本申请主张在2014年11月14日在中国提交的中国专利申请号No.201410649623.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，特别涉及一种进行数据传输的方法和设备。
背景技术
从第一代移动通信技术到目前的第四代移动通信技术，传统移动通信多址技术主要是利用正交多址接入技术，如FDMA(Frequency Division Multiple Access，频分多址)，TDMA(Time Division Multiple Access，时分多址)，CDMA(Code Division Multiple Access，码分多址)，OFDMA(Orthogonal Frequency Division Multiple Access，正交频分多址)，SDMA(Space Division Multiple Access，空分多址)等来实现无线资源的共享。4G中采用基于正交和同步频分复用技术，各个用户所占用的时频资源块是不同的。
从多用户信息理论的角度来看，正交方式只能达到多用户容量界的内界，根据多用户信息论的原理，在广播信道下，两个用户的可达速率是一个凸五边形，最边沿的速率可以通过发送端进行叠加编码(非正交编码)，也就是说基站将发送给两个用户的信号进行线性叠加，利用相同的物理资源发送出去；并且在接收端采用干扰删除接收机，可以达到比正交方式更高的多用户系统容量。从提升频谱效率的角度而言，非正交接入技术有着潜在的优势。
图样分割非正交多址接入技术，简称PDMA(Pattern Division Multiple Access，图分多址)技术，是基于多用户通信系统整体优化、通过发送端和接收端联合处理的技术，在发送端，基于多个信号域的非正交特征图样来区分用户，在接收端，基于用户图样的特征结构，采用串行干扰抵消方式来实现多用户检测，从而做到多用户在已有时频无线资源的进一步复用。

