具体实施方式
目前，UDN中，由于部署的小小区基站特别多，相邻的小小区基站之间的距离特别近，使得小小区基站之间干扰严重。因此，部署UDN时，如何对小小区基站之间的干扰进行协调实为业界亟待解决的问题。

本发明实施例中，载波正交，是指两个不同的载波集，各自包含的载波不同，即载波不重合；载波非正交，是指两个不同的载波集，各自包含的载波部分或全部相同，即载波重合。
下面，为描述方便、清楚起见，以系统架构具体为UDN系统为例对本发明技术方案进行详细描述。具体的，请参见图1。
图1为本发明干扰协调方法所适用的UDN的架构示意图。如图1所示，eNB1、eNB2与eNB3为UDN中相邻的三个小小区基站。UE1为eNB1下的中心UE，UE2为eNB2下的边缘UE。本发明实施例中，为每个小小区基站配置第一载波集和/或第二载波集。其中，第一载波集记为MC集，第一载波集中的载波称之为成员载波(Mandatory Carrier，MC)，该些MC为能免于周围干扰源的干扰的载波；第二载波集记为OC集，第二载波集中的载波称之为可选载波(Optional Carrier，OC)，该些OC为可以被快速激活或者去激活的载波。下面，在图1的基础上，分别从小小区基站与小小区基站之间交互的角度，以及小小区基站与UE之间交互的角度，对本发明干扰协调方法进行详细说明，具体的，可参见图2与图3。
图2为本发明干扰协调方法实施例一的信令图。本实施例中，小小区基站与小小区基站之间交互，适用于需要进行干扰协调的场景。具体的，本实施例包括如下步骤：
101、第一小小区基站生成载波协调信息。
其中，所述载波协调信息用于指示所述第一小小区基站的第一载波集和/或第二载波集，其中，第一载波集，即MC集中的载波为不被其他小小区基站的MC集中的载波干扰的载波，也就是说，第一小小区基站的MC集与其他小小区基站的MC集正交。一般来说，第一小小区基站可以将本基站下的任意UE调度在MC集中的任意一个载波上，调度周期较长，一般通过半静态方式调度。第二载波集，即OC集中的载波为能够容忍一定程度干扰的载波，第一小小区基站也可以对该些载波的功率进行一定程度的调整，对UE的调度具有一定的限制。例如，对于第二载波集中被配置为非几乎空白子帧(Almost Blank Subframe，ABS)的载波，可以用于调度中心UE；而对于第二载波集中被配置为ABS的载波，可以用于调度边缘UE。
本步骤中，第一小小区基站可接收其他小小区基站发送的载波协调信息，根据该载波协调信息以及自身支持的CC等，为自身配置第一载波集和/或第二载波集，第一小小区基站根据该配置生成载波协调信息。
102、第一小小区基站向第二小小区基站发送所述载波协调信息。
103、第二小小区基站为自身配置第三载波集和/或第四载波集。
步骤102与步骤103中，第一小小区基站将指示自身的第一载波集和/或第二载波集的载波协调信息发送给第二小小区基站，使得第二小小区基站根据该载波协调信息，为自身配置第三载波集/和或第四载波集。其中，第三载波集包含的各载波与所述第一载波集包含的各载波相互正交；第二载波集包含的各载波与所述第四载波集包含的各载波非正交。其中，第一载波集包含的各载波与第二载波集包含的各载波正交，是指第一载波集与第二载波集中的载波各不相同，即载波不重合；第二载波集包含的各载波与第四载波激波包含的各载波非正交，是指第二载波集与第四载波集中部分或全部载波相同，即载波重合。
本发明实施例提供的干扰协调方法，第一小小区基站生成指示自身的第一载波集和/或第二载波集的载波协调信息，并将该载波协调信息发送给第二小小区基站，使得第二小小区基站根据该载波协调信息为自身配置第三载波集/和或第四载波集。该过程中，由于第二小小区基站为自身配置的第三载波聚包含的载波与第一小小区基站的第一载波集中的载波正交，使得第一小小区基站的第一载波集中的载波，与第二小小区基站的第三载波集中的载波互不干扰。也就是说，对于一个具体的小小区基站，其可根据其他小小区基站发送的载波协调信息为自身配置MC集与OC集，每个小小区基站都可以配置不被其他小小区基站干扰的MC载波集和能够容忍一定程度干扰的OC载波集。如此一来，采用MC载波集中的载波调度边缘UE和/或中心UE，并根据OC载波集中的载波是否配置ABS来决定中心UE或边缘UE的调度，从而降低各小小区基站之间的干扰。
