为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例提供了一种信号监听方法，如图2-1所示，包括：
步骤21：终端设备在非连续接收DRX ON时间段之前、且在监听起始时刻之后，在监听时间段中监听节能信号PDCCH；
其中，所述监听时间段由K个节能信号搜索空间中每一个节能信号搜索空间的至少一个配置参数确定；K为大于等于1的整数。
相应的，本发明实施例还提供一种信号发送方法，如图2-2所示，所述方法包括：
步骤31：网络设备在非连续接收DRX ON时间段之前、且在监听起始时刻之后，在监听时间段中发送节能信号物理下行控制信道PDCCH；
其中，所述监听时间段由K个节能信号搜索空间中每一个节能信号搜索空间的至少一个配置参数确定；K为大于等于1的整数。
所述节能信号搜索空间，也就是PDCCH Search Space。具体的，在新无线(NR)中，终端设备的下行物理控制信道(PDCCH，Physical Downlink Control CHannel)监听是在PDCCH搜索空间(search space)中进行的。PDCCH search space的配置参数一般由网络设备通过RRC信令通知终端设备。
关于节能信号PDCCH的相关说明，所述节能信号PDCCH除了可以用于唤醒终端 设备检测PDCCH，还可以用于指示终端设备唤醒时所使用的目标BWP(Bandwidth part，带宽部分)、所使用的PDCCH search space(搜索空间)的配置，辅小区的休眠(scell dormancy)指示信息等节能指示信息。
其中，所述节能信号为承载于PDCCH中的下行控制信息(Downlink Control Information，DCI)。例如，该节能信号为DCI格式(format)3_0。
需要说明的是，采用PDCCH承载节能信号具有如下一些优势：
1.可以直接复用PDCCH设计，包括编码、加扰、资源映射、搜索空间、控制资源集(Control Resource Set，CORESET)等方面，因此标准化的工作量较小；
2.与其他信号传输具有良好的兼容于复用特性，由于系统已经支持PDCCH信道，因此PDCCH与其他各信道如物理下行共享信道(Physical Downlink Shared Channel，PDSCH)等具有良好的兼容于复用特性。
关于监听起始时刻，可以为：所述终端设备基于配置的节能(PS，Power Saving)-偏置Offset、以及所述DRX ON时间段的起始时刻，确定所述监听起始时刻。
具体来说，配置的PS-Offset可以为网络设备通过RRC信令为终端设备配置的；当然，还可以为预定义的。基于DRX ON时间段的起始时刻以及PS-Offset确定监听起始时刻，具体可以为从DRX ON时间段的起始时刻减去PS-Offset之后得到的时刻作为所述监听起始时刻。
比如，参见图3-1所示，以图中左边一个DRX ON为例，将该DRX ON时段的起始时刻作为基准时刻，减去一个PS-Offset得到PDCCH监听时间段的监听起始时刻。
DRX ON时间段为终端在DRX周期的起始位置启动DRX“ON duration”定时器，从所述定时器启动时刻至所述定时器结束或超时时刻之间的时间段。比如，可以参见图3-1，其中方块中示意出一个DRX ON在时间轴上的覆盖范围可以为DRX ON时间段。
本实施例可以应用于终端设备被配置一个节能信号搜索空间的场景中，也可以应用于终端设备被配置多个节能信号搜索空间的场景中，下面结合多种示例对本实施例提供的方案进行说明：
示例1、K＝1，也就是终端设备被配置一个节能信号搜索空间的情况。
本示例中，所述监听时间段，包含：K个节能信号搜索空间中每一个节能信号搜索空间的M个持续时长；M为大于等于1的整数。
由于本示例针对K＝1的场景，因此，本示例的监听时间段中包含有针对配置的节能信号搜索空间的M个持续时长。
前述M可以为配置的、或者可以为预定义的；其中M为配置的情况中，可以为终端设备接收网络设备为其配置的M，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该M值。优选的，M＝1。
