本公开要求享有2019年12月24日提交的名称为“定位大气波导干扰的方法、基站及计算机可读存储介质”的中国专利申请CN201911350268.7的优先权，其全部内容通过引用并入本公开中。
技术领域
本公开实施例涉及但不限于通信技术领域，尤其涉及但不限于一种定位大气波导干扰的方法、基站及计算机可读存储介质。
背景技术
TDD-LTE(Time Division Duplexing-long Term Evolution)分时长期演进是当前4G的两种制式标准之一，TDD-LTE的特点是上下行共用同一段频谱，采用时分复用传输上下行信息，下行(D子帧)和上行之间(U子帧)，采用S子帧进行隔离，其中有一段保护间隔GP(Guard Period)，GP的作用是防止远距离传输引起的时延使得远端站点的下行干扰到了本站点的上行子帧，从而引起解调性能下降；在一定的气象条件下，在大气边界层尤其是在近地层传播的电磁波受大气折射的影响其传播轨迹弯向地面，当曲率超过地球表面曲率时，电磁波部分会被陷获在一定厚度的大气薄层内，就像电磁波在金属波导管中传播一样，这种现象称为电磁波的大气波导传播。
然而，在一定的气象条件下，大气波导现象能使TDD-LTE下行无线信号传播很远，由于传播距离超过TDD-LTE***上下行保护时隙的保护距离，导致这种远端TDD-LTE下行无线信号干扰到本地TDD-LTE上行无线信号。
针对大气波导干扰，应对方案有检测、缓解和规避等，其中规避方案的理论前提是认为大气波导干扰发生时远端基站和近端基站间的干扰是相互的，即远端基站的上行也受到近端基站下行的干扰，所以施扰站下行可以发送一种含有站点信息的特征序列，被干扰的站点上行通过检测特征序列，可以唯一的确认施扰站点，而目前相关技术中，特征序列检测复杂度高，运算量大，从而导致无法使用大气波导定位功能。

具体实施方式
为了使本公开的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
实施例一：
为了解决相关技术中，同频段上各服务小区带宽无法完全对齐，使得特征序列检测复杂度高，运算量大，从而导致无法使用大气波导定位功能的问题；
本公开实施例提出一种由一基站侧实施的定位大气波导干扰的方法，请参见图1，该定位大气波导干扰的方法包括：
S101、获取标准带宽对应的特征序列；
在本公开实施例中，作为发送端的服务小区获取标准带宽对应的特征序列，其中，在30M有效频谱下，一般站点组网配置如图2所示，存在A、B、C、三种配置方式，也即在该频谱内是10M、15M、20M服务小区混合组成的，也即服务小区包括但不限于以下任一带宽服务小区：10M带宽服务小区、15M带宽服务小区、20M带宽服务小区；其中，标准带宽为预先设置的一个带宽标准，后续获取特征序列都以该标准带宽来获取；在本公开实施例中，标准带宽为10M带宽，也即，特征序列统一采用10M带宽对应点数；具体的，例如，当发送端的服务小区实际带宽为20M时，同样获取10M带宽对应点数的特征序列；当发送端的服务小区实际带宽为15M时，同样获取10M带宽对应点数的特征序列；当发送端的服务小区实际带宽为10M时，同样获取10M带宽对应点数的特征序列。需要理解的是，一个服务小区对应一个TDD-LTE基站。
S102、根据所述特征序列确定与服务小区实际带宽匹配的目标特征序列，发送所述目标特征序列。
在本公开实施例中，根据特征序列确定与服务小区实际带宽匹配的目标特征序列，发送目标特征序列包括：当特征序列的点数与服务小区实际带宽的长度对应的特征序列点数一致时，将特征序列作为目标特征序列，并发送目标特征序列。具体的，例如，当发送端的服务小区实际带宽为10M时，获取到10M带宽对应点数的特征序列，也即512点特征序列后，判断到特征序列的点数与发送端的服务小区的实际带宽的长度对应的特征序列点数512点一致，则将该特征序列特征作为目标序列特征，并发送该目标序列特征。
