具体实施方式
发明人在研究过程中发现，在实际的无线通信系统中，由于基站与终端之间的无线传播路径容易受到环境的影响，无线信道具有很大的随机性。因此，为了能够在终端准确的恢复基站发送的信号，必须对基站和用户间 的信道信息进行较为准确的估计，利用估计的信道信息计算信道状态信息(Channel State Information，CSI)，并反馈计算的CSI，基站根据用户反馈的CSI进行用户的调度，并传输数据。其中，CSI包括：信道质量指示信息(Channel quality indication，CQI)、预编码矩阵指示符(Precoding Matrix Indicator，PMI)和秩指示符(Rank Indicator，RI)。而另外一方面，用估计的信道对传输的数据区域的信道进行估计，便于对数据进行解调和检测。
在早期的长期演进(Long Term Evolution，LTE)版本，如Release 8(Rel-8)版本中，终端通常采用公共参考信号(Common Reference Signal，CRS)进行CSI估计，并且终端也基于CRS估计PDSCH的信道信息，并对传输的数据进行解调。在长期演进增强(Long Term Evolution-Advanced，LTE-A)的Rel-10版本中，为了使得终端可以对多达8个的天线端口进行估计和反馈更大带宽的CSI，引入了新的RS，即CSI-RS，新引进的CSI-RS是由基站发送的，专门用于进行信道测量的参考信号，终端基于基站发送的导频符号进行CSI估计，获得不同收发天线在不同时频资源位置的信道矩阵H的信息，继而可以基于信道矩阵H进行CSI量化及反馈。并且引入了DMRS用于估计下行共享信道，并对传输的数据进行解调。与早期版本中的CRS既用于CSI估计又用于信号解调不同，这里DMRS和PDSCH使用了相同的预编码，从而基站不需要再向Rel-8版本的基站一样需要通知终端其所使用的预编码，一方面节省了下行信令开销，也能更好地支持多用户的多输入多输出。
为了便于调度和描述，无线通信系统通常将时频资源划分成一个个的物理资源块(比如LTE/LTE-A里的物理资源块(Physical Resource Block，PRB))，每个物理资源块包括多个时域符号、多个频域上的子载波的资源单元(也可叫时频资源，比如，LTE和LTE A中引入的资源单元(Resource Element，RE)的概念)。并且根据物理资源块中的资源单元传输的信号不 同，对物理资源块中的资源单元进行分类，比如用于传输数据相关的导频的资源单元(比如LTE/LTE-A里的DMRS RE，这里称为第一资源单元)，用于传输数据的资源单元(比如LTE/LTE-A里的PDSCH RE，这里称为第二资源单元)，用于传输预编码的下行控制信道的资源单元(比如LTE/LTE-A里的增强下行控制信道(enhance Physical Downlink Control Channel，ePDCCH)，这里称为第三资源)。
在无线传输过程中，目标信号会受到干扰和噪声的影响，在进行信道估计时联合多个时域上的和/或频域上的资源单元信号来估计信道，从而可以提高信道估计的性能。但进行联合信道估计的RE必须是使用相同的预编码信息，否则就不能进行联合信道估计。为了便于终端知道联合区域的大小，可以将使用了相同预编码的多个物理资源块进行绑定，这些使用相同预编码绑定的物理资源块被称为一个预编码资源组(Precoding Resource block Groups，PRGs)，它的大小P′跟系统带宽等因素有关，如表1示出的为LTE/LTE-A中的一种情况。

在PRGs中的P′个PRB里，这里第一资源和第二资源使用的预编码的频域粒度都是P′个PRB。然而，如果DMRS和PDSCH使用了不同的预编码粒度，将无法实现资源绑定。
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。

