为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为了方便理解，以下对本发明实施例涉及的一些内容进行说明：
一、无线资源控制(Radio Resource Control，RRC)连接态非连续接收(Discontinuous Reception，DRX)。
一个基本的DRX周期(DRX cycle)如图1所示。如图1所示，一个DRX cycle可以由持续时间(On Duration)和DRX的机会(Opportunity for DRX)组成。其中，在On Duration的时间内，终端(也称为用户设备(User Equipment，UE))监听并接收PDCCH；在Opportunity for DRX时间内，UE不监听PDCCH，以节省功耗。
如果在On Duration内接收到了新传PDCCH，那么终端会启动或重启带宽部分(Bandwidth Part，BWP)非激活定时器(Inactivity Timer)来延长UE监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)的时长。
BWP Inactivity Timer由媒体接入控制(Medium Access Control，MAC)层管控，只有默认BWP(default BWP)才配有这个Timer。该定时器运行期间若有新传调度传输，则启动或重启动该定时器；定时器运行期间内若没有收到新传PDCCH，定时器到期后将当前激活BWP切换到default BWP，也就是说设 置当前激活BWP为default BWP。
需要说明的是，一个DRX cycle也可以由激活时间(Active Time)和非激活时间(Outside Active Time)组成。DRX周期的激活时间大于或等于DRX周期的持续时间。若某DRX周期终端启动或重启了Inactivity Timer，则该DRX周期的激活时间大于该DRX周期的持续时间，具体地，该周期的Active Time包括该DRX周期中的On Duration以及Inactivity Timer处于运行状态的时间。若某DRX周期终端未启动或重启Inactivity Timer，则该DRX周期的激活时间等于该DRX周期的持续时间。具体请参见图1。
二、DCP及非激活时间辅小区休眠指示(SCell Dormancy Indication)。
DCP全称为节能无线网络临时标识(Power Saving-Radio Network Temporary Identifier，PS-RNTI)加扰的DCI格式2-6(DCI format 2_6with CRC scrambled by PS-RNTI)。
为了在DRX配置下进一步节能，网络可以在配置了DRX机制下，给UE进一步配置DCP。
DCP中唤醒指示(Wake Up indication)用于指示UE是否开启下一个DRX周期持续时间定时器(onduration Timer)或DCP指示MAC层是否开启下一个DRX周期onduration Timer，启动timer意味着UE要在timer内监听PDCCH，反之不监听PDCCH。DCP只能配置在主小区(Primary cell，Pcell)上。DCI格式2-6存在于Outside Active Time也就是Active time之外。需要说明的是，只有在配了DRX时，才能配置DCP。
DCI format 2-6可以包括以下两个信息域：
唤醒指示(Wake-up indication)域，用于指示UE是否开启下一个DRX周期的ondurationtimer，大小为1比特(bit)；
Scell Dormancy Indication域，用于指示载波聚合(Carrier Aggregation，CA)下，UE的辅小区(Secondary Cell，SCell)是否进入休眠行为，大小可以是0、1、2、3、4或5bits。
此外，DCI格式2-6中SCell Dormancy Indication域可以以SCell组(group)为单位来指示SCell group是否切换到休眠BWP(dormant BWP)。该域中每个比特对应指示一个SCell group。
三、Active Time内的SCell Dormancy Indication。
方式一、通过DCI format 1-1，0-1来同时调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和SCell Dormancy Indication.
