Description

一种数据处理方法、装置及设备
本申请要求在2020年4月14日提交中国专利局、申请号为202010291987.2、申请名称为“一种数据处理方法、装置及设备”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,尤其涉及一种数据处理方法、装置及设备。
背景技术
在通信系统中,由于无线信道存在信号衰落的问题,无线信号的接收端可能无法对接收到的信息进行正确译码,从而无法获取准确的信息。混合自动重传请求(hybrid automatic repeat request,HARQ)技术是一种将前向纠错编码(forward error correction,FEC)和自动重传请求(automatic repeat request,ARQ)相结合的技术。传统的HARQ的工作原理为:当接收端无法对接收到的信息进行正确译码时,接收端会保留接收到的数据,并要求发送端重新发送之前传输的信息。接收端收到重传的信息后,将重传的信息和之前接收到的信息进行合并后再译码。可见,接收端要正确译码出发送端发出的所有比特,可能需要进行多次重传。但是传统的HARQ在多次重传时,传输效率较低。
发明内容
本申请实施例提供一种数据处理方法、装置及设备,该数据处理方法使得只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,就能实现接近于信道容量的传输。
第一方面,本申请实施例提供一种数据处理方法,该方法可以由第一通信设备所执行。其中,第一通信设备可以是编码数据的发送端。第一通信设备可以获取X个信息比特块,其中,一个信息比特块包括K个信息比特,并且一个信息比特块被划分为Q个信息比特子块。其中,一个信息比特子块为长度为K/Q的二进制序列。第一通信设备将每一个信息比特块的Q个信息比特子块按照第一顺序置于M个第一待编码块中的Q个第一待编码块中。其中,第一顺序为每一个信息比特块的第q个信息比特子块位于所在第一待编码块的第(q-1)*K/Q+1至第q*K/Q可靠的位置,q满足1≤q≤Q,M满足M=X+Q-1。第一通信设备对M个第一待编码块分别进行polar码编码,获取M个第一编码块,并且向第二通信设备发送所述M个第一编码块。
当需要重传时,第一通信设备将每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第二待编码块中的Q个第二待编码块中,第二顺序与第一顺序满足映射关系。第一通信设备对M个第二待编码块分别进行polar码编码,获取M个第二编码块,并且向第二通信设备发送M个第二编码块。
可见,第一通信设备向第二通信设备初传M个第一编码块时,M个第一编码块中的多个信息比特子块按照第一顺序排列,有利于第二通信设备正确译码。若第二通信设备译码失败,第一通信设备可以向第二通信设备重传M个第二编码块,M个第二编码块中的多个信息比特子块按照第二顺序排列,且第二顺序与第一顺序满足映射关系,有利于第二 通信设备根据第一编码块和第二编码块正确译码。只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,第一通信设备就能实现接近于信道容量的传输。
在一种可能的设计中,第二顺序为每一个信息比特块的第q个信息比特子块位于所在第二待编码块的第(Q-q)*K/Q+1至第(Q-q+1)*K/Q可靠的位置。可见,对于每一个信息比特块中的信息比特子块而言,第二顺序为第一顺序的反序。第二待编码块中的信息比特子块按照第二顺序排列,有利于第二通信设备正确译码。
在一种可能的设计中,第一顺序和第二顺序满足以下映射关系:
Figure PCTCN2021082192-appb-000001
其中,a q为任意一个信息比特块的Q个信息比特子块中的任意一个信息比特子块,A t为任意一个信息比特子块映射后对应的信息比特子块,F为polar码的生成矩阵,J为正整数且满足K/Q=2 J,P为正整数且满足2 P-1≤Q≤2 P,t满足1≤t≤2 P
可见,对于每一个信息比特块中的信息比特子块的排序,第二顺序为第一顺序按照映射关系映射得到的。其中,该映射关系可以是第一顺序按照polar码的生成矩阵映射得到,有利于第二通信设备正确译码。
在一种可能的设计中,当需要重传时,第一通信设备将每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第三待编码块中的Q个第三待编码块中。其中,第三待编码块采用的第二顺序与第二待编码块采用的第二顺序不同。第一通信设备对M个第三待编码块分别进行polar码编码,获取M个第三编码块,并且向第二通信设备发送M个第三编码块。
可见,第一通信设备再次重传M个第三编码块时,M个第三编码块中的多个信息比特子块也可以按照第二顺序排列,有利于第二通信设备根据第一编码块、第二编码块和第三编码块正确译码。
在一种可能的设计中,当需要重传时,第一通信设备将每一个信息比特块的Q个信息比特子块从二进制域映射至2 w进制域,获取映射后的任意一个信息比特块为

其中,
Figure PCTCN2021082192-appb-000003
为映射后的任意一个信息比特块中的任意一个信息比特子块,
Figure PCTCN2021082192-appb-000004
为长度为K/wQ的2 w进制序列,w为大于1的正整数;
第一通信设备将每一个映射后的信息比特块的Q个信息比特子块进行转换,其中,任意一个映射后的信息比特块的Q个信息比特子块与转换后对应的Q个信息比特子块之间满足以下关系:
Figure PCTCN2021082192-appb-000005
其中,
Figure PCTCN2021082192-appb-000006
Figure PCTCN2021082192-appb-000007
转换后对应的信息比特子块,H n为在2 w进制域上的K/w×K/w的通用解码矩阵UDM,n用于指示第n次传输;n满足n∈[1,2,...,N],N为第一通信设备传输的总次数,且N为大于3的正整数;
第一通信设备将
Figure PCTCN2021082192-appb-000008
进行反映射,获取
Figure PCTCN2021082192-appb-000009
反映射后对应的信息比特块为[A n,1,A n,2,...,A n,Q];其中,A n,Q为长度为K/Q的二进制序列;
第一通信设备将反映射后的任意一个信息比特块的Q个信息比特子块按照第一顺序置于M个第n待编码块中。
第一通信设备对M个第n待编码块分别进行polar码编码,获取M个第n编码块,并且向第二通信设备发送M个第n编码块。
可见,当第一通信设备的传输次数超过三次时,由于三次或三次以上的重传在多进制 域进行,那么第一通信设备需要将M个第n待编码块中的多个信息比特子块进行相应的处理,再对M个第n待编码块进行编码。
在一种可能的设计中,任意一个编码块至少承载一个信息比特子块,至多承载Q个信息比特子块;其中,编码块包括第一编码块和第二编码块。
