Description

信息监听的方法和装置
本申请要求于2021年09月03日提交中国专利局、申请号为202111029909.6、发明名称为“信息监听的方法和装置”的专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种信息监听的方法和装置。
背景技术
扩展现实(extended reality，XR)和云游戏(cloud gaming，CG)是第五代(5th generation，5G)系统的重要应用场景。XR是不同类型的现实(reality)的总称，指通过计算机或者穿戴设备产生的现实和虚拟结合的环境以及人机交互，XR的类型包括增强现实(augmented reality，AR)、混合现实(mixed reality，MR)，虚拟现实(virtual reality，VR)等。以下行业务传输为例，XR和CG业务数据的传输过程大致为，XR或CG服务器对视频帧进行逻辑计算、内容渲染、编码等处理，再发送给核心网设备，核心网设备将视频帧传输到网络设备，网络设备通过空口传输到用户设备(user equipment,UE)。
XR/CG业务的视频帧到达网络设备的时间是准周期的、具有抖动性，并不是总是有数据传输的，如果接收XR/CG业务的UE长期处于监听物理下行控制信道(physical downlink control channel，PDCCH)的状态，会造成终端设备的功耗过高。
在连接态不连续接收(connected mode discontinuous reception，C-DRX)机制中，UE可以根据DRX的配置信息，在每个DRX周期的激活时间内监听PDCCH，在每个DRX周期的非激活时间内可以处于休眠状态、不监听PDCCH；其中，激活时间包括持续定时器(onDurationTimer)的运行时间，持续定时器的运行时间是周期性出现的。考虑到XR/CG业务在时间上的抖动性，采用C-DRX机制时需配置较长的持续定时器的时长，才能覆盖XR/CG视频帧的抖动；若视频帧延后到达，而UE在onDurationTimer开启时就进行PDCCH盲检，会导致功耗浪费。除此之外，XR/CG业务的周期和DRX周期往往很难匹配，XR/CG的视频帧到达时间可能会落在C-DRX非激活时间内，该情况下网络设备只能等到下一个DRX周期的激活时间进行该视频帧的调度，会导致传输时延增大。
发明内容
本申请提供了一种的信息监听的方法和装置，能够降低终端设备的功耗。
第一方面，提供一种信息监听的方法，该方法可以由终端设备或终端侧的芯片或芯片系统执行。该方法包括：终端设备根据第一搜索空间集组SSSG的搜索空间集确定至少一个第一物理下行控制信道PDCCH候选位置。在不连续接收DRX周期内持续定时器运行期间，所述终端设备在所述第一PDCCH候选位置监听所述第一PDCCH。所述终端设备根据第二SSSG的搜索空间集确定至少一个第二PDCCH候选位置。在所述第一PDCCH上监听到用于调度新传的数据的第一控制信息，所述终端设备在DRX周期内非激活定时 器运行期间，在所述第二PDCCH候选位置监听所述第二PDCCH，所述第一PDCCH的周期大于所述第二PDCCH的周期和/或所述第一SSSG中的搜索空间集的持续时间小于所述第二SSSG中的搜索空间集的持续时间。
基于上述技术方案，在接收到用于调度新传的数据的第一控制信息之前，终端设备根据监听周期较大或者CORESET的带宽较小的第一PDCCH候选位置，监听第一PDCCH，可以降低终端设备的功耗；当接收到用于调度新传的数据的第一控制信息时，终端设备根据监听周期较小或者CORESET的带宽较小的第二PDCCH候选位置，监听第二PDCCH，可以减少数据传输的时延。现有技术中，在持续定时器开始运行时，终端设备可能采用第二SSSG中的搜索空间集监听PDCCH，即采用较小的PDCCH周期监听PDCCH，但是数据到达网络设备的时刻比持续定时器开启时刻晚，导致终端设备根据第二SSSG中的搜索空间集监听PDCCH，带来功耗浪费。相比现有技术，上述技术方案可以避免终端设备在DRX周期内持续定时器运行期间一直采用较小的PDCCH监听周期监听PDCCH，能够降低终端设备的功耗。
在一种实现方式中，所述方法还包括：所述终端设备根据所述第二SSSG的搜索空间集确定至少一个第三PDCCH候选位置。在DRX周期内所述持续定时器运行期间，所述终端设备在所述第三PDCCH候选位置监听所述第三PDCCH，监听所述第一PDCCH的时间与监听所述第三PDCCH的时间不同。终端设备在监听第一PDCCH的时间，根据监听周期较大的第一PDCCH候选位置，监听第一PDCCH，可以降低终端设备的功耗；终端设备在监听第三PDCCH的时间，终端设备根据监听周期较小的第三PDCCH候选位置，监听第三PDCCH，可以减少数据传输的时延。

在一种实现方式中，所述终端设备确定第一参数m和第二参数T，包括：所述终端设备接收来自所述网络设备的第二配置信息，所述第二配置信息中包括所述第一参数m和所述第二参数T。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例可以应用于各种通信系统，例如无线局域网系统(wireless local area network，WLAN)、窄带物联网系统(narrow band-internet of things，NB-IoT)、全球移动通信系统(global system for mobile communications，GSM)、增强型数据速率GSM演进系统(enhanced data rate for gsm evolution，EDGE)、宽带码分多址系统(wideband code division multiple access，WCDMA)、码分多址2000系统(code division multiple access，CDMA2000)、时分同步码分多址系统(time division-synchronization code division multiple access，TD-SCDMA)，长期演进系统(long term evolution，LTE)、卫星通信、第五代(5th generation，5G)系统或者将来出现的新的通信系统等。
适用于本申请的通信系统，包括一个或多个发送端，以及一个或多个接收端。其中，发送端和接收端之间的信号传输，可以是通过无线电波来传输，也可以通过可见光、激光、红外以及光纤等传输媒介来传输。
示例性地，发送端和接收端中的一个可以为终端设备，另一个可以为网络设备。示例性地，发送端和接收端都可以为终端设备。
本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端可以是移动台(mobile station，MS)、用户单元(subscriber unit)、用户设备(user equipment,UE)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端等。