可选的，本发明实例中，所述第二载波集、所述第三载波集与所述第四载波集至少满足下述条件之一：
所述第一载波集包含的各载波与第二载波集包含的各载波正交、所述第一载波集包含的各载波与第四载波集包含的各载波正交、所述第二载波集包 含的各载波与所述第三载波集包含的各载波正交、所述第二载波集包含的各载波与所述第四载波集包含的各载波非正交。
具体的，本发明实施例中，对于两个相邻的小小区基站，即第一小小区基站与第二小小区基站，在保证该两个小小区基站的MC集相互正交的前提下，可灵活配置该两个小小区基站各自的OC集。例如，请参照图1，eNB1的MC集包含的载波为C1、C3；eNB1的OC集包含的载波为C6、C7；eNB2的MC集包含的载波为C2；eNB2的OC集包含的载波为C6、C7、C8；eNB3的MC集包含的载波为C4、C5；eNB3的OC集包含的载波为C6、C8。由此可知，eNB1的MC集、eNB2的MC集与eNB3的MC集相互正交，而eNB1的OC集、eNB2的OC集与eNB3的OC集相互非正交。
可选的，本发明实施例中，第一小小区基站向第二小小区基站发送所述载波协调信息，使得第二小小区基站为自身配置第三载波集和/或第四载波集的过程可参见图3。
图3为本发明干扰协调方法中载波集的配置过程示意图，其包括如下步骤：
201、第一小小区基站向第二小小区基站发送载波协调信息，该载波协调信息用于指示第一小小区基站的第一载波集。
202、第二小小区基站根据载波协调信息，确定自身的第三载波集。
203、第二小小区基站向第一小小区基站发送载波协调信息，该载波协调信息用于指示第二小小区基站的第四载波集。
204、第二小小区基站向第一小小区基站发送载波状态信息。
具体的，第二小小区基站周期性或事件触发性的向第一小小区基站发送载波状态信息，该载波状态信息包括第四载波集中的对应载波上边缘UE的数据和/或负载等。
205、第一小小区基站根据载波状态信息，确定第二载波集。
206、第一小小区基站向第二小小区基站发送载波协调信息，该载波协调信息用于指示第一小小区基站的第一载波集和/或第二载波集。
通过上述方式，可以将第一小小区基站的第一载波集和/或第二载波集的信息扩散至第一小小区基站的所有相邻小小区基站。当第一小小区基站 将自身的第一载波集指示给所有相邻的小小区基站时，可以减少UE的盲检测复杂度。
可选的，本发明实施例中，第一小小区基站获取测量结果，所述测量结果指示所述第二小小区基站在第一载波上的负载和/或干扰，所述第一载波属于所述第二载波集。进一步的，第一小小区基站根据所述测量结果，生成指示信息并向第二小小区基站发送，所述指示信息用于指示第一小小区基站激活和/或去激活所述第一载波。
具体的，第一小小区基站可以检测相邻小小区基站在OC集中每个OC上的负载和干扰情形，并且基于这些测量决定是否将该OC激活或去激活。第一小小区基站可通过如下几种方式获取测量结果：
方式一、第一小小区基站监听所述第二小小区基站在所述第一载波上的负载和/或干扰，以获取所述测量结果。
该种方式下，第一小小区基站自己监听第二小小区基站在第一载波上干扰和/或负载。
方式二、所述第一小小区基站接收用户设备发送的汇报信息，根据所述汇报信息获取所述测量结果，所述汇报信息指示所述第二小小区基站在所述第一载波上的负载和/或干扰。
该种方式下，第一小小区基于服务UE上报的汇报信息获取测量结果，例如，图1中，当第一小小区基站具体为eNB1、第二小小区基站eNB2或eNB3、第一载波为C6或C7时，UE对eNB2或eNB3在C6(或C7)上的负载和/或干扰进行监测得到的汇报信息并发送给eNB1，由eNB1根据该汇报信息获取测量结果。
