本申请实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,并不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本公开实施例提供了一种节能指示方法及装置。其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图1所示,为本公开实施例提供的一种节能指示方法,包括:
步骤201,终端接收节能信令;
步骤202,所述终端根据所述节能信令确定休眠窗口,并在所述休眠窗口内进入休眠态;
其中,所述休眠窗口的长度与第一对象的传输参数和/或节能配置相关。
如此,终端按照步骤201-202,在接收节能信令后,能够基于该节能信令,确定休眠窗口,并在该休眠窗口内进入休眠态,故,终端的节能不再具有ACK反馈时延,而且由于其中休眠窗口的长度与第一对象的传输参数相关,和/或,休眠窗口的长度与第一对象的节能配置相关,还能够针对第一对象进行调整,实现了更有效地节能。
需要说明的是,本公开实施例中,终端在休眠窗口进入休眠,即终端在休眠窗口进入休眠态(休眠状态)。
可选地,所述传输参数可以为第一对象的发送或接收窗口。
可选地,所述第一对象包括以下一项或多项:
物理下行共享信道(Physical Downlink Shared Channel,PDSCH);
物理上行共享信道(Physical Uplink Shared Channel,PUSCH);
半静态调度(Semi-Persistent Scheduling,SPS);
配置授权(Configured Grant,CG);
物理下行控制信道(Physical Downlink Control CHannel,PDCCH);
物理上行控制信道(Physical Uplink Control CHannel,PUCCH)。
可选地,所述第一对象是对应第一业务的传输。
这里,第一业务可以是特定的一种或多种业务。
作为一种实施方式,第一业务是扩展现实(Extended Reality,XR)业务。
作为一种实施方式,网络侧设备对于第一业务(如XR业务),能够基于业务或业务流子数据流传输特性配置半静态配置至少一个非连续接收(Discontinuous Reception,DRX)配置,一个DRX配置下多套参数,如此,
至少一个DRX配置,一个DRX配置下多套参数都可以是第一对象的传输参数。
作为一种实施方式,网络侧设备对于第一业务(如XR业务),能够配置第一业务专属的PDCCH监听窗口(如XR专属PDCCH监听窗口(XR-Specific PDCCH Monitoring Window,XR-Specific PMW)),如此,第一对象的传输参数可以是第一业务专属的PDCCH监听窗口的相关传输。该第一业务专属的PDCCH监听窗口也可理解为第一对象的窗口。
作为一种实施方式,网络侧设备对于第一业务(如XR业务),能够直接配置业务专属的节能配置,来确定休眠窗口的长度。
当然,第一对象的传输参数、第一对象的节能配置可以由网络侧设备配置,也可以预先定义。
可选地,所述终端在休眠窗口内进入休眠态,包括:
所述终端基于第一配置信息,在所述休眠窗口内执行以下一项或多项:
停止监听PDCCH;
停止至少一个网络侧配置的定时器;
跳过SPS资源的接收和/或发送;
跳过CG资源的接收和/或发送;
跳过确认ACK或否定(Negative Acknowledgement,NACK)的反馈;
不上报参考信号的测量。
即,终端在休眠窗口内将按照第一配置信息执行上述行为中的至少一项。如此,终端在休眠状态同样执行上述行为中的至少一项。
其中,不监听PDCCH可以是在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity Timer。
其中,跳过SPS资源的接收和/或发送,还可以理解为跳过SPS时机(occasion(s))。