示例性地，网络设备可以是演进型节点B(evolved Node B,eNB)、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(home evolved NodeB,或home Node B,HNB)、基带单元(baseband unit,BBU)，无线保真(wireless fidelity,WIFI)系统中的接入点(access point,AP)、无线中继节点、无线回传节点、传输点(transmission point,TP)或者发送接收点(transmission and reception point，TRP)等，还可以为新空口(new radio,NR)中的gNB或传输点(例如，TRP或TP)，NR中的基站的一个或一组(包括多个)天线面板，或者，还可以为构成gNB或传输点的网络节点，例如基带单元(building baseband unit，BBU)或分布式单元(distributed unit，DU)等，或者，网络设备还可以为车载设备、可穿戴设备以及5G网络中的网络设备，或者未来演进的PLMN网络中的网络设备等，不作限定。
网络设备的产品形态十分丰富。例如，在产品实现过程中，BBU可以与射频单元(Radio  Frequency Unit，RFU)集成在同一设备内，该设备通过线缆(例如但不限于馈线)连接至天线阵列。BBU还可以与RFU分离设置，二者之间通过光纤连接，通过例如但不限于，通用公共射频接口(common public radio interface，CPRI)协议进行通信。在这种情况下，RFU通常称为RRU(remote radio unit，射频拉远单元)，其通过线缆连接至天线阵列。此外，RRU还可以与天线阵列集成在一起，例如，目前市场上的有源天线单元(active antenna unit，AAU)产品就采用了这种结构。
此外，BBU可以进一步分解为多个部分。例如，可以按照所处理业务的实时性将BBU进一步细分为集中单元(centralized unit，CU)和分布单元(distribute unit，DU)。CU负责处理非实时协议和服务，DU负责处理物理层协议和实时服务。更进一步的，部分物理层功能还可以从BBU或者DU中分离出来，集成在AAU中。
扩展现实(extended reality，XR)和云游戏(cloud gaming，CG)是5G的重要应用场景。XR是不同类型的现实(reality)的总称，指通过计算机或者穿戴设备产生的现实和虚拟结合的环境以及人机交互，XR的类型包括增强现实(augmented reality，AR)、混合现实(mixed reality，MR)以及虚拟现实(virtual reality，VR)等。
XR和CG业务以视频帧(video frame)的方式进行传输，其中，视频帧还可以称为画面帧(scene frame)，也可以称为切片(slice)，一个视频帧包含的信息组成一幅画面，帧率(frame per second，FPS)表示每秒生成的视频帧数目，通常，XR和CG业务的帧率可以为30FPS、60FPS、90FPS或120FPS等，例如，60FPS表示每秒生成60个视频帧。
以下行业务传输为例，XR和CG业务数据的传输过程大致为，XR或CG服务器对视频帧进行逻辑计算、内容渲染、编码等处理，再发送给核心网设备，核心网设备将视频帧传输到无线接入网(radio access network，RAN)设备，无线接入网设备再通过空口传输到UE。视频帧的大小不是固定的，不同视频帧的大小是可以变化的。在网络传输过程中，一个视频帧可以被分为一个或多个互联网协议(internet protocol，IP)包(packet)进行传输。根据不同IP包的大小，一个IP包可能会分割为多个传输块(transport block，TB)通过空口传输给UE。通常，一个TB占用一个时隙(slot)或者一个时隙内的几个符号(symbol)，一个TB还可以在多个时隙或者不同符号上重复发送。
XR业务和CG业务的另一个特点为视频帧到达网络设备的时间是准周期的。它的周期为帧率的倒数，即1/FPS，以60FPS为例，则周期为1/60秒，约等于16.67毫秒(ms)。准周期是指在网络设备与UE之间视频帧不是严格按照周期进行传输的，而是有一定时间范围内的波动，这是由于渲染、编码、核心网等因素导致的。
如图1所示，示出了视频帧提前到达网络设备或推迟到达网络设备的示意图。在预期到达(expected arrival)的基础上，不同的视频帧有可能会提前到达网络设备，也可能会推迟到达网络设备。时间上的抖动在统计上服从一定的概率分布，例如，服从均值为0、方差为2的高斯分布，抖动范围为[-4,4]ms，负值表示视频帧提前到达，正值表示视频帧延后到达。
针对XR和CG的应用场景，节省终端设备的功耗是提升用户体验的一个重要方面。由于XR/CG业务是准周期的，并不是总是有数据传输的，如果接收XR/CG业务的终端设备长期处于监听物理下行控制信道(physical downlink control channel，PDCCH)的状态，会造成终端设备的功耗过高。这是因为终端设备需要盲检PDCCH来获取上行数据/下行数 据的调度信息，并根据PDCCH携带的调度信息进行物理下行共享信道(physical downlink shared channel，PDSCH)接收或物理上行共享信道(physical uplink shared channel，PUSCH)发送，如果网络设备不需要进行数据调度，网络设备没有向UE发送PDCCH，那么对于终端设备而言，盲检PDCCH就带来功耗浪费。
为了便于对本申请实施例的理解，简单介绍一下PDCCH的监听机制和已有的降低终端设备功耗的方法。
1、PDCCH的监听机制
PDCCH的作用之一就是用于承载上行的调度信息或下行的调度信息，UE需要周期性的监听PDCCH来获取调度信息，周期可以为1个时隙。如果检测到PDCCH有调度信息，针对下行调度信息，UE可以根据调度信息通过PDSCH接收数据；针对上行调度信息，UE根据调度信息通过PUSCH发送数据。PDCCH还可以用于承载上行功率控制命令字、时隙格式等信息。承载不同控制信息的PDCCH可以采用不同的无线网络临时标识(radio network temporary identifier，RNTI)进行加扰。
一个搜索空间集(search space set，SS set)可以用于定义一组候选PDCCH(PDCCH candidates)，如图2所示，示出了一组候选PDCCH的示意图。网络设备可以为UE配置至少一个搜索空间集(search space set，SS set)。UE基于SS set进行PDCCH监听。例如，UE根据SS set的配置信息，进行PDCCH监听。
示例性的，每个SS set的配置信息可以包括以下至少一项参数：
(1)SS set标识，用于标识SS set；
(2)与该SS set关联的控制资源集(control resource set，CORESET)标识；其中，CORESET表示一个用于承载PDCCH的时频资源集，一个CORESET在频域上由若干个连续的或非连续的资源块(resource block，RB)组成，在时域上由连续的一个或多个符号组成。例如，UE可以根据SS set的参数，例如监听周期、偏移或监听图案等，在该SS set关联的CORESET上进行PDCCH监听。
(3)PDCCH监听周期Ks和偏移Os，取值单位可以为时隙(slot)，Ks>＝1,Os的取值范围为0～Ks-1。
(4)时隙内PDCCH监听图案(pattern)，或者称为时隙内PDCCH监听符号，用于指示该SS set关联的CORESET在时隙内监听PDCCH的起始符号。以14比特位图标识，最高位表示时隙内的第一个OFDM符号，例如，“10000000000000”表示时隙内的第一个OFDM符号为时隙内监听PDCCH的起始符号，监听PDCCH的符号长度由该SS set关联的CORESET的符号长度确定。
