Description
本公开涉及通信技术领域,尤其涉及一种功能配置方法及装置、消息发送方法及装置、用户设备、基站和计算机可读存储介质。
目前,第三代合作伙伴计划(3rd Generation Partnership Project,简称为3GPP)正在展开关于第五代移动通信技术(5th Generation,简称为5G)新空口(new radio,简称为NR)的标准化工作,为了解决数据包或信令包传输的可靠性问题,3GPP已经通过了在用户面数据包汇聚协议(packet data convergence protocol,简称为PDCP)层的包复制方案。但由于PDCP层位于无线用户面协议栈最上层,PDCP包和PDCP复制包无法保证能够通过底层的两个载波来发送,这就带来一个问题:如果一个载波上的信号质量非常差且PDCP包和PDCP复制包均在该载波上发送,则发送成功的概率会很低。为了解决该问题,相关会议上提出了PDCP层包复制与载波结合的方案,通过建立承载分离(split bearer),也即在PDCP层以下将一个承载映射到两个或多个无线链路控制(RLC)实体上,从而可以将一个PDCP层映射到不同的逻辑信道上,进而可以实现将PDCP包和PDCP复制包映射到不同的物理载波上发送。
另外,对于开启了双连接的UE,也即同时和主基站与辅基站进行数据交互的UE,通过配置split bearer,可以将一数据承载(DRB)或信令承载(SRB)的数据在主基站(MCG)和辅基站(SCG)上传输。以前引入split bearer主要是用于主基站和辅基站传输同一个DRB或SRB的不同数据,辅基站起到分流的效果,可以增加吞吐量。但这种split bearer也可以用于PDCP包复制的场景,也即让辅基站传输PDCP复制包。

通过重置当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和或者重置当前PDCP PDU及其之前发送的PDCP PDU的个数,为后续是否在新的PDCP PDU中添加轮询指示提供依据。
通过向UE发送RRC消息,使得UE可以根据接收的RRC消息为DRB或SRB配置两个RLC实体以及PDCP包复制功能和分流功能的任一项,实现了一个DRB或SRB只能同时配置PDCP包复制功能和分流功能中的一种功能。
通过为DRB或SRB配置的两个RLC实体采用相同的RLC模式,可以降低PDCP层处理PDU时的复杂度,且可以降低基站接收PDCP PDU的时延。
通过将配置PDCP包复制功能的DRB对应的两个RLC实体的RLC模式配置为RLCUM模式,将配置PDCP包复制功能的SRB对应的两个RLC实体的RLC模式配置为RLC UM模式或RLC AM模式,可以减少无线资源的浪费。
通过接收UE发送的PDCP PDU,并按照预设时间间隔向UE发送PDCP PDU的反馈信息,使得UE在接收到PDCP PDU的反馈信息后,可以确定发送失败的PDCP PDU,并对发送失败的PDCP PDU进行重传。

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是本申请一示例性实施例示出的一种功能配置方法的流程图,该实施例从UE侧进行描述,如图1所示,该功能配置方法包括:
在步骤S101中,接收基站发送的无线资源控制RRC消息,该RRC消息中携带配置
信息,该配置信息指示为DRB或SRB配置两个RLC实体、以及以下任一项:PDCP包复制功能、分流功能。
其中,为DRB或SRB配置的两个RLC实体采用相同的RLC模式。在该实施例中,配置PDCP包复制功能的DRB对应的两个RLC实体均采用的RLC模式可以包括RLC非确认(UM)模式,配置PDCP包复制功能的SRB对应的两个RLC实体均采用的RLC模式可以包括RLC UM模式或RLC确认(AM)模式。
通过为DRB或SRB配置的两个RLC实体采用相同的RLC模式,可以降低PDCP层处理PDU时的复杂度,且可以降低基站接收PDCP PDU的时延。通过将配置PDCP包复制功能的DRB对应的两个RLC实体的RLC模式配置为RLC UM模式,将配置PDCP包复制功能的SRB对应的两个RLC实体的RLC模式配置为RLC UM模式或RLC AM模式,可以减少无线资源的浪费。
在步骤S102中,根据RRC消息为DRB或SRB配置两个RLC实体、以及以下任一项:PDCP包复制功能、分流功能。
在该实施例中,UE在接收RRC消息后,可以根据RRC消息进行相应的配置,例如,根据RRC消息为对应的DRB或SRB配置两个RLC实体和PDCP包复制功能,也可以根据RRC消息为对应的DRB或SRB配置两个RLC实体和分流功能。
