Abstract

Description

数据处理方法、终端设备和网络设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及一种数据处理方法、终端设备和网络设备。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,数据一般基于Turbo码进行编码。在基于Turbo码编码的过程中,受到编码器结构的制约,每个码块的最大比特数为6144,当待编码数据的比特数大于6144时,需要对待编码数据进行码块分割,得到
Figure PCTCN2016106917-appb-000001
个码块,其中L为待编码数据的比特数,该待编码数据一般包括24比特的循环冗余校验(Cyclic Redundancy Check,CRC)信息。
未来的通信系统对数据的解调、反馈具有更高的要求,以5G系统(或称5G NR(new radio)系统)为例,该系统支持超高可靠性与超低时延通信(Ultra Reliable Low Latency Communication,URLLC),URLLC一般要求接收端能够实现数据的快速解调和反馈,在极端情况下,URLLC要求当前时间单元(一个时间单元例如可以是一个子帧)内传输的数据需要在该当前时间单元内进行反馈,即接收端需要在当前时间单元内发送同一时间单元内传输的数据的ACK/NACK信息。
为了支持未来通信系统对数据的解调和反馈的更高要求,终端设备厂商采用了各种措施提高终端设备内部的编码和译码性能,例如,终端设备厂商会在终端设备内部设置并行编码器(或并行译码器),对待编码(或待译码)数据进行并行处理,从而降低编码(译码)时延。
现有LTE系统采用单一的码块分割方式,这种码块分割方式无法充分发挥终端设备的编解码性能,降低了编解码过程的灵活性。

为了提高编解码过程的灵活性,本发明实施例提供的终端设备并非采用固定不变的码块分割方式对当前数据进行码块分割,而是基于网络设备发送的第一指示信息对当前数据进行码块分割,下面结合图1对本发明实施例进行详细描述。
图1是本发明实施例的数据处理方法的示意性流程图。图1的方法包括:
110、终端设备接收网络设备发送的用于码块分割的第一指示信息;
120、所述终端设备根据所述第一指示信息,对所述当前数据进行码块分割,得到至少一个码块,所述当前数据是所述终端设备从所述网络设备接 收到的数据,或者所述当前数据是所述终端设备准备发送至所述网络设备的数据;
130、所述终端设备对所述至少一个码块进行编码或译码。
本发明实施例中,网络设备向终端设备发送用于码块分割的第一指示信息,终端设备可以在第一指示信息的指示下对当前数据进行码块分割,并非像现有技术那样采用固定不变的码块分割方对当前数据进行码块分割式,提高了编解码过程的灵活性。
例如,网络设备可以基于终端设备的编解码性能,指示该终端设备将当前数据分割成与该终端设备的编解码性能匹配的码块数量,或者网络设备可以基于终端设备的编解码性能,指示该终端设备使用与该终端设备的编解码性能匹配的码块分割方式对当前数据进行码块分割,终端设备的编解码性能例如可以是终端设备支持的并行编码器和/或并行译码器的数量。
为了让网络设备更好地指导终端设备对当前数据进行码块分割,终端设备可以向网络设备发送能力信息,以指示终端设备支持的编解码性能,如终端设备支持的并行编码器和/或并行译码器的数量。
进一步地,在一些实施例中,所述第一指示信息可以是所述网络设备基于终端设备的编解码性能,如终端设备支持的并行编码器和/或并行译码器的数量确定的。例如,网络设备通过能力信息获知终端设备具有5个可以并行工作的编码器,该网络设备可以通过第一指示信息指示终端设备将当前数据分成5个码块,以充分利用终端设备的并行编码能力。
需要说明的是,本发明实施例对网络设备向终端设备发送第一指示信息的方式不作具体限定,可以采用动态调度的方式发送第一指示信息,也可以采用半静态的方式发送第一指示信息。以动态调度的方式为例,步骤110可包括:所述终端设备接收网络设备发送的下行控制信令,所述下行控制信令包括所述第一指示信息;以半静态的方式为例,步骤110可包括:所述终端设备接收网络设备发送的高层信令,所述高层信令包括所述第一指示信息
