Description

数据处理的方法、装置和设备 技术领域
本发明涉及通信领域，并且更具体地，涉及数据处理的方法、装置和设备。
背景技术
随着技术的发展进步，在例如，稀疏码分多址(SCMA，Sparse Code Multiple Access)技术或正交频分复用(OFDM，Orthogonal Frequency Division Multiplexing)等技术中，已经能够允许多个终端设备复用相同的时频资源进行数据传输，即，发送端设备可以在对需要传输的多层信息比特进行编码调制以生成多层调制符号，并在时频资源上对该多层调制符号进行叠加处理之后，通过空口发送给接收端设备。
目前，已知一种多输入多输出(MIMO，Multi-Input Multi-Output)技术，即，发送端设备和接收端设备可以通过多个天线端口进行数据传输，以提高提高系统容量和传输可靠性。
因此，希望将多输入多输出技术与稀疏码分多址或正交频分复用等复用技术相结合，从而进一步提高通信系统性能。
如何将上述多输入多输出技术和稀疏码分多址等技术结合，以更大限度的提高系统容量和传输可靠性，是急需解决的问题。
一种可行的方案是发送端设备可以在完成在时频资源上对多层调制符号的叠加处理之后，对所生成的已承载于时频资源上的信号进行预编码处理，以生成各天线端口所对应的发射信号。
但是，在这种方案中，无法有效利用空间分集增益，例如，在同一时频资源上承载有多个终端设备的信号情况下，经上述预编码处理后，多个用户的信号分量通过同一个端口发送，无法同时选择各自最优的天线端口，各分量之间的相互干扰造成接收端译码时的误码率较高，严重影响了通信的可靠性。

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。

此外，本发明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，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、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是使用本发明的数据处理的方法的通信系统的示意图。如图1所示，该通信系统100包括网络侧设备102，网络侧设备102可包括多个天线组。每个天线组可以包括多个天线，例如，一个天线组可包括天线104和106，另一个天线组可包括天线108和110，附加组可包括天线112和114。图1中对于每个天线组示出了2个天线，然而可对于每个组使用更多或更少的天线。网络侧设备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)。
网络侧设备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，网络侧设备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(FDD，Frequency Division Duplex)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(TDD，Time Division Duplex)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。
图2示出了从发送端设备描述的根据本发明一实施例的传输信息的方法 200的示意性流程图。如图2所示，该方法200包括：
S210，发送端设备对L层信息比特进行映射处理，以生成L层调制符号序列，每层调制符号序列包括U个调制符号，L层调制符号序列对应同一时频资源，该U个调制符号包括至少一个非零调制符号和至少一个零调制符号，L≥2，U≥2；
S220，根据L个预编码矩阵中每层调制符号序列所对应的预编码矩阵，对每层调制符号序列进行预编码处理，以生成L层调制符号序列矩阵，其中，该L个预编码矩阵与该L层调制符号序列一一对应，该预编码矩阵在第一维度上包括T个元素序列，T为用于传输该L层信息比特的空域资源的数量，T≥2；
S230，对该L层调制符号序列矩阵进行叠加处理，以生成待发送符号序列矩阵，其中，该待发送符号序列矩阵在该第一维度上包括T个元素序列，该待发送符号序列矩阵在第二维度上包括U个元素序列。
可选地，该发送端设备为网络设备，或
该发送端设备为终端设备。
在本发明实施例中，发送端设备可以是网络设备(例如，网络侧设备)，即，该方法200可以应用于下行传输。
