为了更好的理解的本公开实施例的技术方案，首先介绍以下技术点：
一、关于跨时隙调度(cross-slot scheduling)：
NR R15标准支持跨时隙调度，跨时隙调度的原理是物理下行控制信道(Physical Downlink Control Channel，PDCCH)和PDCCH调度的物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)之间间隔N个时隙(slot)，其中PDSCH可配置K0个时隙，PUSCH可配置K2个时隙，且K0和K2是基站配置的，通过下行控制信息(Downlink Control Information，DCI)来指示，其中，K0表示PDCCH与PDCCH调度的PDSCH之间的时间间隔；K2表示PDCCH与PDCCH调度的PUSCH之间的时间间隔。
PDSCH的跨时隙调度的好处是UE不需要在PDCCH译码之前缓存PDSCH数据，UE在PDCCH译码之后再根据PDCCH的指示来接收PDSCH数据，UE可以选择性的分别开关射频(Radio Frequency，RF)和基带(Base Band，BB)模块，从而达到省电的效果。
二、关于UE的PDSCH处理时延：
NR支持具备不同PDSCH处理时延(N1)的两种UE能力，即PDSCH处理能力1和PDSCH处理能力2，分别对应UE processing capability 1和UE processing capability 2。PDSCH处理能力1属于基本UE能力，而PDSCH处理能力2的UE其PDSCH处理时延更短。
三、关于UE的PUSCH准备时延：
NR支持具备不同PUSCH准备时延(N2)的两种UE能力，即PUSCH时延能力1和PUSCH时延能力2，分别对应UE processing capability 1和UE processing capability 2。PUSCH时延能力1属于基本UE能力，而PUSCH时延能力2的UE其PUSCH准备时延更短。
四、关于省电相关的参数的介绍：
NR R15标准中与UE省电相关的参数包括：
终端发射天线数；
终端接收天线数；
同时激活的上行分量载波(Component Carrier，CC)数；
同时激活的下行CC数；

PDSCH处理时延(N1)或PUSCH准备时延(N2)；
终端接收信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)CSI-RS配置到上报CSI的时延或者终端测量 CSI-RS到上报CSI的时延；
下行多输入多输出(MultipleInput Multiple Output，MIMO)层(layer)数；
上行MIMO layer数；
PDCCH监听(monitoring)周期或PDCCH监听偏移量(offset)或PDCCH监听持续时间(duration)；
部分带宽(Band Width Part，BWP)的带宽或BWP的标识(Identity，ID)；
双连接(Dual Connectivity，DC)或非双连接(non-DC)；
最大上行速率或最大下行速率；
同时处理的CSI报告(report)或波束管理报告(beam management report)的数量；
同时接收或处理测量资源的数量；以及
CSI report相关的时延beam management report相关的时延。
在本公开实施例中，节能模式(power saving mode)可以包括：节能模式1、节能模式2、节能模式3、节能模式4、……等，其中每种节能模式对应的参数和该参数的取值可以相同也可以不同。可以理解的是，在本公开实施例中对节能模式对应的参数和该参数的取值并不做具体限定。
在本公开实施例中，节能等级(power saving level)可以包括：节能等级1、节能等级2、节能等级3、节能等级4、……等，其中每种节能等级对应的参数和该参数的取值可以相同也可以不同。可以理解的是，在本公开实施例中对节能等级对应的参数和该参数的取值并不做具体限定。

实施例1：有唤醒信号(Wake-up signal，WUS)的连接态的非连续性接收(Connected Discontinuous Reception，CDRX)。
场景：WUS位于CDRX的持续时间定时器(onduration timer)之前或者onduration timer内，UE会检测WUS，WUS指示UE是否监听onduration timer里的PDCCH；根据WUS检测结果，UE会监听onduration timer里的PDCCH或不监听onduration timer里的PDCCH。
示例性地，CDRX时，UE通过第一节能模式接收WUS，如果WUS指示UE需要监听onduration timer内的PDCCH，触发UE切换到第二节能模式；否则，不切换到第二节能模式(即，维持第一节能模式)。
进一步地，可选地，UE切换到第二节能模式之后，向gNB上报该UE已切换到第二节能模式。
实施例2：没有WUS的CDRX。
场景：CDRX的onduration timer期间，UE会监听PDCCH，如果收 到PDCCH承载的调度信息，会启动连接态的非连续性接收-非激活定时器(CDRX-Inactivity timer)并持续监听PDCCH；否则，UE会在onduration timer之后进入不连续性接收(Discontinuous Reception，DRX)关闭(OFF)。
示例性地，在onduration timer期间且CDRX-Inactivity timer没启动，UE工作在第一节能模式；如果CDRX-Inactivity timer启动，触发UE切换到第二节能模式；否则，不切换到第二节能模式。
进一步地，可选地，UE切换到第二节能模式之后，向gNB上报该UE已切换到第二节能模式。
实施例3：默认BWP(default BWP)。

