Description

监测周期的调整方法及装置
本申请要求于2019年08月26日提交国家知识产权局、申请号为201910792872.9、申请名称为“监测周期的调整方法及装置”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，尤其涉及监测周期的调整方法及装置。
背景技术
相比于长期演进(long term evolution，LTE)系统，第五代(5th generation，5G)新空口(new radio，NR)系统需要支持更大的带宽和更高的传输速率，因此NR终端的功耗比LTE终端的功耗更大。终端的功耗的增大会导致终端的待机时间的减少，从而影响到用户体验。因此，5G网络需要采用相应的降低终端功耗的优化方案。
发明内容
本申请提供一种监测周期的调整方法及装置，用于降低终端的功耗。
第一方面，提供一种监测周期的调整方法，包括：终端接收来自网络设备的第一指示信息，第一指示信息用于指示终端在调度时间间隔最小值发生变化时是否调整下行控制信道的监测周期，调度时间间隔最小值为下行控制信道所在的时隙与下行控制信道对应的数据信道所在的时隙之间的时隙差的最小值；之后，终端根据第一指示信息，确定是否调整下行控制信道的监测周期。
基于上述技术方案，终端根据第一指示信息，确定在调度时间间隔最小值发生变化时是否调整下行控制信道的监测周期。需要说明的是，终端根据调度时间间隔最小值，调整下行控制信道的监测周期，可以降低终端的功耗。终端不调整下行控制信道的监测周期，可以避免增加数据的传输时延。可见，网络设备通过第一指示信息，灵活地指示终端调整/不调整下行控制信道的监测周期，以达到兼顾数据传输时延和终端功耗的目的。
一种可能的设计中，该方法还包括：终端接收来自网络设备的第二指示信息，第二指示信息用于指示调度时间间隔最小值。当终端根据第一指示信息，确定调整下行控制信道的监测周期时，该方法还包括：终端根据第一调度时间间隔最小值，调整下行控制信道的监测周期。这样一来，下行控制信道的监测周期可以匹配第一调度时间间隔最小值，使得终端可以在较长的时间内保持睡眠状态，以降低终端功耗。
一种可能的设计中，第一指示信息和第二指示信息承载于同一下行控制信息中。

具体实施方式
在本申请的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种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。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释 为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请的描述中，“指示”可以包括直接指示和间接指示，也可以包括显式指示和隐式指示。将某一信息(如下文所述的能力指示信息)所指示的信息称为待指示信息，则具体实现过程中，对所述待指示信息进行指示的方式有很多种。例如，可以直接指示所述待指示信息，其中所述待指示信息本身或者所述待指示信息的索引等。又例如，也可以通过指示其他信息来间接指示所述待指示信息，其中该其他信息与所述待指示信息之间存在关联关系。又例如，还可以仅仅指示所述待指示信息的一部分，而所述待指示信息的其他部分则是已知的或者提前约定的。另外，还可以借助预先约定(例如协议规定)的各个信息的排列顺序来实现对特定信息的指示，从而在一定程度上降低指示开销。
为了便于理解本申请的技术方案，下面先对本申请所涉及的术语进行简单介绍。
1、物理下行控制信道(physical downlink control channel，PDCCH)
PDCCH用于承载调度以及其他控制信息，例如下行控制信息(downlink control information，DCI)。PDCCH由控制信道单元(control channel element，CCE)构成。
2、下行控制信息(downlink control information，DCI)
DCI可以包括诸如资源块(resource block，RB)分配信息、调制方式(modulation and coding scheme，MCS)等内容。不同DCI所携带的信息是不一样的，功能也是不一样的。为了对DCI进行分类，协议中定义了多种DCI格式(format)。
例如，当前通信标准定义了如下DCI format：
DCI format0-0：用于调度终端上行数据；
DCI format1-0：用于调度终端下行数据；
DCI format2-0：用于指示时隙格式；
DCI format2-1：用于指示中断传输(interrupted transmission)；
以上仅是对DCI format的示例，在此不一一展开叙述。
3、下行时域资源分配
在下行数据传输的过程中，终端需要根据物理下行共享信道(physical downlink shared channel，PDSCH)的时域位置信息，确定PDSCH的时域位置，以便于接收PDSCH。
其中，PDSCH的时域位置信息包括以下参数：
(1)时隙偏移值K 0。终端可以根据K 0和PDCCH所在的时隙，确定PDSCH所在的时隙。
例如，如果终端在时隙n接收到PDCCH，则该PDCCH所调度的PDSCH在时隙
Figure PCTCN2020108018-appb-000001
中传输，其中μ PDSCH为PDSCH的子载波间隔配置信息，μ PDCCH为PDCCH的子载波间隔配置信息。
其中，K 0也可以有其他名称，例如下行调度时间间隔，本申请实施例不限于此。
(2)起始和长度指示值(start and length indicator value，SLIV)。SLIV用于指示PDSCH在时隙中的起始正交频分复用(orthogonal frequency division multiplexing，OFDM)符号的索引值S，以及PDSCH的时域长度L。可以理解的是，PDSCH的时域长度即为PDSCH从起始OFDM符合起开始占用的连续OFDM符号的个数。
其中，SLIV由S和L联合编码得到。SLIV可以根据以下公式确定：
如果(L-1)≤7，那么SLIV＝14×(L-1)+S；
否则，SLIV＝14×(14-L+1)+(14-1-S)，其中0<L≤14-S。
(3)PDSCH的映射类型。其中，PDSCH的映射类型包括：类型(type)A和type B。对于不同的PDSCH的映射类型，S、L、以及S+L的取值范围是不同的，用于支持不同类型的时域调度。
示例性的，表1示出不同PDSCH的映射类型下，S、L、以及S+L的取值范围。
