在第一种可能的实现方案中,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期不变,可以减少在其他载波上执行PDCCH监测的时长,进而减少了终端设备的功耗。
结合第一方面,在第二种可能的实现方案中,在第一条件为终端设备监测到在第一载波上的第一定时器超时的情况下,第一DRX周期的长度比第二DRX周期的长度长;第一定时器超时是指终端设备在第一定时器对应的时间段中的每个第一DRX周期内均接收到控制信息。
可选的,在终端设备满足第二条件的情况下,终端设备启动或者重启该第一定时器。其中,第二条 件可以为该终端设备在该第一载波的该第一DRX周期内没有接收到控制信息;或者,第二条件可以为该终端设备在该第一载波的第二定时器超时,该第二定时器超时是指该终端设备在该第二定时器对应的时间段内未接收到控制信息。可选的,在第一定时器启动或重启之前,终端设备在第一载波使用的DRX周期可以为第一DRX周期或第二DRX周期。
其中,第二定时器的时间段可以为i个第二DRX周期的时长,i为正整数。例如,可以设定第二定时器的取值为2,表示第二定时器对应的时间段内包含2个第二DRX周期。第一定时器的时间段可以为j个第一DRX周期的时长,j为正整数。例如,可以设定第一定时器的取值为1,表示第一定时器对应的时间段内包含1个第一DRX周期。例如,第一定时器为:drx-long cycle timer。
可选的,多个载波中的不同载波对应的第一定时器的值不完全相同。换句话说,多个载波中不同载波对应的第一定时器的值可以各不相同;或者,多个载波中部分对应的第一定时器的值可以相同、部分载波对应的第一定时器的值不同。如果将多个载波划分为主载波和辅载波,则可以为主载波和辅载波分别配置不同的第一定时器的值,所述主载波对应的第一定时器的值小于或等于所述辅载波对应的第一定时器的值。
在第二种可能实现方案中,第一DRX周期的长度比第二DRX周期的长度长,这样在相同的时间段中,采用第一DRX周期执行PDCCH监测的时长比采用第二DRX周期执行PDCCH监测的时长要长,因此,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期保持不变,可以减少其他载波执行PDCCH监测的时长。另外,由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例将辅载波对应的第一定时器配置较大值,可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合第一方面,在第三种可能的实现方案中,在该第一条件为终端设备监测到在第一载波上的第一定时器超时的情况下,第二DRX周期的长度比第一DRX周期的长度长;第一定时器超时是指终端设备在第一定时器对应的时间段内未接收到控制信息。
可选的,在所述终端设备满足第三条件的情况下,所述终端设备启动或者重启所述第一定时器;所述第三条件可以为所述终端设备在所述第一载波的所述第一DRX周期内接收到控制信息;或者,所述第三条件可以为所述终端设备监测到在所述第一载波的第一DRX周期内第三定时器超时,所述第三定时器超时是指所述终端设备在所述第三定时器对应的时间段内未接收到控制信息;或者,所述第三条件可以为所述终端设备监测到在所述第一载波的第四定时器超时;所述第四定时器超时是指所述终端设备在所述第四定时器对应的时间段的每个第二DRX周期内均接收到控制信息。
其中,终端设备在第一载波上的第一定时器的时间段内采用第一DRX周期进行非连续接收。可选的,在第一定时器启动或重启之前,终端设备在第一载波使用的DRX周期可以为第一DRX周期或第二DRX周期。
可选的,多个载波中的不同载波对应的第一定时器的值不完全相同。如果将多个载波划分为主载波和辅载波,则可以为主载波和辅载波分别配置不同的第一定时器的值,所述主载波对应的第一定时器的值大于或等于所述辅载波对应的第一定时器的值。
在第三种可能实现方案中,由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例将主载波对应的第一定时器配置较大值,在终端设备需要长度短的DRX周期变更为长度长的DRX周期的情况下,辅载波上的DRX周期保持不变,可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合第一方面,在可能的实现方案中,第一方面中所涉及的第一定时器的值是由无线资源控制RRC信令配置的。具体是接入网设备通过RRC信令将第一定时器的值或者取值集合发送给终端设备。
结合第一方面,在第四种可能的实现方案中,在该第一条件为该终端设备在第一时间段内接收到的控制信息的数量大于预设值的情况下,该第一DRX周期的长度比该第二DRX周期的长度长;该第一时间段为第一DRX周期对应的时长,该预设值为k,k为正整数。
可选的,第一时间段可以为p个第一DRX周期或者q个第二DRX周期,p、q为正整数,本申请实施例对此不做限定。
可选的,多个载波中的不同载波对应的预设值不完全相同;多个载波包括主载波和辅载波;主载波对应的预设值小于或者等于辅载波对应的预设值。
可选的,预设值是由无线资源控制RRC信令配置的。具体是接入网设备通过RRC信令将预设值发送给终端设备。
在第四种可能实现方案中,第一DRX周期的长度比第二DRX周期的长度长,这样在相同的时间段中,采用第一DRX周期执行PDCCH监测的时长比采用第二DRX周期执行PDCCH监测的时长要长,因此,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期保持不变,可以减少其他载波执行PDCCH监测的时长。另外由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例配置的辅载波对应的预设值较大,这样终端设备在辅载波上接收到较多的控制信息的情况下,才能将辅载波上的长度长的DRX周期变更为长度短的DRX周期,这样可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合第一方面,在一种可能的实现方案中,第一DRX周期和第二DRX周期均包括持续时间(on-duration)。不同载波对应的on-duration长度不同。该多个载波包括主载波和辅载波;在相同的DRX周期中主载波对应的on-duration长度大于辅载波对应的on-duration长度。
可选的,该终端设备应用于NR通信系统。
第二方面,本申请实施例提供了一种无线通信方法,终端设备可以在多个载波上进行非连续接收,该方法包括:终端设备在第一载波的第一时间段内监测物理下行控制信道PDCCH,第一载波为多个载波中的任意一个载波;终端设备在第一载波的第一时间段内接收到控制信息的情况下,在第二时间段内终端设备只在该第一载波监测PDCCH。
在第二方面中,这样可以减少没有接收到控制信息的载波对PDCCH的监测,降低了终端设备的功耗。
结合第一方面,在一种可能的实现方案中,在第二时间段内终端设备在除第一载波外的其他载波不监测PDCCH。其中,第二时间段与第一时间段的时间不重叠。
结合第一方面,在一种可能的实现方案中,该方法还包括:终端设备在第一载波的第一时间段内接收到控制信息的情况下,终端设备在第一载波上启动或者重启第一定时器,且在除第一载波外的其他载波上不启动或者重启第一定时器。其中,第一定时器用于监测PDCCH。当所述第一定时器启动或重启时,所述终端设备开始监测PDCCH。这样在所述第一定时器启动或重启之后所述终端设备在第二时间段内只在所述第一载波监测所述PDCCH,在除第一载波外的其他载波不监测所述PDCCH。
由此可见,在这种可能的实现方案中,在第一载波上接收到控制信息的情况下,终端设备在第二时间段内仅在第一载波上执行PDCCH监测,且在所述第二时间段内所述终端设备在除第一载波外的其他载波不监测所述PDCCH。这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