上述实施例,通过根据接收的RRC消息为DRB或SRB配置两个RLC实体以及PDCP包复制功能和分流功能的任一项,实现了一个DRB或SRB只能同时配置PDCP包复制功能和分流功能中的一种功能。
图2是本申请一示例性实施例示出的另一种功能配置方法的流程图,如图2所示,在步骤S102之后,该功能配置方法还可以包括:
在步骤S103中,将配置PDCP包复制功能的DRB或SRB的所有PDCP PDU在对应的两个RLC实体上均进行发送。
假设DRB1配置了PDCP包复制功能,DRB1的所有PDCP PDU包括PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4,为DRB1配置的两个RLC实体为RLC实体1和RLC实体2,则在DRB1的PDCP包复制功能打开后,可以将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4在RLC实体1和RLC实体2上均进行发送。例如,将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4在RLC实体1上进行发送,将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4这四个PDU的复制包在RLC实体2上进行发送。
需要说明的是,对于配置分流功能的DRB或SRB,需要将其PDCP PDU划分成两部分,其中一部分在对应的一个RLC实体上发送,另一部分在对应的另一个RLC实体上发送。
在该实施例中,可以基于两个RLC实体的缓存状态或信道质量将PDCP PDU动态划分成两部分,例如,可以为缓存PDCP PDU比较多的RLC实体划分小部分数据,为缓存PDCP PDU比较少的RLC实体划分大部分数据。
通过将配置分流功能的DRB或SRB的PDCP PDU划分成两部分,其中一部分在对应的一个RLC实体上发送,另一部分在对应的另一个RLC实体上发送,可以提高发送速度和单位时间内成功发送的PDU数量。
上述实施例,通过将配置PDCP包复制功能的DRB或SRB的所有PDCP PDU在对应的两个RLC实体上均进行发送,可以提高发送成功率。
图3是本申请一示例性实施例示出的另一种功能配置方法的流程图,如图3所示,在步骤S103之后,该功能配置方法还可以包括:
在步骤S104中,针对配置PDCP包复制功能且对应的两个RLC实体采用RLC UM模式的DRB或SRB,对未成功发送的PDCP PDU进行重传。
其中,对未成功发送的PDCP PDU进行重传可以包括但不局限于以下至少一种情况:
第一种情况:若在当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,第一预设时长可以由RRC层配置。
在该实施例中,针对第一种情况可以包括以下一种或多种实现方式:
第一种实现方式:基站在接收UE发送的PDCP PDU后,可以按照预设时间间隔向UE发送PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
第二种实现方式:基站每接收UE发送的一个PDCP PDU,就向UE发送该PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
第三种实现方式:UE在生成某个PDCP PDU例如当前PDCP PDU时,若满足预定条件,则在当前PDCP PDU中添加轮询(polling)指示,并向基站发送当前PDCP PDU。基站接收到包含轮询指示的当前PDCP PDU后,根据该轮询指示向UE发送包含轮询指示的PDCP PDU及其之前接收的PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,上述预定条件可以包括但不局限于以下任一项:1)当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和达到第一预设数值;2)当前PDCP PDU及其之前发送的PDCP PDU的个数达到第二预设数值;3)在发送完当前PDCP PDU之后,发送窗口无法发送新的PDCP PDU;4)在发送完当前PDCP PDU之后,没有其他待发送的PDCP PDU。上述第一预设数值和第二预设数值可以由RRC层配置。
例如,UE先向基站发送PDCP PDU1和PDCP PDU2,之后生成PDCP PDU3,其中,若PDCP PDU1、PDCP PDU2和PDCP PDU3这三个PDU的数据部分的字节数达到第一预设数值,则可以在PDCP PDU3中添加轮询指示,并向基站发送PDCP PDU3。基站接收PDCP PDU3后,可以根据该轮询指示向UE发送PDCP PDU1、PDCP PDU2和PDCP PDU3的反馈信息。其中,UE在发送PDCP PDU1之后的第一预设时长内,未接收到基站发送的PDCP PDU1的反馈信息,则重传PDCP PDU1。
需要说明的是,若第二预定条件为当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和达到第一预设数值,则在当前PDCP PDU中添加轮询指示时,重置当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和。重置当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和是为了后续生成新的PDCP PDU时,统计之前发送的PDCP PDU和新的PDCP PDU的数据部分的字节数之和是否达到第一预设数值,进而为是否在新的PDCP PDU中添加轮询指示提供依据。类似地,若第二预定条件为当前PDCP PDU及其之前发送的PDCP PDU的个数达到第二预设数值,则在当前PDCP PDU中添加轮询指示时,重置当前PDCP PDU及其之前发送的PDCP PDU的个数。重置当前PDCP PDU及其之前发送的PDCP PDU的个数是为了后续生成新的PDCP PDU时,统计之前发送的PDCP PDU和新的PDCP PDU的个数之和是否达到第二预设数值,进而为是否在新的PDCP PDU中添加轮询指示提供依据。
第四种实现方式:若UE在向基站发送完除当前PDCP PDU之外的其他PDCP PDU超过第二预设时长之后,未接收到该PDCP PDU的反馈信息,则在生成当前PDCP PDU时,
在当前PDCP PDU中添加轮询指示,并向基站发送当前PDCP PDU。基站接收到包含轮询指示的当前PDCP PDU后,根据该轮询指示向UE发送包含轮询指示的PDCP PDU即当前PDCP PDU及其之前接收的PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,第二预设时长可以由RRC层配置。
例如,UE在向基站发送完PDCP PDU1超过第二预设时长之后,未接收到该PDCP PDU1的反馈信息,则在生成PDCP PDU2时,可以在PDCP PDU2中添加轮询指示,并向基站发送PDCP PDU2。基站接收PDCP PDU2后,可以根据该轮询指示向UE发送PDCP PDU1和PDCP PDU2的反馈信息。若UE在发送PDCP PDU2之后的第一预设时长内,接收到PDCP PDU2的反馈信息但PDCP PDU2的反馈信息指示基站未接收到PDCP PDU2,则重传PDCP PDU2。
第二种情况:若接收到的反馈信息中指示有基站未成功接收的PDCP PDU,则重传基站未成功接收的PDCP PDU。
在该实施例中,基站在重排序定时器超时后,向UE发送接收窗口内位于触发重排序定时器的PDCP PDU及其之前的PDCP PDU的反馈信息。若UE接收到的反馈信息中指示有基站未成功接收的PDCP PDU,则重传基站未成功接收的PDCP PDU。
例如,UE依次向基站发送PDCP PDU1、PDCP PDU2、PDCP PDU3、PDCP PDU4和PDCP PDU5,若基站在接收窗口内依次接收到PDCP PDU1、PDCP PDU2和PDCP PDU5,当接收到PDCP PDU5时,触发重排序定时器,即PDCP PDU5为触发重排序定时器的PDCP PDU,基站可以向UE发送PDCP PDU5及其之前的PDCP PDU的反馈信息,也即PDCP PDU1、PDCP PDU2、PDCP PDU3、PDCP PDU4和PDCP PDU5的反馈信息,其中,PDCP PDU3的反馈信息指示基站未成功接收PDCP PDU3,PDCP PDU4的反馈信息指示基站未成功接收PDCP PDU4,则UE向基站重传PDCP PDU3和PDCP PDU4。
由此可见,上述实施例,可以通过多种方式对未成功发送的PDCP PDU进行重传,实现方式灵活多样。
上述实施例,针对配置PDCP包复制功能且对应的两个RLC实体采用RLC UM模式的DRB或SRB,对未成功发送的PDCP PDU进行重传,可以实现对传输失败的数据进行重传,从而保证开启PDCP包复制功能的业务的可靠性。
图4是本申请一示例性实施例示出的一种消息发送方法的流程图,该实施例从基站侧进行描述,如图4所示,消息发送方法包括:
在步骤S401中,确定待配置PDCP包复制功能或分流功能的DRB或SRB。
在该实施例中,基站可以确定某个或某些DRB或SRB需要配置PDCP包复制功能和分流功能中的一种。
在步骤S402中,向UE发送RRC消息,该RRC消息中携带配置信息,该配置信息指示为数据承载DRB或信令承载SRB配置两个无线链路控制RLC实体、以及以下任一项:数据包汇聚协议PDCP包复制功能、分流功能。
在该实施例中,基站在确定待配置PDCP包复制功能或分流功能的DRB或SRB之后,可以向UE发送RRC消息,以在RRC消息中携带配置信息,该配置信息指示为数据承载DRB或信令承载SRB配置两个无线链路控制RLC实体、以及以下任一项:数据包汇聚协议PDCP包复制功能、分流功能。
其中,为DRB或SRB配置的两个RLC实体采用相同的RLC模式。在该实施例中,配置PDCP包复制功能的DRB对应的两个RLC实体均采用的RLC模式可以包括RLC UM模式,配置PDCP包复制功能的SRB对应的两个RLC实体均采用的RLC模式可以包括RLC UM模式或RLC AM模式。
上述实施例,通过向UE发送RRC消息,使得UE可以根据接收的RRC消息为DRB或SRB配置两个RLC实体以及PDCP包复制功能和分流功能的任一项,实现了一个DRB或SRB只能同时配置PDCP包复制功能和分流功能中的一种功能。
图5是本申请一示例性实施例示出的另一种消息发送方法的流程图,如图5所示,在上述步骤S402之后,该消息发送方法还可以包括:
在步骤S403中,接收UE发送的PDCP PDU,并按照预设时间间隔向UE发送PDCP PDU的反馈信息。
在该实施例中,基站在接收UE发送的PDCP PDU之后,可以按照预设时间间隔向UE发送PDCP PDU的反馈信息。
需要说明的是,除了步骤S403所示的方式,基站还可以采用以下任一方式向UE发送PDCP PDU的反馈信息:1)接收UE发送的PDCP PDU,并向UE发送PDCP PDU的反馈信息;2)若触发的重排序定时器超时,则向UE发送接收窗口内位于触发重排序定时器的
PDCP PDU及其之前的PDCP PDU的反馈信息;3)若接收到包含轮询指示的PDCP PDU,则根据轮询指示向UE发送包含轮询指示的PDCP PDU及其之前接收的PDCP PDU的反馈信息。
由此可见,本实施例可以通过多种方式向UE发送反馈信息,实现方式灵活多样。
UE在接收到PDCP PDU的反馈信息后,可以确定发送失败的PDCP PDU,并对发送失败的PDCP PDU进行重传。
上述实施例,通过接收UE发送的PDCP PDU,并按照预设时间间隔向UE发送PDCP PDU的反馈信息,使得UE在接收到PDCP PDU的反馈信息后,可以确定发送失败的PDCP PDU,并对发送失败的PDCP PDU进行重传。
图6是根据一示例性实施例示出的一种功能配置装置的框图,该功能配置装置可以位于UE中,如图6所示,该功能配置装置包括:接收模块61和配置模块62。
接收模块61被配置为接收基站发送的无线资源控制RRC消息,RRC消息中携带配置信息,配置信息指示为数据承载DRB或信令承载SRB配置两个无线链路控制RLC实体、以及以下任一项:数据包汇聚协议PDCP包复制功能、分流功能。
其中,为DRB或SRB配置的两个RLC实体采用相同的RLC模式。在该实施例中,配置PDCP包复制功能的DRB对应的两个RLC实体均采用的RLC模式可以包括RLC UM模式,配置PDCP包复制功能的SRB对应的两个RLC实体均采用的RLC模式可以包括RLC UM模式或RLC AM模式。
通过为DRB或SRB配置的两个RLC实体采用相同的RLC模式,可以降低PDCP层处理PDU时的复杂度,且可以降低基站接收PDCP PDU的时延。通过将配置PDCP包复制功能的DRB对应的两个RLC实体的RLC模式配置为RLC UM模式,将配置PDCP包复制功能的SRB对应的两个RLC实体的RLC模式配置为RLC UM模式或RLC AM模式,可以减少无线资源的浪费。

在该实施例中,UE在接收RRC消息后,可以根据RRC消息进行相应的配置,例如,根据RRC消息为对应的DRB或SRB配置两个RLC实体和PDCP包复制功能,也可以根据RRC消息为对应的DRB或SRB配置两个RLC实体和分流功能。
上述实施例,通过根据接收的RRC消息为DRB或SRB配置两个RLC实体以及PDCP包复制功能和分流功能的任一项,实现了一个DRB或SRB只能同时配置PDCP包复制功能和分流功能中的一种功能。