还需要指出的是，本示例中，监听时间段中包含M个持续时长，可以为监听时间段的长度等于M个持续时长之和；又或者，可以为监听时间段长度大于M个持续时长之和，这种情况，可以认为是监听时间段除了包含每一个持续时长的长度之外，还可以包含有相邻持续时长之间的间隔，或者，可以包含有持续时长之外的其他时长等。
所述M个持续时长中的每一个持续时长中，包含：至少一个监听时刻。
所述终端设备可以基于节能信号搜索空间的至少一个配置参数，来确定对应的监听时间段。其中，所述节能信号搜索空间，也就是PDCCH search space中所述至少一个配置参数，可以包括以下至少之一：
用于指示在对应的节能信号搜索空间的周期内连续监听的时隙个数的第一参数；
用于指示在对应的节能信号搜索空间中节能信号PDCCH监听时刻的起始符号的第二参数。
这里，所述第一参数可以为PDCCH Search Space中的“Duration”参数，第二参数可以为PDCCH Search Space中的“monitoringSymbolsWithinSlot”参数。
比如，可以基于第一参数来确定一个持续时长的长度；第二参数可以用于确定从哪个起始符号开始进行监听。
具体来说，通过第一参数可以确定每一个持续时长包含多个时隙；第二参数可以包含有bitmap(比特图)，该比特图可以指示每一个监听时刻的起始符号，换句话说，监听时刻有多少个可以通过bitmap来确定的；比如，bitmap指示“1001001”，那么可以认为从第一个符号起为一个监听时刻，第四个符号也为一监听时刻的起始符号，第7个符号也为一监听时刻的起始符号。再进一步地，可以通过CORESET来确定每一个起始符号对应多少个监听时刻，比如，第一个起始符号起两个监听时刻，第4个符号起两个监听时刻等等。
还需要指出的是，节能信号搜索空间中的配置参数，除了上述第一参数以及第二参数之外，还可以存在其他参数，比如，可以包括：搜索标识(search ID)；controlResourceSetId，用于指示控制资源集合(control resource set)的配置的ID，配置PDCCH search space的时频资源；监听的slot的周期以及在周期内的偏置；PDCCH候选candidates的配置信息；搜索空间(Search space)的类型指示，搜索空间类型可以包括有PDCCH search space为普通搜索空间(common search space)、以及UE专用(UE-specific)空间space。当然，可能还会存在其他的配置参数，只是本示例中不再进行穷举。
本示例中，至少一个监听时刻可以为一个持续时长内的全部监听时刻；或者，可以为一个持续时长内的一部分监听时刻。
结合图3-1，本示例提供一种在持续时长内包含全部的监听时刻，并且M＝2也就是2个持续时长的示意。具体的：其中每一个持续时长是一个完整的持续时长，也就是持续时长内的PDCCH监听时刻均在确定的PDCCH监听时间段内。终端设备从基于PS_offset得到的监听PDCCH的起始位置开始，在2个“持续时长”内的PDCCH监听时刻监听PDCCH。在图3-1中虚线的PDCCH监听时刻中终端不监听PDCCH，另外为了简洁，图3-1示未画出所有PDCCH search space周期的PDCCH监听位置，仅绘出DRX ON之前部分的PDCCH监听位置作为示意，并不代表监听时刻对应的监听位置只能是图中示意的位置。
结合图3-2，同样以M＝2也就是2个持续时长的示意，针对了本示例提供一种在持续时长内包含部分的监听时刻，也就是包含不完整的持续时长，但包含至少一个PDCCH监听时刻，如被前述参数PS_offset截断的Duration也可以视为一个duration被计数。如下图3-2所示，M＝2。终端从基于PS_offset得到的监听PDCCH的起始位置开始监听PDCCH，其中第一个Duration仅PS_offset指示的起始监听时间点之后的PDCCH监听时刻被监听。图中阴影斜线部分的符号对应的监听时刻则是未落入监听时间段之内的部分，因此不在该对应的时刻进行节能信号PDCCH的监听。