还需要说明的是,本发明实施例中的当前数据可以是共享信道中的数据,具体地,可以是物理共享数据信道,例如,可以是物理下行共享信道(Physical Downlink Shared Channel,PDSCH),也可以是物理上行共享信道(Physical Uplink Shared Channel,PUSCH)。
还需要说明的是,本发明实施例对当前数据分割成的码块的编码方式不 作具体限定。在一些实施例中,终端设备可以采用固定的编码方式进行编码或译码。
在另一些实施例中,终端设备可以基于网络设备指示的编码方式进行编码或译码。具体地,在一些实施例中,图1的方法还可包括:所述终端设备接收所述网络设备发送的第二指示信息,所述第二指示信息用于指示所述当前数据分割成的码块的编码方式;步骤130可包括:所述终端设备根据所述第二指示信息指示的编码方式,对所述至少一个码块进行编码或译码。
进一步地,当前数据分割成的码块的编码方式包括以下编码方式中的至少一种:低密度奇偶校验码(Low Density Parity Check Code,LDPC),Polar码,Turbo码,咬尾卷积码(Tail-Biting Convolutional Coding,TBCC),里德穆勒(Reed Muller,RM)码。
需要说明的是,第一指示信息可用于终端设备对当前数据进行码块分割,但本发明实施例对第一指示信息的具体类型,以及第一指示信息对当前数据的码块分割的指示方式不作具体限定,具体地,第一指示信息可以指示以下信息中的至少一种:所述终端设备将所述当前数据分割成预设的码块数量中的目标码块数量;所述终端设备使用预设的码块分割方式中的目标码块分割方式对所述当前数据进行码块分割;所述终端设备对所述当前数据进行码块分割时所使用的目标码块分割方式的参数的当前取值。
在一些实施例中,第一指示信息指示以上信息中的一种信息。在另一些实施例中,第一指示信息指示以上信息中的多种信息。
需要说明的是,本发明实施例对第一指示信息指示以上信息中的多种信息的方式不作具体限定,例如,可以将用于承载第一指示信息的字段的多种取值划分成不同的取值集合,不同的取值集合可以指示以上信息中的不同信息;又如,用于承载第一指示信息的字段的一个取值可以对应以上信息中的至少两种信息。下面结合具体的实施例进行详细描述。
可选地,在一些实施例中,所述第一指示信息可用于指示所述终端设备将所述当前数据分割成预设的码块数量中的目标码块数量。进一步地,在一些实施例中,目标码块数量可以是基于终端设备的编解码性能,例如可以是终端设备支持的并行编码器和/或并行译码器的数量确定的。应理解,预设的多种码块数量可以由协议约定,也可以由网络设备配置。
进一步地,在本发明实施例中,步骤120可包括:所述终端设备确定用 于承载所述第一指示信息的字段的当前取值;所述终端设备从所述预设的码块数量中选取与所述字段的当前取值对应的码块数量,作为所述目标码块数量;所述终端设备根据所述目标码块数量,对所述当前数据进行码块分割。
以下行控制信令通过3比特的字段(即下表1中的{b0,b1,b2})携带第一指示信息为例,如表1所示,其中Ni为正整数,其取值可以由协议约定或由网络设备预先配置。假设{b0,b1,b2}的取值为{0,0,1}时,对应的N2取值为2,则表示当前数据需要被分割成2个码块。
表1
b0,b1,b2 预设的码块数量
0,0,0 N1
0,0,1 N2
0,1,0 N3
0,1,1 N4
1,0,0 N5
1,0,1 N6
1,1,0 N7
1,1,1 N8
可选地,在一些实施例中,所述第一指示信息可用于指示所述终端设备使用预设的码块分割方式中的目标码块分割方式对所述当前数据进行码块分割。
应理解,预设的码块分割方式可以由协议约定,也可以由网络设备配置。
需要说明的是,本文中的码块分割方式可用于指示当前数据需要被分割成的码块数量的确定方式。
需要说明的是,本文中的码块分割方式也可称为码块分割算法,码块分割算法可用于计算当前数据需要被分割成的码块数量。
进一步地,在本发明实施例中,步骤120可包括:所述终端设备确定用于承载所述第一指示信息的字段的当前取值;所述终端设备从所述预设的码块分割方式中选取与所述字段的当前取值对应的码块分割方式,作为所述目标码块分割方式;所述终端设备根据所述目标码块分割方式,对所述当前数据进行码块分割。
在一些实施例中,目标码块分割方式可以是基于终端设备的编解码性能, 例如可以是终端设备支持的并行编码器和/或并行译码器的数量确定的。