表1
Figure PCTCN2020108018-appb-000002
需要说明的是，终端配置有时域资源分配(time domain resource allocation，TDRA)表格。该TDRA表格可以是标准中预定义的，也可以是网络设备以RRC信令的方式发送给终端的。
其中，TDRA表格包括4列，第一列为索引值(index)，第二列为索引值对应的K 0，第三列为索引值对应的SLIV，第四列为索引值对应的PDSCH的映射类型。
示例性的，TDRA表格可以如表2所示。
表2
Index K 0 SLIV PDSCH的映射类型
0 0 66 typeA
1 1 27 typeB
…… …… …… ……
在下行数据传输之前，网络设备会向终端发送用于调度下行数据的PDCCH，PDCCH指示一个index。从而，终端根据TDRA表格，以及PDCCH所指示的index，可以确定PDSCH的时域位置信息。
4、上行时域资源分配
在上行数据传输过程中，终端需要根据物理上行共享信道(physical uplink shared channel，PUSCH)的时域位置信息，确定PUSCH的时域位置，以便于终端在PUSCH的时域位置上发送PUSCH。
其中，PUSCH的时域位置信息包括以下参数：
(1)时隙偏移值K 2。终端可以根据K 2和PDCCH所在的时隙，确定PUSCH所在的时隙。
例如，如果终端在时隙n接收到PDCCH，则该PDCCH所调度的PUSCH在时隙
Figure PCTCN2020108018-appb-000003
中传输，其中μ PUSCH为PUSCH的子载波间隔配置信息，μ PDCCH为PDCCH的子载波间隔配置信息。
其中，K 2也可以有其他名称，例如上行调度时间间隔，本申请实施例不限于此。
(2)SLIV。SLIV的具体描述可参见上文，在此不再赘述。
(3)PUSCH的映射类型。其中，PUSCH的映射类型包括：type A和type B。对于不同的PUSCH的映射类型，S、L、以及S+L的取值范围是不同的，用于支持不同类型的时域调度。
示例性的，表3示出不同PUSCH的映射类型下，S、L、以及S+L的取值范围。
表3
Figure PCTCN2020108018-appb-000004
需要说明的是，终端配置有TDRA表格。该TDRA表格可以是标准中预定义的，也可以是网络设备以RRC信令的方式发送给终端的。
其中，TDRA表格包括4列，第一列为索引值(index)，第二列为索引值对应的K 2，第三列为索引值对应的SLIV，第四列为索引值对应的PUSCH的映射类型。
示例性的，TDRA表格可以如表4所示。
表4
Index K 2 SLIV PUSCH的映射类型
0 2 27 typeB
1 2 91 typeB
…… …… …… ……
在上行数据传输之前，网络设备会向终端发送用于调度上行数据的PDCCH，PDCCH指示一个index。从而，终端根据TDRA表格，以及PDCCH所指示的index，可以确定PUSCH的时域位置信息。
5、跨时隙调度、同时隙调度
跨时隙调度和同时隙调度是两种不同的数据调度方式。
若数据调度方式为跨时隙调度，则下行控制信道与下行控制信道所调度的数据信道不在同一个时隙中传输。
若数据调度方式为同时隙调度，则下行控制信道与下行控制信道所调度的数据信道在同一个时隙中传输。
6、搜索空间
搜索空间为候选PDCCH的集合。搜索空间可以分为：公共搜索空间(common search space)和UE特定的搜索空间(UE-specific search space)。公共搜索空间用于传输寻呼(Paging)消息、系统信息等相关的控制信息。UE特定的搜索空间用于与下行共享信道(downlink shared channel，DL-SCH)、上行共享信道(uplink shared channel，UL-SCH)等相关的控制信息。当然，公共搜索空间也可以用于传输属于某个特定UE的控制信息，本申请实施例对此不作任何限制。
可以理解的是，网络设备可以为终端配置一个或多个搜索空间，网络设备也可以删除之前为终端所配置的搜索空间。
可选的，对于一个搜索空间来说，搜索空间的配置参数可以包括：监测周期、监测偏移值，本申请实施例不限于此。其中，监测周期和监测偏移值的粒度均为时隙。监测偏移 值用于确定终端在监测周期内的第几个时隙开始监测搜索空间。例如，若监测周期包含4个时隙，监测偏移值为2，则表示终端在监测周期的第三个时隙开始监测搜索空间。
7、功耗节省信号(power saving signal)
功耗节省信号用于指示功耗节省信息。功耗节省信号可以用来实现降低终端的功耗的目的。
可选的，功耗节省信号位于非连续接收(discontinuous reception)DRX周期的休眠期(On Duration)之前，用于指示终端在与该功耗节省信号关联的DRX周期的On Duration中处于睡眠状态或正常工作状态。可选的，可以在功耗节省信号中使用比特信息的形式指示终端在与该功耗节省信号关联的DRX周期的On Duration中处于睡眠状态或正常工作状态。例如，在功耗节省信号中使用1个比特进行指示，该比特为‘0’时，表示终端将处于睡眠状态，该比特为‘1’时，表示终端将处于正常工作状态。此外，功耗节省信号还可以用于指示其他功能，例如指示终端跳过PDCCH监测(skipping PDCCH monitoring)，指示终端切换BWP(bandwidth part，带宽部分)，指示辅小区激活或去激活，触发信道状态测量等等。
可选的，功耗节省信号也可以位于DRX周期的激活期(Active Time)内，或者用于未被配置DRX的情况下。此时功耗节省信号至少可以用于指示跨时隙调度的相关参数。
可选的，功耗节省信号可以基于PDCCH实现，或者说，功耗节省信号可以基于DCI实现。需要说明的是，在功耗节省信号基于DCI实现的情况下，功耗节省信号可以以特定的DCI format来表示。
以上是对本申请所涉及的技术术语的介绍，下文中不再赘述。
本申请实施例提供的技术方案可以应用于各种通信系统，例如，采用5G通信技术的NR通信系统，未来演进系统或者多种通信融合系统等等。本申请提供的技术方案可以应用于多种应用场景，例如，机器对机器(machine to machine，M2M)、宏微通信、增强型移动互联网(enhanced mobile broadband，eMBB)、超高可靠超低时延通信(ultra-reliable&low latency communication，uRLLC)以及海量物联网通信(massive machine type communication，mMTC)等场景。这些场景可以包括但不限于：终端与终端之间的通信场景，网络设备与网络设备之间的通信场景，网络设备与终端之间的通信场景等。下文中均是以应用于网络设备和终端之间的通信场景中为例进行说明的。
