图1示出了本发明实施例所涉及的通信系统的一种可能的结构示意图。如图1所示，该通信系统包括至少一个网络设备100(图1中仅示出一个)以及每个网络设备100所连接的一个或多个终端200。
其中，上述的网络设备100可以为基站、核心网设备、发射接收节点(Transmission and Reception Point，TRP)、中继站或接入点等。网络设备100可以是全球移动通信系统(Global System for Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)网络中的基站收发信台(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的NB(NodeB)，还可以是LTE中的eNB或eNodeB(evolutional NodeB)。网络设备100还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器。网络设备100还可以是5G通信系统中的网络设备或未来演进网络中的网络设备。然用词并不构成对本申请的限制。

下面对本申请中所涉及的部分术语进行解释，以方便读者理解：
1、跨载波调度
在相关技术中，在某些小区的信道质量不够好或者信道阻塞概率较高的情况下，网络设备可以为终端配置跨载波调度，即把控制信道配置在其他信道质量较好的小区(例如，主小区)，来跨载波调度其他小区(例如，辅小区)的数据。其中，如果某一小区被配置了控制信道PDCCH，则可以称该小区为调度小区(scheduling cell)。一般的，调度小区可以是自调度模式，即该小区只调度自己，也可以是跨载波调度模式，即该小区可以调度一个或多个自己以外的被调度小区(scheduled cell)。被调度小区没有自己的PDCCH，只能由跨载波调度配置指示的一个调度小区来调度。
需要说明的是，调度小区与被调度小区的子载波带宽(Subcarrier Spacing，SCS)可以相同或不同。
其中，终端支持的SCS配置μ如下表1所示，每一个μ值对应一个子载波间隔。

