Description

传输信息的方法、终端设备、网络设备和装置 技术领域
本发明涉及无线通信技术领域，具体地，涉及传输信息的方法、终端设备、网络设备和装置。
背景技术
稀疏性的非正交多址接入方式是一种新的多址接入方式。在该接入方式中，多个用户使用同一个时频资源块。每个资源块由若干资源单元(RE，Resource Element)组成，RE可以是正交频分复用(OFDM，Orthogonal Frequency Division Multiplex)技术中的子载波-符号单元，也可以是其他空口技术中时域或频域的资源单元。
稀疏性的非正交多址接入系统与OFDM系统相似，仅将OFDM系统中的调制编码器和调制解码器替换成稀疏性的非正交多址接入对应的编码器和译码器。在长期演进(LTE，Long Term Evolution)系统中，若译码端译码失败，则采用混合自动请求重传(HARQ，Hybrid Automatic Repeat Request)系统再次发送译码错误数据。HARQ系统即为在自动请求重传系统中引入了前向纠错码(FEC，Forward Error Correction)，该FEC可以用来纠正传输过程中的数据差错。如果数据差错在FEC的纠错范围内，则FEC进行纠错，译码端反馈混合自动请求重传确认应答(HARQ-ACK，HARQ Acknowledgement)信息给发送端；如果数据差错超出了FEC的纠错范围，则译码端反馈混合自动请求重传否定应答(HARQ-NACK，HARQ Negative Acknowledgement)信息给发送端。其中，HARQ-ACK和HARQ-NACK统称为HARQ信息。
现有的LTE系统，在物理上行共享信道(PUSCH，Physical Uplink Shared Channel)内，用户设备在各自的频带内实现HARQ信息和上行传输数据的复用，该HARQ信息的传输方法适用于无频域复用的系统。但是，对于某些系统，例如SCMA系统，该类系统中多个用户在频域上是复用的。若HARQ信息的传输采用LTE系统中的方法则导致各个用户的HARQ信息会发生重叠，基站采用LTE的译码方法则无法进行译码。因此，对于多个用户复用频域的系统，现有的在PUSCH信道中传输HARQ信息的方法不再适用。

被设计用于通信的每组天线和/或区域称为网络侧设备102的扇区。例如，可将天线组设计为与网络侧设备102覆盖区域的扇区中的终端设备通信。在网络侧设备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，网络侧设备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，与网络侧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，在网络侧设备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，网络侧设备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。
为便于理解，下面将对LTE系统中传输HARQ信息的方法进行描述。
在LTE系统的PUSCH信道中，终端设备与网络设备之间传输HARQ信息。网络设备向终端设备传输信息，若数据的传输错误在FEC的纠错范围内，终端设备能够正确译码，则终端设备反馈HARQ-ACK信息给网络设备；若数据的传输错误不在FEC的纠错范围内，终端设备不能够正确译码，则终端设备反馈HARQ-NACK信息给网络设备。
当在PUSCH信道上传输HARQ信息时，该HARQ信息需要先进行编码。HARQ信息可以包括HARQ-ACK信息和HARQ-NACK信息。具体的对于HARQ信息中的HARQ-ACK信息的编码方式可以如下：
若HARQ-ACK信息包含1比特
Figure PCTCN2015074622-appb-000001
根据表1进行编码；若HARQ-ACK信息包含2比特
Figure PCTCN2015074622-appb-000002
根据表2进行编码。
表1
Figure PCTCN2015074622-appb-000003
表2
Figure PCTCN2015074622-appb-000004
其中，
Figure PCTCN2015074622-appb-000005
Qm表示调制阶数，可以表示为在星座调制的时候将包括Qm个比特的一个调制符号映射到一个时频资源上去。x和y表示占位符，用于拉大承载了HARQ-ACK信息或HARQ-NACK信息的调制符号间的距离，以提高译码率。
编码后的HARQ信息还需要根据其传输模式决定是否需要加扰、上变频等其他计算，但总的编码长度不变。设HARQ信息进行比特编码后得到编码后的HARQ信息，终端设备进而对该编码后的HARQ信息进行调制和映射处理。第一步骤，将编码后的HARQ信息进行星座调制成HARQ调制符号。第二步骤，将HARQ调制符号映射到分配的时频资源上去。