在一种可能的设计中,每个编码块按照编码块的标识依次排列,其中,第一个编码块承载一个信息比特子块;第一个至第Q个编码块承载的信息比特块的数量按照编码块的排列顺序,依次增加一个,第Q个编码块承载Q个信息比特子块。第Q+1个编码块至第M个编码块承载信息比特子块的数量按照编码块的排列顺序,依次减少一个;第M个编码块承载一个信息比特子块。
可见,在不考虑码率损失的情况下,编码块承载的信息比特子块的数量从1个依次增加至Q个,然后再从Q个依次减少至1个。采用该排列方式可以使M个编码块承载完整的X个信息比特块。
在一种可能的设计中,Q为码率R的量化阶数,Q为正整数。第i个编码块的码率r i=i×R/Q,i满足1≤i≤Q。第j个编码块的码率r j=(M-j+1)×R/Q,j满足Q+1≤j≤M。可见,在不考虑码率损失的情况下,编码块的码率从R/Q逐渐增加至R,然后再从R逐渐降低至R/Q。
第二方面,本申请实施例提供一种数据处理方法,该方法可以由第二通信设备所执行。其中,第二通信设备可以是编码数据的接收端。第二通信设备接收第一通信设备初传的M个第一编码块,该M个第一编码块是M个第一待编码块进行polar码编码得到的。其中,M个第一待编码块承载X个信息比特块,每一个信息比特块被划分为Q个信息比特子块。每一个信息比特块的Q个信息比特子块按照第一顺序置于M个第一待编码块中的Q个第一待编码块中。其中,第一顺序为每一个信息比特块的第q个信息比特子块位于所在第一待编码块的第(q-1)*K/Q+1至第q*K/Q可靠的位置,q满足1≤q≤Q,M满足M=X+Q-1。
第二通信设备再次接收第一通信设备重传的M个第二编码块,该M个第二编码块是M个第二待编码块进行polar码编码得到的。每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第二待编码块中的Q个第二待编码块中,第二顺序与第一顺序满足映射关系。第二通信设备可以将M个第一编码块和M个第二编码块进行合并译码,获取译码数据。
可见,第二通信设备接收第一通信设备初传的M个第一编码块时,M个第一编码块中的多个信息比特子块按照第一顺序排列,有利于第二通信设备正确译码。若第二通信设备译码失败,第二通信设备可以接收第一通信设备重传的M个第二编码块,M个第二编码块中的多个信息比特子块按照第二顺序排列,且第二顺序与第一顺序满足映射关系,有利于第二通信设备根据第一编码块和第二编码块正确译码。
在一种可能的设计中,第二顺序为每一个信息比特块的第q个信息比特子块位于所在第二待编码块的第(Q-q)*K/Q+1至第(Q-q+1)*K/Q可靠的位置。
在一种可能的设计中,第一顺序和第二顺序满足以下映射关系:

其中,a q为任意一个信息比特块的Q个信息比特子块中的任意一个信息比特子块,A t为任意一个信息比特子块映射后对应的信息比特子块,F为polar码的生成矩阵,J为正整数且满足K/Q=2 J,P为正整数且满足2 P-1≤Q≤2 P;t满足1≤t≤2 P
在一种可能的设计中,第二通信设备将M个第一编码块和M个第二编码块进行合并 译码,获取译码数据,包括:
若第一通信设备两次传输的信道容量之和大于或等于码率R,第二通信设备译码获取第一待编码块承载的一个信息比特块包括的k 1个信息比特子块

k 2满足1≤k 2≤Q,k 1+k 2≥Q;
第二通信设备获取该信息比特块包括的Q个信息比特子块为[a 1,a 2,...,a Q]。
可见,若第一通信设备两次传输的信道容量之和大于或等于码率R,由于第一编码块和第二编码块的排列方式按照上述第一顺序和第二顺序,第二通信设备通过两次译码可以实现正确译码。
在一种可能的设计中,若第二通信设备译码失败,第二通信设备接收第一通信设备重传的M个第三编码块,该M个第三编码块是M个第三待编码块进行polar码编码得到的。每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第三待编码块中的Q个第三待编码块中。其中,第三待编码块采用的第二顺序与第二待编码块采用的第二顺序不同。
若第一通信设备两次传输的信道容量之和小于码率R,且第一通信设备三次传输的信道容量之和大于或等于码率R,第二通信设备译码获取第一待编码块承载的一个信息比特块包括的k 1个信息比特子块

第二通信设备根据第一顺序和第二顺序的映射关系,获取k 3个信息比特子块映射前对应的k 3个信息比特子块为

那么,第二通信设备可以获取该信息比特块包括的Q个信息比特子块为[a 1,a 2,...,a Q]。
可见,若第一通信设备两次传输的信道容量之和小于码率R,且第一通信设备三次传输的信道容量之和大于或等于码率R,由于第一编码块、第二编码块以及第三编码块的排列方式按照上述第一顺序和第二顺序,第二通信设备通过三次译码可以实现正确译码。
在一种可能的设计中,若第二通信设备译码失败,第二通信设备接收第一通信设备重传的M个第n编码块,该M个第n编码块是M个第n待编码块进行polar码编码得到的。每一个处理后的信息比特块的Q个信息比特子块按照第一顺序置于M个第n待编码块中的Q个所述第n待编码块中。第二通信设备将M个第一编码块直至M个第n编码块进行合并译码,获取译码数据。其中,对每一个所述信息比特块的处理满足以下条件:

进行反映射后对应的信息比特块满足[A n,1,A n,2,...,A n,Q];其中,A n,Q为长度为K/Q的二进制序列。
可见,若第二通信设备译码失败,第二通信设备可以接收第一通信设备多次重传的编码块。并且当第一通信设备的传输次数超过三次时,由于三次或三次以上的重传在多进制域进行,那么第一通信设备需要将M个第n待编码块中的多个信息比特子块进行相应的处理,再对M个第n待编码块进行编码。
在一种可能的设计中,任意一个编码块至少承载一个信息比特子块,至多承载Q个信息比特子块;其中,编码块包括第一编码块和第二编码块。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。
Polar码是一种能够被严格证明达到信道容量的信道编码方案,polar码具有高性能,低复杂度,匹配方式灵活等特点。目前polar码已经被确定为第五代移动通信(the 5 thgeneration,5G)控制信道增强移动宽带(enhanced mobile broadband,eMBB)场景的上行和/或下行控制信道编码方案。
请参见图1,图1为一种8×8的polar码编码示意图,其中,待编码比特按照各自的可靠度进行排序,依次排列在待编码块中的不同位置。通常来说,可靠度较高的比特被设置为信息比特(data),可靠度较低的比特被设置为固定比特(frozen)。固定比特的值通常设置为0,在实际传输中发送端和接收端都已知。如图1所示,u 7,u 6,u 5,u 3为可靠度靠前的四位比特,分别设置为信息比特;u 4,u 2,u 1,u 0为可靠度靠后的四位比特,分别设置为固定比特。
请参见图2,图2为本申请实施例提供的一种通信系统,该通信系统包括第一通信设备和第二通信设备。其中,第一通信设备为编码数据的发送端,用于向第二通信设备发送下行数据,或者接收来自第二通信设备的上行数据。例如,第一通信设备在向第二通信设备发送下行数据时,可以对待编码的信息比特进行polar码编码,信道编码后的数据经过星座调制后,可以通过下行数据信道发送给第二通信设备。
