Definitions

  • the present invention relates to the field of communications, and more particularly to an encoding method, apparatus, base station, and user equipment.
  • Polar Code is an encoding technology that has received increasing attention in recent years. It constructs a composite channel and changes the original channel characteristics, so that the capacity of the composite channel is closer to the high and low poles, so it is called "polar code". Due to this characteristic, the polar code can be adapted to the randomly distributed original channel by a suitable coding design, and achieves good performance and approaches the channel capacity under many different channel implementations. Moreover, it can eliminate decoding by interference, greatly reducing the complexity of the receiver, and is very advantageous for implementation.
  • the channel coding mainly uses a convolutional code and a turbo code, and the code rate is fixed to 1/3, that is, the ratio of the number of input and output bits of the channel coding is equal to 1:3.
  • the number of input bits is determined by the size of the data block to be transmitted, which varies with actual demand, and the number of output bits is related to the size of the physical resource block, which varies with the scheduling result. Therefore, the ratio of input and output bits of the system varies. In the LTE standard, this ratio change is achieved by puncturing the appropriate number of output bits after channel coding, ie by tailoring the number of output bits to achieve bit rate matching.
  • the blocking method is generally: according to the maximum number of input bits L supported by the channel coding, a part of bits not exceeding L is continuously intercepted from the transport block as one code block (data block) until the remaining number of bits is less than L. For a specific blocking method, it is also necessary to add a CRC check bit for each code block (data block), a padding bit for matching the resource block size, and the like, and perform appropriate fine adjustment.
  • the code rate is related to the number of input bits, and it is not suitable to adopt the fixed code rate; the effective input bits and the number of effective output bits are related to the encoder structure. Correlation, and therefore not suitable for rate matching by simply puncturing the output bits.
