本发明涉及通信技术领域，尤其涉及一种信息检测方法及装置。
背景技术
为了降低终端设备的能耗，在无线通信，例如长期演进(long term evolution，LTE)系统中，已经引入了非连续接收(discontinuous reception，DRX)机制。终端设备的能耗开销主要集中在对物理下行控制信道(physical downlink control channel，PDCCH)的盲检测上，DRX机制可以让终端设备周期性地进入睡眠状态(或称为睡眠模式，sleep mode)而不对PDCCH进行盲检测，在需要进行盲检测的时候，则从睡眠状态中唤醒(wake up)，这样就可以使终端设备达到省电的目的。
当终端设备从睡眠状态中唤醒后，终端设备将会在一段时间内持续对PDCCH进行盲检测，该过程仍然存在耗能较大的问题。因此，如果能在保证PDCCH检测性能的前提下，减少这部分能耗开销，则能够为终端设备提供更长时间的续航能力。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合说明书附图以及具体的实施方式对本申请实施例中的技术方案进行详细的说明。
以下，对本申请实施例中的部分用语进行说明，以便于本领域技术人员理解。
1)终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备例如可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local  loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，该终端设备还可以包括可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。该终端设备还可以是虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
2)网络设备，例如包括基站，可以是指接入网中在空口通过一个或多个小区与终端设备通信的设备。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与网络的其余部分之间的路由器，其中网络的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等，也可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-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(fifth generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)，在一种网络结构中，网络设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点。本申请实施例并不限定。
在一种网络架构中，基站包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，基站包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
基站和终端之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol,SDAP)层。
基站可以由一个节点实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、和媒体接入控制(Media Access Control，MAC)等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，基站可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
可选的，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端，或者终端产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端或CU。以下实施例中如果涉及这种信令在DU和终端之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为无线接入网(RAN)侧的网络设备，此外，也可以将CU划分为核心网(CN)侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的基站。
3)DRX，在DRX机制下，终端设备在睡眠时间里会停止监听PDCCH。DRX分两种：空闲(IDLE)DRX和连接(CONNECTED)C-DRX。
IDLE DRX，也就是终端设备处于空闲状态的非连续性接收，由于终端设备处于空闲状态时，已经没有无线资源控制(radio resource control，RRC)连接以及终端设备的专有资源，因此在IDLE DRX下终端设备主要监听寻呼消息，只要定义好寻呼消息的周期，就可以达到非连续接收的目的。终端设备监听用户数据时，离开空闲态，例如从空闲状态先进入连接状态。
C-DRX，也就是终端设备处在RRC connected状态下的DRX，在C-DRX下，终端设备会周期性地盲检测候选PDCCH，如果在一段时间内检测不到PDCCH，终端设备就会进入停止(OFF)状态，在OFF状态下终端设备停止检测PDCCH，以降低终端设备的检测PDCCH的能耗。OFF状态又可以称为睡眠态。
4)下行控制信道，例如为PDCCH，或者为增强的物理下行控制信道(enhanced physical  downlink control channel，EPDCCH)，窄带物理下行控制信道(narrowband physical downlink control channel，NPDCCH)，或者可以是其他的下行控制信道。
5)时间单元，是一种时间单位。例如包括一个时隙(slot)或者一个子帧或者一个微时隙(mini-slot)或者一个正交频分复用((orthogonal frequency division multiplexing，OFDM)符号或者一毫秒(ms)或者分数毫秒(例如1/32ms)的时间单位，或者包括多个时隙或者多个子帧或者多个微时隙(mini-slot)或者多个OFDM符号或者若干毫秒(ms)或者若干分数毫秒的时间单位。
6)不连续接收的周期(DRX cycle)，一个DRX cycle等于终端设备的唤醒时间(ON-duration)和睡眠时间的总和，可以理解为，在每个DRX cycle内，终端设备会醒过来一段时间用于监听PDCCH。DRX cycle有两种，分别为DRX长周期和DRX短周期，DRX长周期是DRX短周期的整数倍。网络设备可以为终端设备配置DRX短周期和DRX长周期，当DRX短周期结束后，终端设备进入一次DRX长周期，网络设备也可以只为终端设备配置DRX长周期而不配置DRX短周期，DRX长周期和DRX短周期的配置情况根据实际使用需求确定。
7)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个，例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。
在现有技术中，为了节省终端设备的能耗，达到省电的目的，通常采用DRX机制让终端设备周期性地进入睡眠状态和唤醒状态，从而，终端设备仅在唤醒状态时，对PDCCH进行盲检测。然而，当终端设备从睡眠状态中唤醒，进入唤醒状态后，终端设备将会在一段时间内持续对PDCCH进行盲检测，该过程仍然存在耗能较大的问题。
鉴于此，提供本申请实施例的技术方案，在本申请实施例中，网络设备可以向终端设备发送用于指示是否检测控制信道的信号，则终端设备根据该信号的检测结果，通过控制定时器的状态来控制终端设备处于唤醒状态的时间，例如当终端设备确定该信号的检测结果指示不检测控制信道，则终端设备可以不开启用于唤醒终端设备的定时器，从而可以增加终端设备处于睡眠状态的时间，可以通过这种方式，在保证PDCCH检测性能的前提下，减少这部分能耗开销，可以提高终端设备的续航能力。
本申请实施例提供的技术方案可以应用于5G系统中，或者应用于LTE系统中，或者还可以应用于下一代移动通信系统或其他类似的通信系统，具体的不做限制。
下面介绍本申请实施例所应用的一种网络架构，请参考图1。
图1中的网络架构包括网络设备和终端设备，终端设备与网络设备无线连接。图1中的终端设备的数量只是举例，在实际应用中，网络设备可以为多个终端设备提供服务。
图1中的网络设备例如为无线接入网(radio access network，RAN)设备，例如基站。 其中，RAN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(4G)系统中可以对应eNB,在第五代移动通信技术(5G)系统中对应5G中的RAN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息检测方法，请参见图2，为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，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。
为便于介绍，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。
S201、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
具体来讲，网络设备在无线资源配置过程中，可以向终端设备发送DRX配置消息。该DRX配置消息中可以包括为终端设备配置的定时器的初始值，该配置的定时器可以包括以下定时器中的一种或多种：drx-on duration timer、drx-inactivity timer、drx-HARQ RTT timerDL、drx-HARQ RTT timerUL、drx-retransmission timerDL、drx-retransmission timerUL、drx-long cycle timer、drx-short cycle timer。当然，该DRX配置消息中还可以包括其他内容，在此不一一列举。
