Description

一种非连续接收的配置方法及装置
本申请要求于2021年04月20日提交国家知识产权局、申请号为202110427057.X、申请名称为“一种减少PDCCH监测的方法”的中国专利申请的优先权，以及，2021年05月08日提交国家知识产权局、申请号为202110502448.3、申请名称为“一种非连续接收的配置方法及装置”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，尤其涉及一种非连续接收的配置方法及装置。
背景技术
在无线通信***中，在保证数据能够有效传输的前提下为了节省终端设备的功耗，引入了一种非连续接收(discontinuous reception，DRX)机制来控制终端设备监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)的行为。网络设备为终端设备下发DRX配置，其中，DRX配置可以包括DRX周期和持续时间onDuration的配置信息，用于确定终端设备在该DRX周期的onDuration时段内可以持续监听PDCCH获取调度信息。如果终端设备在onDuration时段内没有接收到任何调度信息，则终端设备进入睡眠状态，停止监听PDCCH以节省功耗。
其中，对于扩展现实(extended reality，XR)业务，例如，虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、云游戏(cloud gaming，CG)等，XR业务的特点是数据量较大，数据包到达具有周期性且间隔时间较短，XR业务对于传输时延要求较高，通常要求不小于10ms，否则影响用户体验。
示例性的，某一XR业务为每秒传输60帧图像，即相邻两帧图像对应的数据包的到达时间间隔平均为16.67ms。无论采用现有标准中的哪种DRX周期长度，如现有的DRX周期12ms、14ms、16ms或者20ms等，DRX周期都无法与数据包的到达间隔对齐，因此XR业务数据包的到达时间都会逐渐与DRX周期中配置的onDuration时段发生偏移，以至数据包到达时间处于DRX周期的onDuration时段之外，此时终端设备处于休眠时间不再监听PDCCH，则网络设备需要在下一个DRX周期传输该数据包，从而增大了数据包的传输时延，可能造成终端设备侧的图像卡顿现象，影响XR业务的用户体验。另外，数据包的到达时间间隔平均为16.67ms时，不是时隙长度(如1ms、0.5ms或0.25ms等)的整数倍，会导致数据包的到达时间与时隙边界无法对齐，从而导致onDuration时段与数据包的到达时间无法对齐。

在具体实现时，图1a所示各网元，如：终端设备、网络设备可采用图2所示的组成结构或者包括图2所示的部件。图2为本申请实施例提供的一种通信装置200的结构示意图，当该通信装置200具有本申请实施例所述终端设备的功能时，该通信装置200可以为终端设备或者终端设备中的芯片或者片上***。当通信装置200具有本申请实施例所述的网络设备的功能时，通信装置200可以为网络设备或者网络设备中的芯片或者片上***。

存储器204，用于存储指令。其中，指令可以是计算机程序。
其中，存储器204可以是只读存储器(Read-only Memory，ROM)或可存储静态信息和/或指令的其他类型的静态存储设备，也可以是随机存取存储器(Random Access Memory，RAM)或者可存储信息和/或指令的其他类型的动态存储设备，还可以是电可擦可编程只读存储器(Electrically Erasable Programmable read-only Memory，EEPROM)、只读光盘(Compact Cisc read-only Memory，CD-ROM)或其他光盘存储、光碟存储、磁盘存储介质或其他磁存储设备，光碟存储包括压缩光碟、激光碟、光碟、数字通用光碟、或蓝光光碟等。

本申请实施例中，芯片***可以由芯片构成，也可以包括芯片和其他分立器件。
结合上述图1a中，终端设备在连接态时可以根据网络设备配置的DRX配置信息，进入持续时间onDuration以持续监听PDCCH，或者进入休眠时间，停止监听PDCCH以达到省电的目的。其中，如图1b所示，DRX配置信息可以包括DRX周期(DRX cycle)，用于确定该DRX的周期长度。DRX配置信息还可以包括指示DRX周期的起始位置的信息，例如drx-StartOffset，可以用于确定DRX cycle的起始子帧。DRX配置信息还可以包括持续时间定时器onDurationTimer的配置信息，用于确定终端设备从DRX周期的起始位置开始持续监听PDCCH的时段，也就是从drx-StartOffset指示的起始子帧算起需要监听PDCCH的连续子帧数。
另外，如图1b所示，终端设备还可以在监听到调度初传数据的PDCCH的时候，启动或重启不活动定时器InactivityTimer，该InactivityTimer即为终端设备用于延长激活时间的定时器。根据InactivityTimer可以确定当终端设备成功解码一个指示初传的 用户数据上行或下行PDCCH后，持续位于激活时间的时间长度，即每当终端设备有初传数据被调度，就启动或重启InactivityTimer定时器。
在网络设备向终端设备传输XR或类似XR业务的数据包场景中，如图3a所示，以相邻两帧图像对应的数据包的到达时间间隔平均为16.67ms为例，终端设备侧数据包的理想到达时间间隔可以为16.67ms。
在这种情况下，网络设备可以为该终端设备配置比较接近数据包到达时间间隔的DRX周期长度，例如可以为16ms，则如图3a所示，第一个数据包到达的时刻处于DRX周期的onDuration时段，而第二个数据包由于到达时间间隔为16.67ms，第二个数据包到达的时刻与onDuration的起始时刻的时间距离相比第一个数据包会发生变化。经过若干个数据包后，数据包到达的时刻可能处于DRX周期的onDuration时段之外。由于终端设备在onDuration内未收到数据调度时，会在onDuration之后的时间处于不监听PDCCH的状态，此时，网络设备只能将数据包延迟到下一个DRX周期内进行调度。由于DRX周期长度为16ms，延迟到下一个DRX周期内进行调度会导致终端设备侧XR业务的数据包延迟大于10ms，从而造成卡顿现象，严重影响XR业务的用户体验。
另外，在NR中，支持多种不同类型的子载波间隔，每种子载波间隔对应一个参数μ，如子载波间隔为15kHz，则对应的μ，为0，子载波间隔为30kHz，则对应的μ，为1等。每种子载波间隔对应的时隙slot长度为1/2 μms，即slot长度可以为0.125ms、0.25ms、0.5ms或1ms等。数据包的到达时间间隔平均为16.67ms时，不是时隙长度的整数倍，会导致数据包的到达时间与时隙边界无法对齐，从而导致onDuration时段与数据包的到达时间无法对齐。