一种优选的示例中，前述至少一个监听时刻中，每一个监听时刻需要为有效的监听时刻。
关于有效的监听时刻，其中有效性的规则定义可以参见以下说明：
当终端设备(比如，新无线NR终端)工作于单小区操作或载波聚合的状态下，且终端设备在一个或多个小区中的激活带宽部分(BWP，BandWidth Part)中监听的具有相同的空间准共址(QCL)-TypeD属性的PDCCH CORESETs中的PDCCH监听时刻重叠时，终端设备仅在前述一个或多个小区中的激活BWP中的一个COESET的监听时刻进行节能信号PDCCH的监听；或，所述终端设备在其他任何与该CORESET具有相同 的QCL-TypeD属性的CORESET中监听节能信号PDCCH。其中，所述CORESET满足下列条件：
CORESET包含CSS的小区中最小索引小区的最小索引的CSS集合；
若CORESET不包含CSS的小区中最小索引小区的最小索引的CSS集合，则所述CORESET包含对应有USS的最小索引小区的最小索引的USS集合。
其中，所述最小索引的USS集合的索引是在所有在重叠的PDCCH监听时刻中包含至少一个PDCCH candidate的USS集合中确定的。
进一步地，还包含以下定义：一个SS/PBCH block被认为与一个CSI-RS具有不同的QCL-typeD属性；
第一个小区中与一个SS/PBCH block关联的CSI-RS，与第二小区中同样与该SS/PBCH block关联的第二CSI-RS，被认为是具有相同的QCL-TypeD属性。
相反地，如果一个终端设备被配置工作在单小区操作或载波聚合操作且在多个不具有QCL-TypeD属性但重叠的PDCCH COREST中监听PDCCH，在重叠的PDCCH监听时刻，则终端需要在前述CORESET所对应的PDCCH监听时刻中，监听PDCCH。也就是说，这种情况下，前述CORESET所对应的监听时刻均可以为有效的监听时刻。
结合前述有效性的描述，也就是说，将至少包含一个有效的监听时刻的持续时长Duration可以视为一个duration被计数。
结合有效性的优选示例，可以进一步地认为，如果某一个持续时长中不包含有有效的监听时刻，那么可以就可以认为该持续时长不被计数，从下一个持续时长再进一步判断是否包含有至少一个有效的监听时刻，进而再确定下一个持续时长是否计数，如此循环处理，直至在本次监听时间段内全部持续时长结束为止。
示例2、与示例1不同在于，针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
本示例提供的方案为终端设备基于所述K个节能信号搜索空间(具体为PDCCH search space)中每一个节能信号搜索空间对应的至少一个配置参数，分别确定每一个节能信号搜索空间所对应的监听时间段中的M个持续时长。
与示例1相同在于，前述M可以为配置的、或者可以为预定义的；其中M为配置的情况中，可以为终端设备接收网络设备为其配置的M，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该M值。优选的，M＝1。
与示例1不同在于，如果K大于1那么存在多个节能信号搜索空间，也就是最终监听时间段中包含有K*M个持续时长。
还需要指出的是，前述K*M个持续时长中，不同的节能信号搜索空间的持续时长可能存在重叠，那么可以基于K*M个持续时长来确定一个总的持续时长。比如，两个节能信号搜索空间中，第一节能信号搜索空间包含4个持续时长，对应了时隙1、3、5、7；第二节能信号搜索空间包含4个持续时长，对应了时隙3、5、7、9；那么可以确定一个最长的持续时长，起始时间可以为时隙1的起始时刻，结束时间可以为时隙9的终止时刻。
当然，如果不同节能信号搜索空间的持续时长的监听时刻不存在重叠的情况下，可以认为监听时间段包含有K*M个持续时长；或者，也可以根据K*M个持续时长确定一个总的持续时长，比如，第一节能信号搜索空间包含的持续时长，对应了时隙1、3，第二节能信号搜索空间包含的持续时长包含时隙2、4，那么可以认为监听时间段包含有时隙1、2、3、4；或者，可以认为监听时间段包含的一个持续时长，起始时间为时隙1的起始时刻，终止时间为时隙4的终止时刻。
