可选地，终端设备的天线端口和网络设备的天线端口之间可基于SRS资源配置信息指示的SRS资源配置在相应的资源上传输SRS。
本申请不对天线端口的名称进行限定，例如，天线端口也可以称为参考信号端口。
第二，重复因子、扫描带宽、跳频带宽、发送带宽、跳频周期和频率缩放因子PF：
重复因子R∈{1,2,4}由网络设备通过高层参数(例如repetitionFactor)半静态配置。一次参考信号发送对应一个参考信号资源内的连续R个OFDM符号，一次参考信号发送对应的连续R个OFDM符号中的第一个OFDM符号在参考信号资源内的编号能够被R整除。

例如，长度为N的ZC序列可以表示为如下公式：其中，q为ZC序列的根指标，q为与N互质且小于N的正整数。n＝0,1,…,N-1，j为虚数单位，exp()为以自然常数e为底的指数函数。
在一些实施例中，天线端口pi对应的循环移位αi满足下述公式(1)。

表1

第四，梳齿(comb)、梳齿数量KTC、梳齿偏移量
示例性地，频域资源可以划分为多个梳状频域资源组，一个梳状频域资源组可以为一把梳齿。
示例性地，梳齿数量可以为参考信号的发送带宽中包括的梳齿数量。
可选地，梳齿数量也可以称为梳齿度，本申请对此不限定。
可选地，可以根据梳齿数量获得一把梳齿上任意两个相邻子载波之间间隔的子载波数量。
例如，梳齿数量KTC可以等于2、4、或8等。
可选地，梳齿数量可以由网络设备通过高层参数半静态配置。
图3示出了梳齿数量KTC为2、4、或8时分别对应的频域资源的划分。以梳齿数量KTC＝2为例，偶数子载波(例如编号为0,2,4…的子载波)组成一个梳状频域资源组，奇数子载波(例如编号为1,3,5…的子载波)组成一个梳状频域资源组。每个格子表示一个资源元素(resource element，RE)，一个OFDM符号和一个子载波组成一个RE。
示例性地，梳齿偏移量为参考信号占用的梳齿的参考量。
一些实施例中，天线端口pi的占用的梳齿的索引满足下述公式(2)。
在上述公式(2)中，表示梳齿偏移量，
可选地，梳齿偏移量可以是由网络设备通过高层参数(例如传输梳齿(transmissionComb))配置的。
第五，部分探测偏移量
一些实施例中，天线端口pi的频域起始位置可满足下述公式(3)。
上述公式(3)中，满足其中，为每个资源块包含的子载波数量，例如为12。表示天线端口pi的占用的梳齿的索引。

上述公式(4)中，为每个资源块包含的子载波数量。表示跳频带宽，为根据高层参数BSRS和CSRS及协议预定义表格确定的跳频带宽。kF为部分探测起始位置索引，kF∈{0,1,…,PF-1}。khop表示起始资源块跳变偏移量。PF表示频率缩放因子。
可选地，部分探测起始位置索引可以是由网络设备通过高层参数(例如
startRBIndexFScaling-r17)半静态配置的。
一些实施例中，起始资源块跳变偏移量khop由下述公式(5)和表2定义。例如，根据下述公式(5)确定的取值，根据的取值和表2确定khop。
上述公式(5)中，表示参考信号对应的跳频周期的索引，PF表示频率缩放因子。其中，数学符号表示向下取整，nSRS表示参考信号(例如SRS)计数值，例如，nSRS表示当前参考信号发送对应的发送次数索引。数学符号∏表示累乘，b′表示跳频层索引。bhop表示起始跳频层索引，bhop∈{0,1,2,3}。BSRS表示终止跳频层索引，BSRS∈{0,1,2,3}。Nb′表示第b′层的并列分支数。
上述公式(5)中，表示一个跳频周期包含的参考信号发送次数。
可选地，bhop和BSRS可以决定跳频的层索引范围，bhop和BSRS均由网络设备通过高层参数(例如freqHopping)半静态配置。
可选地，Nb′可由高层参数BSRS和CSRS及协议预定义表格决定。其中，
表2
下面结合协议预定义表格对CSRS、BSRS、bhop及Nb′进行举例说明。
表3为协议预定义表格，假设网络设备通过高层参数半静态配置CSRS＝12、BSRS＝3、和bhop＝1，则网络设备和终端设备可以通过表3的行索引为12的行以及列索引为BSRS＝1(即BSRS＝bhop)的列确定参考信号的发送带宽为通过表3的行索引为12的行及列索引为BSRS＝3(即BSRS＝BSRS)的列确定参考信号的跳频带宽为从bhop＝1及BSRS＝3可得，该配置下的跳频从第1层开始到第3层结束，则一个参考信号跳频周期包含的参考信号发送次数为第2层的并列分支数N2＝2与第3层的并列分支数N3＝2的乘积2*2＝4。
需要说明的是，注意到在上述计算一个参考信号跳频周期包含的参考信号发送次数的公式中还考虑了起始跳频层索引bhop对应的层中的并列分支数但由于公式 的限制，一个参考信号跳频周期包含的参考信号发送次数并不会因为根据表格得到的的取值而发生改变。规定的原因是计算一个参考信号跳频周期包含的参考信号发送次数时只需要计算起始跳频层之后的层中的并列分支数。
表3


