Description

通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在通信***中，终端设备需要监听物理下行控制信道(physical downlink control channel，PDCCH)，以确定网络设备是否有调度信息。网络设备可以向终端设备配置非连续接收(discontinuous reception，DRX)机制来降低终端设备的功耗。一个DRX周期至少包括一个DRX持续时间定时器(drx-on duration timer)的时间和可能的一段休眠(opportunity for drx)的时间。在DRX持续时间定时器未超时的时间段里，终端设备需要监听PDCCH，以获取调度信息。在休眠的时间段里，终端设备无需监听PDCCH，从而节省终端设备的功耗。
为了进一步降低终端设备的功耗，在一个DRX周期的DRX持续时间定时器所对应的时间段之前，网络设备可以向终端设备发送功耗节省信令，以指示终端设备在该DRX持续时间定时器所对应的时间段中，是否需要监听PDCCH：若是，则终端设备在该DRX持续时间定时器所对应的时间段监听PDCCH；若否，则终端设备在该DRX持续时间定时器所对应的时间段也保持休眠状态，以节省功耗。而在PDCCH传输功耗节省信令时，如何配置该PDCCH的搜索空间集和下行链路控制信息(downlink control information，DCI)的负载，尚未确定。
发明内容
本申请实施例提供一种通信方法及装置，能够成功配置PDCCH的搜索空间集和DCI的负载，节省信令开销。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种通信方法，该方法应用于网络设备或网络设备的芯片，该方法包括：网络设备向终端设备分别发送功耗节省信令的配置参数，之后，网络设备根据DCI的负载和/或搜索空间集，通过PDCCH向终端设备发送承载功耗节省信令的DCI。其中，功耗节省信令的配置参数包括下行链路控制信息DCI的负载和搜索空间集。DCI的负载用于指示DCI的比特数。DCI用于承载功耗节省信令，且通过物理下行控制信道PDCCH传输。搜索空间集用于确定PDCCH的监听时机。在向终端设备分别发送的配置参数中，至少一个终端设备的配置参数中有一个或多个搜索空间集和多个DCI的负载。

为了使得本申请实施例更加的清楚，首先对本申请实施例中涉及到的部分名词和处理过程作简单介绍。
带宽部分(bandwidth part，BWP)：指网络设备配置给终端设备在载波带宽内的部分频域资源。终端设备可以支持一个或多个载波，在一个载波上配置一个或多个BWP，即网络设备可以为终端设备在各个载波上分别配置一个或多个BWP，当配置多个BWP时，BWP之间可以重叠,也可以不重叠。在下行链路，终端设备可以配置一个或多个下行BWP，并且网络设备可以通过用户专用DCI切换激活的下行BWP。在激活的下行BWP之外，终端设备不会在非激活的下行BWP上接收物理下行共享信道(physical downlink shared channel，PDSCH)和物理下行控制信道(physical downlink control channel，PDCCH)。在上行链路，终端设备也可以配置一个或多个上行BWP，并且网络设备可以通过用户专用DCI切换激活的上行BWP。在激活的上行BWP之外，终端设备不会在非激活的上行BWP上发送物理上行共享信道(physical uplink shared channel，PUSCH)和物理上行控制信道(physical uplink control channel，PUCCH)。
搜索空间集(search space set)：用于确定终端设备监听PDCCH的监听时机，网络设备可以向终端设备配置物理下行控制信道(physical downlink control channel，PDCCH)的搜索空间集，终端设备按照配置的搜索空间集在各个监听时机上盲检测PDCCH。每个搜索空间集的配置可以包括如下信息：搜索空间集索引(用于区分不同的搜索空间集)、与该搜索空间集关联的控制资源集(control resource set，CORESET)索引、PDCCH监听周期和PDCCH监听周期内时隙偏移、时隙内PDCCH监听图样(pattern)(表示CORESET在一个时隙内起始符号)、搜索空间集的持续时间(表示该搜索空间集出现时连续的时隙个数)、PDCCH聚合等级(aggregation level，AL)、各聚合等级下的候选PDCCH(PDCCH candidates)个数、搜索空间集类型指示(如搜索空间集是公共搜索空间集(common search space set，CSS)，还是用户专用搜索空间集(user specific search space set，USS))、公共搜索空间集或者用户专用搜索空间集的下行链路控制信息(downlink control information，DCI)的格式(format)。终端设备根据上述搜索空间集中配置的PDCCH监听周期和PDCCH监听周期内时隙偏移、时隙内PDCCH监听图样，确定PDCCH监听时机(monitoring occasion)。网络设备可以向终端设备配置一个或者多个搜索空间集，用于监听PDCCH。对于一个服务小区的一个下行带宽部分(bandwidth part，BWP)，网络设备(如基站)通过无线资源控制(radio resource control，RRC)信令可以给终端设备配置最大10个搜索空间集。搜索空间集中PDCCH监听周期可以配置为1个时隙到2560个时隙中的某一个值。
公共搜索空间集和用户专用搜索空间集：公共搜索空间集主要用于广播公共信息或者发送组公共消息对应的控制信息，RRC信令中搜索空间集类型设置为“公共(common)”，即公共搜索空间集，公共搜索空间集的类型(type)可以包括多种，例如：Type 0 PDCCH公共搜索空间集、Type 0A PDCCH公共搜索空间集、Type 1 PDCCH公共搜索空间集、Type 2 PDCCH公共搜索空间集、Type 3 PDCCH公共搜索空间集。通常，公共搜索空间集会配置给小区内所有终端设备或一组终端设备；而用户专用搜索空间集主要用于发送该终端设备特有数据对应的控制信息，RRC信令中搜索空间集类型设置为“用户专用(ue-specific)”。公共搜索空间集和用户专用搜索空间集是可以有重叠的。
控制资源集：表示一个时频资源集合，用于承载PDCCH。终端设备在对应的控制资源集进行PDCCH的检测。在频域上，一个控制资源集由若干个资源块(resource block，RB)组成，频域大小和位置通过高层参数配置；在时域上，一个控制资源集的时域长度可以为1，2或3个时域符号，也是由高层参数配置。网络设备可以向终端设备配置一个或多个CORESET，终端设备在搜索空间集关联的CORESET上监听PDCCH。
网络设备通过无线资源控制(radio resource control，RRC)信令配置CORESET和搜索空间集，以使终端设备盲检测PDCCH。PDCCH的一种功能是承载数据的调度信息，终端设备需要根据CORESET和搜索空间集，确定PDCCH的监听时机，进而盲检测PDCCH，以获得调度信息。如果PDCCH有调度信息，那么终端设备根据调度信息通过PDSCH接收数据或者通过PUSCH发送数据。但是，在很多情况下，网络设备并不一定有调度信息要发送给终端设备，而终端设备需要周期性的盲检测PDCCH，浪费终端设备的功耗。