下面结合具体的场景详述本申请的实施例：
实施方式1
本实施例中描述的方案是基站配置资源绑定的参数包括(即上述的资源绑定参数信息)预编码的频域粒度的情况，基站确定第一资源预编码的频域粒度、第二资源以及第三资源的预编码的频域粒度。
基站可使用基于DMRS的半静态的开环多入多出技术(Multiple-Input Multiple-Output，MIMO)，所谓半静态的开环MIMO是指基站会反馈部分码本的信息，比如第一码本W1，CSI-RS资源索引(CSI-RS resource indicator，CRI)。基站在DMRS上使用预编码W1或者CRI对应的CSI-RS上使用的预编码W1。而PDSCH上使用预编码W(W为W1*W2)，W2取值于一个码本子集合S，S包括L个码字。基站在PRB或子载波组上轮询使用L个W2码字。比如，第i个PRB或者子载波组使用集合S中的第j个码字，其中，j＝mod(i，L)，实际配置中，不局限于这种j和i的关系配置，但让也可以基于子载波组，子载波来轮询，这里不一一例举，只举例说明基于PRB来轮询的方式，上述的“mod(，)”为求余函数。
这样可能导致DMRS和PDSCH的预编码粒度不同，从而需要独立地配置绑定参数。包括但不限于如下方式。
方式1：PDSCH REG的预编码的频域粒度为M2＝1，而DMRS REG的预编码的频域粒度为
Figure PCTCN2017083277-appb-000002
其中，
Figure PCTCN2017083277-appb-000003
为系统带宽。即DMRS REG在整个带宽内使用相同的预编码，绑定粒度为整个系统带宽，而PDSCH REG的预编码的频域粒度为1个PRB，每个PRB都可以使用不同的预编码。
方式2：PDSCH REG的预编码的频域粒度为M2＝1，而DMRS REG的 预编码的频域粒度为
Figure PCTCN2017083277-appb-000004
其中，
Figure PCTCN2017083277-appb-000005
为系统带宽。即DMRS REG的频域粒度为M1，把整个系统带宽分成
Figure PCTCN2017083277-appb-000006
个DMRS预编码资源组PRG。每个DMRS的PRG组内使用相同的预编码，而不同DMRS的PRG组可能使用不同的预编码。而PDSCH REG的预编码的频域粒度为1个PRB，每个PRB都可以使用不同的预编码。这里，“ceil”表示上取整的函数，M1>1。
方式3：PDSCH REG的预编码的频域粒度为M2＝2，而DMRS REG的预编码的频域粒度为