第二通信设备为编码数据的接收端,用于向第一通信设备发送上行数据,或者接收来自第一通信设备的下行数据。例如,第二通信设备在向第一通信设备发送上行数据时,可以对待编码的信息比特进行polar码编码,信道编码后的数据经过星座调制后,可以通过上行数据信道发送给第一通信设备。
其中,第一通信设备可以是任意一种具有无线收发功能的设备,为覆盖范围内的第二通信设备提供无线通信服务。接入网设备可以包括但不限于:长期演进(long term evolution,LTE)系统中的演进型基站(NodeB或eNB或e-NodeB,evolutional NodeB),新一代无线接入技术(new radio access technology,NR)中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point,TRP),3GPP后续演进的基站,WiFi系统中的接入节点,无线中继节点,无线回传节点,车联网、D2D通信、机器通信中承担基站功能的设备,卫星等。
其中,第二通信设备可以是一种具有无线收发功能的终端设备,或者第二通信设备也可以是一种芯片。所述终端设备可以是用户设备(user equipment,UE)、手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、车载终端设备、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、可穿戴终端设备等。
在图2所示的通信系统中,由于无线信道存在信号衰落的问题,无线信号的接收端可能无法对接收到的信息进行正确译码,从而无法获取准确的信息。混合自动重传请求(hybrid automatic repeat request,HARQ)技术是一种将前向纠错编码(forward error correction,FEC)和自动重传请求(automatic repeat request,ARQ)相结合的技术。传统的HARQ的工作原理为:当接收端无法对接收到的信息进行正确译码时,接收端会保留接收到的数据,并要求发送端重新发送之前传输的信息。接收端收到重传的信息后,将重传的信息和之前接收到的信息进行合并后再译码。
可见,接收端要正确译码出发送端发出的所有比特,可能需要进行多次重传,带来额外的时延。为了解决上述问题,本申请实施例提供一种数据处理方法,该数据处理方法可以由第一通信设备所执行。只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,第一通信设备就能实现接近于信道容量的传输。
下面将结合具体的实施例进行描述。
本申请实施例提供一种数据处理方法,请参见图3。该数据处理方法可以由第一通信 设备和第二通信设备交互执行,包括以下步骤:
S301,第一通信设备获取X个信息比特块,一个信息比特块被划分为Q个信息比特子块;
S302,第一通信设备将每一个信息比特块的Q个信息比特子块按照第一顺序置于M个第一待编码块中的Q个第一待编码块中。
第一通信设备在对多个待编码的信息比特进行处理时,可以将多个待编码的信息比特划分到不同的信息比特块中。其中,一个信息比特块包括多个信息比特。例如,第一通信设备将每K个信息比特划分到一个信息比特块中,即一个信息比特块包括K个信息比特,如图4a所示。
每一个信息比特块可以被划分为Q个信息比特子块,即把K个信息比特划分到Q个信息比特子块,如图4a所示。其中,a q表示任意一个信息比特子块,a q为长度为K/Q的二进制序列,q满足1≤q≤Q。Q代表码率的量化阶数,Q为正整数。例如,如图4b所示的信息比特块和信息比特子块,码率的量化阶数为3,即Q=3。
需要注意的是,若K/Q不是整数,本实施例在确定K/Q时可以最多补充Q-1个填充比特,以确保K/Q为整数。例如,若K=100,Q=3,此时K/Q不为整数。补充2个填充比特后,K/Q=34,即a 1和a 2分别包括34个信息比特;a 3包括32个信息比特(另外两个为填充比特)。后续第一通信设备中的polar码编码器在对信息比特子块进行编码处理时,仅对每一个信息比特子块中的信息比特进行处理,填充比特将不作处理。
第一通信设备获取X个信息比特块后,可以将X个信息比特块置于M个第一待编码块中。其中,待编码块用于承载第一通信设备向第二通信设备传输的待编码数据。可以理解的是,第一待编码块表示第一通信设备第一次向第二通信设备传输时采用的待编码块,第二待编码块表示第一通信设备第二次向第二通信设备传输时采用的待编码块,以此类推。在一种可能的情况下,第一待编码块的数量M满足M=X+Q-1。其中,任意一个第一待编码块至少承载一个信息比特子块,至多承载Q个信息比特子块。
请参见图5a,图5a为本申请实施例提供的一种第一待编码块的示意图。若不考虑码率损失,一种第一待编码块中的信息比特子块的排列方式如图5a所示。例如,图5a中包括3个信息比特块,即X=3;包括5个第一待编码块,即M=5;码率的量化阶数为3,即Q=3。其中,每一个信息比特块都包括Q个信息比特子块。需要注意的是,同一个信息比特块的Q个信息比特子块分别位于不同的Q个第一待编码中,如图5a所示。
其中,每一个第一待编码块依次排列,第一个第一待编码块承载一个信息比特子块;第一个至第Q个第一待编码块承载的信息比特块的数量按照排列顺序,依次增加一个,第Q个第一待编码块承载Q个信息比特子块。第Q+1个至第M个第一待编码块承载信息比特子块的数量按照排列顺序,依次减少一个,第M个第一待编码块承载一个信息比特子块。
例如,图5a中,第一个第一待编码块承载1个信息比特子块,第二个第一待编码块承载2个信息比特子块,第三个第一待编码块承载3个信息比特子块,第四个第一待编码块承载2个信息比特子块,第五个第一待编码块承载1个信息比特子块。
可选的,为了降低码率损失,第一通信设备将信息数据分成X个信息比特块时,可以进行特别的处理。其中,每一个第一待编码块依次排列,第一个第一待编码块承载一个信息比特子块;第一个至第M个第一待编码块承载的信息比特块的数量按照排列顺序,依次增加一个,第Q个至第M个第一待编码块分别承载Q个信息比特子块。
例如,请参见图5b,图5b为本申请实施例提供的另一种第一待编码块的示意图。其 中,图5b中包括6个信息比特块,6个第一待编码块,码率的量化阶数Q=3。第一个至第四个信息比特块分别包括3个信息比特子块。第五个信息比特块包括2个信息比特子块,第六个信息比特块包括1个信息比特子块,即第五个和第六个信息比特块分别进行特别的处理。在图5b中,第一个第一待编码块承载1个信息比特子块,第二个第一待编码块承载2个信息比特子块,第三个至第六个第一待编码块分别承载3个信息比特子块。
又例如,请参见图5c,图5c为本申请实施例提供的另一种第一待编码块的示意图。其中,图5c中包括6个信息比特块,6个第一待编码块,码率的量化阶数Q=2。相较于图5b中的示例,图5c中的码率的量化阶数为2,信息比特块和第一待编码块的数量相同。其中,图5c中的第六个信息比特块采用特别的处理,使得第六个信息比特块仅包括一个信息比特子块。第一通信设备将上述6个信息比特块分别置于6个第一待编码块中,如图5c所示。