为了降低终端设备的功耗，网络设备可以向终端设备配置非连续接收(discontinuous reception，DRX)机制。DRX机制可以分为两种：空闲态(idle)的DRX和连接态的非连续接收(connected mode discontinuous reception，C-DRX)，这两种实现机制有所不同。其中，在空闲态的DRX下，终端设备主要监听网络设备的寻呼，终端设备在一个DRX周期(DRX cycle)监听一次寻呼时机(paging occasion)。
在连接态的非连续接收机制下，参见图1a，终端设备可以周期性的进入睡眠状态，不需要监听PDCCH。一个DRX周期至少包括一个DRX持续时间定时器(drx-on duration timer)的时间和可能的一段休眠(opportunity for drx)的时间。其中，一个DRX持续时间定时器的时间又称为“持续时间(on duration)”，一段休眠的时间又称为“休眠期”，是指DRX周期中的非激活时间(non-active time)。网络设备通过RRC信令向终端设备配置DRX参数，如DRX周期(DRX cycle)、DRX持续时间定时器(drx-on duration timer)、DRX非激活定时器(drx-inactivity timer)、DRX混合自动重传请求往返时间定时器(drx-hybrid auto repeat request round trip timer，drx-HARQ-RTT-Timer)、DRX重传定时器(drx-retransmission timer)等定时器参数。其中，终端设备在DRX持续时间定时器、DRX非激活定时器、下行链路(downlink，DL)的DRX重传定时器和上行链路(uplink，UL)的DRX重传定时器启动期间均需要监听PDCCH，这些时间也统称为激活时间(active time)。在非激活时间，终端设备可以进入睡眠状态，无需监听PDCCH，以节省功耗。
其中，DRX持续时间定时器：指示终端设备在DRX周期开始时连续监听PDCCH的时长。
DRX非激活定时器：当终端设备检测到PDCCH用于调度上行链路或下行链路初传数据时，启动(或重启)该定时器并保持持续监听PDCCH的时长。
DRX混合自动重传请求往返时间定时器：包括上行的drx-HARQ-RTT-Timer和下行的drx-HARQ-RTT-Timer，下行的drx-HARQ-RTT-Timer指示终端设备期望收到下行重传分配(assignment)之前的最小时长，上行的drx-HARQ-RTT-Timer指示终端设备期望收到上行重传授权之前的最小时长。
DRX重传定时器(drx-retransmission timer)：包括UL的DRX重传定时器和DL的DRX重传定时器，DL的DRX重传定时器用于规定终端设备期望获取下行重传的最大时长，UL的DRX重传定时器用于规定终端设备期望获取上行重传授权的最大时长。
以下行传输为例，DRX的大致过程：进入一个DRX周期后，在持续时间(on duration) 的时间段内，终端设备开始持续监听PDCCH：如果在持续时间的时间段内检测到PDCCH，且该PDCCH用于调度新传的数据(即PDCCH用于传输初传调度的调度信息)，那么，终端设备按照接收到的调度信息接收数据，并且启动DRX非激活定时器，每当终端设备检测到初传调度的调度信息，该DRX非激活定时器就被启动(或重启)一次，终端设备在DRX非激活定时器定时期间，持续监听PDCCH，直至DRX非激活定时器失效，终端设备进入休眠期，无需监听PDCCH；如果在持续时间的时间段内未检测到PDCCH，终端设备在持续时间的时间段结束后直接进入休眠期，如图1a所示。终端设备周期性的在各个持续时间的时间段内均需要检测PDCCH，图1a中以实线方格表示持续时间的时间段。
上述定时器参数的配置都是半静态的，也就是说，即使网络设备没有向终端设备发送调度信息，终端设备还是需要在持续时间的时间段打开接收机，来检测PDCCH。
为了进一步节省终端设备的功耗，在DRX机制的基础上引入功耗节省信令(power saving signal)，即在DRX的持续时间的时间段之前，网络设备向终端设备发送功耗节省信令，以指示终端设备是否在持续时间的时间段检测PDCCH，例如：若终端设备接收到功耗节省信令的唤醒(wake up)指示信息，则终端设备将启动DRX持续时间定时器，在该持续时间的时间段内需要监听PDCCH；若终端设备接收到功耗节省信令的休眠(go-to-sleep)指示信息，则终端设备将不启动DRX持续时间定时器，在该持续时间的时间段内无需监听PDCCH。或者，若终端设备检测到功耗节省信令，则终端设备启动DRX持续时间定时器，在该持续时间的时间段内需要监听PDCCH；若终端设备没有检测到功耗节省信令，则终端设备不启动DRX持续时间定时器，在该持续时间的时间段内无需监听PDCCH，如图1b所示。在图1b中，以实线所示出的持续时间的时间段，表示在该持续时间的时间段内，终端设备需要监听PDCCH，以虚线所示出的持续时间的时间段，表示在该持续时间的时间段内，终端设备无需监听PDCCH。另外，功耗节省信令还可以指示终端设备启动DRX持续时间定时器，但是在该持续时间的时间段内无需监听PDCCH，此时终端设备可以在持续时间的时间段内，发送或接收参考信号，以及基于参考信号进行测量。
其中，终端设备在持续时间的时间段之前监听功耗节省信令，功耗节省信令所在符号位置和持续时间的起始符号位置之间的偏移可以大于等于零。对于不同的终端设备而言，功耗节省信令所在符号位置和持续时间的起始符号位置之间的偏移可以相同，也可以不同。功耗节省信令所在符号位置和持续时间的起始符号位置之间的偏移的大小，可以通过搜索空间集中的配置信息确定，也可以通过直接配置PDCCH监听时机与持续时间的起始符号之间的偏移确定。或者，功耗节省信令所在时隙位置和持续时间的起始时隙位置之间的偏移可以大于等于零。对于不同的终端设备而言，功耗节省信令所在时隙位置和持续时间的起始时隙位置之间的偏移可以相同，也可以不同。功耗节省信令所在时隙位置和持续时间的时隙位置之间的偏移的大小，可以通过搜索空间集中的配置信息确定，也可以通过直接配置PDCCH监听时机与持续时间的时隙位置之间的偏移确定。
其中，功耗节省信令除了包括唤醒指示信息或休眠指示信息之外，还可以至少包括以下信息中的一种或多种信息：
最小时间单元偏移值：包括PDSCH的最小时间单元偏移值和/或PUSCH的最小时间单元偏移值。其中，PDSCH的最小时间单元偏移值用于指示PDCCH与PDCCH所调度的PDSCH之间在时间单元上的最小偏移量，在实际调度中，PDCCH与被调度的PDSCH之间的时间单 元偏移值大于或等于该最小时间单元偏移值；PUSCH的最小时间单元偏移值用于指示PDCCH与PDCCH所调度的PUSCH之间在时间单元上的最小偏移量，在实际调度中，PDCCH与被调度的PUSCH之间的时间单元偏移值大于或等于该最小时间单元偏移值。其中，时间单元的单位可以是以下单位中的任一个单位：无线帧、子帧、时隙、迷你时隙、正交频分复用(orthogonal frequency division multiplexing，OFDM)符号、微秒和毫秒。
