Description

一种非连续接收的通信方法及装置
本申请要求于2021年05月10日提交中国专利局、申请号为202110507807.4、申请名称为“一种非连续接收的通信方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种非连续接收的通信方法及装置。
背景技术
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的发布(Release)15标准中,接入网设备可以为用户设备(user equipment,UE)配置非连续接收(discontinuous reception,DRX)功能,使得UE在一段时间内没有调度传输可以进入DRX操作。在DRX操作下,UE周期性醒来监听物理下行控制信道(physical downlink control channel,PDCCH),从而可以达到节省UE功耗目的。接入网设备可以同时为UE配置长DRX周期和短DRX周期,其中长DRX周期和短DRX周期均为整数毫秒。
在无线通信网络中,扩展现实(extended reality,XR)技术具有多视角、交互性强等优点,能够为用户提供了一种全新的视觉体验,具有极大的应用价值和商业潜力。XR包含虚拟现实(virtual reality,VR)、增强现实(augmented reality,AR)、云游戏(cloud game,CG)。3GPP国际标准化组织在评估XR实时视频传输的业务模型和服务质量(quality of service,QoS)需求,XR业务的结论:AR/VR:60帧每秒(frame per second,fps),每秒60帧视频图像,即每16.66毫秒(millisecond,ms)出现一个视频帧,速率为20Mbps,45Mbps等;120fps,每秒120帧视频图像,即每8.33ms出现一个视频帧。一个完整的视频帧的空口传输时延预算是10ms。CG:每秒60帧视频图像或每秒120帧视频图像,速率为8Mbps,30Mbps等。一个完整的视频帧的空口传输时延预算是15ms。
虽然XR下行业务是周期性的,但其周期是非整数毫秒,导致不支持非整数毫秒周期的DRX无法匹配XR下行业务传输。因此如何可以使DRX的活动时间更灵活,从而支持XR下行业务,节省UE的功耗,成为亟待解决的问题。

可以理解,随着网络的演进,上述网元的名称可能发生变化,网元的功能也可能发生合并、分离、甚至改变,但这些变化并不意味着脱离了本申请方案的适用范围。
在3GPP国际标准化组织Release15标准中,接入网设备可以为UE配置DRX功能,使得UE在一段时间内没有调度传输可以进入DRX操作。如果没有DRX机制,UE就会一直监听(也称为监测)下行PDCCH,查看是否有来自服务小区的信息。然而在很多时候,UE并不是一直在和网络进行有效信息的交互,也不是一直在执行上传或下载业务,甚至在通话时也不会一直有语音数据的传输,因此UE一直监听下行PDCCH是一种浪费功耗的行为。引入DRX机制后,进入DRX操作的UE可以周期性的在某些时候进入睡眠状态,不去监听PDCCH,而在需要监听的时候从睡眠状态中唤醒,从而是UE达到节省功耗的目的。如图2示出了一种DRX周期示意图。在图2中,一个DRX周期包括持续时间和睡眠时间,其中UE在持续时间(On Duration)从睡眠状态中唤醒,监听下行PDCCH,UE在睡眠时间(Opportunity for DRX)进入睡眠状态,不再去监听PDCCH。从图2中可以看到,用于DRX睡眠时间越长,UE的功耗就越低。目前在3GPP标准中只支持周期为整数值,比如整数毫秒,的DRX。
