Abstract
一种数据传输方法,包括:接收基站发送的第一信息;创建承载分离;向基站传输包含第一逻辑信道和第二逻辑信道的缓存信息的缓存状态报告,接收基站返回的第二信息;获取第一信息和/或第二信息中的约束信息,根据约束信息生成约束关系,其中,约束关系用于限定第一逻辑信道和第二逻辑信道分别映射到不同载波;根据分配信息和约束关系,为第一逻辑信道和第二逻辑信道分别分配不同载波的资源。根据本公开的实施例,由于未绑定逻辑信道和为其分配资源的载波,只是限定了通过不同的载波为第一逻辑信道和第二逻辑信道分配资源,因此当检测到某个载波存在拥塞或链路等问题时,可以将映射到该载波上的逻辑信道调整为映射到其他载波上。
Description
本公开涉及通信技术领域,尤其涉及一种数据传输方法、数据传输装置、数据接收方法、数据接收装置和电子设备。
目前,为了解决数据包和信令包传输的可靠性问题,主要采用在用户设备侧对PDCP(packet data convergence protocol,数据包汇聚协议)层的数据包和信令包进行复制的方案。但由于PDCP层位于无线用设备侧的协议栈的最上层,PDCP层的复制包无法保证能够在底层通过两个载波来发送,这就可能导致同一个载波上的信号质量如果很差,而复制包如果仍然在该载波上发送,那么其发送成功的概率将会很低。
为了解决该问题,提出了PDCP层的复制包与载波结合的方法,也即通过建立split bear(承载分离),将一个PDCP层映射到不同的逻辑信道上,进而映射到不同的载波上发送至基站。
该方案存在的一个问题是,由于将逻辑信道和其所映射到的载波进行了绑定,如果与逻辑信道绑定的载波出现拥塞或链路问题,那么该逻辑信道将无法传输数据。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
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公开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、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种数据传输方法的示意流程图,该方法可以应用于用户设备,例如手机、平板电脑等。如图1所示,该方法包括以下步骤。
S1,接收基站发送的第一信息,所述第一信息包括配置信息。
在一个实施例中,上述基站可以是用户设备对应的同一个cell group(小区群
组)的任一小区所对应的基站,例如一个小区群组中的主小区或副小区所对应的基站。
S2,根据所述配置信息创建第一RLC(Radio Link Control,无线链路层控制协议)实体和第二RLC实体,其中,所述第一RLC实体对应第一逻辑信道,所述第二RLC实体对应第二逻辑信道。
在一个实施例中,可以通过将第一RLC实体标记为与第一逻辑信道相关联,以及将第二RLC实体标记为与第二逻辑信道相关联,使得第一RLC实体对应第一逻辑信道,以及第二RLC实体对应第二逻辑信道。
S3,对PDCP包复制作为复制包,将所述PDCP包通过所述第一RLC实体映射至所述第一逻辑信道,将所述复制包通过所述第二RLC实体映射至所述第二逻辑信道。
在一个实施例中,PDCP包可以包括PDCP层的数据包,还可以包括PDCP层的信令包。若既包括数据包,又包括信令包,那么步骤S3则对数据包和信令包分别进行复制,上述复制包则可以包含这个过程中复制得到的两个包。
图2是根据一示例性实施例示出的一种承载分离的示意图。
如图2所示,可以通过步骤S2,在RLC层中创建第一RLC实体和第二RLC实体,并配置第一RLC实体对应第一逻辑信道,以及第二RLC实体对应第二逻辑信道;然后通过步骤S4,将PDCP层的数据包和/或信令包,复制为复制包,然后通过第一RLC实体将数据包和/或信令包映射至第一逻辑信道,通过第二RLC实体将复制包映射至第二逻辑信道。从而创建承载分离,也即split bear。
S4,向所述基站传输包含所述第一逻辑信道和所述第二逻辑信道的缓存信息的缓存状态报告,接收所述基站返回的第二信息,其中,所述第二信息包括根据所述缓存状态报告生成的载波资源的分配信息。
在一个实施例中,缓存状态报告(buffer status report,BSR)中,除了可以包含第一逻辑信道和第二逻辑信道的缓存信息,还可以包含其他逻辑信道的缓存信息。根据缓存状态报告,基站可以为当前可用的载波分配上行资源,以使载波能够满足第一逻辑信道或第二逻辑信道映射到其上之后能够有足够的资源来承载待传输的数据(包括PDCP包和复制包,还可以包括其他数据)。
