技术领域

背景技术
由于移动通信存在干扰和衰落,在信号传输过程中将出现差错,故对数字信号必须采用纠错技术或检错技术(或者说,即纠错编码技术或检错编码技术),以增强数据在信道中传输时抵御各种干扰的能力,提高系统的可靠性,纠错编码技术或检错编码技术也可以称为信道编码技术。
目前,已知有多种用于上述信道编码技术的编码方式,不同的编码方式(也可以称为,信道编码方式)的纠错能力也相异。
并且,在现有技术中,在针对同一种业务的传输过程中使用同一种编码方式。
随着通信技术的发展,可供无线通信使用的频域资源越来越灵活多变,例如,对于一种业务的数据,可以使用系统为另一种业务预留的频域资源进行传输。随之而来,不同频域资源上的无线通信对于纠错能力的要求可能不同,对于同一业务使用单一的编码方式已经无法满足无线通信对于准确性和可靠性的要求。
发明内容

具体实施方式

本申请的方案可以应用于现有的蜂窝通信系统,如全球移动通讯(Global System for Mobile Communication,GSM),宽带码分多址(Wideband Code Division Multiple Access,WCDMA),长期演进(Long Term Evolution,LTE)等系统中,所支持的通信主要是针对语音和数据通信的。本申请的方案也可以应用于下一代通信系统,如5G通信系统。
下一代移动通信系统将不仅支持传统的通信业务,还将支持URLLC业务(Ultra-Reliable and Low Latency Communications,URLLC),URLLC业务一般是紧急业务,对传速可靠性和传输时延要求很高,一般要求在1ms内达到99.999%的传输可靠性。为了保证URLLC业务超高可靠性和超低时延的业务需求,系统需要为URLLC业务分配足够的频域资源用于传输URLLC业务,但是URLLC业务一般是突发的紧急业务,且业务数据包一般都比较小,在没有业务到达时,为URLLC分配的资源会造成一定的资源浪费。同时,对于eMBB业务(enhanced Mobile BroadBand,eMBB),由于其巨大的业务数据又需要很大的频域资源。同时,无线通信系统可用的带宽是有限的,总的频域资源与不同业务的频带需求以及不同业务的频带分配方案存在不足和冗余的问题,根据本申请的方案能够有效解决上述资源分配的问题。

此外,本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,压缩盘(Compact Disc,CD)、数字通用盘(Digital Versatile Disc,DVD)等),智能卡和闪存器件(例如,可擦写可编程只读存储器(Erasable Programmable Read-Only Memory,EPROM)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是使用本申请的传输信息的通信系统的示意图。如图1所示,该通信系统100包括网络设备102,网络设备102可包括多个天线例如,天线104、106、108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(Frequency Division Duplex,FDD)系统中,例如,前向链路118可利用与反向链路120所使用的不同频带,前向链路124可利用与反向链路126所使用的不同频带。
再例如,在时分双工(Time Division Duplex,TDD)系统和全双工(Full Duplex)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如,可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外, 与网络设备通过单个天线向它所有的终端设备发送信号的方式相比,在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。