(5)持续时间Ts，用于指示该SS set出现的连续的时隙的个数。其中，Ts小于或等于Ks，Ts的取值可以为1个时隙。例如，可理解为在PDCCH监听周期Ks内连续监听PDCCH的时隙的个数，例如，Ts＝2表示在PDCCH监听周期内连续两个slot监听PDCCH。
(6)聚合等级以及各聚合等级对应的候选PDCCH(PDCCH candidate)的个数。
(7)SS set类型指示，用于指示该SS set是公共搜索空间集(common search space set，CSS set)，可以简称为CSS，或者是用户专用搜索空间集(UE-specific search space set，USS set)，可以简称为USS。其中，若该SS set的类型为CSS，网络设备还会配置在PDCCH候选位置监听的下行控制信息(downlink control information，DCI)格式(format)，例如， 可以为DCI格式0_0、DCI格式1_0、DCI格式2_0、DCI格式2_1、DCI格式2_2、DCI格式2_3、DCI格式2_4、DCI格式2_5或DCI格式2_6等。若该SS set的类型为USS，则网络设备也会配置在PDCCH候选位置监听的DCI格式，例如，可以为DCI格式0_0、DCI格式1_0、DCI格式0_1、DCI格式1_1、DCI格式0_2、DCI格式1_2、DCI格式3_0、或DCI格式3_1等。
UE可以根据上述参数中的PDCCH监听周期、偏移，以及时隙内PDCCH监听图案等，确定PDCCH监听时机(monitoring occasion，MO)/PDCCH候选位置，如图2所示。在本申请中，UE监听PDCCH是指UE在PDCCH候选位置监听PDCCH。
2、连接态不连续接收(connected mode discontinuous reception，C-DRX)机制
C-DRX表示连接态下的DRX机制，因此在连接态下也可以简写为DRX。在C-DRX机制中，终端设备可以根据网络设备配置的DRX周期(DRX cycle)，周期性打开接收机监听PDCCH，如图3所示，示出了一个C-DRX周期的示意图。在一个DRX周期中通常包含两个时间段：激活时间(active time)和非激活时间(non-active time)。终端设备在active time内在PDCCH监听时机进行PDCCH监听，而在non-active time内可以处于休眠状态，不监听PDCCH，从而节省终端功耗。
需要说明的是，C-DRX机制主要用于控制以下RNTI加扰的PDCCH：小区无线网络临时标识(cell-RNTI，C-RNTI)，取消指示RNTI(cancellation indication-RNTI，CI-RNTI)，配置调度RNTI(configured scheduling-RNTI，CS-RNTI)，中断RNTI(interruption-RNTI，INT-RNTI)，时隙格式指示RNTI(slot format indication-RNTI，SFI-RNTI)，半持续信道状态信息RNTI(semi-persistent-channel state information-RNTI，SP-CSI-RNTI)，物理上行控制信道发送功率控制RNTI(transmit power control-physical uplink control channel-RNTI，TPC-PUCCH-RNTI)，物理上行共享信道发送功率控制RNTI(transmit power control-PUSCH-RNTI，TPC-PUSCH-RNTI)，探测参考信道发送功控控制RNTI(transmit power control-sounding reference signal-RNTI，TPC-SRS-RNTI)和可用性指示RNTI(availability indication-RNTI，AI-RNTI)，即在非激活时间，UE不监听上述RNTI加扰的PDCCH。对于系统消息RNTI(system information-RNTI，SI-RNTI)，随机接入RNTI(random access-RNTI，RA-RNTI),消息B RNTI(message B-RNTI，MsgB-RNTI),临时小区RNTI(temporary cell-RNTI，TC-RNTI)加扰的PDCCH不受C-DRX机制约束。
激活时间至少包括持续定时器(drx-onDurationTimer)运行的时间。网络设备可以通过无线资源控制(radio resource control，RRC)信令向终端设备配置drx-onDurationTimer的长度。
DRX周期可以包括长不连续接收周期(Long DRX cycle)和短不连续接收周期(short DRX cycle)，其中short DRX cycle为可选的配置。后文中如果没有特别说明，DRX cycle可以是Long DRX cycle或者short DRX cycle。以长不连续接收周期(Long DRX cycle)为例，网络设备还会配置Long DRX cycle长度的参数drx-LongCycle和用于确定DRX周期开始的子帧的参数drx-StartOffset，以及DRX周期开始的子帧内开启drx-onDurationTimer之前的时间偏移量的参数drx-SlotOffset。如果使用Long DRX cycle，当子帧号(subframe number)满足如下公式(1)，终端开启drx-onDurationTimer(后文简写为onDurationTimer)：
[(SFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset   (1)
其中，SFN为系统帧号，modulo表示取模运算。系统帧也可以称作无线帧，一个无线帧为10ms，一个无线帧可由多个子帧(subframe)组成，每个子帧由一个或多个时隙组成。即在Long DRX cycle的起始子帧延迟drx-SlotOffset之后开启onDurationTimer，如图4所示，示出了开启onDurationTimer与drx-SlotOffset和drx-StartOffset的关系的示意图。
如果使用短不连续接收周期(short DRX cycle)，当子帧号(subframe number)满足如下公式(2)，终端设备开启drx-onDurationTimer：
[(SFN×10)+子帧号]modulo(drx-ShortCycle)＝(drx-StartOffset)modulo(drx-ShortCycle)(2)即在short DRX cycle的起始子帧延迟drx-SlotOffset之后开启onDurationTimer。
根据上述描述可知，当网络设备配置了C-DRX参数以后，终端设备周期性打开onDurationTimer的时间位置也就固定了，不能实时动态的调整onDurationTimer的时间位置。
