具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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作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。
应理解，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(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)等。
还应理解，在本发明实施例中，用户设备(UE，User Equipment)包括但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，本发明并不限定。
本发明实施例提供一种基于非正交方式的数据传输、数据接收检测方法及基站、用户设备。基站在发送数据时，首先将多个数据映射到不多于所述数据数量的物理资源上，且所述多个数据中的每一个数据至少被映射到一个物理资源、每一个数据被映射到的物理资源的数量不完全相同，再发送物理资源上的数据，从而实现通过较少的物理资源，发送较 多的数据，提高了通信系统的数据传输能力。
如图2所示，本发明实施例提供的一种数据传输方法，包括：
步骤S201、将多个数据映射到不多于数据数量的物理资源上，且多个数据中的每一个数据至少被映射到一个物理资源、每一个数据被映射到的物理资源的数量不完全相同；
步骤S202、发送所述物理资源上的数据。
由于发送数据的物理资源的数量小于数据的数量，所以提高了通信系统的数据传输能力。
通过功率控制，可以使得每个物理资源中发送的数据数目大于物理资源的数目，但是，为了避免资源浪费，每个物理资源上被映射的数据不大于所述物理资源的数量。
较佳的，可以通过叠加的方式发送同一物理资源上的数据，即，映射到同一物理资源上的数据叠加后进行发送。其中，该叠加为线性叠加。
较佳的，在进行映射时，可以将多个数据分为多个层，前一层中每个数据被映射到的物理资源的数量大于后一层中每个数据被映射到的物理资源的数量；并进一步的，分到同一层中的不同数据，被映射到的物理资源数量可以相同；其中，较佳的，相同类型的层中归属于不同用户的数据之间重叠最小，以及不同类型的层经过图样最大化处理。
进一步的，可以对具有不同等效扩频比(即不为0元素的个数)的相同类型的层进行图样最大化处理，以及对具有相同等效扩频比的相同类型的层进行干扰最小化处理。
所谓进行图样最大化处理，即是保证每一类型的层的数目最多。
基于上述原则，下面以对于N＝2、N＝3、N＝4为例进行说明，其系统扩频矩阵分别为如以下三个公式所示：
Figure PCTCN2015071217-appb-000001
Figure PCTCN2015071217-appb-000002
Figure PCTCN2015071217-appb-000003
如上所述，在N＝3的例子中，可以有3/2/1不同类型的层，对于有效扩频比(即列不为1的个数)为.3的层，在相同类型的层之间干扰最小化的情况下，可以有3种不同分布的图样，对于有效扩频比为2的层，在相同类型的层之间干扰最小化的情况下，可能有3个不同的图样，对于有效扩频比为1的层，在相同类型的层之间干扰最小化的情况下，仅仅有一种图样。这样，便做到了图样最大化。
其他N＝2,4的应用场景，可以以N＝3为基础进行类推，在此不再赘述。
进一步，多个数据可以是属于一个用户的，也可以是属于至少2个用户的。
多个数据属于至少2个用户时，基站首先将至少2个用户N个数据分为K层；再通过总共M个不相关的物理资源发送所述N个数据，其中，N>M，且：对于同一层中的数据，发送该数据占用的不相关的物理资源的数目相同，且大于发送后一层中每个数据占用的不相关的物理资源的数目。
由于基站将N个用户的数据数据分为K层在M个物理资源中发送，后一层中的数据的发送分集度小于前一层中的数据的发送分集度，基于串行干扰删除接收机的数据流分集度在第一层获得的最低，之后依层递增。而基于本发明实施例提供的发送方式，使得后一层中的数据的发送分集度小于前一层中的数据的发送分集度，第一层数据的发送分集度最大。从而保证了每一层数据在经过串行干扰删除接收机的检测后的分集度相近，以便于用户解出自身对应的数据。
其中，发送分集度是指，发送该数据所占用的不相关的物理资源的数目。两个不相关的物理资源上承载的数据是不相关的；若在同一个物理资源上承载多个数据，则此多个数据是相关的。通常，在同一个物理资源上是通过线性叠加的方式进行多个数据的发送。
通过功率控制，可以使得每个物理资源中发送的数据数目大于M，即K可以大于M，但是，K>M时，容易造成不必要的资源浪费，通常情况下，K小于或等于M时，UE就可以解出自身对应的数据，所以，基站在每个物理资源中发送不大于M个数据较佳。
较佳的，基站可以在一定粒度的物理资源中均发送M个数据，减少资源的浪费，同时，也便于各用户较准确的解出自身对应的数据。
在接收端，利用串行干扰删除接收方式进行信号检测。基于串行干扰删除接收机第i 层数据流的接收分集度为：
N分集度＝NR-NT+i.