在本公开实施例中，根据特征序列的确定与服务小区实际带宽匹配的目标特征序列，发送目标特征序列包括：当特征序列的点数与服务小区实际带宽的长度对应的特征序列点数不一致时，对得到的特征序列进行补充处理，从而得到目标特征序列，目标特征序列的点数与服务小区实际带宽的长度对应的特征序列点数一致；发送目标特征序列；具体的，例如，在30M有效频谱内，当发送端的服务小区实际带宽为15M时，获取到10M带宽对应点数的特征序列，也即512点后，判断到特征序列的点数与发送端的服务小区实际带宽的长度对应的点数768点不一致时，则将该特征序列频域补0，做FFT(fast Fourier transform)快速傅立叶变换到15M的长度，也即做FFT变换到768后作为目标序列特征，并发送该目 标序列特征；或例如，当发送端的服务小区实际带宽为20M时，获取到10M带宽对应点数的特征序列后，判断到特征序列的点数与发送端的服务小区实际带宽的长度对应的特征序列点数1024点不一致，则将该特征序列频域补0，做FFT使得该特征序列补充到1024点，达到与服务小区实际带宽长度对应的特征序列点数一致，也即20M对应的特征序列点数1024点后作为目标序列特征，并发送该目标序列特征。
在本公开实施例中，对特征序列进行补充处理，得到目标特征序列包括：根据特征序列携带的小区标识确定服务小区在频带中所处的位置，当服务小区位于频带的高频位置时，通过在特征序列频域前端进行补充处理，得到目标特征序列；具体的，例如，在30M有效频谱内，当发送端的服务小区实际带宽为15M时，获取到10M带宽对应点数的特征序列后，判断到特征序列的点数与发送端的服务小区实际带宽的长度对应的特征序列点数不一致，且发送端的服务小区处于频谱中高频的位置时，则在该特征序列频域前端补0，做FFT到15M带宽对应的特征序列点数后作为目标序列特征，使得该目标序列特征点数与发送端的服务小区的实际带宽对应的特征序列点数一致。
在本公开实施例中，对特征序列进行补充处理，得到目标特征序列包括：根据特征序列携带的小区标识确定服务小区在频带中所处的位置，当当服务小区位于频带的低频位置时，通过在特征序列的后端进行补充处理，得到目标特征序列；具体的，例如，在30M有效频谱内，当发送端的服务小区实际带宽为15M时，获取到10M带宽对应点数的特征序列后，判断到特征序列的点数与发送端的服务小区的实际带宽对应的特征序列点数不一致，且发送端的服务小区处于频谱中低频的位置时，则在该特征序列频域的后端补0，做FFT到15M带宽对应的特征序列点数后作为目标序列特征，使得该目标序列特征的点数与发送端的服务小区实际带宽的长度对应的特征序列点数一致。
在本公开实施例执行上述定位大气波导干扰的方法后，不论发送端的服务小区的实际带宽大小，目的特征序列只会在频带的高10M或低10M位置发送，以30M频谱为例，发送端的服务小区执行上述定位大气波导干扰的方法后，目标特征序列都只会在频带的高10M或低10M位置发送，如图3所示。
本公开实施例还提供一种由另一基站侧实施的定位大气波导干扰的方法，如图4所示，该定位大气波导干扰的方法包括：
S201、接收目标特征序列；
在本公开实施例中，接收端的服务小区接收目标特征序列，其中目标特征序列由服务小区获取标准带宽长度对应的特征序列后，根据特征序列得到的与服务小区实际带宽匹配的目标特征序列。
S202、根据目标特征序列确定发送目标特征序列的服务小区；
在本公开实施例中，根据目标特征序列确定发送目标特征序列的服务小区包括：根据目标特征序列中携带的小区标识确定服务小区的宽带在频带中处于高频位置或低频位置。
在本公开实施例中，根据特征序列得到的与服务小区实际带宽匹配的目标特征序列包括：当特征序列的点数与服务小区实际带宽的长度对应的特征序列点数不一致时，对特征序列进行补充处理，得到目标特征序列，目标特征序列的点数与服务小区实际带宽的长度对应的特征序列点数一致。
