相关申请的交叉引用
本申请要求在2019年01月11日提交国家知识产权局、申请号为201910028855.8、申请名称为“一种信道检测方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种信道检测方法及设备。
背景技术
目前，基站会向终端设备传输物理下行共享信道(physical downlink shared channel，PDSCH)，而PDSCH一般是通过物理下行控制信道(physical downlink control channel，PDCCH)中承载的控制信息来调度，控制信息例如为下行控制信息(downlink control information，DCI)。因此，为了正确接收PDSCH，终端设备需要先检测PDCCH，根据PDCCH承载的DCI获得用于接收PDSCH所需要的相关信息，例如PDSCH时频资源位置和大小，或多天线配置信息等。
一般而言，基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长的时间内可能没有数据传输。如果终端设备持续检测PDCCH，可能在很长时间内是做无用功，而且对于终端设备来说功耗较大。
发明内容
本申请实施例提供一种信道检测方法及设备，用于减小终端设备的功耗。
第一方面，提供第一种信道检测方法，该方法包括：终端设备在一个检测周期内的n个传输机会上检测第一信号，n为正整数；当所述终端设备在所述n个传输机会中的至少一个传输机会上检测到第一信号时，所述终端设备在所述检测周期中的第一时间段内检测下行控制信道和/或第二信号；或者，当所述终端设备在所述n个传输机会上均未检测到第一信号，所述终端设备在所述检测周期内不检测下行控制信道。
该方法可由第一通信装置执行，第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。这里以第一通信装置是终端设备为例。
在本申请实施例中，如果网络设备有数据调度，则可以发送第一信号，如果网络设备在n个传输机会之后的一段时间内不调度数据，则网络设备可以不发送第一信号，那么终端设备在n个传输机会上就检测不到第一信号，此时终端设备在第二时间段内就可以不检测下行控制信道，从而减少终端设备做无用功的几率，也节省终端设备的功耗。
结合第一方面，在第一方面的一种可能的实施方式中，所述第一时间段通过第一定时器进行计时，所述第一定时器的定时时长为所述第一时间段的长度。
终端设备可以通过第一定时器来对第一时间段进行计时，从而可以明确第一时间段的 起止位置。
结合第一方面，在第一方面的一种可能的实施方式中，在所述终端设备在所述检测周期中的第一时间段内检测下行控制信道和第二信号的情况下，所述方法还包括：当所述终端设备在所述第一定时器的定时时长内检测到第二信号时，所述终端设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内检测所述下行控制信道；或者，当所述终端设备在所述第一定时器的定时时长内检测到所述第二信号且所述第二信号指示继续检测下行控制信道时，所述终端设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内检测所述下行控制信道。
如果终端设备在第一定时器的定时时长内检测到了第二信号，表明后续网络设备可能会发送下行控制信道，因此终端设备可以检测下行控制信道，而且终端设备还可以根据第二信号重置第一定时器，例如网络设备可能有较多的数据发送，通过重置第一定时器，使得终端设备能够在较为充足的时间内接收下行控制信道，尽量保证终端设备能够完整接收数据。第二信号可以有不同的实现方式，其中，第二信号可以通过信号本身来作为节能信号，在这种情况下，终端设备根据是否接收第二信号就可以确定应如何处理，对于第二信号承载的内容并不作限制，实现较为简单。或者，第二信号也可以通过第二信号所承载的内容来进行不同的指示，终端设备在接收第二信号后需要确定第二信号具体指示的内容，从而确定下一步的操作，这种方式可以使得第二信号的指示更为明确。
结合第一方面，在第一方面的一种可能的实施方式中，在所述终端设备在所述检测周期中的第一时间段内检测下行控制信道和第二信号的情况下，所述方法还包括：在所述第一定时器的定时时长内，当所述终端设备尚未检测到所述第二信号时，对所述下行控制信道进行检测。
因为网络设备可能既发送下行控制信道也发送第二信号，因此即使终端设备未检测到第二信号，也可以检测下行控制信道，从而尽量保证对于下行控制信道的及时接收。
结合第一方面，在第一方面的一种可能的实施方式中，在所述终端设备在所述检测周期中的第一时间段内检测第二信号的情况下，所述方法还包括：当所述终端设备在所述第一定时器的定时时长内检测到第二信号时，所述终端设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内检测所述下行控制信道；或当所述终端设备在所述第一定时器的定时时长内检测到所述第二信号且所述第二信号指示检测下行控制信道时，所述终端设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内检测所述下行控制信道。
如果终端设备在第一定时器的定时时长内检测到了第二信号，表明后续网络设备可能会发送下行控制信道，因此终端设备可以检测下行控制信道，而且终端设备还可以根据第二信号重置第一定时器，例如网络设备可能有较多的数据发送，通过重置第一定时器，使得终端设备能够在较为充足的时间内接收下行控制信道，尽量保证终端设备能够完整接收数据。第二信号可以有不同的实现方式，其中，第二信号可以通过信号本身来作为节能信号，在这种情况下，终端设备根据是否接收第二信号就可以确定应如何处理，对于第二信号承载的内容并不作限制，实现较为简单。或者，第二信号也可以通过第二信号所承载的内容来进行不同的指示，终端设备在接收第二信号后需要确定第二信号具体指示的内容，从而确定下一步的操作，这种方式可以使得第二信号的指示更为明确。
结合第一方面，在第一方面的一种可能的实施方式中，在所述终端设备在所述检测周 期中的第一时间段内检测第二信号的情况下，所述方法还包括：在所述第一定时器的定时时长内，当所述终端设备尚未检测到所述第二信号时，不对下行控制信道进行检测。
在这种情况下，网络设备会在发送第二信号后再发送下行控制信道，因此如果终端设备未检测到第二信号，则无需检测下行控制信道，这样可以减小终端设备的功耗。
结合第一方面，在第一方面的一种可能的实施方式中，所述方法还包括：当所述终端设备在所述第一定时器的定时时长内检测到所述第二信号且所述第二信号指示暂停检测下行控制信道时，所述终端设备在第三时间段内暂停检测所述下行控制信道。
如果第二信号指示暂停检测下行控制信道，表明网络设备在未来的一段时间内可能不会发送下行控制信道，那么终端设备在第三时间段内例如进入“睡眠”状态，在第三时间段内，终端设备可以暂停检测下行控制信道，也可以暂停检测第二信号，以减小功耗。
结合第一方面，在第一方面的一种可能的实施方式中，所述方法还包括：当所述终端设备在所述第一定时器的定时时长内检测到所述第二信号且所述第二信号指示暂停检测下行控制信道时，保持所述第一定时器继续运行。
如果第二信号指示暂停检测下行控制信道，终端设备虽然暂停检测下行控制信道，但是依然可以保持第一定时器继续运行，以实现继续计时。
结合第一方面，在第一方面的一种可能的实施方式中，所述方法还包括：当所述第一定时器超时时，所述终端设备停止检测所述下行控制信道和所述第二信号。
在第一定时器超时时，网络设备不再发送下行控制信道和第二信号，例如数据发送过程可能已完毕，那么终端设备也可以停止检测所述下行控制信道和所述第二信号，以减小功耗。