在无线通信网络中,XR技术具有多视角、交互性抢等优点,能够为用户提供一种全新的体验,具有极大的应用价值和商业潜力。XR包含VR、AR和CG等技术,能够广泛应用于娱乐、游戏、医疗、广告、工业、在线教育、以及工程等诸多领域。VR技术主要是指对视觉和音频场景的渲染以尽可能地模拟现实世界中的视觉和音频对用户的感官刺激,VR技术通常要求用户佩戴XR终端(例如头戴式设备)进而向用户模拟视觉和/或听觉。VR技术还可以对用户进行动作跟踪,从而及时更新模拟的视觉和/或听觉内容。AR技术主要是指在用户感知的现实环境中提供视觉和/或听觉的附加信息或人工生成内容,其中,用户对现实环境的获取可以是直接的(例如不进行感测、处理和渲染),也可以是间接的(例如通过传感器等方式进行传递),并进行进一步的增强处理。CG技术主要是指将运算搬到云端处理,用户设备可以只负责传输和接收信息,使得大型游戏不再受场景限制。3GPP国际标准化组织在评估XR实时视频传输的业务模型和服务质量(quality of service,QoS)需求,下行业务的结论:AR/VR:60fps,每秒60帧视频图像,即每16.66ms出现一个视频帧,速率为20Mbps,45Mbps等。120fps,每秒120帧视频图像,即每8.33ms出现一个视频帧。一个完整的视频帧的空口传输 时延预算是10ms。CG:每秒60帧视频图像或每秒120帧视频图像,速率为8Mbps,30Mbps等。一个完整的视频帧的空口传输时延预算是15ms。
虽然XR下行业务是周期性的,但其周期是非整数值,所以不支持非整数周期的DRX无法匹配XR下行业务传输。如图3所示,图3示出了一种XR数据与DRX周期不匹配示意图。其中,XR数据周期以每秒60帧为例,即16.66ms,由于XR数据一般都在最近接发送时刻的子帧上发送,如第一帧数据在子帧(subframe,SF)0上发送,第二帧数据在SF17上发送,第三帧数据在SF34上发送,第四帧数据在SF50上发送,第五帧数据在SF67上发送,第六帧数据在SF84上发送,第七帧数据在SF100上发送。其中,配置的DRX周期以17ms为例,从图中可以看到,从第四帧数据开始,数据的发送时隙与DRX的On Duration时间不再匹配,并且不匹配的程度会累积,例如第四帧、第五帧、第六帧的XR数据与对应DRX的On Duration时间差1个子帧(1ms),而到第七帧XR数据与对应的DRX的On Duration时间差扩大为2个子帧(2ms),这就会导致XR业务的传输时延需求得不到满足,影响业务传输性能。
因此如何可以使得DRX的活动时间可以更灵活,从而可以使DRX支持XR场景,UE可以节省功耗,成为亟待解决的问题。
本申请提供了一种DRX的通信方法及装置,可以使得DRX的活动时间可以更灵活,从而可以使DRX支持XR场景,UE可以节省功耗。
请参见图4,图4示出了根据本申请实施例的通信方法400示意性流程图,在图4所示的通信方法中涉及接入网设备和用户设备(UE)。该通信方法400包括但不限于如下步骤:
S401接入网设备向UE发送SPS配置参数信息。
接入网设备向UE发送SPS配置参数信息,该SPS配置参数信息指示第一SPS的时域资源或第二SPS的时域资源中的一项或多项。由于XR数据的周期为非整数周期,所以可以配置多套整数周期的SPS,来传输非整数周期的XR的数据。本文中的第一SPS或第二SPS只是用于区分SPS,不代表只有一个或两个SPS,可以有多于两个SPS的配置,这里不对SPS的数量作限定。例如XR的数据以每秒60帧为例,即16.66ms,可以配置三套周期为50ms的SPS来传输周期为16.66ms的XR数据。该三套周期分别为第一SPS、第二SPS、第三SPS。接入网设备向UE发送SPS配置参数信息,该SPS配置参数信息指示第一SPS的时域资源或第二SPS的时域资源或第三SPS的时域资源中的一项或多项。SPS的配置参数信息可以包括如下参数的中一项或多项:SPS周期,SPS索引号,SPS时域资源位置等。

S402基于SPS配置参数信息确定DRX活动时间
UE在DRX活动时间可以监测服务小区的物理下行控制信道,该DRX活动时间与UE接收的SPS配置参数信息有关。物理下行控制信道(PDCCH)是无线通信网络中上下行业务调度的“中枢神经”,用于上下行调度、功控等控制信令的传输。PDCCH信道传输的信息主要包括:下行调度信息,上行调度信息,时隙格式指示,功控命令等信息中的一项或多项。XR数据的调度信息可以在PDCCH信道中传输。