其中，NR为数据的发送分集度和接收天线数之和，NT为数据的发送天线数。
因为串行干扰删除在做检测时，第一层的通过串行干扰删除检测出来的数据由于检测带来的分集度最低，后一层检测的数据分集度为前一层检测的数据分集度加1。由此可见基串行干扰删除接收机系统性能取决于第一层干扰删除的准确度。基于此，本发明实施例提供一种非正交联合设计发送方式，其发送的基本原则是使得前一层中的数据的发送分集度大于后一层中的数据的发送分集度。从而保证了每一层数据在通过串行干扰删除后的分集度相近。
数据流可以考虑在频率，空间或者时间等等的其中一维维度上实现物理资源的不相关，也可以在任何其中的任二维维度实现物理资源的不相关，以此类推。
以三个用户、两个不相关的物理资源为例，如图3a所示，按照如下方式发送：
Figure PCTCN2015071217-appb-000004
其中，用户1第一个发送的s1与第二个发送的s1在时间，或者频率，或者空间是不相关的，这样保证其在接收端可以获得2重分集度。对于1*2的SIMO(单输入多输出)系统由于用户1，s1符号分集度是2，可靠度最高，最先解调，这时基于串行干扰删除接收机的检测后信号s1的分集度为
4＝2(2个符号)+2(2根接收天线)-1+1；
在解调完第一个符号s1后，用户2、用户3的数据s2和s3和检测后分集度为：
4＝1(1个符号)+2(2根接收天线)-1+2；
对于一个多数据流系统，每个数据流的接收分集度相同时，对应的发送方式是较可靠的，同理可以推广到大于2个数据流的情况。
以LTE系统为例，若需要实现上述发送，可以按照如图3b的方式进行发送，图3b中，纵向表示频域，横向表示时间，用户1、2的数据在第一频域区域发送，用户1、3的数据在第二频域区域发送。
如图3c所示，两个正交物理资源也可以用于发送两个数据，此时，用户2可以分别在两个正交物理资源中发送两份数据：S2和S2’。
对于五个用户、三个正交物理资源的情况，一种较佳的发送方式如图4所示，按照如下方式发送：
Figure PCTCN2015071217-appb-000005
即，第一个物理资源中发送第一、二、五个数据，第二个物理资源中发送第一、二、三个数据，第三个物理资源中发送第一、三、四个数据，各用户数据的发送分集度关系为：用户1>用户2＝用户3>用户4＝用户5，假设发射天线数和接收天线数均为3根，则各用户的接收分集度为：
Figure PCTCN2015071217-appb-000006
Figure PCTCN2015071217-appb-000007
Figure PCTCN2015071217-appb-000008
图4所示的发送方式也可以通过矩阵表示为：
Figure PCTCN2015071217-appb-000009
对于通过总共M个不相关的物理资源发送N个数据来说，基站可以通过如下方式进行发送：
Figure PCTCN2015071217-appb-000010
其中，s1～sN分别为N个数据，
Figure PCTCN2015071217-appb-000011
为N*M维的非正交发送方式的生成矩阵，矩阵G中属于同一层数据对应的各个行中1的个数相同，矩阵G的每行中1 的个数分别记为n1,n2,n3,…,nN，并且n1≥n2≥n3≥…≥nN。
较佳的，可以按照如下方式进行分层和发送：
Figure PCTCN2015071217-appb-000012
其中，行重是指，该行中1的个数，该行重等于发送相应数据所占用的物理资源个数，此时，n1>n2＝n3≥…≥nN。
或者，当K＝M时，也可以表示为如下M维方阵：
Figure PCTCN2015071217-appb-000013
