Description

波束失败恢复方法、设备及系统
本申请要求于2019年08月09日提交国家知识产权局、申请号为201910735784.5、申请名称为“波束失败恢复方法、设备及系统”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,尤其涉及波束失败恢复方法、设备及系统。
背景技术
第五代(5th generation,5G)移动通信系统采用基于模拟波束的高频通信,模拟波束的信号覆盖范围较窄,容易被障碍物遮挡而发生波束失败(beam failure)。
鉴于上述问题,在5G系统的版本(release,Rel)15中,提出了波束失败恢复(beam failure recovery,BFR)流程,该流程包括:网络设备为终端设备配置一组用于波束失败检测的波束失败检测资源和一组用于确定当前波束的备选波束的备选波束资源。当终端设备检测到该组波束失败检测资源中的每个资源的质量都低于门限1时,确定发生波束失败。其中,在对应的一组备选波束资源中存在质量高于门限2的资源时,终端设备可以确定一个备选波束进行波束失败恢复,该备选波束为一组备选波束资源中质量高于门限2的一个备选波束资源对应的波束。
然而,在某些场景下,可能需要在一个小区内配置多组波束失败检测资源和多组备选波束资源,用于局部波束失败检测和恢复。例如,一个小区包括多个传输接收节点(transmission reception point,TRP)时,需要针对每个TRP进行波束失败的检测和恢复。在该类场景下,若采用上述方法进行波束失败恢复,由于终端设备在网络设备配置的所有波束失败检测资源的质量都低于门限1时,才确定发生波束失败并进行波束失败恢复,从而导致终端设备不能及时地进行波束失败恢复。
发明内容
本申请实施例提供一种波束失败恢复方法、设备及系统,可以及时地对波束失败进行恢复。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供了一种波束失败恢复方法及相应的装置。该方案中,终端设备接收来自网络设备的配置信息,并根据该配置信息确定M个波束失败检测资源组和N个备选波束资源组,M和N为正整数,且M和N不同时为1。在第一波束失败检测资源组中的每个波束失败检测资源的质量均低于第一门限值的情况下,或者在第一波束失败检测资源组中所有波束失败检测资源的平均质量低于第一门限值的情况下,或者在第一波束失败检测资源组中质量低于第一门限值的波束失败检测资源的数量大于预设值的情况下,终端设备从第一备选波束资源组中确定质量高于第二门限值的一个或多个备选波束资源,并向网络设备发送第一指示信息。其中,该第一指示信息用于指示第一备选波束资源,该第一备选波束资源为上述一个或多个备选波束资源中的备选波束资源,第一波束失败检测资源组为该M个波束失败检测资源组中的任意一个波束失败检测资源组,第一备选波束资源组为该N个备选波束资源组中与所述第一波束失败检测资源组关联的备选波束资源组。
需要说明的是,本申请实施例中,“终端设备从第一备选波束资源组中确定质量高于第二 门限值的一个或多个备选波束资源”可以理解为“第一备选波束资源组中存在质量高于第二门限值的一个或多个备选波束资源”,二者可以相互替换。
基于该方案,一方面,终端设备确定任意一个波束失败检测资源组发生波束失败时,即从该波束失败检测资源组关联的备选波束资源组中确定质量高于第二门限值的备选波束资源,并向网络设备发送第一指示信息进行波束失败恢复,因此,终端设备无需等到该小区的M个波束失败检测资源组均发生波束失败时才进行波束失败恢复;另一方面,由于M个波束失败检测资源组中的每个波束失败检测资源组关联N个备选波束资源组中的备选波束资源组,因此,可以针对每一组波束失败检测资源进行恢复。综上,基于本申请实施例提供的波束失败恢复方法,可以及时对失败波束进行恢复,当M个波束失败检测资源组以TRP为粒度时,即可实现TRP粒度的波束失败恢复,从而提高多TRP传输的性能。

其中,配置信息用于网络设备向终端设备指示波束失败恢复的相关配置,主要包括波束失败检测资源和备选波束资源的配置,波束失败检测资源用于波束失败检测,备选波束资源用于识别新的可用波束。