具体实施方式
本公开实施例发送设备根据由多用户复用的编码矩阵确定的逻辑资源单元组，将调度后每个用户的数据符号进行分组；根据所述编码矩阵对用户的每组数据符号进行编码，确定每组数据的编码符号；根据所述逻辑资源单元，将各用户的每组数据符号进行映射处理；根据映射方式，将每个逻辑资源单元组向物理资源块进行映射；根据映射后的所述物理资源块向接收设备发送数据。由于根据由多用户复用的编码矩阵确定的逻辑资源单元组，以及根据映射方式，将每个逻辑资源单元组向物理资源块进行映射，并且根据映射后的所述物理资源块向接收设备发送数据，从而实现针对非正交接入方式下进行资源映射，提高了资源利用率。
下面结合说明书附图对本公开实施例作进一步详细描述。
如图1A所示，根据本公开实施例一进行数据传输的系统包括：发送设备10和接收设备20。
发送设备10，用于根据由多用户复用的编码矩阵确定的逻辑资源单元组，将调度后每个用户的数据符号进行分组；根据所述编码矩阵对用户的每组数据符号进行编码，确定每组数据的编码符号；根据所述逻辑资源单元，将各用户的每组数据符号进行映射处理；根据映射方式，将每个逻辑资源单元组向物理资源块进行映射；根据映射后的所述物理资源块向接收设备发送数据。
接收设备20，用于根据映射方式，对承载用户的数据的物理资源块进行反映射，确定逻辑资源单元组；对所述逻辑资源单元组进行反映射处理，确定用户的数据；根据多用户复用的编码矩阵对用户的数据进行解码，确定至少一个用户的数据符号。
这里确定逻辑资源单元组实际是确定组成逻辑资源单元组的资源的具体位置。
在实施中，调度后的每个用户的数据符号可以是MAC(Medium Access Control；媒体接入控制)调度后的每个用户的数据符号。
其中，如果是上行传输，则发送设备是用户设备，接收设备是网络侧设备；如果是下行传输，则发送设备是网络侧设备，接收设备是用户设备。
本公开实施例的网络侧设备可以是基站(比如宏基站、家庭基站等)，也可以是RN(中继)设备，还可以是其它网络侧设备。
下面分别进行介绍。
一、下行传输：
在实施中，发送设备根据多用户上报的信道情况，或者通过上行导频和互异性获得的信道情况，选择多用户复用的编码矩阵，并将编码矩阵通知给接收设备。
例如如果使用N＝3个资源单元，复用7个用户，则可以采用下面的编码矩阵：
Figure PCTCN2015089546-appb-000001
资源单元组可根据信道情况、编码复杂度、开销等进行调整并做规定，例如如果资源单元组为4，用户数为8，则可以采用下面的编码矩阵：
Figure PCTCN2015089546-appb-000002
需要说明的是，上述编码矩阵只是举例说明，本公开实施例的编码矩阵并不局限与上述的例子，其他编码矩阵也同样适用本公开实施例。并且同样是N＝3个资源单元，复用7个用户的情况也可以采用与上述N＝3个资源单元、复用7个用户的例子的编码矩阵不同。同理N＝4个资源单元、复用8个用户的例子的也可以与上面的例子不同。具体采用什么样的编码矩阵可以根据资源单元的个数以及复用的用户数量等因素确定。
发送设备将多用户复用的编码矩阵对应的资源单元作为一个逻辑资源单元组。
例如编码矩阵对应3个资源单元(RE)，则将3个资源单元作为一个单元组VREGl，具体可以参见图1B。
所述发送设备根据所述逻辑资源单元，将数据符号编码后的用户的每组 编码符号进行映射处理时，将数据符号编码后的用户的每组编码符号分别映射到一个逻辑资源单元组中，并将映射到同一个逻辑资源单元组的用户编码符号进行多用户复用处理。
具体地，发送设备将调度后的用户的数据符号根据逻辑资源单元组进行分组，每组对应一个逻辑资源单元组。
其中，每个用户的一组数据符号可以对应同一个逻辑资源单元组。
发送设备根据确定的编码矩阵进行相应的编码后，将编码后的每组数据符号映射到逻辑资源单元组上，并将映射到同一个逻辑资源单元组的用户编码符号进行多用户复用处理。
例如用户n，数据符号组n为An＝[an1+bn1j，an2+bn2j，an3+bn3j]，映射后的VREGn上Bn＝An.*[Cn1，Cn2，Cn3]’，具体可以参见图1C。
可选地，发送设备根据用户的信道状况采用不同的编码率，其中编码率为编码矩阵对应于每个用户的列向量中为1的个数。例如当资源单元组为3时，边缘用户采用[1，1，1]’，中心用户采用[1，0，0]’；当资源单元组为4时，边缘用户采用[1，1，1，1]’，中心用户采用[1，0，0，0]’。具体非正交码字选择取决于网络侧设备实现。
需要说明的是，这里的边缘用户和中心用户除了根据地理位置确定，还可以根据SINR(Signal Interference Noise Ratio，信干噪比)、用户的优先级、用户业务的优先级等方式确定。
在实施中，发送设备根据映射方式，将每个逻辑资源单元组向物理资源块进行映射有多种方式，下面列举几种：
映射方式一、发送设备根据映射方式，将每个逻辑资源单元组映射到逻辑资源块上，并将逻辑资源块映射到物理资源块上；
相应地，所述接收设备根据映射方式，对物理资源块反映射确定逻辑资源块，并将逻辑资源块反映射确定逻辑资源单元组。
对于将逻辑资源块映射到物理资源块上和现有LTE的映射和跳频方式相同。
可选地，逻辑资源单元组所占的RE个数为一个逻辑资源块所占的RE个数的因子。
逻辑资源块承载逻辑资源单元组，单元组的RE个数为资源块的因子可以保证，逻辑资源块的RE数是逻辑资源单元组RE数的整数倍。
对于映射方式一，有2种方式。
1、所述发送设备按照先时域后频域或先频域后时域的顺序，将逻辑资源单元组映射到逻辑资源块上，具体可以参见图1D；
相应地，接收设备按照先时域后频域或先频域后时域的顺序，将逻辑资源块反映射，确定逻辑资源单元组。
需要说明的是，图1D中是未考虑参考符号的映射方式，当存在参考符号时，参考符号的符号不传输任何数据。
2、所述发送设备将各所述逻辑资源单元组进行交织后映射到逻辑资源块上，具体可以参见图1E；
相应地，接收设备对逻辑资源块反映射确定交织后的逻辑资源单元组，对所述交织后的逻辑资源单元组进行解交织确定逻辑资源单元组。
具体交织和解交织过程可以参见3GPP TS 36.212和36.213，在此不再赘述。
映射方式二、发送设备根据映射方式，将每个逻辑资源单元组直接映射到物理资源块上；
相应地，所述接收设备根据映射方式，将物理资源块反映射直接确定逻辑资源单元组。
可选地，逻辑资源单元组所占的RE个数为总物理资源块所占的RE个数的因子。
对于映射方式一，有3种方式。