对同一个基序列进行不同的循环移位，例如α1和α2，可以得到不同的序列。当α1和α2满足α1mod 2π≠α2mod 2π时，由基序列和循环移位α1得到的序列与由基序列ru,v(n)和循环移位α2得到的序列是相互正交的，即互相关系数为零。
示例性地，长度为M的序列r1(m)和r2(m)(m＝0,1,…,M-1)的互相关系数可表示为：
网络设备可以将基于同一个基序列和不同循环移位值得到的序列分配给不同的终端设备，这些不同的终端设备可以在相同的时频资源上发送由这些序列(基于同一个基序列和不同循环移位值得到的序列)生成的参考信号，这些序列之间相互正交，当终端设备与网络设备之间的信道在序列长度内平坦时，终端设备之间不会产生干扰。
根据不同的基序列(无论采用相同或不同的循环移位值)获得的序列之间不正交，终端设备可以在相同的时频资源上发送由这些序列(根据不同的基序列获得的序列)生成的参考信号，当终端设备与网络设备之间的信道在序列长度内平坦时，会产生干扰。
示例性地，假设小区1包括UE1和UE2，小区2包括UE3和UE4，UE1使用基序列r1和循环移位值α1生成参考信号并发送，UE2使用基序列r1和循环移位值α2生成参考信号并发送，UE3使用基序列r2和循环移位值α3生成参考信号并发送，UE4使用基序列r2和循环移位值α4生成参考信号并发送，如表4所示。
表4
在某个发送时刻，UE1至UE4可以在相同的时频资源上发送参考信号。假设UE1至UE4与网络设备之间的信道在参考信号占用的M个子载波上平坦，且分别为h1、h2、h3和h4。在参考信号占用的M个子载波中的第m个子载波上，网络设备的接收信号y(m)为
网络设备可以将接收信号y(m)与UE1使用的序列进行如下操作，获得UE1的信道h1：
其中，为UE3对UE1的信道估计产生的干扰，为UE4对UE1的信道估计产生的干扰。可以看出，UE3与UE1之间的干扰会受到循环移位值之间的差值(α3-α1)的影响，UE4与UE1之间的干扰类似。
如此，在相同的时频资源上发送参考信号时，使用相同基序列的终端设备之间不会产生干扰，使用不同基序列的终端设备之间会产生干扰，且干扰会受循环移位值的影响。
在一些实施例中，天线端口pi的占用的梳齿的索引满足上述公式(2)。根据公式(2)获得天线端口pi的占用的梳齿的索引后，可以得出，如果高层参数(例如梳齿偏移量梳齿数量KTC)不发生变化，则在不同的发送时刻，每个天线端口占用的梳齿是恒定的，某个天线端口总会受到相同天线端口的干扰，这样并不利于干扰随机化。
示例性地，结合表5和图4，场景1：小区1包括UE1、UE2、UE3和UE4，每个UE均包括4个天线端口(例如分别为天线端口p0、天线端口p1、天线端口p2和天线端口p3)，UE1、UE2、UE3和UE4的各个天线端口使用基序列r1和各个天线端口对应的循环移位值生成参考信号，UE1、UE2、UE3和UE4的各个天线端口占用的梳齿和使用的循环移位值至少有一个不同，例如占用的梳齿不同，和/或使用的循环移位值不同。小区2包括UE5、UE6、UE7和UE8，每个UE均包括4个天线端口(例如分别为天线端口p0、天线端口p1、天线端口p2和天线端口p3)，UE5、UE6、UE7和UE8使用基序列r2和各个天线端口对应的循环移位值生成参考信号，UE5、UE6、UE7和UE8的各个天线端口占用的梳齿和使用的循环移位值至少有一个不同，例如占用的梳齿不同，和/或使用的循环移位值不同。