结合第一方面,在一种可能的实现方案中,该方法还包括:终端设备在第一载波的第一时间段内接收到控制信息的情况下,终端设备在多个载波上启动或者重启第一定时器,在所述第一定时器启动或重启之后所述终端设备在第二时间段内只在所述第一载波监测所述PDCCH,在第二时间段内除第一载波外的其他载波不监测所述PDCCH。
其中,所述第一定时器的启动时刻不晚于所述第二时间段的开始时刻;所述第一定时器的结束时刻与所述第二时间段的结束时刻相同。
在这种可能的实现方案中,在第一载波上接收到控制信息的情况下,终端设备在第二时间段内仅在第一载波上执行PDCCH监测,且在所述第二时间段内所述终端设备在除第一载波外的其他载波不监测所述PDCCH。这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
可选的,该终端设备应用于NR通信系统。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例进行说明。
请参见图1,图1是本申请实施例涉及的一种可能的通信系统的架构示意图。下面先对图1中的各个网元进行介绍:
接入网(radio access network,RAN)设备:主要负责空口侧的无线资源管理、服务质量(quality of service,QoS)管理、数据压缩和加密等功能。所述接入网设备可以包括各种形式的基站,例如:宏基站,微基站(也称为小站),中继站,接入点等。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,在第五代(5th generation,5G)系统中,称为gNB;在LTE系统中,称为演进的节点B(evolved NodeB,eNB或者eNodeB)等。
终端设备:可以为终端设备(user equipment,UE)、手持终端、笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant,PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、机器类型通信(machine type communication,MTC)终端或是其他可以接入网络的设备。
终端设备与接入网设备之间采用某种空口技术相互通信。可选地,该空口技术是基于LTE标准的空口技术;或者,该空口技术是基于5G标准的空口技术,比如该无线空口是NR(New Radio);或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可以理解的是,在图1所示的通信系统中,各网元的功能以及接口仅为示例性的,各个网元在应用于本申请的实施例中时,并非全部功能都是必需的。
本申请各个实施例提供的无线通信方法可以基于图1所示的通信系统的架构。本申请实施例中的终端设备被配置了DRX功能,DRX功能通过控制终端设备在一些时间段内不监测PDCCH来降低终端设备的功耗,5GNR沿用了LTE的DRX机制。
请参见图2,为本申请实施例提供了一种DRX周期的示例图。如图2所示,一个完整的DRX周期200(DRX cycle)由DRX持续时间201(drx-on duration)和DRX休眠期202(opportunity for DRX)构成。
终端设备在RRC连接态(RRC_CONNECTED)可以被配置进行非连续接收(DRX)。DRX可以控制终端设备监测PDCCH的行为。具体地,DRX可以控制终端设备监测小区无线网络临时标识(cell RNTI,C-RNTI)、配置调度RNTI(configured scheduling RNTI,CS-RNTI)、中断RNTI(interruption RNTI,INT-RNTI)、 时隙格式指示RNTI(slot format indication RNTI,SFI-RNTI)、半持久性CSI RNTI(semi-persistent CSI RNTI,SP-CSI-RNTI)、发射功率控制PUCCH-RNT(transmit power control-PUCCH-RNTI,TPC-PUCCH-RNTI)、发射功率控制PUSCH-RNTI(transmit power control-PUSCH-RNTI,TPC-PUSCH-RNTI)、发射功率控制探测参考信号RNTI(transmit power control-sounding reference signal-RNTI,TPC-SRS-RNTI)等标识加扰的PDCCH。无线网络临时标识(radio network temporary identity,RNTI)加扰PDCCH也可以理解为RNTI加扰DCI(PDCCH可以承载DCI)。
NR中,RRC通过以下一个或多个参数控制DRX操作。
下列参数可用于定义DRX周期内终端设备的行为:
-DRX持续时间(drx-on duration):在一个DRX cycle开始的一段持续时间;终端设备在这一段持续时间内监测PDCCH。如果终端设备监测到承载于PDCCH的控制信息,则终端设备启动DRX待用定时器。
-DRX持续时间定时器(drx-on duration timer):on duration是周期性重复的,DRX cycle是on duration重复的周期。drx-on duration timer在on duration的起始时刻启动,drx-on duration timer的时长为on duration时长。
-DRX待用定时器(drx-Inactivity Timer):终端设备从PDCCH监测到控制信息开始的一段持续时间。当终端设备在该时段期间未监测到承载于PDCCH的控制信息时,则DRX待用定时器超时,终端设备重新进入DRX周期。当终端设备在该时段期间监测到承载于PDCCH的控制信息时,重启DRX待用定时器。
-DRX休眠期(opportunity for DRX):终端设备在这一时间段不监测PDCCH。
-DRX长周期(drx-long cycle):长的DRX cycle;(在LTE中,名称为long DRX-cycle)。
-DRX短周期(drx-short cycle):短的DRX cycle;(在LTE中,名称为short DRX-cycle)。
-DRX短周期定时器(drx-short cycle timer):终端设备用短DRX cycle的持续时间,该参数是可选的。
-drx-retransmission timer DL(per DL HARQ process):直到收到一个下行重传的最大持续时间;(在LTE中,该timer的名称为drx-Retransmission Timer)。
-drx-retransmission timer UL(per UL HARQ process):直到收到一个上行重传授权(grant)的最大持续时间(the maximum duration until a grant for UL retransmission is received);(在LTE中,该timer的名称为drx-UL Retransmission Timer)。
当DRX cycle被配置时,激活期(Active time)包括以下至少一项:
1)drx-on Duration Timer or drx-Inactivity Timer or drx-Retransmission Timer or drx-UL Retransmission Timer or ra-Contention Resolution Timer正在运行;
2)调度请求(scheduling request,SR)被发送并且处于挂起(pending);
3)在成功接收一个随机接入响应(random access response,RAR)后还没有接收到一个指示新传的C-RNTI加扰的PDCCH,其中,所述RAR不是终端设备从基于竞争的随机接入前导选择的随机接入前导的RAR。
