  • the basic mechanism of DRX is to configure a DRX cycle for the UE in RRC CONNECTED state.
  • the DRX cycle consists of On Duration (wake-up period) and Opportunity for DRX (sleep period).
  • On Duration the UE monitors and receives PDCCH; during the "Opportunity for DRX" time During the DRX period, the UE does not receive PDCCH to reduce power consumption.
  • the DRX cycle defines a periodic repetition of wake-up periods followed by possible inactivity periods, as shown in Figure 1.
  • NR supports two types of DRX cycles: long DRX cycle and short DRX cycle, depending on the length of time the UE monitors a specific scheduling channel after waking up. If it is predicted that UE data arrives frequently or the service is sensitive to latency, the network side can configure the UE to use a short DRX cycle; if it is predicted that UE data is sparse and insensitive to latency, the network side can configure the UE to use only a long DRX cycle.

If the data arrival cycle is a non-integer, it will cause the data arrival cycle and the DRX cycle to not match. After a period of time, the data arrival time will fall into the sleep period. In this way, the UE will not be able to monitor the PDCCH, which will affect the timely scheduling of data and increase data transmission delays.

  • the duration of the wake-up period of a non-integer DRX cycle can be set to be longer than the duration of the wake-up period of the DRX cycle corresponding to other values of the maximum value of the starting offset. That is, the network side can configure a longer wake-up period (that is, a longer onDurationTimer) when the offset is configured to be floor(non-integer long DRX cycle)-1. In particular, the network side configures a longer wake-up period after the offset floor(non-integer long DRX cycle) corresponding to the expected arrival time of the periodic traffic, such as a value 1 millisecond larger than the usual configuration. Thereby, the problem that the terminal device may start the wake-up period in advance due to the aforementioned configuration, thereby missing the services that arrive later, is avoided.
  • the terminal device when a non-integer DRX cycle is configured and the actual cycle length of the previous DRX cycle is equal to the value obtained by rounding down the non-integer DRX cycle plus 1, the terminal device extends the wake-up period of the current DRX cycle.

Description

非连续接收周期的配置方法和装置 技术领域
本申请涉及通信领域。
背景技术