方式三、所述第一小小区基站接收所述第二小小区基站发送的载波状态信息，根据所述载波状态信息，获取所述测量结果，其中，所述载波状态信息指示边缘区域中的用户设备在所述第一载波上的数目和/或负载，所述边缘区域为所述第二小小区基站覆盖区域中的边缘区域。
该种方式下，第一小小区基站与第二小小区基站之间通过X2接口进行信令交互，从而获得测量结果。
上述获取测量结果的过程中，第一小小区基站可以配置为周期性的获取测量结果，或者事件触发性的获取测量结果，本发明并不以此为限制。
可选的，本发明实施例中，载波协调信息可以具体为位图(bit map)、比特流等。
在一种实现方式中，当载波协调信息具体为位图时，第一小小区基站生成载波协调信息的过程具体为：所述第一小小区基站生成第一位图，所述第一位图包含N个比特位，不同比特位对应不同的载波，所述N个比特位中，置1的比特位指示与该比特位对应的载波属于所述第一载波集，置0的比特位指示与该比特位对应的载波不属于所述第一载波集；
和/或，
所述第一小小区基站生成第二位图，所述第二位图包含N个比特位，不同比特位对应不同的载波，所述N个比特位中，置1的比特位指示与该比特位对应的载波属于所述第二载波集，置0的比特位指示与该比特位对应的载波不属于所述第二载波集。
具体的，可以在X2接口上引入两个bit map。例如，当存在32种载波时，可引入两个32比特的bit map，每个bit map中，每个bit位对应一种载波。该两个bit map即为上述的第一位图与第二位图。第一位图对应MC集，该第一位图中，每个置1的bit位指示该bit位对应的载波被用作MC集中的载波，如果置0，则表示未被用作MC集中的载波；第二位图对应OC集，该第二位图中，每个置1的bit位指示该bit位对应的载波被用作OC集中的载波，如果置0，则表示未被用作OC集中的载波。
上述实现方式中，位图包含的比特位用于指示该比特位对应的载波是否属于一个载波集。然而，本发明并不以此为限制，在其他可行的实现方式中，位图包含的比特位也可以用于指示该比特位对应的载波是否为激活载波。
具体的，在另一种实现方式中，当载波协调信息具体为位图时，第一小小区基站生成载波协调信息的过程具体为：所述第一小小区基站生成第三位图，所述第三位图包含N个比特位，所述N个比特位分别对应所述第一载波集中的不同载波，所述N个比特位中，置1的比特位指示与该比特位对应的载波为激活载波，置0的比特位指示与该比特位对应的载波为未激活载波；
和/或，
所述第一小小区基站生成第四位图，所述第四位图包含N个比特位，所述N个比特位分别对应所述第二载波集中的不同载波，所述N个比特位中，置1的比特位指示与该比特位对应的载波为激活载波，置0的比特位指示与该比特位对应的载波为未激活载波。
上述实现方式中，是为每个集合，即MC集与OC集分别引入不同的bit map。然而，本发明并不以此为限制，在其他可行的方式中，也可以只引入一个bit map以减少bit map。此时，在一种实现方式中，当比特位指示该比特位对应的载波是否属于一个载波集，第一小小区基站生成第五位图，所述第五位图包含N个比特位，不同比特位对应不同的载波，所述N个比特位包含第一比特位集合与第二比特位集合；其中，所述第一比特位集合中，置1的比特位指示与该比特位对应的载波属于所述第一载波集，置0的比特位指示与该比特位对应的载波不属于所述第一载波集；所述第二比特位集合中，置1的比特位指示与该比特位对应的载波属于所述第二载波集，置0的比特位指示与该比特位对应的载波不属于所述第二载波集。
