Description
本申请涉及无线通信技术领域,特别涉及一种定时器状态更改方法、装置、终端及存储介质。
在第五代移动通信(5th-Generation,5G)网络中,基于节能的考虑,引入了DRX(Discontinuous Reception,非连续接收)机制。
具有DRX机制的UE,可以通过DRX定时器触发UE在某些时间段内进入睡眠状态(Sleep Mode),不监听PDCCH子帧,当通过DRX定时器确定终端处于需要监听的时间段时,则将UE从睡眠状态唤醒,从而减小UE对PDCCH进行监听所产生的功率消耗。
上述方案中,UE可能在不需要监听PDCCH的时间段内被DRX定时器唤醒,导致不必要的功率消耗。
发明内容
本申请实施例提供了一种定时器状态更改方法、装置、终端及存储介质。所述技术方案如下:
一方面,本申请实施例提供了一种定时器状态更改方法,所述方法包括:

又一方面,本申请实施例提供了一种定时器状态更改方法,所述方法包括:

再一方面,本申请实施例提供了一种终端,所述终端包括处理器、存储器和收发器,所述存储器存储有计算机程序,所述计算机程序用于被所述处理器执行,以实现上述定时器状态更改方法。
又一方面,本申请实施例还提供了一种计算机可读存储介质,所述存储介质中存储有计算机程序,所述计算机程序由处理器加载并执行以实现上述定时器状态更改方法。

本申请实施例提供的技术方案可以带来如下有益效果:
当终端的第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL运行时,且终端的传输过程满足第一条件时,网络侧设备在上行传输发生的一段时间内可能不会向终端下发PDCCH,终端此时不需要对PDCCH进行监听,因此终端可以更改第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,比如通过停止或重启等方式来合理延长RTT的下次超时时间,减少了终端由于DRX-HARQ-RTT-Timer超时所导致的不必要的监听,减小了终端的功率消耗,节省了终端的电量。

在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
本申请实施例中,“预定义”可以通过在设备(例如,包括终端设备和网络侧设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的。
图1示出了本申请一个实施例提供的通信系统的网络架构的示意图。该网络架构可以包括:终端10、基站20以及核心网30。
终端10的数量通常为多个,每一个基站20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,本申请实施例中,上面提到的设备统称为终端。
基站20是一种部署在接入网中用以为终端20提供无线通信功能的装置。基站20可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在5G新空口(New Radio,NR)系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端20提供无线通信功能的装置统称为基站。
在本申请实施例中,基站20中可以包含至少两个基站,该至少两个基站分别用于覆盖基站各自对应的小区。
核心网(Core Network,CN)30主要是提供用户连接、对用户的管理以及对业务完成承载,作为承载网络提供到外部网络的接口。用户连接的建立包括移动性管理、呼叫管理、交换/路由、录音通知(结合智能网业务完成到智能网外围设备的连接关系)等功能。
可选的,图1中未示出的是,上述网络架构还包括其它网络侧设备,比如:中心控制节点(Central Network Control,CNC)、会话管理功能(Session Management Function,SMF)或者用户面功能(User Plane Function,UPF)设备等等。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统,但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统。
当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此3GPP国际标准组织开始研发5G。5G的主要应用场景为:eMBB(Enhanced Mobile Broadband,增强移动超宽带)、URLLC(Ultra Reliable Low Latency Communication,低时延高可靠通信)、mMTC(Massive Machine Type Communication,大规模机器类通信)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
NR也可以独立部署,5G网络环境中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定一个一个新的RRC状态,即RRC_INACTIVE状态。这种状态有别于RRC_IDLE和RRC_ACTIVE状态。
RRC_IDLE(空闲态):移动性为基于UE的小区选择重选,寻呼由CN发起,寻呼区域由CN配置。基站侧不存在UE AS上下文。不存在RRC连接。
RRC_CONNECTED(连接态):存在RRC连接,基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE(非激活态):移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE AS上下文存在某个基站上,寻呼由RAN(Radio Access Network,无线接入网)触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
在5G NR中,网络可以为终端配置DRX(Discontinuous Reception,非连续接收)功能,使终端非连续地监听PDCCH,以达到终端省电的目的。图2示出了一种终端的DRX周期示意图。如图2所示,在一个DRX周期内,当终端确定处于DRX周期中的唤醒时间段时,则该终端允许监听PDCCH;当该终端被确定处于DRX周期中的休眠时间段时,则该终端不监听PDCCH。
每个MAC实体有一个DRX配置,DRX的配置参数包含:
- DRX-onDurationTimer:DRX周期开始时的持续时间。
- DRX-SlotOffset:DRX周期开始之前的延迟。
- DRX-InactivityTimer:指示MAC实体进行新的UL或DL传输的PDCCH所在的PDCCH时机之后的持续时间。
