一种节能方法、装置及存储介质
本申请要求于2022年04月28日提交国家知识产权局、申请号为202210462537.4、申请名称为“一种节能方法、装置及存储介质”的中国专利申请的优先权，以及于2022年08月11日提交国家知识产权局、申请号为202210962007.6、申请名称为“一种节能方法、装置及存储介质”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，尤其涉及一种节能方法、装置及存储介质。
背景技术
近年来，随着通信技术的发展，扩展现实(extended reality，XR)技术也在不断进步和完善。目前，XR业务的数据帧的传输流程一般为服务器到固网/核心网，再到基站，由基站传输给终端设备。
理想的情况中，XR业务需要按照帧率，例如60帧每秒(frame per second，FPS)，周期性产生和传输数据帧，换言之，数据帧需要按照帧周期产生和传输。然而，出于服务器编码处理、固网/核心网传输等因素，XR业务的数据帧到达基站时，不一定严格遵守周期性。这也导致基站将XR业务的数据帧传输给终端设备时，不一定严格按照帧周期进行传输，终端设备可能无法严格按照帧周期接收数据帧。
另一方面，出于节能的考虑，长期演进(long term evolution，LTE)或者新空口(new radio，NR)系统中引入了使终端设备不需要持续监听物理下行控制信道(physical downlink control channel，PDCCH)的技术，例如PDCCH跳过(PDCCH skipping)技术和非连续接收(discontinuous reception，DRX)技术，这些技术可以使终端设备在一定时间内不监听PDCCH。但是，目前这些技术都不能满足终端设备接收XR业务的数据帧所需要的监听PDCCH的时间。
综上，如何控制终端设备合理地跳过PDCCH的监听，使终端设备在监听PDCCH的时间与XR业务的数据帧的传输时间匹配的基础上获得节能的效果，是目前亟待解决的问题。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
1、XR业务：
目前，XR业务的数据帧的传输流程一般为服务器到固网/核心网，再到基站，由基站传输给终端设备。通常情况下，若XR业务为视频业务，XR业务的数据帧也可以称为画面帧或者视频帧。
理想的情况中，XR业务需要按照帧率，周期性产生和传输数据帧，换言之，数据帧需要按照帧周期产生和传输。其中，这里的帧周期也可以称为XR业务的周期，或者数据的周期。因为目前XR业务的帧率一般为60帧每秒(frame per second，FPS)，90FPS、120FPS或者180FPS等，所以相对应的XR业务的周期一般为非整数。例如，若帧率为60FPS，则对应的XR业务的周期为16.67ms，每隔16.67ms服务器产生和传输一个数据帧。
然而，由于服务器编码处理、固网/核心网传输等因素，XR业务的数据帧到达基站时，不一定严格遵守周期性。如图1所示，帧率为60FPS的视频，理想情况下，基站处每隔16.67毫秒到达一个画面帧。然而实际上每个画面帧到达基站的延迟不等，帧间隔不再是严格的16.67毫秒，这种情况可以称为帧的到达时刻存在抖动(jitter)。示例性的，如图1所示，第二帧相比理想情况延后到达5毫秒,即jitter＝5ms，第四帧相比理想情况提前到达了3毫秒，即jitter＝-3ms。
可以理解的是，XR业务的数据帧不一定严格遵守周期性到达基站，也导致了基站将XR业务的数据帧传输给终端设备时，不一定严格按照帧周期进行传输，终端设备可能无法严格按照帧周期接收数据帧。
2、DRX技术：
DRX技术是为了降低终端设备功耗而引进的技术。DRX技术的基本机制是给终端设备配置DRX周期(DRX cycle)，DRX周期包括激活时间段和非激活时间段，终端设备在激活时间段内正常监听PDCCH，在非激活时间段进入休眠状态，不监听PDCCH以减少功耗。
DRX周期内的激活时间段也可以被称为持续时间(on Duration/on Duration Timer)，如图2所示，终端设备可以在on Duration期间监听PDCCH，on Duration超时后，终端设备进入非激活时间段，停止监听PDCCH，直至进入下一个DRX周期的on Duration再监听PDCCH。
从图2可以看出，相邻两次on Duration的间隔时长即为DRX周期的时长。时长较长的DRX周期，终端设备休眠的时间较久，有益于降低终端设备的功耗，时长较短的DRX周期，有益于终端设备更快地响应来接收数据。因此，为了满足不同的需求，终端设备可以被配置两种DRX周期：短DRX周期(shortDRX-Cycle)和长DRX周期(longDRX-Cycle)，终端设备在任一时刻使用其中一种DRX周期。
需要说明的是，DRX周期一般是由基站配置给终端设备的，且DRX周期一般为整数值。
3、搜索空间集合(search space set，SS set)
为了降低终端设备频繁监听PDCCH带来的功耗，基站会为终端设备定义一个或多个搜索空间集合，搜索空间集合指的是一组PDCCH监听时机(monitor occasion，MO)的集合， 终端设备在基站配置好的搜索空间集合内的MO监听PDCCH，而无需在搜索空间集合没有包括的MO上进行PDCCH的监听，从而可以节省功耗。
终端设备可以根据搜索空间包含的如下信息，进行PDCCH的监听：monitoringSlotPeriodicityAndOffset、duration、monitoringSymbolsWithinSlot。
其中，monitoringSlotPeriodicityAndOffset定义该搜索空间的周期和在该周期内的进行PDCCH监听的起始偏移时隙(offset)。duration定义在一个搜索空间周期内，该搜索空间对应的要求监听的连续时隙(slot)的数量，例如duration为2，表示在一个搜索空间周期内，要求持续监听两个连续的时隙。monitoringSymbolsWithinSlot可以定义在前述duration个时隙的一个时隙内，在哪个符号(symbol)开始监听PDCCH。
本申请实施例中，这种通过搜索空间集合监听PDCCH的方法也可以被称为PDCCH监测(PDCCH monitoring)，搜索空间周期也可以称为PDCCH monitoring的周期，或者称为监测周期。目前，PDCCH monitoring的周期一般为整数个时隙。
示例性的，如图3所示，假设监测周期包括k个时隙，起始偏移时隙为O个时隙，duration为L，monitoringSymbolsWithinSlot指示在duration个时隙内，从符号1开始监听PDCCH，在一个监测周期内，起始偏移时隙过后，终端设备持续监听L个时隙，并在时隙内按照monitoringSymbolsWithinSlot指示的符号监听PDCCH。其余时间终端设备可以不进行监听，直至下一个监测周期。此外，图3中阴影部分代表的监听PDCCH对应的符号数量，以及监听PDCCH的频域范围由搜索空间关联的控制信道资源集合(coreset)定义。
进一步地，搜索空间集合可以属于不同的搜索空间集合组(search space set group，SSSG)。SSSG是由基站配置给终端设备的，例如SSSG包括的搜索空间等信息。基站还会为终端设备配置与SSSG对应的PDCCH监听相关配置，终端设备可以根据与SSSG对应的PDCCH监听相关配置，在SSSG内的搜索空间上监听PDCCH。其中，基站可以通过无线资源控制(radio resource control,RRC)信令为终端设备配置SSSG。
基于基站为终端设备配置的SSSG对应的PDCCH监听相关配置，可以将SSSG分为稀疏SSSG(sparse SSSG)与密集SSSG(dense SSSG)。稀疏SSSG相较于密集SSSG，监听PDCCH的时间较为稀疏。示例性的，假设SSSG 0配置为每间隔三个时隙来监听PDCCH，SSSG 1配置为每一个时隙都需要监听PDCCH，可以将SSSG0称为稀疏SSSG，将SSSG1称为密集SSSG。
对于稀疏SSSG和密集SSSG的配置，以及稀疏SSSG和密集SSSG分别对应的PDCCH监听相关配置，可以是基于基站的实现确定的。