再例如,请参见图5d,图5d为本申请实施例提供的另一种第一待编码块的示意图。其中,图5d中包括6个信息比特块,6个第一待编码块,码率的量化阶数Q=4。相较于图5b中的示例,图5d中的码率的量化阶数为4,信息比特块和第一待编码块的数量相同。其中,图5d中的第四个至第六个信息比特块采用特别的处理,使得第四个信息比特块包括3个信息比特子块,第五个信息比特块包括2个信息比特子块,第六个信息比特块包括1个信息比特子块。第一通信设备将上述6个信息比特块分别置于6个第一待编码块中,如图5d所示。
需要注意的是,图5a和图5b所示的第一待编码块为两种基础的第一待编码块,第一待编码块还可以介于上述两种基础的第一待编码块之间。
例如,请参见图5e,图5e为另一种第一待编码块的示意图。其中,M=6表示一共有6个第一待编码块,X=4表示一共传输4个信息比特块。图5e所示的待传输的4个信息比特块均为完整的信息比特块。将上述4个信息比特块置于6个第一待编码块中。其中,第一个和第六个第一待编码块承载1个信息比特子块,第二个和第五个第一待编码块承载2个信息比特子块,第三个和第四个第一待编码块承载3个信息比特子块,如图5e所示。第一待编码块还可以采用其他类似的特别的处理,本实施例不作限定。
其中,任意一个第一待编码块还包括一个或多个固定比特,如图5a中的信息比特块的阴影区域所示。固定比特的值通常设置为0,在实际传输中发送端和接收端都已知。
需要注意的是,上述对第一待编码块的说明仅为示例,第一待编码块的数量还可以是其它值。例如,采用图5b所示的第一待编码块时,理论上第一待编码块的数量可以趋近于无限大,即M趋近于无限大,本实施例不作限定。
下面对任意一个信息比特块的Q个信息比特子块的排列方式进行详细的说明。对于任意一个信息比特块,该信息比特块包括的Q个信息比特子块可以按照第一顺序分别置于Q个第一待编码块中。第一顺序为每一个信息比特块的第q个信息比特子块位于所在第一待编码块的第(q-1)*K/Q+1至第q*K/Q可靠的位置。
下面以第一待编码块采用如图5d中的第一待编码块为例进行说明。请参见图6,假设K=256,Q=4,M=6。对于图6中的第一个信息比特块,该信息比特块包括256个信息比特。根据上文实施例的描述,第一通信设备可以获取a 1、a 2、a 3和a 4分别包括64个信息比特。那么按照第一顺序,a 1将置于第一个第一待编码块的第1至第64可靠的位置,a 2将置于第二个第一待编码块的第65至第128可靠的位置,a 3将置于第三个第一待编码块的第129至第192可靠的位置,a 4将置于第四个第一待编码块的第193至第256可靠的位置, 如图6所示。需要注意的是,每一个第一待编码块的位置从左向右可靠度逐渐增加,即最右的位置为第1可靠的位置,向左可靠度依次降低。
又例如,对于图6中的第二个信息比特块,该信息比特块也包括256个信息比特。类似的,第一通信设备可以获取b 1、b 2、b 3和b 4分别包括64个信息比特。那么按照第一顺序,b 1将置于第二个第一待编码块的第1至第64可靠的位置,b 2将置于第三个第一待编码块的第65至第128可靠的位置,b 3将置于第四个第一待编码块的第129至第192可靠的位置,b 4将置于第五个第一待编码块的第193至第256可靠的位置,如图6所示。可以理解的是,第三个至第六个信息比特块中的256个信息比特的排列方式也类似,在此不再赘述。
S303,第一通信设备对M个第一待编码块分别进行polar码编码,获取M个第一编码块;
S304,第一通信设备向第二通信设备发送M个第一编码块;对应的,第二通信设备接收第一通信设备发送的M个第一编码块。
第一通信设备可以对M个第一待编码块分别进行polar码编码,得到M个第一编码块。其中,polar码编码后的输出的M个第一编码块为级联合并在一起的多个编码块。例如,第一通信设备第一次传输时,第一待编码块采用如图5a中的第一待编码块。那么5个第一待编码块以及各个第一待编码块中的信息比特子块的排序如图7a所示。
又例如,第一通信设备第一次传输时,第一待编码块采用如图5b中的第一待编码块。那么6个第一待编码块以及各个第一待编码块中的信息比特子块的排序如图7b所示。类似的,若第一通信设备第一次传输时,第一待编码块采用如图5c中的第一待编码块。那么6个第一待编码块以及各个第一待编码块中的信息比特子块的排序如图7c所示。若第一通信设备第一次传输时,第一待编码块采用如图5d中的第一待编码块。那么6个第一待编码块以及各个第一待编码块中的信息比特子块的排序如图7d所示。
下面对第一编码块的码率进行分析。例如,如图7a所示的5个第一待编码块编码后为5个polar码块,其中,M=5,Q=3。其总码率为(R/3+2R/3+R+2R/3+R/3)/5=3R/5。又例如,如图7b所示的6个第一待编码块编码后为6个polar码块。其中,M=6,Q=3。总码率为(R/3+2R/3+R+R+R+R)/6=5R/6。可见,相较于图7a,图7b中的第一待编码块的总码率更大,即更接近于码率R。
又例如,如图7c所示的6个第一待编码块编码后为6个polar码块。其中,M=6,Q=2。总码率为(R/2+R+R+R+R+R)/6=11R/12。可见,相较于图7b,图7c中的第一待编码块的总码率更大,即M/Q的比值越大时,总码率越接近于R。
再例如,如图7d所示的6个第一待编码块编码后为6个polar码块。其中,M=6,Q=4。总码率为(R/4+R/2+3R/4+R+R+R)/6=3R/4。可见,相较于图7a,图7d中的第一待编码块的总码率更大,即更接近于码率R。
第一通信设备对信息比特编码完成后,可以将M个第一编码块信道经过星座调制,然后将经过星座调制后的数据通过下行数据信道发送给第二通信设备。对应的,第二通信设备将接收编码调制后的数据,并对接收到的编码调制后的数据先解调再解码,以获取第一通信设备传输的原始数据。其中,第一通信设备传输的原始数据即M个第一待编码块承载的多个信息比特。
需要注意的是,根据香农第二定理,当信道的信息传输率不超过信道容量时,采用合适的信道编码方法可以实现任意高的传输可靠性,但若信息传输率超过了信道容量,就不 可能实现可靠的传输。通常情况下,一次传输不能保证所有的信息比特的可靠传输,即不能确保信道容量大于或等于每一个第一编码块的码率。那么第一通信设备可以向第二通信设备重传数据。
S305,当需要重传时,第一通信设备将每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第二待编码块中的Q个第二待编码块中。
第一通信设备向第二通信设备第一次传输M个第一编码块后,若第二通信设备无法正确译码,第二通信设备可以请求重传。对应的,当需要重传时,第一通信设备可以重新将X个信息比特块置于M个第二待编码块中。其中,第二待编码块用于承载第一通信设备第二次向第二通信设备发送的待编码数据。类似的,第二待编码块的数量M满足M=X+Q-1。其中,任意一个第二待编码块至少承载一个信息比特子块,至多承载Q个信息比特子块。