关于本示例中，每一个节能信号搜索空间中的M个持续时长的确定方式，与示例1 是相同的；另外，每一个节能信号搜索空间中每一个持续时长中包含至少一个监听时刻(或者至少一个有效的监听时刻)等相关说明也与示例1相同，因此本示例不再重复说明。
示例3、同样针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
与示例2不同在于，本示例中，所述监听时间段，包含：M个持续时长；M为大于等于1的整数。也就是，全部K个节能信号搜索空间对应相同的M个持续时长，比如，M＝1的时候，那么全部K个节能信号搜索空间采用同样的一个持续时长。
其中，所述M个持续时长中的每一个持续时长的长度，可以为以下之一：
K个节能信号搜索空间的至少一个持续时长中最长的持续时长的长度；
预设时间长度；
K个节能信号搜索空间的至少一个持续时长中最长的持续时长的预设倍数；
预设时间长度的预设倍数。
具体来说，K个节能信号搜索空间的至少一个持续时长中最长的持续时长的长度，可以包括：
先基于每一个节能信号搜索空间的至少一个配置参数，确定每一个节能信号搜索空间的持续时长的长度；然后从K个节能信号搜索空间所对应的多种持续时长中，选取最长的一个持续时长的长度，作为本示例中最终采用的持续时长的长度。
其中，基于每一个节能信号搜索空间的至少一个配置参数，确定持续时长的长度的方式，与前述示例1相同，这里不再赘述。相应的，确定了持续时长之后，确定至少一个监听时刻的方式也与前述示例1相同，同样不再赘述。
K个节能信号搜索空间的至少一个持续时长中最长的持续时长的预设倍数中，预设倍数可以为预定义的，或者可以为网络设备通过RRC信令通知给终端设备的；比如，N＝2，那么最终确定的M个持续时长的每一个持续时长的长度为，前述确定的最长的持续时长的2倍。
另外，前述预设时间长度，也可以为预先定义好的(比如，可以为协议规定，或者是默认值)，又或者可以为网络设备通过RRC携带并通知给终端设备的。关于预设时间长度的预设倍数，其中预设倍数可以为预定义的，或者可以为网络设备通过RRC信令通知给终端设备的。
关于本示例中每一个持续时长中包含至少一个监听时刻(或者至少一个有效的监听时刻)等相关说明也与示例1相同，因此本示例不再重复说明。
示例4、K＝1，也就是终端设备被配置一个节能信号搜索空间的情况。
与前述示例1-3均不同，本示例中，所述监听时间段，包括：K个节能信号搜索空间中每一个节能信号搜索空间的N个监听时刻；N为大于等于1的整数。
由于本示例针对K＝1的场景，因此，本示例的监听时间段中包含有针对配置的一个节能信号搜索空间的N个监听时刻。
前述N可以为配置的、或者可以为预定义的；其中N为配置的情况中，可以为终端设备接收网络设备为其配置的N，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该N值。
所述终端设备可以基于节能信号搜索空间的至少一个配置参数，来确定对应的N个监听时刻。其中，所述节能信号搜索空间，也就是PDCCH search space中所述至少一个配置参数，可以包括以下至少之一：
用于指示在对应的节能信号搜索空间的周期内连续监听的时隙个数的第一参数；
用于指示在对应的节能信号搜索空间中节能信号PDCCH监听时刻的起始符号的第二参数。
这里，所述第一参数可以为PDCCH Search Space中的“Duration”参数，第二参数可以为PDCCH Search Space中的“monitoringSymbolsWithinSlot”参数。
具体的，可以基于第一参数来确定一个持续时长的长度；第二参数可以用于确定从哪个起始符号开始进行监听。
进一步地，所述第二参数可以包含有bitmap(比特图)，该比特图可以指示每一个监听时刻的起始符号，换句话说，监听时刻有多少个可以通过bitmap来确定的；比如，bitmap指示“1001001”，那么可以认为从第一个符号起为一个监听时刻，第四个符号也为一监听时刻的起始符号，第7个符号也为一监听时刻的起始符号。再进一步地，可以通过CORESET来确定每一个起始符号对应多少个监听时刻，比如，第一个起始符号起两个监听时刻，第4个符号起两个监听时刻等等。