其中,跳过CG资源的接收和/或发送,还可以理解为跳过CG(occasion(s))。
其中,跳过ACK或NACK的反馈,还可以理解为过ACK或NACK反馈时机。
其中,网络侧配置的定时器,包括但不限于drx-OndurationTimer,
drx-InactivityTimer。故,停止至少一个网络侧配置的定时器,可以是停止drx-OndurationTimer,停止drx-InactivityTimer等。这里,第一配置信息可以是预先定义的,或者是网络侧设备配置的。具体的,该第一配置信息是针对第一业务的。
作为一种实施方式,所述参考信号包括信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),追踪参考信号(Tracking Reference Signal,TRS)等。
此外,基于第一配置信息,终端在休眠窗口内不测量参考信号。
可选地,所述节能信令为动态信令,所述节能信令包括以下至少一项:
业务专属下行控制信息(Downlink control Information,DCI);
用于调度PDSCH的DCI;
用于调度PUSCH的DCI;
用于调度PDCCH的DCI;
用于调度PUCCH的DCI;
不用于调度PDSCH的DCI;
不用于调度PUSCH的DCI;
不用于调度PDCCH的DCI;
不用于调度PUCCH的DCI;
媒体接入控制控制MAC层信令。
这里,业务专属DCI即专用于指示终端节能的信令。用于调度的DCI,不仅可以用于指示终端节能,还能够用于调度数据传输。不用于调度的DCI,不仅可以用于指示终端节能,还能够用于其它目的。而MAC层信令也能够用于指示终端节能。
其中,MAC层信令可以是MAC-CE信令,但此时该MAC-CE信令作为上述节能信令,无需等待ACK反馈,终端能够直接在休眠窗口内进入休眠。
当然,节能信令的实现包括但不限于上述信令,在此不再一一列举。
该实施例中,对于业务专属DCI,还预先定义或网络侧设备配置了特定的接收配置信息(即信令接收参数)。可选地,所述节能信令为业务专属DCI的情况下,所述节能信令的接收配置信息包括以下一项或多项:
有效载荷大小(payload size);
控制资源集CORESET;
搜索空间(Search Space,SS);
无线网络临时标识(Radio Network Temporary Identity,RNTI)。
如此,终端在接收该节能信令时,会按照其专属的接收配置信息进行接收。
作为一种实施方式,控制资源集CORESET/SS包括:专属的PDCCH监听周期,专属的PDCCH监听时域持续时间。
作为一种实施方式,RNTI可以是休眠RNTI(Go-To-Sleep_RNTI,GTS_RNTI)。
可选地,所述休眠窗口的起始时间基于以下一项或多项确定:
所述节能信令的接收时刻;
所述节能信令指示的调度信息成功接收后反馈ACK的时刻;
所述节能信令指示的调度信息的接收时刻。
也就是说,终端在接收到节能信令后,能够基于该节能信令确定休眠窗口的起始时间。
作为一种实施方式,若休眠窗口的起始时间基于节能信令的接收时刻确定,也就是休眠窗口起始时间和此节能信令的接收时刻相关联,例如,终端接收到该节能信令,立即进入休眠;若休眠窗口的起始时间基于节能信令指示的调度信息成功接收后反馈ACK的时刻确定,也就是休眠窗口起始时间和此节能信令指示的调度信息成功接收后反馈ACK的时刻相关联,例如,终端成功接收到此动态信令调度的数据后,反馈ACK的时刻进入休眠;若休眠窗口的起始时间基于节能信令指示的调度信息的接收时刻确定,也就是休眠窗口起始时间和此节能信令指示的调度信息的接收时刻相关联,例如,终端接收此动态信令调度的数据,在完成该数据接收的时刻进入休眠。
当然,所述休眠窗口的起始时间还可结合节能信令,以及预先定义或网络侧设备配置的相关信息共同确定。例如,网络侧设备配置休眠窗口的起始偏移量,则终端接收到该节能信令后,需要等待一段时间(该段时间的长度等于该起始偏移量)进入休眠。