可选的，在C-DRX机制中，激活时间还可以包括：不连续接收-非激活定时器(drx-InactivityTimer)、不连续接收-下行链路(downlink，DL)重传定时器(drx-RetransmissionTimerDL)、以及不连续接收-上行链路(uplink，UL)重传定时器(drx-RetransmisionTimerUL)运行的时间。后面drx-InactivityTimer简称InactivityTimer，drx-RetransmissionTimerDL简称RetransmissionTimerDL，drx-RetransmisionTimerUL简称RetransmisionTimerUL。网络设备通过RRC信令向终端设备配置的C-DRX参数具体可以如表1所示。开启drx-InactivityTimer、drx-RetransmissionTimerDL以及drx-RetransmisionTimerUL的触发条件见表1中所描述，即有数据传输时，这三个定时器才会启动。

激活时间还可以包括：随机接入-冲突解决定时器(ra-ContentionResolutionTimer)或者消息B-响应窗(msgB-response window)运行期间；UE在PUCCH上发送了调度请求(scheduling request，SR)之后的等待(pending)期间；UE在成功接收到基于非竞争的随机接入的随机接入响应(random access response，RAR)之后还未收到指示新传的PDCCH期间。
3、搜索空间集组(search space set group，SSSG)切换机制
网络设备可以为一个带宽部分(bandwidth part，BWP)配置多个SS set，可以将这些SS set进行分组，具体的可以分为两组(group)或者更多组。例如，以SS set分为两组SSSG为例，在SS set的配置信息中可以配置该SS set属于第一个组，例如SSSG0，还是属于第二个组，例如SSSG1。也可以允许一个SS set属于多个SSSG，即既属于SSSG0，又属于SSSG1。对于配置有SSSG索引的SS set，UE只需要根据其中一个SSSG的SS set监听PDCCH。如上文所述，可以通过SS set的配置信息，每个SSSG实现不同稀疏程度的PDCCH监听时机。
如图5所示，示出了两组不同SSSG的示意图。不同SSSG关联的SS set可以有不同的PDCCH监听时机(候选位置)，当UE切换到的SSSG中PDCCH监听时机较稀疏时，例如，图5中的SSSG 0，UE根据属于SSSG 0的SS set监听PDCCH，而不需要根据属于SSSG 1的SS set监听PDCCH，由于属于SSSG 0的SS set的PDCCH监听时机比较稀疏，则可以达到节省功耗的目的。
网络设备和UE可以动态切换SSSG，可以通过DCI中比特域显式指示或者DCI隐式指示SSSG切换。以两组SSSG为例，两组SSSG分别为SSSG 0和SSSG 1为例。DCI中的比特域显式指示可以包括：当DCI中的比特域指示为“0”时，UE切换到SSSG 0，即根据SSSG 0的SS set监听PDCCH，停止根据SSSG 1的SS set监听PDCCH；当该域指示为“1”，UE切换到SSSG 1，即根据SSSG1的SS set监听PDCCH。反之亦然。DCI隐式指示可以包括：如果UE正在根据PDCCH监听时机稀疏的SSSG中的SS set监听PDCCH，当UE检测到任意DCI格式(format)，或者检测到特定的DCI format，则UE从PDCCH监听时机稀疏的SSSG切换到PDCCH监听时机的密集的SSSG。UE还可以经过一段时长自动切换SSSG，例如，UE根据属于SSSG 0的SS set监听PDCCH，经过一段时长以后，UE切换到SSSG 1，反之亦然。一段时长可以通过定时器实现，例如，UE根据属于SSSG 0的SS set监听PDCCH的同时启动一个定时器，当定时器超时时，UE根据属于SSSG 1的SS set监听PDCCH。
XR/CG业务有低时延、高可靠的需求，同时，考虑到XR/CG业务在时间上的抖动性，采用C-DRX机制，需要配置较长的onDurationTimer运行的时间，才能覆盖XR/CG视频帧的抖动。以60FPS为例，需要配置DRX cycle＝16ms，考虑到抖动范围为[-4,4]ms，onDurationTimer运行的时间长度需要设置为8ms。如图6所示，示出了视频帧延后到达的示意图。由于视频帧延后到达，而UE在持续定时器(onDurationTimer)开启时就需要进行PDCCH盲检，因此，会带来功耗浪费。
XR/CG业务的周期为帧率的倒数，XR/CG业务的周期通常为非整数，例如，帧率为60FPS，对应的周期约为16.67ms；帧率为120FPS对应的周期约为8.33ms。由于DRX周期通常为整数，不考虑时间上的抖动，XR/CG业务的周期也很难和DRX周期匹配。如图7所示，示出了网络设备根据DRX周期发送视频帧的示意图。以60FPS为例，假设onDurationTimer＝4ms，则6个DRX cycle以后，XR/CG的视频帧到达时间则会落在DRX非激活时间内，网络设备只能等到下一个DRX cycle的激活时间进行调度，增加了时延，如果时延太大，还可能导致丢包，从而影响用户体验。此外，不同的XR/CG设备可能支持不同的帧率，针对每一种的帧率引入一种新的DRX周期长度，这种方法不够灵活。
作为一种可实施的方式，根据onDurationTimer的时间长度，将DRX cycle划分为几个不重叠的图案(pattern)，即有N种pattern，其中，N满足如下公式(3)，如果不能整除，可以向上或者向下取整。。假设DRX cycle为16ms，onDurationTimer＝4ms，则有4个pattern，即有4种drx-StartOffset；网络设备可以通过DCI指示后续的DRX cycle采用哪个pattern。如图8所示，示出了将DRX cycle划分为4个不重叠的pattern的示意图。
Figure PCTCN2022113491-appb-000003
采用其中一种pattern时，例如pattern1，会出现在onDurationTimer即将结束时才有IP包的情况，例如图7中虚线框的部分，此时由于网络设备调度器等原因，网络设备可能来不及在当前的onDurationTimer内发送DCI进行调度，那么只能到下一个DRX cycle的onDurationTimer才能进行调度。由于不同pattern的onDurationTimer运行起始时间不重叠，即使切换到另一个pattern，IP包仍可能落在onDurationTimer之外。
本申请实施例提出了信息监听的方法，能够节省终端设备的功耗。
如图9所示，出示了本申请实施例提出的一种信息监听的方法900的示意性流程交互图。
网络设备可以配置C-DRX参数、搜索空间集SS set的配置信息以及SS set的分组信息。其中，C-DRX参数可以理解为DRX的配置信息。本申请实施例中的网络设备可以为基站。C-DRX参数包括表1中的参数。

示例性的，所述控制信息可以为DCI，用于调度PDSCH或PUSCH承载的数据。应理解，网络设备确定DRX周期内持续定时器的运行时间的步骤(即920)与确定至少一个第一PDCCH候选位置的步骤(即910)是可以不分先后顺序的。
930，终端设备根据第一SSSG的搜索空间集确定至少一个第一PDCCH候选位置。其中，属于第一SSSG的搜索空间集可能有一个或多个。
940，终端设备根据C-DRX参数，确定DRX周期内持续定时器的运行时间。在所述DRX周期内持续定时器运行期间，所述终端设备在所述第一PDCCH候选位置监听第一PDCCH。
其中，所述第一PDCCH可用于承载第一控制信息。应理解，终端设备确定DRX周 期内持续定时器的运行时间的步骤与确定至少一个第一PDCCH候选位置的步骤是可以不分先后顺序的。