在第一步骤中，终端设备可以将1比特的HARQ信息进行编码，得到编码后的HARQ信息，编码长度为Qm个比特，再对编码后的HARQ信息进行星座调制后为1个调制符号；终端设备可以将2比特的HARQ信息进行编码，得到编码后的HARQ信息，编码长度为3*Qm个比特，再对编码后的HARQ信息进行星座调制后为3个调制符号。
在第二步骤中，终端设备可以按照如下规则将调制符号映射到分配的时频资源上去：例如，在一个子帧的两个时隙中，均有HARQ调制符号，并且HARQ调制符号可以映射在解调参考信号(DMRS，Demodulation reference signal)的调制符号的一侧或两侧。
具体地，该映射的顺序可以是在一个子帧的两个时隙中，分别映射解调导频DMRS，即每个时隙可以映射一个DMRS。然后，在剩余的时频资源上映射比特编码后的上行数据，最后按照复用规则将HARQ调制符号依次映射到DMRS两侧。
上述为LTE系统中如何传输HARQ信息的方法。
稀疏码多址接入(SCMA，Sparse Code Multiple Access)是一种非正交的多址接入技术，当然本领域技术人员也可以不把这个技术称之为SCMA，也可以称为其他技术名称。该技术借助码本在相同的传输资源上传输多个不 同的数据流，其中不同的数据流使用的码本不同，从而达到提升资源的利用率。数据流可以来自同一个终端设备也可以来自不同的终端设备。但是，在SCMA系统中终端设备使用同一时频资源，上述传输HARQ信息的方法会导致每个终端设备的HARQ调制符号重叠在一起而无法进行解调。为解决此问题，本发明实施例提出一种传输信息的方法和终端设备，能够准确传输HARQ信息，提高传输的可靠性。
图2是本发明一个实施例的传输信息的方法的示意性流程图。该方法200可以由终端设备执行，该如图2所示，该方法200包括：
S210，终端设备根据码本对编码后的混合自动请求重传HARQ信息进行调制，以生成HARQ调制符号，HARQ调制符号包括至少一个非零HARQ调制符号和一个零HARQ调制符号，码本包括至少两个码字，码字为多维复数向量，码字用于表示比特与至少两个调制符号之间的映射关系；
S220，向网络设备发送HARQ调制符号。
本发明实施例中，通过根据码本对编码后的HARQ信息的进行调制，使得多个终端设备使用同一时频资源进行HARQ信息传输时，能够在网络设备侧进行正确译码。因此，本发明实施例能够在多个终端设备使用同一时频资源的系统中传输HARQ信息，提高传输信息的可靠性。
具体地，作为上述同一时频资源，例如，在以资源单元(RE，Resource Element)为单位的时频资源划分方式下，上述时频资源可以是由多个RE组成的时频资源块(也可以称为时频资源组)，并且，该多个RE可以是在时域上的位置相同(即，对应相同的符号)且在频域上的位置相异(即，对应不同子的载波)，或者，该多个RE可以是在时域上的位置相异(即，对应不同的符号)且在频域上的位置相同(即，对应相同的子载波)，本发明并未特别限定。
可选地，该调制为通过码字进行的调制，该码字为多维复数向量，用于表示编码后的HARQ信息与至少两个调制符号之间的映射关系，映射关系可以理解为直接映射关系，该至少两个调制符号包括至少一个零调制符号和至少一个非零调制符号。
可选地，该终端设备根据码本对编码后的HARQ信息进行调制，包括：
终端设备以稀疏码分多址SCMA方式，对编码后的HARQ信息进行调制处理。
具体地，稀疏码多址接入(SCMA，Sparse Code Multiple Access)是一种非正交的多址接入技术，当然本领域技术人员也可以不把这个技术称之为SCMA，也可以称为其他技术名称。该技术借助码本在相同的传输资源上传输多个不同的数据流，其中不同的数据流使用的码本不同，从而达到提升资源的利用率。数据流可以来自同一个终端设备也可以来自不同的终端设备。
SCMA采用的码本为两个或两个以上码字的集合，同一个码本的码字可以互不相同。
其中，码字可以为多维复数域向量，其维数为两维或两维以上，用于表示数据与两个或两个以上调制符号之间的映射关系，该调制符号包括至少一个零调制符号和至少一个非零调制符号，数据可以为二进制比特数据或者多元数据可选的，零调制符号和非零调制符号的关系可以为零调制符号个数不少于非零调制符号个数。
码本由两个或两个以上的码字组成。码本可以表示一定长度的数据的可能的数据组合与码本中码字的映射关系,映射关系可以是直接的映射关系。
SCMA技术通过将数据流中的数据按照一定的映射关系直接映射为码本中的码字即多维复数向量，实现数据在多个资源单元上的扩展发送。这里的数据可以是二进制比特数据也可以是多元数据，多个资源单元可以是时域、频域、空域、时频域、时空域、时频空域的资源单元。
文中的特征序列与码本相对应，由零元素和1元素组成，零元素表示所对应的码本中码字在该零元素相应位置的元素全为零，1元素表示所对应的码本中码字在该1元素相应位置的元素不全为零或全不为零。两个或两个以上的特征序列组成特征矩阵。应理解，SCMA只是一个名称，业界也可以用其他名称来表示该技术。