如图4所示，频域资源被划分为4把梳齿(梳齿1、梳齿2、梳齿3和梳齿4)，图4中每个格子表示一个RE，不同填充的格子表示不同的梳齿，梳齿数量KTC＝4。由于同一小区内的UE的各个天线端口使用相同的基序列和不同的循环移位值生成参考信号，或者，使用相同的基序列和占用不同的梳齿生成并发送参考信号，或者，使用相同的基序列和不同的循环移位值和占用不同的梳齿生成并发送参考信号，所以同一小区内的UE的各个天线端口之间相互正交，同一小区内的UE的天线端口之间没有干扰。
需要说明的是，本申请只是以此场景1为例对本申请提供的方法进行阐述，本申请不对应用的场景进行限定，不对小区数量、小区包括的UE数量、每个UE包括的天线端口数量、以及梳齿数量等进行限定。
表5
根据公式(2)可获得UE1至UE8各个天线端口占用的梳齿。
具体地，UE1至UE8中，每个UE的4个天线端口使用2把梳齿，每两个天线端口使用1把梳齿，共有4把梳齿，有4个终端设备可以在相同的2把梳齿上发送参考信号，每个UE的两个天线端口占用一把梳齿，如表5和图4所示，UE1、UE2、UE5和UE6的天线端口共同占用梳齿1和梳齿3，UE3、UE4、UE7和UE8的天线端口共同占用梳齿2和梳齿4，每个UE的具体哪两个天线端口占用哪一把梳齿发送参考信号是固定的。
例如，以每个UE的天线端口p0和天线端口p2占用一把梳齿，天线端口p1和天线端口p3 占用一把梳齿为例，例如天线端口p0和天线端口p2占用的梳齿为该UE占用的两把梳齿中梳齿索引最小的梳齿，天线端口p1和天线端口p3占用的梳齿为该UE占用的两把梳齿中梳齿索引较大的梳齿。UE1的天线端口p0和天线端口p2占用梳齿1，UE1的天线端口p1和天线端口p3占用梳齿3，UE3的天线端口p0和天线端口p2占用梳齿2，UE3的天线端口p1和天线端口p3占用梳齿4，不一一阐述。为了便于理解，表5和图4中示出了UE和对应的基序列和对应的梳齿，并未示出天线端口。
需要说明的是，梳齿索引也可以称为梳齿编号，本申请对此不限定。
如此，在任意发送时刻，每个UE均会按照表5和图4所示的方式发送参考信号，UE1与UE2、UE5和UE6的各个天线端口使用相同的梳齿发送参考信号，UE1与UE5和UE6的各个天线端口之间使用不同的基序列生成参考信号，UE1与UE5和UE6之间存在干扰。
本申请实施例中，发送时刻指发送参考信号的时刻。
然而，在任意发送时刻，每个UE的每个天线端口占用的梳齿是恒定的，如表5和图4所示，这使在任意发送时刻一个UE的天线端口都会受到相同UE的相同天线端口干扰，结合表5和图4，在任意发送时刻UE1的天线端口都会受到UE5和UE6的天线端口的干扰，具体地，UE1的天线端口p0和天线端口p2在任意发送时刻都会受UE5的天线端口p0和天线端口p2、以及UE6的天线端口p0和天线端口p2的干扰，UE1的天线端口p1和天线端口p2在任意发送时刻都会受UE5的天线端口p1和天线端口p2、以及UE6的天线端口p1和天线端口p2的干扰，其他UE类似，不一一赘述。如此，在多次参考信号发送期间，干扰会呈现一定的规律性，这样并不利于干扰随机化，不利于信道估计。
下面将结合图5-图12对本申请实施例提供的通信方法进行具体阐述。其中，本申请各实施例之间涉及的动作，术语等均可以相互参考，不予限制。本申请实施例中的对象名称或参数名称等只是一个示例，具体实现中也可以采用其他的名称，不予限制。

