本申请主张在2015年9月28日在中国提交的中国专利申请No.201510629687.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开文本涉及无线通信领域的干扰处理技术，尤其涉及一种干扰处理方法、基站及网络设备。
背景技术
在长期演进技术(Long Term Evolution，LTE)的网络部署中，相邻小区由于同频部署，所以会存在同频干扰。在组网的环境下，相邻基站的传输方向一致时，位于小区边缘的用户设备(User Equipment，UE)在接收本小区下行数据时会受到相邻基站下行传输的干扰，用户上行传输由于发送功率较小对相邻小区的干扰较小。长期演进技术升级版(Long Term Evolution Advanced，LTE-A)网络中，采用异构网络来提升系统吞吐量和网络整体效率。随着网络密度和网络异构程度的不断增大，用户所受到的干扰越来越严重。为了减轻来自不同场景下的干扰，在LTE-A Release 12(R12)中对LTE的用户终端引入了基于网络协作的干扰抑制和消除技术(Network Assisted Interference Cancellation and Suppression，NAICS)来抑制或消除干扰，从而主要解决了网络中各基站传输方向一致时用户受到的邻区基站的干扰消除问题。
但是，在相关技术中，为了应对一些局部热点，或是区域偶发的一些持续一定时间的业务种类变化，网络中的部分基站可能改变上下行配置，出现与其他基站反方向的传输，从而导致终端在接收服务小区下行数据时可能受到相邻终端上行传输的数据的干扰，这些终端对终端的干扰无法通过上述的NAICS技术消除。

具体实施方式
下面将结合本公开文本一些实施例中的附图，对本公开文本一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开文本保护的范围。
本公开文本实施例提供了一种干扰处理方法，应用于第一基站，如图1所示，包括：
步骤11：获取到测量资源以及测量时隙；
步骤12：获取到第二基站为其管理的第二用户设备配置的测量信号的配置信息；
步骤13：基于所述测量信号的配置信息，控制自身管理的第一用户设备在所述测量时隙检测所述第二用户设备发起的测量信号，并获取到第一用户设备反馈的测量结果；
步骤14：基于所述第一用户设备反馈的测量结果，确定目标用户设备，针对所述目标用户设备进行干扰处理。
可选地，所述测量资源以及测量时隙的获取方式可以有以下几种：
第一种、可以由所述第一基站基于自身管理的至少一个第一用户设备上报的干扰小区信息确定目标小区列表，进而基于所述目标小区列表确定测量资源以及测量时隙；
第二种、由网络设备根据第一基站上报的目标小区列表，确定所述测量资源以及所述测量时隙，并将确定的所述测量资源以及所述测量时隙发送给所述第一基站。
本公开文本实施例提供了一种干扰处理方法，应用于第一基站，如图2所示，包括：
步骤21：基于第一用户设备上报的干扰小区信息，确定目标小区列表；其中，所述目标小区列表中包括有至少一个第二基站，所述第二基站为与所述第一基站在至少一个子帧上信号传输方向不同的基站；
步骤22：为所述目标小区列表中至少一个第二基站配置测量资源以及测量时隙，发送所述测量资源以及测量时隙至所述至少一个第二基站，使得所述第二基站基于所述测量资源以及测量时隙为其管理的第二用户设备配置测量信号，并反馈所述测量信号的配置信息至所述第一基站；
步骤23：基于所述测量信号的配置信息，控制自身管理的第一用户设备在所述测量时隙检测所述第二用户设备发起的测量信号，并获取到第一用户设备反馈的测量结果；
步骤24：基于所述第一用户设备反馈的测量结果，确定目标用户设备，针对所述目标用户设备进行干扰处理。
上述步骤21中，所述第一用户设备为所述第一基站管理的用户设备；另外，可以理解的是，所述第一基站管理的第一用户设备的数量为至少一个。