结合图3-3，以N＝4为例进行说明，所述监听时间段中包含N个监听时刻。终端设备从基于PS_offset得到的监听PDCCH的监听起始时刻开始监听PDCCH，直至完成在N＝4个PDCCH监听时刻监听PDCCH。
一种优选的示例中，前述至少一个监听时刻中，每一个监听时刻需要为有效的监听时刻。这里，关于有效的监听时刻中有效性的定义与示例1相同，不再赘述。
结合图3-4，图3-4中灰色符号对应的监听时刻为无效或落在监听时间段之外的监听时刻。同样以N＝4为例，在PS_offset得到的监听PDCCH的起始位置之后，第一个PDCCH监听位置为有效的PDCCH监听位置，但第二个PDCCH监听位置为无效的监听时刻，因此终端需要监听至PS_offset得到的监听PDCCH的起始位置之后的第5个监听时刻以得到N＝4个有效的监听时刻。
示例5、与示例4不同在于，针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
本示例提供的方案为终端设备基于所述K个节能信号搜索空间(具体为PDCCH search space)中每一个节能信号搜索空间对应的至少一个配置参数，分别确定每一个节能信号搜索空间所对应的监听时间段中的N个监听时刻。
与示例4相同在于，前述N可以为配置的、或者可以为预定义的。
与示例1不同在于，如果K大于1，存在多个节能信号搜索空间，也就是最终监听时间段中包含有K*N个监听时刻。
关于本示例中，每一个节能信号搜索空间中的N个监听时刻的确定方式，与示例4是相同的；另外，N个监听时刻为有效的监听时刻等相关说明也与示例4相同，因此本示例不再重复说明。
示例6、同样针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
与示例5不同在于，本示例中，所述监听时间段，包含：N个监听时刻。也就是无论存在多少个节能信号搜索空间，均采用相同的N个监听时刻进行监听。这里N个监听时刻的确定方法，可以为随机采用任意一个节能信号搜索空间中监听时间段内的N个监听时刻(或者，N个有效的监听时刻)；又或者，可以为选取两个或更多的节能信号搜索空间中每一个监听时间段内的一些(一个或多个)最终组成N个监听时刻。当然，还可能存在其他的方式，这里不再穷举。
示例7、
与前述示例均不同，本示例中，所述监听时间段中，包括：K节能信号搜索空间中 每一个节能信号搜索空间的L个监听时隙；L为大于等于1的整数。
本示例的监听时间段中包含有针对配置的一个节能信号搜索空间的L个监听时隙。又或者，针对K大于1的情况中，同样对每一个节能信号搜索空间确定L个监听时隙，最终监听时间段中包含有K*L个监听时隙。
前述L可以为配置的、或者可以为预定义的；其中L为配置的情况中，可以为终端设备接收网络设备为其配置的L，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该L值。
所述终端设备可以基于节能信号搜索空间的至少一个配置参数，来确定对应的L个监听时隙。其中，所述节能信号搜索空间，也就是PDCCH search space中所述至少一个配置参数，可以包括以下至少之一：
用于指示在对应的节能信号搜索空间的周期内连续监听的时隙个数的第一参数；
用于指示在对应的节能信号搜索空间中节能信号PDCCH监听时刻的起始符号的第二参数。
这里，所述第一参数可以为PDCCH Search Space中的“Duration”参数，第二参数可以为PDCCH Search Space中的“monitoringSymbolsWithinSlot”参数。
可以基于第一参数来确定一个持续时长的包含的时隙个数。第二参数可以用于确定从哪个起始符号开始进行监听。
进一步地，所述第二参数可以包含有bitmap(比特图)，该比特图可以指示每一个监听时刻的起始符号，换句话说，监听时刻有多少个可以通过bitmap来确定的；比如，bitmap指示“1001001”，那么可以认为从第一个符号起，第四个符号也为一起始符号，第7个符号也为一起始符号。如此，可以基于确定的每一个起始符号进一步确定多个监听时隙。