或者，发送端设备可也可以是终端设备(例如，用户设备)，即，该方法200可以应用于上行传输。
以下，为了便于理解和说明，以网络设备作为发送端设备(即，本发明是实施例的数据处理的方法200的执行主体)为例，对上述方法200的流程进行详细说明。
具体的，在S210，网络设备可以对需要发送给L个终端设备(以下，为了便于理解和说明，记做终端设备#1～终端设备#L)的信息比特，进行映射处理，以生成L个符号序列，需要说明的是，在使用本发明实施例的数据处理的方法200的通信系统100中，多个终端设备复用同一时频资源与网络设备进行数据传输，即，上述L个符号序列对应同一视频资源。
并且，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，该映射处理为通过码字进行的映射处理，该码字为多维复数向量，用于表示信息比特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。
并且，可选地，该发送端设备对L层信息比特进行映射处理，包括：
发送端设备以稀疏码分多址SCMA方式，对L层信息比特进行映射处理。
具体地说，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。
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。
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。
SCMA采用的码字可以具有一定稀疏性，比如说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，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，每个数据流的数据分别表示为s1至s6，每个资源单元发送的符号分别表示为x1至x4，并且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符号(与零元素相对应)，也可以为非零符号(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扩展后会在多个资源单元上发送，同时，每个资源单元发送的符号是来自多个数据流的数据经扩展后的非零符号的叠加。例如数据流3的数据s3经扩展后会在资源单元1和资源单元2上发送非零符号，而资源单元3发送的数据x2是数据流2、数据流4和数据流6的数据s2、s4和s6分别经扩展后得到的非零符号的叠加。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。
码本中的码字通常具有如下形式：
Figure PCTCN2014093534-appb-000001
而且，相对应的码本通常具有如下形式：
Figure PCTCN2014093534-appb-000002
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，与调制阶数对应，例如，在采样四相相移键控(QPSK，Quadrature Phase Shift Keying)或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可以为任意实数，β可以为任意值，N和Qm可以为正整数。
并且，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2比特数据形成一种映射关系。
例如，“00”可以对应码字1，即
Figure PCTCN2014093534-appb-000003
“01”可以对应码字2，即
Figure PCTCN2014093534-appb-000004
“10”可以对应码字3，即
Figure PCTCN2014093534-appb-000005
“11”可以对应码字4，即
Figure PCTCN2014093534-appb-000006
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。
综上所述，当调制阶数为QPSK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 PCTCN2014093534-appb-000007
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