其中，NC＝1600，x1(n)基于x1(0)＝1,x1(n)＝0,n＝1,2,...,30做初始化，x2(n)根据做初始化。

示例性地，同一个服务小区内的终端设备的第一配置参数相同，不同服务小区内的终端设备的第一配置参数不同。
在一种可能的设计方法中，第一偏移量至少是根据小区标识和第一天线端口占用的时域资源确定的，第一偏移量还可以根据以下参数中的一个或多个确定：每个系统帧包含的时隙数量、每个时隙包含的正交频分复用OFDM符号数量、梳齿数量和梳齿偏移量。
可选地，第一天线端口占用的时域资源可以包括一个或多个OFDM符号。一个或多个OFDM符号是根据以下参数中的一个或多个确定的：第一天线端口对应的系统帧号、第一天线端口对应的时隙编号和第一天线端口对应的OFDM符号编号。
也就是说，本申请不限定第一天线端口占用的时域资源包括的OFDM符号的数量。

可选地，终端设备包括的所有第一天线端口属于同一个参考信号资源，终端设备包括的所有第二天线端口属于同一个参考信号资源，所有第一天线端口属于的参考信号资源与所有第二天线端口属于的参考信号资源可以相同或不同。
一些实施例中，第一偏移量可以为第一随机数。
也就是说，第一偏移量可以为随机数，例如第一偏移量为大于0的随机数。
可选地，第一偏移量或第一随机数可以满足公式(6)、公式(7)、公式(8)、或公式(9)。

需要说明的是，上述公式(6)、公式(7)、公式(8)、或公式(9)中的m与序列长度M无关，上述公式(6)、公式(7)、公式(8)、或公式(9)中的以m的取0至7之间的整数为例进行阐述，本申请对上述公式(6)、公式(7)、公式(8)、或公式(9)中的m的取值范围不进行限定。
本申请通过采用第一偏移量确定终端设备的第一天线端口占用的梳齿，可以使不同发送时刻终端设备占用的频域资源(梳齿)随机变化，从而使对该终端设备造成干扰的终端设备随机变化，实现了频域干扰随机化，能够达到更好的干扰随机化效果。
一些实施例中，根据梳齿数量、梳齿偏移量和第一偏移量确定的天线端口pi的占用的梳齿的索引可以满足下述公式：或者， 其中，表示梳齿偏移量，KTC表示梳齿数量，Q1表示第一偏移量。