此外，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
图1示出了本申请提供的技术方案所适用的一种通信系统的架构示意图，通信系统可以包括一个或多个网络设备(图1中仅示出了1个)以及一个或多个终端(图1中仅示出了一个)。
网络设备可以是无线通信的基站或基站控制器等。例如，所述基站可以包括各种类型的基站，例如：微基站(也称为小站)，宏基站，中继站，接入点等，本申请实施例对此不作具体限定。在本申请实施例中，所述基站可以是全球移动通信系统(global system for mobile communication，GSM)，码分多址(code division multiple access，CDMA)中的基 站(base transceiver station，BTS)，宽带码分多址(wideband code division multiple access，WCDMA)中的基站(node B)，长期演进(long term evolution，LTE)中的演进型基站(evolutional node B，eNB或e-NodeB)，物联网(internet of things，IoT)或者窄带物联网(narrow band-internet of things，NB-IoT)中的eNB，未来5G移动通信网络或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，本申请实施例对此不作任何限制。本申请实施例中，用于实现网络设备的功能的装置可以是网络设备，也可以是能够支持网络设备实现该功能的装置，例如芯片系统。在本申请实施例中，以用于实现网络设备的功能的装置是网络设备为例，描述本申请实施例提供的技术方案。
本申请所说的网络设备，例如基站，通常包括基带单元(baseband unit，BBU)、射频拉远单元(remote radio unit，RRU)、天线、以及用于连接RRU和天线的馈线。其中，BBU用于负责信号调制。RRU用于负责射频处理。天线用于负责线缆上导行波和空气中空间波之间的转换。一方面，分布式基站大大缩短了RRU和天线之间馈线的长度，可以减少信号损耗，也可以降低馈线的成本。另一方面，RRU加天线比较小，可以随地安装，让网络规划更加灵活。除了RRU拉远之外，还可以把BBU全部都集中起来放置在中心机房(central office，CO)，通过这种集中化的方式，可以极大减少基站机房数量，减少配套设备，特别是空调的能耗，可以减少大量的碳排放。此外，分散的BBU集中起来变成BBU基带池之后，可以统一管理和调度，资源调配更加灵活。这种模式下，所有的实体基站演变成了虚拟基站。所有的虚拟基站在BBU基带池中共享用户的数据收发、信道质量等信息，相互协作，使得联合调度得以实现。
在一些部署中，基站可以包括集中式单元(centralized unit，CU)和分布式单元(Distributed Unit，DU)。基站还可以包括有源天线单元(active antenna unit，AAU)。CU实现基站的部分功能，DU实现基站的部分功能。比如，CU负责处理非实时协议和服务，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)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PDCP层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，CU可以划分为RAN中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，在此不做限制。
终端是一种具有无线收发功能的设备。终端可以被部署在陆地上，包括室内或室外、手持或车载；也可以被部署在水面上(如轮船等)；还可以被部署在空中(例如飞机、气球和卫星上等)。终端设备可以是用户设备(user equipment，UE)。其中，UE包括具有无线通信功能的手持式设备、车辆、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart  home)中的无线终端等等。本申请实施例中，用于实现终端的功能的装置可以是终端，也可以是能够支持终端实现该功能的装置，例如芯片系统。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例中，以用于实现终端的功能的装置是终端为例，描述本申请实施例提供的技术方案。

当前，在终端接收PDCCH时，终端无法确定数据调度方式是同时隙调度还是跨时隙调度。因此，终端在解码PDCCH的过程中会缓存下行信号，以避免未接收到下行信号而导致同时隙调度的数据丢失。示例性的，这种情况下，终端的功耗可以参考图3所示。
若终端能够提前预知数据调度方式为跨时隙调度，则终端在解码PDCCH的过程中可以关闭射频模块，不缓存任何信号。示例性的，这种情况下，终端的功耗可以参考图4所示。
结合图3和图4可以获知，对于跨时隙调度，终端能够提前预知数据调度方式是跨时隙调度，有利于降低终端的功耗。基于此，网络设备可以向终端指示一个调度时间间隔最小值，以使得终端获知数据调度方式是否是跨时隙调度。具体的，若调度时间间隔最小值为0，则说明数据调度方式可能不是跨时隙调度，从而终端在解码PDCCH的过程中需要缓存下行信号。若调度时间间隔最小值大于0，则说明数据调度方式一定是跨时隙调度，从而终端在解码PDCCH的过程中可以关闭射频模块。
目前，现有技术中未定义调度时间间隔最小值与下行控制信道的监测周期之间的关系。因此，一种简单的实现方式为：调度时间间隔最小值与下行控制信道的监测周期之间不存在任何关系。也即，终端和网络设备不会根据调度时间间隔最小值，调整下行控制信道的监测周期。基于这种实现方式，在下行控制信道的监测周期小于调度时间间隔最小值的情况下，终端关闭射频模块的时长(也即睡眠时长)小于调度时间间隔最小值对应的时长，导致终端的睡眠时长较短，不能很好地降低终端的功耗。结合图5(a)进行举例说明，假设K 0最小值为2，下行控制信道的监测周期为1。在终端从时隙#1中接收到下行控制信道之后，终端在时隙#1的解码PDCCH的过程中关闭射频模块，以节约功耗。但是，在时隙#2中，终端由于需要再次监测PDCCH，因此终端需要重新打开射频模块，导致终端关闭射频模块的时长小于K 0最小值对应的时长(也即2个时隙)。