结合图3-3，以L＝2为例进行说明，所述监听时间段中包含L个监听时隙。终端设备从基于PS_offset得到的监听PDCCH的监听起始时刻开始监听PDCCH，直至完成在N＝2个监听时隙内监听节能信号PDCCH。
一种优选的示例中，前述L个监听时隙中包含的监听时刻需要为有效的监听时刻。这里，关于有效的监听时刻中有效性的定义与示例1相同，不再赘述。进一步地，如果某一个监听时隙中包含的监听时刻为无效的，那么可以不对该监听时隙进行计数。
结合图3-5，图3-5中灰色符号对应的监听时刻为无效或落在监听时间段之外的监听时刻。同样以L＝2为例，在PS_offset得到的监听PDCCH的起始位置之后，第一个监听时隙中，存在一个无效的监听时刻，那么从第二个监听时隙开始计数，因此终端设备需要监听到第三个监听时隙得到L＝2个监听时隙。
示例8、与示例7不同在于，所述监听时间段，包含：L个监听时隙。也就是无论存在多少个节能信号搜索空间，均采用相同的L个监听时隙进行监听。这里L个监听时隙的确定方法，可以为随机采用任意一个节能信号搜索空间中监听时间段内的L个监听时隙(或者，N个有效的监听时刻)；又或者，可以为选取两个或更多的节能信号搜索空间中每一个监听时间段内的一些(一个或多个)最终组成L个监听时隙。当然，还可能存在其他的方式，这里不再穷举。
示例9、
在前述各个示例的基础上，本示例增加引入第三参数，所述终端设备基于第三参数，调整所述监听时间段，得到调整后的监听时间段。
具体的，所述终端设备基于第三参数，调整所述监听时间段，还包括：
将所述监听时间段中，与DRX ON时间段的起始时刻之间的时间间距小于第三参数的监听时刻去除后，得到调整后的监听时间段。
也就是基于前述示例1-8任一示例得到监听时间段之后，可以再基于第三参数从监听时间段中取出一部分监听时刻，得到调整后的监听时间段。
具体的：
当监听时间段中包含M个持续时长，每一个持续时长包含至少一个监听时刻，或者每一个持续时长包含至少一个有效的监听时刻的时候；基于第三参数进行监听时间段的调整之后，可能某一个持续时长中的一个或多个监听时刻(或者有效的监听时刻)会被去掉。如图3-6所示，原先确定的监听时间段中，包含有第一个和第二个持续时长中的监听时刻；通过第三参数调整之后，将第二个持续时长中灰色部分的监听时刻去掉，仅剩余第二个持续时长中的第一个监听时刻，调整后的监听时间段如图中所示，包含有第一个持续时长的部分监听时刻，以及第二个持续时长中的去掉灰色部分的监听时刻之后的剩余监听时刻。
当监听时间段中包含N个监听时刻；基于第三参数进行监听时间段的调整之后，可能一个或多个监听时刻(或者有效的监听时刻)会被去掉。
当监听时间段中包含L个监听时隙；基于第三参数进行监听时间段的调整之后，可能某一个监听时隙中的一个或多个监听时刻(或者有效的监听时刻)会被去掉。
所述第三参数，用于指示终端设备由接收到所述节能信号PDCCH起始、至所述终端设备能够在DRX ON时间段的起始时刻(也就是在DRX ON时间段的期间内开始正常进行数据传输的时刻)为止所需要的最短时间。可以将第三参数记为PS_offsetMin，另外，第三参数可以为预设的，或者，可以为网络设备为终端设备配置的，或者协议规定的，这里不做穷举。
前述第三参数无论是网络侧配置给终端设备的，或者是协议规定的，网络设备也同样可以根据所述第三参数对监听时间段进行调整，得到调整后的监听时间段。进而网络设备可以确定终端设备的监听时间段，从而在对应的监听位置处为终端设备发送节能信号PDCCH。
可见，通过采用上述方案，就能够根据节能信号搜索空间的至少一个配置参数确定对应的监听时间段，进而在监听时间段中对节能信号PDCCH进行监听。如此，提供了如何采用配置参数确定节能信号的监听时间段的方案，弥补了相关技术中的空缺，并且，上述方案的执行不需要在现有参数的基础上增加其他需要配置的参数，因此，也保证了不会增加终端设备与网络设备之间的信令开销。
本发明实施例提供了一种信终端设备，如图4-1所示，包括：