当终端设备处于Active Time时,终端设备需要监测PDCCH;否则,终端设备不需要监测PDCCH。
采用DRX功能会涉及降低功耗和用户等待时间之间的权衡。为了满足要求,可以为每一个终端设备配置两个长度不同的DRX周期,包括短周期和长周期。例如,在web浏览服务中,在用户阅读下载的web页面时,终端设备连续监测PDCCH通常是浪费资源这一情形下,采用长DRX周期是有利于降低功耗的。又如,当用户请求另一web页面时,需要重新开始数据传输时,这一情形下采用短DRX周期能较快反应,减少用户的等待时间。
实际应用中,终端设备可以被配置于载波聚合(carrier aggregation,CA)的场景中,载波聚合具体是指两个或更多的成员载波(component carriers,CC)被聚合。终端设备根据其能力可以在一个或多个载波上同时接收或发送。现有方案中的多个载波使用相同的DRX参数,且会同步监测PDCCH或同步通过启动或重启定时器监测PDCCH等,然而这样会导致有些负载较少的载波与负载较多的载波采用相同的频率对PDCCH进行监测,造成了终端设备功耗浪费。
例如,终端设备的服务小区包括主小区和辅小区,在RRC连接建立/重建/切换过程中,主小区可以提供移动性信息,在RRC连接重建/切换过程中,主小区可以提供安全输入。实际调度中,往往在主小区和辅小区上的调度的特征不一样。比如,在主小区上调度较多、较频繁,表示主小区的负载较多,在激活的辅小区上调度较少、较稀疏,表示辅小区的负载较少。由于主小区和激活的辅小区进行PDCCH监测的时间一致,虽然终端设备在辅小区监测PDCCH,但很少会收到控制信息,从而造成终端设备的功 耗浪费。
在本申请的实施例中,终端设备可以实现在不同载波上对PDCCH执行监测的时间不一致,以使负载较少的载波与负载较多的载波不需要一直同时监测PDCCH,进而减少了终端设备的功耗浪费。具体可以参见以下实施例中的具体介绍。
需要说明的是,根据终端设备的能力,终端设备可以被配置辅小区,被配置的辅小区和主小区一起形成终端设备的一个服务小区集合。通过RRC信令可以重配、添加和移除辅小区。与主小区相应的载波是主载波PCC(Primary component carrier),与辅小区相应的载波是辅载波SCC(Secondary component carrier)。本申请实施例中所涉及的多个载波、主载波、辅载波为终端设备中已经激活的载波。
又一需要说明的是,本申请各实施例中的各种timer的名称、各种载波的名称只是示例性的,实际应用中可以使用不同的名称,本申请对此不做限定。本申请实施例中涉及的“接收到控制信息”具体是指成功接收到承载于PDCCH的控制信息或者指成功解码承载于PDCCH的数据包,或者用“接收到PDCCH”来描述
本申请实施例还可应用于其它需要在多个载波上以DRX周期监测PDCCH的通信系统中。术语“系统”可以和“网络”相互替换。本申请实施例描述的系统架构是为了便于说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变,本申请实施例提供的技术方案对于类似的技术问题,同样适用。在本申请的描述中,“多个”是指两个或多于两个,“至少两个”是指两个或多于两个。
请参见图3,为本申请实施例提供了一种无线通信方法的流程示意图。
301,终端设备在第一载波上按照所述第一DRX周期进行非连续接收。其中,所述第一载波为多个载波中的任意一个载波。
302,若第一载波满足第一条件,所述终端设备在第一载波的下一个DRX周期由所述第一DRX周期变成所述第二DRX周期,在其他载波的DRX周期不变。
在本申请实施例中,无线通信方法应用于包含接入网设备和终端设备的无线通信系统,所述接入网设备为所述终端设备配置至少两个非连续接收DRX周期,所述至少两个DRX周期包括第一DRX周期和第二DRX周期。
其中,所述第一DRX周期和所述DRX第二周期的周期长度不同。第一DRX周期与第二周期DXR为至少两个DRX周期中的任意两个长度不同的DRX周期,本申请实施例以第一DRX周期和第二DRX周期为例进行说明,
在载波聚合的场景中,终端设备可以在多个载波接收和发送数据。该终端设备可以在多个载波上按照DRX周期进行非连续接收,以实现对PDCCH的监测。可选的方式中,多个载波在同一时间段内所采用的DRX周期可以全部相同、也可以部分相同,例如,终端设备在第一载波以第一DRX周期进行非连续接收,多个载波中除第一载波之外的其他载波以第一DRX周期或以第二DRX周期进行非连续接收,以监测是否接收到控制信息,该控制信息承载于PDCCH。
可选的,在多个载波中一个载波对应一个第一定时器。各个载波的第一定时器可以不同时启动或者重启。
以下针对不同的情况对图3所示的不同实现方案进行详细介绍。
1、在一种可能的实现方案中,第一条件可以为终端设备在所述第一载波接收到控制信息;或者,第一条件可以为终端设备监测到在所述第一载波上的第一定时器超时。这一情况下,所述第一DRX周期的长度比所述第二DRX周期的长度长;所述第一定时器超时是指终端设备在启动或者重启的所述第一定时器的时间段内未接收到控制信息。
如果终端设备在第一载波的第一DRX周期的持续时间(on-duration)内接收到控制信息,则终端设备在第一载波的下一个DRX周期由第一DRX周期变成第二DRX周期,在其他载波的DRX周期不变。
如果终端设备在第一载波上监测到第一定时器超时,则终端设备将第一载波的下一个DRX周期由第一DRX周期变成第二DRX周期,在其他载波的DRX周期不变。
可选的,第一定时器可以在满足以下条件的情况下启动或者重启:终端设备在第一载波的第一DRX周期的持续时间(on-duration)内接收到控制信息;或者,终端设备在第一载波的第一定时器的时间段内接收到控制信息。例如,第一定时器为drx-Inactivity Timer,该第一定时器的取值为大于等于0的整数。可选的,每个载波的drx-Inactivity Timer可以独立运行。
举例说明,请参见图4,为本申请实施例提供了一种变更DRX周期的示例图。其中,第一载波和第二载波均以第一DRX周期进行非连续接收,其中第一载波为多个载波中满足第一条件的载波,第二载波为除第一载波之外的其他载波中的任意一个。
如图4所示,对于第一载波而言,终端设备在第一载波的on-duration内的T41时刻接收到了控制信息,则终端设备在第一载波的下一个DRX周期变为第二DRX周期。以及由于在T41时刻接收到了控制信息,终端设备在T41时刻启动第一定时器,并在第一定时器的时间段内对PDCCH进行监测;接着在T42时刻接收到了控制信息,终端设备在T42时刻重启第一定时器,并在第一定时器的时间段内对PDCCH进行监测;由于在T42时刻重启的第一定时器的时间段内未接收到控制信息,表示第一定时器超时,因此终端设备在第一载波的下一个DRX周期变为第二DRX周期。由图4可以看出在T42时刻重启的第一定时器的时间段内未接收到控制信息,因此在第一DRX周期内在T42时刻重启的第一定时器的结束时刻停止对PDCCH进行监测。
而对于第二载波而言,由于终端设备在第二载波on-duration内未接收到控制信息,第二载波未启动定时器,且继续以第一DRX周期进行非连续接收,以保持在第二载波上的DRX周期不变,这样可以减少在第二载波上对PDCCH的监测。
在1中介绍的可能实现方案中,第一DRX周期的长度比第二DRX周期的长度长,这样在相同的时间段中,采用第一DRX周期执行PDCCH监测的时长比采用第二DRX周期执行PDCCH监测的时长要长,因此,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期不变,可以减少在其他载波上执行PDCCH监测的时长,进而减少了终端设备的功耗。