为了解决这一技术问题，本申请实施例提供一种监测周期的调整方法，其技术原理在于：终端和网络设备根据调度时间间隔最小值，调整下行控制信道的监测周期，以使得下行控制信道的监测周期匹配调度时间间隔最小值(也即下行控制信道的监测周期大于等于调度时间间隔最小值)。
结合图5(b)进行举例说明，假设K 0最小值为2，下行控制信道的监测周期从1调整为2。这样一来，在终端从时隙#1中接收到下行控制信道之后，终端在时隙#1的解码PDCCH的过程中关闭射频模块，以节约功耗。并且，由于终端无需在时隙#2中监测下行控制信道，因此终端还可以在时隙#2中继续关闭射频模块，以降低终端的功耗。
基于本申请的技术方案，终端在接收到下行控制信道之后，终端在一定时长内(也即调度时间间隔最小值对应的时长)内不用进行不必要的监测操作，从而避免终端频繁的进行“睡眠/唤醒”的切换，有利于节省终端功耗。
在本申请实施例中，终端进入“睡眠”状态是指终端关闭射频模块，终端进入“唤醒”状态，是指终端打开射频模块。可以理解的是，若终端的射频模块被关闭，有利 于降低终端的功耗。
需要说明的是，网络设备/终端在调度时间间隔最小值发生改变的情况下，是否需要调整下行控制信道的监测周期，可以由标准中定义，或者是网络设备确定的，或者是网络设备和终端协商确定的。例如，网络设备可以向终端发送第一指示信息，以指示终端在调度时间间隔最小值发生改变的情况下，是否调整下行控制信道的监测周期。又例如，网络设备可以向终端发送第三指示信息，以指示终端在调度时间间隔最小值发生改变的情况下，需要调整下行控制信道的监测周期。
如图6所示，为本申请实施例提供的一种监测周期的调整方法，该方法应用于通信装置，该通信装置为终端或者网络设备。该监测周期的调整方法包括以下步骤：
S101、通信装置确定调度时间间隔最小值。
其中，调度时间间隔最小值为下行控制信道所在的时隙与下行控制信道调度的数据信道所在的时隙之间的时隙差的最小值。
示例性的，下行控制信道可以为PDCCH。数据信道可以为PDSCH或者PUSCH。本申请实施例不限于此。
在本申请实施例中，调度时间间隔最小值包括下行调度时间间隔最小值或者上行调度时间间隔最小值。可以理解的是，在下行控制信道所调度的数据信道为下行数据信道(例如PDSCH)的情况下，调度时间间隔最小值为下行调度时间间隔最小值。在下行控制信道所调度的数据信道为上行数据信道(例如PUSCH)的情况下，调度时间间隔最小值为上行调度时间间隔最小值。
可选的，下行调度时间间隔可以记为K 0，因此下行调度时间间隔最小值可以记为K 0最小值，或者K 0的最小可使用值(minimum application value)。上行调度时间间隔可以记为K 2，因此上行调度时间间隔最小值可以记为K 2最小值，或者K 2的最小可使用值。
作为一种实现方式，在通信装置为网络设备的情况下，网络设备可以根据终端所支持的调度时间间隔最小值，确定调度时间间隔最小值。或者，网络设备可以终端的业务类型，确定调度时间间隔最小值。
作为另一种实现方式，在通信装置为终端的情况下，终端根据网络设备所发送的第二指示信息，确定调度时间间隔最小值。
S102、通信装置根据调度时间间隔最小值，调整下行控制信道的监测周期。
作为一种实现方式，通信装置根据下行调度时间间隔最小值，调整下行控制信道的监测周期。或者，通信装置根据上行调度时间间隔最小值，调整下行控制信道的监测周期。
在本申请实施例中，下行控制信道的监测周期是否调整，可以由下行调度时间间隔最小值和/或上行调度时间间隔最小值是否发生改变来决定。
例如，在终端的下行调度时间间隔最小值发生改变的情况下，通信装置可以根据改变后的下行调度时间间隔最小值，来调整下行控制信道的监测周期。在终端的上行调度时间间隔最小值发生改变的情况下，通信装置不调整下行控制信道的监测周期。
又例如，在终端的上行调度时间间隔最小值发生改变的情况下，通信装置可以根据改变后的上行调度时间间隔最小值，来调整下行控制信道的监测周期。在终端的下行调度时间间隔最小值发生改变的情况下，通信装置不调整下行控制信道的监测周期。
又例如，在终端的上行调度时间间隔最小值/下行调度时间间隔最小值发生改变的情况下，通信装置可以根据改变后的上行调度时间间隔最小值/下行调度时间间隔最小值，来调整下行控制信道的监测周期。
需要说明的是，终端监测下行控制信道实际上是通过监测搜索空间来实现的。因此，调整下行控制信道的监测周期可以通过调整搜索空间的监测周期或者调整需要监测的搜索空间来实现。
在本申请实施例中，终端和网络设备会根据同一个调度时间间隔最小值，来调整下行控制信道的监测周期。这样一来，保证终端和网络设备采用相同的下行控制信道的监测周期，以使得终端可以监测到网络设备所发送的下行控制信道，保证终端和网络设备之间的正常通信。
可选的，网络设备可以向终端指示调度时间间隔最小值，以此触发终端根据该调度时间间隔最小值，调整下行控制信道的监测周期。并且，网络设备也会根据该调度时间间隔最小值，调整下行控制信道的监测周期。
可选的，终端可以根据调度时间间隔最小值，调整下行控制信道的监测周期。之后，终端向网络设备发送指示信息，以指示网络设备根据调度时间间隔最小值，调整下行控制信道的监测周期。
下面针对通信装置的不同情况，来具体说明通信装置如何调整下行控制信道的监测周期。
(1)在通信装置为终端的情况下，终端调整下行控制信道的监测周期，可以包括以下实现方式：
实现方式一、对于配置给终端的多个搜索空间中的每一个搜索空间来说，在调度时间间隔最小值为0的情况下，终端将搜索空间的监测周期设置为1；在调度时间间隔最小值不为0的情况下，终端将搜索空间的监测周期设置为调度时间间隔最小值。
基于实现方式一，搜索空间的监测偏移值根据公式offset＝a％(N)确定。其中，offset表示搜索空间的监测偏移值，a表示第二指示信息所在的时隙的索引值，％表示取模运算或者取余运算，N表示搜索空间的监测周期。
可以理解的是，相比较于现有技术中搜索空间的配置参数(例如监测周期)不可更改，本申请实施例中，终端通过改变搜索空间的监测周期，来改变下行控制信道的监测周期，从而使得下行控制信道的监测周期可以匹配调度时间间隔最小值。这样一来，基于实现方式一，配置给终端的多个搜索空间具有相同的监测周期和监测偏移值，从而终端可以在同一时间段内监测多个搜索空间，避免终端频繁的进行“睡眠/唤醒”的切换，达到降低终端功耗的目的。另外，在调度时间间隔最小值不为0的情况下，配置给终端的多个搜索空间的监测周期等于调度时间间隔最小值。这样一来，终端在从一个搜索空间接收到下行控制信道之后，在调度时间间隔最小值对应的时长内，终端无需再次监测搜索空间，从而终端可以关闭射频模块，以降低终端的功耗。