- DRX-RetransmissionTimerDL:接收到下行HARQ(Hybrid Automatic Repeat Request,混合自动重复请求)重发许可之前的最大持续时间。
- DRX-RetransmissionTimerUL:接收到上行HARQ重发许可之前的最大持续时间。
- DRX-LongCycleStartOffset:长DRX,以及长DRX周期与短DRX周期开始之前的延迟。
- DRX-ShortCycle(optional):短DRX周期。
- DRX-ShortCycleTimer(optional):UE遵循短DRX周期的持续时间。
- DRX-HARQ-RTT-TimerDL:UE收到指示下行HARQ重传之前的下行授权的最小持续时间。
- DRX-HARQ-RTT-TimerUL:UE收到指示上行HARQ重传的上行授权之前的最小持续时间。
如果终端配置了DRX,则终端需要在DRX激活期监听PDCCH。DRX激活期包括如下几种情况:
(1)DRX-onDurationTimer,DRX-InactivityTimer,DRX-RetransmissionTimerDL,DRX-RetransmissionTimerUL以及ra-ContentionResolutionTimer,这5个定时器中的任何一个定时器正在运行。
(2)在PUCCH上发送了SR并处于pending等待状态。
(3)在基于竞争的随机接入过程中,终端在成功接收到随机接入响应后还没有接收到C-RNTI加扰的PDCCH指示的一次初始传输。
终端根据当前是处于长DRX周期还是短DRX周期,来决定启动DRX-onDurationTimer的时间,具体规定如下:
如果使用的是短DRX周期,并且当前子帧满足[(SFN×10)+subframe number]modulo(DRX-ShortCycle)=(DRX-StartOffset)modulo(DRX-ShortCycle);或者如果使用的是长DRX周期,并且当前子帧满足[(SFN×10)+subframe number]modulo(DRX-LongCycle)=DRX-StartOffset。其中,SFN是指系统帧号。
在当前子帧开始的DRX-SlotOffset个slot之后的时刻启动DRX-onDurationTimer。
终端启动或重启DRX-InactivityTimer的条件为:
如果终端接收到一个指示下行或者上行初始传输的PDCCH,则终端启动或者重启 DRX-InactivityTimer。
终端启动和停止DRX-RetransmissionTimerDL的条件为:
当终端接收到一个指示下行传输的PDCCH,或者当终端在配置的下行授权资源上接收到一个MAC PDU,则终端停止该HARQ进程对应的DRX-RetransmissionTimerDL。终端在完成针对这次下行传输的HARQ进程反馈的传输之后启动该HARQ进程对应的DRX-HARQ-RTT-TimerDL。
如果终端的某个HARQ对应的定时器DRX-HARQ-RTT-TimerDL超时,并且使用这个HARQ进程传输的下行数据解码不成功,则终端启动这个HARQ进程对应的DRX-RetransmissionTimerDL。
终端启动和停止DRX-RetransmissionTimerUL的条件为:
当终端接收到一个指示上行传输的PDCCH,或者当终端在配置的上行授权资源上发送一个MAC PDU,则终端停止该HARQ进程对应的DRX-RetransmissionTimerUL。终端在完成这次PUSCH的第一次重复传输(repetition)之后启动该HARQ进程对应的DRX-HARQ-RTT-TimerUL。
如果终端的某个HARQ对应的定时器DRX-HARQ-RTT-TimerUL超时,则终端启动这个HARQ进程对应的DRX-RetransmissionTimerUL。
基于目前的DRX机制,drx-HARQ-RTT-TimerUL/drx-HARQ-RTT-TimerDL和RetransmissionTimerUL/RetransmissionTimerDL都是基于每个UL/DL HARQ进程分别维护的。drx-HARQ-RTT-TimerUL和drx-HARQ-RTT-TimerDL分别为UE期待针对对应HARQ进程的重传调度的最小时间间隔。同时,对于配置了的DRX的UE,该UE在DRX Active Time监听PDCCH。因此,对于drx-HARQ-RTT-TimerUL和drx-HARQ-RTT-TimerDL有一种理解是:在某个HARQ进程i的drx-HARQ-RTT-TimerUL(如果HARQ进程i为上行HARQ进程)或drx-HARQ-RTT-TimerDL(如果HARQ进程i为下行HARQ进程)运行期间,如果由于别的原因导致UE当前处于DRX Active Time,(比如其他HARQ进程的RetransmissionTimerUL/RetransmissionTimerDL正在运行,或者drx-InactivityTimer正在运行,等等),由于UE的行为是需要监听PDCCH,因此网络仍然可以在此期间调度HARQ进程i的重传。也就是说,UE仍然可能在HARQ进程i对应的HARQ RTT timer运行期间接收到网络的调度该HARQ进程的PDCCH。基于目前协议描述,以上行为例,如果UE收到PDCCH指示一个上行传输,则UE停止该HARQ进程对应的RetransmissionTimerUL,并且在终端在完成这次PUSCH的第一次重复传输(repetition)之后的第一个符号启动该HARQ进程对应的drx-HARQ-RTT-TimerUL。如果UE是在该HARQ进程的drx-HARQ-RTT-TimerUL运行期间收到该PDCCH的,则在UE发送PUSCH之前,可能由于drx-HARQ-RTT-TimerUL超时而启动RetransmissionTimerUL,导致UE额外的耗电。
下文中以第一上行/下行HARQ进程来表示上述HARQ进程i。
本申请实施例基于DRX机制,针对如何在RRC连接状态下,通过确定终端的DRX定时器的状态,实现控制终端对下行物理控制信道PDCCH进行监听,提供可行的方案。且在本申请中,DRX与drx均为非连续接收(Discontinuous Reception)的缩写,其表示的内容一致。
图3示出了本申请一个实施例提供的定时器状态更改方法的流程图,该方法可以由终端执行,其中,上述该终端可以是图1所示的网络架构中的终端10。该方法可以包括如下步骤:
步骤301:在该终端的第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL运行期间,在该终端的传输满足第一条件的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。