下面，对上述多个定时器进行介绍。
①持续时间定时器(drx-on duration timer)，用于指示终端设备在进入DRX周期后，连续的时间单元的个数。终端设备在这段时间内侦听PDCCH。该时间单元为1/32ms或1ms。
②非激活定时器(drx-inactivity timer)，用于指示在PDCCH指示了数据传输后，连续的时间单元的个数，或者可以理解为指示数据传输的控制信道之后终端设备检测控制信道的时间，也可以理解为指示在终端设备检测到指示数据传输的控制信道之后的连续的控制信道的时间单元的个数，或者可以理解为指示在终端设备检测到指示数据传输的下行控制信息(DCI)之后，终端设备检测控制信道的时间。终端设备在这个时间段内侦听PDCCH。该时间单元为1ms。
③下行混合自动重传往返时延定时器(drx-HARQ RTT timerDL)，用于指示下行重传接收之前最少的连续的时间单元的个数，也可以理解为最小的重传调度间隔，即用于指示下一个下行数据发送最早在多少个时间单元后出现，可以理解为，在该定时器运行期间，终端设备不侦听PDCCH。该时间单元为一个OFDM符号。
④上行混合自动重传往返时延定时器(drx-HARQ RTT timerUL)，用于指示上行重传接收之前最少的连续的时间单元的个数，也可以理解为最小的重传调度间隔，即用于指示下一个上行数据发送最早在多少个时间单元后出现，可以理解为，在该定时器运行期间， 网络设备不会收到上行数据。该时间单元为一个OFDM符号。
⑤下行重传定时器(drx-retransmission timerDL)，用于指示在下行数据重传接收之前，终端设备检测控制信道的时间，或者说，用于指示在下行数据重传接收之前连续的控制信道的时间单元的个数。终端设备在这段时间内需要侦听PDCCH。该时间单元为一个slot。
⑥上行重传定时器(drx-retransmission timerUL)，用于指示在上行数据重传接收之前，网络设备接收数据的时间，或者说，用于指示在上行数据重传接收之前连续的控制信道的时间单元的个数。该时间单元为一个slot。
⑦长周期定时器(drx-long cycle timer)，为DRX机制的长周期的生命周期，单位为ms。
⑧短周期定时器(drx-short cycle timer)，为DRX机制的短周期的生命周期，单位为ms。
对于以上任一定时器，该DRX配置消息中可以不包括定时器的初始值，例如，定时器的初始值可以是网络设备和终端设备预先约定的。该DRX配置消息可以是RRC消息，例如，该DRX配置消息可以是RRC建立消息或者RRC重建消息或RRC重配消息，还可以是MAC-CE消息，还可以是DCI信令，当然，也可以是其他类型的消息，在此不作限制。另外，在本申请实施例中，术语drx-on duration timer与on duration timer可被互换使用，drx-HARQ RTT timerDL与HARQ RTT timerDL可被互换使用。
另外，以上定时器，例如，drx-long cycle timer、drx-short cycle timer、on duration timer、drx-inactivity timer、HARQ RTT timer以及drx-retransmission timer，为LTE系统中使用的名称，当上述定时器应用于其他通信系统中，例如5G或者其他类型的通信系统中时，也可以使用其他名称，在本申请实施例中，不对定时器的名称进行限制。
当终端设备接收该DRX配置消息后，则启动DRX模式，进入DRX周期，如此，终端设备可以进入睡眠状态，以节省能耗。具体来讲，若终端设备通过网络设备给发送的DRX配置信息，确定网络设备为终端设备配置了DRX长周期和DRX短周期，或者网络设备仅为终端设备配置了DRX长周期，则终端设备可以进入DRX长周期中；若终端设备确定网络设备仅为终端设备配置了DRX短周期，则终端设备可以进入DRX短周期中，在此不作限制。当终端设备进入DRX长周期或DRX短周期后，则按照DRX配置进入睡眠或唤醒状态。为方便说明，以终端设备进入睡眠状态的时刻为第n毫秒(ms)为例。
S202、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
当终端设备进入睡眠状态后，终端设备会根据预设的条件确定启动on duration timer，从而终端设备由睡眠状态调整为唤醒状态。该预设的条件可以是DRX周期的使用公式，例如，终端设备执行S201进入DRX长周期，则判断当前时刻满足长周期使用公式时，启动on duration timer；或者，终端设备执行S201进入DRX短周期，则判断当前时刻满足短周期使用公式时，启动on duration timer，当然，该预设的条件也可以是其他条件，在此不作限制。
该长周期使用公式可以为[(SFN*10)+subframe number]mod(long DRX-Cycle)＝drxStartOffset，其中，SFN为当前子帧所在的系统帧号(system frame number，SFN)，mod为取余预算，subframe number为当前子帧的子帧号，long DRX-Cycle为长周期，drxStartOffset为启动drx-on duration timer的子帧与终端设备进入DRX长周期的子帧的偏移量。该短周期使用公式可以为：[(SFN*10)+subframe number]mod(shortDRX-Cycle)＝ (drxStartOffset)mod(shortDRX-Cycle)，其中，SFN为当前子帧所在的系统帧号，mod为取余预算，subframe number为当前子帧的子帧号，short DRX-Cycle为短周期，drxStartOffset为启动drx-on duration timer的时刻与终端设备进入DRX短周期的时刻的偏移量。当然，该长周期使用公式或者短周期使用公式也可以是其他形式，在此不作限制。
为方便说明，在下文中以终端设备确定在第n+4毫秒启动on duration timer为例。
当终端设备启动on duration timer后，终端设备则处于唤醒状态，并在该on duration timer运行时检测控制信道，检测是否有网络设备发送的下行控制信息(DCI)或者寻呼(paging)消息或者其他用于唤醒终端设备的消息。为方便说明，在后文的描述中，以该控制信道为PDCCH、终端设备在该控制信道检测即为检测DCI为例进行说明。
S203、网络设备发送第一DCI，终端设备检测第一DCI以及检测第一信号。
当终端设备进入DRX模式后，若网络设备需要向终端设备传输数据，则网络设备会在终端设备的on duration timer运行期间发送第一DCI，从而终端设备则在on duration timer运行期间接收该第一DCI。网络设备可以在on duration timer的第一次运行期间发送第一DCI，则终端设备在on duration timer的第一次运行期间便可以检测到第一DCI。网络设备也可以是在on duration timer的第N次运行期间发送第一DCI，N为大于或等于2的整数，从而当on duration timer第一次超时后，终端设备再次进入睡眠时间。直到再次满足长周期使用公式时，则再次启动on duration timer，并进入唤醒时间，从而继续检测DCI。为方便说明，下文中，以网络设备在on duration timer的第一次运行期间发送第一DCI为例。
在本申请实施例中，该第一DCI可以是指示数据传输的下行控制信息DCI，该传输的数据可以是下行(downlink，DL)数据、上行(uplink，UL)数据、边链路(sidelink，SL)数据中的任意一种，该数据可以是初始传输的数据，也可以是非初始传输的数据，在此不作限制。
在本申请实施例中，终端设备在检测到第一DCI的时刻，会同时检测第一信号，如图3所示，该第一信号的检测时刻与终端设备检测到第一DCI的检测时刻相同。该检测时刻是指相同时间单元，该时间单元例如为毫秒，则第一信号的检测时刻与终端设备检测到第一DCI的检测时刻相同，可以理解为，终端设备在第i毫秒内检测第一DCI和检测第一信号，i为大于或等于0的整数。具体来讲，终端设备可以在第i毫秒内的同一OFDM符号上检测第一DCI和检测第一信号，例如，终端设备在第i毫秒内的第2个OFDM符号上的第一频段上检测第一DCI，在第i毫秒内的第2个OFDM符号上的第二频段上检测第一信号。终端设备也可以是在第i毫秒内的不同的OFDM符号上检测第一DCI和检测第一信号，例如，终端设备在第i毫秒内的第一个OFDM符号上检测第一DCI，在第i毫秒内的第三个OFDM符号上检测第一信号，在本申请实施例中不作限制。在下文中，以终端设备可以在第i毫秒内的同一OFDM符号上检测第一DCI和检测第一信号为例。
下面，对第一信号进行说明。例如，网络设备在第n+5毫秒的第一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号上发送第一DCI，由于终端设备接收信息会有一定延迟，例如，延迟2个OFDM符号，从而终端设备在第n+5毫秒的第三个OFDM符号上接收该第一DCI。为方便说明，在下文中，可以忽略发送信号和接收信号之间的时延，以网络设备发送第一DCI的时刻与终端设备接收该第一DCI的时刻相同为例，也就是说，网络设备在第n+5毫秒上发送第一DCI，终端设备则在第n+5毫秒上接收该第一DCI。
具体来讲，该第一信号用于指示终端设备是否检测控制信道，以控制信道为PDCCH为例，可以理解为，该第一信号用于指示终端设备是否检测PDCCH。针对网络设备而言，第一信号用于指示终端设备是否检测控制信道，可以理解为，网络设备是否发送DCI，也就是说，若网络设备发送DCI，则终端设备检测控制信道，若网络设备不发送DCI，则终端设备不需要检测控制信道。