第一通信单元41，在非连续接收DRX ON时间段之前、且在监听起始时刻之后，在监听时间段中监听节能信号PDCCH；
其中，所述监听时间段由K个节能信号搜索空间中每一个节能信号搜索空间的至少一个配置参数确定；K为大于等于1的整数。
所述终端设备，还包括：第一处理单元42，基于配置的节能(PS，Power Saving)-偏置Offset、以及所述DRX ON时间段的起始时刻，确定所述监听起始时刻。
所述网络设备，如图4-2所示，包括：
第二通信单元51，在非连续接收DRX ON时间段之前、且在监听起始时刻之后，在监听时间段中发送节能信号PDCCH；
其中，所述监听时间段由K个节能信号搜索空间中每一个节能信号搜索空间的至少一个配置参数确定；K为大于等于1的整数。
所述网络设备，还包括：第二处理单元52，基于配置的节能(PS，Power Saving)-偏置Offset、以及所述DRX ON时间段的起始时刻，确定所述监听起始时刻。
本实施例可以应用于终端设备被配置一个节能信号搜索空间的场景中，也可以应用 于终端设备被配置多个节能信号搜索空间的场景中，下面结合多种示例对本实施例提供的方案进行说明：
示例1、K＝1，也就是终端设备被配置一个节能信号搜索空间的情况。
本示例中，所述监听时间段，包含：K个节能信号搜索空间中每一个节能信号搜索空间的M个持续时长；M为大于等于1的整数。
由于本示例针对K＝1的场景，因此，本示例的监听时间段中包含有针对配置的节能信号搜索空间的M个持续时长。
前述M可以为配置的、或者可以为预定义的；其中M为配置的情况中，可以为终端设备接收网络设备为其配置的M，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该M值。优选的，M＝1。
所述M个持续时长中的每一个持续时长中，包含：至少一个监听时刻。
所述终端设备可以基于节能信号搜索空间的至少一个配置参数，来确定对应的监听时间段。其中，所述节能信号搜索空间，也就是PDCCH search space中所述至少一个配置参数，可以包括以下至少之一：
用于指示在对应的节能信号搜索空间的周期内连续监听的时隙个数的第一参数；
用于指示在对应的节能信号搜索空间中节能信号PDCCH监听时刻的起始符号的第二参数。
这里，所述第一参数可以为PDCCH Search Space中的“Duration”参数，第二参数可以为PDCCH Search Space中的“monitoringSymbolsWithinSlot”参数。
本示例中，至少一个监听时刻可以为一个持续时长内的全部监听时刻；或者，可以为一个持续时长内的一部分监听时刻。
一种优选的示例中，前述至少一个监听时刻中，每一个监听时刻需要为有效的监听时刻。
示例2、与示例1不同在于，针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
本示例提供的方案为终端设备基于所述K个节能信号搜索空间(具体为PDCCH search space)中每一个节能信号搜索空间对应的至少一个配置参数，分别确定每一个节能信号搜索空间所对应的监听时间段中的M个持续时长。
与示例1相同在于，前述M可以为配置的、或者可以为预定义的；其中M为配置的情况中，可以为终端设备接收网络设备为其配置的M，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该M值。优选的，M＝1。
与示例1不同在于，如果K大于1那么存在多个节能信号搜索空间，也就是最终监听时间段中包含有K*M个持续时长。
示例3、同样针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
与示例2不同在于，本示例中，所述监听时间段，包含：M个持续时长；M为大于等于1的整数。也就是，全部K个节能信号搜索空间对应相同的M个持续时长，比如，M＝1的时候，那么全部K个节能信号搜索空间采用同样的一个持续时长。
其中，所述M个持续时长中的每一个持续时长的长度，可以为以下之一：
K个节能信号搜索空间的至少一个持续时长中最长的持续时长的长度；
预设时间长度；