需要说明的是,在本申请中,发送设备可以是上述网络设备102也可以是终端设备(例如,终端设备116或终端设备122),相对应的,接收端设备可以是上述终端设备(例如,终端设备116或终端设备122),也可以是网络设备102,本申请并未特别限定。
在本申请中,在通信系统中可以传输至少两种业务,其中,在通信系统中,为该至少两种业务中的一种业务(例如,第二业务)配置有预留的时频资源。
在本申请中,“为第二业务预留的时频资源”可以理解为,通信系统或通信协议规定该为第二业务预留的时频资源仅用于传输第二业务的数据;或者说,通信系统或通信协议规定该为第二业务预留的时频资源禁止用于传输除该第二业务以外的业务(例如,第一业务)的数据。
或者,“为第二业务预留的时频资源”也可以理解为,通信系统或通信协议规定该为第二业务预留的时频资源优先用于传输第二业务的数据,例如,在无需传输第二业务的数据时,该为第二业务预留的时频资源可以用于传输其他业务(例如,第一业务)的数据;在需要传输第二业务的数据时,该为第二业务预留的时频资源需要首先确保第二业务的数据的传输,在满足第二业务的数据的传输的前提下,可以利用该为第二业务预留的时频资源中剩余的时频资源传输其他业务(例如,第一业务)的数据。
或者,“为第二业务预留的时频资源”也可以理解为用于传输第二业务的数据的候选时频资源,能够通过该候选时频资源传输的数据可以包括第一业务的数据和第二业务的数据,且所述第二业务的传输优先级高于第一业务的传输优先级,或者说,在出现需要在同一时段内通过候选时频资源传输的第一业务的数据和第二业务的数据时,优先使用候选时频资源传输的第二业务的数据,具体地说,可以首先通过该候选时频资源传输第二业务的数据,当通过候选时频资源传输完毕的第二业务的数据后,可以通过候选时频资源传输第一业务的数据;或者,当该候选时频资源的一部分能够满足第二业务的数据的传输时,可以通过候选时频资源中的剩余部分传输第一业务的数据。
作为示例而非限定,该第一业务可以为增强型移动互联网(enhanced Mobile BroadBand,eMBB)业务。该第二业务可以为超高可靠性与超低时延(Ultra Reliable&Low Latency Communication,URLLC)业务。
具体地说,国际电信联盟无线通信委员会(International Telecommunications Union-Radio Communications Sector,ITU-R)定义了未来5G的3大类应用场景,分别是 增强型移动互联网业务(Enhanced Mobile Broadband,eMBB)、海量连接的物联网业务(Massive Machine Type Communication,mMTC)和超高可靠性与超低时延业务(Ultra Reliable&Low Latency Communication,URLLC),并从吞吐率、时延、连接密度和频谱效率提升等8个维度定义了对5G网络的能力要求。其中,eMBB业务主要要求大速率,广覆盖、传输时延以及移动性。URLLC业务的主要需求为极高可靠性、极低移动性和传输时延,一般要求无线空口在1毫秒(ms)内达到99.999%的传输可靠性。
对于URLLC业务,为了保证其时延要求,要求业务到达基站后就要即刻发送,需要有一定的时频资源用于发送URLLC数据。在5G系统,不同的业务可以复用在一个载波中,复用方式可以为频分复用(Frequency Division Multiplexing,FDM)或者时分复用(Time Division Multiplexing,TDM)。为了保证URLLC的业务需求,现在的研究和标准讨论中,倾向于为URLLC预留一段频带资源(即,为第二业务预留的时频资源的一例),保证URLLC的业务到达时,总有时频资源进行发送,即,如图2所示,在同一个载波中,URLLC与其他业务(如eMBB业务)是频分复用的。