结合第一方面，在第一方面的一种可能的实施方式中，当所述第一定时器运行时，所述终端设备不检测所述第一信号。
在第一定时器运行时，网络设备有可能还会发送第一信号，例如第一信号是UE组特定信号，那么为了照顾到一组终端设备的需求，网络设备可能会持续发送第一信号。那么对于第一定时器已开始运行的终端设备来说，可以不再检测第一信号，以正常完成其他检测过程。
结合第一方面，在第一方面的一种可能的实施方式中，所述终端设备在所述第一定时器的定时时长内周期性检测所述第二信号。
网络设备可以周期性发送第二信号，则终端设备对于第二信号的检测也可以是周期性的。例如，终端设备对于第二信号的检测周期可以小于或等于终端设备对于第一信号的检测周期，当然也可能终端设备对于第二信号的检测周期大于终端设备对于第一信号的检测周期，具体的不做限制。
结合第一方面，在第一方面的一种可能的实施方式中，所述第一信号用于指示所述第一时间段的时长。
例如第一时间段的时长可以他通过第一信号来指示，则终端设备接收第一信号后就可以确定第一时间段的时长。或者终端设备也可以通过其他方式确定第一时间段的时长，例如还可以通过协议规定等方式，具体的不做限制。
结合第一方面，在第一方面的一种可能的实施方式中，所述n个传输机会为n个连续的传输机会。
例如，n个传输机会可以是连续的，这样可以方便终端设备的检测。或者n个传输机 会也可以两两之间均不连续，或者n个传输机会也可以有部分传输机会连续，而这部分传输机会和剩余的传输机会不连续，具体的不做限制。
结合第一方面，在第一方面的一种可能的实施方式中，所述第一信号是基于第一序列生成的，所述第二信号是基于第二序列生成的，所述第一序列属于第一序列集合，所述第二序列属于第二序列集合，所述第一序列集合为所述第二序列集合的子集；或，所述第一信号承载第一状态值，所述第二信号承载第二状态值，所述第一状态值属于第一状态值集合，所述第二信息状态值属于第二状态值集合，所述第一状态值集合为第二状态值集合的子集。
在本申请实施例中，第一信号和第二信号可以是基于序列生成的，或者也可以不是基于序列生成的，例如是信令的形式，也就是对信息域的比特进行信道编码后传输。当然除此之外也还可以有其它的生成方式，较为灵活。
结合第一方面，在第一方面的一种可能的实施方式中，所述检测周期为DRX周期，所述第一时间段的起始位置为一个DRX周期的起始位置，所述终端设备在所述第一时间段内只开启第一定时器。
作为一种实施方式，第一信号可以与DRX机制相结合。那么在本申请实施例中，第一时间段的时间起始位置可以是一个DRX周期的时间起始位置，终端设备检测第一信号的周期可以直接为DRX周期，在这种情况下，该DRX周期的on duration timer的计时时长是0ms，在该DRX周期的激活时间内，终端设备在该DRX周期的起始位置上只开启第一定时器，此时认为非激活定时器就没有了。或者，在这种情况下，在该DRX周期的激活时间内，终端设备在该DRX周期的起始位置上只开启第一定时器，此时认为on duration timer和非激活定时器都没有了。或者，第一定时器也可以是inactivity timer，inactivity timer在DRX周期的起始位置处启动，或者，只要终端设备检测到第一信号就启动inactivity timer，在这种情况下，on duration timer就没有了。其中，第一定时器的运行时间可以是该DRX周期的激活时间。本申请实施例通过一个定时器(第一定时器)代替了DRX周期中原有的两个定时器，相对于现在的方案来说，本申请实施例的方案更为简单。
第二方面，提供第二种信道检测方法，该方法包括：网络设备确定在一个检测周期内对于终端设备进行数据调度；所述网络设备在所述检测周期内的n个传输机会上发送第一信号，所述第一信号用于指示数据调度，n为正整数。
该方法可由第二通信装置执行，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。这里以第二通信装置是网络设备为例。
结合第二方面，在第二方面的一种可能的实施方式中，所述方法还包括：所述网络设备在所述检测周期中的第一时间段内发送下行控制信道和/或第二信号。
结合第二方面，在第二方面的一种可能的实施方式中，所述第一时间段通过第一定时器进行计时，所述第一定时器的定时时长为所述第一时间段的长度。
结合第二方面，在第二方面的一种可能的实施方式中，在所述网络设备在所述检测周期中的第一时间段内发送下行控制信道和第二信号的情况下，所述方法还包括：当所述网络设备在所述第一定时器的定时时长内发送第二信号时，所述网络设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内发送所述下行控制信道；或者，当所述网络设备在所述第一定时器的定时时长内发送所述第二信号且所述第二信号指示继续检测 下行控制信道时，所述网络设备重置所述第一定时器，并在重置后的所述第一定时器的定时时长内发送所述下行控制信道。
结合第二方面，在第二方面的一种可能的实施方式中，在所述网络设备在所述检测周期中的第一时间段内发送下行控制信道和第二信号的情况下，所述方法还包括：在所述第一定时器的定时时长内，当所述网络设备尚未发送所述第二信号时，发送所述下行控制信道。

而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(the 5 th generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。

如上介绍了本申请实施例涉及的一些概念，下面介绍本申请实施例的技术特征。
在NR系统中，频域上的基本单位为一个子载波，子载波间隔(subcarrier spacing，SCS)可以为15KHz或30KHz等。在NR系统的物理层中，上/下行频域资源的单位是物理资源 块(physical resource block，PRB)，每个PRB由频域上12个连续的子载波组成。请参考图1，为下行时频资源网格。图1中的
Figure PCTCN2020070323-appb-000001
表示一次下行调度的资源块(resource block，RB)的个数，一个RB在频域上包括12个连续的子载波，资源网格上的每个元素称为一个资源元素(resource element，RE)，RE为最小的物理资源，包含一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号内的一个子载波。上行时频资源的网格与下行是类似的。在NR系统中，下行资源调度的基本时间单位是一个时隙(slot)，一般而言，一个slot在时间上由14个OFDM符号组成。
目前，基站会向终端设备传输PDSCH，而PDSCH一般是通过PDCCH中承载的控制信息来调度，控制信息例如为DCI。因此，为了正确接收PDSCH，终端设备需要先检测PDCCH，根据PDCCH承载的DCI获得用于接收PDSCH所需要的相关信息，例如PDSCH时频资源位置和大小，或多天线配置信息等。PDCCH是在控制资源集合(control-resource set,CORESET)中传输，CORESET在频域上包括多个PRB，在时域上包括1到3个OFDM符号，且这些OFDM符号可位于slot内的任意位置。
控制信道单元(control-channel element，CCE)是构成PDCCH的基本单位，在CORESET中的每个CCE都会有一个对应的索引号。一个给定的PDCCH可由1、2、4、8或16个CCE构成，对于构成一个PDCCH的CCE的数量，可以由DCI载荷大小(DCI payload size)和所需的编码速率决定。其中，构成PDCCH的CCE的数量也被称为聚合等级(aggregation level,AL)。基站可根据实际传输的无线信道的状态，对PDCCH的聚合等级进行调整，实现链路自适应传输。CCE是逻辑概念，因此，一个CCE与物理资源上的6个REG(resource-element group，资源单元组)相对应，一个REG在时域占用一个OFDM符号，在频域占用一个RB，对此可参考图2。