在一种可能的实现方式中,该第一条件包括:该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,传输第一MAC PDU。其中,该第一上行HARQ进程是该终端的上行HARQ进程中的任意一个。
在一种可能的实现方式中,在该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,传输第一MAC PDU的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。其中,该第一MAC PDU是使用该第一上行HARQ进程传输的MAC PDU。
当终端使用第一上行HARQ进程传输第一MAC PDU时,由于终端通过第一上行HARQ进程传输第一MAC PDU之后,网络侧设备在一定时间内不会通过PDCCH下发相应的指示信息,因此终端在一定时间内不需要对PDCCH进行监听,此时终端可以更新该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL,避免由于第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL超时所导致对PDCCH的监听。
在一种可能的实现方式中,在该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,通过CG免授权在PUSCH进行该第一MAC PDU的N次重复传输,且未接收到物理层发送的先听后说LBT失败指示的情况下,调更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行 状态。
该终端可以在第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,通过CG免授权,通过至少一个绑定(bundle)的数据传输,以实现传输第一MAC PDU,且该终端未接收到物理层发送的先听后说LBT失败指示时,说明该终端成功向PUSCH发送了该信道,此时终端可以更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,使得PDCCH的监听延迟,避免不必要的功率消耗。
在一种可能的实现方式中,当使用该第一上行HARQ进程执行该第一MAC PDU对应的PUSCH传输的第一次重复传输时,停止该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL。
在一种可能的实现方式中,在使用该第一上行HARQ进程完成该第一MAC PDU对应的PUSCH传输的第一次重复传输之后的第一个时间符号,启动或重启该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL。
在一种可能的实现方式中,在该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,终端接收到PDCCH指示使用该第一上行HARQ进程传输该第一MAC PDU的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。
该终端还可以在第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,接收到网络侧设备通过PDCCH下发的第一指示信息进行N次数据传输以传输该第一MAC PDU,此时终端在第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,仍然通过其他的HARQ接收到了网络侧设备通过PDCCH下发的第一指示信息,并根据该第一指示信息进行N次数据传输以传输该第一MAC PDU的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,使得该第一HARQ延迟监听,避免不必要的功率消耗。
在一种可能的实现方式中,当该终端接收到该PDCCH时,停止该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL。
在一种可能的实现方式中,在使用该第一上行HARQ进程完成该第一MAC PDU对应的PUSCH传输的第一次重复传输之后的第一个时间符号,启动该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL。
在一种可能的实现方式中,当终端接收到该PDCCH指示使用该第一上行HARQ进程传输该第一MAC PDU时,停止该第一上行HARQ进程对应的第一RetransmissionTimerDL。
综上所述,本申请实施例所示方案中,当终端的第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL运行时,且终端的传输过程满足第一条件时,网络侧设备在上行传输发生的一段时间内可能不会向终端下发PDCCH,终端此时不需要对PDCCH进行监听,因此终端可以更改第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,比如通过停止或重启等方式来合理延长RTT的下次超时时间,减少了终端由于DRX-HARQ-RTT-Timer超时所导致的不必要的监听,减小了终端的功率消耗,节省了终端的电量。
图4示出了本申请一个实施例提供的定时器状态更改方法的流程图,该方法可以由终端和网络侧设备执行,其中,上述该终端可以是图1所示的网络架构中的终端10,网络侧设备可以是图1所示的网络架构中的基站20。该方法可以包括如下步骤:
步骤401:根据第一配置信息,确定该终端对应的DRX配置参数。
其中,该DRX配置参数用于配置该终端对应的各个DRX定时器。
在一种可能的实现方式中,该第一配置信息是网络侧设备通过下行信令下发至该终端的。
在另一种可能的实现方式中,该第一配置信息可以是预先存储在该终端中的。
即该终端可以先根据预先存储在该终端的第一配置信息,对该终端的DRX定时器进行配置。
在一种可能的实现方式中,该第一配置信息还用于指示该终端的HARQ进程数。当该终端的HARQ进程数大于等于2时,该终端可以根据该第一配置信息,配置出多个HARQ进程,以实现与网络侧设备的数据传输。
步骤402:在该终端的第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL运行期间,在与该终端的传输满足第一条件的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。
其中,该第一上行HARQ进程是该终端的上行HARQ进程中的任意一个。