S5,获取所述第一信息和/或所述第二信息中的约束信息,根据所述约束信息生成约束关系,其中,所述约束关系用于限定所述第一逻辑信道和所述第二逻辑信道
分别映射到不同载波。
在一个实施例中,第一信息除了可以包括配置信息,还可以包括约束信息,约束信息可以独立于配置信息,也可以包含于配置信息,例如可以包含于配置信息中的承载配置信息,也可以包含于配置信息中的MAC层配置信息。和/或第二信息除了可以包括分配信息,还可以包括约束信息,约束信息可以独立于分配信息,也可以包含于分配信息。
在一个实施例中,在第一信息包含约束信息,而第二信息不包含约束信息的情况下,基站可以在步骤S1中向用户设备发送的第一信息中,携带用于限定不同逻辑信道映射到不同载波的约束信息,还可以携带用于指示承载如何配置,指示MAC层如何配置的配置信息,例如指示其他逻辑信道关联的RLC实体;而在步骤S4中向用户设备发送的第二信息,则携带用于指示用户设备载波上行资源的分配结果的分配信息,例如分配信息可以包括UL grant(上行授权,也可以称为上行授予),用于指示载波中的哪些时隙用于传输所述用户设备的上行数据。
在这种情况下,上述约束信息可以包含于配置信息的承载配置信息中,还可以位于配置信息的MAC层配置信息中。
例如约束信息包含于承载配置信息中,那么用户设备可以通过对承载进行配置,来根据约束关系配置第一逻辑信道和第二逻辑信道。在这种情况下,可以按照图1所示的执行顺序,在步骤S4和步骤S6之间执行步骤S5,也可以根据需要调整步骤S5的执行顺序,只需要保证步骤S5在步骤S2和步骤S6之间执行即可。
例如约束信息包含于MAC层配置信息中,那么用户设备可以在根据MAC层配置信息通过MAC层为逻辑信道分配载波上的资源之前,生成第一逻辑信道和第二逻辑信道的约束关系。在这种情况下,按照图1所示的执行顺序在步骤S4和步骤S6之间执行步骤S5。
在一个实施例中,在第二信息包含约束信息,而第一信息不包含约束信息的情况下,基站可以在步骤S4中向用户设备发送的第二信息中,携带用于限定不同逻辑信道映射到不同载波的约束信息,还可以携带用于指示用户设备载波上行资源的分配结果的分配信息,例如分配信息可以包括UL grant,用于指示载波中的哪些时隙用于传输所述用户设备的上行数据;而在步骤S1中向用户设备发送的配置信息,则用于指示承载如何配置,指示MAC层如何配置。
在一个实施例中,在第一信息包含约束信息,第二信息也包含约束信息的情况下,第一信息和第二信息可以分别包含完整的约束信息,那么用户设备可以根据第一信息中的约束信息来生成约束关系,也可以根据第二信息中的约束信息生成约束关系;第一信息可以包含第一部分约束信息,第二信息可以包含第二部分约束信息,那么用户设备可以根据第一部分约束信息和第二部分约束信息生成约束关系。
S6,根据所述分配信息和所述约束关系,为所述第一逻辑信道和所述第二逻辑信道分别分配不同载波的资源,以通过所述不同的载波分别将所述PDCP包和所述复制包传输至所述基站。
在一个实施例中,约束关系可以包含对应第一逻辑信道的第一标识,以及对应第二逻辑信道的第二标识,MAC层在为第一逻辑信道分配载波的资源时,可以根据第二标识确定第二逻辑信道,然后查询是否已为第二逻辑信道分配了该载波的资源,若未为第二逻辑信道分配该载波的资源,则为第一逻辑信道分配该载波的资源,为第二逻辑信道分配其他载波的资源;若已为第二逻辑信道分配了该载波的资源,则为第一逻辑信道分配其他载波的资源。
在一个实施例中,约束关系可以包含互斥逻辑信息,MAC层在为逻辑信道分配载波上的资源时,若识别到互斥逻辑信息,则为每个逻辑信道分别分配不同的载波的资源。
在一个实施例中,根据约束关系,可以为第一逻辑信道和第二逻辑信道分配不同载波的资源,根据分配信息,可以确定载波中的哪些资源,例如时隙资源,用于传输所述用户设备的上行数据,从而确定PDCP包和复制包在不同载波上分别对应的资源,进而进行传输。
由于本实施例中并未绑定逻辑信道和为其分配资源的载波,只是限定了通过不同的载波为第一逻辑信道和第二逻辑信道分配资源,因此当检测到某个载波存在拥塞或链路等问题时,可以将映射到该载波上的逻辑信道调整为映射到其他载波上,以保证顺利地传输数据。