示例性的，为了便于理解，以下结合图4进行说明。假设基站为终端设备配置SSSG0和SSSG1，其中，SSSG 0配置为每间隔一个时隙来监听PDCCH，SSSG 1配置为每一个时隙都需要监听PDCCH，SSSG 0和SSSG1中的搜索空间集合的监测周期被配置为2个时隙。如图4所示，终端设备在SSSG0内的搜索空间集合上监听PDCCH时，第一次的监测周期包括时隙0和时隙1，第二次的监测周期包括时隙3和时隙4，其他监测周期以此类推。终端设备在SSSG1内的搜索空间集合上监听PDCCH时，第一次的监测周期包括时隙0和时隙1，第二次的监测周期包括时隙2和时隙3，其他监测周期以此类推。终端设备在监测周期内监听PDCCH的具体实现可以参考上文介绍。从图4可以看出，在SSSG0内监听PDCCH的时间较稀疏，在SSSG1内监听PDCCH的时间较密集，因此，SSSG0可以称为稀疏SSSG，SSSG1可以称为密集SSSG。
可以基于下行控制信息(downlink control information,DCI)指示搜索空间集合组的切换(SSSG switch)。例如，在DCI中增加PDCCH监测适应指示(PDCCH monitoring adaptation indication)域(包含1个或者2个比特)，通过PDCCH monitoring adaptation indication域指示终端设备是否执行搜索空间集合组切换。在PDCCH monitoring adaptation indication域包括1比特，且基站为终端设备配置两个SSSG的情况下，PDCCH monitoring adaptation indication域指示的用户设备行为(user equipmentbehaviors，UE behaviors)可以如下表1所示：
表1
在PDCCH monitoring adaptation indication域包括2比特，且基站为终端设备配置三个SSSG的情况下，PDCCH monitoring adaptation indication域指示的用户设备行为可以如下表2所示：
表2
除了可以通过DCI指示SSSG切换之外，还可以基于定时器进行SSSG的切换。例如，基站可以在RRC信令中配置搜索空间切换定时器(search space switch timer)，当该定时器超时后，用户从SSSG X(X＝1，2)切换到SSSG 0。其中，搜索空间切换定时器的用途可以理解为在该定时器超时后，终端设备从一个SSSG切换至另一个SSSG，搜索空间切换定时器也可以称为SSSG切换定时器。
4、PDCCH跳过(skipping)
为了使终端设备可以跳过一些额外的不需要监听的PDCCH以进一步降低终端设备的功耗，终端设备可以支持PDCCH skipping。例如可以在DCI中包含PDCCH监测适应指示(PDCCH monitoring adaptation indication)域(包含1个或者2个比特)，通过PDCCH monitoring adaptation indication域来指示终端设备需要跳过PDCCH监听的时长。
PDCCH monitoring adaptation indication域指示的用户设备行为可以如下表3所示：
表3
以上表3为例进行解释，示例性的，若PDCCH monitoring adaptation indication域为两个比特，且比特值为“01”，则终端设备在接收到DCI后，在持续时间集合中第一个值对应的时长内跳过PDCCH的监听。其中，持续时间集合中的值，或者说，终端设备可以跳过PDCCH监听的候选时长(候选PDCCH skipping的时长)，是通过RRC信令中的PDCCH跳过时长列表-r17(PDCCH Skipping DurationList-r17)字段来配置的。如表3所示，PDCCH Skipping DurationList-r17字段最多可以配置三个候选PDCCH skipping的时长。
需要说明的是，目前PDCCH Skipping DurationList-r17字段可以配置的候选PDCCH skipping的时长是以时隙为粒度的，换言之，目前PDCCH Skipping DurationList-r17字段可以配置的候选PDCCH skipping的时长一般为整数个时隙。
综上，PDCCH skipping技术中，终端设备在接收到DCI后，根据DCI中PDCCH monitoring adaptation indication域确定指示的是PDCCH Skipping DurationList-r17字段配置的哪个PDCCH skipping的时长值，从而在对应的时长内跳过PDCCH的监听。
需要注意的是，在PDCCH monitoring adaptation indication域包括2比特，且基站为终端设备配置了两个SSSG以及两个候选PDCCH skipping的时长的情况下，PDCCH monitoring adaptation indication域指示的用户设备行为可以如下表4所示：
表4
在上文中，介绍了XR业务，以及出于节能的考虑，终端设备不需要持续监听PDCCH的技术：DRX、PDCCH monitoring和PDCCH skipping。但是，这些技术都不能满足终端设备接收XR业务的数据帧所需要的监听PDCCH的时间。以下进行具体介绍：
1、DRX技术使终端设备周期性地监听PDCCH，但是DRX周期一般为整数值，和XR业务的非整数的周期值不匹配。示例性的，假设XR业务的帧率为60FPS，则对应的周期为16.67ms，则最接近帧周期的DRX周期为16ms，如图5所示，XR业务的到达时间与DRX周期内的onDuration时间逐渐错开。与此同时，XR业务的数据帧的到达时间可能还存在jitter，为了使得数据帧到达基站后能够及时调度，需要将on Duration的长度设置为涵盖整个jitter的范围，例如jitter的可能数值为-4ms≤jitter≤4ms，相较于理想到达时间，数据帧最早可提前到达4ms，最晚可延迟到达4ms，则on Duration需要设置为8ms。而对于60FPS的XR业务来说，最接近数据的周期的DRX周期为16ms，则终端设备需要在接近一半的时间内监听PDCCH,导致终端设备的功耗过高。
2、与DRX技术不能满足终端设备接收XR业务的数据帧所需要的PDCCH监听时机的原因相似，以时隙为时间单位，PDCCH monitoring的周期一般为整数个时隙，XR业务的周期一般为非整数个时隙，PDCCH monitoring的周期值与XR业务的周期值不匹配。且因为XR业务的数据帧的到达时间可能存在jitter，导致终端设备需要在很长时间内监听PDCCH。
3、PDCCH skipping的时长最多支持3个以时隙为单位的数值，而对于XR业务而言，由于jitter、帧大小可变以及调度策略等原因，XR业务实际所需跳过PDCCH监听的时长的变化范围较广，最多3个数值的PDCCH skipping时长不能满足XR业务的实际需求。以下以一个具体的示例进行解释，如图6所示，假设终端设备配置为持续监听PDCCH，XR业务的帧率为60FPS，jitter的范围为-4ms≤jitter≤4ms，终端设备可以跳过PDCCH监听的时长的范围如图6所示。其中，可能的最长范围的情况为：数据帧比理想到达时间早到了4ms,该数据帧经过了3个slots完成传输，若以毫秒为粒度进行计算，此时终端设备需要跳过PDCCH监听的时长为16.67-1.5＝15.17ms,换算成时隙单位则为30slots。而可能的最短范围的情况为：数据帧比理想到达时间晚到了4ms,由于帧大小的原因或者重传一共经过了7个slots完成传输,此时终端设备需要跳过PDCCH监听时间的长度为8.67-3.5＝3.17ms,换算成时隙单位则为6slots。可以看出，终端设备需要跳过PDCCH监听的时长范围为6slots～30slots,以时隙为单位共有25个长度范围，而RRC信令最多能配置3个以时隙为单位的的候选PDCCH skipping时长，无法满足XR业务所需要的跳过PDCCH监听的时长的变化情况。
综上，如何控制终端设备跳过PDCCH的监听，使终端设备在监听PDCCH的时间与XR业务的数据帧的传输时间匹配的基础上获得节能的效果，是目前亟待解决的问题。基于此，本申请实施例提供一种节能方法，可以合理控制终端设备跳过PDCCH的监听的时间，使终端设备监听PDCCH的时间与XR业务的数据帧的传输时间相匹配。

下面将结合图1至图9，以图7所示的网络设备70与任一终端设备80进行交互为例，对本申请实施例提供的节能方法进行展开说明。