实现方式二、终端在第一搜索空间中监测下行控制信道，不在第二搜索空间中监测下行控制信道。也就是说，第一搜索空间可以用于承载下行控制信道。第二搜索空间不可以用于承载下行控制信道。
一种可能的设计中，第一搜索空间和第二搜索空间均是网络设备预先配置给终端的 搜索空间。第一搜索空间的监测周期大于等于调度时间间隔最小值。第二搜索空间的监测周期小于调度时间间隔最小值。
结合图7(a)和图7(b)进行举例说明。如图7(a)所示，网络设备为终端配置了三个搜索空间。其中，搜索空间#1的监测周期为1个时隙，搜索空间#2的监测周期为2个时隙，搜索空间#3的监测周期为4个时隙。如图7(b)所示，从时隙#5开始，调度时间间隔最小值从0变为2，则在时隙#5之后的时隙中，终端仅需监测搜索空间#2和搜索空间#3，终端无需监测搜索空间#1。
可以理解的是，相比较于现有技术中终端需要监测每一个配置给终端的搜索空间，本申请实施例中，终端通过选择监测一部分搜索空间(也即第一搜索空间)，不监测另一部分搜索空间(也即第二搜索空间)，以改变终端监测下行控制信道的周期。并且，由于第一搜索空间的监测周期大于等于调度时间间隔最小值，因此终端仅监测第一搜索空间，可以保证下行控制信道的监测时间能够与调度时间间隔最小值匹配。从而，终端在从一个搜索空间接收到下行控制信道之后，在调度时间间隔最小值对应的时长内，终端无需再次监测搜索空间，以使得终端可以关闭射频模块，以降低功耗。
实现方式三、终端在与调度时间间隔最小值的对应的一组搜索空间中监测下行控制信道。可以理解的是，一组搜索空间包含一个或多个搜索空间。
需要说明的是，网络设备可以预先为终端配置了多组搜索空间，每一组搜索空间与一个调度时间间隔最小值对应。
可选的，对于一组搜索空间中的每一个搜索空间来说，搜索空间的监测周期可以等于对应的调度时间间隔最小值。
举例来说，网络设备为终端配置了三组搜索空间，第一组搜索空间对应的调度时间间隔最小值为3，第二组搜索空间对应的调度时间间隔最小值为4，第三组搜索空间对应的调度时间间隔最小值为5。在网络设备向终端指示调度时间间隔最小值为4的情况下，终端在第二组搜索空间中监测下行控制信道，不在第一组搜索空间和第三组搜索空间中监测下行控制信道。
可以理解的是，相比较于现有技术中终端需要监测每一个配置给终端的搜索空间，本申请实施例中，终端通过监测一部分搜索空间(也即与调度时间间隔最小值对应的一组搜索空间)，不监测另一部分搜索空间(也即不与调度时间间隔最小值对应的其他组搜索空间)，以改变终端监测下行控制信道的周期。并且，由于终端需要监测的一组搜索空间与调度时间间隔最小值对应，因此可以保证下行控制信道的监测时间能够与调度时间间隔最小值匹配。从而，终端在从一个搜索空间接收到下行控制信道之后，在调度时间间隔最小值对应的时长内，终端无需再次监测搜索空间，以使得终端可以关闭射频模块，以降低功耗。
以上实现方式一至实现方式三仅是下行控制信道的监测周期的调整方式的示例，本申请实施例不限于此。
(2)在通信装置为网络设备的情况下，网络设备调整下行控制信道的监测周期，可以包括以下实现方式：
实现方式一、对于配置给终端的多个搜索空间中的每一个搜索空间来说，在调度时间间隔最小值为0的情况下，网络设备将搜索空间的监测周期设置为1；在调度时 间间隔最小值不为0的情况下，网络设备将搜索空间的监测周期设置为调度时间间隔最小值。
基于实现方式一，搜索空间的监测偏移值根据公式offset＝a％(N)确定。其中，offset表示搜索空间的监测偏移值，a表示第二指示信息所在的时隙的索引值，％表示取模运算或者取余运算，N表示搜索空间的监测周期。
可以理解的是，相比较于现有技术中搜索空间的配置参数(例如监测周期不可更改)，本申请实施例中，网络设备通过更改搜索空间的监测周期，以使得下行控制信道的监测周期可以匹配调度时间间隔最小值。具体的，在在调度时间间隔最小值不为0的情况下，配置给终端的多个搜索空间的监测周期等于调度时间间隔最小值。从而，网络设备在一个搜索空间中发送下行控制信道之后，在调度时间间隔最小值对应的时长内，网络设备不会再次发送下行控制信道，从而终端也无需监测搜索空间，以使得终端可以关闭射频模块，达到降低功耗的目的。
实现方式二、网络设备在第一搜索空间中发送下行控制信道，不在第二搜索空间中发送下行控制信道。也就是说，第一搜索空间可以用于承载下行控制信道。第二搜索空间不可以用于承载下行控制信道。
一种可能的设计中，第一搜索空间和第二搜索空间均是网络设备预先配置给终端的搜索空间。第一搜索空间的监测周期大于等于调度时间间隔最小值。第二搜索空间的监测周期小于调度时间间隔最小值。
结合图7(a)和图7(b)进行举例说明。如图7(a)所示，网络设备为终端配置了三个搜索空间。其中，搜索空间#1的监测周期为1个时隙，搜索空间#2的监测周期为2个时隙，搜索空间#3的监测周期为4个时隙。如图7(b)所示，从时隙#5开始，调度时间间隔最小值从0变为2，则在时隙#5之后的时隙中，网络设备仅以搜索空间#2和搜索空间#3承载下行控制信道，不以搜索空间#1承载下行控制信道。
可以理解的是，相比较于现有技术中网络设备可以在每一个配置给终端的搜索空间中发送下行控制信道，本申请实施例中，网络设备通过选择在一部分搜索空间(也即第一搜索空间)中发送下行控制信道，不在另一部搜索空间(也即第二搜索空间)中发送下行控制信道，从而使得终端可以不用监测全部的搜索空间，而是仅监测一部分搜索空间(也即第一搜索空间)，从而达到改变终端对下行控制信道的监测周期的目的。另外，由于第一搜索空间的监测周期大于等于调度时间间隔最小值，因此终端仅监测第一搜索空间，可以保证下行控制信道的监测时间能够与调度时间间隔最小值匹配。从而，终端在从一个搜索空间接收到下行控制信道之后，在调度时间间隔最小值对应的时长内，终端无需再次监测搜索空间，以使得终端可以关闭射频模块，以降低功耗。
实现方式三、网络设备在与调度时间间隔最小值对应的一组搜索空间中发送下行控制信道。可以理解的是，一组搜索空间包括一个或多个搜索空间。
需要说明的是，网络设备可以预先为终端配置了多组搜索空间，每一组搜索空间与一个调度时间间隔最小值对应。
可选的，对于一组搜索空间中的每一个搜索空间来说，搜索空间的监测周期可以等于对应的调度时间间隔最小值。
举例来说，网络设备为终端配置了三组搜索空间，第一组搜索空间对应的调度时间间隔最小值为3，第二组搜索空间对应的调度时间间隔最小值为4，第三组搜索空间对应的调度时间间隔最小值为5。在网络设备向终端指示调度时间间隔最小值为4的情况下，网络设备可以在第二组搜索空间中发送下行控制信道，不在第一组搜索空间和第三组搜索空间中发送下行控制信道。