  • the characteristics of the polar code are different from the convolutional code and the turbo code, and the transmission of each input bit There are significant differences in quality, and the roles of the individual output bits are also different. Therefore, if the transport block is partitioned by the existing method, the coding capability of the polar code will not be fully utilized.

Description

编码方法、装置、基站和用户设备 技术领域
本发明涉及通信领域,并且更具体地,涉及一种编码方法、装置、基站和用户设备。
背景技术
极性码(Polar Code)是一种近年来日益受到重视的编码技术。它通过构造复合信道,改变原始信道特性,使得复合信道的容量更多地接近高、低两极,故称为“极性码”。由于这种特性,极性码通过合适的编码设计,可以适合随机分布的原始信道,在很多不同的信道实现下,均达到很好的性能,并逼近信道容量。而且,它可以通过干扰消除译码,极大地降低接收机复杂度,非常有利于实现。
在现有的LTE标准中,信道编码采用的主要是卷积码和Turbo码,其码率固定为1/3,即:信道编码的输入、输出比特数量之比,等于1:3。在实际传输中,输入比特的数量决定于待传输的数据块大小,随着实际需求而变化,而输出比特的数量则与物理资源块的大小有关,随着调度结果而变化。因此,系统的输入、输出比特的比例是变化的。在LTE标准中,这个比例的变化,是通过在信道编码之后,对适当数量的输出比特进行凿孔而实现,即:通过对输出比特数量进行裁剪,来实现比特速率匹配。
当待发送的传输块较大,超过一个信道编码所能够支持的输入比特数量时,需要将其分割为多个码块(数据块),分别进行信道编码。分块方法大体是:根据信道编码所支持的最大输入比特数量L,从传输块中不断截取出不超过L的一部分比特,作为一个码块(数据块),直至剩余的比特数量小于L为止。具体的分块方法,还需要考虑到对每个码块(数据块)补充CRC校验比特、为匹配资源块大小而补充填充比特等,进行适当微调。
极性码因其结构与卷积码、Turbo码不同,码率与输入比特数量有关,不适合采用固定码率;其有效输入比特、有效输出比特的数量,又都与编码器结构有关,互相关联,因此也不适合通过单纯地对输出比特进行凿孔来实现速率匹配。
同时,极性码的特性与卷积码、Turbo码不同,其各个输入比特的传输 质量存在明显的差异,各个输出比特的作用也存在差异。因此,如果采用现有方法对传输块进行分块,将不能充分地利用极性码的编码能力。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,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,都属于本发明保护的范围。
本发明的技术方案,可以应用于各种通信系统,例如:全球移动通讯系统(GSM,Global System of Mobile communication),码分多址(CDMA,Code Division Multiple Access)系统,宽带码分多址(WCDMA,Wideband  Code Division Multiple Access Wireless),通用分组无线业务(GPRS,General Packet Radio Service),长期演进(LTE,Long Term Evolution)等。
用户端(UE,User Equipment),也可称之为移动终端(Mobile Terminal)、移动用户设备等,可以经无线接入网(例如,RAN,Radio Access Network)与一个或多个核心网进行通信,用户设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。
基站,可以是GSM或CDMA中的基站(BTS,Base Transceiver Station),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNB或e-NodeB,evolutional Node B),本发明并不限定,但为描述方便,下述实施例以eNB为例进行说明。
调制阶数(Modulation Order):一个调制符号所传输的比特数。比如正交相位调制(Quadrature Phase Shift Keying,QPSK)的调制阶数为2,64正交幅度调制(Quadrature Amplitude Modulation,QAM)的调制阶数为6。
在对传输块进行编码时,如果当待发送的传输块较大,超过一个信道编码所能够支持的输入比特数量时,需要将其分割为多个码块(数据块),分别进行信道编码。现有的分块方法大体是:根据信道编码所支持的最大输入比特数量L,从传输块中不断截取出不超过L的一部分比特,作为一个码块(数据块),直至剩余的比特数量小于L为止。具体的分块方法,还需要考虑到对每个码块(数据块)补充循环冗余校验(Cyclical Redundancy Check,CRC)校验比特、为匹配资源块大小而补充填充比特等,进行适当微调。