需要说明的是，本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，本申请实施例对此不作具体限定。
如图10所示，为本申请实施例提供的一种节能方法。图10中以网络设备和终端设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图10中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图10中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。该节能方法包括S1001和S1002：
S1001、网络设备向终端设备发送第一指示信息，相对应的，终端设备接收来自网络设备的第一指示信息。
S1002、终端设备根据第一指示信息在第一时长内跳过PDCCH的监听；其中，第一时长与数据的周期或者帧率相关。可选地，PDCCH承载用于调度该数据的信息。
S1001中，网络设备给终端设备发送的第一指示信息用于指示终端设备跳过PDCCH的监听。
需要说明的是，本申请实施例中，跳过PDCCH的监听，也可以称为跳过监听PDCCH，不监听PDCCH，暂停监听PDCCH，避免监听PDCCH或者停止监听PDCCH。
需要说明的是，本申请实施例中，监听PDCCH可以涉及中射频处理和基带处理，跳过中射频处理或基带处理中的至少一项处理就可以理解为跳过PDCCH的监听。示例性的，跳过中射频处理可以包括关闭接收信号的射频硬件。跳过基带处理可以包括跳过以下至少一项：
获得PDCCH资源位置。
根据无线网络临时标识(radio network temporary identifier，RNTI)进行循环冗余码校验(cyclic redundancy check，CRC)。
在CRC成功的情况下，解码PDCCH上的相应信息；在CRC失败的情况下，继续在下一个PDCCH资源位置上进行PDCCH的监听。
本申请实施例中，网络设备可以根据向终端设备传输数据的传输情况，判断是否向终端设备发送第一指示信息。
一种可能的实现方式中，网络设备可以在确定传输给终端设备的数据已经传输完毕时，或者，在确定传输给终端设备的数据来不及在规定时间内传输完毕时，或者，在确定传输给终端设备的数据已经传输完毕后经过一段时间后，向终端设备发送第一指示信息，指示终端设备跳过PDCCH的监听。其中，网络设备确定数据的传输情况的具体实现与该数据对应的业务类型相关。例如，若网络设备向终端设备传输XR业务的数据帧，网络设备可以在确定当前传输的某一数据帧的数据已经全部完成传输时，或者在确定当前传输的某一数据帧无法在给定时间内，例如无法在包时延预算(packet delay buget，PDB)内传输完毕时，或者在确定当前传输的某一数据帧的数据已经全部完成传输时再经过一段时间，向终端设备发送第一指示信息。
可选的，本申请实施例中，在终端设备支持一种业务，网络设备向终端设备传输该业务的数据的情况下，网络设备可以根据该业务的数据的传输情况，判断是否发送第一指示信息。在终端设备支持多种业务，网络设备向终端设备传输多种业务分别对应的数据的情况下，网络设备可以根据其中一种业务的数据的传输情况，判断是否需要发送第一指示信息。以下为了简要介绍，可以将用于网络设备判断是否发送第一指示信息的数据对应的业务，称为第一业务。
示例性的，终端设备支持XR业务和增强移动宽带(enhanced mobile broadband，eMBB)业务，网络设备可以根据XR业务的数据帧的传输情况，判断是否需要向终端设备发送第一指示信息。该场景下，XR业务可以称为第一业务。
可选的，本申请实施例中，第一指示信息可以携带在DCI中。
对于S1002，终端设备接收到第一指示信息后，根据第一指示信息的指示，确定与数据的周期或者帧率相关的第一时长，在第一时长内跳过PDCCH的监听。在第一时长结束后，终端设备可以继续监听PDCCH。其中，在数据以帧的形式进行传输时，数据的帧率指单位时间内传输的帧的数量，数据的周期指相邻两帧到达网络设备的间隔时长，数据的周期的值为数据的帧率的值的倒数。
本申请实施例中，终端设备可以从成功解码第一指示信息开始，跳过PDCCH的监听。或者，终端设备可以在成功解码第一指示信息一段时间后，开始跳过监听PDCCH。其中，终端设备成功解码第一指示信息的时间，与终端跳过监听PDCCH的开始时间之间的时长，可以取决于终端设备的能力。
基于本申请实施例提供的节能方法，终端设备可以根据第一指示信息的指示，在与数据的周期或者帧率相关的第一时长内，跳过PDCCH的监听。不同于现有的跳过PDCCH监听的时长与数据的周期或者帧率无关的方案，本申请实施例提供的节能方法可以控制终端设备跳过PDCCH监听的时长与数据的周期或者帧率相关，因此可以在数据周期性传输的场景中，使终端设备监听PDCCH的时间与数据的传输时间相匹配。
可选的，针对上文介绍的，因为XR业务的周期为非整数值，以整数值的周期监听PDCCH的方法不能满足终端设备接收XR业务的数据帧所需要的监听PDCCH的时间的问题，本申请实施例的技术方案可以应用于终端设备接收XR业务的数据帧的场景，相对应的，与第一时长相关的数据的周期可以为XR业务的周期，例如可以为z毫秒，其中，z为非整数。示例性的，数据的周期可以为33.33ms、16.67ms或者8.33ms等。与第一时长相关的数据的帧率可以为XR业务的帧率，例如数据的帧率可以为30FPS、60FPS、120FPS等。当然，本申请实施例的技术方案在数据的周期为整数值的情况下，依然可以应用。
以下展开介绍本申请实施例中第一时长的确定。
本申请实施例中，为了使得终端设备监听PDCCH的时间与数据的传输时间匹配，第一时长需要与数据的周期或者帧率相关。示例性的，数据的周期可以为XR业务的帧周期，数据的帧率可以为XR业务的帧率。
本申请实施例中，第一时长与数据的周期或者帧率相关，因此终端设备要确定第一时长需要获取数据的周期或者帧率，或者需要获取与数据的周期或帧率相关的参数。以下介绍几种示例性的方式。
一种可能的实现方式中，数据的周期或者帧率、或者与数据的周期或帧率相关的参数可以是由网络设备配置给终端设备的。例如，网络设备在发送给终端设备的信令中，携带数据的周期或者帧率、或者携带与数据的周期或者帧率相关的参数，例如，可以在RRC信令中，携带数据帧率的相关参数用来配置30FPS,60FPS，90FPS，120FPS等数据帧率,或者携带数据周期的相关参数用来配置1/30秒,1/60秒,1/90秒,1/120秒等数据周期，或者，终端设备可以从自身的应用层获取数据的周期或者帧率。或者，终端设备可以根据业务来包特征(业务数据包到达的特征)进行感知，获得数据的周期或者帧率。当然，终端设备还可以通过其他方式获取数据的周期或者帧率，或者获取与数据的周期或帧率相关的参数，本申请实施例并不限制终端设备获取数据的周期或者帧率，或者获取与数据的周期或帧率相关的参数的具体实现方式。
可选的，本申请实施例中，为了终端设备侧和网络设备侧对第一时长具有统一的理解，网络设备也可以确定第一时长。为了确定第一时长，网络设备也需要获取数据的周期或者帧率，或者需要获知与数据的周期或帧率相关的参数。一种可能的方式中，网络设备可以接收来自终端设备的用于指示数据的周期或者帧率的信息。例如，终端设备可以通过用户辅助信息(user assistant information，UAI)将数据的周期或者帧率、或者与数据的周期或帧率相关的参数发送给网络设备。或者，网络设备可以根据业务来包特征进行感知，获得数据的周期或者帧率。或者，还可以由核心网设备告知网络设备数据的周期或者帧率，或者与数据的周期或帧率相关的参数。当然，网络设备还可以通过其他方式获取数据的周期或者帧率的数值，本申请实施例并不限制网络设备获取数据的周期或者帧率的数值的具体实现方式。
以上介绍了终端设备如何获取数据的周期或者帧率。终端设备在接收到第一指示信息后，可以根据数据的周期或者帧率，以及预定义的算法、模型或者计算规则，确定第一时长。其中，根据预定义的算法、模型或者计算规则确定的第一时长，可以控制终端设备在跳过PDCCH的监听后开始监听PDCCH的时间，与数据的传输时间(或者说网络设备发送数据的时间)相匹配。
需要说明的是，本申请实施例中，两者匹配可以理解为两者相等或者两者之间的差距在一定阈值之内。其中，一定阈值可以是预定义的，也可以根据实际需求设置。例如，如果传输的数据为XR业务的数据帧，则一定阈值可以为XR业务的jitter的最大绝对值。换言之，终端设备开始监听PDCCH的时间与数据的传输时间匹配可以理解为，网络设备传输的数据，终端设备可以在开始监听PDCCH时接收到，或者可以在开始监听PDCCH后的一定时长内接收到，因此终端设备不会浪费功耗。