可选地,所述休眠窗口的终止时间基于第二配置信息确定,所述第二配置信息包括以下一项或多项:
至少一个非连续接收配置参数;
第一业务的专属接收窗口参数,所述第一业务与所述第一对象对应;
休眠持续时间;
休眠终止参考时间;
休眠期间监听重传PDCCH的位置。
这里,第二配置信息是预先定义或网络侧设备配置的。具体的,该第一配置信息是针对第一业务的。
其中,至少一个非连续接收配置参数可以是:多套(组)DRX配置的参数,和/或,一套(组)DRX配置下的多个参数,如一个DRX周期(cycle)配置多个非连续接收起始偏移(drx-StartOffset)。
其中,第一业务的专属接收窗口是基于特定业务或业务子数据流传输特性配置专属层一信号接收窗口,如第一业务为XR时的XR-Specific PMW。
其中,休眠持续时间可以基于业务传输特性如周期、时延抖动配置。
其中,休眠终止参考时间包括:休眠终止候选位置,和/或,用于确定休眠终止时间的位置。
其中,休眠期间监听重传PDCCH的位置,即终端在休眠窗口中,监听重传PDCCH的位置。
可选地,所述节能信令的第一指示域用于承载休眠指示;其中,
所述第一指示域为休眠专用指示域;或者,
所述第一指示域为DCI中指定的指示域。
这里,休眠指示即用于指示终端进入休眠状态。
也就是说,对于节能信令,可以使用休眠专用指示域来承载休眠指示;指定的指示域是已有指示域,即也可以复用其它指示域(已有的指示域)来承载休眠指示。当然,指定的指示域不限于DCI,即,节能信令不为DCI时,也可以复用已有指示域承载休眠指示。
作为一种实施方式,在复用其它指示域来承载休眠指示的情况下,通过该指示域的保留值(reserve value)指示休眠。
可选地,所述第一指示域为PDCCH监听适应指示域(PDCCH monitoring adaptation indication),所述第一指示域通过保留值指示休眠。
其中,PDCCH监听适应指示域可以用于承载跳过PDCCH监听指示,或搜索空间集组(Search Space Set Group,SSSG)转换指示。
作为一种实施方式,业务专属DCI中包括休眠专用指示域和/或PDCCH监听适应指示域,其中,休眠专用指示域承载休眠指示。
作为一种实施方式,用于调度的DCI增加休眠专用指示域,和/或已有的PDCCH监听适应指示域的reserve value指示休眠。
当然,对于指示信令的不同实现,通过复用的指示域于承载休眠指示时,除PDCCH监听适应指示域之外,第一指示域还可以是其它指示域,例如不用于调度的DCI(如DCI 2_6),通过已有的辅小区休眠指示域(scell dormancy indication)承载所述休眠指示;4)3)采用PDSCH承载的MAC-CE信令,增加休眠专用指示域承载休眠指示,其中,休眠专用指示域的比特长度是预定义的。
此外,在网络侧设备配置上述第一配置信息和/或第二配置信息的情况下,网络侧设备还可以通过第一指示域来指示第一配置信息和/或第二配置信息,以达到节省信令开销的目的。
可选地,在所述第一指示域还用于指示第一配置信息和/或第二配置信息的情况下,所述第一指示域的比特长度由所述第一配置信息和/或所述第二配置信息的数量确定。
以第一配置信息包括四种为例,第一指示域需要2比特长度,通过这2比特的值来指示使用的第一配置信息的序号,如“01”指示使用序号2的第一配置信息;或者,第一指示域需要4比特长度,通过与第一配置信息的序号对应的比特来指示使用的第一配置信息,如“0100”指示使用序号3的第一配置信息。
当然,第一指示域的比特长度也可是预先定义的,如预先定义第一指示域的比特长度为1。
可选地,所述方法还包括:
所述终端根据协议预定义的规则,在存在调度数据接收错误,且重传未
完成的情况下,在所述休眠窗口内终止或暂停休眠,并执行以下至少一项:
在搜索空间SS上监听重传和/或初传PDCCH;

测量或上报参考信号;
在配置授权CG上传输数据和/或接收半持续调度SPS资源上的数据;
或者,

在搜索空间SS上监听重传和/或初传PDCCH;
开启非连续接收去激活定时器drx-Inactivity Timer;
测量或上报参考信号;
在CG上传输数据和/或接收SPS资源上的数据。
其中,第三配置信息是预定义或预先配置的信息。
即,终端根据协议预定义的规则,在存在调度数据接收错误,且重传未完成的情况,例如终端需要在休眠期间监听重传调度信息,在所述休眠窗口内终止或暂停休眠,并执行以下至少一项:在SS上监听重传和/或初传PDCCH;开启drx-Inactivity Timer;测量或上报参考信号;在CG上传输数据和/或接收SPS资源上的数据。
或者,终端能够通过确定所述节能配置中的第三配置信息和/或预先定义或网络侧设备配置的重传PDCCH配置信息,根据该第三配置信息和/或重传PDCCH配置信息,在休眠窗口内终止或暂停休眠,并执行以下至少一项:在搜索空间SS上监听重传和/或初传PDCCH;开启drx-Inactivity Timer;测量或上报参考信号;在CG上传输数据和/或接收SPS资源上的数据。可选的,在存在调度数据接收错误,且重传为完成的情况下,例如终端需要在休眠期间监听重传调度信息,终端确定重传PDCCH配置信息和/或节能配置中的第三配置信息,以在休眠窗口内终止或暂停休眠,并执行上述至少一项。

听重传PDCCH。
可选地,所述在所述休眠窗口内终止或暂停休眠,包括:
所述终端基于第一长度,在所述休眠窗口内终止或暂停休眠;
其中,所述第一长度是协议预定义或所述第三配置信息中的所述休眠窗口的长度门限。
该实施例中,休眠也可理解为跳过步骤(skipping step),即,第一长度也可理解为skipping step的门限值。其中,终端基于第一长度,在所述休眠窗口内终止或暂停休眠,可以是终端确定休眠窗口的长度,在所确定的休眠窗口的长度大于该第一长度,且在休眠窗口内存在调度数据接收错误,且重传未完成的情况下,终止或恢复休眠。例如,终端基于第二配置信息确定休眠窗口的长度,所确定的休眠窗口的长度大于第一长度,当终端在休眠窗口内接收到NACK后,恢复PDCCH监听。
当然,若终端所确定的休眠窗口的长度不大于该第一长度,即使在休眠窗口内存在调度数据接收错误,且重传未完成(如收到NACK),也继续休眠直至休眠窗口的终止时间。
作为一种实施方式,协议预定义规则包括确定的休眠窗口的长度大于所述第一长度。或者,作为一种实施方式,第三配置信息包括所述第一长度,所述第三配置信息可以是协议预定义的信息,或者是RRC信令预配置的信息。
另一方面,第一配置信息还可以配置终端在休眠窗口监听重传PDCCH配置信息,如此,终端能够通过监听确定重传PDCCH配置信息,进而在休眠窗口内按照该重传PDCCH配置信息监听重传PDCCH。当然,若未配置终端在休眠窗口监听重传PDCCH配置信息,则终端在休眠窗口结束后监听重传PDCCH。
可选地,所述终止或暂停休眠的起始时间包括如下任一项:
终端反馈NACK所在的时域位置;
终端反馈NACK所在的时域位置后再经过非连续接收-下行HARQ往返等待定时器(drx-HARQ-RTT-TimerDL)的时间;
终端反馈NACK的时间或终端反馈NACK所在的时域位置之后的第一时域位置,所述第一时域位置基于网络侧设备接收上行控制信道的处理时间确定;
终端反馈NACK的时间或终端反馈NACK所在的时域位置之后的第二时域位置,所述第二时域位置基于网络侧设备接收上行数据信道的处理时间确
定。
可选地,所述暂停休眠的终止时间包括以下任一项:
非连续接收-下行重传定时器(drx-RetransmissionTimerDL)到期;
终端正确接收重传数据且反馈ACK时域位置。