结合以上图3的无线通信方法1中介绍的方案,本申请实施例中当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,终端设备在某个载波的drx-Inactivity Timer超时或者终端设备在某个载波的on duration期间收到控制信息时,则该载波启动或者重启drx-Short Cycle Timer,下一个cycle变为drx-Short Cycle。而终端设备在其他载波不会因此而启动或者重启drx-Short Cycle Timer,并且下一个cycle并不会因此而发生改变,依然保持原cycle类型不变。而现有的方案中,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,如果某个载波中的drx-Inactivity Timer超时时,终端设备在所有载波都启动或者重启drx-Short Cycle Timer,下一个cycle变为drx-Short Cycle。这样终端设备只在drx-Inactivity Timer超时或者on duration期间收到控制信息的载波上启动或者重启drx-Short Cycle Timer,并把下一个cycle变为drx-Short Cycle,而其他载波的cycle并不会因此而发生改变,从而减少drx-Short Cycle的配置,达到减少对PDCCH监测的目的。
2、在一种可能的实现方案中,第一条件为所述终端设备监测到在所述第一载波上的第一定时器超时。这一情况下,所述第一DRX周期的长度比所述第二DRX周期的长度长;所述第一定时器超时是指所述终端设备在所述第一定时器对应的时间段中的每个第一DRX周期内均接收到控制信息。
如果终端设备在第一载波上的第一定时器对应的时间段中的每个第一DRX周期内均接收到控制信息,则终端设备将第一载波的下一个DRX周期由第一DRX周期变成第二DRX周期,在其他载波的DRX周期不变。
可选的,在所述终端设备满足第二条件的情况下,所述终端设备启动或者重启所述第一定时器;所述第二条件可以为所述终端设备在所述第一载波的所述第一DRX周期内没有接收到控制信息;或者,第二条件可以为所述终端设备在所述第一载波的第二定时器超时,所述第二定时器超时是指所述终端设备在所述第二定时器对应的时间段内未接收到控制信息。
其中,终端设备在第一载波上的第一定时器的时间段内采用第一DRX周期进行非连续接收。可选的,在第一定时器启动或重启之前,终端设备在第一载波使用的DRX周期可以为第一DRX周期或第二DRX周期。
举例说明,请参见图5a,为本申请实施例提供了一种变更DRX周期的示例图。其中第一载波501是在第二条件为在所述第一载波501的所述第一DRX周期内没有接收到控制信息的情况下启动或重启的第一定时器。第一载波502是在第二条件为在第一载波502的第二定时器超时的情况下启动的第一定时器。具体介绍如下:
对于第一载波501而言,终端设备在第一载波501的第一DRX周期内未接收到控制信息;接着在第一DRX周期的结束时刻T51启动第一定时器,并在第一定时器中on-duration内的T52时刻接收到控制信息,则终端设备在第一载波的下一个DRX周期变为第二DRX周期,对于多个载波中除第一载波501之外的其他载波保持DRX不变。
可选的,在第一载波501的T52时刻接收到控制信息接收到控制信息的情况下,终端设备可以启动定时器56,例如该定时器56为drx-Inactivity Timer,并在定时器56的时间段内对PDCCH进行监测,由图可以看出在定时器56的时间段内未接收到控制信息,表示定时器56超时,因此在定时器56的结束时刻停止对PDCCH进行监测。
对于第一载波502而言,终端设备在第一载波502的第二定时器超时;接着在第二定时器的结束时刻T53启动第一定时器,并在第一定时器中on-duration内的T54时刻接收到控制信息,则终端设备在第一载波的下一个DRX周期变为第二DRX周期,对于多个载波中除第一载波502之外的其他载波保持DRX不变。
可选的,在第一载波502的T54时刻接收到控制信息的情况下,终端设备可以启动定时器56,例如该定时器56为drx-Inactivity Timer,并在定时器56的时间段内对PDCCH进行监测;接着在T55时刻接收到了控制信息,终端设备在T55时刻重启定时器56,并在定时器56的时间段内对PDCCH进行监测;由于在T55时刻重启的定时器56的时间段内未接收到控制信息,因此在第一DRX周期内在T55时刻重启的定时器56的结束时刻停止对PDCCH进行监测。本申请实施例中对定时器56的时长或者取值不做限定。
在2中介绍的可能实现方案中,第二定时器的时间段可以为i个第二DRX周期的时长,i为正整数。例如,可以设定第二定时器的取值为2,表示第二定时器对应的时间段内包含2个第二DRX周期。例如,第二定时器为:drx-short cycle timer。
在2中介绍的可能实现方案中,第一定时器的时间段可以为j个第一DRX周期的时长,j为正整数。例如,可以设定第一定时器的取值为1,表示第一定时器对应的时间段内包含1个第一DRX周期。例如,第一定时器为:drx-long cycle timer。
可选的,多个载波中的不同载波对应的第一定时器的值不完全相同。换句话说,多个载波中不同载波对应的第一定时器的值可以各不相同;或者,多个载波中部分对应的第一定时器的值可以相同、部分载波对应的第一定时器的值不同。具体实现中,多个载波的每一个载波上都有与其对应的第一定时器,例如,如图5a所示,存在与第一载波501对应的第一定时器和与第一载波502对应的第一定时器。同理可选的,对于第二定时器和图5a中定时器56而言,多个载波中的不同载波对应的第二定时器的值不完全相同;多个载波中的不同载波对应的定时器56的值不完全相同。
举例来说,如果将多个载波划分为主载波和辅载波,则可以为主载波和辅载波分别配置不同的第一定时器的值,所述主载波对应的第一定时器的值小于或等于所述辅载波对应的第一定时器的值。例如,为主载波配置第一定时器取值集合{1、2、3};为辅载波配置第二定时器取值集合{3、4、5}。又如,为主载波和辅载波配置相同的第一定时器取值集合{1、2、3、4、5、6},是实际应用时满足主载波的对应的第一定时器的值小于或等于所述辅载波对应的第一定时器的值即可。
举例来说,请参见图5b,为本申请实施例提供了一种变更DRX周期的示例图。其中主载波的第一定时器的取值为1,具体是指主载波的第一定时器的时间段内包括1个第一DRX周期;辅载波的第一定时器的取值为2,具体是指辅载波的第一定时器的时间段内包括2个第一DRX周期。
如图5b所示,终端设备在主载波的第一定时器的T57时刻接收到控制信息,表示终端设备在主载波的第一定时器超时,这样终端设备在主载波的下一个DRX周期由第一DRX周期变更为第二DRX周期。终端设备在辅载波的第一定时器的T58时刻、T59时刻接收到控制信息,表示终端设备在辅载波的第一定时器超时,这样终端设备在辅载波的下一个DRX周期由第一DRX周期变更为第二DRX周期。其中,终端设备可以在T57时刻、T58时刻、T59时刻启动定时器56。可以看出,由于辅载波对应的第一定时器的取值较大,因此辅载波需要在较多数量的长的DRX周期内均接收到控制信息,才能实现在辅载波上将长的DRX周期变更为短的DRX周期,这样可以减少辅载波对PDCCH的监测时间,进而减少了终端设备的功耗。
可选的,所述第一定时器的值是由无线资源控制RRC信令配置的。具体是接入网设备通过RRC信令将第一定时器的值或者取值集合发送给终端设备。