可选的，若网络设备也需要确定第一时长，则网络设备可以根据相同的算法、模型或者计算规则，从而根据数据的周期或者帧率，确定与终端设备确定的第一时长相同的时长。
可选的，本申请实施例中，第一时长还可以与以下至少一项相关：
接收到第一指示信息的时间，或者，由网络设备配置的第一参考时间。
可选的，本申请实施例中，接收到第一指示信息的时间可以是网络设备通过空口资源发送第一指示信息的时间。或者，接收到第一指示信息的时间可以是网络设备通过空口资源发送第一指示信息后经过一定偏移值的时间，该偏移值是由网络设备配置或者通过预定义的方式得到的。例如，网络设备可以通过RRC信令中的PDSCH-TimeDomainResourceAllocation信元配置的k0值，来配置发送第一指示信息的时间与第一指示信息开始生效的时间之间的偏移时长。或者，接收到第一指示信息的时间可以是第一指示信息的空口资源所在的时域位置。或者，接收到第一指示信息的时间可以是第一指示信息的空口资源所在的时域位置经过一定偏移值的时间，该偏移值是由网络设备配置或者通过预定义的方式得到的。或者，接收到第一指示信息的时间可以是第一指示信息开始生效的时间。
第一参考时间，是本申请实施例中的一个用于确定第一时长的参考时间。
可选的，第一参考时间可以用于表征第一业务的开始时间，也可以理解为第一业务的数据开始传输的时间。例如，若第一业务为XR业务，则第一参考时间可以为XR业务的第一个数据帧到达网络设备的时间。
或者，第一参考时间可以为第一业务的数据预估开始传输的时间(也可以理解为理想情况下第一业务的数据帧到达网络设备的时间)累加一定偏移后的时间。可选的，若第一业务为XR业务，该偏移的值可以与jitter相关。例如，若第一业务为XR业务，且第一业务的jitter的范围为-4ms≤jitter≤4ms，则第一参考时间可以为第一业务的第一个数据帧预估的开始传输时间之前4毫秒、3毫秒、2毫秒或者1毫秒的时间，或者第一参考时间也可以为第一业务的第一个数据帧预估的开始传输时间之后4毫秒、3毫秒、2毫秒或者1毫秒的时间。
或者，第一参考时间可以为第一业务的某一次数据的开始传输的时间，其中，某一次在第一次之后。例如，若第一业务为XR业务，则第一参考时间可以为第一业务的第一个数据帧之后的数据帧中，某一个数据帧到达网络设备的时间。
或者，第一参考时间可以为第一业务的某一次数据的预估开始传输的时间累加一定偏移后的时间，其中，某一次在第一次之后。可选的，若第一业务为XR业务，该偏移的值可以与jitter相关。例如，若第一业务为XR业务，则第一参考时间可以为第一业务的第一个数据帧之后的数据帧中，某一个数据帧预估的开始传输时间加上jitter的可能取值之后的时间。
需要说明的是，上述列举的四种可能的第一参考时间，是本申请实施例提供的示例性的第一参考时间，本申请实施例并不限制设置第一参考时间的具体实现方式。
本申请实施例中，第一参考时间由网络设备配置。网络设备可以将承载第一参考时间相关参数的信息发送给终端设备。其中，可选的，网络设备可以将承载第一参考时间的信息发送给终端设备。或者，在第一参考时间为第一业务的数据预估开始传输的时间累加一定偏移后的时间的情况下，网络设备可以将承载第一业务的数据预估开始传输的时间和偏移值的相关参数的信息发送给终端设备，由终端设备根据第一业务的数据预估开始传输的时间和偏移值，确定第一参考时间。示例性的，网络设备可以通过RRC信令为终端设备配置第一参考时间。
终端设备在接收到第一指示信息后，可以根据数据的周期或者帧率，以及接收到第一指示信息的时间和第一参考时间中的至少一项，通过预定义的算法、模型或者计算规则，确定第一时长。

示例四：该示例中，如果timeReferenceSFN<＝SFNskipping indication，，第一时长满足如下关系：
Duration＝(M×1024+timeReferenceSFN)×numberOfSlotsPerFrame+timeDomainOffset
+floor[N×100/ArriveRate×numberOfSlotsPerFrame]–((M×1024+SFNskipping indication)×numberOfSlotsPerFrame+slotskipping indication)；           公式(7)
如果timeReferenceSFN>SFNskipping indication,第一时长满足如下关系：
Duration＝((M+1)×1024+timeReferenceSFN)×numberOfSlotsPerFrame+
timeDomainOffset+floor[N×100/ArriveRate×numberOfSlotsPerFrame]–((M×1024+SFNskipping indication)×numberOfSlotsPerFrame+slotskipping indication)；       公式(8)
上述公式(7)或者公式(8)中，Duration表示第一时长；floor表示向下取整；timeReferenceSFN表示第一参考时间的系统帧号，timeDomainOffset表示第一参考时间相对于timeReferenceSFN的时隙偏移值，例如，假设第一参考时间所在的时隙为第一参考时间所在的系统帧中的第2个时隙，则timeDomainOffset＝2；SFNskipping indication表示接收到第一指示信息的时间的系统帧号；slotskipping indication表示接收到第一指示信息的时间相对于SFNskipping indication的时隙偏移值，例如，假设接收到第一指示信息的时间所在的时隙为接收到第一指示信息的时间所在的系统帧中的第3个时隙，则timeDomainOffset＝3；numberOfSlotsPerFrame表示一个系统帧内的时隙数量；ArriveRate表示数据的帧率，即每秒内传输的数据帧的数量；N是递增的整数，表示接收到第一指示信息时，数据的第N个周期，例如，假设接收到第一指示信息时，业务的数据帧为第4个周期的数据帧，则N＝4；M是递增的整数，表示系统帧号的反转(wraparound)次数,M满足如下关系：
M＝floor(N×100/ArriveRate)modulo(1024)；        公式
(9)
上述公式(9)中，floor表示向下取整；modulo表示取模；N、ArriveRate的含义与上述公式(7)或者公式(8)中的N、ArriveRate的含义相同。
需要说明的是，上述公式(7)或者公式(8)中，100/ArriveRate×numberOfSlotsPerFrame也可以等价替换为1/ArriveRate×numberOfSlotsPerSecond；其中，numberOfSlotsPerSecond表示每秒内的时隙数量。
示例五：该示例中，第一时长可以是，接收到第一指示信息的时间所在的时隙的结束时刻，与满足下述关系并且离接收到第一指示信息的时间最近的时隙的起始时刻之间的间隔时长：
[(SFN×numberOfSlotsPerFrame)+slot number in the frame]＝(timeReferenceSFN×
numberOfSlotsPerFrame+timeDomainOffset+M)modulo(1024×numberOfSlotsPerFrame)     公式(10)
上述公式(10)中，SFN是时隙的系统帧号；slot number in the frame表示时隙在所在的系统帧内的索引，例如，假设时隙在所在的系统帧内是第2个时隙，则slot number in the frame＝2；modulo表示取模；numberOfSlotsPerFrame、timeReferenceSFN、timeDomainOffset含义与上述公式(7)或者公式(8)中的numberOfSlotsPerFrame、timeReferenceSFN、timeDomainOffset的含义相同；M是递增的整数，且M满足如下关系：
Int[M×ArriveRate/1000]+1＝Int[(M+1)×ArriveRate/1000]；        公式(11)