SCMA采用的码字可以具有一定稀疏性，比如说码字中的零元素数量可以不少于调制符号数量，以便于接收端可以利用多用户检测技术来进行较低复杂度的译码。这里，以上列举的零元素数量与调制符号的关系仅为稀疏性一个示例性说明，本发明并不限定于此，零元素数量与非零元素数量的比例可以根据需要任意设定。
作为上述通信系统100的一例，可以列举该SCMA系统，在该系统100中，多个用户复用同一个时频资源块进行数据传输。每个资源块由若干资源RE组成，这里的RE可以是OFDM技术中的子载波-符号单元，也可以是其 它空口技术中时域或频域的资源单元。例如，在一个包含L个终端设备的SCMA系统中，可用资源分成若干正交的时频资源块，每个资源块含有U个RE，其中，该U个RE可以是在时域上的位置相同。当终端设备#L发送数据时，首先将待发送数据分成S比特大小的数据块，通过查找码本(由网络设备确定并下发给该终端设备)将每个数据块映射成一组包括U个调制符号的调制符号序列X#L＝{X#L1，X#L2，…，X#LU}，序列中的每个调制符号对应资源块中一个RE，然后根据调制符号生成信号波形。对于S比特大小的数据块，每个码本含有2S个不同的调制符号组，对应2S种可能的数据块。
上述码本也可以称为SCMA码本是SCMA码字集合，SCMA码字是一种信息比特到调制符号的映射关系。即，SCMA码本为上述映射关系的集合。
另外，在SCMA中，每个终端设备所对应的组调制符号X#k＝{X#k1，X#k2，…，X#kL}中，至少一个符号为零符号，并且，至少一个符号为非零符号。即，针对一个终端设备的数据，在L个RE中，只有部分RE(至少一个RE)承载有该终端设备的数据。
图3示出了以6个数据流复用4个资源单元作为举例的SCMA的比特映射处理(或者说，编码处理)的示意图，该示意图为二分图。如图3所示，6个数据流组成一个分组，4个资源单元组成一个编码单元。一个资源单元可以为一个子载波，或者为一个RE，或者为一个天线端口。
在图3中，数据流和资源单元之间有连线表示至少存在该数据流的一种数据组合经码字映射后会在该资源单元上发送非零的调制符号，而数据流和资源单元之间没有连线则表示该数据流的所有可能的数据组合经码字映射后在该资源单元上发送的调制符号都为零。数据流的数据组合可以按照如下阐述进行理解，例如，二进制比特数据流中，00、01、10、11为所有可能的两比特数据组合。
为了描述方便，用s1至s6依次表示图3中6个数据流待发送的数据组合，用x1至x4依次表示图3中4个资源单元上发送的符号。数据流和资源单元之间的连线表示该数据流的数据经扩展后会在该资源单元上发送调制符号，其中，该调制符号可以为零调制符号(与零元素相对应)，也可以为非零调制符号(与非零元素相对应)，数据流和资源单元之间没有连线则表示该数据流的数据经扩展后不会在该资源单元上发送调制符号。
从图3中可以看出，每个数据流的数据经码字映射后会在两个或两个以 上的资源单元上发送调制符号，同时，每个资源单元发送的符号是来自两个或两个以上的数据流的数据经各自码字映射后的调制符号的叠加。例如数据流3的待发送数据组合s3经码字映射后可能会在资源单元1和资源单元2上发送非零的调制符号，而资源单元3发送的数据x3是数据流2、数据流4和数据流6的待发送数据组合s2、s4和s6分别经各自码字映射后得到的非零调制符号的叠加。由于数据流的数量可以大于资源单元的数量，因而该SCMA系统可以有效地提升网络容量，包括系统的可接入用户数和频谱效率等。
结合以上关于码本和图3的描述，码本中的码字通常具有如下形式：
Figure PCTCN2015074622-appb-000006
而且，相对应的码本通常具有如下形式：
Figure PCTCN2015074622-appb-000007
其中，N为大于1的正整数，可以表示为一个编码单元所包含的资源单元数量，也可以理解为码字的长度；Qm为大于1的正整数，表示码本中包含的码字数量，可以理解为调制阶数，当然本领域技术人员可以叫做其他名称,例如4阶调制时Qm为4；q正整数，且1≤q≤Qm；码本和码字所包含的元素cn,q为复数，cn,q数学上可以表示为：
cn,q∈{0,α*exp(j*β)},1≤n≤N,1≤q≤Qm
α和β可以为任意实数，N和Qm可以为正整数。
码本中的码字可以和数据形成一定映射关系，例如码本中的码字可以与二进制数据流的两比特数据组合形成如下映射关系。
例如，“00”可以对应码字1，即
Figure PCTCN2015074622-appb-000008
“01”可以对应码字2，即
Figure PCTCN2015074622-appb-000009
“10”可以对应码字3，即
Figure PCTCN2015074622-appb-000010
“11”可以对应码字4，即
Figure PCTCN2015074622-appb-000011
结合上述图3，当数据流与资源单元之间有连线时，数据流对应的码本和码本中的码字应具有如下特点：码本中至少存在一个码字在相应的资源单元上发送非零的调制符号，例如，数据流3和资源单元1之间有连线，则数据流3对应的码本至少有一个码字满足c1,q≠0，1≤q≤Qm；