实施例一：
图2示出了本发明实施例提供的一种用于监听PDCCH的方法的流程示意图，如图2所示，该用于监听PDCCH的方法可以包括：
步骤201：网络设备为终端配置M个小区的小区参数。
相应的，对端终端接收网络设备向终端发送的小区参数。其中，上述的网络设备可以为图1所示通信系统中的网络设备，例如，基站；上述的第一终端可以为图1所示的通信系统中的终端设备。
步骤202：网络设备通过N个调度小区向终端发送PDCCH。
步骤203：终端根据N个调度小区的PDCCH盲检能力信息监听PDCCH。
在本发明实施例中，上述的M个小区包括：N个调度小区以及X个被调度小区，上述N个调度小区中的部分或全部调度小区配置有被调度小区，上述的X个被调度小区为该部分或全部调度小区对应的被调度小区。其中，上述的M、N为大于或等于1的正整数， X为大于或等于0的正整数，M＝N+X。
需要说明的是，本发明实施例中的被调度小区是指被配置了跨载波调度配置的小区。
在本发明实施例中，上述的小区参数用于指示终端根据N个调度小区的PDCCH盲检能力信息监听PDCCH。上述的小区参数与N个调度小区的PDCCH盲检能力信息有关。上述的N个调度小区的PDCCH盲检能力信息用于指示在单位时间内终端在每个调度小区或N个调度小区下对PDCCH进行盲检的最大处理能力。
在本发明实施例中，上述的最大处理能力包括：终端对PDCCH进行盲检测的最大PDCCH candidate数目(例如，表2中的PDCCH candidate数目)，以及终端对PDCCH进行盲检测所需的最大信道估计数，即不重叠的CCE的数目(例如，表3中的CCE数目)。
在本发明实施例中，终端在监听PDCCH时，会以PDCCH candidate为逻辑单位进行盲检测。终端盲检测这些PDCCH candidate，如果盲检测成功，说明这些PDCCH candidate是有效的PDCCH。如果不成功，说明这些PDCCH candidate是无效的(例如，是发给其他终端的，或是一堆无效噪声)。因此，终端监听PDCCH也可认为是监听PDCCH candidate。
可选的，在本发明实施例中，上述的小区参数包括以下至少一项：每个调度小区可调度的小区数量、每个小区的子载波间隔、每个小区的小区标识以及为所述终端配置的小区数量M。
在本发明实施例中，终端可以根据小区参数间接推断出终端对PDCCH进行盲检支持的最大处理能力，也可以直接根据终端上报的对PDCCH进行盲检支持的最大处理能力，来为N个调度小区或每个调度小区分配PDCCH盲检能力和/或搜索空间集和/或PDCCH candidate。
需要说明的是，网络设备通过N个调度小区向终端发送PDCCH时，也需要确定上述的N个调度小区的PDCCH盲检能力信息，以保证所发送的PDCCH，不会超过终端对PDCCH进行盲检支持的最大处理能力。
本发明实施例提供的用于监听PDCCH的方法，网络设备在跨载波调度过程中，通过为终端配置包含N个调度小区以及X个被调度小区的M个小区的小区参数，使得终端可以基于该小区参数，确定出终端在每个调度小区或N个调度小区对PDCCH进行盲检测的最大处理能力(即N个调度小区的PDCCH盲检能力信息)，充分利用了终端的处理能力，提高了终端监听PDCCH能效。
实施例二：
图3示出了本发明实施例提供的另一种用于监听PDCCH的方法的流程示意图，如图3所示，本发明实施例主要针对M个小区的子载波间隔相同的场景，在该场景下，该用于监听PDCCH的方法可以包括：
步骤301：网络设备为终端配置M个小区的小区参数。
步骤302：网络设备通过N个调度小区向终端发送PDCCH。
步骤303：终端在M个小区的子载波间隔相同的情况下，获取第一调度小区的第一待选PDCCH盲检能力信息以及第二待选PDCCH盲检能力信息，并将第一待选PDCCH盲检能力信息和第二待选PDCCH盲检能力信息中的最小值，作为第一调度小区的PDCCH盲检能力信息。
在本发明实施例中，终端基于上述的步骤303确定出每个调度小区的PDCCH盲检能力信息。
在本发明实施例中，上述的第一待选PDCCH盲检能力信息与以下至少一项相关：第一值、第一信息以及第一调度小区的子载波间隔对应的第二信息；上述的第二待选PDCCH盲检能力信息与以下至少一项相关：第一调度小区可调度的小区数量以及第二信息。
其中，上述的第一信息用于指示终端对PDCCH进行盲检支持的最大处理能力，即终端上报的对PDCCH进行盲检支持的最大处理能力。上述的第二信息用于指示第一调度小区对应的子载波间隔的配置下终端在单小区下对PDCCH进行盲检的最大处理能力，例如，表2中的PDCCH candidate数目，以及表3中的CCE数目。上述的第一调度小区为上述N个调度小区中的其中一个。上述的第一值为终端为第一调度小区分配PDCCH盲检能力的分配比例。
示例性的，每个调度小区的分配比例可以与小区参数相关，例如，与调度小区的小区数目N相关，与调度小区的小区ID相关，与被调度小区的小区ID相关等。
在一种示例中，上述的第一值为第一调度小区可调度的小区数量与网络设备为终端配置的小区数量M间的比值。
示例性的，假设终端配置了k个调度小区，每个调度小区调度的小区数(包括自己)为g k，则每个调度小区分配的最大处理能力为min{Rk,Sk}，其中，Rk根据实际配置或激活的小区数Tk确定(e.g.Rk＝P×T k)，Sk根据终端上报的对PDCCH进行盲检支持的最大处理能力Y确定(e.g.Sk＝floor{P×Y×f k})，P为单小区下UE的最大处理能力，f k为每个调度小区的分配比例。
步骤304：终端根据N个调度小区的PDCCH盲检能力信息监听PDCCH。
需要说明的是，本实施例二并不对上述的各步骤的先后顺序进行限定，上文中个步骤的执行顺序应以其功能和内在逻辑确定，即上述步骤的序号的大小不应对本发明实施例的实施过程构成任何限定。例如，上述的步骤303可以在步骤304之前执行，也可以在步骤304的执行过程中执行，本发明对此不作限定。
需要说明的是，本实施例二中与实施例一相同或相似的描述均可参照实施例一中的描述，本发明对此不再赘述。
举例说明，网络设备通过RRC为终端配置并激活了6个小区(即小区A、B、C、D、E、F)，其中小区A是主小区，小区B、C、D、E、F是辅小区，且小区A跨载波调度小区B、C、D，小区E和小区F是自调度小区。

需要说明的是，网络设备在通过N个调度小区向终端发送PDCCH时，也可以按照上述的步骤303所示的方式来确定出每个调度小区的PDCCH盲检能力信息，即网络设备在网络侧也可以执行上述的步骤303中的内容，具体可参见上述内容(即与步骤303相关的所有内容)，这里不再赘述。

需要说明的是，网络设备在通过N个调度小区向终端发送PDCCH时，也可以按照上述的步骤403所示的方式来确定出每个调度小区的PDCCH盲检能力信息，即网络设备在网络侧也可以执行上述的步骤403中的内容，具体可参见上述内容(即与步骤403相关的所有内容)，这里不再赘述。

步骤604：终端根据N个调度小区的PDCCH盲检能力信息监听PDCCH。
需要说明的是，本实施例五并不对上述的各步骤的先后顺序进行限定，上文中个步骤的执行顺序应以其功能和内在逻辑确定，即上述步骤的序号的大小不应对本实施例五的实施过程构成任何限定。例如，上述的步骤603可以在步骤604之前执行，也可以在步骤604的执行过程中执行，本发明对此不作限定。
需要说明的是，本实施例五中与实施例一至四中相同或相似的描述均可参照实施例一至四中的描述，本发明对此不再赘述。
需要说明的是，本发明实施例可以适用于任何跨载波调度场景(即，不仅适用于M个小区的子载波间隔相同的场景，也适用于M个小区的子载波间隔不相同的场景)。

