一种DRX控制方法及装置
相关申请的交叉引用
本申请要求在2020年04月10日提交中国专利局、申请号为202010281671.5、申请名称为“一种DRX控制方法及装置”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,尤其涉及一种不连续接收(Discontinuous Reception,DRX)控制方法及装置。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)协议所规定的新无线电(new radio,NR)系统中,无线传输的频率范围可以分为FR1频段和FR2频段,其中FR1频段的频率范围是410MHz-7125MHz,FR2频段的频率范围是24.25GHz-52.6GHz。在载波聚合(carrier aggregation,CA)场景,一个终端设备可以被配置多个载波(carrier),被配置的每个载波称为一个子载波(component carrier,CC)。终端设备可以被配置FR1内的子载波,或被配置FR2内的子载波,或同时被配置FR1内的子载波和FR2内的子载波。
实际情况中,终端设备的每个服务小区不一定都有数据传输的需求,如果终端设备在所有服务小区上同时维持DRX激活时间会消耗不必要的功耗。为了降低CA场景配置DRX时的功率损耗,3GPP提出同一个终端设备可以配置2个DRX(如第一DRX、第二DRX),每个DRX对应一组DRX参数。
然而,当一个DRX(如第一DRX)处于DRX激活时间,而另一个DRX(如第二DRX)处于DRX非激活时间时,如果有更多的数据到来,网络也只能在第一DRX对应的服务小区上传输数据,而不能在第二DRX对应的服务小区上传输数据,不利于系统吞吐量的提升,会增加数据时延。

具体实施方式
终端设备在无线电资源控制(Radio Resource Control,RRC)连接态(Connected)可以配置不连续接收(Connected-Discontinuous Reception,C-DRX或DRX)机制,使得终端设备每间隔一定的周期进入DRX的持续时间(ON Duration),在ON Duration内监听物理下行控制信道(Physical Downlink Control Channel,PDCCH)和收发数据,而在其他时候可以进入睡眠状态,不用去监听PDCCH,从而节省终端设备功耗。
当终端设备配置DRX时,终端设备的状态可以分为DRX激活(active)态和DRX非激活(non-active)态(或者称为睡眠状态),终端设备处于DRX Active态的时间称为激活时间(active time),终端设备处于DRX non-active态的时间称为非激活时间(non-active time)。当终端设备处于DRX激活时间时,终端设备会持续监听PDCCH。如果终端设备离开DRX激活态,即进入睡眠状态,则终端不去监听PDCCH,可以节省功耗。
当以下任意一个定时器在运行时,终端设备即处于DRX激活态(即处于DRX激活时间):
DRX持续时间定时器(drx-onDurationTimer);
DRX非激活定时器(drx-InactivityTimer);
DRX下行重传定时器(drx-RetransmissionTimerDL);
DRX上行重传定时器(drx-RetransmissionTimerUL);
随机接入竞争解决定时器(ra-ContentionResolutionTimer)。
此外,DRX激活时间还包括其他情况,例如:终端设备在PUCCH上发送了调度请求(Scheduling Request,SR)之后的等待期间;终端设备在成功接收到基于非竞争(non-contention based)随机接入的随机接入响应(Random Access Response,RAR)之后还未收到指示新传的PDCCH期间。
图1为配置了C-DRX机制的终端设备的状态示意图。C-DRX周期的开始时刻,终端会首先进入ON Duration,同时开启定时器drx-onDurationTimer(该定时器开始运行即进入DRX的激活时间),如果在drx-onDurationTimer运行期间,终端设备收到PDCCH指示下行或上行新的数据传输,则终端设备会开启(或重启)定时器drx-InactivityTimer,使得终端设备一直处于DRX激活态(可以理解为,终端设备原本处于激活态的时间长度为ON Duration的时间长度,运行drx-InactivityTimer可以延长终端设备处于激活态的时间),直到drx-InactivityTimer定时器超时,或者终端设备收到相关的媒体接入控制(Medium access control,MAC)控制单元(control element,CE)信令使该drx-InactivityTimer定时器提前停止,终端设备才结束激活时间,进入非激活时间(即终端设备从激活状态进入睡眠状态)。容易理解,这里描述的DRX持续时间 (ON Duration)表示一个时间段,是由定时器drx-onDurationTimer所决定的,持续时间的长度等于网络设备配置的定时器drx-onDurationTimer的大小。
drx-InactivityTimer一般是在用于指示新传数据的PDCCH之后第一个符号启动或重启。如图2所示,图2中PDCCH用于调度新的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)传输。