在3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)服务和网络中支持扩展现实(eXtended Reality,XR)业务,XR业务指的是计算机技术和可穿戴设备产生的所有现实和虚拟组合的环境和人机交互。其应用领域包括但不限于娱乐、医疗、教育等。XR业务可以包括虚拟现实(Virtual reality,VR)业务、增强现实(Augmented reality,AR)业务和混合现实(Mixed reality,MR)业务等代表形式及混合交叉的领域。
虚拟现实是发布的视觉和音频场景的渲染版本,当观察者或用户在应用程序定义的限制内移动时,渲染旨在尽可能自然地模拟现实世界的视觉和听觉感官刺激。增强现实是指向用户提供附加信息或人工生成的项目或覆盖在其当前环境上的内容。混合现实是AR的一种高级形式,其中一些虚拟元素被插入到物理场景中,目的是提供一种错觉,让人感觉这些元素是真实场景一部分。
PDU Set(PDU集)由一个或多个PDU(Protocol Data Unit,协议数据单元)组成,这些PDU携带了在应用层生成的一个信息单元的有效载荷,例如,用于XR和媒体服务的帧或视频切片。在一些实施方式中,应用层需要PDU Set中的所有PDU来使用相应的信息单元。在其他实施方式中,当某些PDU丢失时,应用层仍然可以恢复全部或部分信息单元。
应该注意,上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现,为了降低终端设备的功耗,3GPP从3G时代就开始使用非连续接收(DRX)技术。当终端设备被配置了DRX时,终端设备不需要连续地监听物理下 行控制信道(PDCCH),从而达到节能的目的。
为了使终端设备在使用XR业务时降低功耗,可以将DRX周期和数据到达周期匹配,并将唤醒期和数据到达时间大致对齐,这样,在数据到达时,UE可以监听基站发送的PDCCH,从中得到调度信息,对数据进行及时的调度。然而,目前的DRX周期定义为单位为毫秒的不同的整数值,如果数据到达周期为非整数,那么就会导致该数据到达周期和DRX的周期不匹配,在一段时间后,会发生数据到达时间落在休眠期的情况,这样UE将监听不到PDCCH,从而会影响对数据的及时调度,增加数据传输延迟。
针对上述问题至少之一或者其他类似问题,本申请实施例提供了一种非连续接收(DRX)周期的配置方法和装置。
根据本申请实施例的一方面,提供一种DRX周期的配置装置,应用于网络设备,所述装置包括:
发送单元,其向终端设备发送第一配置消息,所述第一配置消息配置了由一个或多个分数表示的非整数的DRX周期;所述第一配置信息包括第一信息单元,所述第一信息单元包括指示非整数的长DRX周期及其起始偏移量和/或指示非整数的短DRX周期的字段。
根据本申请实施例的另一方面,提供一种DRX周期的配置装置,应用于网络设备,所述装置包括:
发送单元,其向终端设备发送第二配置消息,所述第二配置消息配置了针对配置授权的禁用CG重传监听;所述第二配置消息包含第二信息单元,所述第二信息单元包括第六字段,所述第六字段指示了针对配置授权的禁用CG重传监听。
本申请实施例的有益效果之一在于:根据本申请实施例,通过在RRC和/或MAC层进行DRX相关的增强,来解决不同XR业务流量的到达周期以及多XR业务流量的情况下的DRX配置和操作问题,更好地支持针对XR业务以及媒体业务的UE节能。

目前,5G技术正在研究支持先进媒体服务的关键问题、解决方案和结论,例如高数据速率低延迟(HDRLL,High Data Rate Low Latency)服务、AR/VR/XR服务和触觉/多模态通信服务。目标包括:
1.支持多模式服务的增强功能,包括:
-研究是否以及如何启用应用程序在类似时间向用户提供相关的触觉和多模式数据(例如,与特定时间相关的音频、视频和触觉数据),重点关注增强策略控制的需求(例如QoS策略协调)。
2.增强网络暴露以支持5GS(5G系统)与应用程序之间的交互,包括:
-研究是否以及如何在多个UE之间或每个UE的多个QoS流之间进行应用同步和QoS(Quality of Service,服务质量)策略协调,以及如何在AF和5GS之间进行交互。
-研究5GS QoS信息(例如QoS能力)和网络条件对应用程序的暴露,以实现快速编解码器/速率自适应,有助于提供所需的QoE(例如帮助缓解5GS拥塞)。

-考虑到PDU Set的不同重要性,支持差异化的QoS处理。例如,合法丢弃属于不太重要的PDU Set的数据包,以减少资源浪费。
-是否以及如何支持上行链路-下行链路传输协调以满足UE到UPF(User Plane Function,用户面功能)的N6终结点之间的RTT(Round Trip Time,往返时间)延迟要求。
-潜在的策略增强以最大限度地减少抖动,重点是来自AF(Application Function,应用功能)的需求供应、PCC(policy and charging control,策略和计费控制)规则的扩展。
为了降低UE的功耗,3GPP从3G时代就开始使用DRX技术。DRX的全称是Discontinuous Reception(非连续接收),DRX在RRC IDLE(空闲态)和RRC CONNECTED(连接态)下的机制是不同的。空闲态下的DRX机制即寻呼机制,就是网络侧通过下发paging消息唤醒UE,在本申请实施例中,以连接态下的DRX(Connected DRX,C-DRX)为例进行说明。在以下的说明中,如无特别说明,DRX是指UE处于连接态时所使用的DRX,也就是C-DRX。
当UE被配置了DRX时,UE不需要连续地监听PDCCH(Physical Downlink Control Channel,物理下行控制信道),从而达到节能的目的。UE的MAC实体可以被RRC信令配置DRX功能,用于控制UE的关于MAC实体的某些RNTI(Radio Network Temporary Identifier,无线网临时标识)的PDCCH监听活动。