在本申请中,URLLC业务与eMBB业务频分复用,eMBB业务可以临时使用URLLC业务预留的资源,在为URLLC业务预留的资源上,在URLLC业务(具体地说,是业务的数据)到达时,如果在URLLC业务预留的资源上正在传输eMBB业务,则打孔正在传输的eMBB业务,并在打孔位置传输URLLC业务。
以下,为了便于理解和说明,以eMBB业务作为第一业务,以URLLC业务作为第二业务,对本申请的传输数据的方法进行详细说明。
图3是本申请的传输数据的方法300的示意性交互图。
具体地说,在S210,发送设备(或者说,编码端)可以采用编码方式#A(即,第一编码方式的一例)对需要发送至接收设备(或者说,解码端)的eMBB业务的数据(即,第一业务的第一数据的一例,以下,为了便于理解和区分,记做:数据#A)进行编码。
作为示例而非限定,在本申请中,该编码方式#A可以为以下编码方式。
这里,采用编码方式#A编码的对象可以是经过信源编码处理后的数据。即,该编码方式#A可以是信道编码方式。
具体地说,信源编码是一种以提高通信有效性为目的而对信源符号进行的变换,或者说为了减少或消除信源利余度而进行的信源符号变换。具体说,就是针对信源输出符号序列的统计特性来寻找某种方法,把信源输出符号序列变换为最短的码字序列,使后者的各码元所载荷的平均信息量最大,同时又能保证无失真地恢复原来的符号序列。
信源编码的作用之一是设法减少码元数目和降低码元速率,即通常所说的数据压缩;作用之二是将信源的模拟信号转化成数字信号,以实现模拟信号的数字化传输。
信道编码是通过信道编码器和译码器实现的用于提高信道可靠性的理论和方法。信道编码大致分为两类:
①信道编码定理,从理论上解决理想编码器、译码器的存在性问题,也就是解决信道能传送的最大信息率的可能性和超过这个最大值时的传输问题。
②构造性的编码方法以及这些方法能达到的性能界限。
数字信号在传输中往往由于各种原因,使得在传送的数据流中产生误码,从而使接收端产生例如图象跳跃、不连续、出现马赛克等现象。所以通过信道编码这一环节,对数码 流进行相应的处理,使系统具有一定的纠错能力和抗干扰能力,可极大地避免码流传送中误码的发生。误码的处理技术有纠错、交织、线性内插等。
并且,通过信道编码能够提高数据传输效率,降低误码率是信道编码的任务。
信道编码的本质是增加通信的可靠性。但信道编码会使有用的信息数据传输减少,信道编码的过程是在源数据码流中加插一些码元,从而达到在接收端进行判错和纠错的目的,这就是我们常常说的开销。在带宽固定的信道中,总的传送码率也是固定的,由于信道编码增加了数据量,其结果只能是以降低传送有用信息码率为代价了。将有用比特数除以总比特数就等于编码效率了,不同的编码方式,其编码效率有所不同。
作为示例而非限定,在本申请是实施例中,该编码方式#A可以以下编码方式:
例如,发送设备可以采用现有的信道编码方式(以下,为了便于理解,记做:编码方式#A-1)对数据(例如,经过信源编码处理后的数据#A)进行编码处理,以生成多个原始码块(即,M-N个原始第一码块的一例,以下,为了便于理解和区分,记做:原始码块#A1~原始码块#AM-N)。
这里,该M-N可以是大于或等于2的整数,即,原始码块的数量可以为至少两个。
作为实例而非限定,该编码方式#A-1可以是,例如,分组码编码方式、卷积码编码方式、极化码编码方式或turbo码编码方式等。
并且,发送设备基于编码方式#A-1对数据#A进行编码处理的过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
其后,发送设备可以编码方式#A-2对原始码块#A1~原始码块#AM-N进行进一步处理,以获取多个冗余码块(即,N个冗余第一码块的一例,以下,为了便于理解和区分,记做:冗余码块#AM-N+1~冗余码块#AM)。
这里,该N可以是大于或等于1的整数,即,冗余码块的数量可以为至少一个。
作为示例而非限定,在本申请中,可以将该原始码块#A1~原始码块#AM-N作为输入参量,并且,例如,可以为各输入参量分配规定的权重,并采用预设的算法对各输入参量进行运算处理(例如,加运算或减运算等),从而输出冗余码块#AM-N+1~冗余码块#AM