其中，

为系统带宽。即DMRS REG的频域粒度为M1，把整个系统带宽分成
Figure PCTCN2017083277-appb-000009
个DMRS预编码资源组PRG。每个DMRS的PRG组内使用相同的预编码，而不同DMRS的PRG组可能使用不同的预编码。而PDSCH REG的预编码的频域粒度为2个PRB，把整个系统带宽分成了每个PRB都可以使用不同的预编码。
Figure PCTCN2017083277-appb-000010
Figure PCTCN2017083277-appb-000011
个PDSCH PRG。每个PDSCH PRG组内使用相同的预编码，而不同PDSCH PRG组可能使用不同的预编码，这里，ceil表示上取整的函数，M1>M2＝2。且这里M2也可以取大于2的正整数，M2小于M1。
当然，可以配置其它的M1和M2的关系，只要满足M1>M2就可以。
即将DMRS与M1个PRB绑定一起，使用了相同的第一预编码，用户可以在这M1个PRB的域范围进行联合信道估计。PDSCH在M2个PRB内是绑定在一起的，使用了相同的第二预编码。
基站通过第一指令传输DMRS REG的资源绑定参数信息，比如DMRS PRG的预编码的频域粒度M1，第二指令传输PDSCH REG的资源绑定参数信息，比如PDSCH的PRG的预编码的频域粒度M2。
终端接收基站发送的第一指令和第二指令。通过第一指令确定了DMRS PRG的预编码的频域粒度M1，通过第二指令确定了PDSCH PRG的 预编码的频域粒度M2。
需要说明的是，也可以基站只发送一个第四指令(即将上述的用于分别指示各个资源的指令信息集合在一个指令中发送)，用于联合指示DMRS和PDSCH的资源绑定参数信息。终端接收的第四指令，从而获得DMRS和PDSCH的资源绑定参数信息。
另外，在本实施例中，M1>1表示DMRS是绑定使能状态。M2>1表示PDSCH是绑定使能状态，M1＝1表示PDSCH是绑定去使能状态，这相当于跟预编码的频域粒度进行绑定。
在一实施例中，DMRS的绑定状态由第一指令传输给终端，PDSCH的绑定状态由第二指令传输给终端，或者在第四指令上联合传输。
在本实施列中，PDSCH资源也可以替换成第三资源的ePDCCH，其实现过程和PDSCH的类似，也是基站确定PDCCH的频域绑定粒度为M3，并且满足DMRS的频域粒度M1大于M3就可以，且在M3为1时默认为资源绑定去使能的。这里不再赘述。
在本实施列中，PDSCH资源也可以替换成PDSCH和第三资源的ePDCCH共同存在的情况，其实现过程和PDSCH的类似，也是基站确定ePDCCH的频域绑定粒度为M3，并且满足DMRS的频域粒度M1大于M3就可以，M1>M2，这里，M3和M2的关系可以是相等的，也可以是不相等的，即M3>M2，或M2>M3，且在M3为1时默认为资源是绑定去使能的。这里不再赘述。ePDCCH的绑定状态也可以通过第三指令或者第四指令进行传输。
实施方式2
本实施例中描述的方案是基站配置资源绑定的参数包括(即上述的资源绑定参数信息)预编码的时域粒度的情况，基站确定第一资源预编码的频域粒度、第二资源以及第三资源的预编码的时域粒度。
在本实施例中，基站可使用基于DMRS的半静态的开环MIMO，所谓半静态的开环MIMO是指基站会反馈部分码本的信息，比如第一码本W1，CRI。基站在DMRS上使用预编码W1或者CRI对应的CSI-RS上使用的预编码W1。而PDSCH上使用预编码W(W为W1*W2)，W2取值于一个码本子集合S，S包括L个码字。基站在OFDMA符号上或slot上或者TTI(Transmission Time Interval，即传输时间间隔)上，或者子帧，帧上上轮询使用L个W2码字。这里以TTI索引为例说明，比如，第i个TTI使用集合S中的第j个码字，其中，j＝mod(i，L)，实际配置中，不局限于这种和i的关系配置。
这样可能导致DMRS和PDSCH的预编码时域粒度不同，从而需要独立地配置绑定参数。包括但不限于如下方式。
方式1：PDSCH预编码时域粒度为N2＝1，而DMRS预编码时域粒度为N1>1。
方式2：PDSCH的预编码时域粒度为N2>1，而DMRS的预编码时域粒度为N1>N2。
即将DMRS在N1个子帧绑定一起，使用了相同的第一预编码，用户可以在这子帧对应的时域范围进行联合信道估计。PDSCH在N2个子帧内是绑定在一起的，使用了相同的第二预编码。
基站通过第一指令传输DMRS REG的绑定参数配置，比如DMRS的预编码的时域粒度N1，第二指令传输PDSCH的绑定参数配置，比如PDSCH的预编码时域粒度N2。
终端接收基站发送的第一指令和第二指令。通过第一指令确定了DMRS的预编码时域粒度N1，通过第二指令确定了PDSCH的预编码的时域粒度N2。
另外，在本实施例中，N1>1表示DMRS是绑定使能状态。N2>1表示 PDSCH是绑定使能状态，N1＝1表示PDSCH是绑定去使能状态。
在本实施列中，PDSCH资源也可以替换成第三资源的ePDCCH，其实现过程和PDSCH的类似，也是基站确定PDCCH的预编码时域粒度为N3，并且满足DMRS的预编码时域粒度N1大于N3的要求就可以，且在N3为1时，默认为资源是绑定去使能的。这里不再赘述。
在本实施列中，PDSCH资源也可以替换成PDSCH和第三资源的ePDCCH共同存在的情况，其实现过程和PDSCH的类似，也是基站确定ePDCCH的预编码时域粒度为N3，并且满足DMRS的预编码时域粒度N1大于N3就可以，N1>N2，这里，N3和N2的关系可以是相等的，也可以是不相等的，即N3>N2，或N2>N3，且在N3为1时默认为资源绑定去使能的。这里不再赘述。
类似频域粒度的实施方式如实施方式2所描述的，DMRS，PDSCH，ePDCCH的资源绑定参数也可以通过一个第四指令传输给终端，这里不再重复。
实施方式3
本实施例中描述的方案是基站配置资源绑定的参数包括预编码粒度和预编码集合的情况，基站确定第一资源预编码的频域粒度，第二资源和/或第三资源的预编码的频域粒度，以及第一资源的每个绑定的预编码资源组PRG内的预编码取值，第二资源和/或第三资源的每个绑定的预编码资源组PRG中的预编码取值。
在本实施例中，基站可使用基于DMRS的半静态的开环MIMO，所谓半静态的开环MIMO是指基站会反馈部分码本的信息，比如第一码本W1，CRI。基站在DMRS上使用预编码W1或者CRI对应的CSI-RS上使用的预编码W1。而PDSCH上使用预编码W(W＝W1*W2)，W2取值于一个码本子集合S，其中S包括L个码字。基站在PRB或子载波组上轮询使用L个 W2码字。比如，第i个PRB或者子载波组使用集合S中的第j个码字，其中，j＝mod(i，L)，实际配置中，不局限于这种j和i的关系配置。
需要说明的是，在LTE/LTE A的版本Release 8和Release 9中，4天线的码本和2天线的码本是单码字的形式，只有一个PMI，其值表示为i＝1，…，N11，N11为码字的个数。在Release 10的8天线码本和Release 12版本的4天线码本中，是双码本反馈的形式，即码字可以写成W＝W1*W2的形式，而W1是长期反馈的码本，称为第一码本，一般有N11个组，每个组包括了P1个备选波束，用户选择N11个组的一个组索引反馈给基站，这个反馈一般用PMI1来量化和反馈，其值一般用i1＝1，…，N11表示，N11为上述W1的个数；W2表示一个短期反馈的码本，称为第二码本，它的作用是在W1码字里选择P1个备选波束里的一个，并为同一个数据层的每个极化方向选择的波束选择极化相位Co-phasing，W2里的每个码字用PMI2量化和反馈，其值为i2＝1，…，P1，P1为W2的个数。
在Release 12版本以前的码字都是针对1D天线(即具有一个维度的天线)阵列的，属于1D的码字，在Release 13版本的码本里，由于使用了更多的天线，码本的维度变得更大了。天线的拓扑一般也是平面阵列的，即有两个维度方向的天线(如水平维度和垂直维度)，从而设计了2D的码字。从而第一码本W1里的每个波束具有2维的形式