DRX的基本机制是为处于RRC CONNECTED态的UE配置一个DRX cycle(DRX周期)。DRX cycle由On Duration(唤醒期)和Opportunity for DRX(休眠期)组成。在“On Duration”时间内,UE监听并接收PDCCH;在“Opportunity for DRX”时间 内,UE不接收PDCCH以减少功耗。DRX周期定义了唤醒期跟随着可能的非活动时期的周期重复,如图1所示。
为了兼顾省电和时延,根据UE醒来以后监听特定调度信道的时间的长度,NR支持两种DRX周期:长DRX周期和短DRX周期。如果预测到UE数据到达比较频繁或者业务对时延比较敏感,网络侧可以配置UE使用短DRX周期;如果预测到UE数据比较稀疏且对时延不敏感,网络侧可以配置UE仅使用长DRX周期。为了便于UE进行长短DRX周期的切换,要求长DRX周期是短DRX周期的整数倍,这样可以保证两者的持续监听时间(onDuration)对齐。
发明人发现,现有的XR业务的帧速率有很多种,其中大多数帧速率对应了非整数的数据到达周期。如果以毫秒为单位,XR业务流量的到达周期(简称为XR流量周期或者数据发送周期,等等)可能会是非整数(有理数)。比如说帧速率为15,30,45,60,72,90和120帧每秒的XR业务分别对应了非整数(分别为66.66,33.33,22.22,16.66,13.88,11.11和8.33毫秒)的数据周期。
目前的DRX周期定义为单位为毫秒的不同的整数值。为了使UE在使用XR业务时降低功耗,可以将DRX周期和数据(例如XR业务流量)到达周期匹配,并将唤醒期和数据到达时间大致对齐,这样,在数据到达时,UE可以监听基站发送的PDCCH,从中得到调度信息,对数据进行及时的调度。如果数据到达周期为非整数,那么就会导致该数据到达周期和DRX的周期不匹配,在一段时间后,会发生数据到达时间落在休眠期的情况,这样UE将监听不到PDCCH,从而会影响对数据的及时调度,增加数据传输延迟。
图2以帧速率为60帧每秒(对应数据到达周期约为16.67毫秒)为例,如果将DRX周期设为16毫秒,经过几个DRX周期之后,会导致DRX唤醒期和数据到达时间(图2中66.67ms处)不对齐的问题。
在考虑XR业务流量的到达周期特点情况下,如何解决DRX周期和XR业务流量的到达周期的不匹配的问题需要进行进一步标准化和技术实现。
下面结合附图对本申请的各种实施方式进行说明。这些实施方式只是示例性的,不是对本申请的限制。在下面的说明中,“如果…”、“在…的情况下”、“当…时”等说法含义相同,可以互换。
第一方面的实施例
本申请实施例提供一种DRX周期的配置方法,从网络设备的一侧进行说明。图3是本申请实施例的DRX周期的配置方法的一示意图。如图3示,该方法包括:
310:网络设备向终端设备发送第一配置消息,所述第一配置消息配置了由一个或多个分数表示的非整数的DRX周期;所述第一配置信息包括第一信息单元,所述第一信息单元包括指示非整数的长DRX周期及其起始偏移量和/或指示非整数的短DRX周期的字段。
值得注意的是,以上附图1仅示意性地对本申请实施例进行了说明,但本申请不限于此。例如还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型,而不仅限于上述附图3的记载。
根据上述实施例,解决了DRX周期不支持非整数数据到达周期的问题,实现了UE节能。
在一些实施例中,第一配置消息为RRCReconfiguration消息,第一信息单元为DRX-Config IE。根据上述实施例,通过对RRC配置进行增强,使RRC能够配置DRX周期为有理数(也即分数),解决了DRX周期不支持非整数数据到达周期的问题。
在上述实施例中,以针对RRCReconfiguration消息中的DRX-Config IE进行增强,增加支持DRX周期为有理数的配置为例,但本申请不限于此。也可以对其他配置消息中的其他信息单元进行增强,或者在RRCReconfiguration消息或其他配置消息中增加新的IE来进行上述配置。
为了方便说明,下面以针对RRCReconfiguration消息中的DRX-Config IE进行增强为例。
在一些实施例中,对非整数的长DRX周期和起始偏移量进行统一定义。
在上述实施例中,第一信息单元包括第一字段,该第一字段包括与帧率对应的非整数(分数)的长DRX周期及其对应的起始偏移量的组合,例如可以称为drx-NonIntegerLongCycleStartOffset,本申请不限于此,该第一字段也可以有其他名字。
在上述实施例中,第一字段例如为CHOICE结构,该CHOICE结构中的每个元素为预定义的对应某帧率的非整数的长DRX周期和其对应的以毫秒为单位的起始偏移量的组合。第一字段为CHOICE结构,表明了配置时从事先定义好的对应某个帧率的非整数的长DRX周期和对应的以毫秒为单位的起始偏移量中进行选择。
在上述实施例中,非整数的长DRX周期可以由以毫秒为单位的分数表达,该分数由整数的分子和分母表达,例如200/3ms,此外,每个非整数的长DRX周期对应的起始偏移量的取值范围是0到对该非整数的长DRX周期向下取整的值,例如0~66。
下面是第一字段的一个示例:
在上面的示例中,第一字段drx-NonIntegerLongCycleStartOffset包含了以毫秒为单位的分数值drx-NonIntegerLongCycle(非整数的长DRX周期)和以毫秒为单位的drx-StartOffset(起始偏移量)。其中值“ms200/3”对应的是200/3毫秒,也就是帧率为15帧每秒(1000ms/15fps=200/3ms),其他分数值以此类推。此外,上述示例中,“ms200/3”只是一种用两个整数(分子和分母,通常为互质的整数)来表示一个分数的方法,本申请对此不做限制,还可以表示为“ms200by3”,“ms200over3”等等。上面的示例中定义的非整数的长DRX周期分别对应了15fps,30fps,45fps,60fps,72fps,90fps,120fps的帧率。
在上述实施例中,如果第一字段被配置,终端设备可以忽略drx-LongCycleStartOffset(也就是整数的长DRX周期和对应的起始偏移量)的配置。由此,避免了终端行为的模糊。