方式二、通过DCI format 1-1进行SCell Dormancy Indication且不调度PDSCH。
在方式二中，DCI format 1-1可以通过重用以下调度相关域来进行Dormancy Indication：调制编码方案(Modulation and Coding Scheme，MCS)、新数据指示(New Data Indication，NDI)、解调参考信号(Demodulation Reference Signal，DMRS)序列初始化(sequence initialization)、冗余版本(Redundant Version，RV)、混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程数(process number)、天线端口(Antenna port(s))。
其中，MCS的比特大小为5bits；NDI的比特大小为1bit；DMRS sequence initialization的比特大小为0或1bit；RV的比特大小为2bits；HARQ process number的比特大小为4bits；天线端口至少为4bits，如4至6bits。
四、BWP切换时延(BWP switch delay)T BWPswitchDelay。
表1：T BWPswitchDelay
Figure PCTCN2021087732-appb-000001
T BWPswitchDelay可以参见表1。如表1所示，T BWPswitchDelay与μ、新空口(New Radio，NR)时隙(Slot)长度(length)及BWP切换类型相关。其中，μ是调度DCI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的子载波间隔(SubCarrier Space，SCS)配置和携带有DCI检测的混合自动重传请求应答(Hybrid Automatic Repeat Request Acknowledgement，HARQ-ACK)信息的物理上行控制信道(Physical Uplink Control Channel，PUCCH)的SCS配置之间的最小SCS(μ is the smallest SCS configuration between the SCS  configuration of the PDCCH providing the DCI and the SCS configuration of a PUCCH with the HARQ-ACK information in response to the detection of the DCI)。
需要说明的是，对于表1中的BWP切换类型1，T BWPswitchDelay取决于终端能力(UE capability)(T BWPswitchDelay depends on UE capability)。对于表1中的BWP切换类型2，如果BWP切换涉及到SCS的变化，则BWP切换时延由切换前SCS与切换后SCS之间的较大时延决定(If the BWP switch involves changing of SCS,the BWP switch delay is determined by the larger one between the SCS before BWP switch and the SCS after BWP switch)。
以下对本发明实施例的节能模式指示方法进行说明。
参见图2，图2是本发明实施例提供的节能模式的指示方法的流程图之一。本发明实施例的节能模式的指示方法应用于终端。在实际应用中，终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
如图2所示，应用于终端的节能模式的指示方法可以包括以下步骤：
步骤201、接收第一下行控制信息DCI。
其中，所述第一DCI为不调度数据的DCI，所述第一DCI用于指示所述终端的第一小区切换到或激活目标节能模式。
具体实现时，第一DCI可以显式或隐式的指示终端的第一小区切换到或激活目标节能模式。
在本申请的一些实施例中，所述第一DCI为不调度数据的DCI，所述第一DCI包括节能模式指示域，也就是说，所述第一DCI可以通过节能模式指示域进行节能模式切换或激活的指示，但不限于此。
具体实现时，若终端当前存在激活的节能模式，则所述节能模式指示域可以指示所述第一小区切换到目标节能模式；若终端当前不存在激活的节能模式，则所述节能模式指示域可以指示所述第一小区激活目标节能模式。
为方便理解，示例说明如下：
假设目标节能模式为节能模式1。
若终端在接收到所述不调度数据的第一DCI之前存在激活的节能模式2， 则终端在接收到所述不调度数据的第一DCI后，可以根据节能模式指示将所述第一小区从节能模式2切换到或变更到节能模式1。