另外，考虑到下行传输中，由于数据包从服务器到达基站的路由路径不同，数据包实际到达的时间可能出现抖动(jitter)现象，例如，抖动的时长可能为0～8ms。如图3b所示，数据包的到达时间可能会延迟0～8ms，即使得数据包到达的时间间隔为16.67ms～24.67ms之间波动。如图3b所示，通过将DRX周期中的onDuration时段配置得较长，可以解决由于抖动引起的数据包延迟到达的问题，尽可能使得数据到达时间处于onDuration时段之内。例如，将onDuraiton的长度配置为可以覆盖到jitter可能的延迟范围，使得onDuration的长度足以覆盖数据包到达的所有可能时间段，如onDuration时段配置为10ms。但是，DRX的持续时间配置过长会导致终端设备的激活时间过长，终端设备监听到初传PDCCH还会启动InactivityTimer以延长激活时间，与此同时，每个数据包的传输时间可能较短(例如小于5ms)，如此，终端设备会在激活时间的大部分时段内进行无效的PDCCH监测(即监测了PDCCH但是没有收到数据调度)，难以达到节能的效果。
基于上述问题，下面结合图1a所示通信***，对本申请实施例提供的实施方式进行描述。其中，下述实施例中的各设备可以具有图2所示部件。其中，本申请各实施例之间涉及的动作，术语等均可以相互参考，不予限制。本申请的实施例中各个设备之间交互的消息名称或消息中的参数名称等只是一个示例，具体实现中也可以采用其他的名称，不予限制。
本申请实施例提供一种非连续接收的配置方法，应用于如图1a所示的通信***。 如图4所示，该方法可以包括：
401：网络设备向终端设备发送DRX配置信息。
DRX配置信息至少包括一个DRX的配置信息，例如DRX配置信息可以包括第一DRX的配置信息，第一DRX的配置信息包括第一DRX周期长度。
其中，根据DRX的配置信息确定的终端设备在DRX的起始位置监测PDCCH的时间也称为持续时间，第一DRX周期中的持续时间可以为第一onDuration，下一个第一DRX周期中的持续时间可以为第二onDuration，即第二onDuration为第一onDuration的下一个onDuration。第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔大于第一DRX周期长度。
或者，在另一种实施方式中，DRX配置信息还可以包括第二DRX的配置信息，第二DRX的配置信息可以包括第二DRX周期长度。
需要说明的是，本申请的实施例中所述的DRX周期的起始位置或者DRX周期的onDuration起始位置具体可以指起始时隙，即DRX周期开始的第一个时隙。
其中，第一DRX周期中的持续时间可以为第二onDuration，第二DRX周期中的持续时间可以为第一onDuration，第二onDuration为第一onDuration的下一个onDuration。第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔大于第一DRX周期长度。
进一步的，DRX配置信息还可以包括DRX模式(DRX pattern)。该DRX模式用于指示至少一个第一DRX和至少一个第二DRX的排列顺序。或者，该DRX模式用于指示至少一个第一DRX周期和至少一个第二DRX周期的排列顺序。或者，该DRX模式用于指示第一DRX周期和第二DRX周期的排列顺序以及各自的个数。示例性的，该DRX模式可以配置排列顺序为{第一DRX、第二DRX、第一DRX}，或者，配置排列顺序为{第一DRX、第二DRX、第二DRX}的等。
可选的，DRX配置信息可以承载于无线资源控制(Radio Resource Control，RRC)信令。
402：终端设备接收来自网络设备的DRX配置信息，根据DRX配置信息确定第一持续时间和第二持续时间的起始位置，在第一持续时间和第二持续时间内接收下行信号。
终端设备可以根据DRX配置信息，在DRX周期的起始时刻启动onDuration定时器，进入激活时间持续监听PDCCH，直到onDuration定时器超时，若终端设备未收到调度信息，则终端设备进入非激活时间；或者终端设备在onDuration内监测到PDCCH，启动InactivityTimer延长激活时间。
具体的，终端设备可以根据DRX配置信息中包括的参数，确定第一DRX周期的起始位置，以及第一DRX周期的onDuration的起始位置。
在上述的一种实施方式中，终端设备可以根据第一DRX的配置信息、第二DRX的配置信息以及DRX模式，在至少一个第一DRX的onDuration和至少一个第二DRX的onDuration时段内接收下行信号。
从而，通过本申请的上述实施方式，网络设备可以根据终端设备传输数据的帧率，为终端设备灵活配置对应的DRX，从而尽可能使得DRX周期的onDuration时段匹配 数据包的达到时间，从而可以降低数据传输的延迟，保证用户体验的同时为终端设备节能。
在一种实施方式中，网络设备可以为终端设备配置两个不同周期长度的DRX，并通过配置对应的DRX模式，使得终端设备DRX周期的onDuration时段可以匹配数据包的达到时间。
结合不同的数据帧率，根据网络设备配置的算法可以得到每个DRX周期的起始位置。若业务的数据帧率为1000/A fps(frame per second)，即数据包的到达时间间隔为A ms，网络设备可以配置第一DRX的周期长度为B ms，其中B<A，第二DRX的周期长度为C ms，其中C>A，可以找到正整数M和正整数N，使M*B+N*C＝(M+N)*A得以满足。此时，网络设备可以配置DRX patter为{M个第一DRX、N个第二DRX}
示例性的，以数据的帧率为60fps，即数据包的到达时间间隔为16.67ms为例，介绍本申请的一种可能的实现方式。
网络设备向该终端设备发送的DRX配置信息包括：第一DRX的周期长度为16ms，第二DRX的周期长度为17ms。进一步的，DRX配置信息还包括DRX模式，例如可以为：排列顺序为{第一DRX，第二DRX，第二DRX}。
图5示出了终端设备的DRX配置方式，DRX-0的周期长度为16ms，DRX-1的周期长度为17ms，DRX-2的周期长度为17ms，DRX-3的周期长度为16ms，如此循环。其中，DRX-1的起始位置与第二个数据包到达时间相差0.67ms，到DRX-2的起始位置与第三个数据包到达时间差距缩小到0.34ms，到DRX-3的起始位置与数据帧到达时间又可以重新匹配上。
上述实施方式种，通过配置DRX周期1的长度为16ms和DRX周期2的长度为17ms两个DRX周期，并按照一定的排列顺序进行配置，例如，可以配置为：周期1-周期2-周期2，或者，配置为周期2-周期1-周期2等，可以达到每个DRX周期的起始位置与数据包的到达时间差距小于或等于0.67ms，从而可以降低数据传输的延迟。
具体的，网络设备可以为终端设备预先配置DRX周期的起始位置drx-StartOffset的算法，以使得终端设备可以根据该算法，计算出DRX周期的起始位置对应的***帧号(System Frame Number，SFN)以及对应的子帧号。
示例性的，DRX周期的起始位置对应的SFN以及子帧号满足如下算法。
1、若DRX周期的索引index为3的倍数，即n mod 3＝0，
则
Figure PCTCN2022087464-appb-000001