需要说明的是,本申请实施例中仅是示例性的将用于波束失败检测的资源称为波束失败检测资源,将用于识别新的可用波束的资源称为备选波束资源,具体实现中用于波束失败检测的资源和/或用于识别新的可用波束的资源也可以有其他名称,本申请实施例并不对上述两类资源的名称进行具体限定。
其中,本申请实施例中,针对单个小区,网络设备可以通过配置信息向终端设备配置M个波束失败检测资源组和N个备选波束资源组,该N个备选波束资源组包括该M个波束失败检测资源组中的每个波束失败检测资源组所关联的备选波束资源组,M和N为正整数。
可选的,本申请实施例中,网络设备配置的M个波束失败检测资源组中的任意一个波束失败检测资源组可以与N个备选波束资源组中的一个备选波束资源组关联,即波束失败检测资源组与备选波束资源组的关联关系为一对一;或者,一个波束失败检测资源组也可以与多个备选波束资源组关联,即波束失败检测资源组与备选波束资源组的关联关系为一对多;或 者,多个波束失败检测资源组还可以与一个相同的备选波束资源组关联,即波束失败检测资源组与备选波束资源组的关联关系为多对一,本申请实施例对此不做具体限定。
需要说明的是,当波束失败检测资源组与备选波束资源组的关联关系为一对一时,M和N均大于1;当波束失败检测资源组与备选波束资源组的关联关系为一对多或多对一时,M和N中至少一个大于1。也就是说,本申请实施例中,M和N不同时为1,例如,M和N均可以为大于或者等于2的正整数。
S502、终端设备根据配置信息确定M个波束失败检测资源组和N个备选波束资源组。
可选的,终端设备接收到上述配置信息后,根据配置信息确定M个波束失败检测资源组和N个备选波束资源组,以及波束失败检测资源组与备选波束资源组的关联关系。
S503、终端设备进行波束失败恢复条件判决。
可选的,终端设备确定M个波束失败检测资源后,分别测量M个波束失败检测资源组中的每个波束失败检测资源组,进而判断是否需要进行波束失败恢复。
其中,在上述步骤S501中:
可选的,本申请实施例中,网络设备配置的M个波束失败检测资源组的分组可以以TRP为粒度,即每个波束失败检测资源组对应一个TRP;或者,也可以以其他标准为粒度,例如以比TRP更细的粒度进行分组,例如多个波束失败检测资源组对应一个TRP,本申请实施例对此不做具体限定。
下面以波束失败检测资源组的粒度为TRP为例,分别对M个波束失败检测资源组的配置方式、N个备选波束资源组的配置方式、以及波束失败检测资源组与备选波束资源组的关联关系的建立方式进行说明。
可选的,本申请实施例中,网络设备可以通过如下三种方式向终端设备配置波束失败检测资源:
方式一、配置信息中包括M个波束失败检测资源组,该M个波束失败检测资源组中的每个波束失败检测资源组包括一个或多个波束失败检测资源。
在方式一中,示例性的,配置信息中的每个波束失败检测资源组可以配置成以下形式:
波束失败检测资源组(例如,RadioLinkMonitoringRSSet){
波束失败检测资源组索引(例如,RadioLinkMonitoringRSSetID),
波束失败检测资源列表(例如,RadioLinkMonitoringRSList)
}
其中,波束失败检测资源组索引用于标识该波束失败检测资源组,波束失败检测资源列表中包括一个或多个波束失败检测资源。
方式二、配置信息包括X个波束失败检测资源,该X个波束失败检测资源中的每个波束失败检测资源均关联一个第一索引,X为大于或者等于M的正整数。
其中,该X个波束失败检测资源为构成该M个波束失败检测资源组的波束失败检测资源。具体的,该X个波束失败检测资源中,关联相同的第一索引的一个或多个波束失败检测资源属于同一个波束失败检测资源组,此时可以认为该一个波束失败检测资源组关联第一索引。
可选的,上述第一索引可以为以下任意一种:TRP的索引、控制资源集合(control resource set,CORESET)的索引、CORESET组的索引、时间提前组(timing advance group,TAG)的索引、解调参考信号(demodulation reference signal,DMRS)端口的索引、DMRS端口组的索引、用于CORESET分组的索引、用于生成混合自动重传请求(hybrid automatic repeat request,HARQ)码本的索引、加扰索引(scrambling ID)、波束失败恢复配置索引、备选波 束资源组的索引、备选波束资源的索引、物理上行控制信道(physical uplink control channel,PUCCH)资源索引、PUCCH资源组的索引、探测参考信号(sounding reference signal,SRS)资源组的索引、时隙索引、或子时隙(sub-slot)索引。