如上所述,当终端设备处于DRX激活态时,会持续监听PDCCH,如果终端设备离开了DRX激活态(进入睡眠状态),则不去监听PDCCH。因此在ON Duration期间运行drx-InactivityTimer可以使得终端设备更久地处于DRX激活态,持续监听PDCCH,直至drx-InactivityTimer停止运行。
第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)协议所规定的新无线电(new radio,NR)系统中,无线传输的频率范围分为FR1频段和FR2频段,其中FR1频段的频率范围是410MHz-7125MHz,FR2频段的频率范围是24.25GHz-52.6GHz。FR2频段位于高频频段,通常被称为毫米波(millimeter wave,mmWave)。在载波聚合(carrier aggregation,CA)场景,一个终端设备可以被配置多个载波(carrier),被配置的每个载波称为一个子载波(Component Carrier,CC)。终端设备可以被配置FR1内的子载波,或被配置FR2内的子载波,或同时被配置FR1内的子载波和FR2内的子载波。
终端设备在CA场景比非CA场景功耗较高,尤其是FR1和FR2之间的载波聚合。主要原因如下:CA场景工作带宽较高,当终端设备工作在异频带CA时,终端设备要开启多个射频链路连接异频带的多个子载波,导致终端设备在单位时间内要执行更多的数据监测和译码。而在FR2内的高频子载波上,终端设备还要维持和基站之间的连接波束,所以终端设备还需要执行波束管理测量。
当配置DRX时,终端设备在DRX激活时间具有较高的功率损耗。如上背景所述,终端设备要周期的进入DRX激活时间监听PDCCH,监听PDCCH、接收和译码PDSCH或发送PUSCH消耗较高的功率。当数据较稀疏时,网络设备并没有发送PDCCH调度数据,所以终端设备监测PDCCH会消耗不必要的功耗。此外,终端设备在DRX激活时间还要执行一些测量和上行发送,比如信道状态信息(channel state information,CSI)/层1参考信号接收功率(layer 1-reference signal received power,L1-RSRP)测量、无线资源管理(radio resource management,RRM)测量、CSI/L1-RSRP上报、探测参考信号(sounding reference signal,SRS)发送等。
终端设备在CA场景下配置DRX时的功耗较高。网络设备一般只配置一套DRX参数,终端设备的一个媒体接入控制实体(MAC entity)只运行一套DRX参数,终端设备的DRX状态适用于CA下的所有服务小区(应理解,本文中涉及的“服务小区”又可简称为“小区”)。如果终端设备处于DRX active time,则终端设备所有激活的服务小区都处于DRX激活时间,终端设备在所有激活的服务小区上都要监听PDCCH。但是实际情况中,不一定每个服务小区都有数据传输的需求,所以终端设备在所有服务小区上同时维持DRX激活时间会消耗不必要的功耗。
为了降低CA场景配置DRX时的功率损耗,3GPP提出在CA场景配置2个DRX(或者说配置2个DRX模式),每个DRX对应一组DRX参数,终端设备在不同DRX配置上的状态相互独立(可理解为,终端设备独立运行每个DRX模式)。本文中可以将 被配置同一DRX的一个或多个小区称为一个DRX组,例如将配置第一DRX的一个或多个小区称为第一DRX组,将配置第二DRX的一个或多个小区称为第二DRX组。如果一个小区被配置第一DRX,则可以认为该小区被配置到第一DRX组,如果一个小区被配置第二DRX,则可以认为该小区被配置到第二DRX组。
应理解,在本文中“配置DRX”、“配置DRX模式”、“配置DRX参数”以及“配置DRX组”等描述之间可以相互解释,比如可以指代相同的含义。
进一步的,第一DRX和第二DRX的DRX参数可以不同。例如这两个DRX可以配置不同的drx-onDurationTimer和/或不同的drx-InactivityTimer。例如,第一DRX配置drx-onDurationTimer-1和drx-InactivityTimer-1,第二DRX配置drx-onDurationTimer-2和drx-InactivityTimer-2。如果网络配置其中一个DRX的这两个定时器中的其中一个或两个的值分别比另一个DRX的值小,例如,drx-onDurationTimer-2<drx-onDurationTimer-1,drx-InactivityTimer-2<drx-InactivityTimer-1,则容易理解,当没有数据传输或者第二DRX对应的服务小区上的数据传输较稀疏时,第二DRX的DRX激活时间比第一DRX的激活时间短,所以终端设备在第二DRX的子载波上可以更快的进入DRX非激活时间,进而降低配置第二DRX的子载波上的功耗损耗,如图3所示,图3中,FR1内的子载波配置第一DRX,FR2内的子载波配置第二DRX。
除了drx-onDurationTimer和drx-InactivityTimer这两个定时器外,第一DRX和第二DRX的其他DRX参数可以相同或不同,可以独立配置或者共享DRX参数,本发明不做限制。例如,两个DRX可以共享其他的DRX参数,具有相同的长周期(Long DRX cycle)参数,相同的短周期参数(short DRX cycle)等。