可以理解的是，相比较于现有技术中网络设备可以在每一个配置给终端的搜索空间中发送下行控制信道，本申请实施例中，网络设备通过选择在一部分搜索空间(也即与调度时间间隔最小值对应的一组搜索空间)中发送下行控制信道，不在另一部搜索空间(也即不与调度时间间隔最小值对应的一组搜索空间)中发送下行控制信道，从而使得终端可以不用监测全部的搜索空间，而是仅监测一部分搜索空间(也即与调度时间间隔最小值对应的一组搜索空间)，从而达到改变终端对下行控制信道的监测周期的目的。另外，由于第一搜索空间的监测周期大于等于调度时间间隔最小值，因此终端仅监测第一搜索空间，可以保证下行控制信道的监测时间能够与调度时间间隔最小值匹配。从而，终端在从一个搜索空间接收到下行控制信道之后，在调度时间间隔最小值对应的时长内，终端无需再次监测搜索空间，以使得终端可以关闭射频模块，以降低功耗。
以上实现方式一至实现方式三仅是下行控制信道的监测周期的调整方式的示例，本申请实施例不限于此。
在本申请实施例中，对于下行控制信道的监测周期的调整方式，终端与网络设备所采用的实现方式是相同的，以保证终端能够正常接收到下行控制信道。需要说明的是，下行控制信道的监测周期的调整方式具体采用哪一种实现方式，是由标准定义的，或者终端与网络设备之间协商确定的。
需要说明的是，终端调整下行控制信道的监测周期，相应的，网络设备也需要调整下行控制信道的监测周期，从而网络设备与终端在下行控制信道的监测周期上才能够匹配，进而终端才能正常接收到下行控制信道。若终端由于未接收到第二指示信息而未调整下行控制信道的监测周期，但是网络设备已调整下行控制信道的监测周期，则终端与网络设备在下行控制信道的监测周期上不能匹配，导致终端不能正常接收到下行控制信道，影响了网络侧和终端之间的正常通信。因此，调度时间间隔最小值有必要进行限定，以减少终端未接收到第二指示信息所带来的不利影响。
可选的，调度时间间隔最小值的取值集合包括多个数值，所述多个数值是不相同的。并且，对于所述多个数值中的任意两个数值，所述两个数值中的一个数值是另一个数值的整数倍。例如，调度时间间隔最小值的取值集合可以为{0,2,4,8}。
这样一来，即使终端由于未接收到第二指示信息而不能够根据最新的调度时间间隔最小值，调整下行控制信道的监测周期，终端对应的下行控制信道的监测周期和网络设备对应的下行控制信道的监测周期也是整数倍的关系。从而，终端监测下行控制信道的时机和网络设备发送下行控制信道的时机不会完全错开，终端还可以接收到一部分下行控制信道。
基于图6所示的技术方案，通信装置根据调度时间间隔最小值，来调整下行控制信道的监测周期。这样一来，下行控制信道的监测周期可以与调度时间间隔最小值匹 配，以避免终端进行不必要的监测操作，从而避免终端进行频繁的“睡眠/唤醒”切换，达到降低终端功耗的目的。若下行控制信道的监测周期随着调度时间间隔最小值的变化而调整，则当调度时间间隔最小值较大时，下行控制信道的监测周期也较大。针对一些应用场景或者终端的业务类型，较大的下行控制信道的监测周期会减少数据调度机会，使得数据得不到及时调度，导致数据的传输时延增加。结合图8(a)和图8(b)进行举例说明。假设未调整前的下行控制信道的监测周期为2，网络设备所指示的调度时间间隔最小值为3。如图8(a)所示，在下行控制信道的监测周期不根据调度时间间隔最小值来调整的情况下，下行控制信道的监测周期依然为2。若终端的数据平均2个时隙到达一次，则网络设备可以及时调度终端接收数据，以使得数据的传输时延保持在稳定状态(也即数据的传输时延保持2个时隙)。如图8(b)所示，在下行控制信道的监测周期根据调度时间间隔最小值来调整的情况下，下行控制信道的监测周期从2调整为3。若终端的数据平均2个时隙到达一次，则由于下行控制信道的监测周期较大，因此网络设备不能及时调度终端接收数据，导致积累的待发数据越来越多，增加了数据的传输时延。参见图8(b)，时隙#1达到的数据需要在时隙#4上才能传输给终端，时隙#3到达的数据需要在时隙#7上才能传输给终端。可见，数据的传输时延逐渐增大。
当下行控制信道的监测周期不随着调度时间间隔最小值改变时，不能达到有效降低终端功耗的目的。但是，当下行控制信道的监测周期一直随着调度时间间隔最小值改变时，可能会导致数据的传输时延增大。因此，如何兼顾数据传输时延以及终端功耗，是一个亟待解决的技术问题。
为了解决上述技术问题，本申请实施例提供一种监测周期的调整方法，其技术原理在于：网络设备根据实际情况(例如终端的业务类型、应用场景)，向终端发送第一指示信息，以指示终端是否调整下行控制信道的监测周期，从而实现兼顾数据传输时延和终端功耗的目的。
如图9所示，为本申请实施例提供的一种监测周期的调整方法，该方法包括以下步骤：
S201、网络设备向终端发送第一指示信息，以使得终端接收来自网络设备的第一指示信息。
其中，所述第一指示信息用于指示终端在调度时间间隔最小值发生变化时是否调整下行控制信道的监测周期。
也就是说，第一指示信息可以用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期。或者，第一指示信息可以用于指示终端在调度时间间隔最小值发生变化时不需要调整下行控制信道的监测周期。
可选的，第一指示信息可以承载于RRC信令或者DCI中。第一指示信息可以为新增的信令。或者，第一指示信息可以复用现有的信令，以节省信令开销。
需要说明的是，第一指示信息可以采用各种实现方式，本申请实施例不限于此。
例如，若第一指示信息携带第一码点(code point)，则第一指示信息用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期。若第一指示信息携带第二码点，则第一指示信息用于指示终端在调度时间间隔最小值发生变化时 不需要调整下行控制信道的监测周期。
可以理解的是，第一码点不同于第二码点。第一码点和第二码点可以是标准中定义的，也可以是网络设备预先配置给终端的。
在第一指示信息复用现有的信令的情况下，第一码点和第二码点可以复用现有的信令中的码点。
例如，若第一指示信息包含第一预设字段，则第一指示信息用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期。若第一指示信息不包含第一预设字段，则第一指示信息用于指示终端在调度时间间隔最小值发生变化时不需要调整下行控制信道的监测周期。
在第一指示信息复用现有的信令的情况下，第一预设字段可以复用现有的信令中的字段。
在本申请实施例中，网络设备根据终端的业务类型、或者应用场景等因素，确定终端在调度时间间隔最小值发生变化时是否调整下行控制信道的监测周期。