下面结合表6和图6对至少根据第一偏移量确定第一天线端口占用的梳齿后每个终端设备的天线端口占用的梳齿进行阐述。
以上述场景1为例，至少根据第一偏移量确定UE1至UE8的每一个天线端口(天线端口p0至天线端口p3)占用的梳齿，每个UE的天线端口占用的梳齿可以如表6和图6所示。
在发送时刻1，UE1、UE2、UE5和UE6的天线端口占用梳齿1和梳齿3，UE3、UE4、UE7和UE8的天线端口占用相同的梳齿2和梳齿4。以UE1为例，UE1的天线端口在梳齿1和梳齿3上会受到UE5和UE6的天线端口的干扰。
需要说明的是，表6和图6中，以每个UE的天线端口p0和天线端口p2占用一把梳齿，天线端口p1和天线端口p3占用一把梳齿为例，例如天线端口p0和天线端口p2占用的梳齿为该UE占用的两把梳齿中梳齿索引最小的梳齿，天线端口p1和天线端口p3占用的梳齿为该UE占用的两把梳齿中梳齿索引较大的梳齿。为了便于理解，表6和图6中示出了UE和对应的基序列和对应的梳齿，并未示出天线端口。
在发送时刻2，UE1、UE2、UE7和UE8的天线端口占用梳齿1和梳齿3，UE3、UE4、UE5和UE6的天线端口占用梳齿2和梳齿4。UE1的天线端口在梳齿1和梳齿3上会受到UE7和UE8的天线端口的干扰。
在发送时刻n，UE1、UE2、UE7和UE8的天线端口占用梳齿2和梳齿4，UE3、 UE4、UE5和UE6的天线端口占用梳齿7和梳齿8，UE1的天线端口在梳齿2和梳齿4上会受到UE7和UE8的天线端口的干扰。
表6
如此，在不同的发送时刻，UE1的天线端口占用的频域资源(梳齿)是随机变化的，从而使对UE1造成干扰的UE是随机变化的，某些发送时刻是UE5和UE6，某些发送时刻是UE7和UE8，对UE1的天线端口造成干扰的天线端口是随机变化的，从而能够达到更好的干扰随机化效果。
在一种可能的设计方法中，M个天线端口还可以包括至少一个第二天线端口。
可选地，第二天线端口可以是终端设备的任一个天线端口。
例如，结合上述场景1，终端设备为UE1，UE1的天线端口p0和天线端口p2可以为第一天线端口，UE1的天线端口p1和天线端口p3可以为第二天线端口。
可选地，第二天线端口占用的梳齿可以至少是根据第二偏移量Q2确定的。
可选地，第二偏移量Q2与第一偏移量不同。