如上所述,当终端设备配置有2个DRX(或者说2个DRX组、2组DRX参数等)时,2个DRX可以配置相互独立的drx-onDurationTimer和/或drx-InactivityTimer。终端设备的两个DRX独立控制对应的drx-onDurationTimer和/或drx-InactivityTimer,所以可以使终端设备在两个DRX的DRX状态不同。这样,和一套DRX配置相比,可以更灵活地控制终端设备的DRX激活时间,达到节省功耗的目的。
但是,当其中一个DRX(例如第一DRX)的服务小区(cell)位于DRX激活时间,另一个DRX(第二DRX)的服务小区位于DRX非激活时间时,如果有更多的数据到来,网络也只能在第一DRX对应的小区上传输数据,而不能在第二DRX对应的小区上传输数据。如图4所示,终端设备被配置了FR1小区和FR2小区的载波聚合,FR1小区配置第一DRX(即在第一DRX组),FR2小区配置第二DRX(即在第二DRX组)。当FR1小区在DRX激活时间,FR2小区不在DRX激活时间时,如果有更多的数据到来时,此时FR2小区的第二DRX在DRX非激活时间,所以数据只能在另一个DRX组内的FR1小区上传输。如果网络设备想在FR2小区传输数据,只能等到第二DRX的下一个DRX周期。这样,不利于系统吞吐量的提升,会增加数据时延。
鉴于此,本申请实施例提供一种DRX控制方法及装置,用以在终端设备配置多个DRX时,有效控制不同DRX的激活时间,实现既可以节省功耗,又不降低终端设备的吞吐量和增加终端设备的数据时延。
应理解,本申请实施例的技术方案可以应用于各种通信系统,例如第四代(4th Generation,4G)通信系统、第五代(5th Generation,5G)通信系统、机器类通信(Machine  Type Communication,MTC)系统、设备到设备(device to device,D2D)系统、物联网(Internet of Things,IoT)系统、车联网(vehicle-to-everything,V2X)系统,窄带物联网(Narrow Band Internet of Things,NB-IoT)系统、以及未来通信发展中出现的新的通信系统等,只要该通信系统中通信实体可以配置多套DRX参数即可,其中一个DRX对应一套DRX参数。

以上介绍了本申请实施例适用的通信系统,接下来结合附图介绍本申请实施例提供的DRX控制方法。
应理解,本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a和b,a和c,b和c,或a和b和c。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。例如,第一优先级准则和第二优先级准则,只是为了区分不同的准则,而并不是表示这两种准则的内容、优先级或者重要程度等的不同。
如图6所示,本申请实施例提供一种DRX控制方法,可以应用于图5所示的通信系统。该方法包括:
S601、网络设备在终端设备的第一服务小区上发送指示信息,终端设备接收该指示信息,其中第一服务小区配置第一DRX。
S602、终端设备根据指示信息开始或延长或结束第二服务小区的DRX激活时间,其中第二服务小区配置第二DRX。
具体的,在本申请实施例中,终端设备可以同时驻留在网络设备的多个服务小区(例如包括一个主服务小区,一个或多个辅服务小区),其中不同的服务小区在不同的子载波上。
网络设备可以配置至少两个DRX,该至少两个DRX包括上述第一DRX和上述第二DRX,当然还可能包括其它DRX。
终端设备的每个服务小区配置一个DRX,其中不同服务小区配置的DRX可以相同或不同。
其中,配置同一DRX的服务小区可以被称为一个DRX组,也即位于同一DRX组的小区配置相同的DRX(即配置相同的DRX参数)。
示例性的,配置第一DRX的服务小区为第一DRX组,第一DRX组包括上述第一服务小区,因此上述第一服务小区配置第一DRX又可以理解为第一服务小区被配置到第一DRX组;配置第二DRX的服务小区为第二DRX组,第二DRX组包括上述第二服务小区, 同理,上述第二服务小区配置第二DRX又可以理解为第二服务小区被配置到第二DRX组。
在本申请实施例中,不同DRX的DRX激活时间可以不同,也即配置不同DRX的服务小区的激活时间不同。例如,配置上述第一DRX的服务小区(如第一服务小区)的激活时间和配置上述第二DRX的服务小区(如第二服务小区)的激活时间可以不同。
示例性的,不同DRX可以对应不同的定时器。例如,第一DRX对应drx-onDurationTimer-1和drx-InactivityTimer-1,第二DRX对应drx-onDurationTimer-2和drx-InactivityTimer-2。drx-onDurationTimer-1和drx-onDurationTimer-2的运行时长可以不同(即第一DRX和第二DRX的持续时间不同),例如7A所示,DRX持续时间定时器-1(drx-onDurationTimer-1)的时长大于DRX持续时间定时器-2(drx-onDurationTimer-2)的时长。
应理解,这里配置不同DRX的激活时间不同,包括激活时间的开始时刻和/或结束时刻不同,比如不同DRX的激活时间存在部分重叠或者没有重叠。