需要说明的是,本发明实施例对预设的码块分割方式的数量,以及预设的码块分割方式的形式不作具体限定,例如,下行控制信令通过1比特(即{b0})承载第一指示信息,如表2所示,b0=0对应码块分割方式A,b0=1对应码块分割方式B。
表2
b0 码块分割方式
0 码块分割方式A
1 码块分割方式B
进一步地,预设的码块分割方式可以包括以下码块分割方式中的至少一种:
码块分割方式一:
Figure PCTCN2016106917-appb-000010
其中NCB表示所述当前数据需要被分割成的码块数量,L表示所述当前数据的长度,Lmax表示所述当前数据被划分成的码块的最大码长,NCB、L、Lmax均为大于或等于1的整数。需要说明的是,Lmax可以由协议约定,也可以由网络设备配置。
码块分割方式二:
Figure PCTCN2016106917-appb-000011
其中NCB表示所述当前数据需要被分割成的码块数量,L表示所述当前数据的长度,Lmin表示所述当前数据被划分成的码块的最小码长,NCB、L、Lmin均为大于或等于1的整数。需要说明的是,Lmin可以由协议约定,也可以由网络设备配置。
码块分割方式三:
Figure PCTCN2016106917-appb-000012
其中NCB表示所述当前数据需要被分割成的码块数量,L表示所述当前数据的长度,Lmax表示所述当前数据被划分成的码块的最大码长,Lmin表示所述当前数据被划分成的码块的最小码长,K为大于或等于1的整数,且K小于或等于所述终端设备支持的并行编码器或并行译码器的数量,NCB、L、Lmax、Lmin均为大于或等于1的整数,且Lmax大于Lmin
具体地,码块分割方式三可以按照如下逻辑执行:
若L≤Lmin,则NCB=1;
若Lmin<L<Ndecoder·Lmin,则
Figure PCTCN2016106917-appb-000013
若K·Lmin≤L≤K·Lmax,则NCB=K,每个编码块长度不小于Lmin且不大于Lmax
若L>K·Lmax,则
Figure PCTCN2016106917-appb-000014
每个编码块长度不小于Lmin且不大于Lmax
在一些实施例中,K等于终端设备支持的并行编码器或并行译码器的数量。
本发明实施例在满足最低码长要求的前提下,可以将当前数据分割成尽量小的码块,从而可以更加充分利用终端设备的并行编解码能力,以加快编码或译码速度。
码块分割方式四:
Figure PCTCN2016106917-appb-000015
其中NCB表示所述当前数据需要被分割成的码块数量,L表示所述当前数据的长度,NCB、L、L'max和Lmax均为大于或等于1的整数,且L'max小于Lmax,K为大于或等于1的整数,且K小于或等于所述终端设备支持的并行编码器或并行译码器的数量。在一些实施例中,K等于终端设备支持的并行编码器或并行译码器的数量。
进一步地,在一些实施例中,L'max可表示当前数据被划分成的码块的最大码长的第一取值,Lmax可表示所述当前数据被划分成的码块的最大码长的第二取值。本发明实施例引入了可变长度的最大码长,进一步提高了编解码过程的灵活性。
上文指出,第一指示信息可指示当前数据需要被分割成的码块数量,也可指示当前数据需要使用的码块分割方式,进一步地,在一些实施例中,还可以将上述两种指示方式结合在一起,下面结合表3进行详细描述。
具体地,用于承载所述第一指示信息的字段包括第一取值集合和第二取值集合,在所述字段的当前取值属于第一取值集合的情况下,所述第一指示 信息用于指示所述终端设备将所述当前数据分割成预设的码块数量中的目标码块数量,在所述字段的当前取值属于第二取值集合的情况下,所述第一指示信息用于指示所述终端设备使用预设的码块分割方式中的目标码块分割方式对所述当前数据进行码块分割。
例如,下行控制信令通过3比特({b0,b1,b2})的字段携带第一指示信息,当{b0,b1,b2}的取值为{0,0,0}或{0,0,1}时,第一指示信息可指示码块分割方式,当{b0,b1,b2}的取值为除{0,0,0}和{0,0,1}之外的其他取值时,第一指示信息可指示的当前数据需要被分割成的码块数量。
表3
b0,b1,b2 预设的码块数量
0,0,0 码块分割方式A
0,0,1 码块分割方式B
0,1,0 N1
0,1,1 N2
1,0,0 N3
1,0,1 N4
1,1,0 N5
1,1,1 N6