若终端在接收到所述不调度数据的第一DCI之前不存在激活的节能模式，则终端在接收到所述不调度数据的第一DCI后，可以在所述第一小区上激活节能模式1。
本实施例的节能模式的指示方法，通过不调度数据的第一DCI中的节能模式指示域指示所述终端的第一小区切换到或激活目标节能模式，可以提高终端切换或激活节能模式的效率，进而实现终端节能。
在图2对应的实施例中，可选的，所述接收第一DCI之后，所述方法还可以包括：
在目标时刻执行所述第一DCI所指示的行为，所述目标时刻为：
第i个时域资源的起始时刻，其中，所述终端在第i-1个时域资源内完成所述第一DCI的接收，i为正整数；或，
第一时刻，所述第一时刻与所述第i-1个时域资源的结束时刻间隔所述目标节能模式的生效时延，且所述第一时刻位于所述第i-1个时域资源之后。
在本可选实施方式中，所述在目标时刻执行所述第一DCI所指示的行为，指的是在目标时刻执行所述节能模式指示域所指示的所述终端的第一小区切换到或激活目标节能模式。
终端在接收到所述第一DCI之后，执行节能模式指示域的指示，将所述第一小区切换到目标节能模式，或，在所述第一小区激活目标节能模式。
但应理解的是，在某些实施方式中，终端在接收到所述第一DCI后，也可以不执行所述节能模式域所指示的行为。例如，终端未接收到所述第一DCI或错检了所述第一DCI时，可以不执行所述第一DCI所指示的行为。
以下对本可选实施方式中所述目标时刻进行说明：
场景一、所述目标时刻为第i个时域资源的起始时刻。
具体实现时，所述第i个时域资源的起始时刻可以理解为：接收第一DCI之后的第1个时域资源的起始时刻。
在场景一中，终端在第i-1个时域资源内完成所述第一DCI的接收之后，即可在第i个时域资源的起始时刻，执行所述第一DCI所指示的行为，从而可 以进一步提高节能模式切换或激活的效率，进而实现终端节能。
具体实现时，完成所述第一DCI的接收可以理解为：接收到所述第一DCI，但未完成对所述第一DCI的解码；或，接收到所述第一DCI且完成对所述第一DCI的解码。时域资源可以为正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号或时隙(Slot)，但不仅限于此。
如：假设终端在第3个时隙的第2个OFDM符号完成所述第一DCI的接收，可以包括如下实现方式：
第一种实现方式，终端可以在第3个时隙的第3个OFDM符号的开始时刻，执行所述第一DCI所指示的行为。
第二种实现方式，终端在第3个时隙的第2个OFDM符号完成所述第一DCI的接收，在第3个时隙的第3个OFDM符号内完成所述第一DCI的解码，终端可以在第3个时隙的第4个OFDM符号的开始时刻，执行所述第一DCI所指示的行为。
第三种实现方式，终端在第3个时隙的第2个OFDM符号完成所述第一DCI的接收，可以在第4个时隙的第1个OFDM符号的开始时刻，执行所述第一DCI所指示的行为。
第四种实现方式中，终端在第3个时隙的第2个OFDM符号完成所述第一DCI的接收，在第3个时隙的第3个OFDM符号内完成所述第一DCI的解码，终端可以在第4个时隙的第1个OFDM符号的开始时刻，执行所述第一DCI所指示的行为。
场景二、所述目标时刻为第一时刻，所述第一时刻与所述第i-1个时域资源的结束时刻间隔所述目标节能模式的生效时延，且所述第一时刻位于所述第i-1个时域资源之后。
具体实现时，所述第一时刻可以理解为：所述第一DCI所在时域资源之后的第一时刻，所述第一时刻与所述第一DCI所在时域资源的结束时刻间隔第一时长，所述第一时长为所述目标节能模式的生效时延。
在场景二中，终端在完成所述第一DCI的接收后，在所述目标节能模式的生效时延后，才执行所述第一DCI所指示的行为。这样，终端在所述目标节能模式的生效时延内还可以处理之前调度的数据的重传和/HARQ反馈，从而 可以提高数据传输的可靠性。
具体实现时，在所述目标节能模式的生效时延期间，终端可以保持在目标节能模式未生效前，也就是当前生效的节能模式上正常工作。
可选的，所述目标节能模式的生效时延可以包括或不包括所述第一DCI的解码时间。
可选的，所述目标节能模式的生效时延由网络侧设备配置或由协议约定。
进一步地，在所述目标节能模式的生效时延由网络侧设备配置的情况下，所述第一DCI还包括所述目标节能模式的生效时延指示。也就是说，可以通过所述第一DCI同时指示切换或激活目标节能模式以及目标节能模式的生效时延，从而可以节省信令开销。需要说明的是，所述目标节能模式的生效时延可以通过所述第一DCI的节能模式指示域指示，或，可以通过所述第一DCI中除所述节能模式指示域之外的其他指示域指示。