可选地,该DRX活动时间可以通过在SPS资源上收到的MAC层信令确定。示例性地,DRX活动时间可以包括该第三计时器的运行时间,该第三计时器为UE收到MAC层信令后启动的第三计时器。该第三计时器包括DRX on-duration计时器或DRX Inactivity计时器中的至少一项。
可选地,基站给UE配置了SPS资源,但不发送下行数据,或者发送下行数据但不是所述UE的数据,比如其他UE的标识进行进行CRC加扰的下行数据,使得UE不能在SPS资源上成功接收下行数据,最后触发UE启动DRX-HARQ-RetransmisionTimerDL定时器,在DRX-HARQ-RetransmisionTimerDL运行期间处于DRX活动时间。
可选地,S403接入网设备向UE发送DRX配置参数信息。可以理解的是,S403的顺序可以在S401或S402之前,在此不予限定。
接入网设备向UE发送DRX配置参数信息,该DRX配置参数信息可以包括如下参数中的一项或多项:
·不连续接收的长周期(DRX-LongCycle),例如该长周期可以是50ms、60ms、70ms等整数周期。
·不连续接收的短周期(DRX-ShortCycle),例如该短周期可以是1ms、2ms、3ms等整数周期。
·不连续接收的持续时间定时器(DRX-On-DurationTimer),例如该持续时间定时器的 持续时间可以为10ms等整数时长,本文不对该时长做限定,UE在持续时间可以监听PDCCH。
·不连续接收的非活动定时器(DRX-InactivityTimer),例如该非活动定时器的时长可以为5ms等整数,本文不对该时长做限定,UE在收到PDCCH调度新的上行或下行传输业务的PDCCH时刻后的一段时间。

·不连续接收HARQ重传的下行定时器(DRX-HARQ-RetransmisionTimerDL),例如该HARQ重传的下行定时器的时长可以为2ms等整数时长,本文不对该时长做限定,该HARQ重传的下行定时器时长表示UE接收到下行重传的最大等待时长。
·不连续接收的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)的环回时延的上行定时器(DRX-HARQ-RTT-TimerUL),例如该环回时延的上行定时器的时长可以为1ms等整数时长,本文不对该时长做限定,该环回时延的上行定时器的时长表示UE的媒体接入控制(medium access control,MAC)实体期望网络调度HARQ重传的最小等待时间。

·不连续接收的持续时间的开始偏移量(DRX-StartOffset),例如该开始偏移量可以为0ms等整数时长,本文不对该时长做限定,该开始偏移量表示DRX周期开始的子帧。
·不连续接收的持续时间的时隙偏移量(DRX-SlotOffset),例如该时隙偏移量可以为0ms等整数时长,本文不对该时长做限定,该时隙偏移量表示DRX周期开始的子帧的开始时隙。
接入网设备可以通过RRC消息将该DRX配置参数信息发送给UE,也可以通过其他消息将该DRX配置参数信息发送给UE。UE可以使用上述DRX配置参数信息对DRX进行初始配置,然后在根据SPS的配置参数信息确定DRX的活动时间。
SPS传输模式用于下行传输,对其对应的上行传输模式是授权(configured grant,CG)传输模式,同理,DRX的活动时间也可以基于CG的配置参数信息确定。应理解,基于CG的配置参数信息确定DRX的活动时间的方法与基于SPS的配置参数信息确定DRX的活动时间的方法为两套独立的方法,在执行两套方法时,两套方法互不影响,两套方法可以同时执行,也可以单独执行。
其中,步骤401可以替换为:S401接入网设备向UE发送CG的配置参数信息。