其中，vm和un分别为第一维度和第二维度的离散傅里叶矢量(Discrete Fourier Transform，DFT)，

以及不同极化方向的Co-phasing，对应的码字索引为PMI2，用i2＝1，…，P1表示。
而在CSI反馈类别为Class B，在K>1时，基站会配置K套CSI-RS resource(即CSI-RS资源)，每个CSI-RS resource有独立配置的端口个数，RE图样，导频序列，预编码方向。每个CSI-RS resource对应一个索引，相应的对应了一个方向的预编码向量。这个CSI-RS resource对应的索引为CRI，反馈CRI就知道其使用的预编码了，用户在基于选择的CRI对应的CSI-RS resource上进行CSI计算反馈。
这样可能导致DMRS和PDSCH的预编码粒度不同了，从而需要独立地配置绑定参数。包括但不限于如下方式。
方式1：PDSCH REG的预编码的频域粒度为M2＝1，而DMRS REG的预编码的频域粒度为

个PDSCH PRG。每个PDSCH PRG组内使用相同的预编码，而不同PDSCH PRG组可能使用不同的预编码，这里，ceil表示上取整的函数，M1>M2＝2。且这里M2也可以取大于2的正整数，M2小于M1。
基站对于L1个DMRS REG里的第j个PRG中使用预编码W1j，假设PRG中的PRB索引J为取值于集合S1＝{(j-1)*M+1≤J≤j*M}，对于L2个PDSCH REG里的第i个PRG中使用预编码W2i，假设PRG中的PRB索引I为取值于集合S2＝{(i-1)*N+1≤I≤j*N}。如果S2属于S1，那么集合S2里索引对应的PRB中PDSCH使用的预编码为W1jW2i。其中W1j也可以只是包括一个维度的码字信息，比如第一维度的码字信息vm，其的形式为