当数据流与资源单元之间没有连线时，数据流对应的码本和码本中的码字应具有如下特征：码本中所有码字在相应的资源单元上发送为零的调制符号，例如，数据流3和资源单元3之间没有连线，则数据流3对应的码本中的任意码字满足c3,q＝0，1≤q≤Qm。
综上，当调制阶数为4时，上述图3中数据流3对应的码本可以具有如下形式和特征：
Figure PCTCN2015074622-appb-000012
其中，cn,q＝α*exp(j*β),1≤n≤2,1≤q≤4，α和β可以为任意实数，对任意q，1≤q≤4，c1,q和c2,q不同时为零，且至少存在一组q1和q2，1≤q1，q2≤4，使得
Figure PCTCN2015074622-appb-000013
且
Figure PCTCN2015074622-appb-000014
举例地，如果数据流3的数据s3为“10”，则根据前述映射规则，该数据组合映射为码字即4维复数向量：
Figure PCTCN2015074622-appb-000015
进一步地，在SCMA系统中，二分图也可以用特征矩阵来表示。特征矩阵可以具有如下形式：
Figure PCTCN2015074622-appb-000016
其中，rn,m表示该特征矩阵中的元素，m和n为自然数，且1≤n≤N,1≤m≤M，N行分别表示一个编码单元中的N个资源单元，M列分别表示复用的数据流数量。虽然特征矩阵可以用通用的形式表达，但是特征矩阵可以具有如下特征：
(1)特征矩阵中的元素rn,m∈{0,1},1≤n≤N,1≤m≤M，其中，rn,m＝1可以表示以对应的二分图解释，第m个数据流与资源单元n之间有连线，也可以理解该第m个数据流至少存在一种数据组合经码字映射为非零的调制符号；rn,m＝0可以表示以对应的二分图解释，第m个数据流与资源单元n之间没有连线，也可以理解该第m个数据流的所有可能的数据组合经码字都映射为零调制符号；
(2)进一步可选的，特征矩阵中的0元素的数目可以不少于1元素的数目，从而体现稀疏编码的特性。
同时，特征矩阵中的列可以称为特征序列。并且该特征序列可以具有如下表达形式：
Figure PCTCN2015074622-appb-000017
因此，特征矩阵也可以认为是由一系列特征序列组成的矩阵。
结合上述对特征矩阵的特征描述，对于图3中给出的示例，相应的特征矩阵可以表示为：
Figure PCTCN2015074622-appb-000018
而图3中的数据流3使用的码本
Figure PCTCN2015074622-appb-000019
对应的特征序列可以表示为：
Figure PCTCN2015074622-appb-000020
由此可以认为，码本对应特征序列的关系是一对一的关系，即一个码本唯一地对应一个特征序列；而特征序列对应码本的关系可以是一对多的关系，即一个特征序列对应一个或一个以上的码本。因此特征序列可以理解为：特征序列与码本相对应，由零元素和1元素组成，零元素的位置表示所对应的码本中码字在该零元素相应位置的元素全为零，1元素表示所对应的码本中码字在该1元素相应位置的元素不全为零或全不为零。特征序列和码本之间的对应关系可以由以下两个条件确定：
(1)码本中的码字与对应的特征序列具有的总元素数量相同；
(2)对于特征序列中任何一个数值为1的元素位置，都能在对应的码本中至少找到一个码字，使得该码字在相同位置上的元素不为零；对于特征序列中任何一个数值为零的元素位置，对应的码本中所有码字在相同位置上的元素都为零.
还应理解，在SCMA系统中，可以直接表示和存储码本，例如存储上文中的码本或码本中的各个码字，或者仅存储码字中对应特征序列元素为1的位置上的元素等。因而，在应用本发明时，需要假设SCMA系统中的基站和用户设备都可以存储预先设计的以下部分或全部内容：
(1)一个或多个SCMA特征矩阵：
Figure PCTCN2015074622-appb-000021
其中rn,m∈{0,1}，1≤n≤N,1≤m≤M，M和N均为大于1的整数，其中M表示复用的数据流数量，N大于1的正整数，可以表示为一个编码单元所含有的资源单元的数量，也可以理解表示为码字的长度；
(2)一个或多个SCMA特征序列：
Figure PCTCN2015074622-appb-000022
其中1≤m≤M；
(3)一个或多个SCMA码本：
Figure PCTCN2015074622-appb-000023
其中Qm≥2，Qm可以为该码本对应的调制阶数，每个码本可以对应一种调制阶数，其中，N大于1的正整数，可以表示为一个编码单元所含有的资源单元的数量，也可以理解表示为码字的长度。
应理解，以上列举的SCMA系统仅为适用本发明的传输信息的方法和装置的通信系统的一例，本发明并不限定于此，其他的能够使终端设备在同一时段复用相同的时频资源进行传输信息的通信系统均落入本发明的保护范围内。
为了便于理解和说明，在以下实施例中，在未特别说明的情况下，以在该SCMA系统中的应用为例，对本发明实施例的数据处理的方法进行说明。
另外，在本发明实施例中，上述调制的过程可以和现有的SCMA系统中的调制过程类似，这里，为了避免赘述，省略其详细说明。由于SCMA系统对于码本的稀疏性要求，因此，在经S110的调制过程而生成的各终端设备所对应的调制符号序列中共包括U个符号(对应U个RE)，其中的V个符号为非零符号。