上述公式(11)中，Int表示向上取整或者向下取整；ArriveRate表示数据的帧率，即每秒内传输的数据帧的数量。
为了便于理解，以下结合附图，对示例二中如何确定第一时长进行说明。如图11所示，以数据为XR业务的数据帧，c表示第一参考时间的时隙索引为例，可以看出，第一参考时间的配置可以考虑数据帧的jitter，第一参考时间较第一个数据帧的理想到达时间有一定偏移。y表示数据帧的周期(数据周期)，s表示时隙长度。d1表示终端设备第一次接收到第一指示信息的时间的时隙索引。其中，用于确定一个数据周期包括的时隙的数量。第二个数据帧与第一个数据帧之间间隔一个数据周期，因此，终端设备可以根据c，以及推测出第二个数据帧的可能到达时间的时隙索引：终端设备从接收到第一指示信息后，开始跳过PDCCH的监听，因此终端设备可以根据第一次接收到第一指示信息的时间的时隙索引d1，以及第二个数据帧的可能到达时间的时隙索引： 确定出终端设备第一次接收到第一指示信息后，需要跳过PDCCH监听的第一时长：X1。d2表示终端设备第二次接收到第一指示信息的时间的时隙索引。第三个数据帧与第一个数据帧之间间隔两个数据周期，同理可得，用于确定两个数据周期包括的时隙的数量，终端设备可以根据c，以及推测出第三个数据帧的可能到达时间的时隙索引：进一步地，终端设备可以根据第二次接收到第一指示信息的时间的时隙索引d2，以及第三个数据帧的可能到达时间的时隙索引：确定出终端设备第二次接收到第一指示信息后，需要跳过PDCCH监听的第一时长：X2。
需要说明的是，上述公式(1)-公式(8)以及公式(10)为本申请实施例提供的九种示例性的用于确定第一时长的计算规则，本申请实施例并不限制用于确定第一时长的算法、模型或者计算规则的形式。可以理解的是，将上述公式(1)-公式(8)以及公式(10)中参数的时间粒度适应性替换为其余时间粒度，例如符号或子时隙等，依然可以应用于确定其他种类时间粒度下的第一时长。
从上文对上述示例一、示例二、示例三和示例四的说明可以看出，在第一时长与数据的周期或者帧率，以及接收到第一指示信息的时间和第一参考时间相关的情况下，因为相对时间位置关系的改变，第一时长可以理解为可变时长。
可选的，考虑到多种业务混合的场景，本申请实施例中，网络设备还可以向终端设备发送第二指示信息，第二指示信息用于指示终端设备在第二时长内跳过PDCCH的监听。其中，第二时长是由网络设备配置的固定值，因此第二时长可以理解为固定时长。网络设备可以根据多种业务的数据传输情况，向终端设备发送第一指示信息或者第二指示信息。
可选的，本申请实施例提供的节能方法还可以包括S1003：
S1003、网络设备向终端设备发送第一配置信息，相对应的，终端设备接收来自网络设备的第一配置信息。其中，前述的第一指示信息指示根据第一配置信息在第一时长内跳过PDCCH的监听。
在本申请实施例提供的节能方法包括S1003的情况下，S1002可以为：网络设备向终端设备发送第一指示信息后，终端设备可以在第一指示信息的指示下，根据第一配置信息确定第一时长，在第一时长内跳过PDCCH的监听。在第一时长结束后，终端设备可以继续监听PDCCH。
可选的，本申请实施例中，第一配置信息可以为指示PDCCH skipping的候选时长的参数，该参数表征需要以与数据的周期或者帧率相关的第一时长跳过PDCCH的监听。其中，网络设备可以仅配置第一配置信息来指示配置的PDCCH skipping的候选时长。或者，考虑到多种业务混合的场景，除配置第一配置信息来针对第一业务外，网络设备还可以配置一个或多个固定值作为候选的PDCCH skipping的时长，从而可以根据不同的业务数据的传输情况，指示终端设备在第一时长内，或者在配置的固定值的时长内，跳过PDCCH的监听。
示例性的，第一配置信息可以携带在RRC信令中。例如，可以通过RRC信令的PDCCHSkipDurationList-R17字段配置第一配置信息，又例如，也可以通过RRC信令中一个新定义的字段来配置第一配置信息。
以下结合示例，对本申请实施例中第一配置信息的多种可能的实现进行展开介绍。
一种可能的实现方式中，第一配置信息与数据的周期或者帧率相对应，也可以称为第一配置信息与第一业务的周期或者帧率相对应。该实现方式中，终端设备在确定第一时长时，可以根据第一配置信息获知数据的周期或者帧率。
可选的，该实现方式中，第一配置信息还可以与子载波间隔(sub-carrier space，SCS)相对应。
示例性的，在第一配置信息为PDCCHSkipDurationList-R17字段中的参数的情况下，若数据为XR业务的数据帧，其帧率为30FPS、60FPS、120FPS或者180FPS，第一配置信息可以为对应帧率的tailored for periodic traffic of 30FPS，tailored for periodic traffic of 60FPS，tailored for periodic traffic of 120FPS或者tailored for periodic traffic of 180FPS。
假设第一配置信息与SCS对应，数据为XR业务的数据帧，其帧率为30FPS，SCS可以为15kHz、30kHz、60kHz或者120kHz，PDCCHSkipDurationList-R17携带的三个指示PDCCH skipping的候选时长的参数分别为1、100和第一配置信息，则PDCCHSkipDurationList-R17字段可以为：
{1,100，tailored for periodic traffic of 30FPS}slots for 15kHz SCS；该PDCCHSkipDurationList-R17字段与15kHz的SCS对应。
或者，{1,100，tailored for periodic traffic of 30FPS}slots for 30kHz SCS；该PDCCHSkipDurationList-R17字段与30kHz的SCS对应。
或者，{1,100，tailored for periodic traffic of 30FPS}slots for 60kHz SCS；该PDCCHSkipDurationList-R17字段与60kHz的SCS对应。
或者，{1,100，tailored for periodic traffic of 30FPS}slots for 120kHz SCS；该PDCCHSkipDurationList-R17字段与120kHz的SCS对应。
可以理解的是，若第一配置信息与数据的周期对应，上述示例中与帧率，例如30FPS对应的第一配置信息，也可以将帧率替换为对应的周期，例如第一配置信息可以为tailored for periodic traffic of 1/30s。
另一种可能的实现方式中，不同周期或者帧率的数据对应同一第一配置信息。
可选的，该实现方式中，第一配置信息还可以与SCS相对应。
示例性的，在第一配置信息为PDCCHSkipDurationList-R17字段中的参数的情况下，若数据为XR业务的数据帧，第一配置信息可以为tailored for periodic traffic。
假设第一配置信息与SCS对应，数据为XR业务的数据帧，SCS可以为15kHz、30kHz、60kHz SCS或者120kHz，PDCCHSkipDurationList-R17携带的三个指示PDCCH skipping的候选时长的参数分别为1、100和第一配置信息，则PDCCHSkipDurationList-R17字段可以为：
{1,100，tailored for periodic traffic}slots for 15kHz SCS；该PDCCHSkipDurationList-R17字段与15kHz的SCS对应。
或者，{1,100，tailored for periodic traffic}slots for 30kHz SCS；该PDCCHSkipDurationList-R17字段与30kHz的SCS对应。
或者，{1,100，tailored for periodic traffic}slots for 60kHz SCS；该PDCCHSkipDurationList-R17字段与60kHz的SCS对应。
或者，{1,100，tailored for periodic traffic}slots for 120kHz SCS；该PDCCHSkipDurationList-R17字段与120kHz的SCS对应。