需要注意的是,第二待编码块以及第二待编码块承载的多个信息比特子块的排列按照第二顺序,第二顺序与第一顺序满足映射关系。可选的,第二顺序为每一个所述信息比特块的第q个信息比特子块位于所在第二待编码块的第(Q-q)*K/Q+1至第(Q-q+1)*K/Q可靠的位置。
请参见图8a,图8a为本申请实施例提供的一种第一待编码块和第二待编码块的示意图。其中,对于每一个信息比特块中的Q个信息比特子块,图8a所示的一种第二待编码块中的信息比特子块的排列顺序为图5d所示的一种第一待编码块中的信息比特子块的排列顺序的反序,如图8a所示。其中,K=256,M=6,Q=4。
例如,对于第一个信息比特块(a 1,a 2,a 3,a 4),该信息比特块的信息比特子块a 1位于第四个第二待编码块的第193至第256可靠的位置,即位于第一次传输时a 4对应的位置。a 2位于第三个第二待编码块的第129至第192可靠的位置,即位于第一次传输时a 3对应的位置。a 3位于第二个第二待编码块的第65至第128可靠的位置,即位于第一次传输时a 2对应的位置。a 4位于第一个第二待编码块的第1至第64可靠的位置,即位于第一次传输时a 1对应的位置。可见,对于第一个信息比特块,第一个信息比特块的4个信息比特子块在第二待编码块中的排列顺序为该信息比特块的4个信息比特子块在第一待编码块中的排列顺序的反序。
又例如,对于第二个信息比特块(b 1,b 2,b 3,b 4),该信息比特块的信息比特子块b 1位于第五个第一待编码块的第193至第256可靠的位置,即位于第一次传输时b 4对应的位置。b 2位于第四个第一待编码块的第129至第192可靠的位置,即位于第一次传输时b 3对应的位置。b 3位于第三个第一待编码块的第65至第128可靠的位置,即位于第一次传输时b 2对应的位置。b 4位于第二个第一待编码块的第1至第64可靠的位置,即位于第一次传输时b 1对应的位置。可见,对于第二个信息比特块,第二个信息比特块的4个信息比特子块在第二待编码块中的排列顺序也为该信息比特块的4个信息比特子块在第一待编码块中的排列顺序的反序。可以理解的是,第三个至第六个信息比特块中的256个信息比特的排列方式也类似,在此不再赘述。
可选的,若K/Q的值不为整数或者不为2的次幂,则还需要进行速率匹配。需要指出的是,本申请中的方案与到底采用何种速率匹配方案关系不大,因此采用通用的速率匹配方案即可。
可选的,第一顺序和第二顺序满足以下映射关系:
Figure PCTCN2021082192-appb-000047
其中,a q为任意一个信息比特块的Q个信息比特子块中的任意一个信息比特子块,A t为任意一个信息比特子块映射后对应的信息比特子块,F为polar码的生成矩阵,J为正整数且满足K/Q=2 J,P为正整数且满足2 P-1≤Q≤2 P;t满足1≤t≤2 P
请参见图8b,图8b为本申请实施例提供的一种第二待编码块的示意图。其中,对于每一个信息比特块中的Q个信息比特子块,图8b所示的一种第二待编码块中的信息比特子块的排列顺序与图5d所示的一种第一待编码块中的信息比特子块的排列顺序一致,但是每一个信息比特子块为映射后的信息比特子块,如图8b所示。其中,M=6,Q=4。
例如,对于图8b中的六个信息比特块分别为(a 1,a 2,a 3,a 4),(b 1,b 2,b 3,b 4),(c 1,c 2,c 3,c 4),(d 1,d 2,d 3),(e 1,e 2)和(f 1)。由于每一个信息比特块中的信息比特子块的数量不为2的次幂,则对该信息比特块进行处理时,需要进行补零的处理,以使信息比特块在映射时采用的是完整的polar码生成矩阵。需要注意的是,若不对该信息比特块进行补零的处理,那么该信息比特块在映射时采用的是polar码生成矩阵的子矩阵。
其中,由于2 P-1≤Q≤2 P,可以确定P=2。那么映射后的三个信息比特块分别都包括四个信息比特子块,且映射后的信息比特块与映射前的信息比特块的关系满足以下关系:
[A 1,A 2,A 3,A 4]=[a 1,a 2,a 3,a 4]*F
[B 1,B 2,B 3,B 4]=[b 1,b 2,b 3,b 4]*F
[C 1,C 2,C 3,C 4]=[c 1,c 2,c 3,c 4]*F
[D 1,D 2,D 3,D 4]=[0,d 1,d 2,d 3]*F
[E 1,E 2,E 3,E 4]=[0,0,e 1,e 2]*F
其中,第一通信设备将每一个映射后的信息比特块中的四个信息比特子块按照第一顺序置于Q个第二待编码块中,如图8b所示。
S306,第一通信设备对M个第二待编码块分别进行polar码编码,获取M个第二编码块;
S307,第一通信设备向第二通信设备发送M个第二编码块;对应的第二通信设备接收第一通信设备发送的M个第二编码块。
第一通信设备可以对M个第二待编码块分别进行polar码编码,得到M个第二编码块。
可以理解的是,对第二编码块的码率分析可以参考上文实施例中对第一编码块的码率分析,在此不再赘述。
类似的,第一通信设备对信息比特编码完成后,可以将M个第二编码块信道经过星座调制,然后将经过星座调制后的数据通过下行数据信道发送给第二通信设备。对应的,第二通信设备将接收编码调制后的数据,并对接收到的编码调制后的数据进行数据解调。第二通信设备可以将接收到的M个第一编码块和M个第二编码块进行合并译码,以获取第一通信设备传输的原始数据。其中,第一通信设备传输的原始数据即M个第一待编码块承载的多个信息比特。
S308,第二通信设备将M个第一编码块和M个第二编码块进行合并译码,获取译码数据。
第二通信设备在收到第一通信设备第一次和第二次传输的数据后,可以将两次接收到的数据进行合并译码。其中,本实施例所述的合并译码是一种交互的流程:第二通信设备首先对第一编码块译码,可能译出某些部分;然后再对第二编码块进行译码,并且对第二编码块译码时可能会用到之前第一编码块译码时译出的某些部分;反之亦然。
其中,根据香农第二定理,对于两次传输的情况,当两次传输的信道容量之和大于或等于码率R时,第二通信设备总是可以通过本实施例所述的合并译码的方式对第一编码块和第二编码块实现可靠译码。
具体的,若第一通信设备两次传输的信道容量之和大于或等于码率R,第二通信设备译码获取第一待编码块承载的一个信息比特块包括的k 1个信息比特子块
Figure PCTCN2021082192-appb-000048
k 1满足1≤k 1≤Q;
第二通信设备译码获取第二待编码块承载的该信息比特块包括的k 2个信息比特子块
Figure PCTCN2021082192-appb-000049
k 2满足1≤k 2≤Q,k 1+k 2≥Q;
第二通信设备获取该信息比特块包括的Q个信息比特子块为[a 1,a 2,...,a Q]。
举例来说,假设第一通信设备第一次传输的信道容量大于或等于R/3,第二次传输的信道容量大于或等于2R/3。那么第一通信设备两次传输的信道容量之和大于或等于码率R,即两次传输即可实现正确译码。
第一通信设备第一次传输和第二次传输的第一编码块和第二编码块如图8c所示。其中,第一通信设备第一次传输的第一个和第五个第一编码块的码率为R/3,第二个和第四个第一编码块的码率为2R/3,第三个第一编码块的码率为R。根据香农第二定理,第一个和第五个第一编码块的码率R/3小于或等于第一次传输的信道容量R/3,那么第一个和第五个第一编码块可以译码出来,即a 1和c 3可以译码出来。但是,剩余的信息比特不能确保被成功译码。