例如，通过所述第一DCI中的PDSCH-to-HARQ_feedback timing indicator指示域，来指示目标节能模式的生效时延的取值。所述目标节能模式的生效时延的取值可以与协议约定的PDSCH-to-HARQ_feedback timing indicator中所指示的K1的取值相同，或大于等于K1的值。需要说明的是，本发明对所述目标节能模式的生效时延的取值不作限制。
应理解的是，在其他实施方式中，在所述目标节能模式的生效时延由网络侧设备配置的情况下，网络侧设备可以通过除所述第一DCI之外的指示信息指示所述目标节能模式的生效时延，从而可以提高信息指示的灵活度。
可选的，所述目标节能模式的生效时延与以下任意一项相关：混合自动重传请求应答(Hybrid Automatic Repeat Request Acknowledgement，HARQ-ACK)反馈处理时延、HARQ-ACK反馈重传最大时延、最大重传次数与重传最大时延的乘积、带宽部分BWP的切换时延、所述终端的节能模式切换的能力、所述终端期望的节能模式生效时延。具体说明如下：
a)在所述目标节能模式的生效时延与HARQ-ACK反馈处理时延相关的情况下，可选的，所述目标节能模式的生效时延可以大于或等于HARQ-ACK反馈处理时延。这样，终端在所述目标节能模式的生效时延还可以进行HARQ-ACK反馈处理，从而可以提高数据传输的可靠性。
进一步地，所述HARQ-ACK反馈处理时延可以是第二DCI的HARQ-ACK反馈处理时延，所述第二DCI为不调度数据且包含辅小区休眠指示的DCI format 1_1，但不仅限于此。
b)在所述目标节能模式的生效时延与HARQ-ACK反馈重传最大时延相关的情况下，可选的，所述目标节能模式的生效时延可以大于或等于HARQ-ACK反馈重传最大时延。这样，终端在所述目标节能模式的生效时延内可以完成HARQ-ACK反馈重传，从而可以提高数据传输的可靠性。
c)在所述目标节能模式的生效时延与最大重传次数与重传最大时延的乘积相关的情况下，可选的，所述目标节能模式的生效时延可以大于或等于最大重传次数与重传最大时延的乘积。这样，可以保证终端在所述目标节能模式的生效时延内完成数据重传，从而可以提高数据传输的可靠性。
d)在所述目标节能模式的生效时延与BWP的切换时延相关的情况下，可选的，所述目标节能模式的生效时延可以大于或等于BWP的切换时延。
e)在所述目标节能模式的生效时延与所述终端的节能模式切换的能力相关的情况下，所述目标节能模式的生效时延可以由网络侧设备配置。具体实现时，一种实现方式中，终端可以向网络侧设备上报所述终端的节能模式切换的能力，以使网络侧设备根据终端上报的所述终端的节能模式切换的能力确定所述目标节能模式的生效时延，并将该目标节能模式的生效时延配置给终端。另一种实现方式中，终端可根据所述终端的节能模式切换的能力确定一个参考生效时延，并将参考生效时延上报给网络侧设备，以使网络侧设备根据参考生效时延确定所述目标节能模式的生效时延，并将该目标节能模式的生效时延配置给终端。所述由网络侧设备配置的目标节能模式的生效时延可以大于或等于参考目标节能模式的生效时延。
f)在所述目标节能模式的生效时延与所述终端期望的节能模式生效时延相关的情况下，所述目标节能模式的生效时延可以由网络侧设备配置。具体实现时，终端可以上报期望的目标节能模式生效时延，以使网络侧设备根据期望的目标节能模式生效时延确定所述目标节能模式的生效时延，并将所述目标节能模式的生效时延配置给终端。所述由网络侧设备配置的目标节能模式的生效时延可以大于或等于期望目标节能模式的生效时延。
需要说明的是，在终端上报所述终端的目标节能模式切换能力、参考目标节能模式生效时延或终端期望的目标节能模式生效时延的场景中，网络侧设备可以自主决策是否根据终端上报的内容确定所述目标节能模式的生效时延，也就是说，网络侧设备最终配置的所述目标节能模式的生效时延可以基于终端上报的内容确定，也可以不基于终端上报的内容确定。如：终端上报所述终端期望的目标节能模式生效时延，但网络侧设备最终配置的目标节能模式生效时延等于BWP的切换时延，而不等于所述终端期望的目标节能模式生效时延。
在图2对应的实施例中，所述第一DCI可以通过以下方式指示所述目标节能模式：
方式一、所述第一DCI可以直接指示所述目标节能模式。
在图2对应的实施例中，可选的，所述目标节能模式可以由以下至少一项参数来确定：