极性码因其结构与卷积码、Turbo码不同,码率与输入比特数量有关,不适合采用固定码率;其有效输入比特、有效输出比特的数量,又都与编码器结构有关,互相关联,因此也不适合通过单纯地对输出比特进行凿孔来实现速率匹配。
同时,极性码的特性与卷积码、Turbo码不同,其各个输入比特的传输质量存在明显的差异,各个输出比特的作用也存在差异。因此,如果采用现有方法对传输块进行分块,将不能充分地利用极性码的编码能力。
例如,当传输块大小刚好超过极性码所支持的最大有效输入比特数量L时,将会被分割为一个很大的码块(数据块)、一个很小的码块(数据块)。 对于前者,极性码需要使用大量复合信道不太好的输入端口进行传输;而对于后者,极性码有大量复合信道很好的输入端口需要填充无效比特,能力得不到充分利用。
本发明实施例的编码方法、装置、基站和用户设备,能够充分利用polar码的能力,提高polar编码的性能和效率。
图1是本发明实施例的编码方法流程图。图1的方法由编码装置执行。该方法包括:
101,确定用于编码待传输数据块的极性码的数量和该用于编码待传输数据块的极性码中每个极性码的块长度。
应理解,本发明实施例中,polar的块长度(Block Length),等于polar码的输出比特在未凿孔之前总的比特数。极性码的块长度N可以描述成2^n的形式,其中,n为正整数。
polar码的输入比特中,可包括信息比特K、填充比特T和固定比特G。信息比特也称为有效输入比特,固定比特也称为休眠比特。其中,T的取值可能为0。K、T、G和N之间的关系可用以下公式表示:
N=K+T+G。
此外,polar码的输出比特中,可包括编码比特B和凿孔比特Z,编码比特也称为有效输出比特。其中,B、Z和N之间的关系可用以下公式表示:
N=B+Z。
102,根据该待传输数据块的比特数,该用于编码待传输数据块的polar码中每个polar码的块长度,以及该用于编码待传输数据块的polar码中每个polar码内的各个输入比特位置对应的输入复合信道特性,确定该用于编码待传输数据块的polar码中每个polar码的有效输入比特分配信息。
其中,该用于编码待传输数据块的polar码的数量不少于两个,该待传输数据块的比特数超过该用于编码待传输数据块的polar码中任一个polar码所能支持的输入比特数。
应理解,polar码的有效输入比特分配信息,可包括polar码中有效输入比特的数量和\或polar码中有效输入比特的位置。
本发明实施例中,用于编码该待传输数据块的polar码中所有有效输入比特的总数等于该待传输数据块的大小(转换为以比特为单位后的大小)。
本发明实施例中,在采用多个polar码传输数据时,通过根据polar码的 输入比特位置对应的输入复合信道的特性选择多个Polar码的所有输入比特位置中输入复合信道特性较优的输入比特位置作为信息比特位,从而能够获得较优的编码性能。
可选地,作为一个实施例,该方法还包括:接收对端节点发送的资源指配信息,该资源指配信息携带该用于编码待传输数据块的polar码的数量和该用于编码待传输数据块的polar码中每个polar码的块长度的信息;此时,步骤101具体实现为:根据该资源指配信息确定该用于编码待传输数据块的polar码的数量和该用于编码待传输数据块的polar码中每个polar码的块长度的信息。应理解,本发明实施例中,对端节点为与该编码装置所在设备通信的节点。例如,当编码装置位于基站时,对端节点可以是UE、基站下管辖的中继、微基站等等;当编码装置位于UE时,该对端节点可以是UE所属小区的宏基站或微基站,等等。

下面,将结合具体的实施例,对本发明实施例的方法作进一步的描述。
图3是本发明实施例采用多个polar码编码传输数据的交互方法流程图。图3中,BS通过采用向UE发送消息的方法来指定用于编码待传输数据块的polar码的数量和用于编码待传输数据块的polar码中每个polar码的块长度。本发明实施例中,UE采用多个polar码对待传输数据块进行编码。
当然,应理解,在具体的应用中,基站侧也可采用多个polar码对待传输数据块进行编码,本发明实施例以UE侧进行举例说明。
301,BS发送资源指配信令。
其中,该资源指配信令中可用于通知UE进行数据传输所使用的物理资源、用于编码待传输数据块的Polar码的数量、用于编码待传输数据块的polar码中每个Polar码的块长度、调制编码配置(Modulation and Coding Scheme,MCS)等信息。
例如,某一个具体的资源指配信令可以指示,物理资源包含了频域4个子带、时域10个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,采用64正交幅度调制(Quadrature Amplitude Modulation,QAM)星座调制,Polar码数量为2,块长度分别为16384、4096。
若系统配置为每个子带包含5个RB,约定每个RB包含12个子载波,则该信令指示了4*5*12*10=2400个RE资源。
302,UE确定极性码的数量和块长度。
UE可根据信令中的携带的polar码信息,确定用于编码待传输数据块的Polar码的数量和用于编码待传输数据块的polar码中每个Polar码的块长度。根据步骤301中的资源指配信令的例子,可确定Polar码数量为2,块长度分别为16384、4096。