该第一信号可以是终端设备和网络设备预先约定的信号，例如，该第一信号的具体内容可以是网络设备与终端设备约定的内容，或者，该第一信号也可以是只包含特定包头的一个空包，在此不作限制。该第一信号还可以称为唤醒信号(wake up signal，WUS)，该WUS可以是控制信令，以DCI的形式承载在PDCCH上，该WUS可以是信号或导频的形式承载在物理下行共享信道(physical downlink shared channel，PDSCH)上，例如，该WUS可以为恒包络零自相关序列(const amplitude zero auto-corelation，CAZAC)，例如为Zadoff－Chu(ZC)序列、Frank序列、Golomb多相序列或Chirp序列等。在本申请实施例中，不对第一信号的具体形式进行限制。
另外，该第一信号可以具有二项性，也就是说，该第一信号可以用来指示终端设备检测控制信道，也可以用来指示终端设备不检测控制信道。例如，网络设备可以通过发送该第一信号和不发送该第一信号指示该二项性，网络设备确定在发送第一DCI之后还会继续发送DCI，则网络设备向终端设备发送该第一信号，终端设备在接收该第一信号后，则确定在第一DCI之后还会检测到DCI；若网络设备确定在发送第一DCI之后不会再发送DCI，则网络设备便不会发送该第一信号，则终端设备在检测该第一信号的时刻未接收该第一信号，则确定在第一DCI之后不会检测到DCI。或者，网络设备可以根据该第一信号的携带的内容指示该二项性，也就是说，不论网络设备在发送第一DCI之后是否会继续发送DCI，网络设备都会发送该第一信号，但是在不同的情况下，该第一信号中携带的内容不同。例如，网络设备通过第一信号的掩码来指示该二项性，网络设备和终端设备预先约定当第一信号中携带的掩码为掩码1时，代表网络设备在发送第一DCI之后还会继续发送DCI，且当第一信号中携带的掩码为掩码2时，代表网络设备在发送第一DCI之后不会再发送DCI，因此，当终端设备接收该第一信号后，则可以根据该第一信号中的掩码确定在第一DCI之后是否会检测到DCI。或者，网络设备也可以直接在第一信号中携带是否继续发送DCI的信息，终端设备在接收该第一信号后，根据该信息确定在第一DCI之后是否会检测到DCI。在本申请实施例中，不对第一信号的二项性指示方式进行限制。
由于第一信号的具体形式和二项性的指示方式不同，因此，终端设备检测该第一信号的方式，以及解读的第一信号的含义也不一样。终端设备的检测方式可以包括：若该第一信号承载在PDCCH上，则终端设备在PDCCH上检测该第一信号，若该第一信号承载在PDSCH上，则终端设备在PDSCH上检测该第一信号。因此，网络设备与终端设备可以预先约定第一信号的具体形式以及第一信号的二项性的指示方式，或者，由网络设备将该第一信号的具体形式以及第一信号的二项性的指示方式指示给终端设备，例如，可以通过S201中的DRX配置消息指示给终端设备，当然，也可以通过其他信息指示给终端设备，例如，可以在S202之前发送DCI将第一信号的具体形式以及第一信号的二项性的指示方式指示给终端设备，在此不作限制。
在本申请实施例中，以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。网络设备确定在发送第一DCI后不会再发送DCI， 则网络设备在第n+5毫秒上仅发送第一DCI，而不发送第一信号，从而终端设备在第n+5毫秒上接收该第一DCI且未检测到第一信号。
S204、终端设备根据第一信号的检测结果确定定时器的状态。
在本申请实施例中，该定时器用于在DRX模式下，延长终端设备监听PDCCH的时间，该定时器用于指示在接收到指示数据传输的下行控制信息(DCI)的时间单元之后，终端设备检测该控制信道的时间单元的个数，或者，该定时器用于指示在终端设备检测到指示数据传输的控制信道之后的连续的控制信道的时间单元的个数。在本申请实施例中，该指示数据传输的下行控制信息(DCI)以及指示数据传输的控制信道可以理解为第一DCI。也就是说，终端设备在该定时器的运行时间内检测该控制信道。为方便说明，在下文中，以时间单元为毫秒为例。
具体来讲，当终端设备检测到第一DCI且未检测到第一信号，则终端设备确定该定时器状态为关闭或者不开启该定时器或者关闭该定时器。需要说明的是，终端设备本应在检测到第一DCI的毫秒上开启该定时器，并在该定时器的运行时长内检测DCI，然而由于终端设备在该毫秒上未检测到该第一信号，也就是说，终端设备对第一信号的检测结果表示终端设备在该毫秒后不检测该控制信道，也就是说，网络设备后续不会发送DCI，在这种情况下，终端设备便停止该定时器，并将该定时器的计时重置为初始值，或者，终端设备不会开启该定时器。需要说明的是，终端设备在定时器的运行时长内检测DCI，可以是在定时器的运行时长内的每毫秒上检测DCI，也可以是按照预设的检测周期，例如，每隔一毫秒检测一次等，在本申请实施例中不限定终端设备检测DCI的方式。为方便描述，在下文中，以终端设备在每毫秒上检测DCI为例。
为方便说明，在下文中以该定时器为drx-inactivity timerDL为例。作为一种示例，终端设备在第n+5毫秒上检测到第一DCI，那么终端设备本应在第n+5毫秒上开启drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为3毫秒，那么终端设备本应在第n+6毫秒、第n+7毫秒以及第n+8毫秒上保持唤醒状态。但是，终端设备在第n+5毫秒上也对第一信号进行了检测且未检测到该第一信号，则终端设备在第n+5毫秒上停止drx-inactivity timerDL的计时，并将drx-inactivity timerDL的计时重置为初始值3毫秒，相当于drx-inactivity timerDL没有开启，这样，终端设备便不会因为drx-inactivity timerDL的原因，在第n+6毫秒、第n+7毫秒以及第n+8毫秒上保持唤醒状态。
S205、网络设备发送第一信号，终端设备检测到第一信号。
在本申请实施例中，虽然终端设备在检测到第一DCI时未检测到第一信号，且确定不开启drx-inactivity timerDL。但由于终端设备的on duration timer可能还处于运行状态，例如，on duration timer的初始值为6毫秒，即终端设备在第n+4毫秒～第n+10毫秒均处于唤醒状态，因此，终端设备在第n+5毫秒上未检测该第一信号后，仍然处于唤醒状态，仍然保持对PDCCH的侦听。
需要说明的是，第一信号指示终端设备是否检测控制信道是有时限的，也就是说，第一信号可以指示在一个时间段内，终端设备是否检测控制信道。例如，网络设备可以配置发送第一信号的周期，或者网络设备可以与终端设备约定发送第一信号的周期，例如，该周期可以是4毫秒，则网络设备每隔4毫秒确定是否发送第一信号，终端设备在唤醒状态每隔4毫秒检测第一信号。这样，网络设备在第n+5毫秒上未发送第一信号，表示网络设备在第n+5毫秒～第n+9毫秒上不会发送DCI。由于终端设备在第n+5毫秒上未检测到第 一信号，因此，终端设备在第n+5毫秒～第n+8毫秒上不会检测到DCI。
以发送第一信号的周期为4毫秒，则网络设备在第n+10毫秒上确定在下一个周期内会发送DCI，则网络设备在第n+10毫秒上发送第一信号，终端设备在第n+10毫秒上检测到第一信号。
S206、终端设备根据第一信号的检测结果确定drx-inactivity timerDL的状态。
该定时器与S204中相同，在此不再赘述。
具体来讲，当终端设备在第n+10毫秒上检测到第一信号，则终端设备确定开启该drx-inactivity timerDL，并将该drx-inactivity timerDL的计时设置为初始值。
作为一种示例，终端设备在第n+10毫秒上检测到第一信号，则终端设备在第n+10毫秒上开启drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为2毫秒，那么终端设备在第n+11毫秒～第n+12毫秒上保持唤醒状态。
S207、网络设备发送第二DCI，终端设备接收该第二DCI。
由于网络设备在第n+10毫秒上发送第一信号，则网络设备在第n+11毫秒～第n+13毫秒之间会发送另一个DCI，在本申请实施例中，可以称为第二DCI。例如，网络设备在第n+12毫秒上发送第二DCI，则终端设备在第n+12毫秒上接收该第二DCI。
当终端设备开启drx-inactivity timerDL后，终端设备会在该定时器的运行期间内的每一毫秒上检测DCI，即分别在第n+11毫秒以及第n+12毫秒上检测DCI，并在第n+12毫秒上检测到该第二DCI。
S208、终端设备开启定时器以及重新检测第一信号。
当终端设备检测该第二DCI后，终端设备可以开启一个与drx-inactivity timerDL功能相同的定时器，该定时器可以是drx-inactivity timerDL，也可以是其他的定时器，在此不作限制。当该定时器为drx-inactivity timerDL时，可以理解为，重启S206中的drx-inactivity timerDL，也就是将drx-inactivity timerDL的计数值重置为初始值。为方便说明，在下文中以S208重启drx-inactivity timerDL为例。在drx-inactivity timerDL计时期间，终端设备处于唤醒状态，且在开启该drx-inactivity timerDL的时刻重新开始周期性检测第一信号。例如，终端设备在唤醒状态每隔4毫秒检测第一信号，当终端设备在第n+12毫秒上检测到该第二DCI，则终端设备可以从第n+12毫秒开始，开启一个初始值为12毫秒的drx-inactivity timerDL，且终端设备将在第n+12毫秒、第n+16毫秒、第n+20毫秒以及第n+24毫秒上分别检测第一信号，并根据第一信号的检测结果确定定时器的状态，也就是重复前述S202～S207的过程，在此不再赘述。
需要说明的是，当网络设备发送第二DCI后，网络设备也将在发送第二DCI的时刻重新开始周期性发送第一信号。
另外，需要说明的是，S207和S208为可选步骤，即不是必须要执行的，也就是说网络设备虽然在第n+10毫秒上发送第一信号，但是网络设备可以不在第n+11毫秒～第n+13毫秒上发送DCI，那么终端设备在第n+11毫秒～第n+13毫秒不会检测到第二DCI。
S209、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