另外,在本申请中,冗余码块可以包括原始码块#A1~原始码块#AM-N中的每个原始码块的分量,或者说,该冗余码块可以是基于原始码块#A1~原始码块#AM-N生成的,从而,在原始码块中的部分(例如,一个)码块在传输过程中缺失(例如,被发送设备打孔而导致缺失)时,能够基于没有缺失的原始码块和该冗余码块恢复出缺失的码块,从而,能够使接收设备准确而可靠地恢复出发送设备所需要发送的数据#A。
需要说明的是,在本申请中,冗余码块的数量可以是一个或多个,本申请并未特别限定,当该冗余码块为一个时,该一个冗余码块可以包括原始码块#A1~原始码块#AM-N中的每个原始码块的分量(或者,每个原始码块的分量经过规定的算法处理后生成的数据);当该冗余码块为多个时,该多个冗余码块可以包括原始码块#A1~原始码块#AM-N中的每个原始码块的分量(或者,每个原始码块的分量经过规定的算法处理后生成的数据),例如,每个冗余码块均可以包括原始码块#A1~原始码块#AM-N中的每个原始码块的分量,或者,一个冗余码块可以包括原始码块#A1~原始码块#AM-N中的一部分原始码块的分量(或者,该部分原始码块的分量经过规定的算法处理后生成的数据),另一个冗余码块可以包括原始码块#A1~原始码块#AM-N中的另一部分原始码块的分量(或者,该部分原始码块的分量 经过规定的算法处理后生成的数据)。
作为示例而非限定,该编码方式#A(或者说,编码方式#A-2)可以为外码(outer code)编码方式。并且,该外码编码方式的具体过程和方法可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
应理解,以上列举的编码方式#A的具体过程仅为示例性说明,本申请并未限定于此。
作为示例而非限定,在本申请是实施例中,该编码方式#A可以为联合编码方式(即,第一编码方式的一例),即,采用联合编码方式对某一数据(以下,为了便于理解和区分,记做:数据#β)进行编码后能够生产多个编码单元(或者说,码块),无需通过该多个编码单元中的全部编码单元,便能够解码出该数据#β,或者说,仅通过该多个编码单元中的一部分编码单元便能够解码出该数据#β。
另外,作为与该联合编码方式不同的编码方式,在本申请中,可以列举单独编码方式(即,第二编码方式的一例),即,采用该单独编码方式某一数据(以下,为了便于理解和区分,记做:数据#γ)进行编码后能够生产多个编码单元(或者说,码块),只有通过该多个编码单元中的全部编码单元,才能够解码出该数据#γ,或者说,仅通过该多个编码单元中的一部分编码单元不能够解码出该数据#γ。
例如,在本申请中,该编码方式#A可以以下编码方式:
发送设备可以先将数据分成多个原始码块,(即,M-N个原始第一码块的一例,记为:原始码块#B1~原始码块#BM-N),这里,该M-N可以是大于或等于1的整数,即,原始码块的数量可以为至少一个。
其后,发送设备可以编码方式#A-2对原始码块#B1~原始码块#BM-N进行进一步处理,以获取多个冗余码块(即,N个冗余第一码块的一例,记为:冗余码块#BM-N+1~冗余码块#BM)。这里,该N可以是大于或等于1的整数,即,冗余码块的数量可以为至少一个。
并且,作为示例而非限定,在本申请中,可以将该原始码块#B1~原始码块#BM-N作为输入参量,并且,例如,可以为各输入参量分配规定的权重,并采用预设的算法对各输入参量进行运算处理(例如,加运算或减运算等),从而输出冗余码块#BM-N+1~冗余码块#BM
之后,作为实例而非限定,发送设备可以采用现有的信道编码方式(编码方式#A-1)对M个第一码块分别进行编码处理,生成M个第一码块(记为码块#A1~码块#AM),该编码方式#A-1可以是,例如,分组码编码方式、卷积码编码方式、极化码编码方式或turbo码编码方式等。
并且,发送设备基于编码方式#A-1对M个第一码块进行编码处理的过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