又示例性的，在第一配置信息为RRC信令中一个新定义的字段的参数的情况下，若该新定义的字段可以对不同的SCS生效，该新定义的字段可以为PDCCHSkipDuration for periodic traffic-ENABLE:True/False。其中，该字段配置为True时，可以用于表示第一配置信息。该字段可以对多个SCS生效。或者，若该新定义的字段与SCS对应，SCS可以为15kHz、30kHz、60kHz SCS或者120kHz，则该新定义的字段可以为：
{PDCCHSkipDuration for periodic traffic-ENABLE:True/False}for 15kHz SCS；该字段与15kHz的SCS对应。
或者，{PDCCHSkipDuration for periodic traffic-ENABLE:True/False}for 30kHz SCS；该字段与30kHz的SCS对应。
或者，{PDCCHSkipDuration for periodic traffic-ENABLE:True/False}for 15kHz  SCS；该字段与60kHz的SCS对应。
或者，{PDCCHSkipDuration for periodic traffic-ENABLE:True/False}for 120kHz SCS；该字段与120kHz的SCS对应。
需要说明的是，本文在对出现的字段，或者字段中的参数的名称，例如tailored for periodic traffic of 30FPS，PDCCHSkipDuration for periodic traffic-ENABLE:True/False以及后文出现的名称，进行介绍时，是本申请实施例提供的示例性的可能名称，本申请实施例并不限制它们的具体名称。
以上介绍了第一配置信息的具体实现。以下对本申请实施例中，终端设备如何根据第一指示信息的指示，根据第一配置信息在第一时长内跳过PDCCH的监听进行展开介绍。
可选的，终端设备可以根据第一指示信息以及预定义的映射关系，确定与第一指示信息对应的信息为第一配置信息，从而根据第一配置信息确定自身需要确定第一时长，并在第一时长内跳过PDCCH的监听。
一种可能的实现方式中，第一指示信息可以为PDCCH monitoring adaptation indication域，终端设备可以根据PDCCH monitoring adaptation indication域的比特值，以及预定义的映射关系，确定与PDCCH monitoring adaptation indication域的比特值对应的信息，若与PDCCH monitoring adaptation indication域的比特值对应的信息为第一配置信息，则终端设备根据数据的周期或者帧率，确定第一时长，并在第一时长内跳过PDCCH的监听。
以下结合具体示例进行解释，假设第一指示信息为PDCCH monitoring adaptation indication域，PDCCHSkipDurationList-R17字段为{1,100，tailored for periodic traffic of 30FPS}slots for 15kHz SCS；其中，tailored for periodic traffic of 30FPS为第一配置信息，且第一配置信息是PDCCHSkipDurationList-R17字段配置的三个指示PDCCH skipping的候选时长的参数中的第三个参数。第一指示信息和指示的用户设备行为可以如下表5所示：
表5
如上表5所示，当PDCCH monitoring adaptation indication域的比特值为“11”时，终端设备可以根据表5所示的对应关系，确定以tailored for periodic traffic of 30FPS对应的时长，即第一时长跳过PDCCH的监听。终端设备确定需要在第一时长内跳过PDCCH的监听后，根据数据的帧率30FPS，确定第一时长。同理，当PDCCH monitoring adaptation indication域的比特值为“0”或者“00”时，终端设备可以根据表5所示的对应关系，确定无需跳过监听PDCCH，可以继续监听PDCCH。当PDCCH monitoring adaptation indication域的比特值为“1”或者“01”时，终端设备可以根据表5所示的对应关系，确定需要跳过PDCCH监听的时长为1slot。当PDCCH monitoring adaptation indication域的比特值为“10”时，终端设备可以根据表5所示的对应关系，确定需要跳过PDCCH监听的时长为10slot。
以下对本申请提供的节能方法中的一个示例性的具体实施例进行介绍。假设数据为XR业务的数据帧，图12中以网络设备和终端设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图12中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图12中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。该实施例包括：S1201-S1204：
S1201、网络设备在向终端设备发送的RRC信令中，携带用于配置PDCCH skipping的候选时长的第一配置信息，其中，第一配置信息指示跳过与XR业务的周期相匹配的动态时长(第一时长)。
S1201的具体实现可以参考上文对S1003的介绍，在此不再赘述。
S1202、网络设备向终端设备传输XR业务的数据帧。
S1203、网络设备向终端设备发送DCI，其中携带第一指示信息，第一指示信息指示终端设备根据第一配置信息跳过PDCCH的监听。
S1203的具体实现可以参考上文对S1001和S1003的介绍，在此不再赘述。
S1204、终端设备根据第一指示信息，确定本次需要跳过的PDCCH skipping的时长为第一配置信息指示的候选时长，即第一时长。终端设备根据预定义的计算规则以及XR业务的周期计算第一时长，并在第一时长内跳过PDCCH的监听。
S1204的具体实现可以参考上文对S1001和S1003的介绍，在此不再赘述。
可选的，在第一指示信息指示根据第一配置信息在第一时长内跳过PDCCH的监听的情况下，第一指示信息还可以指示进行SSSG切换。换言之，如果终端设备在第一指示信息的指示下，确定需要根据第一配置信息确定第一时长，那么终端设备还需要在第一指示信息的指示下，进行SSSG切换。在该场景中，网络设备为终端设备配置多个SSSG。
一种可能的实现方式中，终端设备可以根据第一指示信息以及预定义的映射关系，确定与第一指示信息对应的信息为第一配置信息，从而根据第一配置信息确定自身需要确定第一时长并在第一时长内跳过PDCCH的监听，以及根据第一配置信息确定进行SSSG切换。
另一种可能的实现方式中，终端设备可以根据第一指示信息以及预定义的映射关系，确定与第一指示信息对应的信息为第一配置信息，若终端设备确定与第一指示信息对应的信息为第一配置信息，则终端设备可以根据与第一配置信息不同的另一配置信息，确定需要进行SSSG切换。其中，用于终端设备确定需要进行SSSG切换的配置信息，可以为新定义的信息，也可以复用现有的信息，本申请实施例对此不做限制。
以下结合具体示例，对第一指示信息指示根据第一配置信息在第一时长内跳过PDCCH的监听以及进行SSSG切换进行解释。
假设网络设备为终端设备配置了SSSG0和SSSG1，第一指示信息为PDCCH monitoring  adaptation indication域，PDCCHSkipDurationList-R17字段为{1,100，tailored for periodic traffic of 30FPS}slots for 15kHz SCS；其中，tailored for periodic traffic of 30FPS为第一配置信息，且第一配置信息是PDCCHSkipDurationList-R17字段配置的三个指示PDCCH skipping的候选时长的参数中的第三个参数。第一指示信息和指示的用户设备行为可以如下表6所示：
表6