该加扰索引可以是物理下行控制信道(physical downlink control channel,PDCCH)或物理下行共享信道(physical downlink share channel,PDSCH)或PUCCH或物理上行共享信道(physical uplink share channel,PUSCH)的加扰索引。
其中,TRP的索引用于标识一个TRP,X个波束失败检测资源中,关联相同TRP的索引的一个或多个波束失败检测资源即构成该TRP对应的一个波束失败检测资源组;
其中,CORESET的索引、CORESET组的索引、TAG的索引、DMRS端口的索引、DMRS端口组的索引、用于CORESTE分组的索引、用于生成HARQ码本的索引、PUCCH资源索引、PUCCH资源组的索引、SRS资源组的索引、时隙索引、或子时隙(sub-slot)索引、以及加扰索引均与TRP关联。网络设备可以为不同的TRP配置不同的上述索引,因此,通过配置波束失败检测资源与上述各个索引关联,也可以确定出各个TRP对应的波束失败检测资源组。
示例性的,以第一索引为CORESET组的索引为例,网络设备可以为TRP1配置CORESET组索引1,为TRP2配置CORESET组索引2,则X个波束失败检测资源中关联CORESTE组索引1的一个或多个波束失败检测资源即构成TRP1对应的波束失败检测资源组,关联CORESTE组索引2的一个或多个波束失败检测资源即构成TRP2对应的波束失败检测资源组。
其中,波束失败恢复配置索引用于标识一个波束失败恢复配置,该波束失败恢复配置中包括上述N个备选波束资源组中一个或多个备选波束资源组的配置;备选波束资源组的索引用于标识上述N个备选波束资源组中的一个备选波束资源组;备选波束资源的索引用于标识上述N个备选波束资源组中的一个备选波束资源。
可选的,在方式二中,第一索引可以作为波束失败检测资源的一个参数。示例性的,配置信息中的每个波束失败检测资源可以配置成以下形式:
波束失败检测资源(例如,RadioLinkMonitoringRS){
波束失败检测资源的索引(例如,RadioLinkMonitoringRS-Id),
第一索引
}
上述两种方式可以认为是直接配置的M个波束失败检测资源组,可选的,该M个波束失败检测资源组也可以通过如下方式三间接配置:
方式三、配置信息包括M个CORESET组或者构成M个CORESET组的K个CORESTE,K为大于或者等于M的正整数。
其中,该M个COERSET组中的每个CORESET组分别用于确定一个波束失败检测资源组。该每个CORESET组可以分别关联不同的TRP,可以理解一个CORESET组确定的一个波束失败检测资源组为该CORESET组关联的TRP对应的波束失败检测资源组。
可选的,每个CORESET组分别用于确定一个波束失败检测资源组包括:每个CORESE组中所有CORESET当前激活的传输配置索引状态(transmission configuration index,TCI-state)中的第一参考信号资源属于一个波束失败检测资源组。其中,若一个CORESET当前激活的TCI-state中仅包括一个参考信号资源,则第一参考信号资源即为该一个参考信号资源;若一个CORESET当前激活的TCI-state中包括多个参考信息资源,则第一参考信号为该TCI-state中类型为typeD的准同位信息(quasi collocation information,QCL-Info)中的参考信号资源。
示例性的,以第一CORESET组包括CORESET#1和CORESET#2,且CORESET#1和CORESET#2当前激活的TCI-state中仅包括一个参考信号资源为例,该第一CORESET组确定的一个波束失败检测资源组即包括CORESET#1当前激活的TCI-state中包括的参考信号资源和CORESET#2当前激活的TCI-state中包括的参考信号资源。其中,第一CORESET组可以为M个CORESET组中的任意一个CORESET组。