示例性的，以时隙作为时间单元的单位，记PDSCH的最小时间单元偏移值为minimum K0，minimum K0指PDCCH与PDCCH所调度的PDSCH之间的最小时隙偏移值。在实际调度中，记PDSCH的时间单元偏移值为K0，若K0＝0，则表示PDCCH与PDCCH所调度的PDSCH可以在同一个时隙。若K0＞0，则表示PDCCH与PDCCH所调度的PDSCH不在同一个时隙。
记PUSCH的最小时间单元偏移值为minimum K2，minimum K2指PDCCH与PDCCH所调度的PUSCH之间的最小时隙偏移值。在实际调度中，记PUSCH的时间单元偏移值为K2，若K2＝0，则表示PDCCH与PDCCH所调度的PUSCH可以在同一个时隙。若K2＞0，则表示PDCCH与PDCCH所调度的PUSCH不在同一个时隙。其中，minimum K0大于0或minimum K2大于0，可以节省终端设备的功耗。
带宽部分(bandwidth part，BWP)标识：用于指示在DRX周期的持续时间的时间段内，处于激活状态的带宽部分。激活的BWP带宽越小，越能够节省终端设备的功耗。
多输入多输出(multiple input multiple output，MIMO)的最大层数：用于指示在DRX周期的持续时间的时间段内，PDCCH能够调度PDSCH或PUSCH的最大层数。终端设备可以基于最大层数，来开启或关闭一定数量的天线，从而节省终端设备的功耗。终端设备打开的天线越多，则终端设备功耗越大。
参考信号的指示信息：用于触发终端设备接收信道状态指示参考信号(channel state indicator reference signal，CSI-RS)或发送探测参考信号(sounding reference signal，SRS)。
PDCCH可以传输用户专用下行链路控制信息(downlink control information，DCI)或者组公共(group common)DCI。在本申请实施例中，当PDCCH通过组公共DCI传输功耗节省信令时，在公共搜索空间集上，网络设备通过PDCCH向一组终端设备传输组公共DCI。相应的，该组的各个终端设备接收来自网络设备的组公共DCI，根据组公共DCI中的公共搜索空间集，确定PDCCH的监听时机，在PDCCH的监听时机上，监听承载功耗节省信令的PDCCH。网络设备还需要向终端设备配置该组公共DCI的负载(payload size)。因此，在PDCCH传输功耗节省信令时，如何配置该PDCCH的搜索空间集和DCI的负载，是亟待解决的问题。

下面对本申请实施例提供的通信方法进行具体阐述。
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，在此统一说明，以下不再赘述。
本申请实施例提供一种通信方法，该通信方法应用在搜索空间集的配置的过程中。参见图3，该通信方法包括如下步骤：
S300、网络设备向终端设备分别发送DRX的配置信息。相应的，终端设备分别接收来自网络设备的DRX的配置信息。
其中，DRX的配置信息承载于RRC信令。DRX的配置信息可以包括DRX周期、DRX的持续时间等参数。各个终端设备的DRX的配置信息是相互独立的，各个终端设备的DRX周期、DRX的持续时间等参数可以相同，也可以不同。
持续时间DRX周期的周期类型可以有两种，即长DRX周期(long DRX cycle，LDC)和短DRX周期(short DRX cycle，SDC)。网络设备为终端设备配置DRX参数时，需要配置长DRX周期的参数，可选的，还可以配置短DRX周期的参数。
在DRX机制中，终端设备均需要配置长DRX周期的参数，不同终端设备的长DRX周期的周期长度可以相同，也可以不同。
在DRX机制中，短DRX周期是***可选的配置，即每个终端设备均配置长DRX周期之外，还可以配置短DRX周期。对于同一终端设备而言，长DRX周期的周期长度是短DRX周期的周期长度的整数倍，且长DRX周期的持续时间与短DRX周期的部分持续时间是重叠的。
需要说明的是，在本申请实施例中，长DRX周期描述为“第一周期类型的DRX周期”， 短DRX周期描述为“第二周期类型的DRX周期”。
示例性的，参见图4，图4示出的一种DRX配置状态，对于四个终端设备(终端设备1、终端设备2、终端设备3和终端设备4)而言，四个终端设备所配置DRX周期的周期类型相同，即均配置了第一周期类型的DRX周期(即长DRX周期)。各个终端设备的DRX周期的周期长度不同，且各个终端设备的持续时间的起始时刻和持续时间的时间长度也均存在差异。
示例性的，参见图5，图5示出的又一种DRX配置状态，两个终端设备分别记为第一终端设备和第二终端设备。第一终端设备配置第一周期类型的DRX周期(即长DRX周期)。第二终端设备配置第一周期类型的DRX周期(即长DRX周期)和第二周期类型的DRX周期(即短DRX周期)。对于第二终端设备而言，第一周期类型的DRX周期的周期长度是第二周期类型的DRX周期的周期长度的两倍。第一周期类型的DRX周期的持续时间的时间长度与第二周期类型的DRX周期的持续时间的时间长度相同。对于第一终端设备和第二终端设备而言，第一终端设备和第二终端设备的第一周期类型的DRX周期(即长DRX周期)的周期长度相同。第一终端设备和第二终端设备的持续时间的时间长度相同。
示例性的，参见图6，图6示出的再一种DRX配置状态，两个终端设备分别记为第一终端设备和第二终端设备。第一终端设备和第二终端设备均配置第一周期类型的DRX周期(即长DRX周期)。第一终端设备的DRX周期的周期长度是第二终端设备的DRX周期的周期长度的两倍。第一终端设备的DRX周期的持续时间的时间长度与第二终端设备的DRX周期的持续时间的时间长度相同。
需要说明的是，对于配置了两种周期类型的DRX周期(即第一周期类型的DRX周期和第二周期类型的DRX周期)的终端设备而言，终端设备可以在两种周期类型的DRX周期之间转换，即当终端设备处于第一周期类型的DRX周期(即长DRX周期)时，若终端设备在长DRX周期的持续时间的时间段内没有接收到调度信息，则终端设备继续处于长DRX周期。若终端设备在长DRX周期的持续时间的时间段内接收到调度信息，则终端设备将启动DRX非激活定时器(drx-inactivity timer)，DRX非激活定时器定时超时之后，终端设备将切换至短DRX周期。或者，网络设备向终端设备发送切换指令，以指示终端设备采用短DRX周期。当终端设备处于第二周期类型的DRX周期(即短DRX周期)时，若终端设备在若干个短DRX周期之内没有接收到调度信息，则终端设备切换至长DRX周期。
S301、网络设备向终端设备分别发送功耗节省信令的配置参数。相应的，终端设备分别接收来自网络设备的功耗节省信令的配置参数。
其中，配置参数通过RRC信令传输。配置参数包括DCI的负载和搜索空间集。
搜索空间集用于确定PDCCH的监听时机。一个搜索空间集用于确定终端设备监听PDCCH的一个或多个监听时机。在DRX的持续时间的时间段之前，终端设备可以在一个时隙内有一个或多个PDCCH的监听时机，也可以在多个时隙内有多个PDCCH的监听时机。示例性的，参见图7，图7示出了在一个搜索空间集中PDCCH的监听时机。在图7所示出的搜索空间集中，PDCCH的监听周期为四个时隙，PDCCH监听周期内时隙偏移为1，搜索空间集的持续时间为2个时隙，CORESET的时间长度为3个符号，则在时隙0、时隙1、时隙2和时隙3中，时隙1和时隙2中分别存在一个PDCCH的监听时机，且每个监听时机上PDCCH占用一个时隙中的三个符号，如图7中斜线填充的方格。如此，终端设备根据上述搜索空间集中 配置的PDCCH监听周期和PDCCH监听周期内时隙偏移、时隙内PDCCH监听图样，确定PDCCH监听时机(monitoring occasion)，来监听PDCCH。