2、若DRX周期的索引index不是3的倍数，即n mod 3≠0，
则
Figure PCTCN2022087464-appb-000002
其中，n表示DRX周期的索引，n可以取值为0、1、2、3、4...等整数。subframe number表示子帧号，一个SFN中可以包括10个子帧。L i表示DRX配置的DRX模式中第i个DRX周期的周期长度，其中，本申请如图5所示的实施方式中，DRX配置的DRX模式中包括三个DRX，因此，i取值可以为0、1和2。n％3表示n对3取余数得到的值。
示例性的，图5所示中，L 0＝16ms，L 1＝17ms，L 2＝17ms，则
Figure PCTCN2022087464-appb-000003
的取值可以为16ms或33ms。
因此，当n mod 3＝0，即在0ms、50ms、100ms等时间，根据[(SFN×10)+subframe number]mod(50)确定DRX周期起始位置对应的SFN及子帧号。当n mod 3≠0，即在16ms、33ms、66ms、83ms等时间，图5中DRX-1的起始位置相当于根据[(SFN×10)+subframe number]mod(50)确定DRX周期起始位置上偏移DRX-0的周期长度，DRX-2的起始位置相当于再偏移DRX-1的周期长度，按此方法可以确定各个DRX周期的起始位置对应的SFN及子帧号。
再以数据的数据帧率为90fps，即数据包的到达时间间隔为11.11ms为例进行介绍。网络设备向该终端设备发送的DRX配置信息包括：第一DRX的周期长度为11ms，第二DRX的周期长度为12ms。进一步的，DRX配置信息还包括DRX模式，例如可以为：{8个第一DRX，1个第二DRX}的顺序。
类似的，DRX-0～DRX-7的周期长度为11ms，DRX-8的周期长度为12ms，DRX-9～DRX-16的周期长度为11ms，DRX-17的周期长度为12ms，如此循环。其中，DRX-1～DRX-8中各个DRX的起始位置与数据包到达时间相差0.11ms、0.22ms……0.88ms，到DRX-9的起始位置与数据帧到达时间又可以重新匹配上。
具体的，网络设备可以为终端设备预先配置DRX周期的起始位置drx-StartOffset的算法，以使得终端设备可以根据该算法，计算出DRX周期的起始位置对应的***帧号(System Frame Number，SFN)以及对应的子帧号。
示例性的，DRX周期的起始位置对应的SFN以及子帧号满足如下算法。
1、若DRX周期的索引index为9的倍数，即n mod 9＝0，
则
Figure PCTCN2022087464-appb-000004
2、若DRX周期的索引index不是9的倍数，即n mod 9≠0，
则
Figure PCTCN2022087464-appb-000005
其中，n表示DRX周期的索引，n可以取值为0、1、2、3、4...等整数。subframe number表示子帧号，一个SFN中可以包括10个子帧。L i表示DRX配置的DRX模式中第i个DRX周期的周期长度，其中，本申请如图5所示的实施方式中，DRX配置的DRX模式中包括9个DRX，因此，i取值可以为0～8。n％9表示n对9取余数得到的值。
在另一种实施方式中，上述步骤401中的DRX配置信息还可以包括第一偏移值，该第一偏移值可以用于确定第二onDuration的起始位置。也就是说，网络设备可以为终端设备配置一个DRX的偏移值，用于确定DRX周期中onDuration的起始位置。
进一步的，终端设备可以根据第一DRX周期长度与第一偏移值确定第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔。
具体的，终端设备可以判断当满足一定条件时，根据第一DRX周期长度与第一偏移值的和确定第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔，即确定出第二onDuration的起始位置。
示例性的，以数据包的到达时间间隔为16.67ms，第一DRX周期长度为16ms为例，介绍本申请的一种实施方式。其中，第一偏移值f1可以配置为2ms，所述条件可以为判断DRX周期的索引index是否为3的倍数。
当DRX周期的索引n不是3的倍数时，DRX周期的起始位置对应的SFN及子帧号满足：
[(SFN×10)+subframe number]mod(DRX_Cycle)＝drx-StartOffset；其中，DRX_Cycle为DRX的周期长度。
当DRX周期的索引n是3的倍数时，DRX周期的起始位置对应的SFN及子帧号满足：
[(SFN×10)+subframe number]mod(DRX_Cycle)＝drx-StartOffset+f1。
或者，上述实施方式还通过另一种方式确定DRX周期的起始位置对应的SFN及子帧号：
[(SFN×10)+subframe number]mod(DRX_Cycle)＝drx-StartOffset+f1，其中，n mod 3＝0时，f1＝2ms；n mod 3≠0时，f1＝0。
上述实施方式示出了网络设备为终端设备配置一种DRX周期的情况，进一步的，当网络设备为终端设备配置DRX长周期drx-LongCycle和DRX短周期drx-ShortCycle的方式下，DRX周期的起始位置对应的SFN及子帧号如下所述。
短周期DRX的起始位置对应的SFN及子帧号满足：
[(SFN×10)+subframe number]mod(drx-ShortCycle)＝(drx-StartOffset+f1)mod(drx-ShortCycle)；
长周期DRX的起始位置对应的SFN及子帧号满足：
[(SFN×10)+subframe number]mod(drx-LongCycle)＝drx-StartOffset+f1；其中，n mod 3＝0时，f1＝2ms；n mod 3≠0时，f1＝0。
如图6所示，网络设备配置的DRX周期为16ms，网络设备配置的第一偏移值可以为2ms，终端设备可以在第四个DRX周期(即DRX-3)的onDuration的起始位置偏移2ms，以使得第四个DRX周期的onDuration重新与数据包的到达时间匹配上。
上述实施方式，终端设备每隔三个DRX周期可以通过第一偏移值来调节DRX周期的onDuration起始位置，使得下一个DRX周期的起始位置可以与数据包的到达时间达到匹配或者基本匹配的效果，以避免数据传输的时延过大。
另外，对于其他的数据传输帧率，如30fps或者90fps等，也可以通过上述的这种实施方式，通过每隔N个DRX周期配置一定的第一偏移值来调节DRX周期的onDuration起始位置，从而使得每隔N个DRX周期，DRX周期的起始位置可以与数据包的到达时间达到匹配或者基本匹配的效果。其中，第一偏移值或者N可以由网络设备预先为终端设备配置好，或者，网络设备为终端设备配置对应的算法，终端设备即可以根据预先配置，得到每个DRX周期的起始位置。