可选的,在配置信息包括M个CORESET组的情况下,该M个CORESET组中的每个CORESET组分别关联不同的TRP可以包括:每个CORESET组分别关联不同的TRP关联索引,该TRP关联索引可以为以下任意一种:TRP的索引、CORESET的索引、CORESET组的索引、TAG的索引、DMRS端口的索引、DMRS端口组的索引、用于CORESET分组的索引、用于生成HARQ码本的索引、加扰索引、波束失败恢复配置索引、备选波束资源组的索引、备选波束资源的索引、PUCCH资源索引、PUCCH资源组的索引、SRS资源组的索引、时隙索引、或子时隙(sub-slot)索引。其中,各个索引的说明可参考上述第一索引中各个索引的说明,在此不再赘述。网络设备可以为不同的CORESET组配置不同的TRP关联索引,因此,通过不同的CORESET组确定的波束失败检测资源组分别对应不同的TRP。
可选的,在配置信息包括构成M个CORESET组的K个CORESET的情况下,该K个CORESTE中的每个CORESET可以关联一个TRP关联索引,关联相同TRP关联索引的一个或多个CORESET属于一个CORESET组。
或者,可选的,在配置信息包括构成M个CORESET组的K个CORESET的情况下,该K个CORESTE中的每个CORESET可以包括一个CORESET索引。其中,CORESET索引为奇数的一个或多个CORESET属于一个CORESET组,CORESET索引为偶数的一个或多个CORESET属于一个CORESET组;或者,CORESET索引对M取模后结果相同的CORESET属于一个CORESET组;或者,将K个CORESET的索引按照预设规则排序后,每K除M个CORESET索引对应的CORESET属于一个CORESET组,当K不能整除M时,可以将K除以M的结果向上取整或者向下取整后再进行分组。例如,K为5,M为2时,需要将5个CORESET分组两组,此时,若采用向上取整的方式进行分组,则排序后前3个CORESET索引对应的3个CORESET为一组,后2个CORESTE索引对应的2个CORESET为一组,若采用向下取整的方式进行分组,则排序后的前2个CORESET索引对应的2个CORESET为一组,后3个CORESTE索引对应的3个CORESET为一组。
可选的,上述预设规则可以为将K个CORESTE的索引从小到大进行排序;或者,将K个CORESTE的索引从大到小进行排序;或者,将K个CORESET根据网络设备配置该K个CORESET的先后顺序进行排序。
可选的,由于索引为0的CORESET用于接收系统信息块(system information blocks,SIB)1对应的下行控制信息,可以被多个TRP共用,因此上述K个CORESET中可以不包括索引为0的CORESET。
可选的,本申请实施例中,网络设备可以通过如下两种方式向终端设备配置备选波束资源:
方式一、配置信息中包括N个备选波束资源组,该N个备选波束资源组中的每个备选波束资源组包括一个或多个备选波束资源。
在方式一中,示例性的,配置信息中的每个备选波束资源组可以配置成以下形式:
备选波束资源组(例如,candidateBeamRSSet){
备选波束资源组索引(例如,candidateBeamRSSetID),
备选波束资源列表(例如,candidateBeamRSlist)
}
其中,备选波束资源组索引用于标识该备选波束资源组,备选波束资源列表中包括一个或多个备选波束资源。
方式二、配置信息包括Y个备选波束资源,该Y个备选波束资源中的每个备选波束资源均关联一个第二索引,Y为大于或者等于N的正整数。
其中,该Y个备选波束资源为构成该N个备选波束资源组的资源,具体的,该Y个备选波束资源中,关联相同的第二索引的一个或多个备选波束资源属于同一个备选波束资源组,此时可以认为该一个备选波束资源组关联第二索引。
可选的,上述第二索引可以为以下任意一种:TRP的索引、CORESET的索引、CORESET组的索引、TAG的索引、DMRS端口的索引、DMRS端口组的索引、用于CORESET分组的索引、用于生成HARQ码本的索引、加扰索引、波束失败恢复配置索引、波束失败检测资源组的索引、波束失败检测资源的索引、PUCCH资源索引、PUCCH资源组的索引、SRS资源组的索引、时隙索引、或子时隙(sub-slot)索引。