再例如,在本申请中,例如,通信系统或通信协议可以规定在为第二业务预留的时频资源上传输的第一业务的首个码块不会被打孔,此情况下,发送设备也可以仅将该原始码块#A2~原始码块#AM-N作为输入参量,并且,例如,可以为各输入参量分配规定的权重,并采用预设的算法对各输入参量进行运算处理(例如,加运算,减运算等),从而输出冗余码块#AM-N+1~冗余码块#AM。即,原始码块#A1也可以不参与外码编码,此情况下,冗余码块可以不包括原始码块#A1的分量,或者说,该冗余码块可以是基于原始码块#A2~原始码块#AM-N生成的。
由此,经由编码方式#A对数据#A编码后生成的M个码块(即,M个第一码块的一 例,以下,为了便于理解和区分,记做:码块#A1~码块#AM)包括原始码块#A1~原始码块#AM-N和冗余码块#AM-N+1~冗余码块#AM
其后,发送设备可以从为URLLC业务(即,第二业务的一例)预留的时频资源(以下,为了便于理解和区分,记做,预留资源)中,确定用于承载该码块#A1~码块#AM的时频资源(以下,为了便于理解和区分,记做:时频资源#A1~时频资源#AM)。并将码块#A1~码块#AM承载于该时频资源#A1~时频资源#AM,其中,该码块#A1~码块#AM与该时频资源#A1~时频资源#AM可以一一对应,即,每个码块可以承载于所对应的时频资源上。
需要说明的是,在本申请中,该时频资源#A1~时频资源#AM可以是预留资源中的全部资源,或者,该时频资源#A1~时频资源#AM也可以是预留资源中的部分资源,本申请并未特别限定。
在S220,发送设备可以通过时频资源#A1~时频资源#AM中的部分或全部时频资源,发送码块#A1~码块#AM中的部分或全部码块。
具体地说,在本申请中,在传输码块#A1~码块#AM的过程中,可能存在需要传输URLLC业务的数据(即,第二业务的数据的一例)的情况,由于时频资源#A1~时频资源#AM属于为URLLC业务预留的时频资源,因此,可能存在该时频资源#A1~时频资源#AM中的部分(例如,一个)时频资源需要用于传输URLLC业务的数据的情况。因此,对于码块#A1~码块#AM的传输可以包括以下情况:
情况1
当无需传输URLLC业务的数据时,发送设备可以使用时频资源#A1~时频资源#AM中的全部时频资源(即,第一时频资源的一例)发送该码块#A1~码块#AM中的全部码块。
情况2
当需要传输URLLC业务的数据,且预留资源中除时频资源#A1~时频资源#AM以外的时频资源(以下,为了便于理解和区分,称为:剩余时频资源)能够满足URLLC业务的传输要求时,发送设备可以使用时频资源#A1~时频资源#AM中的全部时频资源(即,第一时频资源的一例)发送该码块#A1~码块#AM中的全部码块,并且,发送设备可以通过该剩余时频资源中的部分或全部时频资源(即,第三时频资源的一例)发送URLLC业务的数据,其中,发生设备基于发送该URLLC业务的数据的过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
情况3
当需要传输URLLC业务的数据,且预留资源中的剩余时频资源不能满足URLLC业务的传输要求时,发送设备可以使用上述剩余时频资源以及时频资源#A1~时频资源#AM中的部分时频资源发送URLLC业务的数据,即,发送设备可以对该码块#A1~码块#AM中部分(例如,1个)码块进行打孔,并将URLLC业务的数据承载于被打孔的码块所对应的时频资源中。从而,此情况下,发送设备使用时频资源#A1~时频资源#AM中的部分时频资源(即,第一时频资源的另一例)发送该码块#A1~码块#AM中的部分码块。并且,发送设备可以通过该剩余时频资源和时频资源#A1~时频资源#AM中的部分时频资源(即,第三时频资源的另一例)发送URLLC业务的数据,其中,发生设备基于发送该URLLC业务的数据的过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
需要说明的是,在上述情况下,发送设备进行打孔的码块可以属于码块#A1~码块#AM 中的原始码块,也可以属于码块#A1~码块#AM中的冗余码块本申请并未特别限定。