下面结合表7和图7对至少根据第一偏移量或第二偏移量确定不同天线端口占用的梳齿后，每个终端设备的天线端口占用的梳齿进行阐述。
以上述场景1为例，以至少根据第一偏移量确定UE1至UE8的两个天线端口占用的梳齿，至少根据第二偏移量确定UE1至UE8的另外两个天线端口占用的梳齿为例，每个UE的天线端口占用的梳齿可以如表7和图7所示。
在发送时刻1，UE1、UE2、UE5和UE6的天线端口占用梳齿1和梳齿3，UE3、UE4、UE7和UE8的天线端口占用相同的梳齿2和梳齿4。
以UE1为例，在发送时刻1，UE1的天线端口在梳齿1和梳齿3上会受到UE5和UE6的天线端口的干扰。
需要说明的是，表7和图7中，以每个UE的天线端口p0和天线端口p2占用一把梳齿，天线端口p1和天线端口p3占用一把梳齿为例，例如天线端口p0和天线端口p2占用的梳齿为该UE占用的两把梳齿中梳齿索引最小的梳齿，天线端口p1和天线端口p3占用的梳齿为该UE占用的两把梳齿中梳齿索引较大的梳齿。为了便于理解，表7和图7中示出了UE和对应的基序列和对应的梳齿，并未示出天线端口。
在发送时刻2，UE1、UE2、UE7和UE8的天线端口占用梳齿1，UE1、UE2、UE5和UE6的天线端口占用梳齿2，UE3、UE4、UE7和UE8的天线端口占用梳齿3，UE3、UE4、UE5和UE6的天线端口占用梳齿4。
以UE1为例，在发送时刻2，UE1的天线端口(例如天线端口p0和天线端口p2)在梳齿1上会受到UE7和UE8的天线端口(例如天线端口p0和天线端口p2)的干扰，UE1的天线端口(例如天线端口p1和天线端口p3)在梳齿2上会受到UE5和UE6的天线端口(例如天线端口p0和天线端口p2)的干扰。
在发送时刻n，UE1、UE2、UE7和UE8的天线端口占用梳齿1，UE1、UE2、UE5和UE6的天线端口占用梳齿4，UE3、UE4、UE5和UE6的天线端口共同占用梳齿2，UE3、UE4、UE7和UE8的天线端口占用梳齿4。
以UE1为例，在发送时刻n，UE1的天线端口(例如天线端口p0和天线端口p2)在梳齿1上会受到UE7和UE8的天线端口(例如天线端口p0和天线端口p2)的干扰，UE1的天线端口(例如天线端口p1和天线端口p3)在梳齿4上会受到UE5和UE6的天线端口(例如天线端口p0和天线端口p2)的干扰。
表7
如此，至少根据第一偏移量确定UE1至UE8的两个天线端口占用的梳齿，至少根据第二偏移量确定UE1至UE8的另外两个天线端口占用的梳齿后，在不同的发送时刻，UE1的天线端口占用的梳齿会随机变化，例如，发送时刻1，UE1采用梳齿1和梳齿3发送参考信号；发送时刻2，UE1采用梳齿1和梳齿4发送参考信号，使对UE1的天线端口造成干扰的天线端口是随机变化的。并且在相同发送时刻对终端设备的占用不同梳齿的天线端口(UE1的天线端口p0和天线端口p2、以及UE1的天线端口p1和天线端口p3)造成干扰的天线端口可以不是同一个终端设备的天线端口，例如，在发送时刻2，UE1的天线端口p0和天线端口p2在梳齿1上会受到UE7和UE8的天线端口p0和天线端口p2的干扰，UE1的天线端口p1和天线端口p3在梳齿2上会受到UE5和UE6的天线端口p0和天线端口p2的干扰。可以进一步提高终端设备的天线端口占用的频域资源自由度，进一步提高对该终端设备造成的干扰随机度，从而进一步提高干扰随机化效果。
在一些实施例中，结合上述场景1，假设对于每个UE，循环移位参考值根据公式(2)获得天线端口pi的占用的梳齿的索引后，每个UE的每个天线端口占用的梳齿如表8和图8所示。
在发送时刻1，UE1的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。UE5的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。其他UE不一一列举，具体参照表8。以UE1为例，UE1的天线端口p0至天线端口p3在梳齿1上会受到UE5的天线端口p0至天线端口p3的干扰。
表8

在发送时刻2，UE1的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。UE5的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。其他UE不一一列举，具体参照表8。以UE1为例，UE1的天线端口p0至天线端口p3在梳齿1上会受到UE5的天线端口p0至天线端口p3的干扰。
类似地，在发送时刻n，UE1的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。UE5的天线端口p0、天线端口p1、天线端口p2和天线端口p3占用梳齿1。其他UE不一一列举，具体参照表8。以UE1为例，UE1的天线端口p0至天线端口p3在梳齿1上会受到UE5的天线端口p0至天线端口p3的干扰。
在任意发送时刻，每个天线端口都会受到相同天线端口的干扰，以UE1为例，在任意发送时刻，UE1的天线端口p0至天线端口p3都会受到UE5的天线端口p0至天线端口p3的干扰，这样并不利于干扰随机化。
在一种可能的设计方法中，第一偏移量是根据第一天线端口占用的循环移位值确定的。
可选地，第一偏移量与循环移位值可存在对应关系。
如此，根据第一偏移量获取天线端口占用的梳齿，第一偏移量的取值与循环移位值有关，从而天线端口占用的梳齿受循环移位值和第一偏移量影响，使得在不同的发送时刻，每个天线端口占用的梳齿和使用的循环移位值均会随机变化，则在不同的发送时刻对终端设备的天线端口造成干扰的天线端口也会随机变化。在相同发送时刻，对终端设备的不同天线端口造成干扰的天线端口不相同。可以实现码域和频域的二维干扰随机化，可以进一步增强干扰随机化效果，加快干扰随机化收敛速度。
此外，由于循环移位值的引入，即使同样是UEx的天线端口pa对UEy的天线端口pb产生的干扰，在不同的发送时刻，干扰水平仍可能会有很大差异。这样，可以保证极好的干扰随机化效果。
在一种可能的设计方法中，第一偏移量是根据第一天线端口占用的循环移位值确定的，可以包括：第一偏移量是根据循环移位值的所属范围确定的。
可选地，循环移位值的所属范围可以划分为至少两个区间。