若终端设备在第n+11毫秒～第n+13毫秒未检测到第二DCI，则当drx-inactivity timerDL超时，终端设备进入睡眠状态。或者，当终端设备检测到第二DCI，重新开启的drx-inactivity timerDL超时，则终端设备进入睡眠状态。需要说明的是，如果终端设备没有配置DRX短周期，则终端设备在drx-inactivity timerDL超时进入DRX长周期；如果终端设备配置了 DRX短周期，则终端设备在drx-inactivity timerDL超时先进入DRX长周期，再进入DRX短周期。
在S209之后，终端设备还可以执行其他步骤。作为一种示例，该其他步骤可以包括如下内容：
1、终端设备在S208中开启drx-inactivity timerDL时还开启了一个HARQ RTT timerDL，则终端设备在确定HARQ RTT timerDL超时，且相应HARQ进程缓存中的数据没有被成功解码，则终端设备为该HARQ进程启动drx-retransmission timerDL，从而使终端设备进入唤醒时间。
2、终端设备在drx-retransmission timerDL运行期间内，收到网络设备的发送的下行重传数据，则为该HARQ进程启动HARQ RTT timerDL，从而终端设备停止为该HARQ进程器启动的drx-retransmission timerDL，终端设备进入睡眠时间。当终端设备确定HARQ RTT timerDL超时，由于该HARQ RTT timerDL是网络设备重传数据触发的，所以当HARQ RTT timerDL超时后不会触发drx-retransmission timerDL，从而终端设备继续保持睡眠状态。终端设备在睡眠状态时，根据预设的条件确定是否启动on duration timer，该预设的条件与步骤S202相同，在此不再赘述，终端设备根据预设的条件启动on duration timer后，则进入唤醒时间。
3、终端设备在唤醒时间内收到网络设备发送的第三DCI，该第三DCI可以是下行/上行首传数据的PDCCH指示，从而，终端设备可以采用S203～S206确定是否启动drx-inactivity timerDL。以终端设备确定启动drx-inactivity timerDL为例，当终端设备确定on duration timer超时，由于drx-inactivity timerDL为运行状态，所以终端设备不进入睡眠时间，仍然保持对PDCCH的侦听。
4、终端设备收到DRX command MAC CE，终端设备进入睡眠时间。当然，若on duration timer和drx-inactivity timerDL处于运行状态，则终端设备停止on duration timer和drx-inactivity timerDL，然后进入睡眠时间。在这种情况下，如果终端设备没有配置DRX短周期，则终端设备直接进入DRX长周期；如果终端设备配置了DRX短周期，则终端设备先进入短周期。以终端设备进入DRX短周期为例。当终端设备进入DRX短周期，则启动drx-short cycle timer。在终端设备处于DRX短周期时，终端设备根据前述方法启动on duration timer、drx-inactivity timerDL、drx-retransmission timerDL、HARQ RTT timerDL中的一个或多个定时器。其中，DRX command MAC CE，用于指示终端设备立即进入睡眠时间的MAC信令。当终端设备接收到该命令后，则立刻停止on duration timer和drx-inactivity timer。
5、终端设备确定drx-short cycle timer超时后，终端设备则进入DRX长周期。并采用前述方式启动定时器，在此不再赘述。
需要说明的是，上述其他步骤不是本申请的主要发明点，因此，在图2中未示出。
在上述技术方案中，当终端设备确定该第一信号的检测结果指示终端设备不检测控制信道，则终端设备可以不开启用于唤醒终端设备的定时器，从而可以增加终端设备处于睡眠状态的时间，可以通过这种方式，在保证PDCCH检测性能的前提下，减少这部分能耗开销，可以提高终端设备的续航能力。
在图2所示的实施例中，介绍了网络设备通过是否发送第一信号来指示终端设备是否检测控制信道，且网络设备指示终端设备后续不检测控制信道的实施例进行说明。下面再 介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。
本申请实施例提供的一种信息检测方法的另一种实施例，请参考图4，为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S401、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
S402、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
S401～S402与S201～S202相同，且这两个步骤不响本发明实质，在此不再赘述。
S403、网络设备发送第一DCI及第一信号，终端设备检测第一DCI以及检测第一信号。
在本申请实施例中，对第一DCI和第一信号的说明，与S203中相同，在此不再赘述。终端设备在检测到第一DCI的时刻，会同时检测第一信号，如图3所示。
在本申请实施例中，以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。网络设备确定在发送第一DCI后还会继续发送DCI，则网络设备同步发送第一DCI和第一信号，例如，在第n+5毫秒上发送第一DCI和第一信号，从而终端设备在第n+5毫秒上接收该第一DCI以及检测到第一信号。
S404、终端设备根据第一信号的检测结果确定定时器的状态。
在本申请实施例中，对定时器的说明，与S204中相同，在此不再赘述。
具体来讲，当终端设备检测到第一DCI且检测到第一信号，则终端设备确定开启该定时器。在现有技术中，终端设备会在检测到第一DCI的毫秒上开启该定时器，并在该定时器的运行时长内的每毫秒上都会检测DCI。本实施例中，由于终端设备在这个毫秒上检测到该第一信号，也就是说，终端设备对第一信号的检测结果表示终端设备在该毫秒后检测该控制信道，也就是说，网络设备后续还会发送DCI，在这种情况下，终端设备确定开启该定时器，并将该定时器的计时重置为初始值，或者，终端设备确定保持该定时器为开启状态。
在下文中以该定时器为drx-inactivity timerDL为例。作为一种示例，终端设备在第n+5毫秒上检测到第一DCI，现有技术中，终端设备应在第n+5毫秒上开启drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为3毫秒，那么终端设备在第n+6毫秒、第n+7毫秒以及第n+8毫秒上保持唤醒状态。本实施例中，终端设备在第n+5毫秒上也对第一信号进行了检测，当检测到该第一信号时，终端设备确定在第n+5毫秒上开启drx-inactivity timerDL，并将drx-inactivity timerDL的计时重置为初始值3毫秒，这样，终端设备便在第n+6毫秒、第n+7毫秒以及第n+8毫秒上保持唤醒状态，且终端设备将在第n+6毫秒、第n+7毫秒以及第n+8毫秒上分别检测DCI。当未检测到第一信号时，终端设备不开启drx-inactivity timerDL。
这样，当终端设备确定该第一信号的检测结果指示终端设备检测控制信道，则终端设备可以开启用于唤醒终端设备的定时器，从而可以保证终端设备对PDCCH的检测性能。
S405、网络设备发送第二DCI，终端设备接收该第二DCI。
由于网络设备在第n+5毫秒上发送第一信号，则网络设备可能在第n+6毫秒～第n+8毫秒之间会发送另一个DCI，在本申请实施例中，可以称为第二DCI。例如，网络设备在第n+8毫秒上发送第二DCI，则终端设备在第n+8毫秒上接收该第二DCI。
S406、终端设备开启定时器以及重新检测第一信号。
S406与S208相同，在此不再赘述。
需要说明的是，当终端设备重新检测第一信号，例如，终端设备确定在第n+8毫秒上检测第一信号，且在该毫秒上未检测到第一信号，则终端设备确定关闭该drx-inactivity timerDL，然后在第n+12毫秒上检测第一信号，并根据第一信号的结果确定drx-inactivity timerDL的状态，即重复前述S403～S405的过程，在此不再赘述。
S407、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
S407与S209相同，在此不再赘述。
在S407之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图4中未示出。
在图4所示的实施例中，介绍了网络设备通过是否发送第一信号来指示终端设备是否检测控制信道，且网络设备指示终端设备后续需要检测控制信道的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。
本申请实施例提供的一种信息检测方法的另一种实施例，请参考图5，为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S501、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
S502、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
S501～S502与S201～S202相同，且这两个步骤不响本发明实质，在此不再赘述。
S503、网络设备发送第一DCI及第一信号，终端设备检测第一DCI以及检测第一信号。
在本申请实施例中，对第一DCI和第一信号的说明，与S203中相同，在此不再赘述。终端设备在检测到第一DCI的时刻，会同时检测第一信号，如图3所示。