所述目标节能模式的标识或索引、目标BWP、所述目标节能模式的生效时延、发射天线或发射通道的数量、接收天线或接收通道的数量、最大下行多输入多输出MIMO层数、最大上行MIMO层数、激活时间相同的上行分量载波、激活时间相同的下行分量载波、物理下行控制信道PDCCH与其调度的物理下行共享信道PDSCH之间的时间间隔、所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔、PDCCH与其调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)之间的时间间隔、PDSCH处理时延、PUSCH准备时延、控制资源集(Control Resource Set，CORESET)、搜索空间组(Search Space Set Group)、搜索空间、PDCCH监听周期、PDCCH监听偏移量、PDCCH监听持续时间、BWP的带宽大小、最大上行传输速率、最大下行传输速率、非连续接收DRX周期、所述终端同时处理的信道状态信息(Channel State Information，CSI)报告的数量、所述终端同时处理的波束管理报告的数量、所述终端同时接收或处理的测量资源的数量、CSI报告相关的时延、波束管理报告相关的时延。
以下对上述各项参数进行说明：
可选的，所述目标BWP可以为以下任意一项：休眠BWP(dormant BWP)、默认BWP(default BWP)、第一激活BWP(first active BWP)、第一非休眠BWP (first non-dormant BWP)、所述终端所配置的BWP中的任一个BWP。
具体实现时，所述目标BWP可以通过标识或索引等方式指示，应理解的是，其他参数如：CORESET、Search Space Set Group、搜索空间等参数也可以通过类似的方式指示。
在实际应用中，first active BWP可以为RRC配置参数。第一非休眠BWP可为RRC配置参数，如first-non-dormant-BWP-ID-for-DCI-outside-active-time。
所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔指的是UE在接收完所述第一DCI所在的PDCCH后，并在所述时间间隔后的第一个时隙上发送所述第一DCI的HARQ-ACK反馈。具体可以为：所述第一DCI与其确认应答(Acknowledgement，ACK)之间的时间间隔，或，所述第一DCI的与其否定应答(Negative Acknowledgement，NACK)之间的时间间隔。
例如，所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔为4个时隙slots。终端在第3个时隙的第2个OFDM符号完成所述第一DCI的接收后，4个时隙后，在第8个时隙进行所述第一DCI的HARQ-ACK反馈。
在方式一中，所述第一DCI可以通过携带上述至少一项参数，来直接指示所述目标节能模式。
需要说明的是，在实际应用中，所述第一DCI可以仅通过所述节能模式指示域指示所述终端的第一小区切换到或激活目标节能模式的行为，但所述目标节能模式的确定参数可以不通过所述节能模式指示域指示，也就是说，所述目标节能模式的确定参数可以通过所述第一DCI中除所述节能模式指示域中之外的其他域指示。
例如，所述目标节能模式指的是目标BWP。网络配置所述第一DCI中包括目标BWP、所述目标BWP的生效时延以及所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔。UE通过接收所述第一DCI，根据所述目标BWP的生效时延，在生效时延之后的第一个时隙上将当前激活的BWP切换到所述目标BWP上。此外，根据所述目标BWP的生效时延以及所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔，在时间间隔之后的第一个时隙上反馈所述第一DCI的PDCCH的HARQ-ACK。
方式二、所述第一DCI可以动态指示网络侧设备配置的N个节能模式中 的一个节能模式作为目标节能模式。
在方式二中，可选的，所述接收第一DCI之前，所述方法还包括：
接收配置信息，所述配置信息用于配置N个节能模式，N为正整数；
其中，所述目标节能模式为所述N个节能模式中的一个节能模式。
具体实现时，网络侧设备在通过所述配置信息配置N个节能模式之后，可以包括以下实现方式：
第一实现方式、网络侧设备可以直接通过所述第一DCI动态指示所述N个节能模式中的一个节能模式为所述目标节能模式。
第二实现方式、进一步地，所述接收配置信息之后，所述接收第一下行控制信息DCI之前，所述方法还包括：
接收第一信息，所述第一信息用于激活所述N个节能模式中的K个节能模式，K为小于或等于N的正整数；
其中，所述目标节能模式为所述K个节能模式中的一个节能模式。
在第二实现方式中，网络侧设备在通过所述配置信息配置N个节能模式之后，还可以通过所述第一信息激活所述N个节能模式中的K个节能模式，最后通过所述第一DCI指示激活的所述K个节能模式中的一个节能模式为所述目标节能模式。
具体实现时，所述配置信息可以为RRC信令，所述第一信息可以为媒体接入控制(Medium Access Control，MAC)控制单元(Control Element，CE)，但不仅限于此。