接入网设备向UE发送CG配置参数信息,该CG配置参数信息指示第一CG的时域资源或第二CG的时域资源中的一项或多项。CG分为CG type1和CG type2。CG type1类型的参数全部由RRC消息配置,CG type2的周期由RRC配置,时频资源由PDCCH的DCI配置,一次配置后UE可以周期性使用。具体用法可参考TS 38.321。由于XR数据的周期为非整数周期,所以可以配置多套整数周期的CG,来传输非整数周期的XR的上行数据。本文中的第一CG或第二CG只是用于区分CG,不代表只有一个或两个CG,可以有多于两个CG的配 置,这里不对CG的数量作限定。例如XR的数据以每秒60帧为例,即16.66ms,可以配置三套周期为50ms的SPS来传输周期为16.66ms的XR数据。该三套周期分别为第一CG、第二CG、第三CG。接入网设备向UE发送CG配置参数信息,该SPS配置参数信息指示第一CG的时域资源或第二CG的时域资源或第三CG的时域资源中的一项或多项。CG的配置参数信息可以包括如下参数的中一项或多项:CG周期,CG索引号,CG时域资源位置等。
步骤402可以替换为:S402基于CG配置参数信息确定DRX活动时间
可选地,该DRX活动时间可以包括该CG配置参数信息所指示的上述第一CG的时域资源或第二CG的时域资源中的一项或多项。如果配置了三套CG,则该DRX活动时间可以为该CG配置参数信息所指示的上述第一CG的时域资源、第二CG的时域资源或第二CG的时域资源中的一项或多项。应理解,本文中的第一CG或第二CG只是用于区分CG,不代表只有一个或两个CG,可以有多于两个CG的配置,这里不对CG的数量作限定。
可选地,该DRX活动时间可以通过CG的时域资源的起始时隙确定。示例性地,该DRX活动时间包括第一计时器的运行时间,在第一时间或第二时间中的一项或多项启动该第一计时器,该第一时间包括该第一CG的时域资源的起始时隙的第一符号,或,该第一CG的时域资源的结束时隙的下一个符号,或,该第一CG的时域资源的结束时隙的下一个时隙的第二符号,该第二时间包括所述第二CG的时域资源的起始时隙的第一符号,或,该第二CG的时域资源的结束时隙的下一个符号,或,该第二CG的时域资源的结束时隙的下一个时隙的第二符号。该第一计时器包括DRX持续(on-duration)计时器。应理解,该起始时隙的第一符号可以表示起始时隙的第一个符号,或其他符号,比如基于协议约定或基于接入网设备配置的其他符号。同理,下一个时隙的第二符号可以表示下一个时隙的第二个符号,或其他符号,比如基于协议约定或基于接入网设备配置的其他符号。
可选地,该DRX活动时间可以通过在CG的时域资源确定。示例性地,该DRX活动时间包括第二计时器的运行时间,在第三时间或第四时间中的一项或多项启动所述第二计时器,无论是否在该第一CG的时域资源传输数据,所述第三时间包括在第一CG的时域资源结束的的第三符号,无论是否在该第二CG的时域资源传输数据,该第四时间包括在第二CG的时域资源结束的第四符号。该第二计时器包括DRX on-duration计时器,DRX非激活(Inactivity)计时器,或,DRX上行重传计时器中的至少一项。该第三符号包括所述在第一CG的时域资源结束后的第一个符号或第一个时隙,或,所述第三符号包括在所述在第一CG的时域资源结束后的第一个符号或第一个时隙上启动第三计时器,所述第三计时器超时后的第一个符号或第一个时隙。该所述第四符号包括在所述在第二CG的时域资源结束后的第一个符号或第一个时隙上启动第三计时器,所述第三计时器超时后的第一个符号或第一个时隙。
DRX活动时间与启动时间和运行时长有关,运行时长可以为DRX on-duration计时器,DRX非激活(Inactivity)计时器,或,DRX上行重传计时器的时长,也可以为接入网设备配置的时长,这里运行时长的确定方式不做限制。
应理解,该第一数据或该第二数据可以包括XR的下行数据,也可以包括XR对应的下行信令,也可以包括XR的上行数据,还可以包括XR对应的上行信令。
本申请实施例提供的方法可以通过SPS的配置参数信息或CG的配置参数信息确定DRX的活动时间,基于该方法,可以使得DRX的活动时间可以更灵活,从而可以使DRX支持XR场景,UE可以节省功耗。
基于图4所对应的本申请实施例,请参见图5,图5示出了根据本申请实施例的通信方法500示意性流程图,在图5所示出的通信方法中,涉及接入网设备和用户设备。该方法500 包括但不限于如下步骤:
S501接入网设备向用户设备(UE)发送DRX配置参数信息。