在上述实施例中,第一信息单元还可以包括第二字段,该第二字段包括与帧率对应的非整数的短DRX周期。
在上述实施例中,针对非整数的短DRX周期,可以在DRX-Config IE中定义新的第二字段,该第二字段为对应某个帧率的非整数(分数)的短DRX周期。该第二字段例如可以称为drx-NonIntegerShortCycle,本申请不限于此,该第二字段也可以有其他名字。
在上述实施例中,该第二字段可以是枚举类型,使用时从事先定义好的由分数表达的以毫秒为单位的短DRX周期中进行选择。
下面是第二字段的一个示例:
在上面的示例中,第二字段中的值“ms200/3”对应的是200/3毫秒,以此类推。
在上述实施例中,如果第二字段被配置,终端设备可以忽略drx-ShortCycle(也就是整数的短DRX周期)的配置。由此,避免了终端行为的模糊。
在上述实施例中,如果第二字段被配置,第一字段中的非整数的长DRX周期的值必须是第二字段的值的整数倍。比如第二字段被配置为ms100/3,第一字段中的非整数的长DRX周期可以配置为ms200/3。由此,可以保证两者的持续监听时间(onDuration)对齐。
在另一些实施例中,对非整数的长DRX周期和起始偏移量分别定义。
在上述实施例中,第一信息单元包括第三字段和第四字段,例如在DRX-Config IE中定义新的第三字段和第四字段。第三字段包括与帧率对应的非整数的长DRX周期,第四字段包括针对上述非整数的长DRX周期的起始偏移量。
在上述实施例中,第三字段定义了非整数(分数)的长DRX周期,比如叫做drx-NonIntegerLongCycle,由两个整数(第一整数和第二整数)来表示,比如叫做N1和N2,其中N1表示上述非整数的长DRX周期的分数表达形式N1/N2中的分子,N2表示上述非整数的长DRX周期的分数表达形式N1/N2中的分母。
在上述实施例中,N1和N2可以为整数型,取值范围分别为支持的非整数的长DRX周期的分数表达形式中的分子和分母的变化范围。这样,N1和N2可以在各自的范围内任意取值,扩展性强,并且可以支持更多的不同数据速率的业务。
下面是第三字段的一个示例,示出了N1和N2分别为整数型的情况:

在上述实施例中,N1和N2也可以是枚举型,取值范围分别包括支持的非整数的长DRX周期的分数表达形式中的分子和分母的固定值,还可以分别包括保留的备用位。这样信令开销要小一些,也保持了一定扩展性,可以支持更多的不同数据速率的业务。
下面是第三字段的另一个示例,示出了N1和N2分别为枚举型的情况:
在上述实施例中,以第三字段包括N1和N2两个整数为例,由于N1和N2是为了用分数表明XR视频业务的非整数周期,实际就是由1000毫秒除以帧率并进行约分所得。在一些实施方式中,也可以不进行约分,也就是直接使用N1=1000ms,N2=帧率,则这种情况下,不需要指示N1,只需要指示帧率即可。
也即,上述第三字段也可以仅包括一个整数,也即第二整数,例如N2,来表示非整数的长DRX周期。终端设备在收到该第三字段后,可以将1000毫秒与该第二整数的商,也即1000/N2作为分数表示的非整数的长DRX周期。
在上述实施例中,第四字段定义了针对非整数的长DRX周期的起始偏移量,比如叫做drx-StartOffsetForNonIntCycle。该第四字段可以为整数类型,取值范围可以是0到Nmax。Nmax为支持的最大非整数的长DRX周期向下取整的值,比如66毫秒。
在上述实施例中,当第三字段被配置时,第四字段必须被配置。由此,能够保证非整数的长DRX周期的配置的完整性。
在上述实施例中,当第三字段被配置时,终端设备可以忽略drx-LongCycleStartOffset(也即整数的长DRX周期及其对应的起始偏移量)的配置。由此,避免了终端行为的模糊。
在上述实施例中,第一信息单元还包括第五字段,该第五字段包括与帧率对应的非整数的短DRX周期。
在上述实施例中,针对非整数的短DRX周期,可以在DRX-Config IE中定义新的第五字段,第五字段定义了对应某个帧率的非整数(分数)的短DRX周期。该第五字段例如可以称为drx-NonIntegerShortCycle,由两个整数来表示,字段设计和第三字段一样,也可以由上述两种示例来表示。
例如,第五字段包括第三整数和第四整数,第三整数为非整数的短DRX周期的分数表达形式中的分子,第四整数为非整数的短DRX周期的分数表达形式中的分母。
在一个示例中,第三整数和第四整数分别为整数型,第三整数的取值范围为支持的非整数的短DRX周期的分数表达形式中的分子的变化范围;第四整数的取值范围为支持的非整数的短DRX周期的分数表达形式中的分母的变化范围。
在另一个示例中,第三整数和第四整数分别为枚举型;第三整数的取值范围包含支持的非整数的短DRX周期的分数表达形式中的分子的固定值,还可以包含保留的备用位;第四整数的取值范围包含支持的非整数的短DRX周期的分数表达形式中的分母的固定值,还可以包含保留的备用位。
在上述实施例中,以第五字段包括第三整数和第四整数为例,与第三字段类似,在不进行约分的情况下,也可以不指示第三整数而只指示第四整数,也即,第五字段仅包括第四整数,该第四整数表示非整数的短DRX周期,终端设备将1000毫秒与该第四整数的商作为分数表示的非整数的短DRX周期。
在上述实施例中,第三字段和第五字段都是以毫秒为单位的有理数,表明非整数的DRX周期定义为N1/N2毫秒。
在上述实施例中,如果第五字段被配置,则第三字段的值必须是第五字段的值的整数倍。
在上述实施例中,与第三字段类似,如果第五字段被配置,终端设备可以忽略drx-ShortCycle(也即整数的短DRX周期)的配置。由此,避免了终端行为的模糊。
以上对非整数的长DRX周期、起始偏移量、非整数的短DRX周期的实施方式进行了说明,在本申请实施例中,还可以进一步对DRX唤醒期的起始时间的计算公式进行增强。也即在判断何时开始非整数的DRX周期的唤醒期时,需要通过公式进行计算。