在本申请实施例中，以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过该第一信号的内容来指示二项性为例。例如，当第一信号中携带的掩码为掩码1时，则用于指示终端设备检测DCI，当第一信号中携带的掩码为掩码2时，则用于指示终端设备不检测DCI。当网络设备确定在发送第一DCI后还会继续发送DCI，则网络设备确定在该第 一信号中携带掩码1，当网络设备确定在发送第一DCI后不会发送DCI，则确定在该第一信号中携带掩码2，然后，发送携带有掩码的第一信号。例如，在第n+5毫秒上发送第一DCI和第一信号，从而终端设备在第n+5毫秒上接收该第一DCI以及检测到第一信号。
S504、终端设备根据第一信号的检测结果确定定时器的状态。
在本申请实施例中，对定时器的说明，与S204中相同，在此不再赘述。
具体来讲，当终端设备检测到该第一信号，且根据该第一信号的内容确定该第一信号指示终端设备检测DCI时，则开启该定时器；或，当终端设备检测到该第一信号，且根据该第一信号的内容确定该第一信号指示终端设备不检测DCI时，确定该定时器的状态为关闭，或者说，关闭该定时器。例如，终端设备在接收该第一信号后，获取该第一信号中的掩码，当确定第一信号中携带的掩码为掩码1时，则开启该定时器，当第一信号中携带的掩码为掩码2时，则确定该定时器的状态为关闭。
终端设备确定开启该定时器或确定该定时器的状态为关闭的过程，与S404或S204中相应的内容相同，在此不再赘述。在图5中，以终端设备确定开启定时器为例。
S505、网络设备发送第二DCI，终端设备接收该第二DCI。
需要说明的是，当终端设备确定该定时器的状态为关闭，则终端设备可以参照图2中S205之后的步骤执行；当终端设备确定开启该定时器，则终端设备可以参考图4中S405之后的步骤执行。在图5中，以终端设备确定开启该定时器为例。
S506、终端设备开启定时器以及重新检测第一信号。
S507、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
S505～S507与S405～S407相同，在此不再赘述。
在S507之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，且在图5中未示出。
在图5所示的实施例中，介绍了网络设备通过第一信号的内容来指示终端设备是否检测控制信道的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。
本申请实施例还提供的一种信息检测方法，请参考图6A，其为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S601、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
S602、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
S601～S602与S201～S202相同，且这两个步骤不响本发明实质，在此不再赘述。
S603、网络设备发送第一DCI，终端设备检测第一DCI。
在本申请实施例中，对第一DCI的说明，与S203中相同，在此不再赘述。作为一种示例，网络设备在第n+5毫秒上发送第一DCI，则终端设备在第n+5毫秒上检测到该第一 DCI。
S604、终端设备开启定时器。
当终端设备检测到该第一DCI后，则在检测该第一DCI的毫秒开启该定时器。其中，对定时器的说明与S204中相同，在此不再赘述。
为方便描述，在下文中以该定时器为drx-inactivity timerDL为例。作为一种示例，当终端设备在第n+5毫秒上检测到该第一DCI，则终端设备在第n+5毫秒上开启drx-inactivity timerDL。假设drx-inactivity timerDL的初始值为3毫秒，终端设备会在第n+6毫秒、第n+7毫秒以及第n+8毫秒上保持唤醒状态，且终端设备将在第n+6毫秒、第n+7毫秒以及第n+8毫秒上分别检测DCI。
S605、终端设备检测第一信号，根据第一信号的检测结果确定drx-inactivity timerDL的状态。
在本申请实施例中，对第一信号的说明，与S203中相同，在此不再赘述。
需要说明的是，该第一信号的检测时刻与该第一DCI的检测时刻具有偏移量，该偏移量的值为正，请参考图6B，也就是说，终端设备在检测到第一DCI的第i毫秒加上偏移量j毫秒后的第(i+j)毫秒上检测该第一信号。该偏移量可以标记为offset，offset可以是个预定义的固定值，例如1毫秒，也可以是由网络设备配置的值，例如，网络设备在广播信令或者在专有RRC信令中配置该offset，在此不对该offset的设置方式进行限制。第一信号的时间长度可以是一个时间单元，也可以是多于一个时间单元。在第一信号的时间长度是一个时间单元的情况下，偏移量是第一DCI与第一信号之间的时间长度。在第一信号的时间长度是多余一个时间单元的情况下，偏移量可以是第一DCI与第一信号的起始时刻所间隔的时间长度，也可以是第一DCI与第一信号的截止时刻所间隔的时间长度，或者是第一DCI与第一信号的时间长度中的某个时刻所间隔的时间长度。
为方便说明，在下文中第一信号的时间长度为一个时间单元为例，以offset的值为1毫秒，且以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。作为一种示例，网络设备在第n+5毫秒上发送该第一DCI后，确定在第n+5毫秒之后不发送DCI，因此，网络设备不会发送第一信号，因此，终端设备在第n+6毫秒上未检测到该第一信号。
具体来讲，当终端设备未检测到该第一信号时，则确定关闭该drx-inactivity timerDL。需要说明的是，终端设备在检测到第一DCI的毫秒上开启drx-inactivity timerDL，从而终端设备会在drx-inactivity timerDL的计时时长内的每个毫秒上都检测DCI。然而，由于终端设备在检测到第一DCI的毫秒加上偏移量之后的毫秒上检测第一信号，且检测结果为未检测到该第一信号，则终端设备确定网络设备后续不会发送DCI，从而，终端设备在检测该第一信号的毫秒上关闭该drx-inactivity timerDL，也就是说，停止该drx-inactivity timerDL，并将关闭该drx-inactivity timerDL的计时重置为初始值。
作为一种示例，终端设备在第n+5毫秒上检测到第一DCI且开启drx-inactivity timerDL，假设drx-inactivity timer的初始值为3毫秒，从而终端设备本应在第n+6毫秒～第n+8毫秒上保持唤醒状态，且在第n+6毫秒～第n+8毫秒上的每个毫秒检测DCI。然而，由于终端设备在第n+6毫秒检测该第一信号且检测结果为未检测到该第一信号，则终端设备在第n+6毫秒上停止drx-inactivity timerDL。由于drx-inactivity timerDL在第n+6毫秒上的计时为2毫秒，因此，终端设备将drx-inactivity timerDL的计时重置为初始值，即重置为3毫 秒。需要说明的是，终端设备在第n+5毫秒上检测了第一DCI，在第n+6毫秒上至少检测了第一信号，也就是说，如果终端设备在每毫秒上都检测DCI，则终端设备在第n+6毫秒上既检测DCI又检测第一信号；若终端设备每隔预设的毫秒数检测DCI，例如，每隔一毫秒检测一次DCI，由于在第n+5毫秒上检测了第一DCI，因此，在第n+6毫秒上不检测DCI，在这种情况下，终端设备在第n+6毫秒上仅检测第一信号。
S606、网络设备发送第一信号，终端设备检测到第一信号。
S607、终端设备根据第一信号的检测结果确定drx-inactivity timerDL的状态。
S608、网络设备发送第二DCI，终端设备接收该第二DCI。
S609、终端设备开启定时器以及重新检测第一信号。
S610、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
S606～S610与S205～S209相同，在此不再赘述。
在S610之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图6A中未示出。
在图6A所示的实施例中，介绍了网络设备在不同的时刻检测第一DCI和第一信号，且网络设备通过是否发送第一信号来指示终端设备是否检测控制信道，并指示终端设备后续不检测控制信道的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。
本申请实施例还提供一种信息检测方法，请参考图7A，其为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。

S703、网络设备发送第一DCI，终端设备检测第一DCI。
S704、终端设备开启定时器。
S701～S704与S601～S604相同，在此不再赘述。
S705、网络设备发送第一信号，终端设备检测第一信号。
在本申请实施例中，对第一信号的说明，与S203中相同，在此不再赘述。该第一信号的检测时刻与该第一DCI的检测时刻具有偏移量，请参考图7B，也就是说drx-inactivity timerDL在检测第一信号之前已经开启了。对该偏移量的说明与S605中相同，在此不再赘述。
需要说明的是，网络设备发送第一信号的时刻与网络设备发送第一DCI的时刻也保持该偏移量，也就是说，网络设备在发送第一DCI的第i毫秒加上偏移量j毫秒后的第(i+j)毫秒上，发送该第一信号。
为方便说明，在下文中以offset的值为1毫秒，且以第一信号为通过以DCI的形式承 载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。作为一种示例，网络设备在第n+5毫秒上发送该第一DCI后，确定后续还会向终端设备发送DCI，因此，网络设备在第n+6毫秒上发送该第一信号，从而，终端设备在第n+6毫秒上检测到该第一信号。
S706、终端设备根据第一信号的检测结果确定drx-inactivity timerDL的状态。
具体来讲，当终端设备检测到该第一信号时，则确定重启或保持该drx-inactivity timerDL。
下面，对终端设备保持该drx-inactivity timerDL和重启drx-inactivity timerDL分别进行说明。
针对终端设备保持该drx-inactivity timerDL：