示例性的，帧率为30fps，即两个数据包的到达时间间隔可能为33.33ms，则网络设备可以配置DRX周期为34ms，终端设备可以每隔3个DRX周期通过配置一定的第一偏移值来调节DRX周期的onDuration起始位置，例如，f1＝-2ms，即第四个DRX周期的起始位置向前偏移2ms，以达到与数据包的达到时间近似匹配的效果。
或者，网络设备可以配置DRX周期为33ms，终端设备可以每隔3个DRX周期通过配置一定的第一偏移值来调节DRX周期的onDuration起始位置，例如，f1＝1ms。即第四个DRX周期的起始位置向后偏移1ms，以达到与数据包的达到时间近似匹配的 效果。
另一示例中，如帧率为90fps，即两个数据包的到达时间间隔可能为11.11ms，则网络设备可以配置DRX周期为11ms，终端设备可以每隔9个DRX周期通过配置一定的第一偏移值来调节DRX周期的onDuration起始位置，例如，f1＝1ms，即第十个DRX周期的起始位置向后偏移1ms，以达到与数据包的达到时间近似匹配的效果。
在另一种实施方式中，终端设备还可以通过第二偏移值来确定第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔。其中，该第二偏移值可以是前述的步骤401中，网络设备向终端设备发送的DRX配置信息中携带的，也可以是网络设备通过其他配置信息为终端设备配置的。从而终端设备可以根据第二偏移值与第一DRX周期长度确定第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔，从而确定第二onDuration的起始位置。
进一步的，第二偏移值至少根据第二onDuration所在的DRX周期的索引值确定，第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔可以等于第一DRX周期长度与第二偏移值的和。
在一种实施方式中，该第二偏移值f2满足：f2＝floor(D×n)-floor(D×(n-1))，其中，floor(x)函数用于对参数x向下取整，n为第二onDuration所在的DRX周期的索引值，n-1为第一onDuration所在的DRX周期的索引值，D可以根据第一配置信息确定。
其中，所述第一配置信息可以携带于步骤401的DRX配置信息中，也可以是网络设备为终端设备下发的其他配置信息(例如其他RRC信令)中携带的。本申请对此不作具体限定。
具体的，D可以为DRX周期长度与数据包到达时间间隔之间的差值，第一配置信息可以包括D的值；或者第一配置信息包括数据包的到达时间间隔，从而终端设备可以根据数据报的到达时间间隔与DRX配置信息中包括的DRX周期长度的差值，计算得到D的值。示例性的，数据包的到达时间间隔为16.67ms，DRX周期长度为16ms时，D的值即为0.67ms。
进一步的，终端设备确定每个DRX周期的起始位置包括。其中，短周期DRX的起始位置对应的SFN及子帧号满足：[(SFN×10)+subframe number]mod(drx-ShortCycle)＝(drx-StartOffset+f2_1)mod(drx-ShortCycle)；
长周期DRX的起始位置对应的SFN及子帧号满足：
[(SFN×10)+subframe number]mod(drx-LongCycle)＝drx-StartOffset+f2_1。
其中，f2_1＝floor(D×n)。
示例性的，如图7所示，当n＝0时，16×0+floor(0.67×0)＝0，DRX-0的起始位置为0ms。n＝1时，16×1+floor(0.67×1)＝16，DRX-1的起始位置在16ms，此时DRX-1的起始位置与DRX-0的起始位置的间隔为16ms，与DRX周期长度16ms相同，即f2＝0ms，总的偏移值f2_1为0ms。n＝2时，16×2+floor(0.67×2)＝33，DRX-2的起始位置在33ms，此时DRX-2的起始位置与DRX-1的起始位置的间隔为17ms，相比DRX周期长度16ms发生了1ms的偏移，即f2＝1ms，总的偏移值f2_1为1ms。n＝3时，16×3+floor(0.67×3)＝50，起始位置在50ms，此时DRX-3的起始位置与DRX-2的起 始位置的间隔为17ms，相比DRX周期长度16ms也发生了1ms的偏移，即f2＝1ms，终端设备直至DRX-3时，总的偏移值f2_1为2ms。n＝4时，16×4+floor(0.67×4)＝66，DRX-4的起始位置在66ms，此时DRX-4的起始位置与DRX-3的起始位置的间隔为16ms，与DRX周期长度16ms相同，即f2＝0ms，总的偏移值f2_1为2ms。n＝5时，16×5+floor(0.67×5)＝83，DRX-5的起始位置在83ms，此时DRX-5的起始位置与DRX-4的起始位置的间隔为17ms，相比DRX周期长度16ms发生了1ms的偏移，即f2＝1ms，总的偏移值f2_1为3ms。由图示的DRX配置可见，DRX-3至DRX-5是重复DRX-0至DRX-2的相应配置，从而可以达到每三个DRX周期之后就可以使得数据包的到达时间与下一个DRX周期的开始时间相匹配或者近似匹配。
另外，网络设备为终端设备配置的DRX配置信息中还可以包括onDuration的起始位置的偏移值，例如，drx-slotOffset，即一个DRX周期的起始位置并不一定是onDuration的起始位置，而应该是该DRX周期的起始位置加上配置的偏移值drx-slotOffset。本申请的实施例中可以通过动态调节DRX周期的起始位置与onDuration的起始位置之间的偏移值，来调节DRX周期中onDuration的起始位置，以使得DRX周期中onDuration的起始位置尽可能与数据包的到达时间匹配。
在本申请的一种可能的实施方式中，第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔还可以根据第三偏移值确定。
进一步的，终端设备可以根据第一DRX周期长度、第二偏移值和第三偏移值的和确定第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔。
也就是说，终端设备确定第二onDuration的起始位置对应的子帧后，还要根据第三偏移值确定第二onDuration的起始位置在该子帧中的具***置。具体的，第一onDuration的起始位置与第二onDuration的起始位置之间的时间间隔可以先根据第一DRX周期长度和第二偏移值，确定间隔的子帧个数，并根据第三偏移值和drx-SlotOffset的和确定最终的间隔，其中drx-SlotOffset为网络设备配置的onDuration的起始位置的偏移值。
在一种实施方式中，第三偏移值f3满足：f3＝floor(2 μ×(D×n-floor(D×n)))/2 μ-floor(2 μ×(D×(n-1)-floor(D×(n-1))))/2 μ，其中，floor(x)函数用于对参数x向下取整，n表示第二DRX周期的索引值，μ为子载波间隔对应的参数。D可以根据第一配置信息确定，具体可以参照前述实施方式中得到D的值，此处不再赘述。
此时，终端设备根据下列公式确定onDuration所在的目标子帧：