可选地,该实施例中,若终端终止休眠,该终端则持续进入激活(active)状态。如此,该实施例中,在终端需要在休眠期间监听重传调度信息时,终端在休眠窗口中能够从休眠状态进入正常数据接收状态(也可理解为激活状态),直到终端成功接收到重传调度数据或重传次数达到最大重传次数。此时,如果终端还处于休眠窗口内,则终端可以继续进入休眠状态直到休眠窗口结束,或者终端可以继续保持激活状态,可以进行正常数据传输。
当然,如果终端不需要在休眠窗口监听重传调度信息,终端在成功接收到休眠指示信息后立刻进入休眠状态,直到休眠窗口终止时间。
可选地,重传PDCCH配置信息能够用于确定重传PDCCH监听时机。
其中,重传PDCCH配置信息包括重传PDCCH监听的起始时间和持续时间。
需要说明的是,网络侧设备配置的重传PDCCH配置信息也可以通过节能信令指示,同第一配置信息、第二配置信息,在此不再赘述。当然,该实施例中,网络侧设备的其它配置也可通过节能信令或其它信令指示。
下面,结合具体场景说明本公开实施例的具体应用:
场景一、基站根据传输业务特性,配置至少一组DRX配置(每组DRX配置下的参数包括有独立的DRX cycle,drx-StartOffset,drx-OndurationTimer,drx-InactivityTimer等),匹配第一业务达到以及传输性能要求。
在该场景中,网络侧设备确定节能信令(如业务专属DCI),并根据业务传输情况下发该信令。当然,网络侧设备还可以配置第一配置信息、第二配置信息、重传PDCCH配置信息中的一项或多项。
如此,终端接收该节能信令后,基于休眠窗口的起始时间与节能信令的关联,立即进入休眠状态;或成功接收到该节能信令调度数据且反馈ACK后,进入休眠状态。
休眠窗口的终止时间基于第二配置信息确定。
终端在休眠窗口执行以下一项或多项(也可以理解为休眠状态中包括至
少如下之一的行为):
终端在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity Timer;
不测量参考信号;
跳过SPS/CG occasion(s);
跳过ACK/NACK反馈时机;
监听重传PDCCH的配置信息。
如果在终端接收到节能信令之前,存在调度数据接收错误,且重传为完成的情况,终端在休眠窗口执行监听重传PDCCH的配置信息,可以通过监听到的重传PDCCH配置信息,在休眠状态监听重传PDCCH。其中,重传PDCCH的监听时机由重传PDCCH配置信息确定。
当然,若未配置重传PDCCH配置信息,则在休眠窗口结束后监听重传PDCCH。
例如,如图2所示,网络侧为终端配置了三组DRX,DRX1~DRX3匹配第一业务(如XR业务)传输的特性(包括:XR数据的到达周期,网络的时延抖动)。
数据包在DRX1的drx-OndurationTimer超时前传输完成且传输正确,网络侧设备下发节能信令指示终端进入休眠状态,终端成功接收到此节能信令立马进入休眠状态。
其中,网络侧设备配置或预先定义休眠窗口的终止时间由DRX1~DRX3确定(也可以是DRX1~3中一个或两个),故,如果网络侧设备配置或预先定义终端休眠窗口的终止时间是下一个最早的drx-StartOffset关联的DRX配置的起始时刻(也就是DRX2的DRX ON duration起始时刻),则如图2所示,休眠窗口为接收到节能信令的时刻到DRX2的DRX ONduration起始时刻,也就是终端接收到指令后进入休眠状态一直持续到DRX2的DRX ONduration起始时刻。
其中,终端进入休眠状态期间有SPS/CG,ACK/NACK反馈时机资源配置,参考信号测量位置,根据第一配置信息来决定是否跳过SPS/CG传输资源以及ACK/NACK反馈时机,是否进行参考信号测量。
场景二、基站根据传输业务特性,在至少一组DRX下配置多个参数(如,在一个DRX cycle中配置多个drx-StartOffset),匹配第一业务达到以及传输性能要求。