如上表6所示，假设终端设备当前在SSSG1中的搜索空间监听PDCCH，当终端设备接收到DCI，且DCI中的PDCCH monitoring adaptation indication域的比特值为“11”时，终端设备可以根据表6所示的对应关系，确定需要以tailored for periodic traffic of 30FPS对应的时长，即第一时长跳过PDCCH的监听。并且，终端设备根据表6所示的对应关系，确定需要切换到SSSG0，在SSSG0中的搜索空间监听PDCCH。同理，当PDCCH monitoring adaptation indication域的比特值为“0”、“00”、“1”、“01”或者“10”时，终端设备无需切换SSSG，可以继续在当前的搜索空间监听PDCCH。
以下介绍两种终端设备根据第一指示信息的指示进行SSSG切换的方式。
方式(a)、终端设备在第一时长内跳过PDCCH的监听后，切换到第一指示信息指示的SSSG。可以理解的是，该实现方式也可以基于搜索空间切换定时器实现，具体地，终端设备在接收到第一指示信息后，将搜索空间切换定时器设置为第一时长，在该定时器超时后，终端设备切换到第一指示信息指示的SSSG。
方式(b)、终端设备在接收到第一指示信息后，切换到第一指示信息指示的SSSG，同时在第一时长内跳过PDCCH的监听。
可选的，第一指示信息指示切换的SSSG，可以是稀疏SSSG。
进一步地，终端设备可以根据第一指示信息的指示，从密集SSSG切换到稀疏SSSG。换言之，终端设备在接收到第一指示信息之前，可以在密集SSSG中的搜索空间上监听PDCCH。
以下对本申请提供的节能方法中的一个示例性的具体实施例进行介绍。假设数据为XR业务的数据帧，图13中以网络设备和终端设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图13中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图13中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。该实施例包括：S1301-S1306：
S1301、网络设备在向终端设备发送的RRC信令中，携带用于配置密集SSSG和稀疏SSSG的配置信息以及第一配置信息，其中，第一配置信息指示跳过与XR业务的周期相匹配的动态时长(第一时长)，以及指示进行SSSG切换。
S1301中，稀疏SSSG为SSSG0，密集SSSG为SSSG1。
S1302、终端设备在稀疏SSSG中的搜索空间上监听PDCCH。其中，终端设备先在SSSG0中的搜索空间上监听PDCCH可以是协议默认的，也可以是网络设备配置的。
S1303、网络设备向终端设备传输XR业务的数据帧，其中，网络设备在调度XR业务的第一个传输块(transport block，TB)时，下发DCI指示终端设备切换到密集SSSG，即指示终端设备切换到SSSG1。
S1304、终端设备接收到S1203中网络设备下发的DCI后，切换到SSSG1，在SSSG1中的搜索空间监听PDCCH。
S1305、网络设备向终端设备发送DCI，其中携带第一指示信息，第一指示信息指示终端设备根据第一配置信息跳过PDCCH的监听以及进行SSSG切换。
S1305中，网络设备可以根据向终端设备传输XR业务的数据帧的传输情况，判断是否向终端设备发送第一指示信息，具体可以参考上文对S1001的介绍，在此不再赘述。
S1306、终端设备根据第一指示信息，确定本次需要跳过的PDCCH skipping的时长为第一配置信息指示的候选时长，即第一时长，进一步地，终端设备还确定需要切换到稀疏SSSG。
S1306中，终端设备在第一指示信息的指示下，一方面根据预定义的计算规则以及XR业务的周期计算第一时长，并在第一时长内跳过PDCCH的监听。另一方面，终端设备进行SSSG切换，切换到SSSG0。
S1306的具体实现可以参考上文对S1003的介绍，在此不再赘述。
上文从终端设备与网络设备之间交互的角度，对S1301-S1306进行说明，为了便于理解，以下结合图14，对S1301-S1306中，终端设备如何根据网络设备下发的DCI进行SSSG切换进行说明。
如图14所示，终端设备首先在稀疏SSSG(SSSG0)中的搜索空间监听PDCCH。网络设备在调度XR业务数据帧的第一个TB时，向终端设备发送第一个DCI，指示终端设备切换到密集SSSG(SSSG1)。终端设备根据该DCI的指示，切换至SSSG1，继续在SSSG1中的搜索空间监听PDCCH。网络设备根据XR业务数据帧的传输情况，向终端设备发送第二个DCI，该DCI指示终端设备在第一时长内跳过PDCCH的监听并进行SSSG切换。
终端设备接收到第二个DCI后，计算出第一时长。终端设备在第一时长内跳过PDCCH的监听，并切换到稀疏SSSG0。其中，若终端设备按照上文介绍的根据第一指示信息的指示进行SSSG切换的方式中的方式(a)，在跳过PDCCH的监听的结束时刻，切换到SSSG0，其切换到SSSG0的时间点如图14中的黑色箭头所示。若终端设备按照上文介绍的根据第一指示信息的指示进行SSSG切换的方式中的方式(b)，在接收到第二个DCI后，切换到SSSG 0，同时在第一时长内跳过PDCCH的监听，其切换至SSSG0的时间点如图14中的白色箭头所示。
本申请实施例还提供另一种节能方法，如图15所示，为本申请实施例提供的一种节能方法。图15中以网络设备和终端设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图15中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图15中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。该节能方法包括S1501和S1502：
S1501、网络设备向终端设备发送第三指示信息，相对应的，终端设备接收来自网络设备的第三指示信息。
S1502、终端设备跳过监听PDCCH，直至下一PDCCH监听周期开始；其中，下一PDCCH监听周期的开始时间与终端设备接收数据的时间相匹配。
需要说明的是，本申请实施例中，终端设备配置有PDCCH监听周期，可以按照PDCCH监听周期，周期性地监听PDCCH。且终端设备的PDCCH监听周期的开始时间与终端设备接收网络传输的数据的时间相匹配。换言之，网络设备向终端设备传输数据的周期，与终端设备的PDCCH监听周期相匹配。
S1501中，第三指示信息用于指示终端设备跳过监听PDCCH，直至下一PDCCH监听周期开始。因为网络设备向终端设备传输数据的周期，与终端设备的PDCCH监听周期相匹配，所以终端设备可以在下一PDCCH监听周期及时接收到网络设备下一次传输的数据，且不会有数据在终端设备跳过PDCCH监听的时间内进行传输，可以避免多余的PDCCH监听时间，从而节省功耗。
示例性的，本申请实施例中，PDCCH监听周期可以为DRX技术中，激活时间段或者on Duration的周期。或者，PDCCH监听周期还可以为PDCCH monitoring技术中的PDCCH monitoring周期，或者也可以称为Duration的周期。
本申请实施例中，网络设备可以根据向终端设备传输数据的传输情况，判断是否向终端设备发送第三指示信息。网络设备判断是否向终端设备发送第三消息的具体实现可以参考上文对S1001的介绍，在此不再赘述。
可选的，本申请实施例中，第三指示信息可以携带在DCI中。
对于S1502，终端设备接收到第三指示信息后，根据第三指示信息的指示，跳过监听PDCCH，直至下一PDCCH监听周期开始。下一PDCCH监听周期开始后，终端设备可以继续监听PDCCH。
可选的，终端设备接收到第三指示信息时，若终端设备当前还处于PDCCH监听周期，终端设备可以根据第三指示信息，跳过当前PDCCH监听周期中对PDCCH的监听，直至下一PDCCH监听周期开始。当然，若终端设备接收到第三指示信息时，终端设备当前没有在监听PDCCH，终端设备依然可以根据第三指示信息的指示，持续跳过PDCCH的监听，直至下一PDCCH监听周期开始。
基于本申请实施例提供的节能方法，终端设备可以根据第三指示信息的指示，跳过监听PDCCH，直至下一PDCCH监听周期开始。从而在数据的传输周期，与终端设备的PDCCH监听周期相匹配的场景中，尽可能地避免多余的PDCCH监听时间，从而节省功耗。
可选的，本申请实施例中，数据的周期可以为非整数值，例如可以为z毫秒，其中，z为非整数。当然，本申请实施例的技术方案在数据的周期为整数值的情况下，依然可以应用。