DCI的负载用于指示DCI的比特数。承载功耗节省信令的DCI为组公共DCI，一个组中的不同终端设备的功耗节省信令在组公共DCI中的比特位置可以不同。参见图8，图8示出了一种组公共DCI的格式。一个组公共DCI可以包括N个域和循环冗余校验(cyclic redundancy check，CRC)。其中，每一块域用于承载一个终端设备的功耗节省信令。在图8中，示出了N个域，即从域1、域2、域3、〃〃〃、域N。其中，域1、域2、域3和域N分别对应图8中的一个实线方格，虚线方格表示从域4到域N-1之间的域。CRC用于差错控制，CRC对应图8中的一个实线方格。DCI的负载用于指示如图8中域1到域N的总比特数。组公共DCI通过PDCCH传输。
在本申请实施例中，承载功耗节省信令的DCI为组公共DCI，功耗节省信令的配置参数还可以包括位置指示信息，位置指示信息用于指示终端设备的功耗节省信令在组公共DCI中的比特位置，即该终端设备的功耗节省指令在组公共DCI中的域位置。示例性的，一个组包括两个终端设备，分别记为第一终端设备和第二终端设备，网络设备可以向两个终端设备分别发送功耗节省信令的配置参数。向第一终端设备发送的配置参数中的位置指示信息，用于为第一终端设备指示功耗节省信令在组公共DCI中的比特位置。向第二终端设备发送的配置参数中的位置指示信息，用于为第二终端设备指示功耗节省信令在组公共DCI中的比特位置。当终端设备有多个DCI的负载，该终端设备的功耗节省信令的配置参数中还可以包括多个位置指示信息。这是由于DCI的负载不同，若不同组公共DCI采用不同的DCI的负载，该终端设备在不同的组公共DCI中的比特位置也会不一样。位置指示信息与DCI的负载之间存在对应关系，不同的位置指示信息分别用于为该终端设备指示功耗节省信令在不同的DCI的负载的组公共DCI中的比特位置。或者，作为另一种可能的实现方式，网络设备和终端设备根据预定义的规则，确定各个终端设备的功耗节省信令在组公共DCI中的比特位置。
可选的，由于承载功耗节省信令的DCI为组公共DCI，且通过PDCCH传输。功耗节省信令的配置参数还可以包括无线网络临时标识(radio network temporary identity，RNTI)，该RNTI用于加扰承载功耗节省信令的DCI。网络设备向一个或多个终端设备发送的RNTI均相同，以使上述一个或多个终端设备采用相同的RNTI解扰承载功耗节省信令的DCI。因此，分配相同RNTI的一个或多个终端设备可以认为是同一组的终端设备。
可选的，功耗节省信令的配置参数中还可以包括：DCI承载的功耗节省信令的内容(也称为DCI承载的功耗节省信令的类型)，内容(或类型)包括：唤醒/休眠指示信息，最小时间单元偏移值，带宽部分标识，多输入多输出的最大层数，参考信号的指示信息中的一项或多项。上述配置参数中功耗节省信令的内容或类型适用于不同搜索空间集(如第一搜索空间集或第二搜索空间集)。例如，不同的搜索空间集配置相同的功耗节省信令的内容，即在不同搜索空间集上PDCCH承载的功耗节省信令的内容(或类型)可以相同。又例如，不同的搜索空间集分别配置相应的功耗节省信令的内容，即在不同搜索空间集上PDCCH承载的功耗节省信令的内容可以不同。再例如，不同的监听时机可以分别配置相应的功耗节省信令的内容，即在不同监听时机(如在长DRX周期的持续时间之前的监听时机、非长DRX周期的持续时间之前的监听时机)上，PDCCH承载的功耗节省信令的内容可以不同。
如此，终端设备在监听PDCCH时，即可根据网络设备配置的功耗节省信令的内容，来监听PDCCH。
在功耗节省信令的配置参数中，DCI的负载和搜索空间集的配置状况可以有如下两种方式：
方式一、DCI的负载与搜索空间集对应。在网络设备向终端设备分别发送的配置参数中，一个或一个以上的终端设备的配置参数中有多个搜索空间集和多个DCI的负载。在上述多个搜索空间集中，至少两个搜索空间集对应不同的DCI的负载。搜索空间集的数量和DCI的负载的数量可以相同，也可以不同。
示例性的，网络设备分别向两个终端设备(分别记为第一终端设备和第二终端设备)发送功耗节省信令的配置参数，向两个终端设备中的某一个终端设备(如第一终端设备)发送的功耗节省信令的配置参数中，可以包括一个DCI的负载和一个搜索空间集。向另一个终端设备(如第二终端设备)发送的配置参数功耗节省信令的配置参数中，可以包括两个DCI的负载和两个搜索空间集，这两个DCI的负载分别用于指示在这两个搜索空间集上传输PDCCH时所采用的负载。或者，向另一个终端设备(如第二终端设备)发送的功耗节省信令的配置参数中，可以包括两个DCI的负载和三个搜索空间集。在这三个搜索空间集中，有两个搜索空间集对应上述两个DCI的负载中的一个DCI的负载，而第三个搜索空间集对应上述两个DCI的负载中的另一个DCI的负载，即在其中两个搜索空间集上传输PDCCH时采用上述两个DCI的负载中的一个DCI的负载，在第三个搜索空间集上传输PDCCH时采用另一个DCI的负载。
在方式一的情况下，在不同搜索空间集上，需要监听PDCCH的终端设备的数量存在差异，所以不同搜索空间集对应的DCI的负载可以不一样。
示例性的，以功耗节省信令仅传输唤醒指示信息或休眠指示信息为例，在某一搜索空间集的监听时机上，需要监听PDCCH的终端设备的数量较少，则采用较小的DCI的负载即可传输功耗节省信令，而在另一搜索空间集的监听时机上，需要监听PDCCH的终端设备的数量较多，则采用较大的DCI的负载传输功耗节省信令。相对于现有技术中，在PDCCH向一组终端设备传输功耗节省信令时，不同搜索空间集上PDCCH均采用相同的DCI的负载传输功耗节省信令。而本申请实施例中，两个或多个搜索空间集能够对应不同的DCI的负载，以节省信令开销。
需要说明的是，在功耗节省信令的配置参数中，位置指示信息和DCI的负载有关。对于某一个终端设备(如第二终端设备)而言，若功耗节省信令的配置参数中包括两个DCI的负载(即第一DCI负载和第二DCI负载)和两个搜索空间集，则该功耗节省信令的配置参数也包括两个位置指示信息(即第一位置指示信息和第二位置指示信息)，两个位置指示信息分别与两个DCI的负载一一对应，即第一位置指示信息与第一DCI负载对应，为该终端设备指示功耗节省信令在第一DCI负载的组公共DCI中的比特位置。第二位置指示信息与第二DCI负载对应，为该终端设备指示功耗节省信令在第二DCI负载的组公共DCI中的比特位置。
对于同一组中的不同终端设备而言，搜索空间集的数量可以相同，也可以不同。导致搜索空间集的数量发生变化的情形有两种：
情形一、搜索空间集与DRX周期的周期类型有关。
其中，DRX周期和周期类型的表述可以参照S300中的相关描述，此处不再赘述。
同一组中的终端设备包括第一终端设备和第二终端设备。功耗节省信令的配置参数包括第一配置参数和第二配置参数；网络设备向第一终端设备发送第一配置参数，第一配置参数用于配置第一终端设备监听功耗节省信令所需的配置参数，网络设备向第二终端设备发送第二配置参数，第二配置参数用于配置第二终端设备监听功耗节省信令所需的配置参数。第一终端设备配置第一周期类型的DRX周期，第二终端设备配置第一周期类型的DRX周期和第二周期类型的DRX周期，第一配置参数中的搜索空间集的数量小于第二配置参数中的搜索空间集的数量。