应理解，910和920是可以不分先后顺序的，930和940也是可以不分先后顺序的。除此之外，930和940可以在910之前，或者，910、920与930、940可以是同时进行的。本申请实施例对此不做限定。
需要特别说明的是，步骤920与步骤940中，确定DRX周期内持续定时器的运行时间的方法可以通过前述介绍的公式(1)或公式(2)确定。
950，网络设备根据第二SSSG的搜索空间集确定至少一个第二PDCCH候选位置。
960，当第一控制信息用于调度新传的数据时，该网络设备开启非激活定时器，在非激活定时器运行期间，该网络设备在第二PDCCH候选位置向终端设备发送至少一个第二控制信息。
应理解，第一控制信息可以是用于调度新传的数据的控制信息，也可以是用于调度重传的数据的控制信息，还可以用于指示非调度数据的控制信息，例如组公共DCI。应理解，网络设备开启非激活定时器与确定至少一个第二PDCCH候选位置的步骤是可以不分先后顺序的。
在910之前，网络设备还向终端设备配置搜索空间集SS set的配置信息以及SS set的分组信息，即SSSG。SS set的配置信息可以参考前文，在SS set的配置信息中还可以配置SSSG的索引用于指示该SS set所属的SSSG，在本实施例中配置SS set的配置信息时，第一SSSG的SS set和第二SSSG的SS set至少满足以下一项：
第一SSSG的搜索空间集的PDCCH周期大于第二SSSG的搜索空间集的PDCCH周期。PDCCH周期越大，在一段时间内，需要监听的PDCCH候选位置越少；或者，
第一SSSG中的搜索空间集的持续时间(SS set duration)小于第二SSSG中的搜索空间集的持续时间，其中，搜索空间集的持续时间可以理解为搜索空间集的每个PDCCH监听周期内连续监听PDCCH的时隙的个数；或者，
第一SSSG的搜索空间集关联的CORESET的带宽小于第二SSSG的搜索空间集关联的CORESET的带宽；或者，
第一SSSG的搜索空间集的PDCCH候选的个数小于第二SSSG的搜索空间集的PDCCH候选的个数。具体地，可表示为第一SSSG的搜索空间集中聚合等级种类小于第一SSSG的搜索空间集中聚合等级种类，或者，同一聚合等级下，属于第一SSSG的搜索空间集中聚合等级对应的PDCCH候选的个数小于属于第二SSSG的搜索空间集中聚合等级对应的PDCCH候选的个数，或者，由第一SSSG的搜索空间集确定的PDCCH候选位置上PDCCH候选的个数小于由第二SSSG的搜索空间集确定的PDCCH候选位置上PDCCH候选的个数；或者
第一SSSG的搜索空间集的时隙内PDCCH监听图案少于第二SSSG的搜索空间集的时隙内PDCCH监听图案。例如，第一SSSG的搜索空间集的时隙内PDCCH监听图案只位于时隙起始符号，第二SSSG的搜索空间集的时隙内PDCCH监听图案可以位于时隙中的任意符号，即第一SSSG的搜索空间集的PDCCH候选起始位置位于时隙起始符号，而第二SSSG的搜索空间集的PDCCH候选起始位置在时隙内有多个且位于不同的符号。
可选的，第一SSSG的搜索空间集可以是第二SSSG的搜索空间集的子集。
非激活定时器开启的起始时间是根据用于调度新传的数据的第一控制信息的发送时间确定的。因此，非激活定时器的运行时间与持续定时器的运行时间可以是部分重叠的，即可以同时运行两个定时器；非激活定时器的运行时间与持续定时器的运行时间也可以是不重叠的。
970，终端设备根据第二SSSG的搜索空间集确定至少一个第二PDCCH候选位置。其中，属于第二SSSG的SS set可以有一个或多个。
980，当终端设备在第一PDCCH上监听到用于调度新传的数据的第一控制信息时，该终端设备在非激活定时器运行期间，在第二PDCCH候选位置监听第二PDCCH，即该终端设备在第二PDCCH候选位置检测至少一个第二控制信息。
具体地，当终端设备在第一PDCCH上监听到用于调度新传的数据的第一控制信息时，则终端设备开启非激活定时器，在非激活定时器运行期间，在第二PDCCH候选位置监听第二PDCCH。应理解，终端设备开启非激活定时器与确定至少一个第二PDCCH候选位置的步骤是可以不分先后顺序的。
应理解，网络设备中950和960与终端设备中970和980是可以不分先后顺序的。
在本申请实施例提供的技术方案中，在DRX周期内持续定时器开始运行时，终端设备根据属于第一SSSG的搜索空间集的至少一个第一PDCCH候选位置监听第一PDCCH，当接收到用于调度新传的第一控制信息时，开启非激活定时器，并在非激活定时器运行期间，该终端设备根据属于第二SSSG的搜索空间集的至少一个第二PDCCH候选位置监听第二PDCCH。在接收到用于调度新传的数据的第一控制信息之前，终端设备根据监听周期较大或者CORESET的带宽较小的第一PDCCH候选位置监听第一PDCCH，可以降低终端设备的功耗；当接收到用于调度新传的数据的第一控制信息时，终端设备根据监听周期较小或者CORESET的带宽较小的第二PDCCH候选位置监听第二PDCCH，可以减少数据传输的时延。现有技术中，在持续定时器开始运行时，终端设备可能采用第二SSSG中的搜索空间集监听PDCCH，即采用较小的PDCCH周期监听PDCCH，但是数据到达网络设备的时刻比持续定时器开启时刻晚，导致终端设备根据第二SSSG中的搜索空间集监听PDCCH，带来功耗浪费。因此，相比现有技术，本申请提供的技术方案可以避免终端设备在DRX周期内持续定时器运行期间一直采用较小的PDCCH监听周期监听PDCCH，能够降低终端设备的功耗。当终端设备监听到调度数据的控制信息，可以认为网络设备有数据需要传输，则UE采用较小的PDCCH监听周期监听PDCCH，可以尽快完成数据传输。
可选的，网络设备可以根据第二SSSG的搜索空间集确定至少一个第三PDCCH候选位置。在DRX周期内持续定时器运行期间，该网络设备可以在第三PDCCH候选位置向终端设备发送第三控制信息。其中，发送第三控制信息的时间与发送第一控制信息的时间不同。应理解，在DRX周期内持续定时器运行期间，采用第二SSSG的搜索空间集监听PDCCH的时间范围和采用第一SSSG的搜索空间集监听PDCCH的时间范围不同。
对应地，终端设备可以根据第二SSSG的搜索空间集确定至少一个第三PDCCH候选位置；在DRX周期内持续定时器运行期间，该终端设备在第三PDCCH候选位置监听第三PDCCH，即该终端设备在第三PDCCH候选位置检测至少一个第三控制信息。其中，终端设备监听第一PDCCH的时间与监听第三PDCCH的时间不同。应理解，终端设备根 据第一PDCCH候选位置监听第一PDCCH的时间范围与根据第三PDCCH候选位置监听第三PDCCH的时间范围不同，即，在DRX周期内持续定时器运行期间，终端设备采用第二SSSG的时间范围与采用第一SSSG的时间范围不同。
监听第一PDCCH的时间可以称之为第一时间段，即根据第一SSSG的SS set监听第一PDCCH的时间段，监听第三PDCCH的时间可以称之为第三时间段，即根据第二SSSG的SS set监听第三PDCCH的时间段。DRX周期内持续定时器运行期间包括第一时间段和第三时间段，第一时间段和第三时间段为不同的时间段。终端设备在第一时间段内根据第一SSSG的SS set监听第一PDCCH，在第三时间段内根据第二SSSG的SS set监听第三PDCCH。XR/CG的数据传输在时间上的抖动服从一定的概率分布，其中，第一时间段可以为没有数据传输或数据传输较少的时间段，第三时间段可以为有数据传输或数据传输较多的时间段；例如，第一时间段可以为XR/CG业务数据没有到达的时间段，第三时间段可以为XR/CG业务数据到达的时间段。