本申请实施例中，终端设备根据第三指示信息跳过PDCCH的监听时，需要确定下一次PDCCH监听周期的开始时间。因此，终端设备需要获取PDCCH监听周期。一种可能的实现方式中，PDCCH监听周期、或者与PDCCH监听周期相关的参数可以是由网络设备配置给终端设备的。例如，网络设备在发送给终端设备的RRC信令中，携带PDCCH监听周期、或者与PDCCH监听周期相关的参数。当然，终端设备还可以通过其他方式获取PDCCH监听周期，本申请实施例并不限制终端设备获取PDCCH监听周期的具体实现方式。
可选的，本申请实施例提供的节能方法还可以包括S1503：
S1503、网络设备向终端设备发送第二配置信息，相对应的，终端设备接收来自网络设备的第二配置信息。其中，前述的第三指示信息指示根据第二配置信息，跳过监听PDCCH，直至下一PDCCH监听周期开始。
在本申请实施例提供的节能方法包括S1503的情况下，S1502可以为：网络设备向终端设备发送第三指示信息后，终端设备可以在第三指示信息的指示下，根据第二配置信息确定下一次PDCCH监听周期的开始时间，并停止监听PDCCH，直至下一PDCCH监听周期开始。在下一PDCCH监听周期开始后，终端设备继续监听PDCCH。
可选的，本申请实施例中，第二配置信息可以为配置的，指示PDCCH skipping的候选时长的参数，该参数表征跳过PDCCH的监听直至下一PDCCH监听周期开始。其中，网络设备可以仅配置第二配置信息来指示配置的PDCCH skipping的候选时长。或者，考虑到多种业务混合的场景，除配置第二配置信息外，网络设备还可以配置一个或多个固定值作为候选的PDCCH skipping的时长，从而可以根据不同的业务数据的传输情况，指示终端设备根据第二配置信息跳过PDCCH的监听直至下一PDCCH监听周期开始，或者指示终端设备在配置的固定值的时长内，跳过PDCCH的监听。
示例性的，第二配置信息可以携带在RRC信令中。例如，可以通过RRC信令的PDCCHSkipDurationList-R17字段配置第二配置信息，示例性的，在第二配置信息为PDCCHSkipDurationList-R17字段中的参数的情况下，第二配置信息可以为skip to next Monitoring Occasion。又例如，可以通过RRC信令中一个新定义的字段来配置第二配置信息。
可选的，本申请实施例中，第二配置信息可以与SCS相对应。
示例性的，假设第二配置信息与SCS对应，SCS可以为15kHz、30kHz、60kHz或者120kHz，PDCCHSkipDurationList-R17携带的三个PDCCH skipping的值分别为1、100和第二配置信息，则PDCCHSkipDurationList-R17字段可以为：
{1,100，skip to next Monitoring Occasion}slots for 15kHz SCS；该PDCCHSkipDurationList-R17字段与15kHz的SCS对应。
或者，{1,100，skip to next Monitoring Occasion}slots for 30kHz SCS；该PDCCHSkipDurationList-R17字段与30kHz的SCS对应。
或者，{1,100，skip to next Monitoring Occasion}slots for 60kHz SCS；该PDCCHSkipDurationList-R17字段与60kHz的SCS对应。
或者，{1,100，skip to next Monitoring Occasion}slots for 120kHz SCS；该PDCCHSkipDurationList-R17字段与120kHz的SCS对应。
需要说明的是，上文在对第二配置信息的可能实现进行介绍时，出现的字段，或者字段中的参数的名称，例如skip to next Monitoring Occasion，是本申请实施例提供的示例性的可能名称，本申请实施例并不限制第二配置信息的具体名称。
以上介绍了第二配置信息。以下对本申请实施例中，终端设备如何根据第三指示信息的指示，根据第二配置信息跳过PDCCH的监听，直至下一PDCCH监听周期开始进行展开介绍。
可选的，终端设备可以根据第三指示信息以及预定义的映射关系，确定与第三指示信息对应的信息为第二配置信息，从而根据第二配置信息确定需要跳过PDCCH的监听，直至下一PDCCH监听周期开始。
一种可能的实现方式中，第三指示信息可以为PDCCH monitoring adaptation indication域，终端设备可以根据PDCCH monitoring adaptation indication域的比特值，以及预定义的映射关系，确定与PDCCH monitoring adaptation indication域的比特值对应的信息，若与PDCCH monitoring adaptation indication域的比特值对应的信息为第二配置信息，则终端设备确定下一PDCCH监听周期的开始时间，并跳过PDCCH的监听直至下一PDCCH监听周期的开始时间。
以下结合具体示例进行解释，假设第三指示信息为PDCCH monitoring adaptation indication域，PDCCHSkipDurationList-R17字段为{1,100，skip to next Monitoring Occasion}；其中，skip to next Monitoring Occasion为第二配置信息，且第二配置信息为PDCCHSkipDurationList-R17字段配置的三个指示PDCCH skipping的候选时长的参数中的第三个参数。第三指示信息和指示的用户设备行为可以如下表7所示：
表7
如上表7所示，当PDCCH monitoring adaptation indication域的比特值为“11”时，终端设备可以根据表7所示的对应关系，确定以skip to next Monitoring Occasion对应的时长跳过PDCCH的监听，即跳过监听，直至下一PDCCH监听周期开始。同理，当PDCCH  monitoring adaptation indication域的比特值为“0”或者“00”时，终端设备可以根据表7所示的对应关系，确定无需跳过监听PDCCH，可以继续监听PDCCH。当PDCCH monitoring adaptation indication域的比特值为“1”或者“01”时，终端设备可以根据表3所示的对应关系，确定需要跳过PDCCH监听的时长为1slot。当PDCCH monitoring adaptation indication域的比特值为“10”时，终端设备可以根据表7所示的对应关系，确定需要跳过PDCCH监听的时长为10slot。
以下对本申请提供的节能方法中的另一个示例性的具体实施例进行介绍。假设数据为XR业务的数据帧，图16中以网络设备和终端设备作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图16中的网络设备也可以是支持该网络设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分网络设备功能的逻辑模块或软件；图16中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端设备功能的逻辑模块或软件。该实施例包括：S1601-S1604：
S1601、网络设备在向终端设备发送的RRC信令中，携带用于配置PDCCH skipping的候选时长的第二配置信息，其中，第二配置信息指示跳过PDCCH的监听直至下一PDCCH监听周期开始。
S1601的具体实现可以参考上文对S1503的介绍，在此不再赘述。
S1602、网络设备向终端设备传输XR业务的数据帧。
S1603、网络设备向终端设备发送DCI，其中携带第三指示信息，第三指示信息指示终端设备根据第二配置信息跳过PDCCH的监听。
S1603的具体实现可以参考上文对S1501和S1503的介绍，在此不再赘述。
S1604、终端设备根据第三指示信息，确定本次需要跳过的PDCCH skipping的时长为第二配置信息指示的候选时长。终端设备跳过PDCCH的监听，直至下一PDCCH监听周期开始。
S1604的具体实现可以参考上文对S1501和S1503的介绍，在此不再赘述。

本申请实施例可以根据上述方法实施例中对通信装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