示例性的，以图5所示出的DRX配置为例，第一终端设备配置第一周期类型的DRX周期(即长DRX周期)，第二终端设备配置第一周期类型的DRX周期(即长DRX周期)和第二周期类型的DRX周期(即短DRX周期)。第一终端设备和第二终端设备的第一周期类型的DRX周期(即长DRX周期)的周期长度相同，且第二终端设备的长DRX周期的周期长度是短DRX周期的周期长度的两倍。第一配置参数中包括一个搜索空间集，即第一配置参数包括第一搜索空间集，第一搜索空间集的PDCCH监听周期与第一周期类型的DRX周期(即长DRX周期)对应，如图5所示，依据第一搜索空间集可以确定PDCCH的监听时机为：监听时机1和监听时机3。第二配置参数中包括两个搜索空间集，即第二配置参数包括第一搜索空间集和第二搜索空间集。第一搜索空间集的PDCCH监听周期与第一周期类型的DRX周期(即长DRX周期)对应，如图5所示，依据第一搜索空间集可以确定PDCCH的监听时机为：监听时机1和监听时机3。第二搜索空间集的PDCCH监听周期与第二周期类型的DRX周期(即短DRX周期)对应，如图5所示，依据第二搜索空间集可以确定PDCCH的监听时机为：监听时机2。
情形二、搜索空间集与DRX周期的周期类型和周期长度有关。
其中，DRX周期和周期类型的描述可以参见S300的相关表述，此处不再赘述。
同一组中的终端设备可以分别记为第一终端设备和第二终端设备。功耗节省信令的配置参数包括第一配置参数和第二配置参数。网络设备向第一终端设备发送第一配置参数，第一配置参数用于配置第一终端设备监听功耗节省信令所需的配置参数，网络设备向第二终端设备发送第二配置参数，第二配置参数用于配置第二终端设备监听功耗节省信令所需的配置参数。第一终端设备和第二终端设备的DRX周期的周期类型相同，且第一终端设备的DRX周期的周期长度大于第二终端设备的DRX周期的周期长度，第一配置参数中的搜索空间集的数量小于第二配置参数中的搜索空间集的数量。
示例性的，以图6所示出的DRX配置为例，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)，第一终端设备的DRX周期的周期长度是第二终端设备的DRX周期的周期长度的两倍，第一配置参数中包括一个搜索空间集，即第一配置参数包括第一搜索空间集，第一搜索空间集的PDCCH监听周期与周期长度较长的DRX周期对应，可以确定PDCCH的监听时机为：监听时机1和监听时机3。第二配置参数中包括两个搜索空间集，即第二配置参数包括第一搜索空间集和第二搜索空间集。第一搜索空间集的PDCCH监听周期与周期长度较长的DRX周期对应，可以确定PDCCH的监听时机为：监听时机1和监听时机3。第二搜索空间集的PDCCH监听周期与周期长度较短的DRX周期对应，可以确定PDCCH的监听时机为：监听时机2。
在功耗节省信令的配置参数中，DCI的负载和搜索空间集的配置状况的另一种方式，即：
方式二、DCI的负载与监听时机对应。在网络设备向终端设备分别发送的功耗节省信令的配置参数中，一个或一个以上的终端设备的功耗节省信令的配置参数中有一个或多个搜索空间集和多个DCI的负载。该搜索空间集用于确定终端设备监听PDCCH的一个或多个监听时机。在一个或多个搜索空间集中，至少两个监听时机对应不同的DCI的负载，即在至少两个监听时机上通过PDCCH传输承载功耗节省信令的DCI时，该至少两个监听时机上的DCI采用的DCI的负载不同。具体地，可以分为两种场景：
场景一、在一个搜索空间集中的至少两个监听时机对应不同的DCI的负载。
示例性的，网络设备分别向两个终端设备(分别记为第一终端设备和第二终端设备)发送功耗节省信令的配置参数，向两个终端设备发送的功耗节省信令的配置参数中均包括一个搜索空间集。具体的，向两个终端设备中的某一个终端设备(如第一终端设备)发送的功耗节省信令的配置参数中，包括一个DCI的负载。网络设备向第一终端设备发送功耗节省信令时，一个搜索空间集的监听时机上PDCCH均采用一种DCI的负载。而向两个终端设备中的另一个终端设备(如第二终端设备)发送的功耗节省信令的配置参数中，包括两个DCI的负载，分别对应不同的监听时机。网络设备向第二终端设备发送功耗节省信令时，一个搜索空间集的三个监听时机中，通过其中两个监听时机上PDCCH可以对应一个DCI的负载，而另外一个监听时机上PDCCH对应另一个DCI的负载。
场景二、在多个搜索空间集中的至少两个监听时机对应不同的DCI的负载。具体的，不同的监听时机对应不同DCI的负载，这些监听时机可以对应同一个搜索空间集，也可以对应不同的搜索空间集。
示例性的，网络设备分别向两个终端设备(分别记为第一终端设备和第二终端设备)发送功耗节省信令的配置参数。具体的，向两个终端设备中的某一个终端设备(如第一终端设备)发送的功耗节省信令的配置参数中，包括一个搜索空间集和一个DCI的负载。在网络设备向第一终端设备发送功耗节省信令时，该搜索空间集的监听时机上PDCCH均采用相同的DCI的负载，即上述配置参数中的DCI的负载。向两个终端设备中的某一个终端设备(如第二终端设备)发送的功耗节省信令的配置参数中，包括两个搜索空间集和两个DCI的负载。在网络设备向第二终端设传输功耗节省信令时，两个搜索空间集的监听时机中，部分监听时机上PDCCH采用配置参数中的一个DCI的负载，这些监听时机可以是不同搜索空间集的，也可以是相同搜索空间集的。另外一部分的监听时机上PDCCH采用配置参数中的另一个DCI的负载，这些监听时机可以是不同搜索空间集的，也可以是相同搜索空间集的。
在方式二的情况下，针对不同监听时机上，需要监听PDCCH的终端设备的数量存在差异，所以不同监听时机上PDCCH的DCI的负载可以不一样。
示例性的，以功耗节省信令仅传输唤醒指示信息或休眠指示信息为例，在某一监听时机上，需要监听PDCCH的终端设备的数量较少，则采用较小的DCI的负载即可传输功耗节省信令，而在另一监听时机上，需要监听PDCCH的终端设备的数量较多，则采用较大的DCI的负载传输功耗节省信令。相对于现有技术中，在PDCCH向一组终端设备传输功耗节省信令时，不同监听时机上PDCCH均采用相同的DCI的负载传输功耗节省信令。而本申请实施 例中，两个或多个监听时机能够对应不同的DCI的负载，能够进一步地实现DCI的负载的灵活配置，以节省信令开销。
需要说明的是，在功耗节省信令的配置参数中，位置指示信息与DCI的负载有关。对于某一个终端设备(如第二终端设备)而言，若功耗节省信令的配置参数中包括两个DCI的负载(即第一DCI负载和第二DCI负载)和多个监听时机，则该功耗节省信令的配置参数也包括两个位置指示信息(即第一位置指示信息和第二位置指示信息)，两个位置指示信息分别与两个DCI的负载一一对应，第一位置指示信息与第一DCI负载对应，第一位置指示信息为第二终端设备指示功耗节省信令在第一DCI负载的组公共DCI中的比特位置。第二位置指示信息与第二DCI负载对应，第二位置指示信息为第二终端设备指示功耗节省信令在第二DCI负载的组公共DCI中的比特位置。
下面以“在一个搜索空间集中的至少两个监听时机对应不同的DCI的负载”为例，进行说明：
对于同一组中的不同终端设备而言，在一个搜索空间集中，至少两个监听时机所对应的DCI的负载不同。导致DCI的负载发生变化的监听时机有两种情形：
情形一、监听时机与DRX周期的周期类型有关。