的形式，I2为单位矩阵，其维度使得矩阵
Figure PCTCN2017083277-appb-000026
的列数与W2i的行数相同。比如第二维度的码字信息un，其的形式为

的形式，I1为单位矩阵，其维度使得矩阵
Figure PCTCN2017083277-appb-000028
的列数与W2i的行数相同。这里，j＝1，…，L1，i＝1，…，L2。
基站通过第一指令传输DMRS REG的绑定参数配置，比如DMRS PRG的预编码的频域粒度M1，第二指令传输PDSCH REG的绑定参数配置，比如PUSCH的PRG的预编码的频域粒度M2。
终端接收基站发送的第一指令和第二指令。通过第一指令确定了DMRS PRG的预编码的频域粒度M1，通过第二指令确定了PDSCH PRG的预编码的频域粒度M2。
在一实施例中，终端在确定DMRS PRG的预编码粒度M1后，对于第j个绑定的DMRS PRG，对其中包括的M1个PRB，利用M1个PRB里的所有DMRS端口对信道进行联合信道估计，从而提高信道的估计准确性。这里，假设估计的M1个PRB的信道为H1。它是基站到用户的信道H经过预编码W1j后的等效信道，j＝1，…，L1。
在一实施例中，终端在确定PDSCH PRG的预编码粒度M2后，对于i个绑定的PDSCH PRG，对其中包括的M2个PRB，并根据PRB的索引知道M2个PRB使用的W2i信息。从而，将DMRS PRG中估计的信道H1乘以W2的到M2个PRB里的PDSCH上的信道估计H2，利用H2对M2个PRB的PDSCH进行数据检测和解调，i＝1，…，L2。
这里只是以PRB为频域单元粒度，当然也可以是其它的，比如PRB组，子带，子载波，子载波组为频域单元粒度，其过程类似，这里不一一例举。
在本实施例中，PDSCH的预编码来自第二集合码字，第二集合码字包括的码字的形式为W1*W2，而DMRS的预编码来自第一集合码字，第一集合码字包括的码字的形式为W1。
在本实施例中，PDSCH的预编码来自第二集合码字和第一码本集合，第二集合码字包括的码字的形式为W2，而DMRS的预编码来自第一集合码字，第一集合码字包括的码字的形式为W1。即PDSCH取第一码本集合中的码字W1和第二码本集合的W2构成使用的码字W1*W2。
在本实施列中，PDSCH资源也可以替换成第三资源的ePDCCH，其实现过程和PDSCH的类似，也是基站确定ePDCCH的预编码粒度M3和预编码W’，并且在M3个PRB里使用预编码W’＝W1*W2，它在M3个PRB内保持不变，它的取值来自第三预编码集合(其中的码字的形式为W1*W2)，或者第三预编码集合只有码字形式W2，而ePDCCH取值于第一码本集合的W1和第三码本集合的W2，形成自己的码字。这里不再赘述。
在本实施列中，PDSCH资源也可以替换成PDSCH和第三资源的ePDCCH共同存在的情况，其实现过程和PDSCH的类似，也是基站确定ePDCCH的预编码粒度M3和预编码W’，并且在M3个PRB里使用预编码W’＝W1*W2，它在M3个PRB内保持不变，其中ePDCCH和PDSCH的预编码取值可以是相同的，也可以不同。这里不再赘述。
需要说明的时，这里举例说明的是频域上使用预编码的情况，预编码同样可以在时域上轮询使用，比如在不同N1个TTI(同样可以是时域符号，子帧，系统帧，slot等)上DMRS使用预编码W1，而在N2个TTI内，PDSCH使用相同的预编码W＝W1*W2，在而在N3个TTI内ePDCCH使用预编码W’＝W1’*W2’，其中W和W’可以相同也可以不同。
同样地，PDSCH，ePDCCH，DMRS对应的资源绑定参数信息也可以只通过一个第四指令进行传输。