短周期DRX的起始位置对应的SFN及子帧号满足：[(SFN×10)+subframe number]mod(drx-ShortCycle)＝(drx-StartOffset+f3_1)mod(drx-ShortCycle)；
长周期DRX的起始位置对应的SFN及子帧号满足：[(SFN×10)+subframe number]mod(Drx-LongCycle)＝drx-StartOffset+f3_1。
第二onDuration的起始位置为该目标子帧起始位置后drx-SlotOffset+f3_1的位置，其中，drx-SlotOffset为网络设备配置的onDuration的起始位置的偏移值，f3_1＝floor(2 μ×(D×n-floor(D×n)))/2 μ。
具体的，仍以数据包到达时间间隔为16.67ms，网络设备配置的DRX周期为16ms 为例进行介绍，假设μ＝1且网络设备配置的drx-SlotOffset＝0，则D＝0.67，则n＝0时，f3_1＝0ms；n＝1时，f3_1＝0.5ms；n＝2时，f3_1＝0ms；n＝3时，f3_1＝0ms；n＝4时，f3_1＝0.5ms；n＝5时，f3_1＝0ms，如此循环。
图8所示，当n＝0时，第一DRX周期长度+f2_1＝0+0＝0ms，DRX-0的起始位置为0ms，第一DRX周期长度+f2_1+f3_1＝0+0+0＝0，DRX-0的onDuration的起始位置在0ms。n＝1时，第一DRX周期长度+f2_1＝16+0＝16ms，DRX-1的起始位置在16ms，第一DRX周期长度+f2_1+f3_1＝16+0+0.5＝16.5ms，DRX-1的onDuration的起始位置在16.5ms。n＝2时，第一DRX周期长度+f2_1＝16+1＝17，DRX-2的起始位置在16+17＝33ms，此时DRX-2的起始位置与DRX-1的起始位置的间隔为17ms，第一DRX周期长度+f2_1+f3_1＝16+1+0＝17，DRX-2的onDuration的起始位置在17ms。n＝3时，第一DRX周期长度+f2_1＝16+1＝17ms，DRX-3的起始位置在33+17＝50ms，此时DRX-3的起始位置与DRX-2的起始位置的间隔为17ms，第一DRX周期长度+f2_1+f3_1＝16+1+0＝17，DRX-3的onDuration的起始位置在50ms。n＝4时，第一DRX周期长度+f2_1＝16+0＝16ms，DRX-4的起始位置在50+16＝66ms,第一DRX周期长度+f2_1+f3_1＝16+0+0.5＝16.5，DRX-4的onDuration的起始位置在66.5ms。n＝5时，第一DRX周期长度+f2_1＝16+1＝17ms，DRX-5的起始位置在66+17＝83ms,第一DRX周期长度+f2_1+f3_1＝16+1+0＝17，DRX-4的onDuration的起始位置在83ms。由图8示的DRX配置可见，使得onDuration的起始位置与数据到达时间的差值更小，通过动态调节DRX周期的起始位置与onDuration的起始位置之间的偏移值，可以进一步使得数据包的到达时间与DRX周期的开始时间达到匹配或者近似匹配的效果。
此外，还有一种可能实施方式，其中，第三偏移值f3满足：
f3＝floor(32×(D×n-floor(D×n)))/32-floor(32×(D×(n-1)-floor(D×(n-1))))/32，其中，n表示第二DRX周期的索引值，μ为子载波间隔对应的参数。D可以根据第一配置信息确定，具体可以参照前述实施方式中得到D的值，此处不再赘述。
此时，终端设备根据下列公式确定onDuration所在的目标子帧：
短周期DRX的起始位置对应的SFN及子帧号满足：[(SFN×10)+subframe number]mod(drx-ShortCycle)＝(drx-StartOffset+f2_1)mod(drx-ShortCycle)；
长周期DRX的起始位置对应的SFN及子帧号满足：[(SFN×10)+subframe number]mod(Drx-LongCycle)＝drx-StartOffset+f2_1。
第二onDuration的起始位置为该目标子帧起始位置后drx-SlotOffset+f3_1的位置，其中，drx-SlotOffset为网络设备配置的onDuration的起始位置的偏移值，f3_1＝floor(32×(D×n-floor(D×n)))/32。
具体的，仍以数据包到达时间间隔为16.67ms，网络设备配置的DRX周期为16ms,μ＝1且网络设备配置的drx-SlotOffset＝0为例进行介绍，D＝0.67，则n＝0时，f3_1＝0ms；n＝1时，f3_1＝21/32＝0.66ms；n＝2时，f3_1＝10/32＝0.31ms；n＝3时，f3_1＝0ms；n＝4时，f3_1＝0.66ms；n＝5时，f3_1＝0.31ms，如此循环。可以通过更为精准的动态偏移值，达到数据包的到达时间与DRX周期的开始时间匹配或者近似匹配的效果。
另外，结合前述数据传输中的抖动现象可能造成的数据传输延迟，本申请还提供另一种非连续接收的配置方法，通过网络设备向终端设备下发指示终端设备开始监测 PDCCH的位置，来缩短监测时间。
如图9所示，该方法包括：
901：网络设备确定第一指示信息。
其中，第一指示信息用于终端设备确定在持续时间onDuration内监测PDCCH的位置。
具体的，第一指示信息可以用于终端设备确定监测PDCCH的开始位置，如指示终端设备在onDuration内开始监测PDCCH的时隙位置。
示例性的，第一指示信息为2个比特时，可以用第一指示信息为00表示在DRX周期onDuration的第一位置开始监测PDCCH，第一指示信息为01表示在DRX周期onDuration的第二位置开始监测PDCCH，第一指示信息为10表示在DRX周期onDuration的第三位置开始监测PDCCH，第一指示信息为11表示在DRX周期onDuration的第四位置开始监测PDCCH。
需要说明的是，上述第一指示信息指示的时隙位置可以是网络设备对DRX周期onDuration的长度预先进行划分，例如分成四等分，每一种指示信息分别对应一个onDuration分段的起始时隙位置。或者，第一指示信息还可以指示开始监测PDCCH的时隙的索引值。或者，网络设备可以根据一定的算法对该终端设备当前待发送数据包的可能时间进行预估，得到监测PDCCH的具***置，本申请对此不作具体限定。
或者，第一指示信息还可以用于终端设备在配置的DRX的onDuration内开始监测PDCCH的偏移值。例如，第一指示信息为01表示在DRX周期onDuration的开始位置偏移offset1开始监测PDCCH等。
902：网络设备向终端设备发送第一指示信息。
具体的，网络设备向终端设备发送的第一指示信息可以位于onDuration之前，如在onDuration之前的一个或多个时隙，或者，第一指示信息可以位于onDuration的起始位置，例如位于onDuration的起始时隙的开头。
903：终端设备根据第一指示信息确定在onDuration内监测PDCCH的位置。