在2中介绍的可能实现方案中,第一DRX周期的长度比第二DRX周期的长度长,这样在相同的时间段中,采用第一DRX周期执行PDCCH监测的时长比采用第二DRX周期执行PDCCH监测的时长要长,因此,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期保持不变,可以减少其他载波执行PDCCH监测的时长。另外,由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例将辅载波对应的第一定时器配置较大值,可以减少 辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合以上图3的无线通信方法2中介绍的方案,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,基站为Pcell和Scell配置两套不同的drx-long Cycle Timer,Pcell配置的drx-long Cycle Timer值小于等于Scell配置的drx-long Cycle Timer值。可选方案中,可以保持PCell目前的配置不变,为Scell配置一套drx-long Cycle Timer。
终端设备分别在Pcell和Scell的on duration进行PDCCH的监测,只有各自载波的drx-long Cycle Timer超时,则该载波启动或者重启drx-Short Cycle Timer,下一个cycle变为drx-Short Cycle。
所述drx-long Cycle Timer超时与每个载波配置的drx-long Cycle Timer值有关,假如设定drx-long Cycle Timer值为N,那么终端设备需要在该载波连续N个drx-Long Cycle内的on duration期间收到控制信息时,该drx-long Cycle Timer超时。
当存在下面的条件之一时,drx-long Cycle Timer启动:
1.终端设备在drx-Long Cycle期间未接收到控制信息;
2.配置的drx-Short Cycle Timer超时。
具体的,当终端设备启动drx-long Cycle Timer时,同时启动一个计数器,如果在N个连续的drx-Long Cycle中都接收到了PDCCH,那么drx-long Cycle Timer超时,计数器清零。如果在N个连续的drx-Long Cycle中,某个drx-Long Cycle中的没有收到控制信息,此时计数器重置,drx-long Cycle Timer停止。当终端设备在drx-Long Cycle中接收到控制信息,或者终端设备在drx-Long Cycle的drx-Inactivity Timer超时,启动或者重启drx-long Cycle Timer。
可选的,不同的Scell的drx-long Cycle Timer值可以相同也可以不同。
由此可见,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,现有的方案中如果在某个载波中的drx-Inactivity Timer超时,所有载波的下一个cycle变为drx-Short Cycle。本申请实施例的终端设备分别在Pcell和Scell的on duration进行PDCCH的监测,只有各自载波的drx-long Cycle Timer超时,下一个cycle变为drx-Short Cycle,且为Pcell和Scell配置两套不同的drx-long Cycle Timer,减少Scell中drx-Short Cycle的配置,从而达到减少对PDCCH的监测的目的。
3、在一种可能的实现方案中,第一条件为所述终端设备监测到在所述第一载波上的第一定时器超时。这一情况下,所述第二DRX周期的长度比所述第一DRX周期的长度长;所述第一定时器超时是指所述终端设备在所述第一定时器对应的时间段内未接收到控制信息。
如果终端设备在第一载波上的第一定时器对应的时间段内未接收到控制信息,表示在第一载波上的第一定时器超时,则终端设备将第一载波的下一个DRX周期由第一DRX周期变成第二DRX周期,在其他载波的DRX周期不变。
可选的,在所述终端设备满足第三条件的情况下,所述终端设备启动或者重启所述第一定时器;所述第三条件可以为所述终端设备在所述第一载波的所述第一DRX周期内接收到控制信息;或者,所述第三条件可以为所述终端设备监测到在所述第一载波的第一DRX周期内第三定时器超时,所述第三定时器超时是指所述终端设备在所述第三定时器对应的时间段内未接收到控制信息;或者,所述第三条件可以为所述终端设备监测到在所述第一载波的第四定时器超时;所述第四定时器超时是指所述终端设备在所述第四定时器对应的时间段的每个第二DRX周期内均接收到控制信息。
其中,终端设备在第一载波上的第一定时器的时间段内采用第一DRX周期进行非连续接收。可选的,在第一定时器启动或重启之前,终端设备在第一载波使用的DRX周期可以为第一DRX周期或第二DRX周期。
举例说明,请参见图6a,为本申请实施例提供了一种变更DRX周期的示例图。其中第一载波601可以是在第三条件为在所述第一载波601的所述第一DRX周期内接收到控制信息的情况下启动或重启的第一定时器;第一载波601也可以是在所述第一载波的第一DRX周期内第三定时器超时的情况下启动或重启的第一定时器。第一载波602是在第三条件为在第一载波602的第三定时器超时或第四定时器超时的情况下启动的第一定时器。第三定时器以图6a中的定时器64为例,具体介绍如下:
对于第一载波601而言,终端设备在第一DRX周期的T61时刻接收到控制信息,则终端设备可以在第一DRX周期的结束时刻T63启动或者重启第一定时器。终端设备在第一载波601的第一定时器的时间段内未接收到控制信息,表示在第一载波601上的第一定时器超时,则终端设备在第一载波601的下一个DRX周期变为第二DRX周期,对于多个载波中除第一载波601之外的其他载波保持DRX不变。
可选的,在第一DRX周期的T61时刻接收到控制信息的情况下,终端设备可以启动定时器66,例 如该定时器66为drx-Inactivity Timer,并在定时器66的时间段内对PDCCH进行监测;接着在T62时刻接收到了控制信息,终端设备在T62时刻重启定时器66,并在定时器66的时间段内对PDCCH进行监测;由于在T62时刻重启的定时器66的时间段内未接收到控制信息,表示定时器66(也为第三定时器)超时,则终端数设备在第一DRX周期内在T62时刻重启的定时器66的结束时刻停止对PDCCH进行监测,以及同样可以实现终端设备在第一DRX周期的结束时刻T63启动第一定时器。
对于第一载波602而言,以第四定时器的时间段内包含一个第一DRX周期为例进行说明,终端在这一个第一DRX周期内的T64时刻接收到控制信息,则终端设备可以在第四定时器的结束时刻T65启动第一定时器。终端设备在第一载波602的第一定时器的时间段内未接收到控制信息,表示在第一载波602上的第一定时器超时,则终端设备在第一载波602的下一个DRX周期变为第二DRX周期,对于多个载波中除第一载波602之外的其他载波保持DRX不变。
可选的,在第一DRX周期的T64时刻接收到控制信息的情况下,终端设备可以启动定时器66,例如该定时器66为drx-Inactivity Timer,并在定时器66的时间段内对PDCCH进行监测;由于在T64时刻重启的定时器66的时间段内未接收到控制信息,表示定时器66(也为第三定时器)超时,则终端数设备在第一DRX周期内在定时器66的结束时刻停止对PDCCH进行监测,以及同样可以实现终端设备在第一DRX周期的结束时刻T65启动第一定时器。
在3中介绍的可能实现方案中,第四定时器的时间段可以为m个第一DRX周期的时长,m为正整数。例如,可以设定第四定时器的取值为2,表示第四定时器对应的时间段内包含2个第一DRX周期。例如,第四定时器为:drx-long-cycle-timer。
在3中介绍的可能实现方案中,第一定时器的时间段可以为n个第二DRX周期的时长,n为正整数。例如,可以设定第一定时器的取值为2,表示第一定时器对应的时间段内包含2个第二DRX周期。例如,第一定时器为:drx-short cycle timer。