例如，若当前的应用场景为低时延场景，例如车联网(vehicle to X，V2X)场景、uRLLC场景，则网络设备可以优先考虑数据传输时延，从而网络设备可以确定终端在调度时间间隔最小值发生变化时不调整下行控制信道的监测周期。
又例如，若当前的应用场景为低功耗场景，则网络设备可以优先考虑终端的功耗，从而网络设备可以确定终端在调度时间间隔最小值发生变化时不调整下行控制信道的监测周期。
又例如，在网络设备预测到终端的数据量较大的情况下，网络设备可以优先考虑数据传输时延，从而网络设备可以确定终端在调度时间间隔最小值发生变化时不调整下行控制信道的监测周期。
又例如，在网络设备预测到终端的数据量较小的情况下，网络设备可以优先考虑终端的功耗，从而网络设备可以确定终端在调度时间间隔最小值发生变化时不调整下行控制信道的监测周期。
S202、终端根据第一指示信息，确定是否调整下行控制信道的监测周期。
可以理解的是，若第一指示信息用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期，则终端确定需要调整下行控制信道的监测周期；若第一指示信息用于指示终端在调度时间间隔最小值发生变化时不需要调整下行控制信道的监测周期，则终端确定不需要调整下行控制信道的监测周期。
基于步骤S201-S202，网络设备可以根据终端的业务类型、或者应用场景等因素，确定终端在调度时间间隔最小值发生变化时是否需要调整下行控制信道的监测周期，从而网络设备向终端发送相应的第一指示信息，以使得下行控制信道的监测周期可以适用于终端的业务类型或者应用场景，从而达到兼顾数据传输时延和终端功耗的目的。
可选的，如图9所示，该监测周期的调整方法还可以包括以下步骤：
S203、网络设备向终端发送第二指示信息，以使得终端接收来自网络设备的第二指示信息。
其中，第二指示信息用于指示第一调度时间间隔最小值。可以理解的是，第一调度时间间隔最小值是调度时间间隔最小值的取值集合中的一个数值。
可选的，第二指示信息可以承载于DCI中。例如，第二指示信息可以承载于功耗节省信号中。
一种可能的设计中，第二指示信息和第一指示信息可以承载于不同的信令中。例如，第一指示信息承载于RRC信令中，第二指示信息承载于DCI中。
可以理解的是，若第二指示信息和第一指示信息承载于不同的信令中，则在每次调度时间间隔最小值改变时，网络设备无需向终端发送第一指示信息；相应的，终端可以根据之前网络设备所发送的第一指示信息，确定是否调整下行控制信道的监测周期。也即，网络设备可以在较长的时间内仅发送一条第一指示信息，以指示终端是否调整下行控制信道的监测周期。这样有利于节省信令开销。
另一种可能设计中，第二指示信息和第一指示信息可以承载于同一信令中。例如，第一指示信息和第二指示信息均承载于DCI中。示例性的，第一指示信息和第二指示信息可以承载于功耗节省信号中。
可以理解的是，第二指示信息和第一指示信息承载于同一信令中，从而网络设备在每次改变调度时间间隔最小值时，可以针对性地指示终端是否调整下行控制信道的监测周期，使得下行控制信道的监测周期可以更好地适应终端的业务类型。
在第二指示信息和第一指示信息承载于同一信令中时，第一指示信息和第二指示信息可以分别单独编码，也可以联合编码，本申请实施例不限于此。
示例性的，表5示出一种第一指示信息和第二指示信息进行联合编码的方案。

当然，第一指示信息和第二指示信息也可以采用其他联合编码的方案，本申请实施例不限于此。
在本申请实施例中，若第一指示信息用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期，则终端在接收到第二指示信息之后，终端可以执行下述步骤S204；在网络设备发送第二指示信息之前，或者在网络设备发送第二指示信息之后，网络设备可以执行下述步骤S205。
S204、终端根据第一调度时间间隔最小值，调整下行控制信道的监测周期。
S205、网络设备根据第一调度时间间隔最小值，调整下行控制信道的监测周期。
其中，步骤S204和步骤S205的实现方式可以参考步骤S102中的描述，在此不再赘述。
基于步骤S203-S205，终端通过调整下行控制信道的监测周期，以使得下行控制信道的监测周期可以匹配调度时间间隔最小值。这样一来，避免终端频繁的进行“睡眠/唤醒”的切换，有利于节省终端功耗。
如图10所示，为本申请实施例提供的一种监测周期的调整方法，该方法包括以 下步骤：
S301、网络设备向终端发送第三指示信息，以使得终端接收来自网络设备发送的第三指示信息。
其中，第三指示信息用于指示终端在调度时间间隔最小值发生变化时需要调整下行控制信道的监测周期。
可选的，第三指示信息承载于RRC信令中。
可以理解的是，若网络设备未向终端发送第三指示信息，或者说，终端未接收到第三指示信息，则说明终端在调度时间间隔最小值发生变化时不需要调整下行控制信道的监测周期。
S302、终端根据第三指示信息，确定需要调整下行控制信道的监测周期。
基于步骤S301-S302，网络设备可以根据终端的业务类型、或者应用场景等因素，确定终端在调度时间间隔最小值发生变化时是否需要调整下行控制信道的监测周期，从而网络设备向终端发送/不发送第三指示信息，以使得下行控制信道的监测周期可以适用于终端的业务类型或者应用场景，从而达到兼顾数据传输时延和终端功耗的目的。
可选的，如图10所示，该监测周期的调整方法还可以包括以下步骤：
S303、网络设备向终端发送第二指示信息，以使得终端接收来自网络设备的第二指示信息。
其中，第二指示信息用于指示第一调度时间间隔最小值。可以理解的是，第一调度时间间隔最小值是调度时间间隔最小值的取值集合中的一个数值。
可选的，第二指示信息可以承载于DCI中。例如，第二指示信息可以承载于功耗节省信号中。
可以理解的是，在网络设备向终端发送第三指示信息的前提下，终端在接收到第二指示信息之后，终端可以执行下述步骤S304；在网络设备发送第二指示信息之前，或者在网络设备发送第二指示信息之后，网络设备可以执行下述步骤S305。
S304、终端根据第一调度时间间隔最小值，调整下行控制信道的监测周期。
S305、网络设备根据第一调度时间间隔最小值，调整下行控制信道的监测周期。
其中，步骤S304和步骤S305的实现方式可以参考步骤S102中的描述，在此不再赘述。
基于图10所示的技术方案，网络设备通过发送第三指示信息和第二指示信息，以使得终端的下行控制信道的监测周期可以适用于终端的业务类型，从而达到兼顾数据传输时延和终端功耗的目的。
基于步骤S303-S305，终端通过调整下行控制信道的监测周期，以使得下行控制信道的监测周期可以匹配调度时间间隔最小值。这样一来，避免终端频繁的进行“睡眠/唤醒”的切换，有利于节省终端功耗。