另外,为了解决SFN(系统帧号)翻转时,DRX周期和SFN边界对不齐的问题,可以增加一个计数器(第一计数器),比如叫做DRX_SFN_COUNTER,该计数器在每SFN翻转时增加1,也即在SFN变化为0时的时隙的第一个字符时间将该第一计数器加1。该计数器初始值为0,最大值为65535。此外,还可以定义一个用于确定起始偏移量的时间参考系统帧号(SFN),比如叫做drx-TimeReferenceSFN,取值为0或者512,用于确定DRX的唤醒期的开始时间。终端设备使用在收到带有该时间参考SFN的DRX配置之前离指示的参考SFN最近的SFN。
在一些实施例中,终端设备确定启动上述非整数的DRX周期的唤醒期的时间。例如,当DRX周期被配置时,终端设备的MAC实体确定启动非整数的DRX周期的唤醒期的时间。
在一个示例中,
如果为某个DRX组使用了短DRX周期,且非整数的短DRX周期被配置(例如前述第二字段或第五字段被配置),且当前的第一计数器(DRX_SFN_COUNTER)、系统帧号(SFN)以及子帧号满足如下公式:
floor([(第一计数器×10240)+(系统帧号×10)+子帧号]modulo(非整数的短DRX周期))=floor([(时间参考系统帧号×10)+起始偏移量)]modulo(非整数的短DRX周期)),
则终端设备为上述DRX组在上述子帧号对应的子帧开始之后的时隙偏移量(drx-SlotOffset)时长之后开启唤醒定时器(drx-onDurationTimer)。
在另一个示例中,
如果为某个DRX组使用了长DRX周期,且非整数的长DRX周期被配置(例如前述第一字段或第三字段被配置),且当前的第一计数器(DRX_SFN_COUNTER)、系统帧号(SFN)以及子帧号满足如下公式:
floor([(第一计数器×10240)+(系统帧号×10)+子帧号]modulo(非整数的长DRX周期))=floor([(时间参考系统帧号×10)+起始偏移量)]modulo(非整数的长DRX周期)),
则终端设备在没有为激活的下行带宽部分(BWP,BandWidth Part)配置带有通过节能无线网临时标识加扰的循环冗余校验的下行控制信息(DCP,DCI with CRC scrambled by PS_RNTI)监听的情况下,为上述DRX组在上述子帧号对应的子帧开 始之后的时隙偏移量(drx-SlotOffset)时长之后开启唤醒定时器。
上述公式中modulo为取模(求余)计算,由于是对有理数(即非整数的DRX周期,由N1/N2表示)进行取模,为了在计算中不产生舍入误差,公式中的A modulo B(B=N1/N2)可以使用A-floor(A*N2/N1)*N1/N2来替代,且需要按照该替代公式中的操作符顺序来进行计算,从而不产生舍入误差。具体顺序指在计算时按照公式中从左到右的顺序进行操作运算。
下面是根据上述实施例对TS 38.321的DRX过程进行增强的一个示例:
在上述实施例中,DRX组(group)是指RRC配置的具有相同DRX激活时间(Active Time)的服务小区组。为了使不同DRX组的DRX周期对齐,可以将下面参数设为各DRX组公用:非整数的长DRX周期,起始偏移量,非整数的短DRX周期,以及 drx-TimeReferenceSFN。也即,在本申请实施例中,各DRX组可以公用以下参数:非整数的长DRX周期,所述非整数的长DRX周期对应的起始偏移量,非整数的短DRX周期,以及时间参考帧号。关于上述各参数的含义,已经在前面做了说明,其内容被合并于此,此处不再赘述。
在一些实施例中,考虑到上述公式中使用了第一计数器(DRX_SFN_COUNTER),该第一计数器需要在网络侧和终端侧同步,也就是保持同样的数值。终端设备可以在收到关于非整数的DRX周期的RRC配置(比如非整数的长DRX周期的RRC配置,也即上述第一配置消息)时,将该计数器初始化为0,并且在SFN变化为0时的时隙的第一个字符时间将该第一计数器加1。由于该第一计数器在每SFN翻转(wrap around)时增加1,如果在SFN刚刚翻转时(例如SFN=0或者是很小的值),终端设备收到关于非整数的DRX周期的RRC配置,由于有网络时延,终端设备不能判断网络侧发出该配置时SFN是否已经翻转,所以无法正确初始化DRX_SFN_COUNTER,也即无法和网络同步DRX_SFN_COUNTER。
在上述实施例中,终端设备可以根据上述RRC配置(例如上述非整数的DRX周期的RRC配置,也即上述第一配置消息)所携带的时间参考SFN(drx-TimeReferenceSFN)来进行上述第一计数器(DRX_SFN_COUNTER)的初始化。
例如,当终端设备收到网络侧发送的关于非整数的DRX周期的RRC配置时,如果时间参考SFN取值为0,那么说明网络侧发送该配置时SFN为整个SFN周期的前半部分(也即SFN 0-511),终端设备收到该配置时肯定不会发生SFN翻转,所以终端设备可以将DRX_SFN_COUNTER设为0。
再例如,当网络侧发送关于非整数的DRX周期的RRC配置时,如果时间参考SFN取值为512,那么说明当前SFN为整个SFN周期的后半部分(也即SFN 512-1023),如果终端设备收到该配置时SFN仍然为SFN周期的后半部分,那么说明没有发生SFN翻转,所以终端设备可以将DRX_SFN_COUNTER设为0;如果终端设备收到该配置时SFN处于SFN周期的前半部分,那么说明发生了SFN翻转,所以终端设备可以将DRX_SFN_COUNTER设为1。
由此,终端设备根据接收到的非整数的DRX周期的RRC配置所携带的时间参考SFN来进行上述DRX_SFN_COUNTER的初始化,可以保证网络侧和UE侧的 DRX_SFN_COUNTER同步。
在上述实施例中,非整数的DRX周期可以是非整数的长DRX周期,也可以是非整数的短DRX周期。
下面是根据上述实施例对TS 38.321的DRX过程进行增强的另一个示例,用于实现DRX_SFN_COUNTER的正确初始化:
在上述实施例中,在网络侧和终端侧实现了上述DRX_SFN_COUNTER的同步后,在上述非整数的DRX周期的相关公式中,可以省略时间参考SFN。
例如,当DRX周期被配置时,终端设备的MAC实体通过如下方法来确定启动非整数的DRX周期的唤醒期的时间:
如果为某个DRX组使用了短DRX周期,且非整数的短DRX周期被配置(例如前述第二字段或第五字段被配置),且当前的DRX_SFN_COUNTER、SFN、子帧号满足如下公式:
floor([(DRX_SFN_COUNTER×10240)+(SFN×10)+subframe number]modulo(非整数的短DRX周期))=floor((起始偏移量)modulo(非整数的短DRX周期)),
则终端设备为上述DRX组在上述subframe number对应的子帧开始之后的drx-SlotOffset(时隙偏移量)时长之后开启唤醒定时器(drx-onDurationTimer)。
如果为某个DRX组使用了长DRX周期,且非整数的长DRX周期被配置(例如前述第一字段或第三字段被配置),且当前的DRX_SFN_COUNTER、SFN、子帧号 满足如下公式:
floor([(DRX_SFN_COUNTER×10240)+(SFN×10)+subframe number]modulo(非整数的长DRX周期))=起始偏移量,
则终端设备在没有为激活的下行带宽部分(BWP,BandWidth Part)配置DCP(DCI with CRC scrambled by PS_RNTI)监听的情况下,为上述DRX组在上述subframe number对应的子帧开始之后的drx-SlotOffset时长之后开启唤醒定时器。
值得注意的是,上述公式中对分数进行modulo计算可以参考前面方法,以避免舍入误差。
根据上述实施例,进一步解决了DRX周期不支持非整数数据达到周期的问题。
在本申请实施例中,发明人进一步发现,对于非整数的DRX周期,由于在DRX唤醒期的起始时间的计算公式中使用了取整操作,从而导致DRX周期平均来讲是个有理数,但是单个DRX周期实际为整数,且每个DRX周期不一定完全相同,可能会有1毫秒的差别。
图4是DRX配置的一个示例的示意图。在图4的示例中,以XR业务帧率60fps(对应周期50/3ms)为例,将DRX周期(可以是长DRX周期,也可以是短DRX周期)配置为50/3毫秒,参考前面的配置方法。当起始偏移量配置为16ms的时候,可能会出现某个DRX周期没有唤醒期的问题,如图4中第三个周期。这样终端设备会监听不到下行控制信息,从而不能收发数据,导致传输时延。
针对上述问题,本申请实施例进一步提供了解决方案。
在一些实施例中,将起始偏移量的最大值配置为floor(非整数的长DRX周期)-1。
仍以第一信息单元包括第一字段,该第一字段为CHOICE结构,且包括与帧率对应的非整数的长DRX周期和起始偏移量为例,与前面实施例不同的是,该起始偏移量的最大值不再是对非整数的长DRX周期向下取整后得到的值,而是对非整数的长DRX周期向下取整后得到的值-1,如下:

根据上述实施例的方法,解决了DRX周期没有唤醒期的问题。
在上述实施例中,非整数的DRX周期的唤醒期的时长可以设置为比起始偏移量的最大值为其他值时对应的DRX周期的唤醒期的时长更长。也即,网络侧可以在配置偏移量为floor(非整数的长DRX周期)-1时,配置一个较长的唤醒期(也即较长的onDurationTimer)。尤其是网络侧在周期流量期望的到达时间对应的偏移量floor(非整数的长DRX周期)之后时,配置一个较长的唤醒期,比如比平常的配置大1毫秒的值。由此,避免了由于前述配置导致终端设备可能提前开启唤醒期从而错过较晚到达的业务的问题。
在上述实施例中,当配置了非整数的DRX周期且前一个DRX周期的实际周期长度等于对该非整数的DRX周期进行向下取整得到的值加1时,终端设备将当前的DRX周期的唤醒期延长。也即,如果起始偏移量被配置为floor(非整数的长DRX周期)-1,且前一个DRX周期长度等于floor(非整数的长DRX周期)+1时,终端设备自行将当前DRX周期的唤醒期延长,比如增加1毫秒。floor(非整数的长DRX周期)+1也等于ceil(非整数的长DRX周期)。Ceil(x)指对x向上取整。判断前一个DRX周期的实际长度可以由当前DRX周期的唤醒期的起始时间减去前一个DRX周期的唤醒期的起始时间得到。由此,避免了由于前述配置导致终端设备可能提前开启唤醒期从而错过较晚到达的业务的问题。
在另一些实施例中,起始偏移量的最大值仍然配置为floor(非整数的长DRX周期),而对UE侧进行增强。
例如,如果从上一个唤醒期定时器开始的时间过了一个DRX周期的长度之后唤醒期定时器没有运行过,则终端设备启动唤醒定时器。也即,当起始偏移量被配置为floor(非整数的长DRX周期)时,如果从上一个唤醒期定时器开始的时间过了一个DRX周期之后,唤醒期定时器没有运行过,则终端设备自主启动唤醒期定时器,也即开启唤醒期。此处的DRX周期可以是floor(非整数的长DRX周期)+1毫秒。由此,也解决了DRX周期没有唤醒期的问题。
前面以非整数的长DRX周期为例,本申请不限于此,非整数的短DRX周期以 此类推。
在本申请实施例中,发明人进一步发现,如果短DRX周期被配置且为非整数,且长DRX周期也为非整数(仍然为短DRX周期的整数倍),在某些配置的情况下会出现长短DRX周期的唤醒期没有对齐的情况。例如,长DRX周期配置为50/3ms,短DRX周期配置为25/3ms,起始偏移量配置为15ms,在某些时刻可能会出现图5所示的情况,也即,在31ms和48ms左右的时刻,短DRX周期的唤醒期和长DRX周期的唤醒期不在同时启动,由于该情况不符合传统协议标准,这样会造成一些终端设备的未知操作,增加设备开发的复杂度。
针对上述问题,本申请实施例进一步提供了解决方案。