可选的，所述节能模式由以下至少一项参数来确定：
所述节能模式的标识或索引、目标BWP、所述节能模式的生效时延、发射天线或发射通道的数量、接收天线或接收通道的数量、最大下行多输入多输出MIMO层数、最大上行MIMO层数、激活时间相同的上行分量载波、激活时间相同的下行分量载波、物理下行控制信道PDCCH与其调度的物理下行共享信道PDSCH之间的时间间隔、所述第一DCI的PDCCH与其HARQ-ACK之间的时间间隔、PDCCH与其调度的物理上行共享信道PUSCH之间的时间间隔、PDSCH处理时延、PUSCH准备时延、控制资源集CORESET、搜索空间组、搜索空间、PDCCH监听周期、PDCCH监听偏移量、PDCCH监听持续 时间、BWP的带宽大小、最大上行传输速率、最大下行传输速率、非连续接收DRX周期、所述终端同时处理的信道状态信息CSI报告的数量、所述终端同时处理的波束管理报告的数量、所述终端同时接收或处理的测量资源的数量、CSI报告相关的时延、波束管理报告相关的时延。
相关描述可参考所述目标节能模式中的描述，此处不再赘述。
需要说明的是，在实际应用中，所述N个节能模式中不同节能模式的确定参数可以相同，也可以不同。在不同节能模式包括相同项的确定参数的情况下，不同节能模式包括的相同项的确定参数的取值可相同，也可不同。
在方式二中，具体实现时，可通过将网络侧设备配置的N个节能模式分别编号，所述第一DCI可通过以下方式指示所述第一小区切换或激活所述目标节能模式：
1)通过所述第一DCI或所述第一DCI中节能模式指示域，来携带目标节能模式的标识或索引来指示终端激活或切换到目标节能模式上。
如：通过所述第一DCI或所述第一DCI中节能模式指示域，来指示目标节能模式的索引为1。该目标节能模式索引1对应网络配置的节能模式1，该节能模式1可以由以下参数确定：目标BWP、接收天线和接收通道的数。在终端接收到所述第一DCI后，切换到或激活到节能模式1，也就是切换到目标BWP。并按照节能模式1的配置来设置当前的接收天线数和接收通道数。
2)所述第一DCI可以既包含目标节能模式的索引又单独指示上述用来确定目标节能模式的部分参数。
如：通过所述第一DCI或所述第一DCI中节能模式指示域，来指示目标节能模式的索引为1，此外所述第一DCI还指示接收天线数和接收通道数。该目标节能模式索引1对应网络配置的节能模式1，该节能模式1由以下参数确定：目标BWP。在终端接收到所述第一DCI后，切换到或激活到节能模式1，也就是切换到目标BWP。再按照所述第一DCI中指示的接收天线数和接收通道数来设置当前的接收天线或接收通道数。
以下对所述第一DCI进行说明。
可选的，所述第一DCI的HARQ-ACK的反馈类型为动态码本类型，且所述终端通过第一子码本反馈所述第一DCI的HARQ-ACK。
上述第一子码本可以传输以下信息的HARQ-ACK反馈：

(2)在没有配置PDSCH-CodeBlockGroupTransmission的cell中，传输通过DCI format 1-1和DCI format1-0调度的PDSCH数据接收。
(3)不调度数据且包含辅小区休眠指示的DCI fomat 1_1。
可选的，所述第一DCI的HARQ-ACK的反馈比特的取值为肯定应答ACK。
可选的，所述第一DCI的HARQ-ACK反馈处理时延与第二DCI的HARQ-ACK反馈处理时延相同；其中，所述第二DCI为不调度数据且包含辅小区休眠指示的DCI。
具体实现时，一种可行的实施例为，UE接收所述第一DCI的最后一个符号后的N个符号之后，反馈所述第一DCI的HARQ-ACK信息。如果网络配置该UE启用PDSCH HARQ-ACK反馈处理类型2，则在不同的μ中，N的对应取值如下：在μ＝0的情况下，N＝5；在μ＝1的情况下，N＝5.5；在μ＝2的情况下，N＝11。否则，在μ＝0的情况下，N＝10；在μ＝10的情况下，N＝12；在μ＝2的情况下，N＝22；在μ＝3的情况下，N＝25(A UE is expected to provide HARQ-ACK information in response to a detection of a DCI format 1_1 indicating power saving mode without scheduling PDSCH after N symbols from the last symbol of a PDCCH providing the DCI formant 1_1.If processingType2Enabled of PDSCH-ServingCellConfig is set to enable for the serving cell with the PDCCH providing the DCI format 1_1,N＝5 for μ＝0,N＝5.5 for μ＝1,and N＝11 for μ＝2；otherwise,N＝10 for μ＝0,N＝12 for μ＝1,N＝22 for μ＝2,and N＝25 for μ＝3)。