例如对于3个载波A、B、C,在某次用户设备向基站传输PDCP包和复制包时,将第一逻辑信道映射到A载波,将第二逻辑信道映射到B载波;而在下一次用户设备向基站传输PDCP包和复制包时,若检测到A载波存在拥塞或链路等问题,那么可以将第一逻辑信道映射到C载波,将第二逻辑信道映射到B载波,也即仍然能够顺利地
通过第一逻辑信道将PDCP包以及通过第二逻辑信道将PDCP复制包传输至基站。
图3是根据一示例性实施例示出的另一种数据传输方法的示意流程图。如3所示,在图1所示实施例的基础上,所述为所述第一逻辑信道和所述第二逻辑信道分别分配不同载波的资源包括:
步骤S61,在为所述第一逻辑信道分配第一载波的资源时,确定是否已为所述第二逻辑信道分配了所述第一载波的资源,若已为所述第二逻辑信道分配所述第一载波的资源,执行步骤S62;若未为所述第二逻辑信道分配所述第一载波的资源,执行步骤S63;
步骤S62,为所述第一逻辑信道分配第二载波的资源;
步骤S63,为所述第一逻辑信道分配所述第一载波的资源,为所述第二逻辑信道分配所述第二载波的资源。
在一个实施例中,在为第一逻辑信道分配第一载波的资源时,若检测到已经在第一载波上为第二逻辑信道分配了资源,那么为了保证为第一逻辑信道和第二逻辑信道分配不同的载波的资源,可以通过将异于第一载波的第二载波的资源分配给第一逻辑信道;而若检测到在第一载波上尚未为第二额逻辑信道分配资源,那么可以直接在第一载波上为第一逻辑信道分配资源,然后在第二载波上位第二逻辑信道分配资源。从而保证属于同一个承载分离中的两个RLC实体分别对应的第一逻辑信道和第二逻辑信道分配不同载波的资源。
图4是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如4所示,在图3所示实施例的基础上(未示出图3中的所有步骤),在为所述第一逻辑信道分配了所述第一载波资源,为所述第二逻辑信道分配了所述第二载波资源的情况下,所述方法还包括:
步骤S71,在检测到所述第一载波不可用时,确定是否存在可用的其他载波,若存在所述其他载波,执行步骤S72;
步骤S72,为所述第一逻辑信道分配所述其他载波的资源;和/或
步骤S81,在检测到所述第二载波不可用时,确定是否存在可用的其他载波,若存在所述其他载波,执行步骤S82;
步骤S82,为所述第二逻辑信道分配所述其他载波的资源。
在一个实施例中,载波不可用,可以指载波存在拥塞、链路问题等因素。
在一个实施例中,由于第一逻辑信道和第一载波并未绑定,因此在检测到第一载波不可用时,可以查询可用的其他载波,然后为第一逻辑信道分配其他载波的资源,以保证PDCP包可以通过第一逻辑信道在其他载波上顺利地传输至基站。
在一个实施例中,由于第二逻辑信道和第二载波并未绑定,因此在检测到第二载波不可用时,可以查询可用的其他载波,然后为第二逻辑信道分配其他载波的资源,以保证复制包可以通过第二逻辑信道在其他载波上顺利地传输至基站。
图5是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如5所示,在图4所示实施例的基础上,在为所述第一逻辑信道分配了所述第一载波资源,为所述第二逻辑信道分配了所述第二载波资源的情况下,所述方法还包括:
步骤S71,在检测到所述第一载波不可用时,且不存在所述其他载波,执行步骤S73;
步骤S73,为所述第一逻辑信道分配所述第二载波的资源;和/或
步骤S81,在检测到所述第二载波不可用时,且不存在所述其他载波,执行步骤S83;
步骤S83,为所述第二逻辑信道分配所述第一载波的资源。
在一个实施例中,在为第一逻辑信道分配了第一载波资源,为第二逻辑信道分配了第二载波资源后,由于载波可能出现拥塞、链路问题等情况而导致不可用,那么在不存在可用的其他载波的情况下,可以为两个信道分配同一个可用的载波的资源,也即在第一载波不可用的情况下,为第一逻辑信道分配第二载波的资源,在第二载波不可用的情况下,为第二逻辑信道分配第一载波的资源,以保证两个逻辑信道上的数据都可以传输至基站,从而顺利完成通信。
图6是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如图6所示,在图5所示实施例的基础上,上述方法还包括:
步骤S74,在检测到所述第一载波不可用,且不存在所述其他载波的情况下,确定已为所述第二逻辑信道分配了所述第二载波的资源的时长是否大于第一预设时长,若大于第一预设时长,执行步骤S72;