方式1中，终端设备可以一直监测PDCCH到激活时间结束，其中，激活时间可以包括onDuration时段，以及终端设备监测到PDCCH之后启动的InactivityTimer时段。或者，方式2中，终端设备可以根据网络设备预先配置的监测时间监测PDCCH，也就是说，每一次终端设备收到第一指示信息，都可以根据第一指示信息指示的位置在该预先配置的监测时间内监测PDCCH。具体可以参照如图10所示的两种方式：方式1和方式2。本申请实施方式中对此不作具体限定。
进一步的，在一种实施方式中，第一指示信息还用于指示在onDuration内监测PDCCH的时间长度，也就是说，第一指示信息中除了可以包括开始监测PDCCH的位置，还可以包括开始监测PDCCH的时间长度。具体的，即第一指示信息可以包括onDuration内监测PDCCH的开始时隙以及监测PDCCH的时隙个数。
例如，第一指示信息为2个比特时，网络设备的第一指示信息可以配置如下表1。
表1.第一指示信息的取值与指示内容的对应关系
第一指示信息的取值 第一指示信息的指示内容
00 第一开始位置，第一长度
01 第二开始位置，第二长度
10 第三开始位置，第三长度
11 第四开始位置，第四长度
在另一种实施方式中，第一指示信息还用于指示在onDuration内监测PDCCH的结束位置，也就是说，第一指示信息中除了可以包括开始监测PDCCH的位置，还可以包括开始监测PDCCH的结束位置。
另外，若终端设备被配置了可以接收网络设备的第一指示信息，而在对应的位置并未收到第一指示信息，则终端设备可以在onDuration的起始位置开始监测PDCCH；或者，终端设备在该onDuration不监测PDCCH；或者终端设备根据网络设备发送的配置信息，确定终端设备的行为为上述二者中的哪一种。
上述实施方式，网络设备可以通过向终端设备发送具体的监测PDCCH的指示信息，从而用于缩短终端设备监测PDCCH的时间长度，降低终端设备的功耗。
在另一种可能的实现方式中，第一指示信息可以用于指示终端设备在DRX周期的onDuration内M个区域中的N个区域内监测PDCCH，其中，onDuration被划分为M个区域，其中，M≥2，N满足：1≤N≤M。
示例性的，M为2，即表示onDuration被划分为前后两个区域，第一指示信息可以通过一个比特来指示监测PDCCH的位置。例如，第一指示信息为0表示在onDuration的前半段区域内监测PDCCH，第一指示信息为1表示在onDuration的后半段区域内监测PDCCH。
具体的，当M为大于2的正整数时，第一指示信息可以用于指示终端设备在DRX周期的onDuration内M个区域中的第N个区域内监测PDCCH。例如，M为4，则第一指示信息为01用于指示在onDuration内4个区域中的第2个区域内监测PDCCH。
示例性的，如图11所示，终端设备可以在onDuration起始位置接收到第一指示信息，将onDuration分为A和B两个区域，若第一指示信息为0，则终端设备可以开始在A区域内监测PDCCH。若第一指示信息为1，终端设备可以开始在B区域内监测PDCCH。
进一步的，网络设备还可以向该终端设备发送第二指示信息，第二指示信息指示终端设备在N个区域内监测PDCCH的位置。
也就是说，可以将onDuration时段划分为第一区域和第二区域，其中，第一区域又可以划分为第一子区域和第二子区域等。第一指示信息可以用于指示在onDuration内的第一区域内监测PDCCH，第二指示信息可以用于指示在第一区域内的第一子区域 内监测PDCCH。
示例性的，如图12所示，终端设备可以在onDuration起始位置接收到第一指示信息，将onDuration分为A和B两个区域，若第一指示信息为0，则终端设备可以开始在A区域内监测PDCCH。若第一指示信息为1，终端设备在B区域的起始位置接收第二指示信息，将B区域进一步分为C和D两个区域，若第二指示信息为0，则终端设备开始在C区域内监测PDCCH；若第二指示信息为1，则终端设备在D区域内监测PDCCH。
进一步的，在上述的实施方式中，网络设备可以通过确认目标终端设备的数据包是否到达，来配置第一指示信息指示的内容，即网络设备可以将onDuration的起始位置配置于数据包到达的最早位置，或者将onDuration的起始位置配置于数据包到达的最早位置之后。此时onDuration的长度可以配置为小于或者等于jitter的取值范围，例如，onDuration小于或者等于8ms。如网络设备确定该终端设备的数据包已到达，可以通过第一指示信息指示终端设备在onDuration前半段监测PDCCH；否则，由于onDuration的长度已经覆盖jitter范围，所以在onDuration结束之前，必然有数据包到达，可以通过第一指示信息指示终端设备在onDuration后半段监测PDCCH。
上述本申请的实施方式，网络设备通过指示信息，可以至少将终端设备监测PDCCH的时间缩短一半，且可以将数据传输时延控制在0.5*onDuration之内。通过较小的信令开销，达到缩短终端设备监测PDCCH时间长度、降低终端设备的功耗的效果。
另外，本申请还提供一种非连续接收的配置方法，通过网络设备向终端设备指示终端设备结束监测PDCCH的位置，从而缩短无效的监测时间，为终端设备节省功耗。
在一种实施方式中，可以定义终端设备停止监测PDCCH的规则，则终端设备可以根据该规则确定停止监测PDCCH。
其中，终端设备可以在DRX周期内onDuration结束前的时刻停止监测PDCCH，即终端设备可以根据预先定义的规则确定在onDuration结束前停止监测PDCCH，提前进入休眠状态。
具体的，该停止监测PDCCH的规则具体可以为：终端设备确定在InactivityTimer超时后停止监测PDCCH，或者终端设备确定在InactivityTimer超时时停止监测PDCCH。例如，指示终端设备在第一时刻停止监测PDCCH，其中，第一时刻可以为终端设备的InactivityTimer超时的时刻，或者InactivityTimer超时之后的时刻。
示例性的，如图13所示，终端设备可以在DRX周期的onDuration内，确定InactivityTimer超时后停止监测PDCCH，即终端设备在原有onDuration的后续时段不再监测PDCCH，提前进入休眠状态，缩短了持续监测PDCCH的时长。
需要说明的是，在本申请的实施例中，所述终端设备在DRX周期的onDuration内，等同于终端设备的onDurationTimer未超时。也就是说，终端设备在InactivityTimer超时的时候或者超时之后，停止监测PDCCH，具体可以包括：所述终端设备在DRX周期的onDurationTimer未超时的情况下，InactivityTimer超时的时候或者超时之后，停止监测PDCCH。
进一步的，网络设备可以通过向终端设备发送第二配置信息，用于为该终端设备配置或启用该停止监测PDCCH的规则，从而终端设备可以根据该第二配置信息，启用该停止监测PDCCH的规则，如终端设备确定在InactivityTimer超时后即停止监测PDCCH，进入休眠状态。可选的，该第二配置信息为RRC信令。