在另一种实现方式中，当比特位用于指示该比特位对应的载波是否为激活载波时，所述第一小小区基站生成第六位图，所述第六位图包含N个比特位，所述N个比特位包含第一比特位集合与第二比特位集合，所述第一比特位集合中的不同比特位分别对应所述第一载波集中的不同载波，所述第二比特位集合中的不同比特位分别对应所述第二载波集中的不同载波；其中，所述第一比特位集合与所述第二比特位集合中，置1的比特位指示与该比特位对应的载波为激活载波，置0的比特位指示与该比特位对应的载波为未激活载波。
可选的，上述实施例中，第二载波集中各载波的功率可调整。
可选的，上述实施例中，第一载波集中的载波用于调度边缘用户设备和/或中心用户设备；所述第二载波集中的载波被配置为非几乎空白子帧ABS时，用于调度中心用户设备，或者，所述第二载波集中的载波被配置为ABS时，用于调度边缘用户设备。
图4为本发明干扰协调方法实施例二的信令图。本实施例中，小小区基站与UE之间交互，适用于需要进行干扰协调的场景。具体的，本实施例包括如下步骤：
301、第一小小区基站生成测量资源限制信息，所述测量资源限制信息用于指示所述第一小小区基站的第一载波集和/或第二载波集中的激活载波。
通常来说，eNB比UE支持更多的成员载波(Componenet，CC)，若UE能进行载波间的快速切换，则相较于载波聚合技术，可以减少UE的复杂度以及能量消耗。同时，允许UE接入整个可获得的eNB频谱资源，并且，快速载波切换可以改善干扰协调/负载均衡，充分利用多载波的先听后说(Listen Before Talk，LBT)。
具体的，第一小小区基站可接收其他小小区基站发送的载波协调信息，根据该载波协调信息以及自身支持的CC，为自身配置第一载波集与第二载波集。一般来说，第一小小区基站的第一载波集，即MC集中的载波为不被其他小小区基站的MC集中的载波干扰的载波，也就是说，第一小小区基站的MC集与其他小小区基站的MC集正交。第二载波集，即OC集中的载波为能够容忍一定程度干扰的载波，该些载波为可以灵活的激活或去激活的载波，即第一小小区基站可以对该些载波作出快速激活或去激活的决定。如此一来，可以使得第一小小区基站对第二载波集中的OC进行快速载波自适应选择，但没有触发第一小小区基站进行测量资源限制的重配置。
本步骤中，第一小小区基站生成的测量资源限制信息用于指示自身的第一载波集和/或第二载波集中的激活载波。然而，本发明并不以此为限制，在其他可行的实现方式中，测量资源限制信息也可以用于指示下述信息中的至少一个：第一载波集、第一载波集中的激活载波、第二载波集、第二载波集中的激活载波等。
302、所述第一小小区基站向用户设备UE发送所述测量资源限制信息，使得所述UE根据所述测量资源限制信息对所述第一载波集中的载波和/或第二载波集中的激活载波进行测量。
303、UE对所述第一载波集中的载波和第二载波集中的激活载波进行测量。
上述步骤302与303中，第一小小区基站将指示自身的第一载波集和/或第二载波集的测量资源限制信息发送给UE，使得UE对第一载波集中的载波和第二载波集中的激活载波进行监听或检测等。例如，若UE为中心UE，则采用第一载波集中的载波或第二载波集中的载波对该UE进行调度；再如， 若UE为边缘UE，则采用第一载波集中的载波对该UE进行调度；或者，采用第二载波集中的载波对应的ABS子帧对该UE进行调度，其中，第二载波集中的载波为配置有ABS的载波。
本发明实施例提供的干扰协调方法，第一小小区基站生成指示自身的第一载波集和/或第二载波集中的激活载波的测量资源限制信息，并将该测量资源限制信息发送给UE。该过程中，由于第一小小区基站的第一载波集，即MC集包含的载波为不被其他小小区基站干扰的载波，因此可以用于调度边缘UE，而第一小小区基站的第二载波集，即OC集包含的载波为可以灵活的激活或去激活的载波，因此可以调度中心UE，从而降低对UE的干扰。也就是说，当第二载波集中的载波为被配置有为ABS的载波时，可以相应调度边缘UE。此时，相邻的小小区基站通过基站间接口进行信令交互，从而根据载波索引(index)，完成对应载波上的ABS的协调。同时，由于UE只对第一载波集中的载波与第二载波集中的激活载波进行测量，因此可以减少UE对载波测量的复杂度。