并且,以上列举的发送设备进行打孔的码块的数量仅为示例性说明,本申请并未特别限定,只要能够使接收设备基于未打孔的码块准确地恢复出发生设备所需要发送的数据即可。
下面,对于接收设备对数据#A的获取过程进行详细说明。
如上所述,发送设备通过时频资源#A1~时频资源#AM中的部分或全部时频资源(即,第一时频资源的一例)发送了码块#A1~码块#AM中的部分或全部码块之后,在S220,接收设备可以对上述预留资源进行检测,并接收到通过该与预留资源中承载的eMBB业务的码块,即上述码块#A1~码块#AM中的部分或全部码块。
需要说明的是,在本申请中,发送设备和接收设备之间可以通过下行控制信息(Downlink Control Information,DCI)来确定:预留资源中承载的eMBB业务的码块,或者说,用于承载eMBB业务的码块的时频资源(即,第一时频资源的一例)的位置。
另外,在采用上述外码编码方式(即,上述编码方式#A)对eMBB业务的数据进行编码处理时,接收设备还需要区分所传输的eMBB业务的码块的原始码块和冗余码块。
作为示例而非限定,例如,该发送设备还可以向接收设备发送用于指示用于承载冗余码块的时频资源的位置的指示信息(即,第三指示信息的一例)。
或者,例如,该发送设备还可以向接收设备发送用于指示用于承载原始码块的时频资源的位置的指示信息(即,第三指示信息的另一例)。
从而,接收设备能够根据该第三指示信息,从该码块#A1~码块#AM中识别出冗余码块和原始码块。
通过使发送设备通知接收设备该N个冗余第一码块在该第一时频资源中的位置,能够使接收设备容易地确定该M个第一码块中的原始第一码块和冗余第一码块,进而,能够使接收设备容易地基于原始第一码块和冗余第一码块恢复出第一数据。
应理解,以上列举的接收设备区分所传输的eMBB业务的码块的原始码块和冗余码块的方法和过程仅为示例性说明,本申请并未限定于此,例如,通信系统或通信协议还可以预先规定原始码块和冗余码块的排列方式或位置关系,从而,发送设备可以根据上述规定传输原始码块和冗余码块,接收设备可以根据上述规定识别原始码块和冗余码块。
在S230,接收设备可以基于所接收到的eMBB业务的码块(即,上述该码块#A1~码块#AM中的部分或全部码块)中的原始码块和冗余码块,根据编码方式#A(例如,编码方式#A-1和/或编码方式#A2)对该码块#A1~码块#AM,进行解码处理,以获取上述数据#A。
作为示例而非限定,例如,接收设备可以首先尝试使用编码方式#A-1对所接收到的eMBB业务的码块中的原始码块进行解码处理。
如果能够正常解码,则接收设备可以判定为码块#A1~码块#AM中的原始码块未发生缺失(例如,未被打孔),因此可以将解码得到的数据认为是上述数据#A。
如果不能正常解码,则接收设备可以判定为该码块#A1~码块#AM中的原始码块中的部分码块缺失(例如,被打孔),此情况下,接收设备可以根据编码方式#A-2,基于所接收到的eMBB业务的码块中的原始码块和冗余码块,恢复出上述原始码块#A1~原始码块#AM-N,进而基于编码方式#A-1对原始码块#A1~原始码块#AM-N进行解码处理,从而获取上述数据#A。
再例如,接收设备也可以直接根据编码方式#A-2,基于所接收到的eMBB业务的码块中的原始码块和冗余码块,恢复出上述原始码块#A1~原始码块#AM-N,进而基于编码方式#A-1对原始码块#A1~原始码块#AM-N进行解码处理,从而获取上述数据#A。
需要说明的是,接收设备根据编码方式#A-2和所接收到的eMBB业务的码块中的原始码块和冗余码块而恢复出原始码块#A1~原始码块#AM-N的过程,可以是发送设备根据编码方式#A-2和原始码块#A1~原始码块#AM-N生成所接收到的eMBB业务的码块中的原始码块和冗余码块而恢复出冗余码块#AM-N+1~冗余码块#AM的逆向过程,这里,为了避免赘述,省略其详细说明。
作为示例而非限定,在本申请中,发送设备和接收设备在使用为URLLC业务(即,第二业务的一例)预留的时频资源发送eMBB业务(即,第一业务的一例)的数据时,所使用的编码方式(例如,上述编码方式#A)可以是通信系统或通信协议规定的。