为方便描述，本发明实施例中的时频资源可以包括L个资源单元，该L个资源单元RE可以是在时域上的位置相同(即，对应相同的符号)且在频域上的位置相异(即，对应不同子的载波)。
可选地，该调制过程可以为通过码字进行，该码字为多维复数向量，用于表示编码后的HARQ信息与至少两个调制符号之间的映射关系，该至少两个调制符号包括至少一个零调制符号和至少一个非零调制符号。
应理解，本发明实施例中的终端设备可以为需要发送HARQ信息的终端设备。该目标终端设备可以为多个需要发送HARQ信息的终端设备中的任一个，为方便描述，本发明实施例仅对一个目标终端设备进行描述，其他需要发送HARQ信息的终端设备也可以进行相应操作。
可选地，码本可以为目标终端设备从网络设备预先定义的码本集中选择的码本，也可以为网络设备分配给目标终端设备的码本，本发明实施例并不限于此。还应理解，在调制过程中，根据的码本不同，生成的调制符号也不相同。
可选地，本发明实施例中对HARQ信息进行比特编码的方法可以与LTE系统中的比特编码的方法相同，也可以采用其他比特编码的方法，本发明实施例并不限于此。该比特编码的过程可以基于表1和表2进行一步编码，也可以集成在其他操作中完成，直接得到编码后的HARQ信息。
具体地，以HARQ-ACK信息为例，若QACK个HARQ-ACK信息进行比特编码，得到QACK组编码后的HARQ信息
Figure PCTCN2015074622-appb-000024
其中，
Figure PCTCN2015074622-appb-000025
为一组编码后的HARQ信息。
应理解，终端设备向网络设备发送HARQ调制符号时，可以将HARQ调制符号进行映射到分配的时频资源上去。本发明实施例中可以进一步划分为两部分。第一步骤，将编码后的HARQ信息进行调制成HARQ调制符号。第二步骤，将HARQ调制符号映射到分配的时频资源上去。
具体地，若系统中的多个终端共用L个RE时，本发明实施例中在发送HARQ调制符号之前，可以包括：
第一步骤，将编码后的HARQ信息根据码本进行调制成L个HARQ调制符号。QACK组编码后的HARQ信息
Figure PCTCN2015074622-appb-000026
调制后得到的QACK个HARQ调制信息
Figure PCTCN2015074622-appb-000027
其中，Xk＝{Xk,1,Xk,1,...,Xk,L}为按照该用户的码本Ck调制后得到的L个HARQ调制符号。L个HARQ调制符号与L个RE一一对应。
第二步骤，将L个HARQ调制符号映射到分配的时频资源(即L个RE)上。与LTE系统不同的是，L个HARQ调制符号每次映射一个Xk，即每次映射L个HARQ调制符号到对应的L个RE上。应理解，该L个资源单元RE可以是在时域上的位置相同(即，对应相同的符号)且在频域上的位置相异(即，对应不同子的载波)。该映射的规则可以与LTE系统中的映射规则类似，即从最后L行开始映射，对于DMRS两侧的4个符号，依次映射，每次映射到一个符号的L个RE。若还有HARQ调制符号没有映射完成，则向上依次递加L行映射，直到所有HARQ调制符号完成映射。
本发明实施例中，通过根据码本对编码后的HARQ信息的进行调制， 使得多个终端设备使用同一时频资源进行HARQ信息传输时，能够在网络设备侧进行正确译码。因此，本发明实施例能够在多个终端设备使用同一时频资源的系统中传输HARQ信息，提高传输信息的可靠性。
相应地，对于其他需要发送HARQ信息的终端设备，也可以采用上述方法进行调制。本发明实施例仅对其中一个终端设备进行详细描述。
可选地，作为另一实施例，如果调制阶数为K，则编码后的HARQ信息的长度为N×K，其中，K为2的整数倍，N为大于零的正整数,本发明实施例中调制阶数这个名称也可以被称为其他名称,下面不再每个实施例赘述。
具体地，当N＝1时，该比特编码的方法与LTE系统中的上述比特编码的方法相同。当N>1时，该比特编码的方法为一种改进的比特编码方法。下面详细描述该种比特编码方法。
可选地，作为另一实施例，若编码前的HARQ信息的长度为1比特，则N为2。
例如，若HARQ-ACK信息包含1比特
Figure PCTCN2015074622-appb-000028
调制阶数K为2，则编码后得到的HARQ-ACK信息可以为4比特
Figure PCTCN2015074622-appb-000029
即N＝2；调制阶数K为4，则编码后得到的HARQ-ACK信息可以为8比特
Figure PCTCN2015074622-appb-000030
即N＝2；调制阶数K为6，则对HARQ-ACK信息进行编码后得到的HARQ-ACK信息可以为12比特
Figure PCTCN2015074622-appb-000031
即N＝2。
可选地，作为另一实施例，若编码前的HARQ信息的长度为2比特，则N为6。
若HARQ-ACK信息包含2比特
Figure PCTCN2015074622-appb-000032
