为便于理解本申请实施例的技术方案，以下对本申请实施例涉及到的相关技术进行说明。
在支持跨载波调度的终端中，网路通过在每个serving cell上配置CrossCarrierSchedulingConfig来支持终端在该serving cell是自调度还是被别的小区调度。如果该serving cell是自调度，则终端在当前serving cell上配置的搜索空间(search space)上检测物理下行控制信道(PDCCH，Physical Downlink Control Channel)；如果该serving cell是跨载波调度，则终端在调度小区(scheduling cell，指调度当前serving cell的小区)上配置的search space上检测PDCCH。
在相关技术中，支持跨载波调度的终端通过以下方式确定每一个scheduled cell在scheduling cell的search space中对应的PDCCH盲检次：在search space配置结构中，每个search space可以配置不同的聚合等级，不同的聚合等级对应一个盲检次数。这种配置方式让终端对于所有的scheduling cell和scheduled cell对于某一个聚合等级采用相同的盲检次数，而不能达到不同的小区有不同的盲检次数。比如，有1个scheduling cell，两个scheduled cell(scheduled cell1和scheduled cell2)，假设scheduling cell上配置的一个search space的控制信道单元(CCE，Control Channel Element)为32个，假设对于聚合等级为2的情况下，想要实现scheduling cell的盲检次数为2，scheduled cell1为3，scheduled cell2为4，目前的信令配置无法达到这种需求。另一方面，在search space配置中，一个serving cell可以配置多个带宽部分(BWP，Band Width Part)，每个BWP上最多可以配置3个控制资源集(CORESET)，10个search space。本申请实施例可以实现跨载波调度中不同小区具有不同的盲检次数。
图2为本申请实施例提供的盲检次数的确定方法的流程示意图，如图2所示，所述盲检次数的确定方法包括以下步骤：
步骤201：终端在第一小区的第一搜索空间上盲检下行控制信道，所述下行控制信道用于调度第二小区，其中，所述下行控制信道的盲检次数基于所述第二小区的第二搜索空间的配置信息和/或所述第一小区的第一搜索空间的配置信息确定。
本申请实施例中，所述终端可以是手机、车载终端、平板电脑、笔记本、穿戴式设备等任意能够与网络进行通信的设备。
本申请实施例中，第一小区的描述也可以替换为第一载波，第二小区的描述也可以替换为第二载波，在跨载波调度中，第一小区为scheduling cell(即调度载波)，第二小区为scheduled cell(即被调度载波)。在实现跨载波调度时，所述终端在第一小区的第一搜索空间上盲检下行控制信道，所述下行控制信道用于调度第二小区。
举个例子：小区1为scheduling cell，小区2为scheduled cell，小区1上的PDCCH调度小区 2上的上行数据和/或下行数据；终端为了对小区2上数据进行接收，需要从小区1上获取PDCCH，从而基于该PDCCH确定小区2上的数据的时频资源等信息。
本申请实施例中，调度第二小区的下行控制信道(如PDCCH)在第一小区的第一搜索空间中传输，调度第二小区的下行控制信道的盲检次数(简称为第二小区的盲检次数)基于所述第二小区的第二搜索空间的配置信息和/或所述第一小区的第一搜索空间的配置信息确定。以下对第二小区的盲检次数何时基于第二小区的第二搜索空间的配置信息确定，何时基于第一小区的第一搜索空间的配置信息确定，进行描述。
所述终端向网络上报第一指示信息，所述第一指示信息用于指示所述终端是否支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置。其中，1)如果所述第一指示信息指示所述终端支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置，则：所述终端基于所述第二小区的第二搜索空间的配置信息确定所述下行控制信道的盲检次数。2)如果所述第一指示信息指示所述终端不支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置，则：所述终端基于所述第一小区的第一搜索空间的配置信息确定所述下行控制信道的盲检次数。
上述方案中，所述第一指示信息可以是是显示指示也可以是隐式指示。
在一实施方式中(显示指示)，所述第一指示信息为所述终端的UE能力信息，所述终端的UE能力信息指示所述终端是否支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置。
在另一实施方式中(隐式指示)，所述第一指示信息为所述终端的接入层(AS，Access Stratum)版本信息，所述终端的AS版本信息用于所述网络确定所述终端是否支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置。例如：终端的AS版本为R15，则表示该终端不支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置；终端的AS版本为R16，则表示该终端支持跨载波调度以及在跨载波调度中不同载波具有不同盲检次数的配置。
上述方案中，所述第一小区配置有至少一个BWP，每个BWP上配置有至少一个搜索空间，每个搜索空间配置有至少一个聚合等级，每个聚合等级对应一个盲检次数。同样，对于支持跨载波调度的终端，所述第二小区配置有至少一个BWP，每个BWP上配置有至少一个搜索空间，每个搜索空间配置有至少一个聚合等级，每个聚合等级对应一个盲检次数。
举个例子，所述第一小区配置有3个BWP，分别为BWP1、BWP2，BWP3，其中，BWP1为激活的BWP。这3个BWP中的每个BWP都配置有至少一个搜索空间，以BWP1为例，BWP1上配置有第一搜索空间，该第一搜索空间的配置包括如下信息：第一搜索空间的搜索空间标识(SearchSpaceId)、第一搜索空间关联的第一控制资源集的控制资源集标识(ControlResourceSetId)、第一搜索空间的时域信息(周期信息、在一个周期中的起始位置信息)；此外，该第一搜索空间的配置还包括如下信息：一个或多个聚合等级，其中，每个聚合等级对应一个盲检次数。第二小区上的BWP配置以及搜索空间配置与第一小区同理。
基于此，终端在第一小区的第一搜索空间上盲检调度第二小区的下行控制信道时，下行控制信道的盲检次数是基于第二小区的第二搜索空间的配置信息中的盲检次数确定的。换言之，将第二小区的第二搜索空间的配置信息中的聚合等级及对应的盲检次数的相关配置替换掉第一小区的第一搜索空间的聚合等级及对应的盲检次数的相关配置，就得到了第二小区的PDCCH盲检空间配置。需要注意的是，盲检次数是针对特定聚合等级的，例如聚合等级1的盲检次数为N1，聚合等级2的盲检次数为N2。
本申请实施例中，所述第一搜索空间为所述第一小区当前激活的BWP上的一个搜索空间，所述第二搜索空间为所述第二小区当前激活的BWP上的一个搜索空间；其中，所述第一搜索空间和所述第二搜索空间具有对应关系，即所述第一搜索空间的标识和所述第二搜索空间的标识具有对应关系。进一步，所述第一搜索空间和所述第二搜索空间的对应关系，通过以下方式之一确定：
方式一：将所述第二小区当前激活的BWP上的搜索空间按照标识由小到大的顺序对应到所述第一小区当前激活的BWP上的搜索空间。
其中，所述第一小区当前激活的BWP上的搜索空间的个数大于等于所述第二小区当前激活的BWP上的搜索空间的个数，从而使得第二小区的第二搜索空间能够唯一对应到第一小区的第一搜索空间上。

方式二：将所述第二小区当前激活的BWP上的搜索空间按照标识由大到小的顺序对应到所述第一小区当前激活的BWP上的搜索空间。
其中，所述第一小区当前激活的BWP上的搜索空间的个数大于等于所述第二小区当前激活的BWP上的搜索空间的个数，从而使得第二小区的第二搜索空间能够唯一对应到第一小区的第一搜索空间上。
举个例子：参照图3(b)，第一小区配置有3个BWP，分别为BWP#1，BWP#2和BWP#3，其中，BWP#1为当前激活的BWP，第二小区也配置有3个BWP，其中，BWP#2为当前激活的BWP。 第一小区的激活的BWP#1上配置有3个搜索空间，分别为搜索空间#1，搜索空间#4和搜索空间#6；第二小区的激活的BWP#2上配置有3个搜索空间，分别为搜索空间#10，搜索空间#9和搜索空间#3。按照标识由大到小的顺序对应，第二小区的BWP#2上的搜索空间#10对应到第一小区的BWP#1上的搜索空间#1，第二小区的BWP#2上的搜索空间#9对应到第一小区的BWP#1上的搜索空间#4，第二小区的BWP#2上的搜索空间#3对应到第一小区的BWP#1上的搜索空间#6。

方式三：将所述第二小区当前激活的BWP上的搜索空间按照标识取模的方式对应到所述第一小区当前激活的BWP上的搜索空间。
其中，所述第一小区当前激活的BWP上的搜索空间的个数大于等于所述第二小区当前激活的BWP上的搜索空间的个数，从而使得第二小区的第二搜索空间能够唯一对应到第一小区的第一搜索空间上。
举个例子：参照图3(c)，第一小区配置有3个BWP，分别为BWP#1，BWP#2和BWP#3，其中，BWP#1为当前激活的BWP，第二小区也配置有3个BWP，其中，BWP#2为当前激活的BWP。第一小区的激活的BWP#1上配置有3个搜索空间，分别为搜索空间#1，搜索空间#5和搜索空间#6；第二小区的激活的BWP#2上配置有3个搜索空间，分别为搜索空间#10，搜索空间#5和搜索空间#3。按照对3做取模运算的结果对应，第二小区的BWP#2上的搜索空间#10对应到第一小区的BWP#1上的搜索空间#1(对3做取模运算的结果为1)，第二小区的BWP#2上的搜索空间#5对应到第一小区的BWP#1上的搜索空间#5(对3做取模运算的结果为2)，第二小区的BWP#2上的搜索空间#3对应到第一小区的BWP#1上的搜索空间#6(对3做取模运算的结果为0)。
基于此，以第二搜索空间是第二小区的BWP#2上的搜索空间#10为例，终端在第一小区的BWP#1上的搜索空间#1上盲检调度第二小区的PDCCH时，该PDCCH的盲检次数是第二小区的BWP#2上的搜索空间#10上配置的盲检次数，该PDCCH对应的其他搜索空间配置信息依然采用第一小区的BWP#1上的搜索空间#1的配置。
方式四：将所述第二小区当前激活的BWP上的搜索空间按照标识相同的方式对应到所述第一小区当前激活的BWP上的搜索空间。
其中，所述第一小区当前激活的BWP上的搜索空间的个数大于等于所述第二小区当前激活的BWP上的搜索空间的个数，从而使得第二小区的第二搜索空间能够唯一对应到第一小区的第一搜索空间上。
举个例子：参照图3(d)，第一小区配置有3个BWP，分别为BWP#1，BWP#2和BWP#3，其中，BWP#1为当前激活的BWP，第二小区也配置有3个BWP，其中，BWP#2为当前激活的BWP。第一小区的激活的BWP#1上配置有3个搜索空间，分别为搜索空间#3，搜索空间#9和搜索空间#10； 第二小区的激活的BWP#2上配置有3个搜索空间，分别为搜索空间#3，搜索空间#9和搜索空间#10。按照标识相同对应，第二小区的BWP#2上的搜索空间#3对应到第一小区的BWP#1上的搜索空间#3，第二小区的BWP#2上的搜索空间#9对应到第一小区的BWP#1上的搜索空间#9，第二小区的BWP#2上的搜索空间#10对应到第一小区的BWP#1上的搜索空间#10。