其中,上述任意一种索引的相关说明可参考M个波束失败检测资源组的配置方式中相同索引的相关描述,在此不再赘述。
一种可能的实现方式中,Y个备选波束资源可以包含在配置信息中的一个波束失败恢复配置中,第二索引可以作为备选波束资源的一个参数。示例性的,波束失败恢复配置可以配置成以下形式:
波束失败恢复配置(例如,BeamFailureRecoveryConfig){
备选波束资源列表(例如,candidateBeamRSList)
}
其中,备选波束资源列表中包括Y个备选波束资源。示例性的,波束失败恢复配置中包括的备选波束资源可以配置成以下形式:备选波束资源(例如,candidateBeamRS){
备选波束资源索引(例如,candidateBeamRSID),

}
另一种可能的实现方式中,Y个备选波束资源可以包含在配置信息中的多个波束失败恢复配置中。
上述实施例对波束失败检测资源组和备选波束资源组的配置方式进行了说明,下面对上述各个配置方式下,波束失败检测资源组与备选波束资源组的关联关系的配置进行说明。可选的,可能存在如下几种情况:

一种可能的实现方式中,可以在波束失败检测资源组中配置备选波束资源组的索引,表示该备选波束资源组与该波束失败检测资源组关联,例如,在每个波束失败检测资源组中包括一个备选波束资源组的索引,即波束失败检测资源组可以配置成以下形式:
波束失败检测资源组(例如,RadioLinkMonitoringRSSet){
波束失败检测资源组索引(例如,RadioLinkMonitoringRSSetID),
波束失败检测资源列表(例如,RadioLinkMonitoringRSList)),
备选波束资源组索引(例如,candidateBeamRSList)
}
在该情况下,可选的,每个波束失败检测资源组中可以仅包括一个备选波束资源组索引,此时,波束失败检测资源组与备选波束资源组的对应关系为一一对应;或者,每个波束失败检测资源组中还可以包括多个备选波束资源组索引,此时,波束失败检测资源组与备选波束资源组的对应关系为一对多;或者,多个不同的波束失败检测资源组中的备选波束资源组的索引可以相同,此时,波束失败检测资源组与备选波束资源组的对应关系为多对一,本申请实施例对此不做具体限定。
另一种可能的实现方式中,波束失败检测资源组中可以包括波束失败恢复配置的索引,表示该波束失败检测资源组与该波束失败恢复配置关联,由于备选波束资源包括在波束失败恢复配置中,因此该波束失败检测资源组与该波束失败恢复配置关联也可以理解为该波束失败检测资源组与该波束失败恢复配置包含的备选波束资源组成的备选波束资源组关联。
又一种可能的方式中,备选波束资源组中可以包括波束失败检测资源组的索引,表示该波束失败检测资源组与该备选波束资源组关联。可选的,备选波束资源组中可以包括一个或多个波束失败检测资源组的索引,或者多个不同的备选波束资源组中包括的波束失败检测资源组的索引可以相同。
再一种可能的方式中,波束失败恢复配置中可以包括波束失败检测资源组的索引,表示该波束失败检测资源组与该波束失败恢复配置关联,由于备选波束资源包括在波束失败恢复配置中,因此该波束失败检测资源组与该波束失败恢复配置关联也可以理解为该波束失败检测资源组与该波束失败恢复配置包含的备选波束资源组成的备选波束资源组关联。可选的,波束失败恢复配置中可以包括一个或多个波束失败检测资源组的索引,或者多个不同的波束失败恢复配置中包括的波束失败检测资源组的索引可以相同。
方式二、分别在波束失败检测资源组和备选波束资源组中配置一个第三索引,当波束失败检测资源组和备选波束资源组关联的第三索引相同时,该波束失败检测资源和该备选波束资源关联。

第三索引
}
情况二、M个波束失败检测资源组通过方式一配置,N个备选波束资源组通过方式二配置。
可选的,在该情况二下,波束失败检测资源组与备选波束资源组的关联关系可以通过以下两种方式建立:
方式一、当备选波束资源关联的第二索引为波束失败检测资源组的索引时,在根据第二索引确定N个备选波束资源组时,波束失败检测资源组与备选波束资源组的关联关系已经建立,即关联相同波束失败检测资源组的索引的一个或多个备选波束资源构成一个备选波束资源组,该备选波束资源组关联的波束失败检测资源组即为该第二索引对应的波束失败检测资源组,此时,也可以认为该波束失败检测资源组与该备选波束资源组直接关联。