一些实施例中，若天线端口pi对应的循环移位值αi mod 2π∈R0，则第一偏移量的取值为若αi mod 2π∈R1，则第一偏移量的取值为类似地，若αi mod 2π∈Ry-1，则第一偏移量的取值为
其中，R0表示第一范围，R1表示第二范围，类似地，Ry-1表示第y范围，数学符号∈表示属于。
可选地，也就是说，y个范围的并集为2π，任意两个范围的交集为空。
一些实施例中，循环移位值可以满足公式：
其中，MZC表示序列的长度，c()为伪随机序列，伪随机序列与小区标识有关。nf表示第一天线端口对应的系统帧号，表示每个系统帧包含的时隙数量；表示每个时隙包含的OFDM符号数量。表示子载波配置μ下，第一天线端口对应的时隙编号。l0+l′表示第一天线端口对应的OFDM符号编号，l0表示第一天线端口占用的时域资源包括的一个或多个OFDM符号中起始OFDM符号的索引，l′表示第一天线端口占用的时域资源包括的一个或多个OFDM符号中一个OFDM符号的相对索引。
另一些实施例中，循环移位值可以满足公式： 。其中，表示的含义可参照上述“第三，循环移位值”中对应的的阐述，此处不再赘述。
又一些实施例中，循环移位值可以满足公式：
需要说明的是，本申请实施例中无特殊说明的情况下，各公式之间的参数表示的含义可以相互参考，不予限制。