示例性的,参见图7A或图7B或图7C或图7D,终端设备的配置有两个DRX,两个DRX具有相同的DRX周期,每个周期内两个DRX的ON Duration的开始时刻相同(即drx-onDurationTimer-1和drx-onDurationTimer-2的开启时刻相同),但持续时间ON Duration的结束时刻不同(即drx-onDurationTimer-1和drx-onDurationTimer-2的结束时刻不同)。
示例性的,不同DRX的drx-onDurationTimer的值也可以配置成相同,这样,在没有数据传输时,不同DRX的激活时间都是其对应的持续时间,不同DRX的持续时间是相同的,此时可以认为,不同DRX的激活时间存在部分重叠。当有数据传输时,不同DRX对应的服务小区上数据大小和数据到达时刻不同,所以不同DRX的drx-InactivityTimer的启动/结束时刻不同,这样,不同DRX的激活时间的结束时刻就会不同。
应理解,配置同一DRX(即位于同一个DRX组内)的服务小区的DRX激活时间相同。当描述一个服务小区的DRX激活时间时,其含义就是在描述该服务小区所配置DRX的DRX激活时间。一个服务小区的DRX状态改变(例如开始/延长/结束DRX激活时间)时,该服务小区所配置DRX的DRX状态也发生相同的改变,与该服务小区配置同一DRX的其他服务小区的DRX状态也发生相同的改变。
一种可能的设计是,低频子载波的服务小区所对应的DRX的drx-onDurationTimer定时器的值和/或drx-InactivityTimer定时器的值大于高频子载波的服务小区所对应的DRX的相应的定时器的值。例如,子载波频段在FR1的服务小区所对应的DRX的drx-onDurationTimer定时器的值和/或drx-InactivityTimer定时器的值大于子载波频段在FR2的服务小区所对应的DRX的相应的定时器的值。因为系统工作在高频段时的功耗较高,通过将高频段的drx-onDurationTimer定时器的值和/或drx-InactivityTimer定时器配置成较小值,可以将对应的DRX激活时间缩短,可以降低高频段服务小区对应的DRX的功耗损耗,同时网络设备又可以通过第一DRX发送指示信息灵活地控制第二DRX的激活时间的开始、延长或结束等,可以兼顾数据的传输需求,降低数据时延,提升系统吞吐量。
应理解的是,本申请不限制不同DRX对应的drx-onDurationTimer和/或drx-InactivityTimer的取值,不同DRX对应的drx-onDurationTimer和/或drx-InactivityTimer的取值可以配置成相同或不同。例如,子载波频段在FR2的服务小区所对应的DRX的drx-onDurationTimer和/或drx-InactivityTimer和子载波频段在FR1的服务小区所对应的相 应的定时器也可以配置成相同的值。
在本申请实施例中,指示信息可以具备以下至少一种功能:
1)指示终端设备开始终端设备的第二服务小区的DRX激活时间;
2)指示终端设备延长终端设备的第二服务小区的DRX激活时间;
3)指示终端设备结束终端设备的第二服务小区的DRX激活时间。
应理解,当网络设备实际发送指示信息时,网络设备发送的该指示信息指示其中一种功能,例如用于指示终端设备开始或延长或结束终端设备的第二服务小区的DRX激活时间。
应理解,网络设备发送的指示信息具有如上的哪些功能,可以是协议预先定义好,或者通过网络设备配置或指示。
以下,对指示信息的上述三种功能的具体实现分别详细进行介绍。
方式1、指示信息指示终端设备开始终端设备的第二服务小区的DRX激活时间。
如图7A所示,网络设备可以在第二服务小区的DRX非激活时间,在第一服务小区上发送第一指示信息,用于指示终端设备启动第二DRX对应的DRX非激活定时器(即drx-InactivityTimer-2)。相应的,终端设备在第二服务小区的DRX非激活时间在第一服务小区上接收第一指示信息,终端设备根据第一指示信息在第二服务小区的DRX非激活时间启动第二DRX对应的DRX非激活定时器,以结束第二服务小区的DRX非激活时间,开始第二服务小区的DRX激活时间。
结合图7A,上述方式1的具体实现流程可以包括以下几个步骤:
步骤1、网络设备发送第一配置信息和第二配置信息,终端设备接收第一配置信息和第二配置信息。
其中,第一配置信息包括第一DRX配置信息和第二DRX配置信息,第一DRX配置信息用于配置第一DRX的DRX非激活定时器,第二DRX配置信息用于配置第二DRX的DRX非激活定时器。
应理解,第一DRX配置信息还可以用于配置第一DRX的除DRX非激活定时器外的其他DRX参数,第二DRX配置信息还可以用于配置第二DRX的除DRX非激活定时器外的其他DRX参数。
第二配置信息用于将第一小区配置到第一DRX组,以及将第二小区配置到第二DRX组。可选的,网络设备可以给第一小区配置第一DRX组的组标识,给第二小区配置第二DRX组的组标识。
应理解,第一DRX组(或第一DRX组的组标识)和第一DRX配置信息是关联的,第二DRX组(或第二DRX组的组标识)和第二DRX配置信息是关联的,将第一小区配置到第一DRX组也就是将第一小区配置第一DRX,将第二小区配置到第二DRX组也就是将第二小区配置第二DRX。