接入网设备向UE发送DRX配置参数信息,该DRX配置参数信息可以包括如下参数中的一种或多种:不连续接收的长周期、不连续接收的短周期、不连续接收的持续时间定时器、不连续接收的非活动定时器、不连续接收的HARQ环回时延的下行定时器、不连续接收HARQ重传的下行定时器、连续接收的持续时间的开始偏移量以及不连续接收的持续时间的时隙偏移量。各个参数的具体含义可参见本文步骤S403的相关描述,这里不再赘述。可以理解的是,和图4中的针对S403的描述类似,S501也是可选的。
S502接入网设备向UE发送SPS配置参数信息。
接入网设备向UE发送SPS配置参数信息,该SPS配置参数信息指示第一SPS的时域资源或第二SPS的时域资源中的一项或多项。由于XR数据的周期为非整数周期,所以可以配置多套整数周期的SPS,来传输非整数周期的XR的数据。本文中的第一SPS或第二SPS只是用于区分SPS,不代表只有一个或两个SPS,可以有多于两个SPS的配置,这里不对SPS的数量作限定。示例性地,如图6所示,XR的数据以每秒60帧为例,即XR的数据周期为16.66ms,为了匹配XR的非整数周期的数据,可以配置三套周期为50ms的SPS来传输周期为16.66ms的XR数据。该三套周期分别为第一SPS、第二SPS、第三SPS。第一SPS的时域资源为SF0、SF50和SF100,第二SPS的时域资源为SF17和SP67,第三SPS的时域资源为SF34和SF84。该SPS的配置参数信息可以包括如下参数的中一项或多项:SPS周期,SPS索引号,SPS时域资源位置等。所述第一SPS的时域资源的周期和所述第二SPS时域资源的周期相同。应理解图6中仅仅示出了SF0到SF100的示例,可以有多于SF100的子帧,这里对此不做限定。
可选地,接入网设备向UE发送指示信息,该指示信息指示DRX活动时间与SPS时域资源相关。该指示信息也可指示SPS的参数,如SPS的周期,SPS的索引号以及SPS时域资源位置等中的一项或多项。
其中,SPS的时域、频域位置资源信息可以通过PDCCH的DCI来配置。SPS的周期可以通过RRC消息来配置。
S503UE基于SPS资源的起始时隙或结束时隙确定DRX活动时间的起始时间。
UE可以基于接收到的SPS资源的起始时隙确定DRX活动时间的起始时间。该DRX活动时间包括第一计时器的运行时间,UE可以在第一时间或第二时间中的一项或多项启动所述第一计时器,该第一时间包括该第一SPS的时域资源的起始时隙的第一符号,或,所述第一SPS的时域资源的结束时隙的下一个符号,或,所述第一SPS的时域资源的结束时隙的下一个时隙的第二符号,所述第二时间包括所述第二SPS的时域资源的起始时隙的第一符号,或,所述第二SPS的时域资源的结束时隙的下一个符号,或,所述第二SPS的时域资源的结束时隙的下一个时隙的第二符号。该第一计时器包括DRX持续计时器。应理解,接入网设备可以根据XR数据的周期配置大于两套的SPS资源,本文不对SPS的数量做限制。
示例性地,如图6所示,XR的数据以每秒60帧为例,即XR的数据周期为16.66ms,为了匹配XR的非整数周期的数据,接入网设备可以配置三套周期为50ms的SPS来传输周期为16.66ms的XR数据。首先,UE接收第一SPS配置的参数:SPS索引号为1,周期为50ms,UE接收第二SPS配置的参数:SPS索引号为2,周期为50ms,UE接收第三SPS配置的参数:SPS索引号为3,周期为50ms。其次,UE还可以接收第一SPS、第二SPS以及第三SPS的资源信息,SPS的资源的时域位置对应的系统帧号(system frame number,SFN)和时隙(slot) 分别记为SFN start time和slot start time,UE可以通过如下公式确定第N块SPS资源出现的时域位置,即UE可以通过如下公式确定第N块SPS资源出现在哪个SFN,以及这个SNF的哪个slot内,也即,第N块SPS资源出现在哪个SFN,以及这个SNF的哪个slot内,满足以下公式所体现的关系,可以理解的是,这种关系也可以通过其他方式来体现,比如,表格,或是,字符串流。
(numberOfSlotsPerFrame×SFN+slot number in the frame)