在该场景中,网络侧设备确定节能信令(如业务专属DCI),并根据业务传输情况下发该信令。当然,网络侧设备还可以配置第一配置信息、第二配置信息、重传PDCCH配置信息中的一项或多项。
如此,终端接收该节能信令后,基于休眠窗口的起始时间与节能信令的关联,立即进入休眠状态;或成功接收到该节能信令调度数据且反馈ACK后,进入休眠状态。
休眠窗口的终止时间基于第二配置信息确定。
终端在休眠窗口执行以下一项或多项(也可以理解为休眠状态中包括至少如下之一的行为):
终端在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity Timer;
不测量参考信号;
跳过SPS/CG occasion(s);
跳过ACK/NACK反馈时机;
监听重传PDCCH的配置信息。
如果在终端接收到节能信令之前,存在调度数据接收错误,且重传为完成的情况,终端在休眠窗口执行监听重传PDCCH的配置信息,可以通过监听到的重传PDCCH配置信息,在休眠状态监听重传PDCCH。其中,重传PDCCH的监听时机由重传PDCCH配置信息确定。
当然,若未配置重传PDCCH配置信息,则在休眠窗口结束后监听重传PDCCH。
例如,如图3所示,网络侧设备为终端配置了对应第一业务(如XR业务)的一组DRX的三个startoffset,即startoffset={0,17,33}ms。数据包在第一个DRX Onduration(即startoffset=0ms)期间成功完成一个XR数据包的传输,网络侧设备下发节能信令,终端接收到该节能指令立即进入休眠状态。网络侧设备配置或预先定义休眠窗口的终止时间由这三个startoffset对应的
DRX窗口(如DRX Onduration)确定,如果网络侧设备配置或预先定义终端休眠窗口的终止时间与startoffset=17ms关联,则如图3所示,休眠窗口为接收到节能信令的时刻到下一个最早的DRX Onduration(即startoffset=17ms)的起始时间,也就是终端接收到指令后进入休眠状态一直持续到下一个最早的DRX Onduration(即startoffset=17ms)的起始时间
又或者,如图4所示,网络侧设备为终端配置了对应第一业务(如XR业务)的一组DRX的三个startoffset,即startoffset={0,17,33}ms。数据包在第一个DRX Onduration(即startoffset=0ms)期间成功完成一个XR数据包的传输,网络侧设备下发节能信令,终端接收到该节能指令立即进入休眠状态。网络侧设备配置或预先定义休眠窗口的终止时间由这三个startoffset对应的DRX Onduration确定,如果网络侧设备配置或预先定义终端休眠窗口的终止时间与startoffset=33ms关联,则如图4所示,休眠窗口为接收到节能信令的时刻到下一个最早的DRX Onduration(即startoffset=33ms)的起始时间,也就是终端接收到指令后进入休眠状态一直持续到下一个最早的DRX Onduration(即startoffset=33ms)的起始时间。
场景三、基站根据传输业务特性,为传输特定业务和/或业务子数据流配置独立的PDCCH监听窗口,如对于第一业务为XR业务,配置XR-Specific PMW。如果此时网络侧设备配置了DRX,在DRX OFF期终端也可以根据监听窗口的配置周期性监听调度PDCCH。
在该场景中,网络侧设备确定节能信令(如业务专属DCI),并根据业务传输情况下发该信令。当然,网络侧设备还可以配置第一配置信息、第二配置信息、重传PDCCH配置信息中的一项或多项。
如此,终端接收该节能信令后,基于休眠窗口的起始时间与节能信令的关联,立即进入休眠状态;或成功接收到该节能信令调度数据且反馈ACK后,进入休眠状态。
休眠窗口的终止时间基于第二配置信息确定。
终端在休眠窗口执行以下一项或多项(也可以理解为休眠状态中包括至少如下之一的行为):