调制阶数K为2，则对HARQ-ACK信息进行编码后得到的编码后的HARQ-ACK信息可以为12比特
Figure PCTCN2015074622-appb-000033
即N＝6；若调制阶数K为4时，则对HARQ-ACK信息进行编码后得到24比特

即N＝6；若调制阶数K为6时，则对HARQ-ACK信息进行编码后得到36比特
Figure PCTCN2015074622-appb-000035
即N＝6。
与上文中的表1和表2类型，该比特编码的方法可以基于表3和表4进行比特编码。表3为HARQ-ACK信息的长度为1比特时，N为2的情况。 表4为HARQ-ACK信息的长度为2比特时，N为2的情况。

表4
Figure PCTCN2015074622-appb-000037
其中，
Figure PCTCN2015074622-appb-000038
Qm表示调制阶数，即在映射的时候将Qm个比特调制成的一个调制符号映射到一个时频资源上去。x和y表示占位符，用于拉大承载了HARQ-ACK信息或HARQ-NACK信息的调制符号间的距离，以提高译码率。
本发明实施例中的比特编码方法通过重复的信息比特增加编码长度，增加编码冗余量，拉大HARQ-ACK信息比特之间的距离，能够降低编码带来的误差。
应理解，本发明实施例中N的取值可以根据信道环境的好坏，采用不同的编码长度。若信道环境好，可以采用较少的重复次数；若信道环境差，可以增加重复的次数，以保证HARQ-ACK信息的传输可靠性。
图4是本发明另一实施例的传输信息的方法的示意性流程图。该方法400应用于包括至少两个终端设备的通信系统，该至少两个终端设备使用同一时频资源进行信息传输，该方法400包括：
S410，终端设备对编码后的混合自动请求重传HARQ信息进行调制生成HARQ调制符号；
S420，终端设备接收映射资源指示信息，映射资源指示信息用于指示分配给终端设备对HARQ调制符号进行映射的映射资源信息；
S430，终端设备根据映射资源指示信息对HARQ调制符号进行资源映射。
本发明实施例中，通过改变编码后的HARQ信息的映射方式，根据网 络设备的指示信息指示的资源对HARQ调制符号进行资源映射，使得多个终端设备使用同一时频资源进行信息传输时，能够映射到不同的资源上去。因此，本发明实施例能够在多个终端设备使用同一时频资源的系统中传输HARQ信息，提高传输信息的可靠性。
在S410的实现过程中，HARQ信息在调制之前可以进行编码处理。
具体地，作为上述同一时频资源，例如，在以资源单元(RE，Resource Element)为单位的时频资源划分方式下，上述时频资源可以是由多个RE组成的时频资源块(也可以称为时频资源组)，并且，该多个RE可以是在时域上的位置相同(即，对应相同的符号)且在频域上的位置相异(即，对应不同子的载波)，或者，该多个RE可以是在时域上的位置相异(即，对应不同的符号)且在频域上的位置相同(即，对应相同的子载波)，本发明并未特别限定。
可选地，该调制过程可以为通过星座集进行的调制。
应理解，本发明实施例中的终端设备可以为需要发送HARQ信息的终端设备。该终端设备可以为多个需要发送HARQ信息的终端设备中的任一个，为方便描述，本发明实施例仅对一个终端设备进行描述，其他需要发送HARQ信息的终端设备也可以进行相应操作。
可选地，星座集可以为终端设备从网络设备预先定义的星座集，也可以为网络设备分配给终端设备的星座集，本发明实施例并不限于此。还应理解，在本发明实施例中，不同终端设备可以使用相同的星座集。
可选地，本发明实施例中对HARQ信息进行比特编码的方法可以与LTE系统中的比特编码的方法相同，也可以采用其他比特编码的方法，本发明实施例并不限于此。该比特编码的过程可以基于表1和表2进行一步编码，也可以集成在其他操作中完成，直接得到编码后的HARQ信息。

其中，

为一组编码后的HARQ信息。
应理解，终端设备向网络设备发送HARQ调制符号时，可以将HARQ调制符号进行映射到分配的时频资源上去。本发明实施例中可以进一步划分为两部分。第一步骤，将编码后的HARQ信息进行调制成HARQ调制符号。第二步骤，将HARQ调制符号映射到分配的时频资源上去。
第一步骤，将编码后的HARQ信息根据预设的星座集进行星座调制成至少一个HARQ调制符号。具体地，作为一个实施例。若HARQ信息为1比特，则星座调制后可以为1个HARQ调制符号；若HARQ信息为2比特，则星座调制后可以为3个HARQ调制符号,当然本领域技术人员可以知道调制也可以为其他调制方式,不局限于星座调制。
第二步骤，将该至少一个HARQ调制符号映射到分配的时频资源(即子载波)上。应理解，子载波为分配给终端设备子载波。该子载波可以包括至少一个RE。在第一步骤生成的至少一个HARQ调制符号对应目标子载波的至少一个RE。
应理解，不同的终端设备分配的子载波不相同。即每个终端设备分配固定的映射位置。这样，不同的终端设备的HARQ调制符号互相不重叠，能够在网络设备正确解码。