需要理解的是，本公开实施例所述的定位大气波导干扰的方法并不用于限定用于30M有效频谱带宽，本方法可以运用到别的带宽，只需要增加约束：服务小区的频带必须配置在运营商有效频带频带边界的服务小区，才可以打开大气波导特征序列检测与发送功能。通过此条约束，进行全网服务小区的频带规划，以达到支持混带宽配置下的大气波导定位功能。
本公开实施例提供的定位大气波导干扰的方法，通过获取标准带宽对应的特征序列；根据所述特征序列确定与服务小区实际带宽匹配的目标特征序列，发送所述目标特征序列；通过接收目标特征序列，根据所述目标特征序列确定发送所述目标特征序列的服务小区；所述目标特征序列由所述服务小区获取标准带宽长度对应的特征序列后，根据所述特征序列得到的与所述服务小区实际带宽匹配的目标特征序列，解决了同频段上各服务小区带宽无法完全对齐，使得特征序列检测复杂度高，运算量大，从而导致无法使用大气波导定位功能的问题，降低了特征序列检测的运算量；同时，发送端的服务小区在发送目标特征序列只会在频带的高10M和低10M位置发送，对于接收端的服务小区来说，不需要判断接收到的目标特征序列对应的发送端的服务小区的类型，只采用一种方法检测，降低了特征序列检测的运算量。
实施例二：
为了更好的理解本公开，本公开实施例提供一种较为具体的例子对会议控制方法进行说明，如图5所示，该定位大气波导干扰的方法包括：
S501、发送端的服务小区根据获取到的标准带宽对应的特征序列确定与服务小区实际带宽匹配的目标特征序列；
在本公开实施例中，根据特征序列的确定与服务小区实际带宽匹配的目标特征序列，具体的，例如，在30M有效频谱内，当发送端的服务小区实际带宽为15M时，获取到10M带宽对应点数的特征序列后，判断到特征序列的点数与发送端的服务小区实际带宽的长度对应的特征序列点数不一致，且发送端的服务小区处于频谱中低频的位置时，则在该特征序列频域的后端补0，做FFT到15M的长度对应的特征序列点数后作为目标序列特征，使 得该目标序列特征的点数与发送端的服务小区实际带宽的长度对应的特征序列点数一致。
S502、发送端的服务小区发送该目标序列特征；
在本公开实施例中，得到该目标序列特征后，在发送端的服务小区的低10M位置发送。
S503、接收端的服务小区接收该目标序列特征；
在本公开实施例中，接收端的服务小区接收目标特征序列，其中目标特征序列由服务小区获取标准带宽长度对应的特征序列后，根据特征序列得到的与服务小区实际带宽匹配的目标特征序列。
S504、接收端的服务小区根据目标特征序列定位发送目标特征序列的服务小区；
在本公开实施例中，根据目标特征序列定位发送目标特征序列的服务小区包括：根据目标特征序列中携带的小区标识定位服务小区的宽带在频带中处于高频位置或低频位置。
在本公开实施例中，根据特征序列得到的与服务小区实际带宽匹配的目标特征序列包括：当特征序列的点数与服务小区实际带宽的长度对应的特征序列点数不一致时，对特征序列进行补充处理，得到目标特征序列，目标特征序列的点数与服务小区实际带宽的长度对应的特征序列点数一致。
本公开实施例提供的定位大气波导干扰的方法，发送端的服务小区通过根据获取到的标准带宽对应的特征序列确定与服务小区实际带宽匹配的目标特征序列，发送该目标序列特征，使得特征序列只在在频带的高10M和低10M位置发送；使得接收端的服务小区不用管发送端的服务小区的带宽类型，只采用一种方法检测即可，大幅度降低序列检测的运算量。
实施例三：

通信总线603用于实现处理器601和存储器602之间的连接通信；

本公开实施例中的计算机可读存储介质可用于存储一个或者多个计算机程序，其存储的一个或者多个计算机程序可被处理器执行，以实现上述实施例一和/或实施例二中的定位大气波导干扰的方法的至少一个步骤。