所述第一用户设备获取到干扰小区信息的方式可以为：所述第一用户设备处于所述第一基站的覆盖小区中时，检测第一基站发送的信号，如果检测到除所述第一基站外的至少一个第二基站发送的信号时，将检测到的至少一个第二基站发送的信号作为干扰信号；将干扰信号对应的第二基站覆盖的小区作为干扰小区；判断第二基站的干扰信号强度是否大于第一门限或者高于第一基站的有用信号预设值，若是，则确定将该第二基站对应的干扰小区对应的信息作为干扰小区信息进行上报；
其中，所述检测到第二基站发送的信号，可以为第二基站的同步信号或者为第二基站发送的导频信号等，这里不做赘述；所述干扰小区对应的信息可以包括：干扰小区的小区标识，所在基站的标识、干扰强度等信息的部分或全部。
上述步骤21中，所述基于第一用户设备上报的干扰小区信息，确定目标小区列表，可以包括：基于所述第一用户设备上报的干扰小区信息，获取到所述第一基站对应的干扰小区汇总列表；基于所述干扰小区汇总列表，确定目标小区列表；所述第二基站即为对第一基站管理的第一用户设备产生干扰的基站；本实施例中并不对第二基站的实际数量做出限定，第二基站可以为一个也可以为多个。
其中，所述基于所述干扰小区汇总列表，确定目标小区列表，可以包括：
基于所述干扰小区汇总列表，提取第一基站对应的干扰小区的基站列表；
基于所述基站列表，选取在每一个子帧中与所述第一基站信号传输方向不同的至少一个第二基站；
将子帧的编号、及在所述子帧中与所述第一基站信号传输方向不同的所述至少一个第二基站记录至所述目标小区列表中。其中，所述目标小区列表可以为一个也可以为至少多个，如果目标小区列表为一个，那么在该目标小区列表中可以包括有多个子帧对应的编号，以及每一个子帧对应的至少一个第二基站。如果目标小区列表为多个，那么每一个目标小区列表仅针对一个子帧，并且仅记录该子帧的编号及其对应的至少一个第二基站。不同的子帧对应的目标小区列表可能不同，需要为不同的子帧配置不同的测量时隙和测量资源。
上述信号传输方向表征信号为上行传输或下行传输。
所述与所述第一基站的至少一个子帧信号传输方向不同，可以如图3所示，在第一基站分配的第四个子帧31处，信号传输方向为上行(U)，相应的，第二基站分配的第四个子帧31处，信号传输方向为下行(D)；也就是说，在第四个时隙31处，第一基站与第二基站的子帧信号传输方向不同，反之亦然，这里不再赘述。
所述步骤22中为所述目标小区列表中第二基站配置测量资源，可以为： 为所述目标小区列表中所包含的全部第二基站配置测量资源。
其中，所述配置测量资源为：为所述目标小区列表中至少一个第二基站分配相互正交的测量资源。
所述相互正交的资源可以是同一测量时隙中以下至少一种：时域正交的资源、频域正交的资源、码域正交的资源。例如目标小区列表中有5个基站，假设正交的资源是频域正交，每个基站都是20MHz同频传输，则为每个基站配置20M中的4MHz，并将该配置信息发送给这5个基站。
其中，所述测量时隙可以为根据实际情况设置的时隙。所述测量时隙可以位于与所述第一基站不同传输方向的子帧，而不会出现在相同传输方向的时隙，例如测量时隙可位于图2中的子帧3和子帧4。测量时隙的周期可由网络侧的网络设备决定或者可以由第一基站决定，可以根据所述第一基站的上下行配置情况，服务小区内用户的移动情况等决定。
第二基站可以分别为至少一个第二用户设备分配测量子资源，假设，分配给第二基站的频域资源为4MHz，那么，第二基站可以分别为不同的第二用户设备设置不同的正交子资源，例如多个第二用户设备使用第二基站的4MHz频域资源内的正交的时域(例如位于不同的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号上)或码域(使用不同的正交码字序列)或频域(使用不同的频域RE)正交的参考信号。