其中,第一通信设备第二次传输的第一个和第五个第二编码块的码率为R/3,第二个和第四个第二编码块的码率为2R/3,第三个第二编码块的码率为R。根据香农第二定理,第一个和第五个第二编码块的码率R/3小于或等于第二次传输的信道容量2R/3,那么第一个和第五个第二编码块可以译码出来,即a 3和c 1可以译码出来。第二个和第四个第二编码块的码率为2R/3,小于或等于第二次传输的信道容量2R/3,那么第二个和第四个第二编码块也可以译码出来,即a 2,b 3,b 1和c 2可以译码出来。但是,剩余的信息比特不能确保被成功译码。
在获取a 3和c 1后,第一次传输时的第三个第一编码块的码率降为R/3。根据香农第二定理,由于第一次传输的信道容量大于或等于R/3,那么第三个第一编码块也可以译码出来,即b 2可以译码出来。
综上所述,第一通信设备两次传输的信道容量之和大于或等于码率R时,第一通信设备第两次传输的所有信息比特a 1,a 2,a 3,b 1,b 2,b 3,c 1,c 2,c 3均可以被解出,即实现所有信息比特的可靠传输。
需要注意的是,本申请所述的合并译码还可以包括以下一种特殊的合并译码:第一通信设备第一次传输时,信道容量为零,那么第二通信设备无法译码任何数据。第一通信设备第二次传输时,信道容量大于或等于码率R,那么第二次传输后,第二通信设备可以将所有的原始数据译码出来。可见,上述特殊的情况下,两次传输的信道容量之和大于或等于码率R,也满足合并译码的条件,最终也实现了正确译码。
下面对第一通信设备两次传输可以成功译码的区域以及码率损失区域进行分析说明。请参见图9,图9为Q=3时,第一通信设备两次传输可以成功译码的区域以及码率损失区域的示意图。其中,横坐标表示第一次传输的信道容量,纵坐标表示第二次重传的信道容量,斜线阴影区域表示在此区域内两次传输的信道容量之和小于码率R,无法实现可靠传输。斜线阴影区域以外的部分是可以实现可靠传输的区域,其中,横线阴影区域代表码率 损失的区域。
本申请实施例提供一种数据处理方法,该方法由第一通信设备和第二通信设备之间的交互实现。其中,第一通信设备向第二通信设备初传M个第一编码块时,M个第一编码块中的多个信息比特子块按照第一顺序排列,有利于第二通信设备正确译码。若第二通信设备译码失败,第一通信设备可以向第二通信设备重传M个第二编码块,M个第二编码块中的多个信息比特子块按照第二顺序排列,且第二顺序与第一顺序满足映射关系。上述多个信息比特子块的排序方式有利于第二通信设备根据第一编码块和第二编码块正确译码,即两次传输即可正确译码。只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,第一通信设备就能实现接近于信道容量的传输。
基于图3所示的实施例中的描述,下面对第一通信设备需要进行三次传输才能进行正确译码的情况进行详细的描述。请参见图10,图10为本申请实施例提供的另一种数据处理方法,该数据处理方法可以由第一通信设备和第二通信设备之间交互执行,包括S1001至S1011。其中,S1001至S1007与上述图3实施例中的S301至S307的具体实现方式相似,在此不再赘述。其中S1008至S1011具体包括:
S1008,当需要重传时,第一通信设备将每一个信息比特块的Q个信息比特子块按照第二顺序置于M个第三待编码块中的Q个第三待编码块中。
根据S305中的描述,第二顺序与第一顺序满足映射关系。其中,第二顺序为每一个所述信息比特块的第q个信息比特子块位于所在第二待编码块的第(Q-q)*K/Q+1至第(Q-q+1)*K/Q可靠的位置。或者,第一顺序和第二顺序满足以下映射关系:
Figure PCTCN2021082192-appb-000050
那么第一通信设备在第三次传输时,第一通信设备将每一个信息比特块的Q个信息比特子块也按照第二顺序置于M个第三待编码块中的Q个第三待编码块中。
需要注意的是,为了提高成功译码的概率,第一通信设备在第二次传输时采用的第二顺序与在第三次传输时采用的第二顺序是不相同的。请参见图11a,图11a为本申请实施例提供的一种三次传输时待编码块的示意图。其中,第一通信设备在第二次传输时采用的第二顺序为反序,则第一通信设备在第三次传输时采用的第二顺序为映射后的信息比特块按照第一顺序置于第三待编码块中。
可选的,请参见图11b,图11b为本申请实施例提供的另一种三次传输时的待编码块的示意图。其中,第一通信设备在第二次传输时采用的第二顺序为映射后的信息比特块按照第一顺序置于第二待编码块中,则第一通信设备在第三次传输时采用的第二顺序为反序。
S1009,第一通信设备对M个第三待编码块分别进行polar码编码,获取M个第三编码块;
S1010,第一通信设备向第二通信设备发送M个第三编码块。
第一通信设备可以对M个第三待编码块分别进行polar码编码,得到M个第三编码块。其中,对第三编码块进行polar码编码的过程可以参考图3实施例中对第一编码块进行polar码编码的具体实现方式的描述,在此不再赘述。可以理解的是,对第三编码块的码率分析也可以参考上文实施例中对第一编码块的码率分析,在此不再赘述。
可选的,第一通信设备对信息比特编码完成后,可以将M个第三编码块信道经过星座调制,然后将经过星座调制后的数据通过下行数据信道发送给第二通信设备。对应的,第二通信设备将接收编码调制后的数据,并对接收到的编码调制后的数据进行数据解调。第 二通信设备可以将接收到的M个第一编码块、M个第二编码块以及M个第三编码块进行译码,以获取第一通信设备传输的原始数据。其中,第一通信设备传输的原始数据即M个第一待编码块承载的多个信息比特。
S1011,第二通信设备将M个第一编码块、M个第二编码块和M个第三编码块进行合并译码,获取译码数据。
第二通信设备在收到第一通信设备第一次、第二次和第三次传输的数据后,可以将三次接收到的数据进行合并译码。其中,与两次传输后的合并译码类似,三次传输后的合并译码也是一种交互的流程:第二通信设备首先对第一编码块译码,可能译出某些部分;然后再对第二编码块进行译码,并且对第二编码块译码时可能会用到之前第一编码块译码时译出的某些部分;最后再对第三编码块进行译码,并且对第三编码块译码时可能会用到之前第一编码块和第二编码块译码时译出的某些部分;反之亦然。
其中,根据香农第二定理,对于三次传输的情况,当三次传输的信道容量之和大于或等于码率R时,第二通信设备总是可以通过本实施例所述的合并译码的方式对第一编码块、第二编码块和第三编码块实现可靠译码。

其中,对于图12a中的映射关系,由于各个信息比特块包括的信息比特子块的数量不为2的次幂,则对该信息比特子块进行处理时,需要进行补零的处理,以使信息比特块在映射时采用的是完整的polar码生成矩阵。需要注意的是,若不对该信息比特块进行补零的处理,那么该信息比特块在映射时采用的是polar码生成矩阵的子矩阵。
其中,由于2 P-1≤Q≤2 P,可以确定P=2。那么映射后的信息比特块与映射前的信息比特块的关系满足以下关系:
[A 1,A 2,A 3,A 4]=[0,a 1,a 2,a 3]*F