相应地，接收设备按照先时域后频域或先频域后时域的顺序，对物理资源块反映射确定逻辑资源单元组。
2、发送设备将各所述逻辑资源单元组进行交织后映射到物理资源块上，具体可以参见图1E；
相应地，接收设备对物理资源块反映射确定交织后的逻辑资源单元组， 对所述交织后的逻辑资源单元组进行解交织确定逻辑资源单元组。
具体交织和解交织过程可以参见3GPP TS 36.212和36.213，在此不再赘述。
3、发送设备将各所述逻辑资源单元组进行组间跳频后映射到物理资源块上。
本公开实施例的跳频方法可以应用于交织之后，或者和交织并列，或者不进行交织直接跳频。
1)以交织后进行跳频为例，以时隙(time slot)为时间单位，每个VEG跳固定的距离G＝2，具体可以参见图1H，即逻辑资源单元组3RE，进行交织后，做固定距离的跳频。
跳频的固定距离可以由网络侧配置并通知给终端，终端在反映射时根据固定距离获得资源单元组位置。
2)以不做交织进行跳频为例，以时隙为时间单位，每个VEG跳固定的距离G＝2，具体可以参见图1I，即逻辑资源单元组3RE，不做交织，做固定距离的跳频。
跳频的固定距离可以由网络侧配置并通知给终端，终端在反映射时根据固定距离获得资源单元组位置。
在确定跳频距离时，为保证任何场景下每个逻辑资源单元组的跳频距离相等，跳频距离是逻辑资源块频域上单元组个数的因子。
以上述组间跳频之后的逻辑资源，可以以现有LTE协议中RE映射(RE mapping)的方式向物理资源映射，跳频方式为现有3GPP TS 36.213中的跳频方式。
在实施中，发送设备为接收设备配置所述编码矩阵和所述映射方式；
相应地，接收设备对物理资源块反映射确定进行组间跳频后的逻辑资源单元组，对所述进行组间跳频后的逻辑资源单元组根据组间跳频位置确定逻辑资源单元组。

相应地，接收设备根据发送设备配置的所述编码矩阵和所述映射方式接收数据。
二、上行传输。

例如如果使用N＝3个资源单元，复用7个用户，则可以采用下面的编码矩阵：
Figure PCTCN2015089546-appb-000003
资源单元组可根据信道情况、编码复杂度、开销等进行调整并做规定，例如如果资源单元组为4，用户数为8，则可以采用下面的编码矩阵：

发送设备将多用户复用的编码矩阵对应的资源单元作为一个逻辑资源单元组。
例如编码矩阵对应3个资源单元(RE)，则将3个资源单元作为一个单元组VREG1，具体可以参见图1B。
所述发送设备根据所述逻辑资源单元，将数据符号编码后的用户的每组编码符号进行映射处理时，将数据符号编码后的用户的每组编码符号分别映射到一个逻辑资源单元组中，并将映射到同一个逻辑资源单元组的用户编码符号进行多用户复用处理。
具体地，发送设备将调度后的用户的数据符号根据逻辑资源单元组进行分组，每组对应一个逻辑资源单元组。
其中每个逻辑资源单元组就对应一个用户的每组数据符号。
发送设备根据确定的编码矩阵进行相应的编码后，将编码后的每组数据符号映射到逻辑资源单元组上。
例如用户n，数据符号组n为An＝[an1+bn1j，an2+bn2j，an3+bn3j]，映射后的VREGn上Bn＝An.*[Cn1，Cn2，Cn3]’，具体可以参见图1G。
可选地，发送设备根据用户的信道状况采用不同的编码率，其中编码率为编码矩阵对应于每个用户的列向量中为1的个数。例如当资源单元组为3时，边缘用户采用[1，1，1]’，中心用户采用[1，0，0]’；当资源单元组为4时，边缘用户采用[1，1，1，1]’，中心用户采用[1，0，0，0]’。