在一些实施例中,当非整数的长DRX周期被配置时,短DRX周期不被配置。也即,针对上述问题,不定义非整数的短DRX周期。也就是支持非整数数据周期XR业务时,只能配置长DRX周期为非整数,配置了非整数的长DRX周期时,不配置短DRX周期。这种方法实现简单,减少设计复杂度。
在另一些实施例中,当非整数的短DRX周期被配置时,长DRX周期为整数。也即,针对上述问题,当配置了非整数的短DRX周期时,长DRX周期必须是整数,也即必须使用(现有的)drx-LongCycleStartOffset。这种方法保留了短DRX周期,提高了UE节能的灵活性,能够更好地支持数据突发。
在本申请实施例中,为了支持更好的UE节能,对配置授权(configured grant,CG)的上行调度传输,可以不启动上行HARQ(hybrid automatic repeat request)RTT(round-trip time)定时器(drx-HARQ-RTT-TimerUL),从而不启动重传,这对短周期的、时延敏感的XR业务尤其重要。
在一些实施例中,网络设备还可以向终端设备发送第二配置信息,该第二配置信息配置了针对配置授权的禁用CG重传监听。其中,该第二配置信息可以包括第二信息单元,该第二信息单元包括第六字段,该第六字段指示了针对配置授权的禁用CG重传监听。
在上述实施例中,第二配置消息例如可以是RRCReconfiguration消息,第二信息单元例如可以是ConfiguredGrantConfig IE,第六字段例如可以称为disableCG-RetransmissionMonitoring,本申请不限于此。根据本申请实施例,可以对每个配置授权增加一个配置,用于禁用CG重传监听,也就是对上行配置授权传输禁 止启动drx-HARQ-RTT-TimerUL定时器。由此,解决了CG不支持免上行重传的问题,增强了含有时延敏感业务,比如XR业务的UE节能。
在上述实施例中,如果配置授权是一个包含多(multi-)PUSCH(Physical Uplink Shared CHannel)的配置授权,也就是CG配置中在一个周期内包含了多个连续的配置上行授权(configured uplink grant),那么第六字段的配置适用于该配置授权中的所有配置上行授权,也就是所有的PUSCH传输时机(occasion)。在一些实施例中,当第六字段被配置时,对CG中的所有配置上行授权都禁止启动drx-HARQ-RTT-TimerUL定时器。由此,解决了多PUSCH的CG不支持免上行重传的问题,增强了含有时延敏感业务,比如XR业务的UE节能。
在一些实施例中,如果终端设备的服务小区没有被配置上行HARQ模式(uplinkHARQ-Mode),且如果没有为配置的上行授权所属的多PUSCH CG配置所述第六字段,则:
如果配置了drx-LastTransmissionUL,则在对应的PUSCH传输的(bundle内的)最后传输之后的第一个符号(symbol)为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器;
反之,则在对应的PUSCH传输的(bundle内的)第一个传输之后的第一个符号为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器。
下面是根据上述实施例的方法对TS 38.321的DRX过程进行增强的一个示例:

上述实施例的方法可以在DRX周期为非整数时使用,例如可以与前面实施例的通过第一配置信息配置非整数的DRX周期的方法结合使用,也可以在DRX周期为整数时使用,例如不与前面实施例的通过第一配置信息配置非整数的DRX周期的方法绑定而单独使用,本申请不限于此。
以上各个实施例仅对本申请实施例进行了示例性说明,但本申请不限于此,还可以在以上各个实施例的基础上进行适当的变型。例如,可以单独使用上述各个实施例,也可以将以上各个实施例中的一种或多种结合起来。
本申请实施例还提供一种DRX周期的确定方法,从终端设备的一侧进行说明。需要说明的是,该方法是与前述实施例的DRX周期的配置方法对应的UE侧的处理,其中与前述实施例相同的内容不再重复说明。
图6是本申请实施例的DRX周期的确定方法的一示意图,如图6所示,该方法包括:
610:终端设备接收网络设备发送的第一配置信息,该第一配置消息配置了由一个或多个分数表示的非整数的DRX周期;该第一配置信息包括第一信息单元,该第一信息单元包括指示非整数的长DRX周期及其起始偏移量和/或指示非整数的短DRX周期的字段。
在一些实施例中,如前所述,如果第一字段被配置,则终端设备忽略整数的长DRX周期及其对应的起始偏移量的配置。
在一些实施例中,如前所述,在第三字段仅包括第二整数的情况下,终端设备可以将1000毫秒与所述第二整数的商作为分数表示的非整数的长DRX周期。
在一些实施例中,如前所述,如果第三字段被配置,则终端设备忽略整数的长DRX周期及其对应的起始偏移量的配置。
在一些实施例中,如图6所示,该方法还可以包括:
620:终端设备确定启动所述非整数的DRX周期的唤醒期的时间。关于确定该非整数的DRX周期的唤醒期的时间的方法,已经在前面做了说明,此处不再赘述。
在上述实施例中,如前所述,如果起始偏移量的最大值为对非整数的DRX周期进行向下取整得到的值减1,则如果从上一个唤醒期定时器开始的时间过了一个DRX周期的长度之后唤醒期定时器没有运行过,终端设备可以启动唤醒定时器。
根据本申请实施例的方法,解决了DRX周期不支持非整数数据达到周期的问题,并支持多个PUSCH的配置授权的免上行重传传输,从而实现UE节能。

根据上述实施例,通过对每个配置授权增加一个配置,用于禁用CG重传监听,也就是对上行配置授权传输禁止启动drx-HARQ-RTT-TimerUL定时器,解决了在CG包括多PUSCH的CG的情况下不支持免上行重传的问题,增强了含有时延敏感业务,比如XR业务的UE节能。
在一些实施例中,第二配置信息为RRCReconfiguration消息;第二信息单元为ConfiguredGrantConfig IE。本申请不限于此。