搜索空间(search space)是某个聚合等级下的候选PDCCH(PDCCH candidate)的集合。由于基站实际发送的PDCCH的聚合等级随时间是可变的，而且由于没有相关信令告知终端设备，因此终端设备需要在不同聚合等级下盲检PDCCH。其中，待盲检的PDCCH称为候选PDCCH，某个聚合等级下可以有多个候选PDCCH。可参考图3，为搜索空间的示意。终端设备会在搜索空间内对由CCE构成的所有候选PDCCH进行译码，如果循环冗余校验(cyclic redundancy check，CRC)校验通过，则认为所译码的PDCCH的内容对该终端设备是有效的，终端设备可以继续处理译码后的相关信息。
在NR系统中，为了更好地控制盲检测下行控制信道的复杂度，基站可为终端设备配置一个或多个搜索空间集合(search space set)，其中，每个搜索空间集合包括一个或多个聚合等级对应的搜索空间。即，一个搜索空间集合可以对应于一个或多个聚合等级，一个搜索空间集合可以包括一个或多个聚合等级下的候选PDCCH。
基站为终端设备配置搜索空间集合时，会为每个搜索空间集合配置一个索引号，搜索空间集合会包括候选PDCCH，候选PDCCH都位于相应的CORESET中，因此搜索空间集合的索引号会与搜索空间集合所包括的候选的PDCCH所在的CORESET的索引号相关联，而搜索空间集合所关联的CORESET决定了该搜索空间集合的候选PDCCH在CORESET内的CCE索引。例如，CORESET中一共有24个CCE，搜索空间集合中对应于聚合等级AL＝2的候选PDCCH的数量为6，那么每个候选PDCCH在CORESET内的CCE索引号可以参考图4，图4中画斜线的方框表示候选PDCCH。
在时域上，终端设备以一定的时间间隔检测搜索空间集合中的候选PDCCH，因此对 于每个搜索空间集合会配置一些时域配置信息，包括：
检测周期：检测搜索空间集合的时间间隔，单位为时隙；
时隙偏移：检测周期开始到实际检测搜索空间集合之间的时隙偏移量，且该时隙偏移量小于检测周期的取值；
时隙数量：连续检测搜索空间集合的时隙数量，且时隙数量小于检测周期的取值；
符号位置：每个时隙内，搜索空间集合关联的CORESET的起始符号的位置。
为了方便理解，以具体例子介绍各参数的含义。如图5所示，其中，检测周期为10个时隙，时隙偏移为3个时隙，时隙数量为2个时隙，搜索空间集合相关联的CORESET为一个占用2个OFDM符号的CORESET，符号位置为时隙内OFDM符号0和OFDM符号7。在这个示例中，终端设备在每个10个时隙的检测周期内的时隙3和时隙4内的符号0和符号7上检测CORESET内搜索空间集合的候选PDCCH，且CORESET在时域上占用2个OFDM符号。
在NR系统中，终端设备可以处于不同的状态，其中的一种状态为无线资源控制(radio resource control，RRC)_连接(CONNECTED)状态。在RRC_CONNECTED状态下，终端设备已经建立了RRC上下文(context)，即，终端设备与无线接入网之间通信所必需的参数对于两者是已知的。RRC_CONNECTED状态主要用于无线接入网与终端设备进行数据传输。
一般而言，基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长时间内没有数据传输。如果终端设备持续检测PDCCH，可能在很长时间内是做无用功，而且对于终端设备来说功耗较大。
目前，NR系统中可以为终端设备配置非连续接收(discontinuous reception，DRX)处理机制，在没有数据传输的时候，可以通过使终端设备停止检测PDCCH并停止相应数据传输的方式来降低功耗，从而提升电池的使用时间。
在DRX中，基站可为处于RRC_CONNECTED状态的终端设备配置DRX周期(DRX cycle)，DRX cycle中包含一个“持续时间(on duration)”的时间区域，如图6所示。
在“on duration”的时间内，终端设备可以检测PDCCH。终端设备在每一个DRX cycle的时间起始位置(也就是“On duration”的时间起始位置)开启一个定时器，该定时器的时间长度即为“on duration”的时间长度，该定时器可以称之为DRX-持续时间定时器(drx-ondurationtimer)，简称持续时间定时器，该持续时间定时器的计时时长的范围一般为1～1200ms，终端设备在该持续时间定时器的计时时长内检测PDCCH。如果在该持续时间定时器的计时时长内终端设备没有检测到PDCCH，那么在该持续时间定时器超时时，终端设备进入睡眠状态，即终端设备在DRX cycle的其余时间段内可以关闭接收电路，从而降低终端设备的功耗。如果在持续时间定时器的计时时长内终端设备检测到了PDCCH，那么终端设备就会开启DRX机制中的非激活定时器(drx-inactivitytimer)。如果在非激活定时器的运行时间内，终端设备继续检测到了PDCCH，那么终端设备会重置(restart)该非激活定时器，使得该非激活定时器重新开始计数，同理，在该非激活定时器重新开始计数后，如果终端设备又检测到了PDCCH，则终端设备会再次重置该非激活定时器，使得该非激活定时器重新开始计数，以此类推。如果非激活定时器正在运行，则即使本来配置的持续时间定时器超时(即on duration时间结束)，终端设备依然需要继续检测PDCCH，直到非激活定时器超时，如图7所示。
在DRX机制中，还有其它一些定时器，例如DRX下行重传定时器(也可以称为drx-retransmissiontimerDL)/DRX上行重传定时器(也可以称为drx-retransmissiontimerUL)。如果上述定时器中(包括持续时间定时器、非激活定时器、DRX下行重传定时器或DRX上行重传定时器等)的任意一个正在运行，那么终端设备就会处于“激活时间(active time)”。在DRX机制中，如果终端设备处于“active time”，那么终端设备就需要检测PDCCH。需注意的是，可能还有其它一些情况会让终端设备处于“active time”，这里不再多描述。
在NR系统中，终端设备会工作在更大的射频与基带带宽。图8为DRX能耗示意图，对于DRX机制，在一个DRX cycle中，终端设备需要首先从睡眠状态唤醒，开启射频和基带电路，获取时频同步，然后在“on duration”时间段内检测PDCCH，这些过程需要不少能耗。而一般而言，数据传输在时间上往往具有突发性和稀疏性，如果在“on duration”时间段内基站对终端设备没有任何数据调度的话，那么对于终端设备而言就产生了不必要的能量消耗。而如果终端设备在持续时间定时器的运行时间内检测到PDCCH，如前面所描述，终端设备就会开启一个非激活定时器。考虑到调度数据的时延需求，非激活定时器的运行时间一般是远大于持续时间定时器的运行时间，在非激活定时器超时时，终端设备进入睡眠状态(其中，图8中的三角形所示的区域可以表示终端设备的能耗逐渐减小的过程)。当基站给终端设备进行一次数据调度，终端设备会开启/重置非激活定时器，则会在很长的一段的时间内继续检测PDCCH，而这段时间内基站对终端设备可能没有任何数据调度，那么对于终端设备而言同样产生了不必要的能量消耗。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，例如第一信号可以用于指示在接下来的时间里网络设备是否会有数据调度，如果网络设备在n个时刻之后的一段时间内不调度数据，则网络设备可以不发送第一信号，那么终端设备在n个时刻上就检测不到第一信号，此时终端设备在第二时间段内就可以不检测下行控制信道，从而减少终端设备做无用功的几率，也节省终端设备的功耗。
请参见图9，为本申请实施例的一种应用场景。在图9中包括一个网络设备以及一个终端设备。其中，该网络设备例如工作在演进的通用移动通信系统陆地无线接入(evolved UMTS terrestrial radio access，E-UTRA)系统中，或者工作在NR系统。当然，在本申请实施例中，一个网络设备可以服务于多个终端设备，而一个网络设备所服务的全部或部分终端设备中的每个终端设备都可以通过本申请实施例的方式实现节能，图9只是以其中的一个终端设备为例。
图9中的网络设备例如为基站。其中，网络设备在不同的系统对应不同的设备，例如在第四代移动通信技术(the 4 th generation，4G)系统中可以对应eNB，在5G系统中对应5G中的网络设备，例如gNB。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种信道检测方法，请参见图10，为该方法的流程图。在下文的介绍过程中，以该方法应用于图9所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第一通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。对于第二通信装置也是同样，第二通信装置可以是网络设备或能够支持网络设备实现该方法所需的功能的通信装置，或者第二通信装置可以是终端设备或能 够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他通信装置，例如芯片系统。且对于第一通信装置和第二通信装置的实现方式均不做限制，例如第一通信装置可以是网络设备，第二通信装置是终端设备，或者第一通信装置和第二通信装置都是网络设备，或者第一通信装置和第二通信装置都是终端设备，或者第一通信装置是网络设备，第二通信装置是能够支持终端设备实现该方法所需的功能的通信装置，等等。其中，网络设备例如为基站。
为了便于介绍，在下文中，以该方法由网络设备和终端设备执行为例，也就是，以第一通信装置是网络设备、第二通信装置是终端设备为例。如果将本实施例应用在图9所示的网络架构，下文中所述的用于执行图10所示的实施例的网络设备可以是图9所示的网络架构中的网络设备，下文中所述的终端设备可以是图9所示的网络架构中的终端设备。
S101、终端设备在一个检测周期内的n个传输机会上检测第一信号，n为正整数；
S102、当所述终端设备在所述n个传输机会中的至少一个传输机会上检测到第一信号时，所述终端设备在所述检测周期中的第一时间段内检测下行控制信道和/或第二信号；或者，当所述终端设备在所述n个传输机会上均未检测到第一信号，所述终端设备在所述检测周期内不检测下行控制信道。
在本申请实施例中，网络设备可以配置终端设备检测第一类型的信号，其中，类型为第一类型的信号可称为第一信号，或者称为第一唤醒信号(wake up signal，WUS)，或者称为第一节能(power saving)信号。作为一种可选的实施方式，网络设备还可以配置终端设备检测第二类型的信号，其中，类型为第二类型的信号可称为第二信号，或者称为第二WUS信号，或者称为第二节能信号。也就是说，网络设备可以只配置终端设备检测第一类型的信号，那么终端设备只会检测第一信号，或者可以配置终端设备检测第一类型的信号和第二类型的信号，那么终端设备会检测第一信号和第二信号。例如，第一信号可以是UE特定(UE specific)信号，也就是针对一个终端设备的信号，或者也可以是UE组特定(UE-group specific)信号，也就是针对一个终端设备组中的每个终端设备的信号，同理，第二信号可以是UE特定信号，或者也可以是UE组特定信号，具体的不做限制。
例如，终端设备可以按照检测一定的检测周期来检测第一信号，例如一个检测周期的时长为第一时长，则终端设备可以每隔第一时长检测第一信号，例如可以将第一时长表示为P1，也就是说，终端设备可以按照周期P1检测第一信号，在每次检测时，终端设备可以检测n个传输机会(occasion)上的第一信号，或者说终端设备可以在n个传输机会上检测第一信号。其中，n的值可以通过高层信令半静态配置给终端设备，高层信令例如为RRC信令或媒体接入控制(media access control，MAC)层信令等。
作为一种实施方式，n个传输机会可以是n个连续的传输机会，也就是说n个传输机会是连续的。例如，n个传输机会可以是一个时隙内的连续的n个OFDM符号，如图11A所示，网络设备可以在这n个传输机会中的每个传输机会上均发送第一信号，从而提高第一信号的可靠性以及覆盖能力，或者网络设备也可以只在这n个传输机会中的部分传输机会上发送第一信号，图11A以n＝2为例；或者，这n个传输机会可以位于多个连续的时隙中，虽然n个传输机会所在的时隙连续，但这n个传输机会之间可能不连续，如图11B所示，但是在这种情况下，也认为n个传输机会是n个连续的传输机会。网络设备可以在n个传输机会所在的多个时隙中的任意一个或多个时隙上发送第一信号，从而提升网络设备调度数据的灵活性。其中，如果n个传输机会位于多个时隙中，则n个传输机会所在的时 隙的数量可以小于或等于n，例如n个传输机会所在的时隙的数量等于n，则一个传输机会位于一个时隙中，或者，n个传输机会所在的时隙的数量小于n，则可能有多个传输机会位于一个时隙中，且不同的时隙所包括的传输机会的数量可能相同也可能不同，具体的不做限制。令n个传输机会是连续的传输机会，更加便于终端设备的检测，降低终端设备的检测复杂度。
或者，作为另一种实施方式，n个传输机会也可以是n个不连续的传输机会，例如n个传输机会之间两两都不连续，或者n个传输机会之间有至少两个相邻的传输机会不连续。例如，n个传输机会可以是一个时隙内的不连续的n个OFDM符号，或者，n个传输机会可以位于多个不连续的时隙中，具体的不做限制。
在本申请实施例中，在网络设备有数据调度时，可以发送第一信号，也可以认为第一信号是节能信号。那么，如果终端设备在一个检测周期内的n个传输机会上均未检测到第一信号，也就表明网络设备在接下来的时间里没有数据调度，或者表明终端设备需要节能，则终端设备可以进入“睡眠(或称为睡眠)”状态，无需检测下行控制信道，也无需检测第二信号，直到下一个检测周期到来，终端设备再在下一个检测周期内的n个传输机会上检测第一信号。通过这种方式使得终端设备实现节能。
而如果终端设备在一个检测周期内的n个传输机会中的至少一个传输机会上检测到第一信号，那么终端设备可以在第一时间段内继续检测，例如终端设备可以在第一时间段内检测下行控制信道和第二信号，或者在第一时间段内检测第二信号，或者在第一时间段内检测下行控制信道。例如，如果第一信号是UE特定信号，那么终端设备可以在第一时间段内检测下行控制信道和第二信号，或者在第一时间段内检测第二信号，或者在第一时间段内检测下行控制信道，而如果第一信号是UE组特定信号，那么终端设备可以在第一时间段内检测第二信号，因为如果是UE组特定信号，则网络设备可能不会同时“唤醒”该组所有终端设备来接收下行控制信道，因此终端设备在第一时间段内可以先检测第二信号。当然这只是举例，具体的不限于此，例如第一信号是UE组特定信号，终端设备也是可以在第一时间段内检测下行控制信道和第二信号，或者在第一时间段内检测第二信号，或者在第一时间段内检测下行控制信道。
其中，图10以网络设备向终端设备发送了第一信号为例，可参考图10中的S103。由于网络设备不一定会向终端设备发送第一信号，因此S103通过虚线表示。网络设备发送第一信号和终端设备检测第一信号，这两个步骤的先后顺序可能是不确定的，例如网络设备可能先发送第一信号，终端设备再检测第一信号，或者终端设备也有可能在网络设备发送第一信号的同时检测第一信号，或者终端设备还有可能在网络设备发送第一信号之前就开始检测第一信号，具体的不做限制。
图10也以网络设备向终端设备发送了第二信号为例，可参考图10中的S104。由于网络设备也不一定会向终端设备发送第二信号，因此S104通过虚线表示。另外，网络设备发送第一信号和终端设备检测第二信号，这两个步骤的先后顺序可能是不确定的，例如网络设备可能先发送第一信号，终端设备检测第一信号，然后网络设备发送第二信号，终端设备检测第二信号，当然，具体的不做限制。同理，网络设备发送第二信号和终端设备检测第二信号，这两个步骤的先后顺序可能是不确定的，例如网络设备可能先发送第二信号，终端设备再检测第二信号，或者终端设备也有可能在网络设备发送第二信号的同时检测第二信号，或者终端设备还有可能在网络设备发送第二信号之前就开始检测第二信号，具体 的不做限制。
网络设备在发送第二信号时也可以周期性发送，则终端设备可以在第一定时器的定时时长内(或者为第一定时器的运行时间内)周期性检测第二信号，第二信号的检测周期的长度和第一信号的检测周期的长度可以相等，或者也可以不相等，例如已经将第一信号的检测周期用P1表示，再将第二信号的检测周期的长度用P2表示，则P2可以小于或等于P1。其中，第二信号的检测周期可以由终端设备检测的DCI格式(format)1-1/DCI format 0-1(或者为其它DCI格式，例如DCI格式0-0/1-0)所在的搜索空间集合的检测周期(或者说搜索空间集合的传输机会(occasion))确定，那么终端设备可以同步检测下行控制信道和第二信号，检测效率较高，或者，第二信号的检测周期也可以是第二信号所关联的搜索空间集合的检测周期，例如网络设备可以配置与第二信号所关联的搜索空间集合的索引号。
为了避免混乱，下文将分别介绍终端设备的不同的检测情况。
1、终端设备在检测到第一信号时的第一种实施方式，终端设备检测下行控制信道和第二信号。
在这种实施方式下，如果终端设备在n个传输机会中的一个传输机会上第一次检测到第一信号，那么终端设备可以启动第一定时器，第一时间段可通过第一定时器来计时，换句话说，第一定时器的计时时长就是第一时间段的长度。另外，网络设备也可以启动第一定时器。其中，终端设备第一次检测到第一信号的传输机会可能是n个传输机会中的任意一个传输机会。终端设备可以在第一次检测到第一信号后立刻启动第一定时器；或者，终端设备也可以在第一次检测到第一信号之后的预定义的时域位置启动第一定时器，例如预定义的时域位置可以是与第一次检测到第一信号的传输机会所在的时隙之间的距离为m的时隙，m大于或等于0，如果m＝0，那么终端设备也就是在第一次检测到第一信号的时隙启动第一定时器；或者，终端设备无论在n个传输机会中的哪个传输机会上检测到第一信号，都可以在n个传输机会结束后再启动第一定时器，例如终端设备可以在n个传输机会之后的预定义的时域位置启动第一定时器，例如预定义的时域位置可以是与n个传输机会中在时域上的最后一个传输机会所在的时隙之间的距离为m的时隙，m大于或等于0，例如m＝0，那么终端设备就是在n个传输机会中的最后一个传输机会所在的时隙启动第一定时器，或者m＝1，终端设备就是在n个传输机会中的最后一个传输机会所在的时隙之后的第一个时隙启动第一定时器，等等；或者，由于在这种实施方式中终端设备在第一时间段内还需要检测下行控制信道，因此终端设备也可以在与n个传输机会中的最后一个传输机会之间的距离最近的第一时刻启动第一定时器，其中，第一时刻是指终端设备检测搜索空间集合的时刻，也就是说，终端设备可能在n个传输机会之后的多个时刻都可以检测搜索空间集合，那么终端设备可以在用于检测搜索空间集合的时刻中，选择与n个传输机会中的最后一个传输机会之间的距离最近的时刻启动第一定时器，这样在第一时间段内，终端设备可以直接检测下行控制信道，使得检测较为及时。具体的，终端设备究竟在何时启动第一定时器，本申请实施例不做限制。
在这种实施方式下，终端设备在第一定时器的定时时长内是否检测到第二信号，可以并不影响终端设备对于下行控制信道的检测。例如，终端设备在第一时间段内是检测下行控制信道和第二信号，在尚未检测到第二信号时，终端设备可以继续对下行控制信道进行检测，而在检测到第二信号时，或者在检测到第二信号，且第二信号指示重置第一定时器 (或指示继续检测下行控制信道)，也可以认为此时第二信号指示的是“激活(active)”或“唤醒(wake up)”状态，终端设备还是可以继续对下行控制信道进行检测。
但，如果终端设备在第一时间段内尚未检测到第二信号，终端设备虽然继续对下行控制信道进行检测，而第一定时器的定时时长却不会改变，第一定时器会继续运行，如果直到第一定时器超时，也就是到第一时间段结束，终端设备都未检测到第二信号，则终端设备对下行控制信道和第二信号的检测也就结束，终端设备会停止检测下行控制信道和第二信号。
而如果终端设备在第一时间段内检测到了第二信号，或者终端设备在第一时间段内检测到了第二信号且第二信号指示重置第一定时器(或者，第二信号指示继续检测下行控制信道)，终端设备可以继续对下行控制信道进行检测，并且终端设备还会重置第一定时器，也就是对第一定时器进行清零，使得第一定时器重新开始计时，终端设备在重置后的第一定时器的定时时长内继续检测下行控制信道和第二信号。其中，网络设备也会重置第一定时器，例如可以在重置后的第一定时器的定时时长内发送下行控制信道和/或第二信号，当然也可以既不发送下行控制信道也不发送第二信号。如果终端设备在重置后的第一定时器的定时时长内检测到了第二信号，或者终端设备在重置后的第一定时器的定时时长内检测到了第二信号且第二信号指示重置第一定时器(或者，第二信号指示继续检测下行控制信道)，终端设备可以继续对下行控制信道进行检测，并且终端设备还会再次重置第一定时器，也就是对第一定时器进行清零，使得第一定时器再次重新开始计时，终端设备在再次重置后的第一定时器的定时时长内继续检测下行控制信道和第二信号，其中，网络设备也会再次重置第一定时器，例如可以在重置后的第一定时器的定时时长内发送下行控制信道和/或第二信号，当然也可以既不发送下行控制信道也不发送第二信号，等等，以此类推。
在网络设备有数据调度时，可以发送第二信号，也可以认为第二信号是节能信号。例如，如果网络设备的数据调度在第一时间段内即可实现，则网络设备可以无需发送第二信号，则终端设备在第一时间段内检测不到第二信号，在第一时间段结束时终端设备就会停止检测下行控制信道和第二信号，而此时网络设备也已经完成了发送，终端设备也完成了对网络设备发送的所有下行控制信道的检测，且终端设备在一定程度上实现了节能。或者，如果网络设备的数据调度在第一时间段内无法完成，需要延长终端设备的接收时间，则网络设备可以发送第二信号，或者，网络设备发送第二信号，且第二信号指示重置第一定时器(或者，指示继续检测下行控制信道)，终端设备根据第二信号可以重置第一定时器，并在重置后的第一定时器的定时时长内检测下行控制信道，网络设备也可以重置第一定时器，并在重置后的第一定时器的定时时长内发送下行控制信道，当然也可以不发送下行控制信道。可见，通过发送第二信号，可以拉长终端设备检测下行控制信道的时间长度，使得终端设备能够较为完整地检测到网络设备所发送的下行控制信道。
