通过上述实施例，对目标数量的频域资源块进行分组之后，不同组之间频域资源块带宽可以不相同，可以使用不同参数的波形函数进行加窗或滤波。另外，由于子载波间隔可以都相等，因此与另一组相邻的频域资源块的带宽可以不相等，但可以通过过采样方式采用相同的IFFT点数进行傅里叶变换，相邻组分别进行数据处理后各组之间不会有干扰。因此，有效解决相关技术中存在的数据干扰问题。
下面结合具体实施例对本公开进行说明：
具体实施例一：
待传输数据在N个频域资源块中传输，所述N个资源块分别包含k(n)个子载波，且所述N个资源块的子载波间隔相等。在本实施例中，N个资源块的带宽都相等，N个资源块包含的子载波个数相等，并且k(n)＝4，如图3所示。
在本实施例中，以将这N个频域资源块分成2组为例进行说明(当然，在实际应用中，还可以分成更多组，例如，3组、5组、10组等等，本实施例以分成2组为例)，这2组频域资源块在频域连续分布，即所述N个频域资源块在频域连续分布，如图3所示。这2组包含的资源块个数分别为N(1)和N(2)，N(1)＝3，N(2)＝3，N(1)+N(2)＝N。
分别对每组里的N(m)个频域资源块上的所述待传输数据分别进行处理以形成N(m)组数 据序列。在本实施例中，对每组的所有N(m)个频域资源块上的所述待传输数据都进行傅里叶逆变换(IFFT或IDFT)，每组形成N(m)组数据序列。也就是说，在本实施例中，对N个频域资源块上的所述待传输数据分别进行傅里叶逆变换，形成N组数据序列。所述傅里叶逆变换为过采样傅里叶逆变换或者为非过采样傅里叶逆变换，所述傅里叶逆变换的IFFT(或者IDFT)点数大于等于4，所述傅里叶逆变换操作时对应的零频是在本频域资源块范围内。
然后对每组的所述N(m)组数据序列分别进行处理，每组都形成一组数据序列。在本实施例中，对第一组的N(1)组数据序列进行傅里叶逆变换，形成一组数据序列S1；对第二组的N(2)组数据序列进行傅里叶逆变换，形成一组数据序列S2。所述傅里叶逆变换为：每N(m)个数据进行一个所述傅里叶逆变换，所述每N(m)个数据分别来自于N(m)组数据序列。比如，N(m)组数据序列分别在N(m)行，然后按照列取出N(m)个数据，对取出的每N(m)个数据进行一个所述傅里叶逆变换。所述每N(m)个数据进行一个所述傅里叶逆变换，还包括增加多组零数据，然后进行傅里叶逆变换，所述傅里叶逆变换的IFFT点数大于N(m)。每N(m)个数据进行一个所述傅里叶逆变换形成一个时域数据序列，多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S1或S2，或者多个所述傅里叶逆变换生成的时域数据序列重复后再串行连接形成数据序列S1或S2。
以第一组的N(1)个频域资源块上的所述待传输数据的处理为例进行说明。假设每个资源块的4个子载波上的待传输数据分别为：[A1，A2，A3，A4]，[B1，B2，B3，B4]，[C1，C2，C3，C4]。分别添加4个零后的3组数据分别为[0，0，A1，A2，A3，A4，0，0]，[0，0，B1，B2，B3，B4，0，0]，[0，0，C1，C2，C3，C4，0，0]。分别对每个资源块的待传输数据进行8点的过采样傅里叶逆变换，形成3组时域数据序列分别为[a1，a2，a3，a4，a5，a6，a7，a8]，[b1，b2，b3，b4，b5，b6，b7，b8]，[c1，c2，c3，c4，c5，c6，c7，c8]。然后对所述3组时域数据序列进行多个过采样傅里叶逆变换，假设所述傅里叶逆变换的点数为16。假设对[a1，b1，c1]进行16点的IFFT后形成的第1组数据为[D1-1，D1-2，D1-3，D1-4，D1-5，D1-6，D1-7，D1-8，D1-9，D1-10，D1-11，D1-12，D1-13，D1-14，D1-15，D1-16]，对[a2，b2，c2]进行16点的IFFT后形成的第2组数据为[D2-1，D2-2，D2-3，D2-4，D2-5，D2-6，D2-7，D2-8，D2-9，D2-10，D2-11，D2-12，D2-13，D2-14，D2-15，D2-16]，依次类推，对[a8，b8，c8]进行16点的IFFT后形成的第8组数据为[D8-1，D8-2，D8-3，D8-4，D8-5，D8-6，D8-7，D8-8，D8-9，D8-10，D8-11，D8-12，D8-13，D8-14，D8-15，D8-16]，将这8组数据序列串行链接后形成一组时域数据序列S1。同理，对第二组的N(2)个频域资源块上的所述待传输数据进行类似的处理形成一组时域数据序列S2。