示例性地，在RRC激活态，UE工作在第一节能模式时，UE在active BWP上在一定的timer内没有收到PDCCH承载的调度信息，则UE切换到default BWP，同时触发UE切换到第二节能模式，例如第二节能模式具有更少的天线数，比如2个接收天线(2收(2Rx))，假设UE工作在active BWP的第一节能模式是4个接收天线(4收(4Rx))；否则，维持第一节能模式。
实施例4：RRC空闲模式或激活模式中的寻呼(paging in RRC idle/active mode)

示例性地，UE通过第一节能模式接收寻呼(Paging)消息，如果寻呼消息指示系统寻呼该UE，则触发UE切换到第二节能模式接收后续信息；否则，维持第一节能模式。
示例性地，UE通过第一节能模式接收Paging消息，如果寻呼消息指示系统寻呼该UE且寻呼原因不是系统信息更新，则触发UE切换到第二节能模式；否则，维持第一节能模式。
实施例5：有WUS的RRC空闲模式或激活模式中的寻呼(paging in RRC idle/active mode with WUS)。
场景：RRC idle/active mode时，UE每隔一段时间(例如每个寻呼周期(paging cycle))监听位于寻呼时机(Paging Occasion，PO)之前的WUS，WUS指示UE是否需要监听对应的paging消息。
示例性地，UE通过第一节能模式接收PO之前的WUS，如果WUS指示UE需要监听对应的paging消息，触发UE切换到第二节能模式以接收paging消息，否则，不切换到第二节能模式。
示例性地，UE通过第一节能模式接收PO之前的WUS，如果WUS指示UE需要监听对应的paging消息，UE通过第一节能模式接收paging消息，且寻呼消息与UE相关(即，paging消息指示系统寻呼该UE)，触发UE切换到第二节能模式接收后续信息；否则，维持第一节能模式。
示例性地，UE通过第一节能模式接收PO之前的WUS，如果WUS指示UE需要监听对应的paging消息，UE通过第一节能模式接收paging消息，如果paging消息与UE相关且寻呼原因不是系统信息更新，触发UE切换到第二节能模式接收后续信息；否则，维持第一节能模式。
实施例6：基于计时器(timer based)。
示例性地，UE在RRC connected状态且配置了第二节能模式，如果在预设的或基站配置的定时器(timer)内没有收到PDCCH承载的调度信息，则触发UE切换到第一节能模式；否则，维持第二节能模式。
实施例7：状态触发(state triggered)。
示例性地，UE在RRC connected状态且配置了第二节能模式，如果UE进入空闲(idle)态或者非激活(inactive)态，则触发UE切换到第一节能模式；否则，维持第二节能模式。
示例性地，UE在idle或者inactive态为第一节能模式，进入RRC连接(RRC connected)态，则触发UE切换到第二节能模式；否则，维持第一节能模式。
实施例8：新空口未授权(NR Unlicensed，NRU)系统的初始信号(initial signal)。
示例性地，NRU系统中，基站配置了第一节能模式或者UE工作在第一节能模式，如果UE检测到initial signal，则触发UE切换到第二节 能模式；如果UE未检测到initial signal，则维持第一节能模式。
实施例9：UE上行发送(Random Access Channel，RACH)承载的信息。
示例性地，基站为UE配置了第一节能模式或者UE工作在第一节能模式，在UE发送RACH承载的信息之后或者UE确定要发送RACH承载的信息，UE切换到第二节能模式。否则，维持第一节能模式。
实施例10：UE发送调度请求(Scheduling Request，SR)。
示例性地，基站为UE配置了第一节能模式或者UE工作在第一节能模式，在UE发送SR之后或者UE确定要发送SR，UE切换到第二节能模式；否则，维持第一节能模式。