且

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 PCTCN2014093534-appb-000010
应理解，以上列举的SCMA系统仅为适用本发明的数据处理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数据传输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，上述映射处理的过程可以和现有的SCMA系统中的映射处理过程类似，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S210的映射处理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。
在S220，网络设备可以确定各符号分别对应的预编码矩阵。
其中，预编码矩阵也可以称为预编码码字，用于指示控制比特与预编码向量之间的映射关系。
首先，对预编码矩阵中各维度包括的元素的数量进行说明。
在本发明实施例中，矩阵的维度包括行和列，即，上述第一维度可以是矩阵的行方向，上述第二维度可以是矩阵的列方向；或者，上述第一维度可以是矩阵的列方向，上述第二维度可以是矩阵的行方向，本发明并未特别限定。
在本发明实施例中，各预编码矩阵中的一个维度(即，第一维度的一例)所包括的元素的数量相同，均为T，以下为了便于理解，以行方向作为该第一维度为例，进行说明，即，各预编码矩阵包括T行。其中，T为该网络设备发送该L个调制符号序列所使用的空域资源的数量。
可选地，T具体为用于传输该L层信息比特的天线端口的数量。
具体地说，T可以为该网络设备发送该L个调制符号序列时所使用的天线端口的数量，或者说，T可以为该网络设备该L个调制符号序列时所使用的天线的数量。
对于另一维度(即，第二维度的一例，以下为了便于理解，以列方向作为该第二维度为例，进行说明)。该维度所包括的元素的数量可以相同(即，情况1)，也可以相异(即，情况2)，本发明并未特别限定。下面，分别对以上两种情况进行详细说明。
情况1
可选地，每个预编码矩阵在该第二维度上包括U个元素序列，每个预编码矩阵所包括的非零元素序列在该U个序列中的位置与所对应的调制符号序列所包括的非零调制符号在该U个调制符号中的位置相对应。
具体的，在本发明实施例中，可以使各预编码矩阵的规模相同，即，各预编码矩阵中每行包括的元素的数量相同，每列包括的元素的数量相同。
如上所述，在本发明实施例中，各预编码矩阵包括T行，即，各预编码矩阵中的每列包括T个元素。
并且，在本发明实施例中，各预编码矩阵包括U列(即，U个元素序列)，即，各预编码矩阵中的每行包括U个元素。
不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#7，以调制符号序列#7所对应的预编码矩阵#7为例，该预编码矩阵#7所包括U列元素(即，U个元素序列)中，包括V个非零列(即，非零元素序列)。并且，该V个非零列的每一列中，至少包括一个非零元素。其中，V个非零列在该预编码矩阵#7中的位置(例如，序号)，与非零调制符号在该调制符号序列#7位置(例如，序号)相同。
应理解，以上列举的位置相同的方式仅为位置相对应的示例性说明，本发明并不限定于此，例如，可以根据生成该非零列在该预编码矩阵中的位置与非零调制符号在调制符号序列中的位置的关系式，并根据该关系式，确定各调制符号序列所对应的预编码矩阵。
随后，对预编码处理和该情况1所对应的叠加处理的过程进行说明。
情况2
可选地，该L层调制符号序列中的第六调制符号序列包括V个非零调制符号，V≥1，以及
在与该第六调制符号序列相对应的第六预编码矩阵中，该第六预编码矩阵在第二维度方向上包括V个元素序列；
该根据每层调制符号序列所对应的预编码矩阵，对每层调制符号序列进行预编码处理，包括：
根据该第一预编码矩阵，对第一调制符号序列进行预编码处理，以生成第一调制符号序列矩阵，该第一调制符号序列矩阵在该第一维度上包括T个元素序列，该第一调制符号序列矩阵在该第二维度上包括V个元素序列。
具体的，在本发明实施例中，可以使各预编码矩阵的规模相同，即，各预编码矩阵中每行包括的元素的数量相同，每列包括的元素的数量相同。
如上所述，在本发明实施例中，各预编码矩阵包括T行，即，各预编码矩阵中的每列包括T个元素。
并且，在本发明实施例中，各预编码矩阵包括的列数可以相异。