即,当系统固定eMBB业务与URLLC业务的频带划分时,发送设备和接收设备能够明确获知预留给URLLC业务的资源,从而,可以通过系统预定义或者通过系统消息,使发送设备和接收设备确定在预留给URLLC业务的资源上采用的编码方式与在分配给eMBB业务的资源上采用的编码方式是否相异,进一步,还可以通过系统预定义或者通过系统消息指示在预留给URLLC业务的资源上采用的编码方式的具体是哪种编码方式。
或者,在本申请中,发送设备和接收设备也可以(例如,通过信令)确定在使用为URLLC业务预留的时频资源发送eMBB业务的数据时所使用的编码方式。
例如,发送设备和接收设备中的一方(例如,发送设备和接收设备中的网络设备)可以向发送设备和接收设备中的另一方(例如,发送设备和接收设备中的终端设备)发送用于指示在使用为URLLC业务预留的时频资源发送eMBB业务的数据时所使用的编码方式的指示信息(即,第一指示信息或第二指示信息的一例)。
或者,发送设备和接收设备中的一方(例如,发送设备和接收设备中的网络设备)可以向发送设备和接收设备中的另一方(例如,发送设备和接收设备中的终端设备)发送用于指示在使用第一时频资源(例如,时频资源#A1~时频资源#AM)发送eMBB业务的数据时所使用的编码方式的指示信息(即,第一指示信息或第二指示信息的一例)。需要说明的,此情况下,该第一时频资源可以通过DCI的指示来确定。
即,当eMBB业务与URLLC业务的频带划分是动态变化的,在每个子帧,则网络设备可以通过例如,下行控制信息(Downlink Control Information,DCI)指示终端设备通过所述下行控制信息DCI调度的数据传输采用的编码方式,如对于eMBB业务,系统默认一种信道编码方式,如编码方式#A-1,在下行控制信息DCI中通知所述下行控制信息DCI调度的数据传输采用的编码方式是否与编码方式#A-1相异,进一步,还可以通过下行控制信息DCI或者系统消息指示与所述系统默认信道编码方式相异的编码方式具体是哪种编码方式。
通过发送设备与接收设备确定需要基于第一编码方式在为第二业务预留的时频资源上传输第一业务的数据,能够使发送设备和接收设备使用相同的编码方式在第一时频资源上传输第一业务的数据,从而能够进一步提高传输的可靠性和准确性。
根据本申请的传输数据的方法,由于第一时频资源属于为第二业务预留的时频资源,当需要传输第二业务的数据时,可能导致由该M-N个原始第一码块和N个冗余第一码块 构成的M个第一码块中的部分码块被打孔,进而导致接收端无法接收到M个第一码块中的一个或多个码块,对此,通过使该第一编码方式为在根据第一数据生成的M-N个原始第一码块的基础上,进一步进行编码处理,以生成N个冗余第一码块,能够使接收设备在未接收到M个第一码块中的一个或多个码块的情况下,仍然能够通过冗余算法获得第一数据,从而能够提高传输的可靠性和准确性。
在S240,发送设备可以采用编码方式#B(即,第二编码方式的一例)对需要发送至接收设备的eMBB业务的数据(即,第一业务的第二数据的一例,以下,为了便于理解和区分,记做:数据#B)进行编码。
这里,采用编码方式#B编码的对象可以是经过信源编码处理后的数据。即,该编码方式#B可以是信道编码方式。
例如,发送设备可以采用编码方式#B对数据(例如,经过信源编码处理后的数据#B)进行编码处理,以生成多个原始码块(即,第二码块的一例)。
作为实例而非限定,该编码方式#B可以是,例如,分组码编码方式、卷积码编码方式、极化码编码方式或turbo码编码方式等。
并且,发送设备基于编码方式#B对数据#B进行编码处理的过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
另外,在本申请中,该编码方式#B与上述编码方式#A-1可以相同也可以相异,本申请并未特别限定。