图7是根据一示例性实施例示出的另一种功能配置装置的框图,如图7所示,在上述图6所示实施例的基础上,该功能配置装置还可以包括:第一发送模块63或者第二发送模块64。
第一发送模块63被配置为将配置PDCP包复制功能的DRB或SRB的所有PDCP PDU在对应的两个RLC实体上均进行发送。
假设DRB1配置了PDCP包复制功能,DRB1的所有PDCP PDU包括PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4,为DRB1配置的两个RLC实体为RLC实体1和RLC实体2,则在DRB1的PDCP包复制功能打开后,可以将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4在RLC实体1和RLC实体2上均进行发送。例如,将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4在RLC实体1上进行发送,将PDCP PDU1、PDCP PDU2、PDCP PDU3和PDCP PDU4这四个PDU的复制包在RLC实体2上进行发送。
第二发送模块64被配置为将配置分流功能的DRB或SRB的PDCP PDU划分成两部分,其中一部分在对应的一个RLC实体上发送,另一部分在对应的另一个RLC实体上发送。
在该实施例中,可以基于两个RLC实体的缓存状态或信道质量将PDCP PDU动态划分成两部分,例如,可以为缓存PDCP PDU比较多的RLC实体划分小部分数据,为缓存PDCP PDU比较少的RLC实体划分大部分数据。
上述实施例,通过将配置PDCP包复制功能的DRB或SRB的所有PDCP PDU在对应的两个RLC实体上均进行发送,可以提高发送成功率,通过将配置分流功能的DRB或SRB的PDCP PDU划分成两部分,其中一部分在对应的一个RLC实体上发送,另一部分在对应的另一个RLC实体上发送,可以提高发送速度和单位时间内成功发送的PDU数量。
图8是根据一示例性实施例示出的另一种功能配置装置的框图,如图8所示,在上述图7所示实施例的基础上,该功能配置装置还可以包括:重传模块65。
重传模块65被配置为在第一发送模块63将配置PDCP包复制功能的DRB或SRB的所有PDCP PDU在对应的两个RLC实体上均进行发送之后,针对配置PDCP包复制功能且对应的两个RLC实体采用RLC UM模式的DRB或SRB,对未成功发送的PDCP PDU进行重传。
在一个实施例中,重传模块65可以被配置为若在当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,第一预设时长可以由RRC层配置。
在该实施例中,重传模块65可以采用以下一种或多种实现方式重传PDCP PDU:
第一种实现方式:基站在接收UE发送的PDCP PDU后,可以按照预设时间间隔向UE发送PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
第二种实现方式:基站每接收UE发送的一个PDCP PDU,就向UE发送该PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
第三种实现方式:UE在生成某个PDCP PDU例如当前PDCP PDU时,若满足预定条件,则在当前PDCP PDU中添加轮询(polling)指示,并向基站发送当前PDCP PDU。基站接收到包含轮询指示的当前PDCP PDU后,根据该轮询指示向UE发送包含轮询指示的PDCP PDU及其之前接收的PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,上述预定条件可以包括但不局限于以下任一项:1)当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和达到第一预设数值;2)当前PDCP PDU及其之前发送的PDCP PDU的个数达到第二预设数值;3)在发送完当前PDCP PDU之后,发送窗口无法发送新的PDCP PDU;4)在发送完当前PDCP PDU之后,没有其他待发送的PDCP PDU。上述第一预设数值和第二预设数值可以由RRC层配置。