步骤S73,为所述第一逻辑信道分配所述第二载波的资源;和/或
步骤S84,在检测到所述第二载波不可用,且不存在所述其他载波的情况下,确定已为所述第一逻辑信道分配了所述第一载波的资源的时长是否大于第二预设时长,若大于第二预设时长,执行步骤S82;
步骤S85,为所述第二逻辑信道分配所述第二载波的资源。
在一个实施例中,在检测到所述第一载波不可用,且不存在所述其他载波的情况下,可以进一步确定为第二逻辑信道分配了第二载波的资源的时长是否大于第一预设时长,在大于第一预设时长的情况下,可以确定复制包已经通过第二逻辑信道在第二载波上传输完毕,以保证在将第二载波的资源分配给第一逻辑信道来传输PDCP包时,不会对复制包的传输造成影响。
在一个实施例中,在检测到所述第二载波不可用,且不存在所述其他载波的情况下,可以进一步确定为第一逻辑信道分配了第一载波的资源的时长是否大于第二预设时长,在大于第二预设时长的情况下,可以确定PDCP包已经通过第一逻辑信道在第一载波上传输完毕,以保证在将第一载波的资源分配给第二逻辑信道来传输复制包时,不会对PDCP包的传输造成影响。
在一个实施例中,可以通过在第一信息中设置一个或多个定时器值,来作为上述第一预设时长和/或第二预设时长。
图7是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如7所示,在图1所示实施例的基础上,所述获取所述第一信息和/或所述第二信息中的约束信息,根据所述约束信息生成约束关系包括:
步骤S51,获取所述第一信息和/或所述第二信息中预设标识信息的值;
步骤S52,确定所述预设标识信息的值是否等于预设值,在所述预设标识信息的值等于预设值的情况下,执行步骤S53;
步骤S53,生成所述约束关系。
在一个实施例中,约束信息可以是上述预设标识信息,例如预设标识信息的值可以为1或0,预设值则可以为1,当预设标识信息的值为1时,那么可以生成约束关系,而在预设标识信息的值为0是,则不生成约束关系。
图8是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如8所示,在图1所示实施例的基础上,所述获取所述第一信息和/或所述第二信息中的约束
信息,根据所述约束信息生成约束关系包括:
步骤S54,确定所述第一信息和/或所述第二信息中是否包含与所述第一逻辑信道相关联的身份标识,其中,所述身份标识用于标记与所述第一逻辑信道映射到不同载波的第二逻辑信道,在存在所述身份标识的情况下,执行步骤S55;
步骤S55,根据所述身份标识确定所述第二逻辑信道;
步骤S53,生成所述约束关系。
在一个实施例中,约束信息可以是与第一逻辑信道相关联的身份标识,根据该身份标识信息,用户设备可以确定第二额逻辑信道,进而生成第一逻辑信道和第二逻辑信道的约束关系。
图9是根据一示例性实施例示出的又一种数据传输方法的示意流程图。如9所示,在图1所示实施例的基础上,所述获取所述第一信息和/或所述第二信息中的约束信息,根据所述约束信息生成约束关系包括:
步骤S56,确定所述第一信息和/或所述第二信息标记的需要分配不同载波的资源的多个逻辑信道组;
步骤S57,确定所述第一逻辑信道和所述第二逻辑信道是否分别属于所述多个逻辑信道组中的不同逻辑信道组,若所述第一逻辑信道和所述第二逻辑信道分别属于所述多个逻辑信道组中的不同逻辑信道组,执行步骤S53;
步骤S53,生成所述约束关系。
在一个实施例中,约束信息可以是标记的需要分配不同载波的资源的多个逻辑信道组,根据该约束信息,可以进一步确定承载分离中的第一逻辑信道和第二逻辑信道是否属于不同的逻辑信道组,若属于不同的逻辑信道组,则可以生成约束关系,若属于同一个逻辑信道组,那么则不生成约束关系。
图10是根据一示例性实施例示出的一种数据接收方法的示意流程图,该方法可以适用于基站。如图10所示,该数据接收方法包括以下步骤。
步骤S101,向用户设备传输第一信息,所述第一信息包括配置信息;
步骤S102,接收所述用户设备根据所述配置信息将所述PDCP包通过第一RLC实体映射至所述第一逻辑信道,以及将所述复制包通过第二RLC实体映射至所述第二逻辑信道后,所述第一逻辑到和所述第二逻辑信道的缓存状态报告;

在一个实施例中,上述基站可以是用户设备对应的同一个cell group(小区群组)的任一小区所对应的基站,例如一个小区群组中的主小区或副小区所对应的基站。