进一步的,多个载波中的不同载波对应的第一定时器的值不完全相同。同理可选的,对于第三定时器、第四定时器和图6a中定时器66而言,多个载波中的不同载波对应的第三定时器的值不完全相同;多个载波中的不同载波对应的第四定时器的值不完全相同;多个载波中的不同载波对应的定时器66的值不完全相同。
举例来说,如果将多个载波划分为主载波和辅载波,则可以为主载波和辅载波分别配置不同的第一定时器的值,所述主载波对应的第一定时器的值大于或等于所述辅载波对应的第一定时器的值。例如,为主载波配置第一定时器取值集合{3、4、5};为辅载波配置第二定时器取值集合{1、2、3}。又如,为主载波和辅载波配置相同的第一定时器取值集合{1、2、3、4、5、6},是实际应用时满足主载波的对应的第一定时器的值大于或等于所述辅载波对应的第一定时器的值即可。
举例来说,请参见图6b,为本申请实施例提供了一种变更DRX周期的示例图。其中主载波的第一定时器的取值为4,具体是指主载波的第一定时器的时间段内包括4个第一DRX周期;辅载波的第一定时器的取值为2,具体是指辅载波的第一定时器的时间段内包括2个第一DRX周期。
如图6b所示,终端设备在主载波的第一定时器内的每个第一DRX周期均未接收到控制信息,表示终端设备在主载波的第一定时器超时,这样终端设备在主载波的下一个DRX周期由第一DRX周期变更为第二DRX周期。终端设备在辅载波的第一定时器内的每个第一DRX周期均未接收到控制信息,表示终端设备在辅载波的第一定时器超时,这样终端设备在辅载波的下一个DRX周期由第一DRX周期变更为第二DRX周期。可以看出,由于辅载波对应的第一定时器的取值较小,因此在辅载波的较少数量的短的DRX周期内均未接收到控制信息,就可以实现在辅载波上将短的DRX周期变更为长的DRX周期了,这样可以减少辅载波对PDCCH的监测时间,进而减少了终端设备的功耗。
可选的,所述第一定时器的值是由无线资源控制RRC信令配置的。具体是接入网设备通过RRC信令将第一定时器的值或者取值集合发送给终端设备。
在3中介绍的可能实现方案中,由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例将主载波对应的第一定时器配置较大值,在终端设备需要长度短的DRX周期变更为长度长的DRX周期的情况下,辅载波上的DRX周期保持不变,可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合以上图3的无线通信方法3中介绍的方案,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,为Pcell和Scell配置两套不同的drx-Short Cycle Timer值,Pcell配置的drx-Short Cycle Timer值大于等于Scell配置的drx-Short Cycle Timer值。终端设备分别在Pcell和Scell的 on duration进行PDCCH的监测,只有各自载波的drx-Short Cycle Timer超时,该载波的下一个cycle变为drx-Long Cycle。
所述drx-Short Cycle Timer超时与每个载波配置的drx-Short Cycle Timer值有关,假如设定drx-Short Cycle Timer值为N,那么终端设备需要在该载波连续N个drx-Short Cycle内没有收到控制信息时,该drx-Short Cycle Timer超时。
当存在下面的条件之一时,drx-Short Cycle Timer启动或者重启:
1.终端设备在drx-Short Cycle期间接收到控制信息;
2.终端设备在drx-Short Cycle的drx-Inactivity Timer超时;
3.配置的drx-long Cycle Timer超时。
可选的,不同的Scell的drx-Short Cycle Timer值可以相同也可以不同。
由此可见,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,现有的方案中如果某个载波中的drx-Short Cycle Timer超时时,所有载波的下一个cycle都从drx-Short Cycle变为drx-Long Cycle,且Pcell和Scell共用一套drx-Short Cycle Timer值。本申请实施例为Pcell和Scell配置两套不同的drx-Short Cycle Timer值,减少Scell中drx-Short Cycle的配置,从而达到减少对PDCCH的监测的目的。
4、在一种可能的实现方案中,第一条件为所述终端设备在第一时间段内接收到的控制信息的数量大于预设值。这一情况下,所述第一DRX周期的长度比所述第二DRX周期的长度长;所述第一时间段为第一DRX周期对应的时长,所述预设值为k,k为正整数。
如果终端设备在所述第一载波的第一时间段内接收到的控制信息的数量大于或等于预设值,则终端设备将第一载波的下一个DRX周期由第一DRX周期变成第二DRX周期,在其他载波的DRX周期不变。
可选的,第一时间段可以为p个第一DRX周期或者q个第二DRX周期,p、q为正整数,本申请实施例对此不做限定。
进一步的,多个载波中的不同载波对应的预设值不完全相同。换句话说,多个载波中不同载波对应的预设值可以各不相同;或者,多个载波中部分对应的预设值可以相同、部分载波对应的预设值不同。具体实现中,多个载波的每一个载波上都有与其对应的预设值。
举例来说,如果将多个载波划分为主载波和辅载波,则可以为主载波和辅载波分别配置不同的预设值,所述主载波对应的预设值小于或等于所述辅载波对应的预设值。例如,为主载波配置的预设值为3;为辅载波配置的预设值为5。可以看出终端设备在辅载波上接收到较多的控制信息的情况下,才能将辅载波上的长度长的DRX周期变更为长度短的DRX周期,这样可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
可选的,预设值是由无线资源控制RRC信令配置的。具体是接入网设备通过RRC信令将预设值发送给终端设备。
在4中介绍的可能实现方案中,第一DRX周期的长度比第二DRX周期的长度长,这样在相同的时间段中,采用第一DRX周期执行PDCCH监测的时长比采用第二DRX周期执行PDCCH监测的时长要长,因此,在终端设备需要将第一载波上长度长的DRX周期变更为长度短的DRX周期的情况下,保持其他载波上的DRX周期保持不变,可以减少其他载波执行PDCCH监测的时长。另外由于主载波上调度较多、较频繁,在激活的辅载波上调度较少、较稀疏,本申请实施例配置的辅载波对应的预设值较大,这样终端设备在辅载波上接收到较多的控制信息的情况下,才能将辅载波上的长度长的DRX周期变更为长度短的DRX周期,这样可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
结合以上图3的无线通信方法4中介绍的方案,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,如果在Pcell上drx-Long Cycle中有一个drx-Inactivity Timer超时或者Pcell上drx-Long Cycle中收到一个PDCCH,则下一个cycle变为drx-Short Cycle。针对SCell而言,终端设备需要在一个drx-Long Cycle中收到N个PDCCH,N>1,即终端设备在drx-Long Cycle中收到控制信息个数大于等于N,则SCell的下一个cycle变为drx-Short Cycle。而如果终端设备在该drx-Long Cycle中收到控制信息个数小于N,则下一个cycle不变,依然是drx-Long Cycle。
可选的,当配置了drx-Long Cycle和drx-Short Cycle两种cycle时,在每个drx-Long Cycle中开启一个计数器,当计数器达到N值时,下一个cycle变为drx-Short Cycle。