303,UE确定各个极性码的有效输入比特分配信息。
UE可根据信令中的MCS指示、子带数指示等,通过查询预设的映射表,确定待传输数据块的传输块大小(Transport Block Size,TBS)。在本实施例中,假设TBS=10000。
假设根据预先约定,每个传输块(Transport Block,TB)、每个数据块分别要加24比特的循环冗余校验(Cyclic Redundancy Check,CRC),则待传输的总比特数为:TBS+24+2*24=10072。
此外,UE还可根据每个polar码的每个输入比特位置所对应的输入复合信道特性来确定如何分配有效输入比特。不妨用第一参数来表征输入比特位置所对应的输入复合信道特性。该第一参数可用于表示polar码的输入比特位置对应的输入复合信道质量。具体地,该第一参数可包括以下至少一种:输入复合信道的容量,输入复合信道的错误概率,输入复合信道对应的位置指标。其中,该输出复合信道对应的位置指标根据所属的polar码对应的参数方程及该输出复合信道对应的输处比特位置计算得到;或者,该输出复合信道对应的位置指标根据所属的polar码对应的指标映射表及该输出复合信道对应的输处比特位置查表得到。其中,该指标映射表用于表示polar码的输入比特位置与输入复合信道对应的位置指标之间的映射关系。
应理解,当第一参数所表示的内容不同时,其所表示的输入复合信道的特性也不同。例如,当第一参数为polar码的输入复合信道的容量时,第一参数越大,输入复合信道质量越好;当第一参数为polar码的错误概率时,第一参数越大,输入复合信道质量越差。UE在确定有效输入比特的分配信息时,可根据第一参数进行排序,将有效输入比特分配到输入复合信道特性较好的输入比特位置上。
本发明实施例采用输出复合信道对应的位置指标作为第一参数来表示 输入复合信道的质量。其中,输出复合信道对应的位置指标越大,输入复合信道的质量越好。
此处假设BS和UE双方事先约定采用预设的映射表来确定每个Polar码的每个输入比特位置所对应的输入复合信道特性(第一参数)。一种预设的映射表,是对每一种Polar码的块长度,分别定义一个表格,给出其各个输入比特位置对应的第一参数。如果对于某一种Polar码的块长度,存在多种不同的结构配置,那么该映射表可以该处每种Polar码的块长度在每种可能的结构配置下的各个输入比特位置对应的第一参数。
据此约定,通过查表,确定polar码的块长度为16384的Polar码的各输入比特(假设有9000个)位置对应的第一参数、polar码的块长度为4096的Polar码的各输入比特(假设有2000个)位置对应的第一参数。然后从这11000个输入比特位置中,取第一参数最大的10072个,作为传输采用的输入比特位置;或者等效地,取第一参数最小的11000-10072=28个,作为填充比特位置。假设在这10072个输入比特位置中,有700个属于大小为16384的Polar码、372个属于大小为4096的Polar码,则由此可以确定,这两个Polar码的有效输入比特数分别为700、372。
304,UE确定各个极性码的有效输出比特分配信息。
如步骤303所述,UE根据资源指配信令,可以确定出传输采用的RE数量为2400。进一步,可以结合MCS指示,确定所有Polar码的总输出比特数。在本实施例中,信令指示了64QAM,因此2个Polar码的总输出比特数为2400*6=14400。
类似地,UE还可根据每个polar码的每个输出比特位置所对应的输出复合信道特性来确定如何分配有效输出比特。不妨用第二参数来表征输出比特位置所对应的输出复合信道特性。该第二参数可用于表示polar码的输出比特位置对应的输出复合信道质量。具体地,该第二参数可包括以下至少一种:输出复合信道的容量,输出复合信道的错误概率,输出复合信道对应的位置指标。其中,该输出复合信道对应的位置指标根据所属的polar码对应的参数方程及该输出复合信道对应的输处比特位置计算得到;或者,该输出复合信道对应的位置指标根据所属的polar码对应的指标映射表及该输出复合信道对应的输处比特位置查表得到。其中,该指标映射表用于表示polar码的输出比特位置与输出复合信道对应的位置指标之间的映射关系。
此处假设BS和UE双方事先约定采用预设的映射表来确定每个Polar码的每个输出比特位置所对应的输出复合信道特性(第二参数)。一种预设的映射表,是对每一种Polar码的块长度,分别定义一个表格,给出其各个输出比特位置的第二参数。如果对于某一种Polar码的块长度,存在多种不同的结构配置,那么该映射表可以该处每种Polar码的块长度在每种可能的结构配置下的各个输出比特位置对应的第二参数。
据此约定,通过查表,确定polar码大小为16384的Polar码的各输入比特(假设有10000个)位置对应的第二参数、大小为4096的Polar码的各输入比特(假设有2500个)位置对应的第二参数。然后从这12500个输入比特位置中,取第二参数最大的14400个,作为提取Polar码有效输出比特的位置;或者等效地,取第二参数最小的16384+4096-14400=6080个,作为凿孔比特位置。假设在这14400个输出比特位置中,有11000个属于大小为16384的Polar码、3400个属于大小为4096的Polar码,则由此可以确定,这两个Polar码的有效输出比特数分别为11000、3400。
当然,应理解,本发明实施例中,BS和UE也可采用预先约定的算法,根据待传输数据块的总比特数确定用于编码待传输数据块的polar码的数量和块长度。