[B 1,B 2,B 3,B 4]=[0,b 1,b 2,b 3]*F
[C 1,C 2,C 3,C 4]=[0,c 1,c 2,c 3]*F
[D 1,D 2,D 3,D 4]=[0,d 1,d 2,d 3]*F
[E 1,E 2,E 3,E 4]=[0,0,e 1,e 2]*F
第一通信设备第一次传输的第一个第一编码块的码率为R/3,第二个第一编码块的码率为2R/3,第三个至第六个第一编码块的码率为R。根据香农第二定理,第一个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第一个第一编码块可以译码出来,即a 1可以译码出来。但是,剩余的信息比特不能确保被成功译码。
第一通信设备第二次传输的第一个第二编码块的码率为R/3,第二个第二编码块的码率为2R/3,第三个至第六个第二编码块的码率为R。根据香农第二定理,第一个第二编码块的码率R/3小于或等于第二次传输的信道容量,那么第一个第二编码块可以译码出来,即a 3可以译码出来。但是,剩余的信息比特不能确保被成功译码。
第一通信设备第三次传输的第一个第三编码块的码率为R/3,第二个第三编码块的码率为2R/3,第三个至第六个第三编码块的码率为R。根据香农第二定理,第一个第三编码块的码率R/3小于或等于第三次传输的信道容量,那么第一个第三编码块可以译码出来,即A 1可以译码出来。但是,剩余的信息比特不能确保被成功译码。
在获取a 1,a 3和A 1后,根据比特间关系式[A 1,A 2,A 3,A 4]=[0,a 1,a 2,a 3]*F,第一通信设备可以译码得到a 2,A 2和A 4。译码得到a 2后,A 3也可以译码出来。
在获取a 2和A 2后,图12a中的第二个第一编码块的码率降低为R/3。根据香农第二定理,第二个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第二个第一编码块可以译码出来,即b 1可以译码出来。类似的,第二个第二编码块的码率降低为R/3,第二个第三编码块的码率降低为R/3。那么b 3和B 1也可以译码出来。
在获取b 1,b 3和B 1后,根据比特间关系式[B 1,B 2,B 3,B 4]=[0,b 1,b 2,b 3]*F,第一通信设备可以译码得到b 2,B 2,B 3和B 4
在获取a 1,a 3,A 3,b 2和B 2后,图12a中的第三个第一编码块的码率降低为R/3。根据香农第二定理,第三个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第三个第一编码块可以译码出来,即c 1可以译码出来。类似的,第三个第二编码块的码率降低为R/3,第三个第三编码块的码率降低为R/3。那么c 3和C 1也可以译码出来。
在获取c 1,c 3和C 1后,根据比特间关系式[C 1,C 2,C 3,C 4]=[0,c 1,c 2,c 3]*F,第一通信设备可以译码得到c 2,C 2,C 3和C 4
在获取b 1,b 3,B 3,c 2和C 2后,图12a中的第四个第一编码块的码率降低为R/3。根据香农第二定理,第四个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第四个第一编码块可以译码出来,即d 1可以译码出来。类似的,第四个第二编码块的码率降低为R/3,第四个第三编码块的码率降低为R/3。那么d 3和D 1也可以译码出来。
在获取d 1,d 3和D 1后,根据比特间关系式[D 1,D 2,D 3,D 4]=[0,d 1,d 2,d 3]*F,第一通信设备可以译码得到d 2,D 2,D 3和D 4
在获取c 1,c 3,C 3,d 2和D 2后,图12a中的第五个第一编码块的码率降低为R/3。根据香农第二定理,第五个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第五个第一编码块可以译码出来,即e 1可以译码出来。类似的,第五个第二编码块的码率 降低为R/3,第五个第三编码块的码率降低为R/3。那么e 2和E 1也可以译码出来。
在获取e 1,e 2和E 1后,根据比特间关系式[E 1,E 2,E 3,E 4]=[0,0,e 1,e 2]*F,第一通信设备可以译码得到E 2。在获取d 3和e 2后,图12a中的第六个第一编码块的码率降低为R/3。根据香农第二定理,第六个第一编码块的码率R/3小于或等于第一次传输的信道容量,那么第六个第一编码块可以译码出来,即f 1可以译码出来。
综上所述,第一通信设备三次传输的信道容量之和大于或等于码率R时,第一通信设备第三次传输的所有信息比特a 1,a 2,a 3,b 1,b 2,b 3,c 1,c 2,c 3,d 1,d 2,d 3,e 1,e 2,f 1均可以被解出,即实现所有信息比特的可靠传输。
又例如,请参见图12b,图12b为本申请实施例提供的另一种第一通信设备第一次传输的第一编码块、第二次传输的第二编码块和第三次传输的第三编码块的示意图。其中,Q=2。图12b中的第一编码块的排序与图7c中的第一编码块的排序一致。其中,对于每一个信息比特块中的Q个信息比特子块,图12b中的第二编码块中的信息比特子块的排列顺序为图7c中的第一编码块中的信息比特子块的排列顺序的反序,第三编码块中的信息比特子块为图7c中的第一编码块中的信息比特子块映射后的信息比特子块按照第一顺序排列。
其中,对于图12b中的映射关系,各个映射后的信息比特块与映射前的信息比特块的关系满足以下关系:
[A 1,A 2]=[a 1,a 2]*F
[B 1,B 2]=[b 1,b 2]*F
[C 1,C 2]=[c 1,c 2]*F
[D 1,D 2]=[d 1,d 2]*F
[E 1,E 2]=[e 1,e 2]*F
又例如,请参见图12c,图12c为本申请实施例提供的另一种第一通信设备第一次传输的第一编码块、第二次传输的第二编码块和第三次传输的第三编码块的示意图。其中,Q=4。图12b中的第一编码块的排序与图7c中的第一编码块的排序一致。其中,对于每一个信息比特块中的Q个信息比特子块,图12b中的第二待编码块中的信息比特子块的排列顺序为图7c中的第一待编码块中的信息比特子块的排列顺序的反序,第三待编码块中的信息比特子块为图7c中的第一待编码块中的信息比特子块映射后的信息比特子块按照第一顺序排列。
其中,对于图12c中的映射关系,由于图12c中包括进行特殊的处理的信息比特块,该信息比特块包括的信息比特子块的数量不为2的次幂,则对该信息比特子块进行处理时,需要进行补零的处理,以使信息比特块在映射时采用的是完整的polar码生成矩阵。需要注意的是,若不对该信息比特块进行补零的处理,那么该信息比特块在映射时采用的是polar码生成矩阵的子矩阵。
其中,由于2 P-1≤Q≤2 P,可以确定P=2。那么映射后的信息比特块与映射前的信息比特块的关系满足以下关系:
[A 1,A 2,A 3,A 4]=[a 1,a 2,a 3,a 4]*F
[B 1,B 2,B 3,B 4]=[b 1,b 2,b 3,b 4]*F