例如,UE先向基站发送PDCP PDU1和PDCP PDU2,之后生成PDCP PDU3,其中,若PDCP PDU1、PDCP PDU2和PDCP PDU3这三个PDU的数据部分的字节数达到第一预设数值,则可以在PDCP PDU3中添加轮询指示,并向基站发送PDCP PDU3。基站接收PDCP PDU3后,可以根据该轮询指示向UE发送PDCP PDU1、PDCP PDU2和PDCP PDU3的反馈信息。其中,UE在发送PDCP PDU1之后的第一预设时长内,未接收到基站发送的PDCP PDU1
的反馈信息,则重传PDCP PDU1。
需要说明的是,若第二预定条件为当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和达到第一预设数值,则在当前PDCP PDU中添加轮询指示时,重置当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和。重置当前PDCP PDU及其之前发送的PDCP PDU的数据部分的字节数之和是为了后续生成新的PDCP PDU时,统计之前发送的PDCP PDU和新的PDCP PDU的数据部分的字节数之和是否达到第一预设数值,进而为是否在新的PDCP PDU中添加轮询指示提供依据。类似地,若第二预定条件为当前PDCP PDU及其之前发送的PDCP PDU的个数达到第二预设数值,则在当前PDCP PDU中添加轮询指示时,重置当前PDCP PDU及其之前发送的PDCP PDU的个数。重置当前PDCP PDU及其之前发送的PDCP PDU的个数是为了后续生成新的PDCP PDU时,统计之前发送的PDCP PDU和新的PDCP PDU的个数之和是否达到第二预设数值,进而为是否在新的PDCP PDU中添加轮询指示提供依据。
第四种实现方式:若UE在向基站发送完除当前PDCP PDU之外的其他PDCP PDU超过第二预设时长之后,未接收到该PDCP PDU的反馈信息,则在生成当前PDCP PDU时,在PDCP PDU中添加轮询指示,并向基站发送当前PDCP PDU。基站接收到包含轮询指示的当前PDCP PDU后,根据该轮询指示向UE发送包含轮询指示的PDCP PDU即当前PDCP PDU及其之前接收的PDCP PDU的反馈信息。对于UE而言,若在一个PDCP PDU例如当前PDCP PDU发送之后的第一预设时长内,未接收到基站发送的当前PDCP PDU的反馈信息或者接收到基站发送的表示未成功接收当前PDCP PDU的反馈信息,则重传当前PDCP PDU。
其中,第二预设时长可以由RRC层配置。
例如,UE在向基站发送完PDCP PDU1超过第二预设时长之后,未接收到该PDCP PDU1的反馈信息,则在生成PDCP PDU2时,可以在PDCP PDU2中添加轮询指示,并向基站发送PDCP PDU2。基站接收PDCP PDU2后,可以根据该轮询指示向UE发送PDCP PDU1和PDCP PDU2的反馈信息。若UE在发送PDCP PDU2之后的第一预设时长内,接收到PDCP PDU2的反馈信息但PDCP PDU2的反馈信息指示基站未接收到PDCP PDU2,则重传PDCP PDU2。
在另一个实施例中,重传模块65可以若接收到的反馈信息中指示有基站未成功接收的PDCP PDU,则重传基站未成功接收的PDCP PDU。
在该实施例中,基站在重排序定时器超时后,向UE发送接收窗口内位于触发重排序
定时器的PDCP PDU及其之前的PDCP PDU的反馈信息。若UE接收到的反馈信息中指示有基站未成功接收的PDCP PDU,则重传基站未成功接收的PDCP PDU。
例如,UE依次向基站发送PDCP PDU1、PDCP PDU2、PDCP PDU3、PDCP PDU4和PDCP PDU5,若基站在接收窗口内依次接收到PDCP PDU1、PDCP PDU2和PDCP PDU5,当接收到PDCP PDU5时,触发重排序定时器,即PDCP PDU5为触发重排序定时器的PDCP PDU,基站可以向UE发送PDCP PDU5及其之前的PDCP PDU的反馈信息,也即PDCP PDU1、PDCP PDU2、PDCP PDU3、PDCP PDU4和PDCP PDU5的反馈信息,其中,PDCP PDU3的反馈信息指示基站未成功接收PDCP PDU3,PDCP PDU4的反馈信息指示基站未成功接收PDCP PDU4,则UE向基站重传PDCP PDU3和PDCP PDU4。
由此可见,上述实施例,可以通过多种方式对未成功发送的PDCP PDU进行重传,实现方式灵活多样。
上述实施例,针对配置PDCP包复制功能且对应的两个RLC实体采用RLC UM模式的DRB或SRB,对未成功发送的PDCP PDU进行重传,可以实现对传输失败的数据进行重传,从而保证开启PDCP包复制功能的业务的可靠性。