下面，从具体如何发送测量资源限制信息的角度对本发明进行详细描述。
例如，当测量资源限制信息具体用于指示所述第一载波集时，第一小小区基站通过广播信令或无线资源控制RRC信令向所述UE发送所述测量资源限制信息。
具体的，第一小小区基站以半静态方式、通过所述广播信令或所述RRC信令向所述UE发送所述测量资源限制信息。
再如，当测量资源限制信息具体用于指示所述第二载波集时，第一小小区基站通过广播信令或专有信令向所述UE发送所述测量资源限制信息。
具体的，第一小小区基站以半静态或动态方式、通过广播信令或专有信令向所述UE发送所述测量资源限制信息。
另外，上述实施例中，第一小小区基站还获取测量结果，改测量结果指示第二小小区基站在第一载波上的负载和/或干扰，所述第一载波属于所述第二载波集；然后，第一小小区基站根据所述测量结果，生成指示信息，所述指示信息用于指示所述第一小小区基站激活和/或去激活所述第一载波；最后，所述第一小小区基站通过物理层信令向所述UE发送所述指示信息。 发送指示信息的过程中，第一小小区基站可以以半静态或动态的方式，通过物理层信令向UE发送该指示信息。
另外，上述实施例中，第一小小区基站向用户设备UE发送所述测量资源限制信息，包括：所述第一小小区基通过第二载波向所述UE发送所述测量资源限制信息，所述第二载波属于所述第一载波集。该过程中，对于任意一个小小区基站来说，MC集和OC集都可以在MC集中的一个载波，如MC集中的主载波或辅载波上的广播信令中统一指示。如此一来，可通过跨载波指示通知UE关于需要测量的载波。
另外，上述实施例中，UE对所述第一载波集中的载波和第二载波集中的激活载波进行测量，具体指：UE在所述第一载波集中的载波和第二载波集中的激活载波上进行无线资源管理(Radio Resource Management，RRM)测量和/或信道状态指示(Channel State Information，CSI)测量等。
图5为本发明第一小小区基站实施例一的结构示意图。本实施例提供的第一小小区基站是与图2对应的第一小小区基站，可以实现本发明任一实施例提供的应用于第一小小区基站的方法的各个步骤，具体实现过程在此不再赘述。具体的，本实施例提供的第一小小区基站包括：
处理器11，用于生成载波协调信息，所述载波协调信息用于指示所述第一小小区基站的第一载波集和/或第二载波集；
收发器12，用于向第二小小区基站发送所述载波协调信息，使得所述第二小小区基站根据所述载波协调信息，为自身配置第三载波集和/或第四载波集，所述第三载波集包含的各载波与所述第一载波集包含的各载波相互正交，所述第二载波集包含的各载波与所述第四载波集包含的各载波非正交。
本发明实施例提供的第一小小区基站，生成指示自身的第一载波集和/或第二载波集的载波协调信息，并将该载波协调信息发送给第二小小区基站，使得第二小小区基站根据该载波协调信息为自身配置第三载波集/和或第四载波集。该过程中，由于第二小小区基站为自身配置的第三载波聚包含的载波与第一小小区基站的第一载波集中的载波正交，使得第一小小区基站的第一载波集中的载波，与第二小小区基站的第三载波集中的载波互不干扰。也就是说，对于一个具体的小小区基站，其可根据其他小小区基站发送的载波协调信息为自身配置MC集与OC集，每个小小区基站都可以配置不被其他 小小区基站干扰的MC载波集和能够容忍一定程度干扰的OC载波集。如此一来，采用MC载波集中的载波调度边缘UE和/或中心UE，并根据OC载波集中的载波是否配置ABS来决定中心UE或边缘UE的调度，从而降低各小小区基站之间的干扰。
可选的，所述第一载波集、所述第二载波集、所述第三载波集与所述第四载波集至少满足下述条件之一：
所述第一载波集包含的各载波与第二载波集包含的各载波正交、所述第一载波集包含的各载波与第四载波集包含的各载波正交、所述第二载波集包含的各载波与所述第三载波集包含的各载波正交。