相应的,终端设备根据第一配置信息配置第一DRX的DRX非激活定时器和第二DRX的DRX非激活定时器,根据第二配置信息将第一小区配置到第一DRX组和将第二小区配置到第二DRX组。
可选的,终端设备可以给第一小区配置第一DRX组的组标识以将第一小区配置到第一DRX组,给第二小区配置第二DRX组的组标识以将第二小区配置到第二DRX组。
步骤2、在第一DRX组处于DRX激活时间、且第二DRX组处于DRX非激活时间时,网络设备在第一小区上发送第一指示信息,终端设备在第一小区上接收该第一指示信息。
其中,第一指示信息用于指示终端设备在第二DRX组启动第二DRX的DRX非激活定时器。
步骤3、终端设备启动第二DRX的DRX非激活定时器,使得终端设备在第二DRX组开始处于DRX激活时间。
可选的,终端设备如果在第二服务小区的DRX激活时间,在配置第二DRX的任意一个服务小区上接收到用于指示新的数据传输的物理下行控制信道PDCCH,则可以启动或重启第二DRX对应的DRX非激活定时器,以延长第二DRX的激活时间。
应理解,当终端设备在第二服务小区处于DRX激活时间时,网络设备不需要在第一服务小区发送第一指示信息,只需要在配置第二DRX的任意一个服务小区上发送用于指示新的数据传输的物理下行控制信道PDCCH,就可以延长终端设备的第二DRX的DRX激活时间。
另外,在第一服务小区的DRX激活时间,终端设备如果在配置第一DRX的任意一个服务小区上接收到用于指示新的数据传输的物理下行控制信道PDCCH,则启动或重启第一DRX对应的DRX非激活定时器,以延长第一DRX的激活时间。
方式2、指示信息用于指示终端设备延长终端设备的第二服务小区的DRX激活时间。
具体的,网络设备可以在第二服务小区的DRX激活时间,在第一服务小区上发送第二指示信息,第二指示信息用于指示终端设备启动或重启第二DRX对应的DRX非激活定时器(即drx-InactivityTimer-2)。相应的,终端设备在第二服务小区的DRX激活时间在第一服务小区上接收第二指示信息,并根据第二指示信息,在第二服务小区的DRX激活时间,启动或重启第二DRX对应的DRX非激活定时器,以延长第二服务小区的DRX激活时间。
更具体地,第一服务小区和第二服务小区(或者说第一DRX组和第二DRX组)都位于DRX激活时间,此时终端设备收到第二指示信息时,如果drx-InactivityTimer-2未运行,则终端设备启动drx-InactivityTimer-2,如图7B所示;如果drx-InactivityTimer-2已运行,则终端设备重启drx-InactivityTimer-2,如图7C所示。
在这种情况下,终端设备在第二DRX组不再根据判断是否收到指示新传的PDCCH来决定是否启动或重启drx-InactivityTimer-2。即使UE在第二DRX组的服务小区上收到指示新传的PDCCH,但未收到第二指示信息指示终端启动/重启drx-InactivityTimer-2,终端也不启动/重启drx-InactivityTimer-2。
结合图7B和图7C,上述方式2的具体实现流程可以包括以下几个步骤:
步骤1、网络设备发送第一配置信息和第二配置信息,终端设备接收第一配置信息和第二配置信息。相应的,终端设备根据第一配置信息配置第一DRX的DRX非激活定时器和第二DRX的DRX非激活定时器,根据第二配置信息将第一小区配置到第一DRX组和将第二小区配置到第二DRX组。
这里步骤1的具体实现方式可以参考上述方式1中的步骤1的具体实现方式,这里不再赘述。
步骤2、在第一DRX组处于DRX激活时间、且第二DRX组也处于DRX激活时间 时,网络设备在第一小区上发送第二指示信息,终端设备在第一小区上接收该第二指示信息。
步骤3、终端设备根据第二指示信息启动或重启第二DRX的DRX非激活定时器,使得终端设备延长第二服务小区的DRX激活时间。
应理解的是,上述方式1和方式2可以相互结合实施,当方式1和方式2结合实施时,终端设备在第一DRX组处于DRX激活时间、第二DRX组处于DRX非激活时间时,终端设备根据第一指示信息开启第二DRX的DRX非激活定时器,以开始第二DRX组的激活时间;如果终端设备在第一DRX组处于DRX激活时间、第二DRX组也处于DRX激活时间,终端设备根据第二指示信息,开启/重启第二DRX的DRX非激活定时器,以延长第二DRX组的激活时间。
类似的,对于第一服务小区的DRX激活时间,终端设备如果在配置第一DRX的任意一个服务小区上接收到用于指示新的数据传输的物理下行控制信道PDCCH,启动或重启第一DRX对应的DRX非激活定时器。
可选的,上述第一指示信息和第二指示信息实际上可以为相同的指示信息,终端设备基于接收指示信息的时间不同(即终端设备在第二DRX的非激活时间或激活时间接收指示信息),可以使得相同的指示信息实现不同的指示功能(前者可以开始第二DRX的激活时间,后者可以延长第二DRX的激活时间)。
方式3、指示信息用于指示终端设备结束终端设备的第二服务小区的DRX激活时间。
如图7D所示,网络设备可以在第二服务小区的DRX激活时间,在第一服务小区上发送第三指示信息,第三指示信息用于指示终端设备停止第二DRX对应的DRX非激活定时器(即drx-InactivityTimer-2)。相应的,终端设备在第二服务小区的DRX激活时间在第一服务小区上接收第三指示信息,然后根据第三指示信息,在第二服务小区的DRX激活时间,停止第二DRX对应的DRX非激活定时器,以结束第二服务小区的DRX激活时间,开始第二服务小区的DRX非激活时间。