需要说明的是，此处对于N的取值不作限制，即在不同μ的取值下，N的取值可以不同于上述示例中的N取值。
μ是所述第一DCI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的子载波间隔(SubCarrier Space，SCS)配置和所述第一DCI的混合自动重传请求应答(Hybrid Automatic Repeat Request  Acknowledgement，HARQ-ACK)信息所在的物理上行控制信道(Physical Uplink Control Channel，PUCCH)的SCS配置，两者之间的最小SCS(μ is the smallest SCS configuration between the SCS configuration of the PDCCH providing the DCI format 1_1 and the SCS configuration of a PUCCH with the HARQ-ACK information in response to the detection of the DCI format 1_1)。
另一实施例为，UE在接收所述第一DCI的最后一个符号所在的时隙后的T BWPswitchDelay+X个时隙之后，反馈所述第一DCI的HARQ-ACK信息。其中T BWPswitchDelay指的是BWP切换的时延，X指的是由于BWP切换而造成的中断。(A UE is expected to provide HARQ-ACK information in response to a DCI format 1-1 indicating SCell dormancy without scheduling PDSCH after T BWPswitchDelay+X slots from the slot containing the last symbol of a PDCCH providing the power saving mode without scheduling PDSCH,where T BWPswitchDelay and X are the BWP switching delay and interruption length)
不排除其他可能的所述第一DCI的HARQ-ACK反馈时延。
可选的，所述第一DCI中不包括辅小区休眠指示。也就是说，所述第一DCI为不调度数据，且不包括辅小区休眠指示的DCI。但需要说明的是，在某些实施方式中，所述第一DCI可以为不调度数据，且包括辅小区休眠指示的DCI。
可选的，所述第一DCI包括节能模式指示域，所述节能模式指示域用于指示所述终端的第一小区切换到或激活目标节能模式；其中，所述节能模式指示域为所述第一DCI中的新增域，或，所述节能模式指示域重用所述第一DCI的目标域。
为方便理解，具体说明如下：
情况一、所述节能模式指示域为所述第一DCI中的新增域。
情况二、所述节能模式指示域重用所述第一DCI的目标域。
在情况一中，所述节能模式指示域可以视为DCI中新增的用于指示节能模式切换或激活的域。在情况二中，所述节能模式指示域为DCI中现有的目标域，但可以重用目标域用于进行节能模式切换或激活的指示。
在情况二中，可选的，所述目标域包括以下至少一项：调制编码方案MCS 指示域、新数据指示NDI指示域、解调参考信号DMRS序列初始化指示域、冗余版本RV指示域、混合自动重传请求HARQ进程数指示域、天线端口指示域。
需要说明的是，上述目标域仅为示例，在其他实施方式中，所述目标域也可以为DCI中的其他域，如其他与调度不相关的域。
在图2对应的实施例中，可选的，所述接收第一下行控制信息DCI之后，所述方法还包括：
发送第二信息，所述第二信息用于指示所述终端是否接收到所述第一DCI。
具体实现时，所述第二信息可以为MAC CE，但不仅限于此。
这样，网络侧设备可以根据接收到的所述第二信息，确定终端是否接收到所述第一DCI，并根据确定结果执行相应的操作。如：若所述第二信息指示所述终端未接收到所述第一DCI，网络侧设备可以重新向所述终端下发所述第一DCI。
在图2对应的实施例中，可选的，所述接收第一下行控制信息DCI之前，所述方法还包括：
发送第三信息，所述第三信息指示所述终端具备接收所述第一DCI的能力。
具体实现时，所述第三信息可以用于指示所述终端是否具备接收所述第一DCI的能力。但只有在所述第三信息指示所述终端具备接收所述第一DCI的能力的情况下，终端才有可能接收到所述第一DCI，否则，网络侧可以向所述终端发送所述第一DCI，以节约信令开销。