方式二、当备选波束资源关联的第二索引为TRP的索引时,可以在波束失败检测资源组中也配置一个TRP的索引。
在该情况下,可选的,关联相同TRP的索引的一个或多个备选波束资源构成一个备选波束资源组,该备选波束资源组关联的波束失败检测资源组为配置了该相同TRP的索引的波束失败检测资源组,此时,也可以认为该波束失败检测资源组与该备选波束资源组均关联相同的第三索引,在该情况下,第三索引为TRP的索引。
可选的,可以在不同的波束失败检测资源组中配置相同TRP的索引,从而建立波束失败检测资源组与备选波束资源组的多对一的关联关系。
可以理解的是,当备选波束资源关联的第二索引为CORESET的索引、CORESET组的索引、TAG的索引、DMRS端口的索引、DMRS端口组的索引、用于CORESET分组的索引、用于生成HARQ码本的索引、加扰索引、波束失败恢复配置索引、波束失败检测资源的索引、PUCCH资源索引、时隙索引、或子时隙(sub-slot)索引中的任意一种时,波束失败检测资源组与备选波束资源组的关联关系的建立方式与该情况二中的方式二相同,在此不再赘述。
情况三、M个波束失败检测资源组通过方式二配置,N个备选波束资源组通过方式一配置。
可选的,在该情况三下,波束失败检测资源组与备选波束资源组的关联关系可以通过以下两种方式建立:
方式一、当波束失败检测资源关联的第一索引为备选波束资源组的索引时,在根据第一索引确定M个波束失败检测资源组时,波束失败检测资源组与备选波束资源组的关联关系已经建立,即关联相同备选波束资源组的索引的一个或多个波束失败检测资源构成一个波束失败检测资源组,该波束失败检测资源组关联的备选波束资源即为该第一索引对应的备选波束资源组,此时,也可以认为该波束失败检测资源组与该备选波束资源组直接关联。
方式二、当波束失败检测资源关联的第一索引为TRP的索引时,可以在备选波束资源组中也配置一个TRP的索引。
在该情况下,可选的,关联相同TRP的索引的一个或多个波束失败检测资源构成一个波束失败检测资源组,该波束失败检测资源组关联的备选波束资源组为配置了该相同的TRP的索引的备选波束资源组,此时,也可以认为该波束失败检测资源组与该备选波束资源组均关联相同的第三索引,在该情况下,第三索引为TRP的索引。
可选的,可以在不同的备选波束资源组中配置相同TRP的索引,从而建立波束失败检测资源组与备选波束资源组的一对多的关联关系。
可以理解的是,当波束失败检测资源关联的第一索引为CORESET的索引、CORESET组的索引、TAG的索引、DMRS端口的索引、DMRS端口组的索引、用于CORESET分组的索引、用于生成HARQ码本的索引、加扰索引、波束失败恢复配置索引、备选波束资源的索引、PUCCH资源索引、PUCCH资源组的索引、SRS资源组的索引,时隙或子时隙(sub-slot)索引中的任意一种时,波束失败检测资源组与备选波束资源组的关联关系的建立方式与该情况三中的方式二相同,在此不再赘述。
情况四、M个波束失败检测资源组通过方式二配置,N个备选波束资源组通过方式二配置。
可选的,在该情况四下,关联相同第一索引的一个或多个波束失败检测资源构成一个波束失败检测资源组,关联相同的第二索引的一个或多个备选波束资源构成一个备选波束资源,当该相同的第一索引和该相同的第二索引相同时,该一个波束失败检测资源与该一个备选波束资源关联,此时,也可以认为该波束失败检测资源组与该备选波束资源组均关联相同的第三索引,在该情况下,第三索引与第一索引和第二索引相同。
示例性的,以第一索引和第二索引均为TRP关联索引为例,若X个波束失败检测资源中,波束失败检测资源1和波束失败检测资源2均关联TRP关联索引1,则波束失败检测资源1和波束失败检测资源2构成波束失败检测资源组1,此时可以认为波束失败检测资源组1关联TRP关联索引1;若备选波束资源1和备选波束资源2均关联TRP关联索引1,则备选波束资源1和备选波束资源2构成备选波束资源组1,此时可以认为备选波束资源组1关联TRP关联索引1。由于波束失败检测资源组1和备选波束资源组1均关联TRP关联索引1,因此,可以认为波束失败检测资源组1关联备选波束资源组1。
情况五、M个波束失败检测资源组通过方式三确定。