图4是本发明实施例采用多个polar码编码传输数据的交互方法流程图。图4中,BS通过采用和UE预先约定方法的方式来指定polar码的数量和大小信息。本发明实施例中,UE采用多个polar码对待传输数据块进行编码。
当然,应理解,在具体的应用中,基站侧也可采用多个polar码对待传输数据块进行编码,本发明实施例以UE侧进行举例说明。
401,BS发送资源指配信令。
其中,该资源指配信令中可用于通知UE进行数据传输所使用的物理资源、调制编码配置(Modulation and Coding Scheme,MCS)等信息。
例如,某一个具体的资源指配信令可以指示,物理资源包含了频域4个子带、时域10个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,采用64正交幅度调制(Quadrature Amplitude Modulation,QAM)星座调制。
若系统配置为每个子带包含5个RB,约定每个RB包含12个子载波,则该信令指示了4*5*12*10=2400个RE资源。
402,UE确定极性码的数量和块长度。
UE根据该资源指配信息,可以推知传输块的大小TBS。比如一种推知的方法是,双方约定一个映射表,根据MCS指示、物理资源指示等参数,通过查表确定TBS。在本实施例中,假设TBS=10000。
约定每个CRC的长度为24,要求每个码块的大小CBS<=6000,双方约定确定Polar码数量的算法为:N_polar=ceil[(TBS+24)/(6000-24)],则可以据此算法确定出Polar码的数量为2,即分为2个数据块。
假设双方约定确定Polar码的块长度的方法为:各Polar码的块长度相同,为满足物理资源要求的最小的2的整次幂,则可以据此方法确定每个Polar码的大小为:
Figure PCTCN2015075700-appb-000001
403,UE确定各个极性码的有效输入比特分配信息。
假设根据预先约定,每个TB、每个数据块分别要加24比特的CRC,则待传输的总比特数为:TBS+24+2*24=10072。
假设双方约定,第一预定阈值取值为50,则将待传输的所有比特近似均匀地分配到各Polar码,各Polar码的输入比特数的差异小于等于50,且须在满足Polar码的输入比特数要求的前提下,最小化填充比特总数。该要求可以通过表格或公式进行约定,在这里以公式为例,约定Polar码的输入比特数可以为50*k,其中k为小于等于120的自然数。则双方可以据此约定,确定两个Polar码的输入比特数都为5050,总的填充比特数为28。容易约定,当各Polar码的块长度相同,输入比特数也相等时,其有效输入比特数也应相等。则据此可以确定,这两个Polar码的有效输入比特数都为5036,填充比特数都为14。
在这个例子中,两个Polar码的输入比特数刚好相等。实际上,也有可能出现不等的情况。例如,当TBS=10070时,待传输的总比特数为10142:按照上述约定的方法,得到的两个Polar码的输入比特数将分别为5050、5100,总的填充比特数为8。可以约定,当各Polar码的块长度相同,输入比特数不等时,首先令各较小的Polar码的有效输入比特数等于其输入比特数(无填充比特),然后将剩余的有效输入比特数对各较大的Polar码均匀分配。据此可以确定,这两个Polar码的有效输入比特数分别为5050、5092,填充比特数分别为0、8。
双方可以约定,将有效输入比特映射到(在本实施例中是5036个)输 入复合信道质量相对较好的位置,或者等效地,将休眠比特和填充比特映射到(本实施例中是8192-5036=3156个)输入复合信道相对较差的位置。
根据经验公式,当第一预定阈值取值为polar码的所有调制阶数最大值的5倍时,能够取得较好的编码性能。
404,UE确定各个极性码的有效输出比特分配信息。
如步骤403所述,UE根据资源指配信令,可以确定出传输采用的RE数量为2400。进一步,可以结合MCS指示,确定所有Polar码的总输出比特数。在本实施例中,信令指示了64QAM,因此2个Polar码的总输出比特数为2400*6=14400。
假设双方约定,第二预定阈值取值为50,将有效输出比特按照有效输入比特的分配比例,分配到各Polar码。此时,这两个Polar码的有效输入比特数相等,所以其有效输出比特数也相等,都为7200(50*144),其凿孔比特数都为8192-7200=992。
双方可以约定,将有效输出比特映射到(在本实施例中是7200个)输出复合信道质量相对较好的位置,或者等效地,将凿孔比特映射到(本实施例中是992个)输出复合信道相对较差的位置。
根据经验公式,当第二预定阈值取值为polar码的所有调制阶数最大值的6倍时,能够取得较好的编码性能。
当然,应理解,本发明实施例中,BS也可通过向UE发送资源指配信令指定polar码的数量和块长度。
此外,应理解,图3和图4中,确定有效输入比特分配信息和确定有效输出比特分配信息的方法可以相互独立。
例如,在确定有效输入比特分配信息,采用图3的步骤303所示的方法或图4的步骤403所示的方法,而在确定有效输出比特分配信息,可参照现有技术的方案执行。此时,能够对polar码的编码输入性能实现一定程度的改善。
又例如,在确定有效输入比特分配信息时,可参照现有技术的方案执行,而在确定有效输出比特分配信息时,采用图3的步骤304所示的方法或图4的步骤404所示的方法。此时,能够对polar码的编码输出性能实现一定程度的改善。