其后,发送设备确定从为eMBB业务(即,第一业务的一例)分配的时频资源中,确定用于承载该第二码块的时频资源(即,第二时频资源的一例)。即,该第二时频资源属于例如通信系统或通信协议规定的能够用于传输eMBB业务的时频资源,或者说,该第二时频资源不属于为URLLC业务(即,第二业务的一例)预留的时频资源。
在S250,发送设备通过该第二时频资源将第二码块发送至接收设备。
相应地,在S250,接收设备可以通过该第二时频资源接收第二码块,在S260,接收设备可以基于编码方式#B对第二码块进行解码处理,进而获取数据#B。
需要说明的是,在上述S240~S260中描述的数据#B的传输过程可以与现有技术相似,这里,为了避免赘述,省略其详细说明。
即,在本申请中,编码方式#B与编码方式#A不同,或者说,对于eMBB业务,在为URLLC业务预留的时频资源上的传输过程中所使用的编码方式,与在为URLLC业务预留的时频资源以外的时频资源上的传输过程中所使用的编码方式相异。
从而,通过在不同的时频资源上使用纠错能力不同的编码方式,能够基于不同时频资源上的通信情况,选择适当编码方式,从而能够提高传输的准确性和可靠性。
应理解,以上列举的编码方式#A仅为本申请的第一编码方式的一例,本申请的第一编码方式并未特别限定,本申请的第一编码方式也可以是现有技术中的其他信道编码方式,只要使本申请的第一编码方式与第二编码方式相异即可。
例如,在本申请另一实施例中,编码方式#A也可以是如下编码方式,发送设备(或者说,编码设备)可以通过编码器(采用例如,喷泉码编码方式)对数据#A进行编码,从而产生多个(即,M个,该M的值可以为无暇大)编码单元,或者说,产生无限长的码字序列,其中,该M个编码单元可以被划分为多个编码单元组合,其中,任意一个编 码单元组合可以包括该M个编码单元中的部分或全部编码单元,该多个编码单元组合中的任意两个编码单元组合之间的交集为空集,或者说,该多个编码单元组合中的任意两个编码单元组合之间至少存在一个不同的编码单元。并且,可以通过对任意一个编码单元组合进行解码,能够获得数据#A。
其后,发送设备可以从为URLLC业务(即,第二业务的一例)预留的时频资源(或者说,候选时频资源)中,确定用于承载上述多个编码单元组合的任意一个编码单元组合(以下,为了便于理解和区分,记做,编码单元组合#A,即,该编码单元组合#A包括M个编码单元中的部分或全部编码单元)的时频资源,并发送编码单元组合#A。或者说,发送设备可以向接收设备发送上述无限长的码字序列中的部分码字(或者说,子码字序列)直至接收到接收设备反馈的确认消息。
另外,可选地,该方法还包括:
发送设备采用第二编码方式,通过第三时频资源发送第一业务的第三数据,该第三时频资源属于为第二业务预留的时频资源。
接收设备采用第二编码方式,通过第三时频资源接收第一业务的第三数据,该第三时频资源属于为第二业务预留的时频资源。
具体地说,在本申请中,当发送设备和接收设备可以确定无需传输URLLC业务时,发送设备也可以采用编码方式B在为URLLC业务预留的时频资源上发送eMBB业务的数据。
相应地,在本申请中,在发送设备和接收设备使用编码方式#A在为URLLC业务预留的时频资源上传输eMBB业务的数据之前,发送设备和接收设备还可以首先确定是否会在为URLLC业务预留的时频资源上传输URLLC业务的数据。
如果判定为是,则发送设备和接收设备可以使用编码方式#A在为URLLC业务预留的时频资源上传输eMBB业务的数据。
如果判定为否,则发送设备和接收设备可以使用编码方式#B在为URLLC业务预留的时频资源上传输eMBB业务的数据。
即,在为第二业务预留的时频资源上发送第一业务的数据时除了第一编码方式外,还可以使用其他编码方式,例如,上述第二编码方式。从而,可以在判定需要在为第二业务预留的时频资源上需要传输该第二业务的数据时,使用第一编码方式在为第二业务预留的时频资源上发送第一业务的数据,并且,可以在判定不需要在为第二业务预留的时频资源上需要传输该第二业务的数据时,使用其他编码方式(例如,第二编码方式)在为第二业务预留的时频资源上发送第一业务的数据,从而能够减少对传输资源的开销,提高传输效率。