K个节能信号搜索空间的至少一个持续时长中最长的持续时长的预设倍数；
预设时间长度的预设倍数。
示例4、K＝1，也就是被配置一个节能信号搜索空间的情况。
与前述示例1-3均不同，本示例中，所述监听时间段，包括：K个节能信号搜索空间中每一个节能信号搜索空间的N个监听时刻；N为大于等于1的整数。
由于本示例针对K＝1的场景，因此，本示例的监听时间段中包含有针对配置的一个节能信号搜索空间的N个监听时刻。
示例5、与示例4不同在于，针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
本示例提供的方案为终端设备基于所述K个节能信号搜索空间(具体为PDCCH search space)中每一个节能信号搜索空间对应的至少一个配置参数，分别确定每一个节能信号搜索空间所对应的监听时间段中的N个监听时刻。
示例6、同样针对K>1的情况进行说明，即针对当终端被配置多个节能信号搜索空间监听基于PDCCH的节能信号(也就是节能信号PDCCH)时的方案。
与示例5不同在于，本示例中，所述监听时间段，包含：N个监听时刻。也就是无论存在多少个节能信号搜索空间，均采用相同的N个监听时刻进行监听。这里N个监听时刻的确定方法，可以为随机采用任意一个节能信号搜索空间中监听时间段内的N个监听时刻(或者，N个有效的监听时刻)；又或者，可以为选取两个或更多的节能信号搜索空间中每一个监听时间段内的一些(一个或多个)最终组成N个监听时刻。当然，还可能存在其他的方式，这里不再穷举。
示例7、
与前述示例均不同，本示例中，所述监听时间段中，包括：K节能信号搜索空间中每一个节能信号搜索空间的L个监听时隙；L为大于等于1的整数。
本示例的监听时间段中包含有针对配置的一个节能信号搜索空间的L个监听时隙。又或者，针对K大于1的情况中，同样对每一个节能信号搜索空间确定L个监听时隙，最终监听时间段中包含有K*L个监听时隙。
前述L可以为配置的、或者可以为预定义的；其中L为配置的情况中，可以为终端设备接收网络设备为其配置的L，具体可以通过无线资源控制(RRC，Radio Resource Control)信令携带该L值。
一种优选的示例中，前述L个监听时隙中包含的监听时刻需要为有效的监听时刻。这里，关于有效的监听时刻中有效性的定义与示例1相同，不再赘述。进一步地，如果某一个监听时隙中包含的监听时刻为无效的，那么可以不对该监听时隙进行计数。
示例8、与示例7不同在于，所述监听时间段，包含：L个监听时隙。也就是无论存在多少个节能信号搜索空间，均采用相同的L个监听时隙进行监听。
示例9、
在前述各个示例的基础上，本示例增加引入第三参数，所述终端设备基于第三参数，调整所述监听时间段，得到调整后的监听时间段。
具体的，所述终端设备基于第三参数，调整所述监听时间段，还包括：
将所述监听时间段中，与DRX ON时间段的起始时刻之间的时间间距小于第三参数的监听时刻去除后，得到调整后的监听时间段。
也就是基于前述示例1-8任一示例得到监听时间段之后，可以再基于第三参数从监听时间段中取出一部分监听时刻，得到调整后的监听时间段。
所述第三参数，用于指示终端设备由接收到所述节能信号PDCCH起始、至所述终端设备能够在DRX ON时间段的起始时刻为止所需要的最短时间。可以将第三参数记为PS_offsetMin，另外，第三参数可以为预设的，或者，可以为网络设备为终端设备配置的，或者协议规定的，这里不做穷举。
前述第三参数无论是网络侧配置给终端设备的，或者是协议规定的，网络设备的第 二处理单元52，也同样可以根据所述第三参数对监听时间段进行调整，得到调整后的监听时间段。进而网络设备可以确定终端设备的监听时间段，从而通过第二通信单元51在对应的监听位置处为终端设备发送节能信号PDCCH。
可见，通过采用上述方案，就能够根据节能信号搜索空间的至少一个配置参数确定对应的监听时间段，进而在监听时间段中对节能信号PDCCH进行监听。如此，提供了如何采用配置参数确定节能信号的监听时间段的方案，弥补了相关技术中的空缺，并且，上述方案的执行不需要在现有参数的基础上增加其他需要配置的参数，因此，也保证了不会增加终端设备与网络设备之间的信令开销。