结合图7D,上述方式3的具体实现流程可以包括以下几个步骤:
步骤1、网络设备发送第一配置信息和第二配置信息,终端设备接收第一配置信息和第二配置信息。相应的,终端设备根据第一配置信息配置第一DRX的DRX非激活定时器和第二DRX的DRX非激活定时器,根据第二配置信息将第一小区配置到第一DRX组和将第二小区配置到第二DRX组。
这里步骤1的具体实现方式可以参考上述方式1中的步骤1的具体实现方式,这里不再赘述。
步骤2、在第一DRX组处于DRX激活时间、且第二DRX组也处于DRX激活时间、且第二DRX的DRX非激活定时器处于运行状态时,网络设备在第一小区上发送第三指示信息,终端设备在第一小区上接收该第三指示信息。
步骤3、终端设备根据第三指示信息停止第二DRX的DRX非激活定时器,使得终端设备的第二服务小区的DRX激活时间结束,进入DRX非激活时间。
可选的,第三指示信息还可以用于指示终端设备停止第二DRX对应的DRX持续时间定时器(即drx-onDurationTimer-2)。
应理解,方式3可以和上述方式1结合实施(即采用方式1开启drx-InactivityTimer-2、 方式3停止drx-InactivityTimer-2),可以和上述方式2结合实施(即采用方式2开启/重启drx-InactivityTimer-2、方式3停止drx-InactivityTimer-2),还可以和上述方式1、2一起结合实施等(即采用方式1、2开启/重启drx-InactivityTimer-2、方式3停止drx-InactivityTimer-2),这里不做限制。
可选的,上述第三指示信息和上述第一/第二指示信息,可以通过同一个指示信息(为便于描述,这里称为第四指示信息)的不同状态实现。
示例1、终端设备在第一小区接收第四指示信息,当第四指示信息设置为第一状态且第二DRX组在DRX非激活时间时,终端设备在第二DRX组启动drx-InactivityTimer-2。当第四指示信息设置为第二状态且第二DRX组在DRX激活时间时,终端设备在第二DRX组停止drx-InactivityTimer-2。终端设备在第一小区处于DRX激活时间时,如果在第一DRX组的任意一个服务小区上收到指示新传的PDCCH,终端设备启动或重启drx-InactivityTimer-1。
示例2、终端设备在第一小区接收第四指示信息,当第四指示信息设置为第一状态且第二DRX组在DRX激活时间时,终端设备在第二DRX组启动或重启drx-InactivityTimer-2。当第四指示信息设置为第二状态且第二DRX组在DRX激活时间时,终端设备在第二DRX组停止第二DRX非激活定时器。终端设备在第一小区处于DRX激活时间时,如果在第一DRX组的任意一个服务小区上收到指示新传的PDCCH,终端设备启动或重启第一DRX非激活定时器(即drx-InactivityTimer-1)。
一种可能的设计是,第四指示信息的不同状态通过同一个信息比特的不同值来实现。例如,第四指示信息具体为DCI的第一比特位,第一比特位的值为0(或1)时表示第四指示信息设置为第一状态,第一比特位的值为1(或0)时表示第四指示信息设置为第二状态。
应理解,上述第三指示信息和上述第一/第二指示信息,也可以通过不同的指示信息实现。例如,上述第一/第二指示信息通过DCI承载,上述第三指示信息通过PDSCH承载。
本申请一种可能的实施方式中,网络设备可以通过在终端设备的任意一个DRX的服务小区上发送指示信息来指示终端设备的另一个DRX的服务小区的DRX状态。
在这种情况下,第一服务小区可以为终端设备的主服务小区,第二服务小区可以为终端设备的辅服务小区;或者,第一服务小区可以为终端设备的辅服务小区,第二服务小区可以为终端设备的主服务小区;或者,第一服务小区、第二服务小区均可以为终端设备的辅服务小区。
可选的,位于不同DRX组的小区之间(即配置不同DRX的服务小区)可以相互发送指示信息,来控制对方的DRX状态切换。
例如,在执行上述S602之后,终端设备还可以接收网络设备在终端设备的第三服务小区上发送的指示信息,其中网络设备在第三服务小区上发送的指示信息用于指示终端设备开始或延长或结束终端设备的第一服务小区的DRX激活时间,终端设备根据网络设备在第三服务小区上发送的指示信息,开始或延长或结束第一服务小区的DRX激活时间。其中,第三服务小区可以配置第二DRX,第三服务小区可以和第二服务小区是同一个小区,也可以是不同的小区,不做限定。
网络设备在一个DRX组中的具体哪一个或者多个服务小区发送如上所述指示信息,可以由协议预先定义好,或者通过网络设备发送配置信令或指示信令进行指示。
本申请另一种可能的实施方式中,网络设备可以通过在终端设备的主服务小区上发送指示信息来指示终端设备的一个或多个辅服务小区的DRX状态,而不能在辅服务小区上发送指示信息来指示主服务小区的DRX状态。在这种情况下,上述第一服务小区为终端设备的主服务小区,上述第二服务小区为终端设备的辅服务小区。
本申请另一种可能的实施方式中,网络设备可以在终端设备的一个DRX组内的一个或多个小区上,发送指示信息,用于指示其它所有DRX组对应的激活时间开始、延长或结束。例如,网络设备可以在上述第一服务小区上发送的指示信息用于指示终端设备开始或延长或结束至少两个DRX中除第一DRX外的其它DRX对应的服务小区的DRX激活时间,其它DRX包括第二DRX。