不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#6，以调制符号序列#6(即，第六调制符号序列的一例)所对应的预编码矩阵#6(即，第六预编码矩阵的一例)为例，该预编码矩阵#6所包括的列数与调制符号序列#6所包括的非零元素的数量相同，即，该预编码矩阵#6包括V列元素(即，V个元素序列)。
应理解，在本发明实施例中，第六调制符号序列可以是L层调制符号序列中的一层调制符号序列，也可以是L层调制符号序列中的多层调制符号序列，本发明并未特别限定，并且，当第六调制符号序列是L层调制符号序列中的多层调制符号序列时，针对其中的每层调制符号序列的处理与上述调制符号序列#6的处理类似。为了避免赘述，省略对于相同或相似情况的说明。
随后，对预编码处理和该情况2所对应的叠加处理的过程进行说明。
以上，对根据本发明实施例的方法200所确定的预编码矩阵的规模(即，行数和列数)进行了说明。
下面，对预编码矩阵中非零列(即，至少包括一个非零元素的列)中的元素的确定方法进行说明。
可选地，当该L层调制符号序列中的第一调制符号序列包括至少两个非零调制符号时，在与该第一调制符号相对应的第一预编码矩阵中，该第一预编码矩阵在该第二维度上包括至少两个第一元素序列，该至少两个第一元素序列与该第一调制符号序列包括的至少两个非零调制符号一一对应，该至少两个第一元素序列相异。
具体地说，如果一个调制符号序列包括两个或两个以上非零元素，则可以使该调制符号序列所对应的预编码矩阵中的与该两个或两个以上非零元素对应的两个或两个以上的列彼此相异。
例如，不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#1，以调制符号序列#1(即，第一调制符号序列的一例)所对应的预编码矩阵#1(即，第一预编码矩阵的一例)为例。
在该调制符号序列#1包括两个或两个以上非零调制符号时，该预编码矩阵#1所包括的非零列(即，第一元素序列的一例)的数量与调制符号序列#1所包括的非零元素的数量相同，并且，各非零列彼此相异，这里，使各非零列彼此相异可以通过以下方式实现：
对N个非零列进行配对，以生成
Figure PCTCN2014093534-appb-000011
个非零列对，其中，每两个非零列对中的至少一个非零列彼此相异。
并且，对于任意一个非零列对所包括的两个非零列中，至少一个相同位置(即，在列中的序号相同的位置)上的元素彼此相异。
根据本发明实施例的数据处理的方法，同一调制符号序列中的非零元素需要发送至同一接收端设备，因此，通过使同一调制符号序列中的非零元素所对应的预编码矩阵中的元素序列相异，能够使各非零元素对应于不同的子信道，从而能够降低各非零元素之间的干扰，进一步降低接收端译码时的误码率，提高通信的可靠性。
可选地，该预编码矩阵是根据每层调制符号序列所对应的接收端设备确定的。
在本发明实施例中，对于任意两个调制符号序列，其对应的接收端设备可能相同(即，情况A)，也可能相异(即，情况B)，下面分别对以上两种情况下的处理，进行详细说明。
情况A
可选地，当该L层调制符号序列中的第二调制符号序列所对应的接收端设备与该L层调制符号序列中的第三调制符号序列所对应的接收端设备相同时，
在与该第二调制符号序列相对应的第二预编码矩阵中，该第二预编码矩阵在该第二维度上包括第二元素序列，该第二元素序列与第二非零调制符号相对应，该第二非零调制符号属于该第二调制符号序列包括的非零调制符号，
在与该第三调制符号序列相对应的第三预编码矩阵中，该第三预编码矩阵在该第二维度上包括第三元素序列，该第三元素序列与第三非零调制符号相对应，该第三非零调制符号属于该第三调制符号序列包括的非零调制符号，
其中，该第二非零调制符号在该第二调制符号序列中的位置与该第三非 零调制符号在该第三调制符号序列中的位置相对应，该第二元素序列与该第三元素序列相同。
具体地说，如果两个调制符号序列所对应的接收端设备相同，则可以使这两个调制符号序列所对应的预编码矩阵中的彼此对应的两列元素相同。
例如，不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#2，以调制符号序列#2(即，第二调制符号序列的一例)所对应的预编码矩阵#2(即，第二预编码矩阵的一例)为例。并且，将上述L层调制符号序列中的另一个调制符号序列记做：调制符号序列#3，以调制符号序列#3(即，第三调制符号序列的一例)所对应的预编码矩阵#3(即，第三预编码矩阵的一例)为例。