同一组中的终端设备可以分别记为第一终端设备和第二终端设备。功耗节省信令的配置参数包括第一配置参数和第二配置参数。第一配置参数用于配置第一终端设备监听功耗节省信令所需的配置参数，第二配置参数用于配置第二终端设备监听功耗节省信令所需的配置参数。第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)。第二终端设备还配置了第二周期类型的DRX周期(即短DRX周期)。第一监听时机为第一周期类型的DRX周期的持续时间之前的监听时机，对应第一DCI负载。第二监听时机为非第一周期类型的DRX周期的持续时间之前的监听时机，对应第二DCI负载。第一DCI负载和第二DCI负载不同。
其中，非第一周期类型的DRX周期的持续时间可以是指：在第二周期类型的DRX周期的多个持续时间中，未与第一周期类型的DRX周期的持续时间重叠的持续时间。
示例性的，以图9为例，第一终端设备和第二终端设备均配置了长DRX周期，第一终端设备和第二终端设备的长DRX周期的周期长度相同。第二终端设备还配置了短DRX周期，且长DRX周期的周期长度是短DRX周期的周期长度的两倍。第一配置参数包括一个搜索空间集(记为第三搜索空间集)和一个DCI的负载，第三搜索空间集用于确定第一终端设备监听PDCCH的监听时机，记为第一监听时机。第二配置参数包括一个搜索空间集(记为第三搜索空间集)和两个DCI的负载，第三搜索空间集用于确定第二终端设备监听PDCCH的监听时机，分别记为第一监听时机和第二监听时机。其中，第一监听时机为第一周期类型的DRX周期的持续时间之前的监听时机，如图9中的监听时机1和监听时机3，对应第一DCI负载。第二监听时机为非第一周期类型的DRX周期的持续时间之前的监听时机，如图9中的监听时机2，对应第二DCI负载。其中，上述监听时机可以通过配置第三搜索空间集的PDCCH监听周期确定，第三搜索空间集的PDCCH监听周期与第一周期类型的DRX周期(即长DRX周期)和DRX周期长度有关。或者，上述监听时机也可以通过配置偏移值确定。其中，配置偏移值表示功耗节省信令的监听时机与DRX周期的持续时间的起始位置之间的时间偏移值。
在第一监听时机(如图9中的监听时机1和监听时机3)上，需要监听PDCCH的终端设备的数量为两个，即第一终端设备和第二终端设备，在第二监听时机(如图9中的监听时机2)上，需要监听PDCCH的终端设备的数量为1个，即第二终端设备。由于在第一监听时机(如图9中的监听时机1或监听时机3)上和第二监听时机(如图9中的监听时机2)上，需要监听PDCCH的终端设备的数量不同，所以，第一DCI负载与第二DCI负载可以不同。
情形二、监听时机与DRX周期的周期类型和周期长度有关。
同一组中的终端设备可以分别记为第一终端设备和第二终端设备。功耗节省信令的配置参数包括第一配置参数和第二配置参数。第一配置参数用于配置第一终端设备监听功耗节省信令所需的配置参数，第二配置参数用于配置第二终端设备监听功耗节省信令所需的配置参数。第一终端设备和第二终端设备的DRX周期的周期类型相同，第一终端设备的DRX周期的周期长度大于第二终端设备的DRX周期的周期长度。第一监听时机为周期长度较长的长DRX周期的持续时间之前的监听时机，对应第一DCI负载。第二监听时机为周期长度较短的长DRX周期的持续时间之前的监听时机，对应第二DCI负载。第一DCI负载和第二DCI负载不同。
需要说明的是，网络设备可以先执行S300，再执行S301，也可以先执行S301，再执行S300，还可以同时执行S300和S301，这里，对S300和S301的执行顺序不作限定。
S302、网络设备根据DCI的负载和/或搜索空间集，通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，终端设备根据DCI的负载和/或搜索空间集，通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。
其中，承载功耗节省信令的DCI为组公共DCI。网络设备是以组公共DCI的形式，向一组终端设备发送功耗节省信令。
一组的终端设备可以包括两个，即第一终端设备和第二终端设备。第一配置参数用于配置第一终端设备监听功耗节省信令所需的配置参数，第二配置参数用于配置第二终端设备监听功耗节省信令所需的配置参数。搜索空间集和DCI的负载的配置状况可以有两种方式(方式一和方式二)，在不同的方式下，对S302的具体实现过程进行说明：
方式一，至少一个终端设备的功耗节省参数中有多个搜索空间集和多个DCI的负载，其中至少两个搜索空间集对应不同的DCI的负载。对应不同的DCI的负载的搜索空间集分别记为第一搜索空间集和第二搜索空间集。
参见图10，S302可以具体实现为：
网络设备在第一搜索空间集上通过PDCCH向终端设备发送承载功耗节省信令的DCI，相应的，配置了第一搜索空间集的终端设备均在第一搜索空间集上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第一搜索空间集的终端设备无需在第一搜索空间集上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。这里，承载功耗节省信令的DCI的负载记为第一DCI负载。
网络设备在第二搜索空间集上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第二搜索空间集的终端设备在第二搜索空间集上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第二搜索空间集的终端设备无需在第二搜索空间集上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。这里，承载功耗节省信令 的DCI的负载记为第二DCI负载。第一DCI负载和第二DCI负载不同。
如此，在网络设备向终端设备分别发送的配置参数中，一个或一个以上的终端设备的配置参数中有多个搜索空间集和多个DCI的负载时，网络设备在多个搜索空间集上，通过PDCCH向终端设备发送承载功耗节省信令的DCI，多个搜索空间集中至少两个搜索空间集所对应的DCI的负载不同。相对于现有技术中，对于一种特定功能的组公共DCI，不同的搜索空间集均对应一个DCI的负载，导致信令开销大。而本申请实施例中，多个搜索空间集中至少两个搜索空间集所对应的DCI的负载不同，能够节省信令开销。
需要说明的是，在搜索空间集的监听时机上通过PDCCH传输功耗节省信令，监听时机位于DRX周期的持续时间之前，其中，持续时间是周期性出现的。下面以两种场景(场景一和场景二)为例进行说明：
场景一，一组终端设备中部分终端设备配置了两种周期类型的DRX周期，以图5为例，在图5所示出的DRX周期配置中，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)。第二终端设备还配置了第二周期类型的DRX周期(即短DRX周期)。此种场景下，S302可以具体实现为：
网络设备在第一周期类型的DRX周期对应的持续时间之前，在第一搜索空间集的监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第一搜索空间集的终端设备(第一终端设备和第二终端设备)在第一周期类型的DRX周期对应的持续时间之前，在第一搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。如图5所示，第一搜索空间集的监听时机可以是监听时机1或监听时机3。