上述实施方式中，网络设备可以通过与终端设备预先确定停止监测PDCCH的规则，使得该终端设备确定InactivityTimer超时即可停止监测PDCCH。其中，该终端设备在onDuration时段内已有数据包到达，因此启动InactivityTimer，此时根据XR或类似XR业务的传输特性，该DRX周期内不会再有其他的数据包达到，因此，终端设备可以在InactivityTimer超时之后，提前终止onDuration时段，或者提前将onDurationTimer停止运行，终端设备不再监听PDCCH，进入休眠状态从而达到省电的目的。另一种方式中，也可以通过其他定时器来控制停止监测PDCCH的行为。例如，网络设备可以为终端设备配置不同于InactivityTimer的第一定时器，终端设备确定在该第一定时器超时后停止监测PDCCH，或者终端设备确定在该第一定时器超时时停止监测PDCCH。具体的，终端设备可以在该第一定时器超时之后，提前终止onDuration时段，或者提前将onDurationTimer停止运行。另外，终端设备还可以在该第一定时器超时之后，提前将InactivityTimer停止运行，终端设备不再监听PDCCH，进入休眠状态从而达到省电的目的。上述说明同样可以适用于下述的实施方式。
NR支持混合自动重传请求(hybrid automatic repeat request，HARQ)重传，具体的HARQ过程如下：
对于下行数据传输，终端设备会向网络设备发送HARQ反馈，用于指示PDSCH是否接收成功。如果网络设备确定终端设备解码PDSCH失败，网络设备可以调度PDSCH的重传。由于网络设备确定HARQ反馈中携带的内容(即，终端设备接收PDSCH失败)，以及网络设备发送PDCCH以调度PDSCH的重传需要一定的时间，因此在该段时间内网络设备一定不会调度数据包的重传，终端设备在这段时间内即使监测该数据包的重传调度，也不会收到重传调度。因此目前标准上定义了HARQ往返时间(round trip time，RTT)定时器(timer)。当终端设备向网络设备发送否定应答(negative acknowledgement，NACK)之后，会启动HARQ RTT定时器。在该HARQ RTT定时器运行的时间内，终端设备不期望收到对应数据包的重传。标准上还定义了HARQ重传定时器(retransmission timer)，在HARQ RTT定时器超时之后，HARQ重传定时器会启动。若终端设备向网络设备发送NACK，在HARQ重传定时器运行的时间内，终端设备会监测并且期望收到对应数据包的重传。
对于上行数据传输，NR不支持HARQ反馈。当网络设备接收终端设备发送的PUSCH传输失败后，网络设备可以直接发送调度PUSCH重传的PDCCH。类似于下行传输，NR标准对于上行传输也定义了HARQ RTT定时器和HARQ重传定时器。但是由于上行传输没有HARQ反馈，终端设备在PUSCH发送完毕后会立刻启动HARQ RTT定时器。在该HARQ RTT定时器运行的时间内，终端设备不期望收到对应数据包的重传。而HARQ重传定时器与下行传输类似，在HARQ RTT定时器超时之后，HARQ重传定时器会启动，在HARQ重传定时器运行的时间内，终端设备会监测并且期望收到对应数据包的重传。
另外，为了支持多个数据包的并行处理，NR中支持多个HARQ进程(HARQ process)，其中每个进程可以对应一个数据包，多个进程对应的数据包被并行处理。无论一个HARQ进程对应的数据包是否传输成功，都不会影响另一个HARQ进程对应的数据包的传输。为了保证各个HARQ进程互相不影响，前面提到的HARQ RTT定时器以及HARQ重传定时器都是针对每个HARQ进程(per HARQ process)的。即网络设备会为每个HARQ进程配置对应的HARQ RTT定时器以及HARQ重传定时器。目前，NR中，上行传输最多存在16个HARQ进程，下行传输最多存在16个HARQ进程。
前面所述的方法中，仅仅讨论了InactivityTimer与onDurationTimer的关系，并未讨论InactivityTimer对HARQ重传定时器的影响。
在一种可能的实施方式中，InactivityTimer超时后，终端设备在HARQ重传定时器运行的时间内，监测PDCCH。也就是说，若终端设备向网络设备发送NACK，则在InactivityTimer超时后且HARQ重传定时器运行的时间内，终端设备监测PDCCH，可以直到HARQ重传定时器超时的时候或者超时之后，停止监测PDCCH。
通过这种方法，如果上行或下行数据包传输失败需要重传，可以在HARQ重传定时器运行的时间内快速完成重传，降低数据传输时延。具体的，上行或下行数据包可以包括通过DCI动态调度(dynamic grant，DG)的数据包，也可以包括通过CG(configured grant，配置授权)或SPS(semi-persistence scheduling，半静态调度)传输的数据包。
需要说明的是，InactivityTimer的运行与HARQ重传定时器的运行不会相互影响，二者的运行时间可能重合也可能不重合。例如，InactivityTimer的长度较长，和/或HARQ RTT定时器的长度较短时，有可能在InactivityTimer超时前，HARQ RTT定时器已经超时，同时HARQ重传定时器会启动，此时，InactivityTimer与HARQ重传定时器的运行时间会重合。若InactivityTimer超时前，HARQ重传定时器已经超时，则终端设备会在InactivityTimer运行的全部时间(其中包含HARQ重传定时器运行的时间)内都监测PDCCH；若InactivityTimer超时后，HARQ重传定时器才超时，则终端设备会在InactivityTimer运行的全部时间内监测PDCCH，并且根据上述方法在HARQ重传定时器运行的剩余时间内也监测PDCCH。再例如，InactivityTimer的长度较短，和/或HARQ RTT定时器的长度较长时，有可能在InactivityTimer超时后HARQ RTT定时器才超时，即InactivityTimer超时HARQ重传定时器才会启动，此时，InactivityTimer与HARQ重传定时器的运行时间不会重合。此时，终端设备会在InactivityTimer运行的全部时间内监测PDCCH，并且根据上述方法在在后续HARQ重传定时器运行的时间内也监测PDCCH。
另外一种可能的方式中，InactivityTimer超时后，终端设备在HARQ重传定时器运行的时间内，不监测PDCCH。也就是说，若终端设备向网络设备发送NACK，则在InactivityTimer超时后且HARQ重传定时器运行的时间内，终端设备停止监测PDCCH，即终端设备在原有onDuration的后续时段不再监测PDCCH，提前进入休眠状态，缩短了持续监测PDCCH的时长。
通过这种方法，可以让终端设备更多的处于休眠状态，从而降低功耗达到省电的 目的。