第一时间段与第三时间段可以是预定义的，也可以是网络设备向终端设备配置的。换言之，第一时间段的起始时间和/或时间长度、第三时间段的起始时间和/或时间长度可以是预定义的，也可以是网络设备配置的。
示例性的，网络设备向终端设备发送第一配置信息，该第一配置信息中包括以下至少一种：监听第一PDCCH的起始时间、监听第一PDCCH的时间长度、监听第三PDCCH的起始时间、或监听第三PDCCH的时间长度。应理解，监听第一PDCCH的起始时间、监听第一PDCCH的时间长度、监听第三PDCCH的起始时间、监听第三PDCCH的时间长度分别为第一时间段的起始时间、第一时间段的时间长度、第三时间段的起始时间、第三时间段的时间长度。终端设备可以接收来自网络设备的第一配置信息。该第一配置信息可以包括在C-DRX参数中，也可以单独配置。该第一配置信息可以是网络设备通过RRC信令发送的，也可以是网络设备在前一个DRX周期内发送的DCI或者PDSCH承载的MAC CE指示的。
其中，监听第一PDCCH的起始时间与DRX周期内持续定时器开启的起始时间、DRX cycle的起始时间或DRX cycle开始的子帧之间的偏移记为第一偏移值(offset)，该第一偏移值可以等于0，可以是网络设备配置的，也可以是协议预定义的。还可以直接预定义监听第一PDCCH的起始时间与DRX周期内持续定时器开启的起始时间相同。
监听第一PDCCH的时间长度或监听第三PDCCH的时间长度可以和持续定时器长度或者DRX周期的大小有关，具体地，监听第一PDCCH的时间长度可以表示为delta1*onDurationTimer，其中0≤delta1≤1；或者，监听第一PDCCH的时间长度也可以表示为delta2*DRX cycle，其中delta2≥0。同理，监听第三PDCCH的时间长度可以表示为delta3*onDurationTimer，其中0≤delta3≤1；或者，监听第三PDCCH的时间长度也可以表示为delta4*DRX cycle，其中delta4≥0。监听第一PDCCH的时间长度不超过持续定时器运行的时间，例如，监听第一PDCCH的时间长度可以等于持续定时器运行的时间。
示例性地，监听第一PDCCH的时间长度和监听第三PDCCH的时间长度可以是预定义的。终端设备接收的第一配置信息中可以只包括监听第一PDCCH的起始时间，由于监听第一PDCCH的时间长度是预定义的，则可以确定监听第一PDCCH的时间，持续定时器运行期间除监听第一PDCCH的时间之外的时间可以确定为监听第三PDCCH的时间。 终端设备接收的第一配置信息中可以只包括监听第三PDCCH的起始时间，持续定时器运行期间除监听第三PDCCH的时间之外的时间可以确定为监听第一PDCCH的时间。终端设备接收的第一配置信息中也可以包括监听第一PDCCH的起始时间和监听第三PDCCH的起始时间。
示例性地，可以预定义监听第一PDCCH的起始时间与DRX周期内持续定时器开启的起始时间相同，终端设备接收的第一配置信息中可以只包括监听第一PDCCH的时间长度，持续定时器运行期间除监听第一PDCCH的时间之外的时间可以确定为监听第三PDCCH的时间。终端设备接收的第一配置信息中可以包括监听第一PDCCH的时间长度和监听第三PDCCH的时间长度，监听第三PDCCH的起始时间可以是监听第一PDCCH的结束时间。
如图10所示，出示了在持续定时器运行期间在第一时间段和第三时间段分别根据不同的SSSG监听不同PDCCH的示意图。在T1时间段(第一时间段)内，终端设备在属于第一SSSG的搜索空间集的第一PDCCH候选位置，处于低功耗状态；在T2时间段(第三时间段)内，终端设备在属于第二SSSG的搜索空间集的第三PDCCH候选位置，处于高功耗状态。
可选的，第一时间段也可以为非连续的，第三时间段也可以为非连续的。如图11所示，出示了另一种在持续定时器运行期间在第一时间段和第三时间段分别根据不同的SSSG监听不同PDCCH的示意图。第一时间段包括非连续的时间段T1和T3，在T1和T3时间段内，终端设备在属于第一SSSG的搜索空间集的第一PDCCH候选位置，处于低功耗状态；在T2时间段(第三时间段)内，终端设备在属于第二SSSG的搜索空间集的第三PDCCH候选位置，处于高功耗状态。
可选的，网络设备也可以给终端设备配置多个第一时间段，网络设备可以通过媒体接入控制控制元素(Medium Access Control control element，MAC CE)或者DCI指示采用哪个第一时间段。如表2所示，出示了网络设备向终端设备配置的多个第一时间段。
表2
根据第一SSSG的搜索空间集监听第一PDCCH的时间段
T1_1
T1_2
T1_3，T3_1
T1_4，T3_2
可选的，网络设备还可以向终端设备配置或者指示比特位图，比特位图中的每一个比特对应一个时间单元，用于表示该时间单元内根据第一SSSG的搜索空间集监听第一PDCCH或者根据第二SSSG的搜索空间集监听第三PDCCH。
基于上述方案，在DRX周期内持续定时器运行期间，第一时间段可能为没有数据传输或数据传输较少的时间段，在该第一时间段内，终端设备在属于第一SSSG的搜索空间集的第一PDCCH候选位置监听第一PDCCH；第三时间段可以为有数据传输或数据传输较多的时间段，在该第三时间段内，终端设备在属于第二SSSG的搜索空间集的第三PDCCH候选位置监听第三PDCCH。可以避免在没有业务传输或业务传输较少时终端设备一直根据监听周期较小或者CORESET的带宽较小的PDCCH候选位置监听PDCCH，从 而可以降低终端设备的功耗。
为了进一步降低终端设备的功耗，网络设备还可以给终端设备配置或者指示最小调度偏移值(minimum scheduling offset)，最小调度偏移值可以包括K0min和/或K2min。K0min用于约束PDCCH承载的DCI调度PDSCH时，PDCCH与PDSCH之间的时间偏移值，即PDCCH与PDSCH之间的时间偏移值不小于K0min，K2min用于约束PDCCH承载的DCI调度PUSCH时，PDCCH与PUSCH之间的时间偏移值，即PDCCH与PUSCH之间的时间偏移值不小于K2min。其中，时间偏移值可以为时隙偏移值，最小调度偏移值可以为最小调度时隙偏移值。
可选的，第一SSSG和第二SSSG分别关联一个最小调度偏移值，例如，网络设备向终端设备配置或指示第一SSSG关联的第一最小调度偏移值，第二SSSG关联的第二最小调度偏移值。终端设备在第一PDCCH候选位置监听第一PDCCH时，第一调度偏移值大于或等于第一阈值，第一调度偏移值是第一PDCCH与第一PDCCH调度的物理下行共享信道PDSCH或物理上行共享信道PUSCH之间的时间偏移值，其中第一阈值可以理解为第一最小调度偏移值。终端设备在第二PDCCH候选位置监听第二PDCCH时，第二调度偏移值大于或等于第二阈值，第二调度偏移值是第二PDCCH与第二PDCCH调度的PDSCH或PUSCH之间的时间偏移值，其中，第一阈值大于第二阈值，第二阈值可以理解为第二最小调度偏移值。终端设备在第三PDCCH候选位置监听第三PDCCH时，第三调度偏移值大于或等于第二阈值，第三调度偏移值是第三PDCCH与第三PDCCH调度的PDSCH或PUSCH之间的时间偏移值。示例性地，第一阈值大于0，第二阈值等于0。当第一阈值大于0，终端设备在监听PDCCH时无需缓存PDCCH所在时隙中可能存在的PDSCH，终端设备还可以放松PDCCH处理时间，即终端设备可以降低时钟频率和电压，从而达到降低终端设备功耗的效果。