此时，第一个物理资源中，可以发送第一行数据的和：s1+s2+s4+……+sN；
第二个物理资源中，可以发送第二行数据的和：s3+s1+s2+……+sN-2；
……

……
第M个物理资源中，可以发送第M列数据的和：sN+……+s4+s2+s1。
本发明实施例还相应提供一种数据接收检测方法，如图5所示，包括：
步骤S501、UE在多个物理资源上接收基站发送的数据；
步骤S502、UE根据数据在多个物理资源上的映射方式进行解调检测，其中，多个物理资源上映射了不少于物理资源数量的多个数据，且多个数据中的每一个数据至少被映射到一个物理资源、每一个数据被映射到的物理资源的数量不完全相同。
通过功率控制，可以使得每个物理资源中发送的数据数目大于物理资源的数目，但是， 为了避免资源浪费，每个物理资源上被映射的数据不大于所述物理资源的数量。
较佳的，可以通过叠加的方式发送同一物理资源上的数据，即，映射到同一物理资源上的数据叠加后进行发送。其中，该叠加为线性叠加。
较佳的，在进行映射时，可以将多个数据分为多个层，前一层中每个数据被映射到的物理资源的数量大于后一层中每个数据被映射到的物理资源的数量；并进一步的，分到同一层中的不同数据，被映射到的物理资源数量可以相同；其中，较佳的，相同类型的层中归属于不同用户的数据之间重叠最小，以及不同类型的层经过图样最大化处理。
进一步的，可以对具有不同等效扩频比(即不为0元素的个数)的相同类型的层进行图样最大化处理，以及对具有相同等效扩频比的相同类型的层进行干扰最小化处理。
进一步，多个数据可以是属于一个用户的，也可以是属于至少2个用户的，UE在解调检测后得到属于自己的数据。
较佳的，UE采用串行干扰消除方式进行解调检测。串行干扰消除技术一般是依次解调检测出各层数据，前一层的解调检测结果用于后一层进行干扰消除，利用消除了前一层数据干扰影响的结果进行后一层的数据检测。
进一步，UE优先检测每个数据被映射到的物理资源数量较多的层的数据。
本发明实施例中的一种较具体的数据接收检测方法，如图6所示，包括：
步骤S601、UE接收基站通过不多于数据数量的物理资源发送的多个数据，所述多个数据中的每一个数据至少被映射到一个物理资源、每一个数据被映射到的物理资源的数量不完全相同；
步骤S602、UE通过串行干扰删除接收方式，从第一层开始，依次解出各层数据，直至解出自身对应的数据。
较佳的，步骤S601中，具体包括：UE接收基站通过M个正交物理资源，向至少2个用户发送的N个数据，其中，M<N，且满足：
该N个数据分为K层，通过总共M个不相关的物理资源发送，且：对于同一层中的数据，发送该数据占用的不相关的物理资源的数目相同，发送前一层中每个数据占用的不相关的物理资源的数目都大于发送后一层中每个数据占用的不相关的物理资源的数目。
从第一层开始依次解出各层数据时，各用户的平均计算复杂度较小。
仍以如图3a所示的三个用户、两个正交物理资源为例，对于用户1来讲，用户1接收信号为：
y11＝h11(s1+s2)+n11
y12＝h12(s1+s3)+n12
其中，h11为前一半符号经历的信道矩阵，h12为后一半符号经历的信道矩阵。
用户1检测时，s2和s3被当成干扰信号，首先，用户1对接收信号进行归一化处理。
然后，用户1使用MMSE(minimum mean square error，最小平方差)检测得到s1+s2、s1+s3，再确定符号s1的对数使然比LLR1(s1)和LLR2(s1)，最后，利用LLR1(s1)+LLR2(s1)进行软解调，得到

对于用户2：
用户2接收信号为：
y21＝h21(s1+s2)+n21
y22＝h22(s1+s3)+n22
用户2获得自身对应的数据的思路是，先检测符号s1，得