[C 1,C 2,C 3,C 4]=[c 1,c 2,c 3,c 4]*F
[D 1,D 2,D 3,D 4]=[0,d 1,d 2,d 3]*F
[E 1,E 2,E 3,E 4]=[0,0,e 1,e 2]*F
可以理解的是,图12b和图12c所示的三次传输可以正确译码的条件也为三次传输的信道容量之和大于或等于码率R,那么第二通信设备总是可以通过本实施例所述的合并译码的方式对第一编码块、第二编码块和第三编码块实现可靠译码。其中,图12b和图12c所示的三次传输的译码过程请参考图12a所示的实施例中的具体实现方式的描述,在此不再赘述。
本申请实施例提供一种数据处理方法,该方法由第一通信设备和第二通信设备之间的交互实现。其中,第一通信设备向第二通信设备初传M个第一编码块时,M个第一编码块中的多个信息比特子块按照第一顺序排列,有利于第二通信设备正确译码。若第二通信设备译码失败,第一通信设备可以向第二通信设备重传M个第二编码块,M个第二编码块中的多个信息比特子块按照第二顺序排列,且第二顺序与第一顺序满足映射关系。若第二通信设备仍然译码失败,第一通信设备还可以向第二通信设备重传M个第三编码块,第三编码块中的多个信息比特子块的排列方式与第二编码块中的多个信息比特子块的排列方式相关联。上述多个信息比特子块的排序方式有利于第二通信设备根据第一编码块、第二编码块和第三编码块正确译码,即三次传输即可正确译码。只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,第一通信设备就能实现接近于信道容量的传输。
基于图3所示的实施例中的描述,下面对第一通信设备需要进行四次或四次以上传输才能进行正确译码的情况进行详细的描述。为了便于描述,以下示例以第一通信设备需要进行四次传输为例进行说明。可以理解的是,当第一通信设备需要进行四次以上传输时,可以参考四次传输的具体实现方式。
请参见图13,图13所示的示例中假设第一通信设备总的传输次数为四次,该数据处理方法可以由第一通信设备和第二通信设备之间交互执行,具体包括以下步骤:
S1301,第一通信设备获取X个信息比特块,一个信息比特块被划分为Q个信息比特子块;
S1302,当需要重传且第一通信设备传输的总次数为四次时,第一通信设备将每一个信息比特块的Q个信息比特子块进行处理。
当第一通信设备的传输次数为四次时,由于不存在二进制域上的UDM矩阵,第一通信设备对信息比特子块的处理无法在二进制域中进行。那么第一通信设备在对每一个信息比特块进行处理时,可以将每一个信息比特块[a 1,a 2,...,a Q]从二进制域映射至2 w进制域,且映射后的任意一个信息比特块满足

其中,

转换后对应的信息比特子块,H n为在2 w进制域上的K/w×K/w的UDM,n用于指示第n次传输;n满足n∈[1,2,...,N],N为第一通信设备传输的总次数,N为大于3的正整数。
第一通信设备再将

进行反映射,得到反映射后的对应的信息比特块满足[A n,1,A n,2,...,A n,Q]。其中,反映射后的A n,Q为长度为K/Q的二进制序列。
可见,通过上述处理流程,第一通信设备在四次或者四次以上传输时,可以将信息比特子块进行处理后,再进行后续的排序编码。
S1303,第一通信设备将处理后的每一个信息比特块的信息比特子块按照第一顺序置于M个第一待编码块中;
S1304,第一通信设备对M个第一待编码块分别进行polar码编码,获取M个第一编码块;
S1305,第一通信设备向第二通信设备发送M个第一编码块;
S1306,当需要重传时,第一通信设备将处理后的每一个信息比特块的信息比特子块按照第一顺序置于M个第二待编码块中;
S1307,第一通信设备对M个第二待编码块分别进行polar码编码,获取M个第二编码块;

S1311,第一通信设备向第二通信设备发送M个第三编码块;
S1312,当需要重传时,第一通信设备将处理后的每一个信息比特块的信息比特子块按照第一顺序置于M个第四待编码块中;
S1313,第一通信设备对M个第四待编码块分别进行polar码编码,获取M个第四编码块;
S1314,第一通信设备向第二通信设备发送M个第四编码块。
请参见图14,图14为本申请实施例提供的一种第一通信设备第一次传输的第一编码块、第二次传输的第二编码块、第三次传输的第三编码块和第四次传输的第四编码块的示意图。其中,Q=3,M=5。其中,第一次传输的第一编码块中的信息比特子块采用第一顺序排列。例如,A 1,1,A 1,2,A 1,3分别表示第一数据流承载的第一编码块中的信息比特子块,上述信息比特子块为原始信息比特子块中的a 1,a 2,a 3进行处理后的信息比特子块。
第一次传输的第一编码块确定后,第一通信设备第一次向第二通信设备发送该M个第一编码块。
第二次传输的第二编码块中的信息比特子块按照第一顺序排列。例如,A 2,1,A 2,2,A 2,3分别表示第二数据流承载的第二编码块中的信息比特子块,上述信息比特子块为原始信息比特子块中的a 1,a 2,a 3进行处理后,并且不同于A 1,1,A 1,2,A 1,3的信息比特子块。
第二次传输的第二编码块确定后,第一通信设备第二次向第二通信设备发送该M个第二编码块。
第三次传输的第三编码块中的信息比特子块按照第一顺序排列。例如,A 3,1,A 3,2,A 3,3分别表示第三数据流承载的第三编码块中的信息比特子块。上述信息比特子块为原始信息比特子块中的a 1,a 2,a 3进行处理后,并且不同于A 1,1,A 1,2,A 1,3和A 2,1,A 2,2,A 2,3的信息比特子块。
第三次传输的第三编码块确定后,第一通信设备第三次向第二通信设备发送该M个第三编码块。
第四次传输的第四编码块中的信息比特子块按照第一顺序排列。例如,A 4,1,A 4,2,A 4,3分别表示第四数据流承载的第四编码块中的信息比特子块。上述信息比特子块为原始信息比特子块中的a 1,a 2,a 3进行处理后,并且不同于A 1,1,A 1,2,A 1,3、A 2,1,A 2,2,A 2,3和A 3,1,A 3,2,A 3,3的信息比特子块。
第四次传输的第四编码块确定后,第一通信设备第一次向第二通信设备发送该M个第四编码块。

举例来说,假设第一通信设备第一次传输的信道容量大于或等于R/4,第二次传输的信道容量大于或等于R/4,第三次传输的信道容量大于或等于R/4,第四次传输的信道容量大于或等于R/4。那么第一通信设备四次传输的信道容量之和大于或等于码率R,即四次传输可实现正确译码。
本申请实施例提供一种数据处理方法,该方法由第一通信设备和第二通信设备之间的交互实现。其中,第一通信设备向第二通信设备初传M个第一编码块时,M个第一编码块中的多个信息比特子块按照第一顺序排列,有利于第二通信设备正确译码。若第二次传 输和第三次传输后第二通信设备仍然译码失败,第一通信设备可以向第二通信设备重传M个第n编码块,第n编码块中的多个信息比特子块的排列方式与第一编码块中的多个信息比特子块的排列方式相关联。上述多个信息比特子块的排序方式有利于第二通信设备根据第一编码块至第n编码块正确译码。只要满足多次传输的信道容量之和大于或等于信息传输速率的条件,第一通信设备就能实现接近于信道容量的传输。