还有一种情况，网络设备发送第二信号，且第二信号指示不重置第一定时器(或者，指示暂停检测下行控制信道)，也可以认为此时第二信号指示的是“睡眠(sleep)”状态，那么终端设备在检测到第二信号时，可以停止检测下行控制信道，而终端设备可能不适宜于长久停止检测下行控制信道，因此终端设备可以在第三时间段内停止检测下行控制信道，而且终端设备在第三时间段内可以不检测第二信号，即如果第二信号的传输机会出现在第三时间段内时，UE可以在该传输机会上不检测第二信号。第三时间段可以认为是终端设备的“睡眠时间(sleep duration)”，终端设备在第三时间段内可以进入“睡眠”状态。其 中，“睡眠(sleep)”状态可以是指终端设备停止检测下行控制信道和第二信号的状态。第三时间段的长度可以通过高层信令配置，或者可以通过协议规定，或者也可以由用于指示不重置第一定时器(或者，指示暂停检测下行控制信道)的第二信号指示。而在第三时间段内，终端设备可以保持第一定时器继续运行，那么如果第三时间段在第一定时器超时之前结束，也就是终端设备在第一定时器超时之前醒来，则终端设备可以在第一定时器剩余的计时时间内继续检测下行控制信道和第二信号，而如果第三时间段在第一定时器超时时结束，或者在第一定时器超时之后才能结束，则终端设备在第一定时器超时时停止检测下行控制信道和第二信号。
其中，网络设备可以在有数据调度时发送第二信号(第二信号可以作为节能信号)，在这种情况下，对于第二信号所承载的信息并不作限制，那么，如果网络设备不发送第二信号，也就是终端设备只要检测不到第二信号，就不会重置第一定时器，在第一定时器超时时，终端设备就会停止检测下行控制信道和第二信号；而如果网络设备发送第二信号，终端设备检测到第二信号时就会重置第一定时器，并继续检测下行控制信道。第二信号的这种实现方式较为简单，终端设备根据是否检测到第二信号就可以确定应如何操作。
或者，网络设备可以通过第二信息所承载的信息来指示是否进行数据调度(或者作为节能信号)，在这种情况下，网络设备可以发送第二信号，第二信号承载的信息不同则可以指示不同的情况，例如第二信号承载1比特(bit)的信息，如果这1比特的取值为“0”，表明不重置第一定时器(或者暂停检测下行控制信道)，如果这1比特的取值为“1”，表明重置第一定时器(或者继续检测下行控制信道)。例如，网络设备发送第二信号且第二信号指示不重置第一定时器(或者指示暂停检测下行控制信道)，则终端设备检测到第二信号且确定第二信号指示不重置第一定时器(或者指示暂停检测下行控制信道)，终端设备在第三时间段内停止检测下行控制信道；或者，网络设备发送第二信号且第二信号指示重置第一定时器(或者指示继续检测下行控制信道)，则终端设备检测到第二信号且确定第二信号指示重置第一定时器(或者指示继续检测下行控制信道)，终端设备重置第一定时器，并继续检测下行控制信道。第二信号的这种实现方式，可以指示更为明确。
在第一定时器的运行时间内，网络设备还有可能发送第一信号，例如第一信号是UE组特定信号，那么网络设备为了照顾到一组终端设备的需求，有可能会多次发送第一信号，则对于一个终端设备来说，即使已处在第一定时器的运行时间内，还是可以接收网络设备发送的第一信号。但本申请实施例中，为了避免终端设备的混乱，可以使得终端设备在第一定时器运行时不检测第一信号，也就是说，在第一定时器的运行时间内，终端设备不检测第一信号，即使网络设备发送了第一信号，终端设备也不接收。
作为一种实施方式，网络设备可以通过第一信号指示第一时间段的长度，或者第一时间段的长度也可以由协议规定。另外，第一定时器在重置之后还会有相应的定时时长，而第一定时器重置之后的定时时长，和第一定时器在重置之前的定时时长，可以相等，也可以不相等，具体的不做限制。第一定时器在重置之后的定时时长如果与第一定时器在重置之前的定时时长不相等，那么第一定时器在重置之后的定时时长可以由网络设备指示，或者通过协议规定等。
作为一种实施方式，网络设备可以通过第一信号指示第一时间段的长度，UE进入第一时间段后，如果检测到第二信号或下行控制信道就启动或重置第一定时器，所述第一定时器的长度与第一时间段的长度，可以相等，也可以不相等。
可参考图12，为在第一种实施方式下，终端设备检测第一信号和第二信号的过程的一种示例。图12中以n＝2为例，终端设备在图12左边所示的2个传输机会上检测第一信号，如果在这2个传输机会上未检测到第一信号，则终端设备会进入睡眠状态，直到下一个检测周期到来，终端设备再在下一个检测周期内的2个传输机会上检测第一信号，下一个检测周期的2个传输机会为图12右边所示的2个传输机会。而如果终端设备在这两个传输机会上的一个传输机会上检测到了第一信号，终端设备会启动第一定时器，以进入第一时间段。在第一时间段，终端设备检测下行控制信道，且以周期P2检测第二信号，图12中的斜线框所示的位置就表示终端设备检测第二信号的位置。例如第一次没检测到第二信号，则终端设备继续检测下行控制信道，保持第一定时器继续运行，而在第二次检测到了第二信号，且第二信号指示继续检测下行控制信道(在图12中表示为第二信号指示检测下行控制信道，在本申请实施例中，指示“继续检测下行控制信道”和指示“检测下行控制信道”，可以理解为相同的概念，二者可互换)，则终端设备重置第一定时器，并在重置的第一定时器的定时时长内继续检测下行控制信道，以及检测第二信号。在第三次又检测到了第二信号，且第二信号指示暂停检测下行控制信道，则终端设备停止检测下行控制信道，进入睡眠状态。例如终端设备在从睡眠状态醒来后第一定时器还未超时，则终端设备继续检测下行控制信道和第二信号，直到第一定时器超时时，终端设备停止检测下行控制信道和第二信号。从第一时间段开始，直到第一定时器超时之前，即第一定时器的所有运行时间，都认为是终端设备的“激活时间(active time)”。
2、终端设备在检测到第一信号时的第二种实施方式，终端设备检测第二信号。
在这种实施方式下，如果终端设备在n个传输机会中的一个传输机会上第一次检测到第一信号，那么终端设备可以启动第一定时器，第一时间段就用于通过第一定时器来计时，换句话说，第一定时器的计时时长就是第一时间段的长度。其中，终端设备第一次检测到第一信号的传输机会可能是n个传输机会中的任意一个传输机会，关于终端设备启动第一定时器的时机，可以参考第1点中对于终端设备在检测到第一信号时的第一种实施方式中的相关描述，不多赘述。
在这种实施方式下，终端设备在第一定时器的定时时长内是否检测到第二信号，会影响终端设备对于下行控制信道的检测。例如，终端设备在第一时间段内检测第二信号，在尚未检测到第二信号时，终端设备不检测下行控制信道，而在检测到第二信号时，或者在检测到第二信号，且第二信号指示重置第一定时器(或指示检测下行控制信道)，也可以认为此时第二信号指示的是“激活(active)”状态，终端设备可以重置第一定时器，且开始检测下行控制信道。其中，“激活(active)”状态可以是指重置第一定时器，且开始检测下行控制信道的状态。当然，由于第二信号是周期性发送的，终端设备在第一次检测到第二信号后，还可能再次检测到第二信号，如果终端设备再次检测到第二信号，或者终端设备再次检测到第二信号，且第二信号指示重置第一定时器(或指示检测下行控制信道)，则终端设备可以重置第一定时器，且继续检测下行控制信道。
如果直到第一定时器超时，也就是到第一时间段结束，终端设备都未检测到第二信号，则终端设备对第二信号的检测也就结束，终端设备会停止检测第二信号，在这种情况下，虽然终端设备还未检测下行控制信道，但由于已经不再检测第二信号，则相当于终端设备对下行控制信道的检测也就结束了。