在一种可能的实现方式中,当该第一上行HARQ进程满足第一条件时,终端可以更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,以便终端可以根据该第一上行HARQ进程执行的操作更新该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL,使得该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的计时功能更加准确,避免了终端在不必要的时刻由于第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL超时导致对PDCCH信道进行监听的情况的发生,减小了终端的功率消耗,节省了终端的电量,延长终端的续航时间。
在一种可能的实现方式中,在该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运 行期间,传输第一MAC PDU的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。其中,该第一MAC PDU是该第一HARQ对应的MAC PDU。
其中,该第一上行HARQ进程满足第一条件为,该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,传输第一MAC PDU。此时在终端使用第一上行HARQ进程传输第一MAC PDU的情况下,可以更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态,保证该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL与当前第一上行HARQ进程的传输状态对应,避免该终端在不必要的时刻执行监听。
在一种可能的实现方式中,在该终端在该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行期间,通过CG免授权在PUSCH进行该第一MAC PDU的N次重复传输,且未接收到物理层发送的先听后说LBT失败指示的情况下,更改该第一上行HARQ进程对应的DRX-HARQ-RTT-TimerUL的运行状态。

> stop the drx-HARQ-RTT-TimerDL for the corresponding HARQ process.2>start the drx-HARQ-RTT-TimerDL for the corresponding HARQ process in the first symbol after the end of the corresponding transmission carrying the DL HARQ feedback;
> stop the drx-RetransmissionTimerDL for the corresponding HARQ process.
2> if the PDCCH indicates a DL transmission:
> stop the drx-HARQ-RTT-TimerDL for the corresponding HARQ process.
> start the drx-HARQ-RTT-TimerDL for the corresponding HARQ process in the first symbol after the end of the corresponding transmission carrying the DL HARQ feedback;
NOTE 3:When HARQ feedback is postponed by PDSCH-to-HARQ_feedback timing indicating a non-numerical k1value,as specified in TS 38.213[6],the corresponding transmission opportunity to send the DL HARQ feedback is indicated in a later PDCCH requesting the HARQ-ACK feedback.
> stop the drx-RetransmissionTimerDL for the corresponding HARQ process.
> if the PDSCH-to-HARQ_feedback timing indicate a non-numerical k1value as specified in TS 38.213[6]:
> start the drx-RetransmissionTimerDL in the first symbol after the PDSCH transmission for the corresponding HARQ process.
即与下行HARQ对应的定时器状态更改方法,还可以包括以下步骤:
1.UE接收网络RRC的DRX配置。
2.如果UE在SPS上收到一个MAC PDU,此时UE的行为为:
停止该HARQ进程对应的drx-HARQ-RTT-TimerDL;
在完成针对该下行传输的HARQ反馈传输后的第一个(时间)符号启动该HARQ进程对应的drx-HARQ-RTT-TimerDL;
停止该HARQ进程对应的RetransmissionTimerDL;
3.如果UE接收到指示上行传输的PDCCH,则UE的行为为:
停止该HARQ进程对应的drx-HARQ-RTT-TimerDL;
在完成针对该下行传输的HARQ反馈传输后的第一个(时间)符号启动该HARQ进程对应的drx-HARQ-RTT-TimerDL;
停止该HARQ进程对应的RetransmissionTimerDL。
4.当HARQ反馈根据PDSCH-to-HARQ反馈时间指示延迟,该反馈时间指示一个非数值的k1值,如TS 38.213所规定的那样,发送DL HARQ反馈的相应传输时机在稍后请求HARQ-ack反馈的PDCCH中被指示;
停止该HARQ进程对应的RetransmissionTimerDL;
当PDSCH-to-HARQ反馈时间如TS 38.213所规定的那样,指示一个非数值型的k1值;
在相应的HARQ进程的PDSCH传输后的第一个符号中启动drx-RetransmissionTimerDL。
即上述方案记载的是,UE在收到指示下调度的PDCCH后,停止该下行HARQ进程对应的drx-HARQ-RTT-TimerDL,或者,UE在SPS上收到MAC PDU之后,停止该下行HARQ进程对应的drx-HARQ-RTT-TimerDL。