设该调制符号序列#2包括A个非零调制符号，则如上所述，该预编码矩阵#2所包括的非零列(即，第二元素序列的一例)的数量与调制符号序列#2所包括的非零元素的数量相同，并且，各非零列彼此相异，将预编码矩阵#2所包括的非零列记做非零列#21～非零列#2A。
设该调制符号序列#3包括B个非零调制符号，则如上所述，该预编码矩阵#3所包括的非零列(即，第三元素序列的一例)的数量与调制符号序列#3所包括的非零元素的数量相同，并且，各非零列彼此相异，将预编码矩阵#3所包括的非零列记做非零列#31～非零列#3B。
当A≤B时，可以使非零列#21与非零列#31相同，使非零列#22与非零列#32相同，依次类推，直至使非零列#2A与非零列#3A相同。
这里，需要说明的是，两个列(即，两个元素序列)相同可以是指两列中各位置上的元素均相同。
根据本发明实施例的数据处理的方法，当两个调制符号序列需要发送至同一接收端设备时，通过使两个调制符号序列中位置相对应(例如，相同)的非零元素所对应的预编码矩阵中的元素序列相同，能够实现通过相同的信道向同一接收端设备发送数据，能够进一步提高通信的可靠性。
情况B
可选地，当该L层调制符号序列中的第四调制符号序列所对应的接收端设备与该L层调制符号序列中的第五调制符号序列所对应的接收端设备相异时，
在与该第四调制符号序列相对应的第四预编码矩阵中，该第四预编码矩 阵在该第二维度上包括第四元素序列，该第四元素序列与第四非零调制符号相对应，该第四非零调制符号属于该第四调制符号序列包括的非零调制符号，
在与该第五调制符号序列相对应的第五预编码矩阵中，该第五预编码矩阵在该第二维度上包括第五元素序列，该第五元素序列与第五非零调制符号相对应，该第五非零调制符号属于该第五调制符号序列包括的非零调制符号，
其中，该第四非零调制符号在该第四调制符号序列中的位置与该第五非零调制符号在该第五调制符号序列中的位置相对应，该第四元素序列与该第五元素序列相异。
具体地说，如果两个调制符号序列所对应的接收端设备相异，则可以使这两个调制符号序列所对应的预编码矩阵中的彼此对应的两列元素相异。
例如，不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#4，以调制符号序列#4(即，第四调制符号序列的一例)所对应的预编码矩阵#4(即，第四预编码矩阵的一例)为例。并且，将上述L层调制符号序列中的另一个调制符号序列记做：调制符号序列#5，以调制符号序列#5(即，第五调制符号序列的一例)所对应的预编码矩阵#5(即，第五预编码矩阵的一例)为例。
设该调制符号序列#4包括C个非零调制符号，则如上所述，该预编码矩阵#4所包括的非零列(即，第四元素序列的一例)的数量与调制符号序列#4所包括的非零元素的数量相同，并且，各非零列彼此相异，将预编码矩阵#4所包括的非零列记做非零列#41～非零列#4C。
设该调制符号序列#5包括D个非零调制符号，则如上所述，该预编码矩阵#5所包括的非零列(即，第五元素序列的一例)的数量与调制符号序列#5所包括的非零元素的数量相同，并且，各非零列彼此相异，将预编码矩阵#5所包括的非零列记做非零列#51～非零列#5D。
当C≤D时，可以使非零列#41与非零列#51相异，使非零列#42与非零列#52相异，依次类推，直至使非零列#4C与非零列#5C相异。
这里，需要说明的是，两个列(即，两个元素序列)相异可以是指两列中至少一个位置上的元素相异。
根据本发明实施例的数据处理的方法，当两个调制符号序列需要发送至 不同接收端设备时，通过使两个调制符号序列中位置相对应(例如，相同)的非零元素所对应的预编码矩阵中的元素序列相异，能够实现通过相异的信道向不同接收端设备发送数据，从而能够降低不同接收端设备的数据之间的干扰，进一步降低接收端译码时的误码率，进一步提高通信的可靠性。
在如上所述确定各调制符号序列所对应的预编码矩阵后，网络设备可以对各调制符号序列进行预编码处理。
具体地说，设在经过例如SCMA编码后，将L层信息比特分别映射为调制符号序列xl l＝1,…,L。
以对xl的预编码处理为例，以xl中的非零符号为对角元素，构成对角矩阵
Figure PCTCN2014093534-appb-000012
从而，可以根据以下式1对xl进行预编码，得到xl所对应的调制符号序列矩阵yl
Figure PCTCN2014093534-appb-000013
其中，Wl为T行V列的矩阵，在符合上述情况A或情况B所描述的方案的情况下，该矩阵中的各元素的确定方法可以与现有技术相似，这里为避免赘述，省略其详细说明。
在S230，网络设备可以对如上所述生成的各调制符号序列矩阵进行叠加处理。