在图2对应的实施例中，可选的，所述第一小区为以下任意一项：所述终端的全部服务小区、所述终端的任意一个或多个服务小区。
具体实现时，所述终端的任意一个或多个服务小区可以为：所述终端的主小区PCell、所述终端的全部(Secondary Cell，SCell)。
进一步地，所述终端的全部服务小区可以为所述终端激活的全部服务小区；所述终端的全部辅小区可以为所述终端激活的全部辅小区。
在所述第一小区包括多个小区的情况下，所述第一DCI的作用对象可以包括所述第一小区中的每个小区，此时，终端在执行所述第一DCI所指示的 行为时，可以将所述第一小区中的每个小区切换到所述目标节能模式，或，在所述第一小区中的每个小区激活所述目标节能模式。
可选的，所述第一DCI可以只在PCell上进行发送和接收，也可以在SCell上进行发送或接收。

为方便理解，示例说明如下：
实施例一：网络配置所述不调度数据且指示目标节能模式切换的DCI，在该DCI中的中配置参数包括目标BWP的ID以及所指示的目标节能模式的生效时延。
UE有一个服务小区，网络配置UE DRX机制。
网络配置UE不调度数据且包含指示目标节能模式切换的DCI 1-1，该DCI 中包括配置参数：目标BWP的ID(2比特)以及目标节能模式的生效时延(2比特)。
网络配置该DCI中包含的第二配置参数：节能模式生效时延为时延0＝1slot，时延1＝4slot。
所述DCI中指示目标节能模式的比特为“1001”表示激活BWP ID为2的BWP，且节能模式生效时延为时延1＝4slot。UE在收到该DCI后，在4 slots后将BWP切换到BWP2上。该BWP2为一个小带宽BWP，用户通过快速切换到该小带宽BWP上实现省电。
如图3所示，终端在t0接收到包含节能模式指示的非调度DCI，在t1开始执行BWP切换操作，所述切换操作用于将UE的服务小区切换到BWP2，在t2完成所述BWP切换，BWP2开始被激活。t0和t1之间间隔节能模式生效时延，即4 slots；t1和t2之间为BWP切换时延。
实施例二：网络配置多种节能模式和所述DCI，在DCI中的节能模式指示域中配置参数包括节能模式ID。通过DCI来激活某一种节能模式。
UE有一个服务小区，网络配置UE DRX机制。
网络配置5种节能模式，以及不调度数据且包含节能模式指示域的DCI 1-1，通过该DCI中的节能模式指示域动态指示激活某一种节能模式，该节能模式指示域比特大小为3比特。
5种节能模式，如下：
0)目标BWP为dormant BWP；
节能模式的生效时延为0；
发射天线或发射通道的数量＝2Tx；
最大下行多输入多输出MIMO层数＝1；
配置的搜索空间组的索引ID＝0；
1)目标BWP为最大带宽BWP；
节能模式的生效时延等于BWP switching delay；
发射天线或发射通道的数量＝4Tx；
最大下行多输入多输出MIMO层数＝1；
配置的搜索空间组的索引ID＝1；
2)目标BWP为first non-dormant BWP；
节能模式的生效时延为配置的最大重传次数*配置的重传最大时延；
发射天线或发射通道的数量＝2发送(Tx)；
最大下行多输入多输出MIMO层数＝2；
PDCCH监听周期＝5slot；
PDCCH监听偏移量＝0；
PDCCH监听持续时间＝2slot；
3)目标BWP为default BWP；
节能模式的生效时延为0；
发射天线或发射通道的数量＝2Tx；
接收天线或发射通道的数量＝1Tx；
最大下行多输入多输出MIMO层数＝1；
配置的搜索空间组的索引ID＝0；
4)目标BWP为最小带宽BWP；
节能模式的生效时延为0；
发射天线或发射通道的数量＝1Tx；
配置的搜索空间组的索引ID＝0；
如图4所示，终端在t0接收到包含节能模式指示的非调度DCI，该DCI中的节能模式指示域的比特为“100”表示激活节能模式3。UE在收到该DCI后立即将BWP切换到default BWP上，用1Tx来接收下行，并且按照搜索空间组0来进行相应的PDCCH的监听等。
实施例三：实施例一和二的结合，网络配置多种节能模式和所述DCI，在DCI的节能模式指示域中配置参数包括节能模式ID以及其他参数(除节能模式中的参数外)。DCI通过DCI来激活某一种节能模式以及其他参数。
如：终端接收到包含节能模式指示的非调度DCI，该DCI中的节能模式指示域的比特为“100”表示激活节能模式3，但DCI还包括节能模式指示域生效的时延，则终端在接收到该DCI之后，在节能模式指示域生效的时延将BWP切换到default BWP上，用1Tx来接收下行，并且按照搜索空间组0来进行相应的PDCCH的监听等。
本发明实施例设计了一种不调度数据且进行BWP切换指示的DCI，达到终端节能目的。