而如果终端设备在第一时间段内第一次检测到了第二信号，或者终端设备在第一时间 段内第一次检测到了第二信号且第二信号指示重置第一定时器(或者，第二信号指示检测下行控制信道)，终端设备开始对下行控制信道进行检测，并且终端设备还会重置第一定时器，也就是对第一定时器进行清零，使得第一定时器重新开始计时，终端设备在重置后的第一定时器的定时时长内开始检测下行控制信道，也可以继续检测第二信号。之后，如果终端设备在重置后的第一定时器的定时时长内检测到了第二信号，或者终端设备在重置后的第一定时器的定时时长内检测到了第二信号且第二信号指示重置第一定时器(或者，第二信号指示检测下行控制信道)，终端设备可以继续对下行控制信道进行检测，并且终端设备还会再次重置第一定时器，也就是对第一定时器进行清零，使得第一定时器再次重新开始计时，终端设备在再次重置后的第一定时器的定时时长内继续检测下行控制信道，也继续检测第二信号，以此类推。
网络设备在有数据调度时，可以发送第二信号，可以认为第二信号是节能信号。例如，如果网络设备在第一时间段内无数据调度，则网络设备可以无需发送第二信号，则终端设备在第一时间段内检测不到第二信号，也就不会检测下行控制信道，使得终端设备在一定程度上实现了节能。或者，如果网络设备有数据调度，且数据调度在第一时间段内无法完成，需要延长终端设备的接收时间，则网络设备可以发送第二信号，或者，网络设备发送第二信号，且第二信号指示重置第一定时器(或者，指示检测下行控制信道)，终端设备根据第二信号可以重置第一定时器，并在重置后的第一定时器的定时时长内检测下行控制信道，可见，通过发送第二信号，可以拉长终端设备检测下行控制信道的时间长度，使得终端设备能够较为完整地检测到网络设备所发送的下行控制信道。
还有一种情况，网络设备发送第二信号，且第二信号指示不重置第一定时器(或者，指示不检测下行控制信道，或指示暂停检测下行控制信道)，也可以认为此时第二信号指示的是“睡眠”状态，那么终端设备在检测到第二信号时，可以停止检测下行控制信道，而终端设备可能不适宜于长久停止检测下行控制信道，因此终端设备可以在第三时间段内停止检测下行控制信道，第三时间段可以认为是终端设备的“睡眠时间”，终端设备在第三时间段内可以进入“睡眠”状态。第三时间段的长度可以通过高层信令配置，或者可以通过协议规定，或者也可以由用于指示不重置第一定时器(或者，指示不检测下行控制信道，或指示暂停检测下行控制信道)的第二信号指示。而在第三时间段内，终端设备可以保持第一定时器继续运行，那么如果第三时间段在第一定时器超时之前结束，也就是终端设备在第一定时器超时之前醒来，则终端设备可以在第一定时器剩余的计时时间内继续检测第二信号，而如果第三时间段在第一定时器超时时结束，或者在第一定时器超时之后才能结束，则终端设备在第一定时器超时时停止检测下行控制信道和第二信号。
其中，网络设备可以通过发送第二信号来指示数据调度(或者作为节能信号)，在这种情况下，对于第二信号所承载的信息并不作限制，那么，如果网络设备不发送第二信号，也就是终端设备只要检测不到第二信号，就不会重置第一定时器，也不检测下行控制信道，在第一定时器超时时，终端设备就会停止检测第二信号；而如果网络设备发送第二信号，终端设备检测到第二信号时就会重置第一定时器，并检测下行控制信道。第二信号的这种实现方式较为简单，终端设备根据是否检测到第二信号就可以确定应如何操作。
或者，网络设备可以通过第二信息所承载的信息来指示是否进行数据调度(或者作为节能信号)，在这种情况下，网络设备可以发送第二信号，第二信号承载的信息不同则可以指示不同的情况，例如第二信号承载1比特的信息，如果这1比特的取值为“0”，表明 不重置第一定时器(或者，指示不检测下行控制信道，或指示暂停检测下行控制信道)，如果这1比特的取值为“1”，表明重置第一定时器(或者检测下行控制信道)。例如，网络设备发送第二信号且第二信号指示不重置第一定时器(或者，指示不检测下行控制信道，或指示暂停检测下行控制信道)，则终端设备检测到第二信号且确定第二信号指示不重置第一定时器(或者，指示不检测下行控制信道，或指示暂停检测下行控制信道)，终端设备在第三时间段内停止检测下行控制信道；或者，网络设备发送第二信号且第二信号指示重置第一定时器(或者指示检测下行控制信道)，则终端设备检测到第二信号且确定第二信号指示重置第一定时器(或者指示检测下行控制信道)，终端设备重置第一定时器，并检测下行控制信道。第二信号的这种实现方式，可以指示更为明确。
在第一定时器的运行时间内，网络设备还有可能发送第一信号，例如第一信号是UE组特定信号，那么网络设备为了照顾到一组终端设备的需求，有可能会多次发送第一信号，则对于一个终端设备来说，即使已处在第一定时器的运行时间内，还是可以接收网络设备发送的第一信号。但本申请实施例中，为了避免终端设备的混乱，可以使得终端设备在第一定时器运行时不检测第一信号，也就是说，在第一定时器的运行时间内，终端设备不检测第一信号，即使网络设备发送了第一信号，终端设备也不接收。
作为一种实施方式，网络设备可以通过第一信号指示第一时间段的长度，或者第一时间段的长度也可以由协议规定。另外，第一定时器在重置之后还会有相应的定时时长，而第一定时器重置之后的定时时长，和第一定时器在重置之前的定时时长，可以相等，也可以不相等，具体的不做限制。第一定时器在重置之后的定时时长如果与第一定时器在重置之前的定时时长不相等，那么第一定时器在重置之后的定时时长可以由网络设备指示，或者通过协议规定等。
作为一种实施方式，网络设备可以通过第一信号指示第一时间段的长度，UE进入第一时间段后，如果检测到第二信号就启动或重置第一定时器，所述第一定时器的长度与第一时间段的长度，可以相等，也可以不相等。
在第二种实施方式下，终端设备检测第一信号和第二信号的过程的一种示例也可以参考图12。图12中以n＝2为例，终端设备在图12左边所示的2个传输机会上检测第一信号，如果在这2个传输机会上未检测到第一信号，则终端设备会进入睡眠状态，直到下一个检测周期到来，终端设备再在下一个检测周期内的2个传输机会上检测第一信号，下一个检测周期的2个传输机会为图12右边所示的2个传输机会。而如果终端设备在这两个传输机会上的一个传输机会上检测到了第一信号，终端设备会启动第一定时器，以进入第一时间段。在第一时间段，终端设备以周期P2检测第二信号，图12中的斜线框所示的位置就表示终端设备检测第二信号的位置。例如第一次没检测到第二信号，则终端设备不检测下行控制信道，保持第一定时器继续运行，而在第二次检测到了第二信号，且第二信号指示检测下行控制信道，则终端设备重置第一定时器，并在重置的第一定时器的定时时长内检测下行控制信道，以及检测第二信号。在第三次又检测到了第二信号，且第二信号指示暂停检测下行控制信道，则终端设备停止检测下行控制信道，进入睡眠状态。例如终端设备在从睡眠状态醒来后第一定时器还未超时，则终端设备继续检测第二信号，直到第一定时器超时时，终端设备停止检测下行控制信道和第二信号。从第一时间段开始，直到第一定时器超时之前，都认为是终端设备的“激活时间”。
3、终端设备在检测到第一信号时的第三种实施方式，终端设备检测下行控制信道。
在这种实施方式下，网络设备只配置终端设备检测第一类型的信号，也就是检测第一信号，网络设备不会发送第二信号，终端设备也不会检测第二信号。
在这种实施方式下，如果终端设备在n个传输机会中的一个传输机会上第一次检测到第一信号，那么终端设备可以启动第一定时器，第一时间段就用于通过第一定时器来计时，换句话说，第一定时器的计时时长就是第一时间段的长度。其中，终端设备第一次检测到第一信号的传输机会可能是n个传输机会中的任意一个传输机会，关于终端设备启动第一定时器的时机，可以参考第1点中对于终端设备在检测到第一信号时的第一种实施方式中的相关描述，不多赘述。
网络设备可以通过第一信号指示第一时间段的长度，那么终端设备在检测到第一信号后(例如在第一次检测到第一信号后)就可以根据第一信号确定第一时间段的时长，或者第一时间段的时长也可以通过协议规定，或者可以由网络设备通过其他信令(例如高层信令)指示。对于第一时间段的长度也不做限制，例如可以是1个时隙或多个时隙，或者也可以是一个符号或多个符号。