可选地,在一些实施例中,所述第一指示信息可用于指示所述终端设备对所述当前数据进行码块分割时所使用的目标预设码块分割方式的参数的当前取值。进一步地,在一些实施例中,目标码块分割方式的参数的当前取值可以是基于终端设备的编解码性能,例如可以是终端设备支持的并行编码器和/或并行译码器的数量确定的。
具体地,预设的码块分割方式可以是协议约定的码块分割方式,也可以是网络设备配置的码块分割方式。该预设的码块分割方式例如可以是上文中的码块分割方式一至码块分割方式四中的至少一种。从上述码块分割方式一至码块分割方式四可以看出,每种码块分割方式具有自己对应的一个或多个参数(或称变量),如码块分割方式一的参数为Lmax,码块分割方式二的参数为Lmin,码块分割方式三的参数为Lmax、Lmin和K,码块分割方式四的参数为L'max和Lmax
进一步地,在本发明实施例中,步骤120可包括:所述终端设备确定用 于承载所述第一指示信息的字段的当前取值;所述终端设备从所述目标码块分割方式的参数的多种取值中选取与所述字段的当前取值对应的取值,作为所述目标码块分割方式的参数的当前取值;所述终端设备根据所述目标码块分割方式的参数的当前取值,使用所述目标码块分割方式对所述当前数据进行码块分割。
具体地,以上文中的码块分割方式一为例,假设下行控制信令通过2比特的字段携带上述第一指示信息,该2比特的取值与码块分割方式一中的参数Lmax的取值(Lmax可以由协议约定,也可以由网络设备配置)的对应关系如表4所示:
表4
b0,b1 Lmax的取值
0,0 Lmax,0
0,1 Lmax,1
1,0 Lmax,2
1,1 Lmax,3
假设{b0,b1}的取值为{0,1},则
Figure PCTCN2016106917-appb-000016
中的Lmax的取值为Lmax,1,终端设备可以基于
Figure PCTCN2016106917-appb-000017
对当前数据进行码块分割,即先基于
Figure PCTCN2016106917-appb-000018
确定NCB,然后将当前数据分割成NCB个码块。
可选地,在一些实施例中,所述第一指示信息指示所述终端设备使用预设的码块分割方式中的目标码块分割方式对所述当前数据进行码块分割,且所述第一指示信息指示所述目标码块分割方式的参数的当前取值。进一步地,在一些实施例中,目标码块分割方式以及目标码块分割方式的参数的当前取值可以是基于终端设备的编解码性能,例如可以是终端设备支持的并行编码器和/或并行译码器的数量确定的。
换句话说,本发明实施例中,终端设备使用的码块分割方式,以及码块分割方式的参数的取值均由网络设备通过第一指示信息指示,进一步提高了编解码过程的灵活性。
本发明实施例对预设的码块分割方式不作具体限定,例如可以包括上文中描述的码块分割方式一至码块分割方式四中的至少一种,不同的码块分割方式的参数可以相同也可以不同。
具体地,步骤120可包括:所述终端设备确定用于承载所述第一指示信 息的字段的当前取值;所述终端设备从所述预设的码块分割方式中选取与所述字段的当前取值对应的码块分割方式,作为所述目标码块分割方式;所述终端设备从所述目标码块分割方式的多种取值中选取与所述字段的当前取值对应的取值,作为所述目标码块分割方式的参数的当前取值;所述终端设备根据所述目标码块分割方式中的参数的当前取值,使用所述目标码块分割方式对所述当前数据进行码块分割。
以下行控制信令通过3比特({b0,b1,b2})的字段携带上述第一指示信息为例,则第一指示信息的取值、预设的码块分割方式以及预设的码块分割方式中的参数的取值的对应关系可以如表5所示。
表5
b0,b1,b2 码块分割方式及码块分割方式的参数的取值
0,0,0 码块分割方式一,Lmax,0
0,0,1 码块分割方式一,Lmax,1
0,1,0 码块分割方式一,Lmax,2
0,1,1 码块分割方式一,Lmax,3
1,0,0 码块分割方式二,Lmin,0
1,0,1 码块分割方式二,Lmin,1
1,1,0 码块分割方式二,Lmin,2
1,1,1 码块分割方式二,Lmin,3
假设终端设备接收到的{b0,b1,b2}的取值为{0,1,1},则终端设备采用码块分割方式一进行码块分割,且码块分割方式一的参数的取值为Lmax,3
可选地,在一些实施例中,所述终端设备对所述当前数据进行码块分割的码块分割方式为以下码块分割方式中的一种:
