下行信道的检测方法、信息的配置方法、终端及网络设备
相关申请的交叉引用
本申请主张在2019年5月10日在中国提交的中国专利申请号No.201910389376.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种下行信道的检测方法、信息的配置方法、终端及网络设备。
背景技术
在目前5G系统中，搜索空间包含的PDCCH(物理下行控制信道)candidate(候选)数目、聚合等级以及监听周期均可由网络侧进行配置。在一个active BWP(激活的带宽部分)内，最多支持10个不同的搜索空间。终端接收到网络侧的相关配置后，需要按照配置的SS(搜索空间)周期在对应的搜索空间内检测下行控制信道。也即终端按照希望接收的DCI format(下行控制信息格式)，在搜索空间的每个PDCCH candidate上尝试检测DCI。
在5G移动通信系统中，为了支持不同类型的业务，终端需要非常密集的检测接收下行控制信道。频繁的检测接收下行控制信道无疑会增加终端侧的复杂度，并极大的增加终端侧耗电。网络侧可以通过配置的方式，减少搜索空间大小以及增大搜索空间监听周期。由于业务到达的不确定性，基站并不会在每个配置的搜索空间对应的监听位置上发送PDCCH，且高层信令配置周期较长，会降低网络侧调度灵活性。另外，终端侧需要始终按照配置进行监听，从而增加了终端侧耗电。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示，本公开的实施例提供一种下行信道的检测方法，应用于终端，所述方法包括：
步骤11，获得终端的DCI(下行控制信息)传输所在的资源位置与下行控制信道的检测方式的对应关系；这里，可以通过高层信令或者预定义的方式，获得所述终端的DCI传输所在的资源位置与下行控制信道的检测方式的对应关系。这里的高层信令，如RRC(无线资源控制)信令，但不限于RRC 信令；
步骤12，根据所述资源位置与下行控制信道的检测方式的对应关系，检测下行控制信道。
本公开的该实施例，通过获得终端的DCI传输所在的资源位置与下行控制信道的检测方式的对应关系；根据所述资源位置与下行控制信道的检测方式的对应关系，检测后续下行控制信道。可以避免在DCI中定义新的信息域，减少终端对下行控制信道盲检的复杂度，降低终端的耗电。
本公开的一实施例中，所述资源位置与下行控制信道的检测方式的对应关系包括以下至少一项：
1)SS(搜索空间)ID与下行控制信道检测方式之间的对应关系；
2)CORESET(控制资源集)ID与下行控制信道检测方式之间的对应关系。
本公开的一实施例中，搜索空间ID与下行控制信道检测方式之间存在对应关系时，上述步骤12的一种实现方式包括：
步骤121，如果终端在配置的搜索空间#n内检测到调度数据传输的下行控制信息DCI，则终端在完成所述数据传输后，只在所述搜索空间#n内检测下行控制信道；
步骤122，终端再次在所述搜索空间#n内检测到调度数据传输的DCI之后，所述终端在所有配置的搜索空间内检测下行控制信道；n为大于或者等于0的整数。
步骤123，终端再次在所述搜索空间#n内检测到调度数据传输的DCI之后，只在所述搜索空间#n内检测下行控制信道；并以此类推。
比如，如图2所示，假设网络设备(如基站)为终端配置了M＝3个搜索空间{SS#1SS#2SS#3}，且具有不同的监听周期，例如SS#1的监听周期为T1＝5，SS#1的监听周期为T2＝1，SS#1的监听周期为T3＝2。基站通过RRC信令通知终端，SS#1用于指示下行控制信道的跳过信息。也即如果终端在SS#1内检测接收到对应的调度信息，则终端确定对应的下行控制信道跳过行为。例如终端在SS#1内第一次检测接收到DCI，则终端在检测接收到所述DCI后，不再检测SS#2以及SS#3，只在SS#1内检测接收下行控制信道；后 续的，如果终端在SS#1内再次检测接收到DCI，则从该时刻开始检测所有的配置搜索空间，也即{SS#1SS#2SS#3}。这样终端不再频繁检测下行控制信道，可以降低耗电，减少终端盲检的复杂度。
对于基站侧，为了保证与终端侧相同的理解，需要在接收到终端发送了明确的ACK/NACK之后执行相应的行为。例如，针对于DCI和对应的数据信道，基站侧在检测接收到ACK/NACK后认为下行控制信道的监听行为发生了反转。例如基站收到了在SS#1内发送DCI调度的数据信道的第一个ACK/NACK之后，确定在后续时间段内只会在SS#1内发送下行控制信道，而不会SS#2以及SS#3内发送下行控制信道；基站收到了在SS#1内发送DCI调度的数据信道的第二个有效ACK/NACK之后，确定在后续时间段内可以在SS#1/SS#2/SS#3内发送下行控制信道。并以此类推。由此可见，基站只会在需要变更下行控制信道监听行为时在SS#1中传输DCI。
本公开的一实施例中，控制资源集CORESET ID与下行控制信道检测方式之间存在对应关系时，上述步骤12的另一种实现方式包括：
步骤221，如果终端在配置的CORESET#m内检测接收到调度数据传输的下行控制信息DCI，则终端在完成所述数据传输后，在所述CORESET#m内配置的搜索空间中检测下行控制信道；所述CORESET#m用于指示下行控制信道的跳过信息；