本发明实施例提供的用于监听PDCCH的方法，网络设备在跨载波调度过程中，通过为终端配置包含N个调度小区以及X个被调度小区的M个小区的小区参数，使得终端可以基于该小区参数，确定出终端在N个调度小区对PDCCH进行盲检测的最大处理能力(即N个调度小区的总PDCCH盲检能力信息)，充分利用了终端的处理能力，提高了终端监听PDCCH能效。
实施例六：
图7示出了本发明实施例提供的另一种用于监听PDCCH的方法的流程示意图，如图7所示，该用于监听PDCCH的方法包括如下步骤：
步骤701：终端获取第五信息。
其中，上述的第五信息用于指示所述终端在所述N个调度小区的所有搜索空间集下对PDCCH进行监听的数量。
可选的，在本发明实施例中，该方法还包括如下步骤：
步骤701a：终端接收到网络设备发送的配置信息。
其中，上述的第五信息与该配置信息有关，即终端基于该配置信息可以确定出上述的第五信息。上述的配置信息包括以下至少一项：每个调度小区对应PDCCH盲检的时频域资源信息、每个调度小区关联的搜索空间集以及每个搜索空间集对应的第四信息；其中，上述的第四信息用于指示终端在所述搜索空间集下对PDCCH进行监听的数量。
步骤702：当终端根据第五信息确定终端在N个调度小区的所有搜索空间集下对PDCCH进行监听的数量超过了终端对PDCCH进行盲检支持的最大处理能力，则终端不分配第三调度小区的部分搜索空间集，或者，为第三调度小区的部分搜索空间集分配部分PDCCH盲检能力。
其中，上述的第三调度小区为N个调度小区中的其中一个，且第三调度小区对应 至少一个被调度小区。
在本发明实施例中，在调度小区被配置跨载波调度其他小区的情况(即调度小区对应至少一个被调度小区)下，该调度小区可以被超订(overbooking)，即允许配置的搜索空间集的处理能力超过终端对PDCCH进行盲检支持的最大处理能力。在没有配置跨载波调度的辅小区不允许被超订，即配置的搜索空间集的处理能力不能超过最大处理能力。
示例性的，终端实际分配搜索空间集时，可以根据每个搜索空间集对应的以下至少一个信息(例如，搜索空间集的ID，周期，PDCCH candidate数目，符号数，监听的DCI格式等)，对搜索空间集进行排序，按照排序顺序分配或丢弃搜索空间集，当需求的处理能力超过最大处理能力时，停止分配并丢弃所有剩余的搜索空间集。
示例性的，对于PDCCH candidate，终端可以每个PDCCH candidate对应的以下至少一个信息(例如，CIF值，聚合等级，小区ID或index，CCE坐标等)，对PDCCH candidate进行排序，按照排序顺序分配或丢弃PDCCH candidate。
举例说明，网络设备通过RRC为终端配置并激活了6个小区(即小区A、B、C、D、E、F)，其中小区A是主小区，小区B、C、D、E、F是辅小区，且小区B跨载波调度小区C、D、E，小区A、小区F是自调度小区。
具体的，网络设备配置上述小区的小区ID，Index，CIF值等。小区A、B、C、D、E、F的index分别是0、1、2、3、4、5。B、C、D、E在B上对应的CIF分别是0、2、3、1。所有小区的BWP的SCS为15kHz。终端上报其最大的CA盲检测处理能力为4。
具体的，网络设备配置了A、B、F(调度小区)的BWP上的PDCCH，包括CORESET以及关联的搜索空间集，且对小区B的PDCCH candidate数目进行overbooking。其中，小区A上CSS的PDCCH candidate数目为7，USS的PDCCH candidate数目为32；小区B上的USS1、USS2、USS3、USS4的PDCCH candidate数目均为32；小区F上的USS的PDCCH candidate数目为32。
由于终端可以在多个调度小区间动态共享最大的PDCCH candidate数目，因此，基于上述内容，可计算出终端的所有调度小区的所有搜索空间集的PDCCH candidate数目(7+32*6＝199)，即终端的所有调度小区的处理需求，由于终端支持的最大PDCCH candidate数目(44*4＝176)小于199，因此，网络设备可以选择一个仅对自身进行调度的调度小区对其处理能力进行限制，即该小区配置的搜索空间集的处理能力不能超过该小区的最大处理能力。例如，由于网络侧对小区B进行了overbooking，因此，终端可以选择丢弃小区B的部分PDCCH candidate，如，不分配小区B上的USS4，从而保证终端的所有调度小区的需要的最大PDCCH candidate数目(7+32*5＝167)小于终端支持的最大PDCCH candidate数目(44*4＝176)。
同理，可以确定出最大的不重叠的CCE数目的分配。
需要说明的是，网络设备在网络侧也可以执行上述的步骤701和步骤702中的内容，这里不再赘述。
本发明实施例提供的用于监听PDCCH的方法，在N个调度小区的处理需求大于终端支持的最大处理能力的场景下，通过限制仅对自身进行调度的调度小区的处理能 力，从而确保终端为N个调度小区分配的最大处理能力不超过终端支持的最大处理能力。