可选的，非激活定时器运行期间也不一定总是有数据传输，因此，也可以参照前面的方法，网络设备向终端设备配置或指示在非激活定时器运行期间根据第一SSSG的SS set监听PDCCH的时间段，终端设备在该时间段内根据监听周期较大或者CORESET带宽较小的搜索空间集监听PDCCH，可以降低终端设备的功耗。
可选的，如果终端设备检测到下行DCI，则在发送HARQ反馈之后开启对应HARQ进程的HARQ-RTT-TimerDL。如果HARQ-RTT-TimerDL到期，并且该HARQ进程的PDSCH没有译码正确，则UE在HARQ-RTT-TimerDL到期之后开启对应HARQ进程的RetransmissionTimerDL，并在RetransmissionTimerDL内继续根据第一SSSG或者第二SSSG的搜索空间集监听PDCCH。可选的，可以参照前面的方法，网络设备向终端设备配置或指示在HARQ-RTT-TimerDL内根据第一SSSG的SS set监听PDCCH的时间段，终端设备在该时间段内根据监听周期较大或者CORESET带宽较小的搜索空间集监听PDCCH，可以降低终端设备的功耗。
可选的，如果UE检测到上行DCI，则在该DCI调度的PUSCH上发送传输块(或者，在PUSCH上重复发送传输块时第一次发送该传输块)之后打开该HARQ进程的HARQ-RTT-TimerUL。如果HARQ-RTT-TimerUL到期，则在HARQ-RTT-TimerUL到期之后开启对应进程的RetransmissionTimerUL，并在RetransmissionTimerUL内继续根据第一SSSG的搜索空间集或者第二SSSG的搜索空间集监听PDCCH。可选的，可以参照前 面的方法，网络设备向终端设备配置或指示在HARQ-RTT-TimerUL内根据第一SSSG的SS set监听PDCCH的时间段，终端设备在该时间段内根据监听周期较大或者CORESET带宽较小的搜索空间集监听PDCCH，可以降低终端设备的功耗。
在多载波场景下，主小区(primary cell，PCell)和各个辅小区(secondary cell，SCell)可以分别配置有第一SSSG和第二SSSG，可以按照上述方法分别确定在onDurationTimer运行期间在各个小区中用于监听PDCCH的SSSG，可选的，当UE在Pcell根据第一SSSG的SS set监听PDCCH时，UE在激活的Scell根据第一SSSG的SS set监听PDCCH。为了进一步降低终端功耗，还可以规定，在辅小区上配置第一SSSG为不监听PDCCH的SSSG，例如，辅小区的第一SSSG中不包含任一SS set，没有PDCCH监听时机，当UE在Pcell根据属于第一SSSG的SS set监听PDCCH时，UE在激活的Scell停止监听PDCCH，或者UE在激活的Scell上切换到所述第一SSSG。
由于XR/CG业务的周期与DRX周期不匹配，导致XR/CG的视频帧到达时间可能会落在DRX非激活时间内，网络设备只能等到下一个DRX cycle的激活时间进行调度，增加了数据传输的时延，影响用户体验。为此，本申请实施例还提出了动态调整DRX周期的起始时间和/或DRX周期内持续定时器开启的起始时间，避免需要传输的数据的到达时间落在DRX非激活时间内，以降低数据传输的时延。
在一种实现方式中，网络设备还可以根据C-DRX参数，确定第i个DRX周期的起始时间和/或第i个DRX周期内持续定时器开启的起始时间，i为正整数。网络设备确定第一参数m和第二参数T，m为正整数。该第一参数m可以是周期性调整DRX周期的起始时间所间隔的DRX周期的个数，该第一参数m也可以是周期性调整DRX周期内持续定时器的起始时间所间隔的DRX周期的个数，第一参数还可以是周期性调整DRX周期的起始时间和DRX周期内持续定时器的起始时间所间隔的DRX周期的个数。该第二参数T可以是调整DRX周期的起始时间的偏移值和/或调整DRX周期内持续定时器开启的起始时间的偏移值。该网络设备根据C-DRX参数、第一参数m和第二参数T，确定第i+m个DRX周期的起始时间和/或所述第i+m个DRX周期内持续定时器开启的起始时间。
对于第i+1个～第i+m-1个DRX周期，网络设备同样根据C-DRX参数确定DRX周期的起始时间和DRX周期内持续定时器开启的起始时间。
对于第i+m+1个～第i+2*m-1个DRX周期，网络设备根据C-DRX参数、第一参数m和第二参数T确定DRX周期的起始时间和/或DRX周期内持续定时器开启的起始时间。以此类推，网络设备根据C-DRX参数、第一参数m和第二参数T确定第i+n*m个～第i+(n+1)*m-1个DRX周期的起始时间和/或持续定时器开启的起始时间。
应理解，DRX周期的起始时间与DRX周期内持续定时器开启的起始时间可以是相同的，也可以是不同的。
对应地，终端设备根据获取的C-DRX参数，确定第i个DRX周期的起始时间和/或第i个DRX周期内持续定时器开启的起始时间，i为正整数。该终端设备确定第一参数m和第二参数T。示例性地，第一参数m和第二参数T可以是网络设备确定并发送给终端设备的。具体地，网络设备可以向终端设备发送第二配置信息，该第二配置信息中包括第一参数m和第二参数T；终端设备可以接收来自网络设备的第二配置信息。第一参数m和第二参数T可以承载在同一配置信息中，也可以承载在不同配置信息中。应理解，该第 二配置信息与上述第一配置信息可以承载在同一配置信息中，也可以承载在不同配置信息中。第一参数m和第二参数T也可以是预定义的。终端设备根据C-DRX参数、第一参数m和第二参数T，确定第i+m个DRX周期的起始时间和/或第i+m个DRX周期内持续定时器开启的起始时间。
对于第i+1个～第i+m-1个DRX周期，终端设备同样根据C-DRX参数确定DRX周期的起始时间和DRX周期内持续定时器开启的起始时间。可理解，终端设备未调整DRX周期的起始时间和DRX周期内持续定时器开启的起始时间。
对于第i+m+1个～第i+2*m-1个DRX周期，终端设备根据C-DRX参数、第一参数m和第二参数T确定DRX周期的起始时间和/或DRX周期内持续定时器开启的起始时间。其中，第i+m个～第i+2*m-1个DRX周期认为是一次调整。以此类推，终端设备根据C-DRX参数、第一参数m和第二参数T确定第i+n*m个～第i+(n+1)*m-1个DRX周期的起始时间和/或持续定时器开启的起始时间。第i+n*m个～第i+(n+1)*m-1个DRX周期认为是一次调整。
可选的，第一参数m与DRX周期的大小和数据传输周期的大小相关。示例性地，该第一参数m可以是根据DRX周期的大小和XR/CG业务数据的传输周期的大小确定的，例如，假设XR/CG业务数据的传输周期减去DRX周期的大小的差值为delta，第一参数m可以根据delta确定，例如，第一参数m满足m*delta最接近onDurationTimer并且小于或等于onDurationTimer，或者，(m+1)*delta最接近onDurationTimer并且小于或等于onDurationTimer，或者，(m-1)*delta最接近onDurationTimer并且小于或等于onDurationTimer。