网络设备在非第一周期类型的DRX周期对应的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第二搜索空间集的终端设备(第二终端设备)还需要在非第一周期类型的DRX周期对应的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第二搜索空间集的终端设备(第一终端设备)，无需在非第一周期类型的DRX周期对应的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。如图5所示，第二搜索空间集的监听时机可以是监听时机2。
其中，非第一周期类型的DRX周期对应的持续时间是指：在第二周期类型的DRX周期的多个持续时间中，未与第一周期类型的DRX周期的持续时间重叠的持续时间。
场景二，一组终端设备均配置了一种周期类型的DRX周期，但DRX周期的周期长度不同。以图6为例，在图6所示出的DRX周期配置中，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)。第一终端设备的长DRX周期的周期长度大于第二终端设备的长DRX周期的周期长度。网络设备对应不同DRX周期的周期长度的终端设备配置了不同数量的搜索空间集。不同搜索空间集的监听时机位于不同的持续时间之前。此种场景下，S302可以具体实现为：
网络设备在DRX周期的持续时间之前，在第一搜索空间集的监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第一搜索空间集的终端设备(第一终端设备和第二终端设备)均在DRX周期的持续时间之前，在第一搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。如图6所示，第一搜索空 间集的监听时机可以是监听时机1或监听时机3。
网络设备还需要在DRX周期的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH向该组的部分终端设备发送承载功耗节省信令的DCI。相应的，配置了第二搜索空间集的终端设备(第二终端设备)在DRX周期的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第二搜索空间集的终端设备(第一终端设备)，无需在DRX周期的持续时间之前，在第二搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。如图6所示，第二搜索空间集的监听时机可以是监听时机2。
方式二，一个或多个搜索空间集中，至少两个监听时机对应不同的DCI的负载。对应不同的DCI的负载的监听时机分别记为第一监听时机和第二监听时机。
参见图10，S302可以具体实现为：
网络设备在第一监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第一监听时机的终端设备均在第一监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第一监听时机的终端设备无需在第一监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。这里，承载功耗节省信令的DCI的负载记为第一DCI负载。
网络设备在第二监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第二监听时机的终端设备还在第二监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第二监听时机的终端设备无需在第二监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。这里，承载功耗节省信令的DCI的负载记为第二DCI负载。第一DCI负载和第二DCI负载不同。
如此，在网络设备向终端设备分别发送的配置参数中，至少一个终端设备的配置参数中有一个或多个搜索空间集和多个DCI的负载时，网络设备在多个监听时机上，通过PDCCH向终端设备发送承载功耗节省信令的DCI，而多个监听时机中至少两个监听时机所对应的DCI的负载不同，进一步实现了DCI的负载的灵活配置，以节省信令开销。
需要说明的是，在不同的监听时机上通过PDCCH传输功耗节省信令，监听时机位于DRX周期的持续时间之前，其中，持续时间是周期性出现的。下面以一种场景为例进行说明：
一组终端设备中部分终端设备配置了两种周期类型的DRX周期，以图9为例，在图9所示出的DRX周期配置中，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)。第二终端设备还配置了第二周期类型的DRX周期(即短DRX周期)。此种场景下，S302可以具体实现为：
网络设备在第一周期类型的DRX周期对应的持续时间之前，在第一监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第一监听时机的终端设备(第一终端设备和第二终端设备)在第一监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。其中，第一监听时机可以是图9中的监听时机1或监听时机3。
网络设备在非第一周期类型的DRX周期对应的持续时间之前，在第二监听时机上通过PDCCH向终端设备发送承载功耗节省信令的DCI。相应的，配置了第二监听时机的终端设备(第二终端设备)还需要在第二监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。未配置第二监听时机的终端设备(第一终端设备)无需在非第一周期类型 的DRX周期对应的持续时间之前，在第二监听时机上通过PDCCH接收来自网络设备的承载功耗节省信令的DCI。其中，“非第一周期类型的DRX周期对应的持续时间”可以参见方式一中的场景一的相关说明，此处不再赘述。
上述两种方式中，在不同搜索空间集或不同监听时机上，需要监听PDCCH的终端设备的数量不同，会导致DCI的负载发生变化。具体的：以方式一为例，在第一搜索空间集上，需要监听PDCCH的终端设备为两个，即第一终端设备和第二终端设备，如此，在第一搜索空间集上，承载功耗节省信令的组公共DCI中包括两个功耗节省信令，分别为指示第一终端设备是否监听PDCCH的信息和指示第二终端设备是否监听PDCCH的信息；在第二搜索空间集上，需要监听PDCCH的终端设备为一个，即第二终端设备，如此，在第二搜索空间集上，承载功耗节省信令的组公共DCI中包括一个功耗节省信令，指示第二终端设备是否监听PDCCH的信息。如此，第一DCI负载和第二DCI负载不同。
另外，在不同搜索空间集或不同监听时机上，传输的功耗节省信令的内容可以不同，也可以相同。
其中，功耗节省信令的内容不同，也可以描述为功耗节省信令的类型不同。示例性的，第一功耗节省信令的内容和第二功耗节省信令的内容不同，第一功耗节省信令的内容指示是否监听PDCCH的信息，如第一功耗节省信令包括唤醒指示信息，或休眠指示信息。第二功耗节省信令的内容除了指示是否监听PDCCH的信息之外，还可以至少包括如下信息的一种或多种信息：PDSCH的最小时间单元偏移值、PUSCH的最小时间单元偏移值、BWP标识、MIMO的最大层数、参考信号的指示信息。相比于第一功耗节省信令而言，由于第二功耗节省信令的内容除了指示是否监听PDCCH的信息之外，还可以至少包括其他的信息。如此，第二功耗节省信令的比特数增多，第一DCI负载和第二DCI负载不同。