然后对数据序列S1和数据序列S2进行处理以形成一组数据序列中，所述处理包括：对数据序列S1进行滤波或加窗、对数据序列2进行滤波或加窗、点乘操作、加操作。由于第一组与第二组的频域资源块带宽相同，因此数据序列S1与S2分别进行多相滤波操作时所使用的波形函数相同。点乘操作可以对数据序列S1进行点乘操作，也可以对数据序列S2进行点乘操作。本实施例中，数据序列S2进行多相滤波操作之后，再与序列ejθi(其中，i＝0，1，2，...)进行点乘后，然后与数据序列S1进行多相滤波操作后的序列进行加操作，形成一组时域数据序列。进而传输一组时域数据序列。
具体实施例二：
待传输数据在N个频域资源块中传输，所述N个资源块分别包含k(n)个子载波，且所述 N个资源块的子载波间隔相等。将这N个频域资源块分成2组(同样地，该实施例也是以将N个资源块分成2组为例进行说明的，在实际应用中，还可以分成更多组，例如，3组、5组、10组等等)，这2组频域资源块在频域连续分布，即所述N个频域资源块在频域连续分布，如图4所示。在本实施例中，这2组包含的资源块个数分别为N(1)和N(2)，N(1)＝3，N(2)＝3，N(1)+N(2)＝N。所述2组中至少一组内，N(m)个频域资源块的带宽不全相等。本实施例中，第二组的N(2)个资源块的带宽都相等，第二组的N(2)个资源块包含的子载波个数相等，并且k(n)＝16；第一组的N(1)个资源块中，与第二组相邻的资源块带宽与其他资源块带宽不相等，第二组相邻的资源块包含的子载波个数为8，而其他资源块包含的子载波个数都为16，具体可参见如图4。
在本实施例中可以分别对每组里的N(m)个频域资源块上的所述待传输数据分别进行处理以形成N(m)组数据序列。在本实施例中，对每组的所有N(m)个频域资源块上的所述待传输数据都进行傅里叶逆变换(IFFT或IDFT)，每组形成N(m)组数据序列。也就是说，在本实施例中，对N个频域资源块上的所述待传输数据分别进行傅里叶逆变换，形成N组数据序列。所述傅里叶逆变换为过采样傅里叶逆变换或者为非过采样傅里叶逆变换，所述傅里叶逆变换的IFFT(或者IDFT)点数大于等于16，所述傅里叶逆变换操作时对应的零频是在本频域资源块范围内。所述2组中至少一组内，N(m)个频域资源块的带宽不全相等但所述IFFT点数都相等。
然后对每组的所述N(m)组数据序列分别进行处理，每组都形成一组数据序列。在本实施例中，对第一组的N(1)组数据序列进行傅里叶逆变换，形成一组数据序列S1；对第二组的N(2)组数据序列进行傅里叶逆变换，形成一组数据序列S2。所述傅里叶逆变换为：每N(m)个数据进行一个所述傅里叶逆变换，所述每N(m)个数据分别来自于N(m)组数据序列。比如，N(m)组数据序列分别在N(m)行，然后按照列取出N(m)个数据，对取出的每N(m)个数据进行一个所述傅里叶逆变换。所述每N(m)个数据进行一个所述傅里叶逆变换，还包括增加多组零数据，然后进行傅里叶逆变换，所述傅里叶逆变换的IFFT点数大于N(m)。每N(m)个数据进行一个所述傅里叶逆变换形成一个时域数据序列，多个所述傅里叶逆变换生成的时域数据序列串行连接形成数据序列S1或S2，或者多个所述傅里叶逆变换生成的时域数据序列重复后再串行连接形成数据序列S1或S2。
然后对数据序列S1和数据序列S2进行处理以形成一组数据序列中，所述处理包括：对数据序列S1进行滤波或加窗、对数据序列2进行滤波或加窗、点乘操作、加操作。虽然频域资源块带宽并不是都相等，但由于第一组与第二组的每个频域资源块上所述待传输数据的傅里叶逆变换IFFT点数相同，因此数据序列S1与S2分别进行多相滤波操作时所使用的波形函数相同。点乘操作可以对数据序列S1进行点乘操作，也可以对数据序列S2进行点乘操作。本实施例中，数据序列S2进行多相滤波操作之后，再与序列ejθi(其中，i＝0，1，2，...)进行点乘后，然后与数据序列S1进行多相滤波操作后的序列进行加操作，形成一组时域数据序列。然后传输一组时域数据序列。
具体实施例三：
如图5所示，传输所述一组时域数据序列，还包括，对所述一组时域数据序列进行加窗或滤波、数模转换DAC、射频链路RF传输过程。如果在形成一组时域数据序列之前进行加窗或滤波操作，则这里可以不对所述一组时域数据序列进行加窗或滤波。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