可选的，第二参数T可以与DRX周期调整的次数相关。示例性地，T可以等于n*offset1，其中，n为自第i个DRX周期开始DRX周期调整的次数，offset1可以为网络设备配置的或预定义的偏移值，例如，offset1为XR/CG业务数据的传输周期减去DRX周期的大小的差值。该第二参数T可以与DRX周期的大小和数据传输周期的大小相关，示例性地，该第二参数T可以是根据DRX周期的大小和XR/CG业务数据的传输周期的大小确定的，例如，T为XR/CG业务数据的传输周期减去DRX周期的大小的差值。该第二参数T还可以与DRX周期调整的次数以及DRX周期的大小和数据传输周期的大小相关。
如图12所示，示出了一种调整第i+m个DRX周期内持续定时器开启的起始时间的示意图。在调整第i+m个DRX周期内持续定时器开启的起始时间时，第i+m个DRX周期的起始时间有两种方式，一种是如图12中方式1，第i+m个DRX周期的起始时间与原始的第i+m个DRX周期的起始时间相同，即第i+m个DRX周期的起始时间不做调整，仍按照现有的C-DRX参数确定，与第一参数m和第二参数T无关；另一种是如图12中方式2，第i+m个DRX周期的起始时间与第i+m个DRX周期内持续定时器开启的起始时间相同，可以理解为，同时调整第i+m个DRX周期内持续定时器开启的起始时间和第i+m个DRX周期的起始时间。应理解，持续定时器开启的起始时间可以是起始子帧或起始时隙。
可选的，调整后的第i+m个DRX周期内持续定时器开启的起始时间在原始的的第i+m个DRX周期内持续定时器运行的时间段内。原始的DRX周期起始时间和持续定时器的运行时间根据按照现有的C-DRX参数确定。如图12中所示，调整后的第i+m个DRX周期 内持续定时器开启的起始时间不超过虚线对应的时间范围，虚线对应的时间范围为根据现有的C-DRX参数确定的第i+m个DRX周期内持续定时器运行时间。
在另一种实现方式中，网络设备确定第一指示信息，该第一指示信息可以用于指示下一个DRX周期的持续定时器开启的起始时间和/或下一个DRX周期的持续定时器开启的起始时间偏移值。该网络设备在DRX周期的激活时间中，向终端设备发送至少一个控制信息和/或至少一个数据，该控制信息和/或数据中包括该第一指示信息。该起始时间偏移值可以是drx-StartOffset和drx-SlotOffset以外的偏移值，或者是参数drx-StartOffset的偏移量或drx-SlotOffset的的偏移量。
可选的，该第一指示信息也可以用于指示下一个DRX周期的起始时间和/或下一个DRX周期的起始时间偏移值。
具体地，以下至少一种信息中可以包括该第一指示信息：第一控制信息、第二控制信息、第三控制信息、第一控制信息调度的PDSCH承载的MAC CE、第二控制信息调度的PDSCH承载的MAC CE、第三控制信息调度的PDSCH承载的MAC CE。
相应地，终端设备获取第一指示信息。具体地，终端设备在DRX周期的激活时间内，监听至少一个PDCCH和/或在至少一个PDSCH上接收数据，该至少一个PDCCH承载的控制信息和/或该数据中包括第一指示信息；终端设备根据接收到的第一指示信息，确定下一个DRX周期内持续定时器开启的起始时间或下一个DRX周期的起始时间。其中，至少一个PDCCH包括上述第一PDCCH、第二PDCCH或第三PDCCH，至少一个PDSCH包括上述第一控制信息调度的PDSCH、上述第二控制信息调度的PDSCH或上述第三控制信息调度的PDSCH。其中，第一指示信息包括在PDSCH的数据中，可以是指包含第一第一指示信息的MAC CE承载在PDSCH中。

[(SFN×10)+subframe number]modulo(drx-LongCycle)＝drx-StartOffset+offset2(4)
或者，根据公式(1)确定的子帧偏移drx-SlotOffset+offset2之后开启下一个DRX的持续定时器。
如图13所示，示出了一种调整下一个DRX周期内持续定时器开启的起始时间的示意图。图13中，虚线双箭头对应的持续定时器运行时间为不引入第一指示信息指示的起始时间偏移值时下一DRX周期内持续定时器运行的时间，实线双箭头对应的持续定时器运行时间为根据第一指示信息指示的起始时间偏移值调整后的下一DRX周期内持续定时器运行的时间。持续定时器开启的起始时间偏移值可以是在上一个DRX周期的激活时间内网络设备通过PDSCH发送的第一指示信息指示的。

可选的，第一参数m与DRX周期的大小和数据传输周期的大小相关。示例性地，该第一参数m可以是根据DRX周期的大小和XR/CG业务数据的传输周期的大小确定的，例如，假设XR/CG业务数据的传输周期减去DRX周期的大小的差值为delta，第一参数m根据delta确定，例如，第一参数m满足m*delta最接近onDurationTimer并且小于或等于onDurationTimer，或者，(m+1)*delta最接近onDurationTimer并且小于或等于onDurationTimer，或者，(m-1)*delta最接近onDurationTimer并且小于或等于onDurationTimer。
示例性的，第二参数T可以与DRX周期调整的次数相关。示例性地，T可以等于n*offset1，其中，n为DRX周期调整的次数，offset1可以为网络设备配置的或预定义的偏移值，例如，offset1为XR/CG业务数据的传输周期减去DRX周期的大小的差值。该第二参数T可以与DRX周期的大小和数据传输周期的大小相关。示例性地，该第二参数T可以是根据DRX周期的大小和XR/CG业务数据的传输周期的大小确定的，例如，T为XR/CG业务数据的传输周期减去DRX周期的大小的差值。该第二参数T还可以与DRX周期调整的次数以及DRX周期的大小和数据传输周期的大小相关。
示例性地，该第一参数m第二参数T可以是网络设备确定的，也可以是预定义的。当该第一参数m第二参数T是网络设备确定的时，该网络设备可以向终端设备发送第二配置信息，该第二配置信息中包括第一参数m和第二参数T。应理解，该第二配置信息与上述第一配置信息可以承载在同一配置信息中，也可以承载在不同配置信息中；换言之，该第一配置信息与上述第二配置信息可以为相同的配置信息。

1460，终端设备根据C-DRX参数、第一参数m和第二参数T，确定第i+m个DRX周期的起始时间和/或第i+m个DRX周期内持续定时器开启的起始时间。
对于第i+1个～第i+m-1个DRX周期，终端设备同样根据C-DRX参数确定DRX周期的起始时间和DRX周期内持续定时器开启的起始时间。可理解，终端设备未调整DRX周期的起始时间和DRX周期内持续定时器开启的起始时间。
对于第i+m+1个～第i+2*m-1个DRX周期，终端设备根据C-DRX参数、第一参数m和第二参数T确定DRX周期的起始时间和/或DRX周期内持续定时器开启的起始时间。其中，第i+m个～第i+2*m-1个DRX周期认为是一次调整。以此类推，终端设备根据C-DRX参数、第一参数m和第二参数T确定第i+n*m个～第i+(n+1)*m-1个DRX周期的起始时间和/或持续定时器开启的起始时间。
应理解，1410和1440可以是同时进行的，1420和1450可以是同时进行的，1430和1460也可以是同时进行的。
示例性的，如果C-DRX参数中包括多个drx-StartOffset，或者，根据公式(4)确定了多个图案，即同一个DRX周期的起始时间和/或同一个DRX周期内的持续定时器的起始时间可以有多个，网络设备可以通过PDCCH指示更新1410和1440中的C-DRX参数中的drx-StartOffset或者指示更新图案，则网络设备和终端设备重新执行上述步骤。