本实施例中所述测量信号可以为：相关技术中的参考信号(例如，小区特定的参考信号(Cell-specific Reference Signal，CRS)，信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，解调参考信号(Demodulation Reference Signal，DMRS))中的一种或新定义的其他可以进行信号测量的参考信号。
测量信号的配置信息为能够唯一标识测量信号的资源的配置信息，可以包含测量信号的序列编号，序列移位，发送的资源时频位置，端口号等可标示测量信号的参数或参数组合。
所述测量结果可以至少包括有：测量得到的信号强度大于一定门限值的测量信号的配置信息。第一用户设备基于在第一基站指示的测量资源配置上测量到的信号强度，当该强度大于一定门限时，将该测量参考信号的配置信 息反馈给第一基站。
步骤24中，基于所述第一用户设备反馈的测量结果，确定目标用户设备可以为：第一基站根据第一用户设备反馈的测量结果中包含的测量信号的配置信息，确定对所述第一用户设备产生干扰的目标用户设备所在的第二基站，将所述测量信号的配置信息发送给相应的第二基站，使得所述第二基站根据所述测量信号的配置信息确定造成干扰的目标用户设备；
或者，第一基站根据第一用户设备反馈的测量结果中包含的测量信号的配置信息、以及测量信号的配置信息与用户设备对应关系，确定目标用户设备。
本实施例中所述进行干扰处理的方式可以为：选择避免在相同资源调度受干扰UE或是干扰UE或是将所需配置信息发送给被干扰UE进行干扰删除。
可见，通过采用上述方案，就能够基于测量时隙、以及第二基站为第二用户设备确定测量信号，控制自身管理的第一用户设备进行测量并上报的测量结果，基于所述测量结果确定所述第一用户设备的目标干扰设备，对目标干扰设备进行干扰处理。如此，就能够定位强干扰的来源，辅助进行终端间的干扰删除；由于本公开文本提供的方案是针对目标用户设备进行的干扰处理，因此，与相关技术中通过调度而减小相邻基站的干扰的方案相比，能够保证用户设备的避免业务信道及控制信道的干扰。
本实施例提供了干扰处理的示例，如图4所示，
步骤401：在普通时隙中，UE i测量邻区信号强度较强的小区列表Ai，反馈给服务小区第一基站；服务小区的第一基站将服务范围内UE上报的干扰小区列表汇总为列表B，即B＝A1∪A2∪…∪AI，其中I为反馈了强干扰小区的UE个数。
步骤402：第一基站根据邻区的UL/DL配置情况及第一用户设备上报的干扰小区列表B，判断出既属于第一用户设备上报的干扰小区列表B又是在自己下行子帧时对应为上行子帧的小区，生成目标小区列表C。
步骤403：第一基站协调目标小区列表C中的第二基站的小区使用正交资源M1调度小区的用户进行干扰测量信号的发送，并将协调的正交资源结果发送给目标小区列表C中的小区对应的第二基站，正交的资源可以是同一 测量时隙的时域，频域，码域正交。例如目标小区列表C中有5个基站，假设正交的资源是频域正交，每个基站都是20MHz同频传输，则为每个基站配置20M中4MHz，并将该配置信息发送给目标小区列表C中的小区；
步骤404：第二基站根据第一基站为其配置的资源M1，同时根据自己服务小区内至少一个第二用户设备上报的本小区信号测量信息，为测量值低于一定门限值的至少一个第二用户设备，在M1的资源内配置正交测量信号子资源(至少一个第二用户设备发送的测量信号子资源可以是码域，时域，频域正交的，或是码域、时域、频域结合的正交)；并将测量信号的配置反馈给第一基站，测量信号的配置也会指示给对应的第二用户设备。同时，在M1资源以外的区域，第二基站还可以配置本小区其他第二用户设备进行普通的业务传输。
步骤405：第一基站根据至少一个第一用户设备上报的强干扰小区，将对应的测量信号配置发送给第一用户设备；如第i个第一用户设备上报的UEi测量邻区信号强度较强的小区列表Ai，则将小区列表Ai内同时又属于目标小区列表C的小区的测量信号配置发送给第一用户设备。测量配置可以包含测量信号的序列编号，序列移位，发送的资源时频位置，端口号等可标识测量信号的参数或参数组合。