终端设备在检测到第一DCI的第i毫秒上开启drx-inactivity timerDL，从而终端设备会在drx-inactivity timerDL的计时时长内的每毫秒上都检测DCI。然而，由于终端设备在检测到第一DCI的第i毫秒加上偏移量之后的时刻上检测第一信号，且检测结果为检测到该第一信号，则终端设备确定网络设备后续还会发送DCI，从而，终端设备在检测该第一信号的毫秒上保持该drx-inactivity timerDL的开启状态，可以理解为，保持该drx-inactivity timerDL处于运行状态且不重置该drx-inactivity timerDL的计时。
作为一种示例，终端设备在第n+5毫秒上检测到第一DCI且开启drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为3毫秒，从而终端设备本应在第n+6毫秒～第n+8毫秒上保持唤醒状态，且在第n+6毫秒～第n+8毫秒上的每个毫秒检测DCI。然而，由于终端设备在第n+6毫秒检测该第一信号且检测结果为检测到该第一信号，则终端设备在第n+6毫秒上保持drx-inactivity timerDL的状态，此时，drx-inactivity timerDL在第n+6毫秒上的计时为2毫秒，drx-inactivity timerDL在当前计时值下继续计时，也就是说，该drx-inactivity timerDL将在第n+9毫秒上超时。
针对终端设备重启该drx-inactivity timerDL：
终端设备在检测到第一DCI的第i毫秒上开启drx-inactivity timerDL，从而终端设备会在drx-inactivity timerDL的计时时长内的每毫秒上都检测DCI。然而，由于终端设备在检测到第一DCI的第i毫秒加上偏移量之后的时刻上检测第一信号，且检测结果为检测到该第一信号，则终端设备确定网络设备后续还会发送DCI，从而，终端设备在检测该第一信号的毫秒上重启该drx-inactivity timerDL的开启状态，可以理解为，保持该drx-inactivity timerDL处于运行状态且将该drx-inactivity timerDL的计时重置为初始值。
作为一种示例，终端设备在毫秒n+5上检测到第一DCI且开启drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为3毫秒，从而终端设备本应在第n+6毫秒～第n+8毫秒上保持唤醒状态，且在第n+6毫秒～第n+8毫秒上的每毫秒上检测DCI。然而，由于终端设备在第n+6毫秒检测该第一信号且检测结果为检测到该第一信号，则终端设备在第n+6毫秒上保持drx-inactivity timerDL的状态，此时，drx-inactivity timerDL在第n+6毫秒上的计时为2毫秒，则终端设备将drx-inactivity timerDL在第n+6毫秒上的计时重置为3毫秒，从而该drx-inactivity timerDL在第n+10毫秒上超时。
需要说明的是，在图7A中以重启drx-inactivity timerDL为例。
S707、网络设备发送第二DCI，终端设备接收该第二DCI。
S708、终端设备开启定时器以及重新检测第一信号。
S709、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。

在图7A所示的实施例中，介绍了网络设备通过是否发送第一信号来指示终端设备是否检测控制信道，且网络设备指示终端设备后续需要检测控制信道的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。

S806、终端设备根据第一信号的检测结果确定定时器的状态。
在本申请实施例中，对定时器的说明，与S204中相同，在此不再赘述。
具体来讲，当终端设备检测到该第一信号，且根据该第一信号的内容确定该第一信号指示终端设备检测DCI时，则重启或保持该定时器；或，当终端设备检测到该第一信号，且根据该第一信号的内容确定该第一信号指示终端设备不检测DCI时，确定关闭该定时器。例如，终端设备在接收该第一信号后，获取该第一信号中的掩码，当确定第一信号中携带的掩码为掩码1时，则重启或保持该定时器，当第一信号中携带的掩码为掩码2时，则确定关闭该定时器。
终端设备关闭或重启或保持该定时器的过程，与S605或S706中相应的内容相同，在此不再赘述。
需要说明的是，当终端设备确定关闭该定时器，则终端设备可以参照图6A中S605之后的步骤执行；当终端设备确定重启或保持该定时器，则终端设备可以参考图7A中S706之后的步骤执行。在图8中，以终端设备确定重启该定时器为例。
S807、网络设备发送第二DCI，终端设备接收该第二DCI。
S808、终端设备开启定时器以及重新检测第一信号。
S809、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。

在S809之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行， 在此不再赘述，在图8中未示出。
在图8所示的实施例中，介绍了网络设备在检测到DCI的时刻开启定时器且在检测第一信号的时刻确定该定时器的状态的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。
本申请实施例提供另一种信息检测方法，请参考图9，其为该方法的示意图。

S904、终端设备检测第一信号，并根据第一信号的检测结果确定定时器的状态。
终端设备检测第一信号的过程与S605相同，在此不再赘述。终端设备在根据检测第一信号的检测结果，确定定时器的状态。具体来讲，当终端设备未检测到该第一信号时，则保持该定时器的关闭状态。为方便描述，在下文中以该定时器为drx-inactivity timerDL为例。
终端设备在检测到第一DCI的毫秒上未开启drx-inactivity timerDL，也就是说drx-inactivity timerDL为关闭状态。由于终端设备在检测到第一DCI的时刻加上偏移量之后时刻上检测第一信号，且检测结果为未检测到该第一信号，则终端设备确定网络设备后续不会发送DCI，因此，终端设备在检测该第一信号的时刻上保持该drx-inactivity timer的关闭状态，也就是说，不开启该drx-inactivity timerDL。
需要说明的是，终端设备周期性检测第一信号，且网络设备周期性确定是否发送第一信号，因此，当终端设备确定在某毫秒上的检测结果为未检测到该第一信号，则终端设备将在检测第一信号的周期时间内不检测DCI。例如，该周期可以是4毫秒，则网络设备每隔4毫秒确定是否发送第一信号，终端设备在唤醒状态每隔4毫秒检测第一信号。这样，网络设备在第n+6毫秒上未发送第一信号，表示网络设备在第n+6毫秒～第n+10毫秒上不会发送DCI。由于终端设备在第n+6毫秒上未检测到第一信号，因此，终端设备在第n+6毫秒～第n+10毫秒上不会检测到DCI。
S905、网络设备发送第一信号，终端设备检测到第一信号，并根据第一信号的检测结果确定drx-inactivity timerDL的状态。
具体来讲，当终端设备检测到该第一信号时，则开启该drx-inactivity timerDL。作为一种示例，以发送第一信号的周期为4毫秒，则网络设备在第n+10毫秒上确定在下一个周期内会发送DCI，则网络设备在第n+10毫秒上发送第一信号，终端设备在第n+10毫秒上 检测到第一信号。从而，终端设备开启该drx-inactivity timerDL，假设drx-inactivity timerDL的初始值为3毫秒，终端设备在第n+10毫秒～第n+12毫秒上保持唤醒状态，且在第n+10毫秒～第n+12毫秒上的每毫秒检测DCI。
S906、网络设备发送第二DCI，终端设备接收该第二DCI。
S907、终端设备开启定时器以及重新检测第一信号。
S908、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
S906～S908与S608～S610相同，在此不再赘述。
在S908之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图9中未示出。
在图9所示的实施例中，介绍了网络设备在检测到第一信号的时刻确定该定时器的状态的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定定时器的状态的其他情况。

S1004、网络设备发送第一信号，终端设备检测第一信号。
S1001～S1003与S801～S803相同，S1004与S805相同，在此不再赘述。
S1005、终端设备根据第一信号的检测结果确定定时器的状态。
在本申请实施例中，对定时器的说明，与S806中相同，在此不再赘述。
具体来讲，当终端设备检测到该第一信号，且该第一信号指示终端设备检测DCI，则开启该定时器；或，当该终端设备检测到该第一信号，且该第一信号指示终端设备不检测DCI时，保持该定时器的关闭状态。例如，终端设备在接收该第一信号后，获取该第一信号中的掩码，当确定第一信号中携带的掩码为掩码1时，则重启或保持该定时器，当第一信号中携带的掩码为掩码2时，则确定关闭该定时器。作为一种示例，请参考图10B，drx-inactivity timerDL在检测到第一DCI时不开启，在检测到第一信号且第一信号指示终端设备检测DCI的时候开启，也就是说，drx-inactivity timerDL在检测到第一DCI的时刻加上偏移量的时刻开启。
终端设备保持该定时器的关闭状态或开启该定时器的过程，与S904或S905中相应的内容相同，在此不再赘述。在图10A中以终端设备确定开启定时器为例。

针对第一信号的说明，与S203中相同，在此不再赘述。在本申请实施例中，以该第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。
需要说明的是，在本申请实施例中，第一信号用于指示在下一个检测第一信号的周期内，终端设备是否检测DCI，或者可以理解为，第一信号用于指示在下一个检测第一信号的周期内，网络设备是否发送DCI。
