频段的中心频点的72个子载波(即72个RE)，PBCH占用的频段长度为(72×15千赫兹(kHz))＝1080kHz，平均分布在FDD LTE无线通信系统的中心频点的两侧，具体位于1869.46MHz至1870.54MHz的频段。
通过设置在飞机机舱外的第一天线接收FDD LTE无线通信系统的目标频段1860MHz至1880MHz内的无线信号；计算接收到的无线信号和下行同步信号之间的相关性；根据相关性最大的无线信号确定时间和频率同步信息；根据时间和频率同步信息解调PBCH所承载的MIB信号；假定在1869.46MHz至1870.54MHz频段上解调PBCH的循环冗余校验码(CRC，Cyclic Redundancy Check)正确，说明在此频段能够正确解调MIB信号，可知FDD LTE无线通信系统带宽为20MHz，且获得正确解调的MIB信号每赫兹的功率接收强度为-126dBm。
图3为本申请实施例的示例1提供的干扰信号的时域和频域位置的示意图。如图3所示，假设终端正确解调PBCH的最低接收信噪 比(SNR，Signal to Noise Ratio)设定为-5dB，本示例的第一天线设置在飞机机舱外，则PL为20dB，λ取1，设定干扰信号频段为整个1.08MHz带宽，预设阈值为3dBm。
干扰信号在单位频率上的发射功率可根据如下公式计算得到：
Figure PCTCN2022085267-appb-000003
P i为第i个干扰信号每赫兹的发射功率，在本示例中，每个RE对应一个干扰信号，并且所有RE对应的干扰信号的发射功率均相等。
通过上述公式计算得到单位频率的干扰信号的发射功率需要大于等于-138dBm/Hz，对应到每个RE的干扰信号的发射功率要大于-97dBm。
干扰信号发送的时域位置可以选择为在整个时域内进行发送，如图3所示。另外，干扰信号发送的时域位置也可以选择为仅在PBCH所发送的时间周期内进行发送，如图4所示，具体的PBCH发送时间周期可以从MIB信号中获取，本示例中MIB信号的发送时间周期为10毫秒(ms)，每个时间周期内干扰信号发送所占用的时间长度为4个正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)符号，大约为(4/14)＝0.286ms。
本示例中，通过以上任意一种发送方式发送干扰信号后，飞机机舱内的终端都无法接入到该地面FDD LTE无线通信系统中，从而避免终端接入该地面FDD LTE无线通信系统后对飞机的高度表等机载设备产生干扰。
示例2
某场景下地面无线通信系统为基于3GPP的标准时分双工(TDD，Time Division Duplexing)新无线(NR，New Radio)无线通信系统，下行工作频段为4800MHz至4900MHz。
图5为本申请实施例的示例2提供的MIB信号的时域和频域位置的示意图，如图5所示，NR无线通信系统的下行同步信号包括主同步信号(PSS，Primary Synchronization Signal)和辅同步信号(SSS，Secondary Synchronization Signal)，MIB信号承载在PBCH 中进行传输，由PSS、SSS、PBCH三部分共同组成同步信号和PBCH块(Synchronization Signal and PBCH block,SSB)。如图5所示，按照协议规定，SSB的频域映射在NR无线通信系统的下行工作频段的240个子载波上，PBCH占用的频段长度为(240×30kHz)＝7200kHz，具体位于频段4800MHz至4807.2MHz。通过设置在飞机机舱内的第一天线接收TDD NR无线通信系统的目标频段4800MHz至4900MHz内的无线信号；计算接收到的无线信号和下行同步信号之间的相关性；根据相关性最大的无线信号确定时间和频率同步信息；根据时间和频率同步信息解调PBCH所承载的MIB信号；假定在4800MHz至4807.2MHz的频段上解调PBCH的CRC正确，说明在此频段能够正确解调MIB信号，可知TDD NR无线通信系统带宽为100MHz，且获得正确解调的MIB信号每赫兹的功率接收强度为-145dBm。
图6为本申请实施例的示例2提供的干扰信号的时域和频域位置的示意图。如图6所示，假设终端正确解调PBCH的最低接收信噪比设定为-6dB，本示例的第一天线设置在飞机机舱内，则λ取0，PL为20dB，设定干扰信号频段为整个7.2MHz带宽，预设阈值为5dBm。
干扰信号在单位频率上的发射功率可根据如下公式计算得到：
Figure PCTCN2022085267-appb-000004
P i为第i个干扰信号每赫兹的发射功率，在本示例中，每个RE对应一个干扰信号，并且所有RE对应的干扰信号的发射功率均相等。
通过上述公式计算得到单位频率的干扰信号的发射功率需要大于等于-134dBm/Hz，对应到每个RE的干扰信号的发射功率要大于-89dBm。
干扰信号发送的时域位置选择为仅在SSB所发送的时间周期内进行发送，如图6所示，具体的SSB发送时间周期可以从MIB信号中获取，每个SSB组内有8个SSB块，本示例中MIB信号的发送时间周期为20ms，每个SSB块的时间周期内干扰信号发送占用的时间长度为3个OFDM符号，大约为(3/28)＝0.107ms。
本示例中，通过以上发送方式发送干扰信号后，飞机机舱内的 终端都无法接入到该地面TDD NR无线通信系统中，从而避免终端接入该地面TDD NR无线通信系统后对飞机的高度表等机载设备产生干扰。