例如,网络设备将第一小区配置第一DRX,将第二小区配置第二DRX,将第三小区配置第三DRX。网络设备在第一小区发送第五指示信息,第五指示信息用于指示终端设备在第二小区开始、延长或结束DRX激活时间,同时用于指示终端设备在第三小区开始、延长或结束DRX激活时间。
网络设备在哪一个DRX组,以及在一个DRX组中的具体哪一个或者多个服务小区发送如上所述指示信息,可以由协议预先定义好,或者通过网络设备发送配置信令或指示信令进行指示。
可选的,本申请实施例涉及的各指示信息,可以包含终端设备开始或延长或结束第二服务小区的DRX激活时间的起始时刻。
示例性的,如上各指示信息包含drx-InactivityTimer-2启动/重启/停止的时刻,该时刻可以是具体的符号、或时隙、或子帧等。
可选的,终端设备开始或延长或结束第二服务小区的DRX激活时间的起始时刻也可以由协议预先定义好。
例如,终端设备在接收到第一/第二指示信息之后的第一个OFDM符号、或下一个时隙的起始时刻(或起始OFDM符号)、或第一/第二指示信息所在时隙的起始时刻(或起始OFDM符号)、或第一/第二指示信息所在时隙的结束时刻(或结束OFDM符号)、或接收到第一/第二指示信息之后间隔一段时间之后启动或重启drx-InactivityTimer-2定时器。终端设备在接收到第三指示信息之后的第一个OFDM符号、或下一个时隙的起始时刻(或起始OFDM符号)、或第三指示信息所在时隙的起始时刻(或起始OFDM符号)、或第三指示信息所在时隙的结束时刻(或结束OFDM符号)、或接收到第三指示信息之后间隔一段时间之后停止drx-InactivityTimer-2定时器。
可选的,本申请实施例涉及的各个指示信息可以承载PDCCH(如DCI)中,或承载在PDSCH中(如MAC CE信令),这里不做限定。
当指示信息承载在DCI中时,承载指示信息的DCI可以是调度DCI,也可以是非调度DCI,这里不做限定。
可选的,本申请实施例涉及的各指示信息,可以包括一个或多个信息比特,该信息比特可以是现有DCI格式(DCI format)中的预留比特,或者在现有DCI格式上新增的比特,或者是重解释现有DCI格式中的一个或多个信息域,这里不做限定。
可选的,承载指示信息的DCI的循环冗余校验(Cyclic Redundancy Check,CRC) 可以由多种无线网络临时标识(Radio Network Temporary Identifier,RNTI)加扰,例如可以包括如下几种RNTI中的一种或多种:小区无线网络临时标识(cell RNTI,C-RNTI),调制编码方案无线网络临时标识(modulation and coding scheme-RNTI,MCS-RNTI),配置的调度无线网络临时标识(Configured Scheduling RNTI,CS-RNTI),时隙格式指示无线网络临时标识(Slot Format Indication RNTI,SFI-RNTI)。
可选的,本申请实施例涉及的各指示信息,可以由网络配置,也可以由协议规定,这里不做限定。
以下介绍通过DCI承载如上各指示信息的可能的具体实施方式。
实施方式1:
实施方式1针对如上所述的方式1中的第一指示信息,即针对:第一指示信息指示终端设备在第二服务小区上从DRX非激活时间回到DRX激活时间。
网络设备在主服务小区(PCell)上可以发送针对辅服务小区的休眠指示(SCell dormancy indication),所述休眠指示用于指示终端设备在SCell上在休眠部分宽带(dormant bandwidth part,dormant BWP)和非休眠BWP(non-dormant BWP)之间进行切换。在DRX激活时间时,网络设备发送的DCI格式0_1和/或DCI格式1_1可以包括所述休眠指示。其中,调度DCI和非调度DCI都可以承载所述休眠指示。例如,调度DCI承载休眠指示时,DCI格式0_1和/或DCI格式1_1可以调度数据(如物理上行共享信道(physical uplink shared channel,PUSCH)或PDSCH),并同时承载休眠指示。当非调度DCI承载休眠指示时,DCI格式1_1用于承载休眠指示,且DCI格式1_1不用于调度PDSCH,DCI格式0_1不用于承载休眠指示。同时调度数据并承载休眠指示的PDCCH称为Case 1 PDCCH,承载休眠指示但不调度数据的PDCCH称为Case 2 PDCCH。
调度DCI是否承载休眠指示可以由网络设备进行配置。如果网络设备配置一个或多个辅小区组,则调度DCI承载休眠指示,休眠指示由一个调度DCI中的一个比特位图表示,所述比特位图的比特个数等于所配置的辅小区组的个数,且比特位图的每一个比特与所配置的辅小区组一一对应。如果一个比特置0,表示对应的辅小区组中的辅小区停留在休眠BWP或切换到休眠BWP,如果一个比特置1,表示对应的辅小区组中的辅小区停留在当前非休眠BWP或从休眠BWP切换到一个非休眠BWP。
如果终端设备检测到DCI格式1_1,且该DCI的CRC由C-RNTI或MCS-RNTI加扰,且该DCI中的频域资源分配域(frequency domain resource assignment field,FDRA field)置成全0(针对资源分配类型0的资源分配方式或动态切换的资源分配方式)或全1(针对资源分配类型1的资源分配方式或动态切换的资源分配方式),则该DCI是承载休眠指示的非调度DCI。该DCI包括一个比特位图,该比特位图中的比特按照一定的顺序与所配置的辅小区一一对应。如果一个比特置0,表示对应的辅小区停留在休眠BWP或切换到休眠BWP,如果一个比特置1,表示对应的辅小区停留在当前非休眠BWP或从休眠BWP切换到一个非休眠BWP。