在本申请实施例中，终端设备根据网络设备配置的或者预先与网络设备约定的开始时刻及周期，周期性检测第一信号，请参考图11B，可以理解为，终端设备在检测到第一DCI之前检测第一信号，或者，第一信号的检测时刻与第一DCI的检测时刻具有偏移量，且该偏移量为负值。针对第一DCI的说明与S203相同，在此不再赘述。
作为一种示例，终端设备周期性检测第一信号的开始时刻为终端设备启动on duration timer后一毫秒上，且终端设备检测第一信号的周期为4毫秒，若终端设备在第n+4毫秒上启动on duration timer，则终端设备在第n+5毫秒上检测第一信号。网络设备确定在第一信号的第二个检测周期内不会发送DCI，则网络设备不会在第n+5毫秒上发送第一信号，从而终端设备不会在第n+5毫秒上检测到第一信号。
S1104、网络设备发送第一DCI，终端设备检测第一DCI以及开启定时器。
针对该定时器的说明，与S204中相同，在此不再赘述。为方便描述，在下文中以该定时器为drx-inactivity timerDL为例。

S1105、终端设备根据第一信号的检测结果确定drx-inactivity timerDL的状态。
当终端设备在接收第一DCI之前未检测到第一信号，则表示网络设备在下一个第一信号的检测周期内不会发送DCI，则终端设备关闭该drx-inactivity timerDL。作为一种示例，由于终端设备在第n+5毫秒上未检测到第一信号，则终端设备确定网络设备不会在第n+9毫秒～第n+13毫秒上发送DCI或终端设备确定在第n+9毫秒～第n+13毫秒上不检测DCI，则终端设备在下一个第一信号的检测周期开始的毫秒上关闭drx-inactivity timerDL，即，在第n+9毫秒上关闭drx-inactivity timerDL。需要说明的是，drx-inactivity timerDL本应第n+9毫秒上为开启状态，但由于终端设备确定在第n+9毫秒～第n+13毫秒上不检测DCI，因此，在第n+9毫秒上将该drx-inactivity timerDL关闭。
S1106、终端设备确定该on duration timer超时，则进入睡眠状态。
作为一种示例，若on duration timer的初始值为6毫秒，则终端设备在第n+4毫秒～第n+10毫秒上为唤醒状态。而drx-inactivity timerDL在第n+9毫秒上关闭，且终端设备根据第一信号的检测结果确定在第n+10毫秒上不检测DCI，则在第n+11毫秒上，on duration timer超时，终端设备进入睡眠状态。
在S1106之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图11A中未示出。

当终端设备在接收第一DCI之前检测到第一信号，则表示网络设备在下一个第一信号的检测周期内会发送DCI，则终端设备重启或保持该drx-inactivity timerDL。作为一种示例，由于终端设备在第n+5毫秒上检测到第一信号，则终端设备确定网络设备会在第n+9毫秒～第n+13毫秒上发送DCI或终端设备确定在第n+9毫秒～第n+13毫秒上检测DCI，则终端设备在下一个第一信号的检测周期开始的时刻上重启或开启该drx-inactivity timerDL的开启状态。需要说明的是，drx-inactivity timerDL本应第n+9毫秒上为开启状态，此时，该drx-inactivity timerDL的计时为0毫秒，由于终端设备确定在第n+9毫秒～第n+13毫秒上检测DCI，因此，在第n+9毫秒上重启该drx-inactivity timerDL，并将该drx-inactivity timerDL重置为初始值。或者，若该drx-inactivity timerDL在第n+9毫秒上为关闭状态，则终端设备开启该drx-inactivity timerDL。

S1206与S1006相同，在此不再赘述。
S1207、终端设备开启定时器。
该定时器可以为drx-inactivity timerDL，也可以是其他的定时器，在此不作限制。当该定时器为drx-inactivity timerDL时，可以理解为，重启S1204中的drx-inactivity timerDL，也就是将drx-inactivity timerDL的计数值重置为初始值。为方便说明，在下文中以S1207重启drx-inactivity timerDL为例。
S1208、终端设备根据第一信号的检测结果确定drx-inactivity timerDL的状态。
S1209、终端设备确定该drx-inactivity timerDL超时，则进入睡眠状态。
S1208与S1005相同，S1209与～S1008相同，在此不再赘述。
在S1208之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图12中未示出。
需要说明的是，网络设备还可以通过第一信号的内容指示终端设备是否在下一个检测第一信号的周期内检测DCI。当网络设备通过第一信号的内容指示终端设备是否在下一个检测第一信号的周期内检测DCI时，网络设备确定定时器的状态的过程与图11A～图12所示的实施例相似，在此不再赘述。
在图2～图12所示的实施例中，以定时器为drx-inactivity timerDL为例进行了说明。上述方法还可以应用于其他定时器，例如，用于指示在下行数据重传接收之前，终端设备检测控制信道的时间单元的个数的定时器，或者，可以理解为指示数据传输的控制信道之后终端设备检测控制信道的时间。作为一种示例，该定时器可以为drx-retransmission timerDL或者drx-retransmission timerUL。因此，下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定drx-retransmission timerDL的状态的过程。
本申请实施例还提供一种信息检测方法，请参考图13，其为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S1301、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
S1302、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
S1301～S1302与以上实施例相同，在此不再赘述。
S1303、网络设备发送第一DCI，终端设备接收该第一DCI。
针对第一DCI的说明，与S203中相同，在此不再赘述。
终端设备在唤醒时间内收到网络设备发送的第一DCI，则终端设备在接收该第一DCI的时刻启动drx-inactivity timer DL及HARQ RTT timerDL。
S1304、终端设备确定on duration timer超时，由于drx-inactivity timerDL为运行状态，所以终端设备不进入睡眠时间，仍然保持对PDCCH的侦听。
S1305、drx-inactivity timerDL超时，终端设备进入睡眠时间。
终端设备在drx-inactivity timerDL运行期间内未接收到其他DCI，因此，终端设备在drx-inactivity timerDL超时，进入睡眠时间。
S1306、终端设备确定下行数据传输失败，启动drx-retransmission timerDL。
终端设备确定HARQ RTT timerDL超时，且相应HARQ进程缓存中的数据没有被成功解码，则终端设备为该HARQ进程启动drx-retransmission timerDL，从而使终端设备进入唤醒时间。
S1307、终端设备检测第一信号，根据第一信号的检测结果确定drx-retransmission timerDL的状态。
若网络设备向终端设备传输数据，则网络设备会在终端设备的drx-retransmission timerDL运行期间发送用于指示重传数据的DCI，从而终端设备则在drx-retransmission timerDL运行期间接收该用于指示重传数据的DCI。该第一信号与图2所述实施例中描述相同，在此不再赘述。
在本申请实施例中，以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。
终端设备检测第一信号的起始时刻可以与终端设备开启drx-retransmission timer的时刻相同，例如，终端设备在时隙n+14上开启drx-retransmission timerDL，则终端设备在时隙n+14上检测该第一信号。或者，终端设备可以在与网络设备约定好的时刻或者网络设备配置的时刻检测该第一信号，例如，网络设备配置在开启drx-retransmission timerDL的时刻后一个时隙上发送第一信号，则终端设备在时隙n+15上检测该第一信号。同样地，网络设备也在终端设备检测第一信号的相同时刻确定是否发送该第一信号。若网络设备确定不发送重传数据，因此，网络设备不会在终端设备检测该第一信号的时刻发送该第一信号，即网络设备不发送用于指示重传数据的DCI，从而终端设备不会检测到该第一信号。
具体来讲，当终端设备未检测到该第一信号，则终端设备确定关闭drx-retransmission timerDL。现有技术中，终端设备应在drx-retransmission timerDL的运行时长内的每个时隙上都会检测是否有重传数据，然而在本实施例中，由于终端设备未检测到该第一信号，也 就是说，终端设备对第一信号的检测结果表示终端设备在该毫秒后不检测该控制信道，也就是说，网络设备后续不会发送用于指示重传数据的DCI，在这种情况下，终端设备便关闭drx-retransmission timerDL。
作为一种示例，假设drx-retransmission timerDL的初始值为5个时隙，那么终端设备本应在时隙n+14～时隙n+19上保持唤醒状态。由于终端设备在时隙n+15上未检测到第一信号，则终端设备在时隙n+15上关闭drx-retransmission timer，相当于drx-retransmission timer只运行了2个时隙，即时隙n+14和时隙n+15。