步骤222，终端再次在所述CORESET#m内检测到调度数据传输的DCI之后，终端在所有配置的搜索空间内检测下行控制信道；m为大于或者等于0的整数；
步骤223，终端再次在所述CORESET#m内检测到调度数据传输的DCI之后，只在所述CORESET#m内检测下行控制信道；并以此类推。
比如，如图3所示，基站可以通过高层信令配置用于指示下行控制信道跳过信息的CORESET ID。需要注意的是，一个CORESET可以配置多个搜索空间。例如基站为终端配置了两个CORESET{CORESET#1CORESET#2}，且CORESET#1用于指示下行控制信道的跳过信息。例如终端在CORESET#1内第一次检测接收到DCI，则终端在检测接收到所述DCI后，不再从CORESET#2内检测接收下行控制信道，只在CORESET#1内检测接收下行控 制信道；后续的，如果终端在CORESET#1内再次检测接收到DCI，则从该时刻开始检测所有CORESET内的下行控制信道。这样终端不再频繁检测下行控制信道，可以降低耗电，减少终端盲检的复杂度。需要注意的是，每个CORESET内可以配置多个关联的搜索空间，此时，终端在CORESET#1内的至少一个搜索空间内第一次检测接收到DCI，则终端在检测接收到所述DCI后，不再从CORESET#2内检测接收下行控制信道，只在CORESET#1内检测接收下行控制信道。
本公开的一实施例中，上述步骤12的又一种实现方式包括：
步骤331，终端在预设搜索空间或者预设CORESET内检测并接收到下行控制信息并完成对应的数据传输过程之后，在T1个时间单元内不再检测下行控制信道或者只在所述预设搜索空间或者预设CORESET内检测下行控制信道；T1为大于或者等于1的整数，T1通过高层信令进行配置或者通过预定义的方式确定。
比如，网络侧通过高层信令(RRC signaling)配置用于携带下行控制信道跳过信息的搜索空间ID或者CORESET ID。终端在所述搜索空间或者CORESET内检测接收到调度信息后，在接下来的T1时间段内不再监听任何下行控制信道，或者只在所述特定搜索空间/CORESET内监听下行控制信道。所述时间T1通过高层信令进行配置，例如RRC信令。
本公开的一实施例中，搜索空间ID与下行控制信道检测方式之间存在对应关系时，上述步骤12的再一种实现方式包括：
步骤441，在预设搜索空间内的目标物理下行控制信道PDCCH候选的编号上检测到调度数据传输的物理下行控制信道，根据所述PDCCH候选的编号与预设跳过信息的对应关系，检测下行控制信道。
可选的，终端在所述预设搜索空间的预设聚合等级(AL)下的PDCCH候选编号#L检测到调度数据传输的下行控制信息DCI，则所述终端在完成所述调度数据传输后的目标时长内不再检测下行控制信道；L为大于或者等于0的整数，所述目标时长包括分别与一个PDCCH候选编号对应的T2个时隙，T2为大于或者等于1的整数；或者，所述目标时长作用于一个PDCCH候选编号对应的至少一个搜索空间。
比如，基站通过RRC信令指定用于指示下行控制信道跳过信息的搜索空间ID。并且，通知搜索空间内每个聚合等级下PDCCH candidate index(候选编号的索引)与PDCCH监听跳过时间段的对应关系。例如所述搜索空间具有4个聚合等级{AL1 AL2 AL4 AL8},并假设跳过时间段有两种{T21，T22},则在每个聚合等级下的PDCCH candidate index与PDCCH监听跳过时间段的对应关系如下表所示，当然，该表格仅是本公开的该实施例中的一种实例，并不用于限定该实施例的范围；
Figure PCTCN2020086102-appb-000001
基站侧根据终端侧节电的需求，选择在特定AL下用于传输PDCCH的PDCCH candidate index，PDCCH candidate index并不限于上述0和1，还可以包括更多的PDCCH candidate index。需要注意的是，如果终端在基站侧指定的搜索空间内没有检测接收到任何DCI，则终端需要在所有配置的搜索空间内监听下行控制信道。
本公开的上述实施例中，终端检测接收到调度信息的搜索空间、CORESET、PDCCH candidate index、T1、T2(T21或者T22)中的全部或者部分也可以通过预定义的方式确定。
本公开的上述实施例中，通过隐式的方式确定PDCCH监听跳过时间段，终端根据定义好的规则确定跳过部分搜索空间的监听，可以避免在DCI中定义新的信息域，减少终端盲检的复杂度，降低终端的耗电。
进一步的，基站通过高层信令(RRC信令)配置或者协议预定义的方式 确定PDCCH candidate与所需跳过搜索空间ID之间的对应关系，基站侧和终端侧根据传输PDCCH的candidate编号确定相应的跳过行为。一个例子如下表所示，注意的是，一个PDCCH candidate编号可对应于一组搜索空间。假设基站配置了3个SS，并在SS#1内携带所述下行控制信道跳过信息。