进一步，网络设备可以通过向终端设备发送第三配置信息，用于为该终端设备配置终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内监测PDCCH(或不监测PDCCH，或是否监测PDCCH)的规则。该第三配置信息可以为与第二配置信息相同的配置信息，或者与第二配置信息不同的配置信息。可选的，该第三配置信息可以为RRC信令。
例如，通过网络设备向终端设备发送第三配置信息，可以指示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内监测PDCCH。若网络设备没有向终端设备发送该第三配置信息，则表示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内不监测PDCCH。
或者，通过网络设备向终端设备发送第三配置信息，可以指示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内不监测PDCCH。若网络设备没有向终端设备发送该第三配置信息，则表示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内监测PDCCH。
或者，通过网络设备向终端设备发送第三配置信息，该第三配置信息取值为1时，可以指示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内不监测PDCCH；该第三配置信息取值为0时，可以指示终端设备在InactivityTimer超时后且HARQ重传定时器运行的时间内监测PDCCH。本申请对第三配置信息的取值规则不做具体限定，以上仅为示例。
在另一种可能的方式中，网络设备可以通过向终端设备发送第三配置信息，用于为该终端设备配置终端设备在HARQ重传定时器运行的时间内监测PDCCH(或不监测PDCCH，或是否监测PDCCH)的规则。此时，第三配置信息配置的终端设备的行为仅与HARQ重传定时器是否运行有关，与InactivityTimer是否运行无关。当第三配置信息配置终端设备在HARQ重传定时器运行的时间内监测PDCCH时，无论InactivityTimer与HARQ重传定时器的运行时间是否重合，终端设备在HARQ重传定时器运行的时间内均监测PDCCH。当第三配置信息配置终端设备在HARQ重传定时器运行的时间内不监测PDCCH时，在InactivityTimer与HARQ重传定时器运行重合的时间内，终端设备受到InactivityTimer的影响监测PDCCH；在InactivityTimer与HARQ重传定时器运行不重合的时间内，终端设备不监测PDCCH。
另一种方实施式中，上述的InactivityTimer也可以是其他的定时器，例如，第一定时器，则终端设备确定在该第一定时器超时的时候或超时之后，并且HARQ重传定时器运行的时间内停止监测PDCCH。本申请对此不做具体限定。
另外，在另一种可能的实施方式中，网络设备可以通过向终端设备发送第三指示信息，用于确定停止监测PDCCH的位置，则终端设备可以根据该第三指示信息确定结束监测PDCCH的位置。
其中，第三指示信息中可以包括第一时刻的时域资源信息，指示终端设备可以在第一时刻停止监测PDCCH。
则终端设备可以根据第三指示信息在第一时刻停止监测PDCCH，具体的，终端设备可以根据第三指示信息，在第一时刻停止运行InactivityTimer和onDurationTimer。
通过本申请的上述实施方式，可以减少数据包传输结束之后，终端设备无效监测PDCCH的时间，降低终端设备的功耗。
此外，如果网络设备为终端设备配置的DRX周期比较短，则本申请还提供一种实施方式，通过网络设备为终端设备发送第四指示信息，使得终端设备可以启动或者重启InactivityTimer，以延长激活时间，监测PDCCH。
在一种实施方式中，网络设备可以向终端设备发送第四指示信息，终端设备可以根据该第四指示信息启动或重启InactivityTimer。
其中，网络设备可以向终端设备发送第四指示信息可以位于onDuration之前，或者onDuration内。如网络设备可以在即将结束PDCCH监测的时刻，即onDuration结束之前的时刻发送第四指示信息。第四指示信息不用于调度数据传输，仅用于指示终端设备可以在结束PDCCH监测后，例如，onDuration的最后一个时隙，启动或重启InactivityTimer。
示例性的，如图14所示，终端设备在onDuration内收到第四指示信息，然后在onDuration之后启动InactivityTimer。
在另一种实施方式中，第四指示信息中还可以包括第一时段的指示，即终端设备可以根据第四指示信息，确定在DRX周期的onDuration之后的第一时段内，监测PDCCH。其中，第一时段可以为网络设备预估的onDuration时段之外数据包传输的时段。具体的，终端设备可以根据第四指示信息，确定在DRX周期的onDuration之后的第一时段内启动或者重启InactivityTimer，从而监测PDCCH。
示例性的，如图15所示，终端设备在onDuration内收到第四指示信息，然后根据第四指示信息在onDuration之后的第一时段内监测PDCCH。
或者，网络设备可以向终端设备发送第四指示信息可以位于onDuration之前，或者onDuration内的开头位置，当网络设备确定该终端设备的数据包不会在该onDuration内进行调度时，可以通过第四指示信息直接指示该终端设备不再监测onDuration，而可以在onDuration之后的第一时段内时间监测PDCCH。
通过上述实施方式，网络设备可以在为终端设备配置的DRX周期比较短的情况下，通过为终端设备发送第四指示信息，使得终端设备可以启动或者重启InactivityTimer，以延长终端设备的激活时间，从而提高监测PDCCH配置的灵活性。
相对应的，在一种实施方式中，网络设备侧可以维护一个或多个终端设备对应的DRX配置信息，例如，网络设备上维护某终端设备的onDuration起始时刻、onDuration时长以及InactivityTimer启动的时刻等。
在上述实施方式中，当网络设备确定该终端设备对应的InactivityTimer超时的时候或者超时之后，网络设备可以停止发送PDCCH，和/或停止网络设备侧维护的该终端设备对应的onDurationTimer。在另一种实施方式中，当网络设备确定该终端设备对应的InactivityTimer超时且HARQ重传定时器在运行时，网络设备可以停止发送PDCCH，和/或停止网络设备侧维护的该终端设备对应的onDurationTimer。此时，当终端设备在DRX周期内onDurationTimer超时前提前进入休眠状态，停止监测PDCCH时，网络设备可以同时停止发送PDCCH，从而使得网络设备侧维护的DRX配置与终端设备侧的DRX配置对齐，提高终端设备节能效率的同时保证网络设备与终端设备 之间的通信效率。
需要说明的是，上述几种实施方式中，第一指示信息、第二指示信息、第三指示信息或者第四指示信息可以承载于下行控制信令(Downlink Control Information，DCI)的至少一个比特位。