在图13中以终端设备在开启drx-retransmission timerDL的时刻后，检测第一信号为例。
S1308、终端设备进入睡眠状态。
在S1308之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图13中未示出。
这样，终端设备根据第一信号的检测结果在确定网络设备不会发送重传数据后，终端设备便可以提前关闭drx-retransmission timerDL，从而减少终端设备处于唤醒状态的时间，也即是增加终端设备处于睡眠状态的时间，可以通过这种方式，在保证PDCCH检测性能的前提下，减少这部分能耗开销，可以提高终端设备的续航能力。
在图13所示的实施例中，介绍了网络设备通过是否发送第一信号来指示终端设备是否检测控制信道，且网络设备指示终端设备后续不检测控制信道的实施例进行说明。下面再介绍另一个实施例，用于介绍终端设备根据第一信号确定drx-retransmission timerDL的状态的其他情况。
本申请实施例提供另一种信息检测方法，请参考图14，为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S1401、网络设备向终端设备发送DRX配置消息，终端设备接收该DRX配置信息，启动DRX模式。
S1402、终端设备启动on duration timer，从而进入唤醒状态，并检测控制信道。
S1403、网络设备发送第一DCI，终端设备接收该第一DCI。
S1404、终端设备确定on duration timer超时，由于drx-inactivity timerDL为运行状态，所以终端设备不进入睡眠时间，仍然保持对PDCCH的侦听。
S1405、drx-inactivity timerDL超时，终端设备进入睡眠时间。
S1406、终端设备确定下行数据传输失败，启动drx-retransmission timerDL。
S1401～S1406与S1301～S1306相同，在此不再赘述。
S1407、网络设备发送第一信号，终端设备检测第一信号。
该第一信号与图2所示的实施例中的第一信号相同，在此不再赘述。
在本申请实施例中，以第一信号为通过以DCI的形式承载在PDCCH上信号以及通过是否发送该第一信号来指示二项性为例。
终端设备检测第一信号的时刻及网络设备发送第一信号的时刻，与S1307中相同。在本申请实施例中，网络设备确定发送重传数据，因此，网络设备会在终端设备检测该第一信号的时刻发送该第一信号，即网络设备发送用于指示重传数据的DCI，从而终端设备检测到该第一信号。
S1408、终端设备根据第一信号的检测结果确定drx-retransmission timerDL的状态。
具体来讲，当终端设备检测到该第一信号，则终端设备确定重启或保持drx-retransmission timerDL。需要说明的是，终端设备本应在drx-retransmission timerDL的运行时长内的每个时隙上都会检测是否有重传数据，然而由于终端设备检测到该第一信号，可以理解为，终端设备对第一信号的检测结果表示终端设备在该时隙后检测该控制信道，也就是说，网络设备后续会发送用于指示重传数据的DCI，在这种情况下，终端设备保持drx-retransmission timerDL的开启状态。作为一种示例，假设drx-retransmission timerDL的初始值为5个时隙，那么终端设备本应在时隙n+14～时隙n+19上保持唤醒状态。终端设备在时隙n+15上检测到该第一信号，且drx-retransmission timerDL在时隙n+15上的计时为4个时隙，则终端设备不改变该drx-retransmission timerDL的计时值，继续检测重传数据，该drx-retransmission timerDL在时隙n+20上超时。
或者，当中终端设备检测到该第一信号后，终端设备可以在检测到该第一信号的时隙上重启drx-retransmission timerDL。作为一种示例，假设drx-retransmission timerDL的初始值为5个时隙，那么终端设备本应在时隙n+14～时隙n+19上保持唤醒状态。终端设备在时隙n+15上检测到该第一信号，且drx-retransmission timerDL在时隙n+15上的计时为4个时隙，则终端设备将该drx-retransmission timerDL的计时值重置为初始值，即，drx-retransmission timerDL在时隙n+15上的计时值变为5个时隙，然后继续检测重传数据，该drx-retransmission timerDL在时隙n+21上超时。
在图14中，以终端设备确定重启drx-retransmission timerDL为例。
S1409、网络设备发送第二DCI，终端设备接收该第二DCI。
第二DCI与图2所示的实施例中的第二DCI相同，在此不再赘述。
S1410、网络设备发送重传数据，终端设备发送重传数据。
S1411、终端设备进入睡眠状态。
在S1411之后，终端设备可以按照图2所示的实施例中S209之后的其他步骤进行执行，在此不再赘述，在图14中未示出。
需要说明的是，网络设备还可以通过第一信号的内容指示终端设备是否检测DCI。当网络设备通过第一信号的内容指示终端设备是否检测DCI时，网络设备确定定时器的状态的过程与图13～图14所示的实施例相似，在此不再赘述。
在图2～图14所示的实施例中，以终端设备根据第一信号的检测结果确定用于唤醒终端设备的定时器的状态的过程，例如，该定时器可以是drx-inactivity timerDL或者drx-inactivity timerUL或者drx-retransmission timerDL或者drx-retransmission timerUL等。本申请实施例中的信息检测方法也可以根据第一信号的检测结果确定是否开启一个用于使终端设备处于睡眠状态的定时器从而延长终端设备的睡眠时间，因此，下面再介绍另一个实施例，用于介绍终端设备根据第一信号的检测结果确定是否开启一个用于使终端设备处于睡眠状态的定时器的过程。
本申请实施例还提供一种信息检测方法，请参考图15，其为该方法的示意图。
在下文的介绍过程中，以该方法应用于图1所示的网络架构为例，也就是，下文中所述的网络设备可以是图1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1所示的网络架构中的终端设备。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，第一通信装置和第二通信装置分别与图2所示的实施例中的第一通信装置和第二通信装置相同，在此不再赘述。
为便于介绍，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。
S1501、终端设备检测第一信号。
在本申请实施例中，第一信号用于指示在HARQ RTT timerDL或HARQ RTT timerUL结束后的一段时间内所述终端设备是否检测控制信道。该段时间可以是该第一信号的检测周期。其中第一信号的具体形式以及内容与图2所示的实施例中的第一信号相同，在此不再赘述。在下文中，以HARQ RTT timerDL为例进行说明。
终端设备检测该第一信号的时刻可以为终端设备检测到下行重传数据的时刻或终端设备检测该第一信号的时刻与终端设备检测到下行重传数据的时刻具有偏移量。由于当终端设备检测到重传数据后，终端设备会进入休眠状态，因此，在本申请实施例中，该偏移量为负值，即终端设备在检测到重传数据之前检测该第一信号。该定时器为用于使终端设备处于睡眠状态的定时器，例如，可以为一个新的定时器，该定时器的初始值可以和HARQ RTT timerDL的初始值相同,也可以是网络侧为该定时器配置的初始值，或者是，协议预定义的该定时器的初始值。
S1502、终端设备根据该第一信号的检测结果确定定时器的状态。
S1502可以包括但不限于如下两种实现方式：
方式A，检测到第一信号和未检测到第一信号，用于指示终端设备是否检测控制信道，也就是说，当终端设备未检测到第一信号，则指示终端设备不检测控制信道，当终端设备检测到第一信号，则指示终端设备检测控制信道。这样，当终端设备未检测到该第一信号时，则开启该定时器；或，当所述终端设备检测到该第一信号时，确定该定时器状态为关闭。
具体来讲，当终端设备未检测到该第一信号，则网络设备在HARQ RTT timerDL结束后的一个检测第一信号的周期内不发送DCI，则终端设备在HARQ RTT timerDL结束时开启该定时器，例如，开启一个定时器，该定时器的初始值为检测第一信号的周期。从而，可以延长终端设备的睡眠时间。
方式B，通过第一信号中的内容指示终端设备是否检测控制信道。例如，当第一信号中的内容为掩码1时，确定该第一信号指示终端设备检测控制信道，当第一信号中的内容为掩码2时，确定该第一信号指示终端设备不检测控制信道。这样，当该终端设备检测到该第一信号，且该第一信号指示该终端设备检测控制信道时，则确定该定时器的状态为关闭，当终端设备检测到该第一信号，且该第一信号指示终端设备不检测控制信道时，则确定开启该定时器。
当终端设备检测到该第一信号，则网络设备在HARQ RTT timerDL结束后的一个检测第一信号的周期内会发送DCI，则终端设备在HARQ RTT timerDL接收后确定该定时器为关闭状态，或者，可以理解为不开启该定时器，从而可以保证终端设备接收DCI的性能。
另外，需要说明的是，上述图2～图12所示的实施例是可以与图13～图15所示的实施 例相互结合的，例如，在执行完成图2所示的实施例中的S209之后，可以采用图13所示的实施例S1306之后的步骤，或者图2所示的实施例中也可以同时开启HARQ RTT timerDL，也就是说图2所示的实施例也可以与图15所示的实施例结合。具体的结合方式在此不作限制。
上述本申请提供的实施例中，分别从网络设备、终端设备、以及网络设备和终端设备之间交互的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，网络设备和终端设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