在本发明实施例中，网络设备可以根据每层调制符号序列中非零调制符号的位置，进行上述叠加处理。
例如，网络设备可以将各调制符号序列矩阵中对应相同RE的列相叠加，得到各RE所对应的待发送符号序列。
例如，可选地，该确定L个预编码矩阵，包括：
确定L个预编码矩阵，其中，每个预编码矩阵在该第二维度上包括U个元素序列，每个预编码矩阵所包括的非零元素序列在该U个序列中的位置与所对应的调制符号序列所包括的非零调制符号在该U个调制符号中的位置相对应；以及
对该L层调制符号序列矩阵进行叠加处理，包括：
对该L层调制符号序列矩阵中在该第一维度上的位置相对应且在该第二维度上的位置相对应的元素进行叠加处理。
具体地说，在情况1下，由于所确定的各预编码矩阵的规格相同，即，行数列数均相同，因此，经过预编码处理而得到的L个调制符号序列矩阵的规格也相同，即，行数列数均相同，此情况下，可以将L个调制符号序列矩阵中，位置(即，行位置相同，列位置也相同)相同的各元素相叠加，以生成待发送符号序列矩阵。
再例如，可选地，在该对该L层调制符号序列矩阵进行叠加处理之前，该方法还包括：
根据该V个非零调制符号在该第六调制符号序列中的位置，对该第六调制符号序列矩阵进行补零处理，以使经过该补零处理后的第六调制符号序列矩阵在该第二维度上包括U个元素序列，其中，经过该补零处理后的第一调制符号序列矩阵中的V个非零元素序列在该第二维度上的位置与该V个非零调制符号在该第六调制符号序列中的位置相对应。
具体地说，在情况2下，由于所确定的各预编码矩阵的规格相异，即，行数或列数相异，因此，经过预编码处理而得到的L个调制符号序列矩阵的规格也相异，即，行数列数均相异。
不失一般性，将上述L层调制符号序列中的一个调制符号序列记做：调制符号序列#6，以调制符号序列#6(即，第六调制符号序列的一例)所对应的预编码矩阵#6(即，第六预编码矩阵的一例)为例，该预编码矩阵#6所包括的列数与调制符号序列#6所包括的非零元素的数量相同，即，该预编码矩阵#6包括V列元素(即，V个元素序列)，根据上述式1所生成的调制符号序列矩阵#6为T行V列(即，V个非零元素序列)，此情况下，该V列与调制符号序列#6中的V个非零元素相对应，可以使V个非零元素序列在预编码矩阵#6中的位置与V个非零元素在调制符号序列#6中的位置相对应，其他位置补零序列，从而，能够将调制符号序列矩阵#6转化为T行U列的矩阵。类似的，各调制符号序列矩阵均可以转化为T行U列的矩阵，从而，可以将转化后的L个调制符号序列矩阵中，位置(即，行位置相同，列位置也相同)相同的各元素相叠加，以生成待发送符号序列矩阵。
图4示出了在将本发明实施例的方法200应用于SCMA系统时的流程示意图，如图4所示，在经过上述S210中描述的方法对终端设备#1～终端设备#L所对应的信息比特(即，信息比特#1～信息比特#L)进行映射处理后，可以生成分别与终端设备#1～终端设备#L相对应的调制符号序列X#1～X#L， 并且各调制符号序列稀疏地映射在由RE#1～RE#4构成的资源块上，在经过上述S230中描述的预编码处理(基于上述S220生成的L个预编码矩阵实现)后，生成各终端设备所对应的调制符号序列矩阵，并且，该调制符号序列矩阵可以对应该空域资源(即，天线端口#1～天线端口#4)和时频资源(即，RE#1～RE#4)构成的二维资源矩阵，在经过上述S240描述的叠加处理后，生成待发送符号序列矩阵。
需要说明的是，在上述终端设备#1～终端设备#L中，对于任意两个终端设备，可以是同一终端设备也可以是不同的终端设备，本发明并未特别限定，例如，当终端设备#1与终端设备#L为同一终端设备时，表示信息比特#1与信息比特#L需要发送至同一终端设备，当终端设备#1与终端设备#L为不同终端设备时，表示信息比特#1与信息比特#L需要发送至不同的终端设备。
并且，上述空域资源的数量和时频资源的数量仅为示例性说明，本发明并未限定于此。
另外在本发明实施例中，由于预编码矩阵是根据所对应的调制符号序列(例如，调制符号序列的接收端设备和所包含的非零符号数量)确定的，因此，L个预编码矩阵中的任意两个预编码矩阵可以是相同的，也可以是相异的，本发明并未特别限定。
根据本发明实施例的数据处理的方法，发送端设备可以获取多层调制符号所分别对应的多个预编码矩阵，并基于该多个预编码矩阵分别对所对应的调制符号分别进行预编码处理，以获取每层调制符号的针对各空域资源的分量，并对上述经过预编码处理后的多层调制符号进行叠加处理，能够有效利用空间分集增益，提高所生成的各空域资源所对应的待发射信号的信噪比，降低接收端译码时的误码率，能够显著提高通信的可靠性。