例如第一信号可以指示第一时间段的长度，或者说是指示第一时间段。例如第一信号可以通过1个比特来指示第一时间段，如果这1比特取值为“1”，就表明第一时间段是周期P1的前半个周期，而如果这1比特取值为“0”，就表明第一时间段是周期P1的后半个周期。或者，第一信号通过2个比特来指示第一时间段，这2个比特中的高位比特用于表示周期P1的前半个周期，这2个比特中的低位比特用于表示周期P1的后半个周期，如果这2个比特中的高位比特的取值为“1”，表明第一时间段是周期P1的前半个周期，而如果这2个比特中的低位比特的取值为“1”，就表明第一时间段是周期P1的后半个周期，当然，在这2个比特中的高位比特的取值为“1”时，这2个比特中的低位比特的取值就是“0”，在这2个比特中的低位比特的取值为“1”时，这2个比特中的高位比特的取值就是“0”。当然还可以在第一信号中通过更多的比特来指示第一时间段，或者也可以通过相同的比特但是不同的方式来指示第一时间段，等等，本申请实施例并不限制如何通过第一信号指示第一时间段。
可参考图13，为在第三种实施方式下，终端设备检测第一信号的过程的一种示例。图13中以n＝2为例，终端设备在图13左边所示的2个传输机会上检测第一信号，如果在这2个传输机会上未检测到第一信号，则终端设备会进入睡眠状态，直到下一个检测周期到来，终端设备再在下一个检测周期内的2个传输机会上检测第一信号，下一个检测周期的2个传输机会为图13右边所示的2个传输机会。而如果终端设备在这两个传输机会上的一个传输机会上检测到了第一信号，则终端设备可以进入第一时间段，其中第一时间段的长度是终端设备根据第一信号获得的。在第一时间段，终端设备检测下行控制信道，其中，终端设备也是按照搜索空间集合的检测周期来检测下行控制信道，搜索空间集合的检测周期是图13中的斜线框所示的位置，直到第一定时器超时时，终端设备停止检测下行控制信道。第一时间段可以认为是终端设备的“激活时间”。
如上介绍了终端设备在检测到第一信号时的三种实施方式，在具体应用中究竟选择哪种实施方式，可以由协议规定，或者由网络设备配置等。
在本申请实施例中，第一信号和第二信号都可以是基于序列生成的。第一信号可以是基于第一序列生成的，第二信号可以是基于第二序列生成的，第一序列属于第一序列集合，第二序列属于第二序列集合，第一序列集合可以是第二序列集合的子集。例如，第一序列 集合包括序列1，第二序列集合包括序列1和序列2。
或者，本申请实施例中的序列都是指调制之前的信息，那么，第一序列和第二序列可以是相同的序列，例如第一序列和第二序列都是序列1，但是在基于第一序列生成第一信号时可以采用第一调制方式，在基于第一序列生成第二信号时可以采用第二调制方式，第一调制方式和第二调制方式不同，也就是基于同一个序列、以不同的调制方式生成不同的信号，通过这种方式可以节省所需的序列。
或者，因为终端设备对第一信号和第二信号的检测时机是不同的，终端设备只会在n个传输机会上检测第一信号，而又只会在第一定时器的定时时长内检测第二信号，因此，第一序列和第二序列可以是相同的序列，而对于在生成相应的信号时的调制方式也不做限制，例如在基于第一序列生成第一信号时可以采用第一调制方式，在基于第一序列生成第二信号时也可以采用第一调制方式，因为终端设备会在不同的时机分别检测第一信号和第二信号，因此即使第一信号和第二信号完全相同，也不会影响终端设备的解析。也可以理解为，同一个序列可以对应不同的信号，而不同的信号的功能是不同的，例如该序列对应第一信号时，终端设备在接收第一信号后可以在第一时间段内检测下行控制信道和/或第二信号，或者，该序列对应第二信号时，终端设备在接收第二信号后可以检测下行控制信道，或者可以在第三时间段内进入“睡眠”状态等。例如，基于序列1生成第一信号，基于序列1生成第二信号，且采用的调制方式是相同的，那么，在序列1对应第一信号时，终端设备在接收第一信号后可以在第一时间段内检测下行控制信道和/或第二信号，或者，在序列1对应第二信号时，终端设备在接收第二信号后可以检测下行控制信道，或者可以在第三时间段内进入睡眠状态等。
或者，第一信号和第二信号也可以不是基于序列生成的，例如第一信号和第二信号都是信令的形式，也就是对信息域的比特进行信道编码后传输。例如，第一信号承载第一状态值，第二信号承载第二状态值，第一状态值属于第一状态值集合，第二信息状态值属于第二状态值集合，第一状态值集合为第二状态值集合的子集。例如第一信号所承载的第一状态值为2比特，第二信号所承载的第二状态值也为2比特，第一状态值集合[00]，第二状态值集合为[00,01,10,11]，可以看到，第一状态值集合是第二状态值集合的子集。例如，第一状态值为00，第二状态值也为00，则终端设备在接收第一状态值00后可以在第一时间段内检测下行控制信道和/或第二信号，终端设备在接收第二状态值00后可以检测下行控制信道，或者可以在第三时间段内进入睡眠状态等。或者，第一状态值为00，第二状态值为01，则终端设备在接收第一状态值00后可以在第一时间段内检测下行控制信道和/或第二信号，终端设备在接收第二状态值01后可以检测下行控制信道，或者可以在第三时间段内进入睡眠状态等。通过这种方式，第一信号和第二信号可以进行统一设计，即设计成同一信道或信号的形式，减少标准化的难度。
作为一种实施方式，本申请实施例中的第一信号和第二信号都是不与DRX周期绑定的，即UE在没有配置DRX机制的情况下，也可以配置检测第一信号和/或第二信号。也就是说，第一信号和第二信号都跟DRX周期无关，与DRX机制无关，这有助于提高网络设备调度的灵活性，而且无需等到DRX周期时终端设备才能实现节能，提升了终端设备的节能效果。
或者，作为一种实施方式，第一信号也可以与DRX机制相结合，那么在本申请实施例中，第一时间段的时间起始位置可以是一个DRX周期的时间起始位置，终端设备检测 第一信号的周期可以直接为DRX周期，在这种情况下，该DRX周期的on duration timer的计时时长是0ms，在该DRX周期的激活时间内，终端设备在该DRX周期的起始位置上只开启第一定时器，此时认为非激活定时器就没有了。或者，在这种情况下，在该DRX周期的激活时间内，终端设备在该DRX周期的起始位置上只开启第一定时器，此时认为on duration timer和非激活定时器都没有了。或者，第一定时器也可以是inactivity timer，inactivity timer在DRX周期的起始位置处启动，或者，只要终端设备检测到第一信号就启动inactivity timer，此时，on duration timer就没有了，或者，on duration timer的计时时长是0ms。其中，第一定时器的运行时间可以是该DRX周期的激活时间。
或者理解为，终端设备在检测到第一信号后，可以启动一个DRX周期，则第一时间段的时间起始位置就是该DRX周期的时间起始位置。在目前的DRX周期中，终端设备在进入一个DRX周期后会启动持续时间定时器，如果在持续时间定时器的计时时长内终端设备检测到了PDCCH，那么终端设备还会开启DRX机制中的非激活定时器，以在非激活定时器的定时时长内检测PDCCH。但是在本申请实施例中，第一时间段是通过第一定时器来计时的，也就是说，终端设备只需要在第一时间段的时间起始位置启动一个定时器即可，在后续的过程中可能会根据第二信号来重置第一定时器，但是无需再启动其他的定时器，可以理解为，本申请实施例中的第一定时器不是目前的DRX周期中的持续时间定时器，也不是非激活定时器，而是用第一定时器这一个定时器代替了原本的DRX周期中的持续时间定时器和非激活定时器，节省了定时器的数量，也简化了终端设备的节能过程。