功耗节省信令的内容相同，也可以描述为功耗节省信令的类型相同。功耗节省信令的内容相同可以是指：功耗节省信令包含相同的信息。例如，不同搜索空间集或者不同监听时机上功耗节省信令的内容均指示是否监听PDCCH的信息，或不同搜索空间集或者不同监听时机上功耗节省信令的内容均包括PDSCH的最小时间单元偏移值，或两个功耗节省信令的内容均包括BWP标识和MIMIO的最大层数。作为另一种导致DCI的负载发生变化的方式为：在多个搜索空间集中，至少在两个搜索空间集上传输的功耗节省信令的内容可以不同。在功耗节省信令的配置参数中，网络设备分别向终端设备配置在搜索空间集上监听功耗节省信令的内容。或者，在多个监听时机中，至少在两个监听时机上传输的功耗节省信令的内容可以不同。在功耗节省信令的配置参数中，网络设备向终端设备分别配置监听时机上监听功耗节省信令的内容。例如，在长DRX周期的持续时间之前的监听时机上监听功耗节省信令的内容、非长DRX周期的持续时间之前的监听时机上监听功耗节省信令的内容。
下面分两种情况对S302的具体实现过程进行说明：
情况一、在多个搜索空间集中，至少两个搜索空间集上传输的功耗节省信令的内容可以不同。两个终端设备均可以配置有两个搜索空间集，以传输不同内容的功耗节省信令，对应不同的DCI的负载。这两个搜索空间集为第一搜索空间集和第二搜索空间集。参见图11，S302可以具体实现为：
网络设备在第一搜索空间集的监听时机上通过PDCCH向终端设备发送承载第一功耗节省信令的DCI，相应的，配置了第一搜索空间集的终端设备，在第一搜索空间集的监听时 机上通过PDCCH接收来自网络设备的承载第一功耗节省信令的DCI。这里，承载第一功耗节省信令的DCI的负载记为第一DCI负载。
网络设备在第二搜索空间集的监听时机上通过PDCCH向终端设备发送承载第二功耗节省信令的DCI。相应的，配置了第二搜索空间集的终端设备，在第二搜索空间集的监听时机上通过PDCCH接收来自网络设备的承载第二功耗节省信令的DCI。这里，承载第二功耗节省信令的DCI的负载记为第二DCI负载。第一功耗节省信令和第二功耗节省信令不同。
以图12为例，在图12所示出的DRX周期配置中，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)，两个终端设备的长DRX周期的周期长度相同。两个终端设备的长DRX周期的持续时间的起始时刻和时间长度均相同。第一搜索空间集所确定的监听时机为：第一个持续时间和第三个持续时间之前的监听时机，如监听时机1和监听时机3。第二搜索空间集所确定的监听时机为：第二个持续时间之前的时机，如监听时机2。
如此，功耗节省信令的内容可以发生变化，在DCI的负载与搜索空间集对应时，两个或两个以上的搜索空间集可以有不同的DCI的负载，网络设备可以在不同的搜索空间集上指示的信息也不同，即在不同的搜索空间集上传输不同内容的功耗节省信令。相对于现有技术中，不同的搜索空间集上，网络设备向一组终端设备传输的功耗节省信令的DCI的负载均相同。而本申请实施例中，两个或两个以上的搜索空间集上，所传输的功耗节省信令的指示信息可以不同，可以采用不同的DCI的负载，有利于节省信令开销。
情况二、一个或多个搜索空间集中，至少在两个监听时机上传输的功耗节省信令的内容可以不同，对应不同的DCI的负载。两个终端设备均有多个监听时机，在不同的监听时机上可以传输不同内容的功耗节省信令。这两个监听时机为第一监听时机和第二监听时机。参见图11，S302可以具体实现为：
网络设备在第一监听时机上通过PDCCH向终端设备发送承载第一功耗节省信令的DCI。相应的，配置了第一监听时机的终端设备，在第一监听时机上通过PDCCH接收来自网络设备的承载第一功耗节省信令的DCI。这里，承载第一功耗节省信令的DCI的负载记为第一DCI负载。
网络设备在第二监听时机上通过PDCCH向终端设备发送承载第二功耗节省信令的DCI。相应的，配置了第二监听时机的终端设备，还在第二监听时机上通过PDCCH接收来自网络设备的承载第二功耗节省信令的DCI。未配置第二监听时机的终端设备，无需在第二监听时机上通过PDCCH接收来自网络设备的承载第二功耗节省信令的DCI。这里，承载第二功耗节省信令的DCI的负载记为第二DCI负载。第一功耗节省信令和第二功耗节省信令不同。
示例性的，以图9为例，在图9所示出的DRX周期配置中，第一终端设备和第二终端设备均配置了第一周期类型的DRX周期(即长DRX周期)。第二终端设备还配置了第二周期类型的DRX周期(即短DRX周期)。第一监听时机为：指第一周期类型的DRX周期的持续时间之前的监听时机，如监听时机1或监听时机3。第一终端设备和第二终端设备均在第一监听时机上通过PDCCH接收来自网络设备的承载第一功耗节省信令的DCI。第二监听时机为：指非第一周期类型的DRX周期的持续时间之前的监听时机，如监听时机2。第二终端设备在第二监听时机上通过PDCCH接收来自网络设备的承载第二功耗节省信令的DCI。第一终端设备无需在第二监听时机上通过PDCCH接收来自网络设备的承载第二功耗节省信 令的DCI。
如此，功耗节省信令的内容可以发生变化，至少两个监听时机可以有不同的DCI的负载，网络设备可以在不同的监听时机上传输不同内容的功耗节省信令。相对于现有技术中，不同的监听时机上，网络设备向一组终端设备传输的功耗节省信令的DCI的负载均相同。而本申请实施例中，至少监听时机上，所传输的功耗节省信令的指示信息可以不同，可以采用不同的DCI的负载，进一步节省了信令开销。
S303、终端设备根据功耗节省信令的信息，执行操作处理。
示例性的，终端设备根据接收到的功耗节省信令中的唤醒指示信息，在持续时间的时间段监听PDCCH，或者，根据接收到的功耗节省信令中的休眠指示信息，在持续时间的时间段仍保持休眠状态，或者，根据接收到的功耗节省信令中的参考信号的指示信息，来接收信道状态指示参考信号(channel state indicator reference signal，CSI-RS)或发送探测参考信号(sounding reference signal，SRS)，或基于CSI-RS进行测量。
本申请实施例提供的通信方法，网络设备向终端设备分别发送功耗节省信令的配置参数，之后，网络设备根据DCI的负载和/或搜索空间集，通过PDCCH向终端设备发送承载功耗节省信令的DCI。其中，功耗节省信令的配置参数包括DCI的负载和搜索空间集。DCI的负载用于指示DCI的比特数。DCI用于承载功耗节省信令，且通过PDCCH传输。搜索空间集用于确定PDCCH的监听时机。在向终端设备分别发送的配置参数中，至少一个终端设备的配置参数中有一个或多个搜索空间集和多个DCI的负载。相对于现有技术中，特定功能的组公共DCI仅有一个DCI的负载，信令开销大。而本申请实施例通信方法中，在网络设备向终端设备分别发送的配置参数中，至少一个终端设备的配置参数中有一个或多个搜索空间集和多个DCI的负载。如此，网络设备能够为至少一个终端设备配置不同数量的搜索空间集，并且，DCI的负载可以有多个，从而实现DCI的负载的灵活配置，网络设备在不同的搜索空间集或不同监听时机采用不同的DCI的负载，有利于节省信令开销。