=[(numberOfSlotPerFrame×SFN start time+slot start time)+N
×periodicity×numberOfSlotsPerFrame/10]modulo(1024
×numberOfSlotsPerFrame)
其中,numberOfSlotsPerFrame为一个无线帧中包括的slot数目,SFN为系统帧号,slot number in the frame为该时隙在SFN中的序号,SFN start time和slot start time为SPS的资源的时域位置对应的系统帧号和时隙,N表示第N块SPS资源,periodicity为SPS的周期,moduolo表示取模操作。其中,Slot start time可以通过PDCCH的DCI来配置。Slot start time是所述DCI所在的SFN start time
UE可以按上述方法根据每套SPS资源的SFN start time和slot start time和SPS周期确定每套SPS资源第N次周期性出现的时域位置SFN以及SPS资源的起始时隙slot number in the frame。UE在确定完SPS资源的起始时隙后,再基于该SPS的起始时隙确定DRX活动时间的第一计时器的启动时间,该第一计时器包括第一时间、第二时间以及第三时间。
若接入网设备指示UE在第一SPS资源的时域位置监听,则UE将在第一SPS的时域资源的起始时隙的第一符号作为第一时间;若接入网设备指示UE在第二SPS资源的时域位置监听,则UE将在第二SPS的时域资源的起始时隙的第一符号作为第二时间;若接入网设备指示UE在第三SPS资源的时域位置监听,则UE将在第三SPS的时域资源的起始时隙的第一符号作为第三时间。UE在第一时间、第二时间或第三时间的一项或多项启动所述第一计时器。应理解,该起始时隙的第一符号可以表示起始时隙的第一个符号。
可选地,UE还可以根据如下公式基于SPS的起始时隙确定DRX活动时间的起始时间,也即,DRX活动时间和SPS的起始时隙满足以下公式所体现的关系,可以理解的是,这种关系也可以通过其他方式来体现,比如,表格,或是,字符串流:
[(SFN×10)+subframe number]modulo(drx_LongCycle)=drx_StartOffset
其中,SFN为系统帧号,subframe number为子帧号,drx_LongCycle为DRX的周期,drx_StartOffset为DRX周期开始的子帧。将DRX长周期drx_LongCycle设置为上述SPS的周期,drx_StartOffset可以根据上述SPS的slot start time来确定,例如,drx_StartOffset可以为slot start time/numberOfSlotsPerSubFrame的值取整数。UE可以通过drx_StartOffset确定SPS资源周期性出现的时域位置SFN以及SPS资源的子帧号subframe number,UE上述确定的SFN和subframe number来确定DRX活动时间的起始时间。应理解,接入网设备或UE可以先通过DRX的参数配置信息进行初始配置,然后再根据SPS的参数配置信息对DRX的相应参数进行重新配置,进而确定DRX的活动时间。
可选地,SPS的开始时隙或结束时隙可以作为SPS资源所在服务小区所在的DRX组的所有服务小区的DRX活动时间的开始时间。示例性地,如图7所示,服务小区1处于基于SPS配置的DRX活动时间,同属于第一DRX组的所有服务小区,图中包括服务小区2,服务小区3,服务小区4,都处于DRX活动时间。服务小区1处于的DRX活动状态不会影响 第二DRX组内的服务小区。

可选地,SPS的开始时隙或结束时隙可以作为SPS资源所在服务小区所在的DRX组的所有服务小区的DRX活动时间的开始时间。示例性地,如图7所示,服务小区1处于基于SPS配置的DRX活动时间,同属于第一DRX组的所有服务小区,图中包括服务小区2,服务小区3,服务小区4,都处于DRX活动时间。服务小区1处于的DRX活动状态不会影响第二DRX组内的服务小区。