由此可见,当Pcell上drx-Long Cycle中收到一个PDCCH时,Pcell的下一个cycle变为drx-Short Cycle;Scell上drx-Long Cycle中收到一个以上的PDCCH时,Scell的下一个cycle变为drx-Short  Cycle,因此本申请实施例的方案可以减少Scell中drx-Short Cycle的配置,从而达到减少对PDCCH的监测的目的。
5、一种可能的实现方案中,在以上1、2、3、4方案中的第一DRX周期和第二DRX周期均包括持续时间(on-duration)。不同载波对应的on-duration长度不同。
所述多个载波包括主载波和辅载波;在相同的DRX周期中所述主载波对应的on-duration长度大于所述辅载波对应的on-duration长度。
请参见图7,为本申请实施例提供了一种不同载波的DRX周期的示例图。如图7所示,主载波和辅载波都是以DRX周期进行非连续接收,其中,主载波的on-duration长度大于所述辅载波对应的on-duration长度。这样对于同一个DRX周期,可以减少辅载波对PDCCH的监测,进而减少了终端设备的功耗。
可选的,不同辅载波对应的on-duration长度可以不同。
结合以上图3的无线通信方法5中介绍的方案,可以实现为Pcell和Scell配置两组drx-onDurationTimer值或者从一组值内选取两个不同的drx-onDurationTimer值,Pcell配置的drx-onDurationTimer值大于等于Scell配置的drx-onDurationTimer值。并且Pcell和SCell的DRX cycle长度相同,周期频率相同,Pcell和Scell的onDuration的起始位置对齐(align)。这样可以减少Scell在onDuration内对PDCCH的监测,达到降低功耗的目的。
需要说明的是,针对图3描述的实现方案中涉及的接收到控制信息具体是指成功解码承载于PDCCH的数据包。
请参见图8,为本申请实施例提供了一种可能的无线通信方法的流程示意图。
801,终端设备在第一载波的第一时间段内监测物理下行控制信道PDCCH,第一载波为多个载波中的任意一个载波。
802,终端设备在第一载波的所述第一时间段内接收到控制信息的情况下,在第二时间段内所述终端设备只在所述第一载波监测所述PDCCH。
在载波聚合的场景中,终端设备可以在多个载波接收和发送数据。该终端设备可以在多个载波上按照DRX周期进行非连续接收,以实现对PDCCH的监测。其中,多个载波在同一时间段内所采用的DRX周期可以全部相同、也可以部分相同,例如,终端设备在第一载波以第一DRX周期监测所述PDCCH,多个载波中除第一载波之外的其他载波以第一DRX周期或以第二DRX周期监测所述PDCCH,以监测是否接收到控制信息,该控制信息承载于PDCCH。多个载波的on-duration在时间上可以不完全对齐,表示多个载波的on-duration在时间上可以完全不对齐,或者可以部分载波的对齐,本申请实施例对此不做限定。
如果终端设备在第一载波的所述第一时间段内接收到控制信息的情况下,在第二时间段内所述终端设备只在所述第一载波监测所述PDCCH,对于其他在第一时间段内没有接收到控制信息的载波上不执行PDCCH的监测。这样可以减少没有接收到控制信息的载波对PDCCH的监测,降低了终端设备的功耗。
可行的实现方案中,在第一载波的所述第一时间段内接收到控制信息的情况下,在第二时间段内所述终端设备只在所述第一载波监测所述PDCCH,且在所述第二时间段内所述终端设备在除第一载波外的其他载波不监测所述PDCCH。其中,所述第二时间段与所述第一时间段的时间不重叠。
以下针对不同的情况对图8所示的无线通信方法的具体实现方案进行详细介绍。
1、在一种可能的实现方案中,所述终端设备在第一载波的所述第一时间段内接收到控制信息的情况下,在所述多个载波上启动或者重启第一定时器,在所述第一定时器启动或重启之后所述终端设备在第二时间段内只在所述第一载波监测所述PDCCH,在第二时间段内除第一载波外的其他载波不监测所述PDCCH。
其中,所述第一定时器的启动时刻不晚于所述第二时间段的开始时刻;所述第一定时器的结束时刻与所述第二时间段的结束时刻相同。
请参见图9,为本申请实施例提供了一种不同载波的DRX周期的示例图。如图9所示,第一载波和第二载波均以DRX周期进行非连续接收,第一载波、第二载波分别为多个载波中的任意一个载波。
如图9所示,终端设备在第一载波的on-duration内的T91时刻接收到了控制信息,终端设备在第一载波和第二载波的T91时刻均启动第一定时器;接着终端设备在第一载波的第一定时器的时间段内进 行监测PDCCH,且终端设备在第二载波上的这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。这一情形下的第二时间段为on-duration的结束时刻开始至第一定时器的结束时刻,参见图9中在这一个DRX周期内的灰色区域。可以看出,在第二载波上仅在on-duration期间进行PDCCH监测,在这一个DRX周期内多个载波中除第一载波之外的其他载波可以按照第二载波的方式执行,这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
接着,如图9所示,终端设备在第二载波的on-duration内的T92时刻接收到了控制信息,则终端设备在第一载波和第二载波的T91时刻均启动第一定时器,终端设备在第一载波的从T91时刻启动的第一定时器的时间段内进行监测PDCCH,以及终端设备在第二载波上在这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。接着,终端设备在第二载波的T93时刻接收到控制信息,则终端设备在第一载波和第二载波的T93时刻重启第一定时器,终端设备在第二载波的从T93时刻启动的第一定时器的时间段内进行监测PDCCH,且终端设备在第一载波上在这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。这一情形下的第二时间段为on-duration的结束时刻开始至从T93时刻重启的第一定时器的结束时刻,参见图9中在这一个DRX周期内的灰色区域。可以看出,终端设备在第一载波上仅在on-duration期间进行PDCCH监测,在这一个DRX周期内多个载波中除第二载波之外的其他载波可以按照第一载波的方式执行,这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
可选的,图9中的第一载波、第二载波并不区分主载波或者辅载波。
在1中介绍的可能实现方案中,在第一载波上接收到控制信息的情况下,终端设备在第二时间段内仅在第一载波上执行PDCCH监测,且在所述第二时间段内所述终端设备在除第一载波外的其他载波不监测所述PDCCH。这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
结合以上图8的无线通信方法1中介绍的方案,终端设备在所有载波的DRX on duration期间都监测PDCCH,如果终端设备在某一个载波的DRX on duration期间或者Inactivity Timer内收到控制信息,所有载波都启动或者重启Inactivity Timer,但终端设备只在接收到控制信息的载波上的Inactivity Timer内监测PDCCH;而在on duration或者Inactivity Timer内没有收到控制信息的载波上,只启动或者重启的Inactivity Timer,但不进行PDCCH的监测。而现有的方案是终端设备在所有载波的DRX on duration期间都监测PDCCH,且在任意一个载波的DRX on duration期间或者Inactivity Timer内接收到控制信息后,所有载波启动或者重启Inactivity Timer,并在所有载波的Inactivity Timer内监测PDCCH。由此可见,本申请实施例的方案在on duration期间或者Inactivity Timer内没有接收到控制信息的载波上的drx-Inactivity Timer内不进行PDCCH的监测,从而降低了终端设备监测PDCCH的功耗。