本发明实施例中的第二步骤可以结合图5进行描述。图5以SCMA最大容许六个终端设备接入为例。DMRS符号两侧的固定标号表示一个终端设备的映射位置。例如，在最后一行对应的子载波中，标号为1的四个RE分配给第一个终端设备，同样的，在倒数第7行对应的子载波中，标号为1的四个RE也分配给第一个终端设备。在倒数第二行对应的子载波中，标号为2的四个RE分配给第二个终端设备，在倒数第8行对应的子载波中，标号为2的四个RE也分配给第二个终端设备。以此类推，标号为3、4、5、6的RE分别对应第三个终端设备、第四个终端设备、第五个终端设备和第六个终端设备。六个终端设备从最后一行一次向上排列，每次映射1个调制符号，直至所有终端设备的HARQ信息映射完毕。
应理解，终端设备可以为至少两个终端设备中的需要发送HARQ信息的终端设备中的任一个终端设备。本发明实施例仅对其中一个终端设备进行描述，对于其他需要发送HARQ信息的终端设备也可以采用本发明实施例。
映射资源信息可以为分配给终端设备的子载波的信息。分配给终端设备的子载波的个数与发送的HARQ信息的比特数相关。可选地，作为另一实施例，本发明实施例对映射资源指示信息如何指示分配给终端设备的映射资源信息的方法不做限定，只需要能够指定哪些资源需要分配给终端设备即可。
还应理解，终端设备进行编码的过程和接收映射资源指示信息的过程的先后顺序，本发明实施例并不做限定。对于映射资源指示信息的表现形式， 本发明实施例并不做限定。
可选地，作为另一实施例，映射资源指示信息可以包括至少两个终端设备的标识和至少两个终端设备中的每个待发送HARQ信息的终端设备的待发送HARQ信息的比特个数，至少两个终端设备包括终端设备，并且至少两个终端设备的数据传输采用相同的时频资源进行传输。
可选地，作为另一实施例，映射资源指示信息可以包括分配给至少两个终端设备的中的每一个终端设备用于发送HARQ信息的子载波的起始位置信息和至少两个终端设备的中的每一个待发送HARQ信息的终端设备的待发送HARQ信息的比特个数，至少两个终端设备包括终端设备，并且至少两个终端设备的数据传输采用相同的时频资源进行传输。
可选地，作为另一实施例，映射资源指示信息可以包括至少两个终端设备的标识和至少两个终端设备的个数信息和至少两个终端设备中的每一个待发送HARQ信息的终端设备的待发送HARQ信号的比特个数，至少两个终端设备包括终端设备，并且至少两个终端设备的数据传输采用相同的时频资源进行传输。
具体地，对于该映射资源指示信息的表现形式，本发明实施例并不做限定。可选地，作为一个实施例，若系统中包括6个终端设备，待发送HARQ信息的终端设备有3个，目标终端设备即为该3个待发送HARQ信息的终端设备中的一个终端设备。指示信息可以表示为101100。指示信息的六个比特位分别对应六个终端设备，即终端设备0、1、2、3、4、5、6。其中比特位为1的终端设备0、终端设备2和终端设备3表示需要发送HARQ信息。指示信息还可以包括每个待发送HARQ信息的终端设备的HARQ信息的比特个数。例如，指示信息可以包括2比特，1比特和1比特。表示终端设备0需要发送的HARQ信息为2比特，终端设备2需要发送的HARQ信息为1比特，终端设备3需要发送的HARQ信息为1比特。
可选地，作为另一实施例，映射资源指示信息可以表示为201100。映射资源指示信息的六个比特位分别对应六个终端设备，即终端设备0、1、2、3、4、5、6。其中比特位为1的终端设备0、终端设备2和终端设备3表示需要发送HARQ信息。指示信息还可以包括每个待发送HARQ信息的终端设备的HARQ信息的比特个数。例如，指示信息可以包括2比特，1比特和1比特。指示信息中的第一位2表示终端设备0需要发送的HARQ信息为2比 特，第三位1表示终端设备2需要发送的HARQ信息为1比特，第四位1表示终端设备3需要发送的HARQ信息为1比特。
根据映射资源指示信息中的至少两个终端设备的标识和至少两个终端设备的个数信息，可以确定分配给终端设备的资源的位置信息。
具体地，根据映射资源指示信息，确定分配给终端设备的资源(子载波)的位置信息的过程在36.212标准中可以如下：

例如，基于Format 1A的修改，指示信息可以为ACK/NACK组信息(group information)，ACK/NACK group information可以包括UE_id(4比特)和UE_NUM(4比特)。
可选地，作为另一实施例，映射资源指示信息可以包括分配给终端设备的子载波的起始位置信息和分配给终端设备的子载波的个数信息。
例如，基于Format 1A的修改，指示信息可以为ACK/NACK资源(resource)，其中，ACK/NACK resource可以包括start re_idx(11比特)和total re_num(11比特)。start re_idx表示分配给目标终端设备的至少一个子载波的起始位置信息，total re_num表示分配给目标终端设备的子载波的个数信息。
可选地，作为另一实施例，该方法还可以包括：终端设备还可以发送数据，该数据在除分配给至少两个终端设备用于发送HARQ信息的资源单元上发送。在实现过程中，终端设备在映射数据过程中，可以避开给至少两个终端设备用于发送HARQ信息的资源单元，或者，直接打孔打掉给至少两个终端设备用于发送HARQ信息的资源单元上的数据。