终端在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity
Timer;
不测量参考信号;
跳过SPS/CG occasion(s);
跳过ACK/NACK反馈时机;
监听重传PDCCH的配置信息。
如果在终端接收到节能信令之前,存在调度数据接收错误,且重传为完成的情况,终端在休眠窗口执行监听重传PDCCH的配置信息,可以通过监听到的重传PDCCH配置信息,在休眠状态监听重传PDCCH。其中,重传PDCCH的监听时机由重传PDCCH配置信息确定。
当然,若未配置重传PDCCH配置信息,则在休眠窗口结束后监听重传PDCCH。
例如,如图5所示,网络侧设备为终端配置DRX(DRX cycle=160ms,startoffset=0ms)和XR-Specific PMW(监听周期=16ms,监听持续时长=12ms),终端在DRX OFF期间仍然基于XR-Specific PMW的配置监听PDCCH,网络侧设备配置或预先定义休眠窗口终止时间基于XR-Specific PMW确定,数据包在第一个PMW的监听持续时间内成功完成一个XR数据包的传输,网络侧下发一个节能指令,则休眠窗口为终端接收到节能指令的时间到下一个PMW的起始时间,也就是终端接收到指令后进入休眠状态一直持续到下一个PMW的起始时间。
场景四、基站根据传输业务特性,不为服务的终端配置DRX,基站下的终端处于Always ON状态(根据SS的配置监听PDCCH)。
在该场景中,网络侧设备确定节能信令(如业务专属DCI),并根据业务传输情况下发该信令。当然,网络侧设备还可以配置第一配置信息、第二配置信息、重传PDCCH配置信息中的一项或多项。
如此,终端接收该节能信令后,基于休眠窗口的起始时间与节能信令的关联,立即进入休眠状态;或成功接收到该节能信令调度数据且反馈ACK后,进入休眠状态。
休眠窗口的终止时间基于第二配置信息确定,即第二配置信息包括与第一业务对应的传输的节能配置,如休眠持续时间或休眠终止参考时间等。
终端在休眠窗口执行以下一项或多项(也可以理解为休眠状态中包括至少如下之一的行为):
终端在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity Timer;
不测量参考信号;
跳过SPS/CG occasion(s);
跳过ACK/NACK反馈时机;
监听重传PDCCH的配置信息。

当然,若未配置重传PDCCH配置信息,则在休眠窗口结束后监听重传PDCCH。
场景五、网络侧设备确定节能信令(如业务专属DCI),并根据业务传输情况下发该信令。当然,网络侧设备还可以配置第一配置信息、第二配置信息、重传PDCCH配置信息、第三配置信息中的一项或多项。
如此,终端接收该节能信令后,基于休眠窗口的起始时间与节能信令的关联,立即进入休眠状态;或成功接收到该节能信令调度数据且反馈ACK后,进入休眠状态。
休眠窗口的终止时间基于第二配置信息确定。
终端在休眠窗口执行以下一项或多项(也可以理解为休眠状态中执行至少如下之一的行为):
终端在至少一个DRX上停止drx-onDuartion Timer和/或drx-Inactivity Timer;
不测量参考信号;
跳过SPS/CG occasion(s);
跳过ACK/NACK反馈时机;
监听重传PDCCH的配置信息。

终端反馈NACK的时间和/或终端反馈NACK所在的时域位置之后的第一时域位置,如t1+t3,t3等于基站接收上行控制信道的处理时间;
终端反馈NACK的时间和/或终端反馈NACK所在的时域位置之后的第二时域位置,如t1+t4,t4等于基站接收上行数据信道的处理时间。
其中,如果终端暂停休眠窗口,则暂停的终止时间可以是以下任一项:
drx-RetransmissionTimerDL到期;
终端正确接收重传数据且反馈ACK的时域位置。
另外,如果终端终止休眠,则该终端持续进入active状态。