2、在一种可能的实现方案中,终端设备在第一载波的所述第一时间段内接收到控制信息的情况下,在所述第一载波上启动或者重启第一定时器,且在除第一载波外的其他载波上不启动或者重启第一定时器。其中,所述第一定时器用于监测所述PDCCH。当所述第一定时器启动或重启时,所述终端设备开始监测PDCCH。这样在所述第一定时器启动或重启之后所述终端设备在第二时间段内只在所述第一载波监测所述PDCCH,在除第一载波外的其他载波不监测所述PDCCH。
请参见图10,为本申请实施例提供了一种不同载波的DRX周期的示例图。如图10所示,第一载波和第二载波均以DRX周期进行非连续接收,第一载波、第二载波分别为多个载波中的任意一个载波。
如图10所示,终端设备在第一载波的on-duration内的T01时刻接收到了控制信息,终端设备在第一载波的T01时刻启动第一定时器;接着终端设备在第一载波的第一定时器的时间段内进行监测PDCCH,且终端设备在第二载波上的这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。这一情形下的第二时间段为on-duration的结束时刻开始至第一定时器的结束时刻,参见图10中在这一个DRX周期内的灰色区域。可以看出,在第二载波上仅在on-duration期间进行PDCCH监测,在这一个DRX周期内多个载波中除第一载波之外的其他载波可以按照第二载波的方式执行,这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
接着,如图10所示,终端设备在第二载波的on-duration内的T02时刻接收到了控制信息,则终端设备在第二载波的T01时刻启动第一定时器,终端设备在第二载波的从T01时刻启动的第一定时器的时间段内进行监测PDCCH,且终端设备在第一载波上在这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。接着,终端设备在第二载波的T03时刻接收到控制信息,则终端设备在第二载波的T03时刻重启第一定时器,终端设备在第二载波的从T03时刻启动的第一定时器的时间段内进行监测 PDCCH,且终端设备在第一载波上在这个DRX周期内从on-duration的结束时刻开始不执行PDCCH监测。这一情形下的第二时间段为on-duration的结束时刻开始至从T03时刻重启的第一定时器的结束时刻,参见图10中在这一个DRX周期内的灰色区域。可以看出,终端设备在第一载波上仅在on-duration期间进行PDCCH监测,在这一个DRX周期内多个载波中除第二载波之外的其他载波可以按照第一载波的方式执行,这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
在2中介绍的可能实现方案中,在第一载波上接收到控制信息的情况下,终端设备在第二时间段内仅在第一载波上执行PDCCH监测,且在所述第二时间段内所述终端设备在除第一载波外的其他载波不监测所述PDCCH。这样减少了终端设备在其他载波上的PDCCH监测,进而降低了终端设备的功耗。
结合以上图8的无线通信方法2中的方案,终端设备在所有载波的DRX on duration期间都监测PDCCH,但终端设备只在DRX on duration或者Inactivity Timer内收到控制信息的载波上启动或者重启Inactivity Timer,并在该Inactivity Timer进行PDCCH的监测;而在DRX on duration或者Inactivity Timer内没有收到控制信息的载波上,不启动Inactivity Timer,也不进行PDCCH的监测。而现有的方案是终端设备在所有载波的C-DRX on duration期间都监测PDCCH,且在任意一个载波的C-DRX on duration期间或者Inactivity Timer内接收到控制信息后,所有载波启动Inactivity Timer,并在所有载波的Inactivity Timer内监测PDCCH。由此可见,本申请实施例的方案只在C-DRX on duration期间或者Inactivity Timer内接收到控制信息的载波上启动或者重启drx-Inactivity Timer,并在该drx-Inactivity Timer内监测PDCCH,而在on duration期间或者Inactivity Timer内没有接收到控制信息的载波上不启动或者重启drx-Inactivity Timer,也不进行PDCCH的监测,从而降低了终端设备监测PDCCH的功耗。
结合图3至图8实施例所描述的方案,在一种可能的实现方案中,终端设备在第一载波的DRX on duration或者inactivity Timer内收到控制信息时,所有载波都启动或者重启inactivity Timer,但在on duration或者inactivity Timer内没有收到控制信息的载波上,在启动或者重启的inactivity Timer内不进行PDCCH的监测。
在另一种可能的实现方案中,终端设备在第一载波的DRX on duration或者inactivity Timer内收到控制信息时,只在收到控制信息的载波上启动或者重启inactivity Timer并进行PDCCH的监测;而在on duration或者inactivity Timer内没有收到控制信息的载波上,不启动inactivity Timer,也不进行PDCCH的监测。
在另一种可能的实现方案中,当配置了drx-Long Cycle和drx-Short cycle两种cycle时,当终端设备在某个载波的drx-Long Cycle中的drx-Inactivity Timer超时时或者终端设备在drx-Long Cycle中的on duration期间收到控制信息时,则该载波的下一个cycle从drx-Long Cycle转变成drx-Short cycle,其他载波的drx-Cycle不变。
在另一种可能的实现方案中,当配置了drx-Long Cycle和drx-Short cycle两种cycle时,Pcell不变,针对SCell,终端设备需要在一个drx-Long Cycle中收到N个PDCCH,N>1,即终端设备在drx-Long Cycle中收到控制信息个数大于等于N,则SCell的下一个cycle变为drx-Short Cycle。
在另一种可能的实现方案中,当配置了drx-Long Cycle和drx-Short cycle两种cycle时,为Pcell和Scell配置两套不同的drx-long Cycle Timer值,可选的,不同的Scell的drx-Long Cycle Timer值可以相同也可以不同
在另一种可能的实现方案中,当配置了drx-Long Cycle和drx-Short cycle两种cycle时,为Pcell和Scell配置两组不同的drx-Short cycle timer值,可选的,不同的Scell的drx-Short cycle timer值可以相同也可以不同。在另一种可能的实现方案中,当配置了drx-Long Cycle和drx-Short cycle两种cycle时,为Pcell和Scell配置两组不同的drx-on durationTimer值,DRX cycle长度相同,且周期频率相同,Pcell和Scell的on duration的起始位置是对齐的。可选的,不同的Scell的drx-on durationTimer值可以相同也可以不同。
上述可能的实现方案均可以降低终端设备监测PDCCH的功耗。