如图11所示，为本申请实施例提供的一种能力上报方法，该方法包括以下步骤：
S401、网络设备向终端发送能力请求信息，以使得终端接收来自于网络设备的能力请求信息。
其中，能力请求信息用于请求终端上报能力指示信息。
例如，能力请求信息用于请求终端上报第一能力指示信息。进一步的，能力请求 信息还用于请求终端上报第二能力指示信息。
需要说明的是，步骤S401是可选的执行步骤。
S402、终端向网络设备发送第一能力指示信息，以使得网络设备接收来自于终端的第一能力指示信息。
其中，第一能力指示信息用于指示终端是否支持调度时间间隔最小值发生改变。也就是说，第一能力指示信息可以用于指示终端支持调度时间间隔最小值发生改变。或者，第一能力指示信息可以用于指示终端不支持调度时间间隔最小值发生改变。
在本申请实施例中，终端可以主动向网络设备发送第一能力指示信息；或者，终端在接收到网络设备发送的能力请求信息之后，终端再向网络设备发送第一能力指示信息。
可选的，第一能力指示信息承载于上行控制信息中。
可选的，第一能力指示信息可以复用现有的能力上报流程中的信令，以节省信令开销。
一种可能的设计中，第一能力指示信息可以以显式的方式指示终端是否支持调度时间间隔最小值发生改变。
例如，若第一能力指示信息携带第三码点，则第一能力指示信息用于指示终端支持调度时间间隔最小值发生改变。若第一能力指示信息携带第四码点，则第一能力指示信息用于指示终端不支持调度时间间隔最小值发生改变。可以理解的是，第五码点不同于第六码点。第五码点和第六码点可以是标准中定义的，也可以是网络设备预先配置给终端的。可以理解的是，第三码点不同于第四码点。第三码点和第四码点可以是标准中定义的，也可以是网络设备预先配置给终端的。
在第一能力指示信息复用现有的信令的情况下，第三码点和第四码点可以复用现有的信令中的码点。
又例如，若第一能力指示信息包含第二预设字段，则第一能力指示信息用于指示终端支持调度时间间隔最小值发生改变。若第一能力指示信息未包含第二预设字段，则第一能力指示信息用于指示终端不支持调度时间间隔最小值发生改变。
在第一能力指示信息复用现有的信令的情况下，第二预设字段可以复用现有的信令中的字段。
另一种可能的设计中，第一能力指示信息可以以隐式的方式指示终端是否支持调度时间间隔最小值发生改变。
例如，第一能力指示信息用于指示终端所支持的调度时间间隔最小值。例如，第一能力指示信息用于指示终端所支持的调度时间间隔最小值为{0,2,4,8}。又例如，第一能力指示信息用于指示终端所支持的调度时间间隔最小值为2。
在终端所支持的调度时间间隔最小值的数目大于1的情况下，则第一能力指示信息可以指示终端支持调度时间间隔最小值发生改变。在终端所支持的调度时间间隔最小值的数目为1的情况下，则第一能力指示信息可以指示终端不支持度时间间隔最小值发生改变。
可选的，如图11所示，该能力上报方法还可以包括步骤S403。
S403、终端向网络设备发送第二能力指示信息，以使得网络设备接收来自于终端 的第二能力指示信息。
其中，第二能力指示信息用于指示终端是否具有调整下行控制信道的监测周期的能力。也就是说，第二能力指示信息用于指示终端具有调整下行控制信道的监测周期的能力。或者，第二能力指示信息用于指示终端不具有调整下行控制信道的监测周期的能力。
在本申请实施例中，终端可以主动向网络设备发送第二能力指示信息；或者，终端在接收到网络设备发送的能力请求信息之后，终端再向网络设备发送第二能力指示信息。
可选的，第二能力指示信息可以承载于上行控制信息中。
可选的，第二能力指示信息可以复用现有的能力上报流程中的信令，以节省信令开销。
在本申请实施例中，第二能力指示信息和第一能力指示信息可以承载于同一信令中。或者，第二能力指示信息和第一能力指示信息可以承载于不同信令中。
可以理解的是，若第二能力指示信息和第一能力指示信息承载于同一信令中，则第一能力指示信息和第二能力指示信息可以分别独立编码；或者，第一能力指示信息和第二能力指示信息可以联合编码。
示例性的，表6示出一种第一能力指示信息和第二能力指示信息的联合编码方案。
表6
Figure PCTCN2020108018-appb-000006
需要说明的是，第二能力指示信息可以采用各种实现方式，本申请实施例不限于此。
例如，若第二能力指示信息携带第五码点，则第二能力指示信息用于指示终端具有调整下行控制信道的监测周期的能力。若第二能力指示信息携带第六码点，则第二能力指示信息用于指示终端不具有调整下行控制信道的监测周期的能力。
可以理解的是，第五码点不同于第六码点。第五码点和第六码点可以是标准中定义的，也可以是网络设备预先配置给终端的。
在第二能力指示信息复用现有的信令的情况下，第五码点和第六码点可以复用现有的信令中的码点。
又例如，若第二能力指示信息包含第三预设字段，则第二能力指示信息用于指示终端具有调整下行控制信道的监测周期的能力。若第二能力指示信息不包含第三预设字段，则第二能力指示信息用于指示终端不具有调整下行控制信道的监测周期的能力。
在第二能力指示信息复用现有的信令的情况下，第三预设字段可以复用现有的信令中的字段。
基于图11所示的技术方案，终端通过向网络设备发送能力指示信息(也即第一能 力指示信息，或者第一能指示信息和第二能力指示信息)，以使得网络设备获知终端的能力，以便于网络设备可以确定是否采用图9或图10所示的技术方案。
具体的，网络设备根据第一能力指示信息和第二能力指示信息，判断终端是否能够在所述调度时间间隔最小值发生变化时调整所述下行控制信道的监测周期。之后，网络设备根据判断结果，确定待发送的第一指示信息；或者，网络设备根据判断结果，确定是否发送第三指示信息。
可以理解的是，若第一能力指示信息用于指示终端不支持调度时间间隔最小值发生改变，和/或第二能力指示信息用于指示终端不具有调整下行控制信道的监测周期的能力，则网络设备的判断结果为：终端不能够在所述调度时间间隔最小值发生变化时调整所述下行控制信道的监测周期。从而，网络设备所发送的第一指示信息用于指示终端在调度时间间隔最小值发生变化时不调整下行控制信道的监测周期。或者，网络设备不发送第三指示信息。
可以理解的是，若第一能力指示信息用于指示终端支持调度时间间隔最小值发生改变，和/或第二能力指示信息用于指示终端具有调整下行控制信道的监测周期的能力，则网络设备的判断结果为终端能够在所述调度时间间隔最小值发生变化时调整所述下行控制信道的监测周期。从而，网络设备所发送的第一指示信息用于终端在调度时间间隔最小值发生变化时是否调整下行控制信道的监测周期。或者，网络设备可以发送/不发送第三指示信息。