在一些实施例中,当第六字段被配置时,对上述配置授权中的所有配置上行授权都禁止启动drx-HARQ-RTT-TimerUL定时器。
在上述实施例中,配置授权是一个包含多(multi-)PUSCH(Physical Uplink Shared CHannel)的配置授权,也就是CG配置中在一个周期内包含了多个连续的配置上行授权(configured uplink grant),第六字段的配置适用于该配置授权中的所有配置上行授权,也就是所有的PUSCH传输时机(occasion)。
在一些实施例中,如果终端设备服务小区没有被配置上行HARQ模式,且如果没有为配置的上行授权所属的多PUSCH CG配置所述第六字段,则:
如果配置了drx-LastTransmissionUL,则在对应的PUSCH传输的最后传输之后的第一个符号为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器;
反之,则在对应的PUSCH传输的第一个传输之后的第一个符号为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器。
本申请实施例还提供一种DRX配置的实施方法,从终端设备的一侧进行说明。需要说明的是,该方法是与前述实施例的DRX的配置方法对应的UE侧的处理,其中与前述实施例相同的内容不再重复说明。
图8是本申请实施例的DRX配置的实施方法的一示意图,如图8所示,该方法包括:
810:终端设备接收网络设备发送的第二配置消息,所述第二配置消息配置了针对配置授权的禁用CG重传监听;所述第二配置消息包含第二信息单元,所述第二信息单元包括第六字段,所述第六字段指示了针对配置授权的禁用CG重传监听。

反之,则终端设备在对应的PUSCH传输的第一个传输之后的第一个符号为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器。
以上各个实施例仅对本申请实施例进行了示例性说明,但本申请不限于此,还可以在以上各个实施例的基础上进行适当的变型。例如,可以单独使用上述各个实施例,也可以将以上各个实施例中的一种或多种结合起来。
根据本申请实施例的方法,解决了在CG包括多PUSCH的CG的情况下不支持免上行重传的问题,增强了含有时延敏感业务,比如XR业务的UE节能。

在一些实施例中,终端设备还可以对上述第一计数器进行初始化,例如,在收到第一配置消息时将第一计数器初始化为0;在SFN变化为0时的时隙的第一个字符时间将第一计数器加1。
在一些实施例中,终端设备可以根据接收到的第一配置消息所包含的时间参考SFN来初始化上述第一计数器。
例如,如果该时间参考SFN为0,则所述终端设备在收到第一配置消息时将第一计数器初始化为0。
再例如,如果该时间参考SFN为512,则终端设备在收到第一配置消息时的SFN为SFN周期的后半部分的情况下,将第一计数器初始化为0,在收到第一配置消息时的SFN为SFN周期的前半部分的情况下,将第一计数器初始化为1。
根据上述方法,能够实现网络侧和终端侧对第一计数器的同步。
在上述实施例中,由于网络侧和终端侧已经实现了对第一计数器的同步,则上述公式中的时间参考SFN可以省略。
例如,在终端设备确定启动非整数的DRX周期的唤醒期的时间时,如果为某个DRX组使用了短DRX周期,且非整数的短DRX周期被配置,且当前的第一计数器、SFN、子帧号满足如下公式:
floor([(第一计数器×10240)+(SFN×10)+子帧号]modulo(非整数的短DRX周期))=floor((起始偏移量)modulo(非整数的短DRX周期)),
则终端设备为上述DRX组在上述子帧号对应的子帧开始之后的时隙偏移量时长之后开启唤醒定时器。
再例如,在终端设备确定启动非整数的DRX周期的唤醒期的时间时,如果为某个DRX组使用了长DRX周期,且非整数的长DRX周期被配置,且当前的第一计数器、SFN、子帧号满足如下公式:
floor([(第一计数器×10240)+(SFN×10)+子帧号]modulo(非整数的长DRX周期))=起始偏移量,
则终端设备在没有为激活的下行带宽部分配置DCP监听的情况下,为上述DRX组在上述子帧号对应的子帧开始之后的时隙偏移量时长之后开启唤醒定时器。
在一些实施例中,上述起始偏移量的最大值被配置为对非整数的DRX周期进行向下取整得到的值减1。
在上述实施例中,非整数的DRX周期的唤醒期的时长可以比起始偏移量的最大值为其他值时对应的DRX周期的唤醒期的时长大。
在上述实施例中,当配置了非整数的DRX周期,且前一个DRX周期的实际周期长度等于对该非整数的DRX周期进行向下取整得到的值加1时,终端设备可以将当前的DRX周期的唤醒期延长。
在另外一些实施例中,上述起始偏移量的最大值被配置为对非整数的DRX周期进行向下取整得到的值。
在上述实施例中,如果从上一个唤醒期定时器开始的时间过了一个DRX周期的长度之后唤醒期定时器没有运行过,则终端设备启动唤醒定时器。
在前述各实施例中,非整数的DRX周期可以为非整数的长DRX周期,和/或,非整数的短DRX周期。
在一些实施例中,当非整数的长DRX周期被配置时,短DRX周期不被配置;或者,当非整数的短DRX周期被配置时,长DRX周期为整数。
在一些实施例中,如图9所示,该装置900还包括:

在上述实施例中,第二配置信息可以为RRCReconfiguration消息;第二信息单元可以为ConfiguredGrantConfig IE。
在上述实施例中,当第六字段被配置时,对配置授权中的所有配置上行授权都禁 止启动drx-HARQ-RTT-TimerUL定时器。
在上述实施例中,如果终端设备的服务小区没有被配置上行HARQ模式,且如果没有为配置的上行授权所属的多PUSCH CG配置所述第六字段,则:
如果配置了drx-LastTransmissionUL,则终端设备在对应的PUSCH传输的最后传输之后的第一个符号为对应的HARQ进程启动drx-HARQ-RT-TimerUL定时器;