步骤406：在测量时隙，被请求发送测量信号的小区中那些配置了正交测量信号的第二用户设备发送测量信号。第一基站内的反馈了强干扰列表的第一用户设备在测量时隙完成测量，并反馈强干扰对应的测量配置(可以是一个或多个强干扰)给第一基站；
步骤407：第一基站根据各个第一用户设备反馈的测量配置确定第一用户设备对应的干扰来自于哪个或哪些第二基站，并将第一用户设备反馈的强干扰测量信号配置反馈给对应的第二基站；
步骤408：第二基站根据测量信号配置确定本小区哪个或哪些第二用户设备对第一基站的第一用户设备会造成强干扰，第二基站在本小区上行、第一基站下行子帧，如果调度了这个或这些第二用户设备，则将被调度的第二用户设备的调度配置信息发送给第一基站；
步骤409：第一基站可以选择避免在相同资源调度受干扰UE或是将所需 调度配置信息发送给被干扰UE进行干扰删除。
首先，需要配置测量时隙，这些测量时隙位于基站上下行配比不同的子帧，而不会出现在相同传输方向的时隙。可以在网络中出现与周围小区不同上下行配置的小区时由网络控制节点启用这种特有的测量时隙，或是由改变时隙配比的基站发出请求后启用，测量时隙的配置需要通知各基站。测量时隙的周期可由网络决定，根据各基站的上下行配置情况，服务小区内用户的移动情况等决定。在测量时隙由处于上行子帧的基站配置UE在相应的资源发送测量信息，处于下行子帧的部分用户进行测量。在测量时隙，其他没有被配置发送测量信息和进行测量的用户还可以进行正常的传输。
本公开文本实施例提供了一种干扰处理方法，应用于第二基站，如图5所示，包括：
步骤501：接收到测量资源以及测量时隙；
步骤502：基于所述测量资源，确定自身管理的第二用户设备对应的测量信号的配置信息，并反馈所述测量信号的配置信息至所述第一基站，使得所述第一基站将所述测量信号的配置信息以及测量时隙发送至第一用户设备；
步骤503：发送所述测量信号的配置信息以及测量时隙给所述第二用户设备，使得所述第二用户设备根据所述配置信息在所述测量时隙发出测量信号，所述测量信号用于使得所述第一用户设备基于所述测量信号的配置信息，在测量时隙处检测所述第二用户设备发起的测量信号，获取到测量结果。
这里，所述第一用户设备为所述第一基站管理的用户设备；另外，可以理解的是，所述第一基站管理的第一用户设备的数量为至少一个。
所述配置测量资源为：为所述目标小区列表中至少一个第二基站分配相互正交的测量资源。所述相互正交的资源可以是同一测量时隙中以下至少一种：时域正交的资源、频域正交的资源、码域正交的资源。
所述确定自身管理的第二用户设备对应的测量信号的配置信息，包括：为自身管理的至少一个第二用户设备确定对应的测量信号的测量子资源。测量信号的配置信息可以包含测量信号的序列编号，序列移位，发送的资源时频位置，端口号等可标示测量信号的参数或参数组合。即，第二基站可以分别为至少一个第二用户设备分配测量子资源，假设，分配给第二基站的频域 资源为4MHz，那么，第二基站可以分别为不同的第二用户设备设置不同的频域子资源，可以给其中的一个第二用户设备使用4MHz中的0.5Mhz来发送测量信号。
可见，通过采用上述方案，就能够基于测量时隙、以及第二基站为第二用户设备确定测量信号，控制自身管理的第一用户设备进行测量并上报的测量结果，基于所述测量结果确定所述第一用户设备的目标干扰设备，对目标干扰设备进行干扰处理。如此，就能够定位强干扰的来源，辅助进行终端间的干扰删除；由于本公开文本提供的方案是针对目标用户设备进行的干扰处理，因此，与相关技术中通过调度而减小相邻基站的干扰的方案相比，能够保证用户设备的避免业务信道及控制信道的干扰。

上述步骤62以及步骤63的执行顺序可以同时，也可以为先执行步骤62再执行步骤63；或者，还可以为先执行步骤63再执行步骤62。
可选地，本实施例还可以包括：基于第一用户设备上报的干扰小区信息，确定目标小区列表；其中，所述目标小区列表中包括有至少一个第二基站。