在本方式中,第一服务小区为主服务小区(PCell),第一服务小区配置第一DRX,第二服务小区为辅服务小区,第二服务小区配置第二DRX,配置第二DRX的服务小区也可以包括除第二服务小区以外的其他辅服务小区。
应理解,当配置第二DRX的服务小区被配置到一个辅小区组中时,则网络设备可以 通过Case 1 PDCCH给该服务小区发送休眠指示。当所有配置第二DRX的服务小区都没有被配置到任意一个辅小区组中时,网络设备发送的Case 1 PDCCH的DCI中不包括针对配置第二DRX的服务小区的休眠指示。而Case 2 PDCCH中包括针对配置第二DRX的服务小区的休眠指示。
当第一DRX组在DRX激活时间,第二DRX组在DRX非激活时间时,Case 1和/或Case 2 PDCCH的DCI中对应第二DRX组的服务小区的休眠指示信息域中的一个或多个信息比特用于承载第一指示信息。所述一个或多个信息比特设置成第一状态时,用于指示第二DRX组的drx-InactivityTimer-2启动,所述一个或多个信息比特设置成第二状态时,用于指示第二DRX组的drx-InactivityTimer-2不启动。
如果所述一个或多个信息比特设置成第一状态,指示第二DRX组的drx-InactivityTimer-2启动。则,所述一个或多个信息比特对应的辅服务小区如果当前位于休眠BWP,则从休眠BWP切换到一个非休眠BWP,例如切换到网络设备通过配置信息指定的一个非休眠BWP;如果当前位于非休眠BWP,则继续停留在当前非休眠BWP或者切换到另一个非休眠BWP,例如切换到网络设备通过配置信息指定的一个非休眠BWP。可选的,Case 1和/或Case 2 PDCCH的DCI中除所述一个或多个信息比特以外的其他的对应第二DRX组的服务小区的休眠指示信息比特,可以仍然按照如上所述规则指示对应的辅小区的休眠行为,即是否在休眠BWP和非休眠BWP之间进行切换。
应理解,Case 1和/或Case 2 PDCCH的DCI中对应第一DRX组的服务小区的休眠指示信息域仍然用于指示对应辅小区的休眠行为。
如果所述一个或多个信息比特设置成第二状态,指示第二DRX组的drx-InactivityTimer-2不启动。则第二DRX组的服务小区可以停留在当前BWP,或者切换到休眠BWP(如果当前即休眠BWP则继续停留在休眠BWP)。
当第一DRX组在DRX激活时间,且,第二DRX组也在DRX激活时间时,Case 1和/或Case 2 PDCCH的DCI中对应第二DRX组的服务小区的休眠指示信息域仍然用于指示对应辅小区的休眠行为,即是否在休眠BWP和非休眠BWP之间进行切换。
针对如上Case 1和/或Case 2 PDCCH中用于表示第一指示信息的一个或多个信息比特具体是哪些信息比特,可以通过网络设备进行配置或指示,或通过协议预先定义好,例如协议预先定义一定的规则来确定所述一个或多个信息比特。
示例性的,针对Case 1 PDCCH,如果第二DRX组中的服务小区只配置一个辅小区组,则使用该辅小区组对应的那一个DCI中的休眠指示信息比特来承载第一指示信息。如果第二DRX组中的服务小区配置多个辅小区组,则在第二DRX组中的服务小区配置的多个辅小区组中将辅小区组编号最大或最小的那个辅小区组所对应的那一个休眠指示信息比特用来承载第一指示信息。针对Case 2 PDCCH,在Case 2 PDCCH的DCI中对应第二DRX组的服务小区的休眠指示信息域中,将对应的第二DRX组的服务小区中的按照服务小区编号最大或最小的服务小区对应的那一个休眠指示信息比特用来承载第一指示信息。
该实施方式中,可以由网络设备进行配置或指示,或由协议预先规定具体哪种PDCCH承载第一指示信息。例如只有Case 1 PDCCH承载第一指示信息,或只有Case 2 PDCCH承载第一指示信息,或Case 1和Case 2 PDCCH都承载第一指示信息。
实施方式2:
该实施方式中,主服务小区PCell配置第一DRX,网络设备如果配置第二DRX,则配置第二DRX的服务小区不配置休眠指示功能或不激活休眠指示功能。例如,配置第二DRX的服务小区不配置到任意一个辅小区组中。另外,网络设备配置或协议规定,Case 2 PDCCH的DCI中不包括针对第二DRX组中的服务小区的休眠指示比特。也就是说,配置第二DRX的服务小区不配置休眠BWP。本申请不限制配置第一DRX的服务小区是否配置休眠指示功能。
具体第一/第二/第三指示信息如何实现,可以参考如上描述,此处不再赘述。
本申请实施例中的各实施方式可以相互结合以实现不同的技术效果。
通过上述可知,本申请实施例中的网络设备可以基于一个DRX来指示另一个DRX的DRX状态(即跨DRX组或者跨载波指示),可以更灵活地控制终端设备在不同的DRX(或者说不同的子载波上)的DRX状态。可以在有数据到来时使其他DRX回到DRX激活时间监听PDCCH,从而提高终端设备吞吐量,降低数据时延;也可以在没有数据时使其他DRX维持或回到DRX非激活时间,这样终端设备就可以关闭其他DRX对应的射频链路,从而可以节省功耗。