基于此，以第二搜索空间是第二小区的BWP#2上的搜索空间#3为例，终端在第一小区的BWP#1上的搜索空间#3上盲检调度第二小区的PDCCH时，该PDCCH的盲检次数是第二小区的BWP#2上的搜索空间#3上配置的盲检次数，该PDCCH对应的其他搜索空间配置信息依然采用第一小区的BWP#1上的搜索空间#3的配置。
方式五：按照网络配置的标识对应关系，将所述第二小区当前激活的BWP上的搜索空间对应到所述第一小区当前激活的BWP上的搜索空间。
其中，所述第一小区当前激活的BWP上的搜索空间的个数大于等于所述第二小区当前激活的BWP上的搜索空间的个数，从而使得第二小区的第二搜索空间能够唯一对应到第一小区的第一搜索空间上。
这里，网络可以预先配置第一小区和第二小区的各个搜索空间之间的对应关系，终端直接依据该对应关系来确定第一搜索空间与第二搜索空间的对应关系。
方式六：将所述第二小区当前激活的BWP上的搜索空间所对应的第一控制资源集对应到所述第一小区当前激活的BWP上的第二控制资源集，所述第一控制资源集和所述第二控制资源集具有相同的标识；其中，所述第二小区当前激活的BWP上的搜索空间的标识至少与所述第二控制资源集关联的一个搜索空间的标识相同；或者，将所述第二小区当前激活的BWP上的搜索空间中的至少一个参数应用到与所述第二控制资源集关联的至少一个搜索空间。
举个例子：参照图3(e)和图3(f)，搜索空间#1(Cell2)是第二小区当前激活的BWP上的一个搜索空间，与搜索空间#1(Cell2)关联的控制资源集是控制资源集2(Cell2)，将该控制资源集2(Cell2)对应到第一小区的控制资源集2(Cell1)，进一步，1)控制资源集2(Cell1)关联的搜索空间中如果有搜索空间#1(Cell1)，则将搜索空间#1(Cell2)对应到搜索空间#1(Cell1)，参照图3(e)。或者，2)控制资源集2(Cell1)关联的搜索空间中如果没有搜索空间#1(Cell1)，则按照预设规则将搜索空间#1(Cell2)对应到搜索空间#3(Cell1)，其中，搜索空间#3(Cell1)与控制资源集2(Cell1)关联，参照图3(f)。
基于此，终端在搜索空间#1(Cell1)或搜索空间#3(Cell1)上盲检调度第二小区的PDCCH时，该PDCCH的盲检次数是搜索空间#1(Cell2)上配置的盲检次数，该PDCCH对应的其他搜索空间配置信息依然采用搜索空间#1(Cell1)或搜索空间#3(Cell1)的配置。
本申请实施例中，所述第一搜索空间为所述第一小区当前激活的BWP上的一个搜索空间，所述第二搜索空间为所述第二小区非激活的BWP上的一个搜索空间；其中，所述第一搜索空间和所述第二搜索空间具有对应关系，即所述第一搜索空间的标识和所述第二搜索空间的标识具有对应关系。进一步，所述第一搜索空间和所述第二搜索空间具有相同的标识。
举个例子：第一小区配置有3个BWP，分别为BWP#1，BWP#2和BWP#3，其中，BWP#1为当前激活的BWP，第二小区也配置有3个BWP，其中，BWP#2为当前激活的BWP。第一小区的激活的BWP#1上配置有3个搜索空间，分别为搜索空间#1，搜索空间#2和搜索空间#3；第二小区的激活的BWP#2上配置有2个搜索空间，分别为搜索空间#4和搜索空间#5。假设第一搜索空间为第一小区激活的BWP#1上的搜索空间#2，由于第二小区激活的BWP#2上没有与搜索空间#2的标识一致的搜索空间，因此终端会在第二小区非激活的BWP上找跟第一小区激活的BWP#1上的搜索空间#2的标识一致的搜索空间，假设在第二小区非激活的BWP#1上有搜索空间#2，那么，终端将第二小区非激活的BWP#1上的搜索空间#2的相关参数(聚合等级以及对应的盲检次数)替换掉第一小区激活的BWP#1上的搜索空间#2的相关参数(聚合等级以及对应的盲检次数)。
需要说明的是，本申请实施例的技术方案中，第一小区调度的第二小区的数目为一个或多个，当第一小区调度的第二小区的数目为多个时，不同的第二小区对应的PDCCH盲检次数可以都不相同，从而实现了跨载波调度中不同小区具有不同的盲检次数。