应理解，本发明实施例中网络设备可以根据调度信息获知当前上行子帧调度频带内需要发送上行HARQ信息的终端设备，并向终端设备发送映射资源指示信息。该映射资源指示信息可以包括该终端设备需要发送的HARQ信息的个数和其他终端设备需要发送的HARQ信息的个数。可选地，作为另一实施例，该映射资源指示信息还可以包括终端设备的身份识别号码(ID，IDentity)。这样，终端设备可以确定在当前子帧进行编码时需要清空的时频资源。
图6是本发明另一实施例的传输信息的方法的示意性流程图。图6的方法可以由网络设备执行，该方法600包括：
S610，网络设备发送映射资源指示信息，映射资源指示信息用于指示分配给终端设备对混合自动请求重传HARQ调制符号进行映射的映射资源信息；
S620，网络设备接收终端设备根据映射资源指示信息进行资源映射的HARQ调制符号。
本发明实施例中，通过改变编码后的HARQ信息的映射方式，根据网络设备的指示信息指示的资源对HARQ调制符号进行资源映射，使得多个终端设备使用同一时频资源进行信息传输时，能够映射到不同的资源上去。因此，本发明实施例能够在多个终端设备使用同一时频资源的系统中传输HARQ信息，提高传输信息的可靠性。
图6所示的方法与图5的方法相对应，为避免重复，此处不再详细描述。
可选地，作为另一实施例，HARQ调制符号被映射到解调参考信号DMRS的调制符号一侧或两侧。

可选地，作为另一实施例，本发明实施例还可以包括：终端设备发送数据，发送的数据在除分配给至少两个终端设备用于发送HARQ信息的资源 单元上发送。
图7是本发明一个实施例的传输信息的过程的示意性流程图。图7的过程可以由终端设备执行。该过程包括：
701，将HARQ信息进行比特编码，得到编码后的HARQ信息。
当在PUSCH信道上传输HARQ信息时，该HARQ信息需要先进行编码。HARQ信息可以包括HARQ-ACK信息和HARQ-NACK信息。
具体地，以HARQ-ACK信息为例，若QACK个HARQ-ACK信息进行比特编码，得到QACK组编码后的HARQ信息

其中，
Figure PCTCN2015074622-appb-000048
为一组编码后的HARQ信息。
如果调制阶数为K，则编码后的HARQ信息的长度为N×K，其中，K为2的整数倍，N为大于零的正整数。
例如，若HARQ-ACK信息包含1比特
Figure PCTCN2015074622-appb-000049
调制阶数K为2，则编码后得到的HARQ-ACK信息可以为2比特

Figure PCTCN2015074622-appb-000056

可选地，作为另一实施例，该比特编码过程中还可以增加编码后的HARQ信息的编码长度。具体地，若HARQ信息为1比特，编码后的HARQ信息可以为

N为正整数。若HARQ信息为2比特，HARQ信息比特可以为
Figure PCTCN2015074622-appb-000058
N为正整数。通过重复的信息比特增加编码长度，增加编码冗余量，拉大HARQ-ACK信息比特之间的距离，能够降低编码带来的误差。
应理解，本发明实施例中N的取值可以根据信道环境的好坏，采用不同的编码长度。若信道环境好，可以采用较少的重复次数；若信道环境差，可 以增加重复的次数，以保证HARQ-ACK信息的传输可靠性。

703，将L个HARQ调制符号映射到分配的L个资源单元上。
具体地，与LTE系统不同的是，L个HARQ调制符号每次映射一个Xk，即每次映射L个HARQ调制符号到对应的L个RE上。应理解，该L个资源单元RE可以是在时域上的位置相同(即，对应相同的符号)且在频域上 的位置相异(即，对应不同子的载波)。该映射的规则可以与LTE系统中的映射规则类似，即从最后L行开始映射，对于DMRS两侧的4个符号，依次映射，每次映射到一个符号的L个RE。若还有HARQ调制符号没有映射完成，则向上依次递加L行映射，进行与最后L行相同的映射处理，直到所有HARQ调制符号完成映射。
704，向网络设备发送L个调制符号。
本发明实施例中，通过根据码本对编码后的HARQ信息的进行调制，使得多个终端设备使用同一时频资源进行HARQ信息传输时，能够在网络设备侧进行正确译码。因此，本发明实施例能够在多个终端设备使用同一时频资源的系统中传输HARQ信息，提高传输信息的可靠性。

具体地，本发明实施例中的步骤703可以结合图5进行描述。图5以SCMA最大容许六个终端设备接入为例。DMRS符号两侧的固定标号表示一个终端设备的映射位置。例如，在最后一行对应的子载波中，标号为1的四个RE分配给第一个终端设备，同样的，在倒数第7行对应的子载波中，标号为1的四个RE也分配给第一个终端设备。在倒数第二行对应的子载波中，标号为2的四个RE分配给第二个终端设备，在倒数第8行对应的子载波中，标号为2的四个RE也分配给第二个终端设备。以此类推，标号为3、4、5、6的RE分别对应第三个终端设备、第四个终端设备、第五个终端设备和第六个终端设备。六个终端设备从最后一行一次向上排列，每次映射1个调制符号，直至所有终端设备的HARQ信息映射完毕。