一些实施例中，第一偏移量是根据第一天线端口占用的循环移位值确定的,根据梳齿数量、梳齿偏移量和第一偏移量确定的天线端口pi的占用的梳齿的索引可以满足下述公式：或者，其中，表示梳齿偏移量，KTC表示梳齿数量，koffset表示第一偏移量。
例如，第一偏移量是根据循环移位值的所属范围确定的，根据梳齿数量、梳齿偏移量和第一偏移量确定的天线端口pi的占用的梳齿的索引可以满足下述公式(23)。
与上述公式(2)类似，上述公式(23)中，表示梳齿偏移量，KTC表示梳齿数量，koffset0至koffsetn-1均可表示第一偏移量。
在满足第一条件：且pi∈{1001,1003},且的情况下，天线端口pi的占用的梳齿的索引与循环移位值有关。例如，循环移位值αi mod 2π∈R0时，天线端口pi的占用的梳齿的索引满足例如，循环移位值αi mod 2π∈R1时，天线端口pi的占用的梳齿的索引满足 例如，循环移位值αi mod 2π∈Ry-1时，天线端口pi的占用的梳齿的索引满足
类似地，在满足第二条件：且pi∈{1001,1003},且 的情况下，天线端口pi的占用的梳齿的索引与循环移位值有关，具体参照上述公式，不详细赘述。在不满足第一条件，且不满足第二条件的情况下(如上述公式(23)所示，或者pi∈{1000,1002}或者 且天线端口pi的占用的梳齿的索引与循环移位值有关，例如，循环移位值αi mod 2π∈R0时，天线端口pi的占用的梳齿的索引满足 例如，循环移位值αi mod 2π∈R1时，天线端口pi的占用的梳齿的索引满足例如，循环移位值αi mod 2π∈Ry-1时，天线端口pi的占用的梳齿的索引满足
下面结合表9和图9对第一偏移量是根据第一天线端口占用的循环移位值确定的，至少根据第一偏移量确定天线端口占用的梳齿后每个终端设备占用的梳齿进行阐述。
以上述场景1为例，第一偏移量是根据第一天线端口占用的循环移位值确定的，至少根据第一偏移量确定UE1至UE8的每一个天线端口(天线端口p0至天线端口p3)占用的梳齿，假设上述公式(23)中，c＝0,1,2,3，y＝4，则每个SRS端口pi占用的梳齿的索引可表示为：
，每个UE占用的梳齿可以如表9和图9所示。
结合表9和图9，在发送时刻1，UE1的天线端口p0至天线端口p3分别占用梳齿1、梳齿2、梳齿3和梳齿4。UE2的天线端口p0至天线端口p3分别占用梳齿2、梳齿3、梳齿4和梳齿1。不一一列举，具体参照表9和图9。
以UE1为例，在发送时刻1，UE1的天线端口p0会在梳齿1上受到UE2的天线端口p3、UE3的天线端口p2、UE4的天线端口p1、UE5的天线端口p0、UE6的天线端口p3、UE7的天线端口p3、和UE8的天线端口p1的干扰。UE1的天线端口p1会在梳齿2上受到UE2的天线端口p0、UE3的天线端口p3、UE4的天线端口p2、UE5的天线端口p1、UE6的天线端口p0、UE7的天线端口p2、和UE8的天线端口p2的干扰，不一一列举，具体参照表9和图9。
在发送时刻2，UE1的天线端口p0至天线端口p3分别占用梳齿2、梳齿3、梳齿4和梳齿1。UE2的天线端口p0至天线端口p3分别占用梳齿3、梳齿4、梳齿1和梳齿2。不一一列举，具体参照表9和图9。
以UE1为例，在发送时刻2，UE1的天线端口p0会在梳齿1上受到UE2的天线端口p3、UE3的天线端口p2、UE4的天线端口p1、UE5的天线端口p3、UE6的天线端口p2、UE7的天线端口p1、和UE8的天线端口p0的干扰，不一一列举，具体参照表9和图9。
可见，在不同的发送时刻，每个UE的每个天线端口占用的梳齿均会发生变化，对同一个天线端口产生干扰的天线端口会随机变化，例如在上述发送时刻1和发送时刻2对UE1的天线端口p0造成干扰的天线端口不同。在相同发送时刻，对UE的不同天线端口造成干扰的天线端口不相同，例如在发送时刻1对UE1的天线端口p0造成干扰的天线端口和对UE1的天线端口p1造成干扰的天线端口不同，可以进一步增强干扰随机化效果。
此外，由于循环移位值的引入，即使同样是UEx的天线端口pa对UEy的天线端口pb产生的干扰，在不同的发送时刻干扰水平仍可能会有很大差异。这样，可以保证极好的干扰随机化效果。
表9

图5所示的通信方法，通过采用第一偏移量确定终端设备的第一天线端口占用的梳齿，可以使不同发送时刻终端设备的天线端口占用的频域资源(梳齿)随机变化，从而使对该终端设备的天线端口造成干扰的终端设备的天线端口随机变化，实现了频域干扰随机化，能够达到更好的干扰随机化效果。
或者，引入循环移位值，根据第一偏移量获取第一天线端口占用的梳齿，第一偏移量的取值与循环移位值有关，从而第一天线端口占用的梳齿受循环移位值和第一偏移量影响。使得在不同的发送时刻，每个天线端口占用的梳齿和使用的循环移位值均会随机变化，则在不同的发送时刻对终端设备的天线端口造成干扰的天线端口也会随机变化。在相同发送时刻，对终端设备的不同天线端口造成干扰的天线端口不相同。如此，可以实现码域和频域的二维干扰随机化，可以进一步增强干扰随机化效果，加快干扰随机化收敛速度。
一些实施例中，部分探测偏移量满足上述公式(4)：
如果高层参数(例如kF和PF等)不发生变化，则部分探测带宽在跳频带宽中的相对位置仅由起始资源块跳变偏移量khop决定。而khop由参考信号对应的跳频周期的索引和协议预定义的表格(例如表3)决定，这使得每个天线端口占用的部分探测带宽具有很强的规律性，不利于干扰随机化。
结合表10和图10，场景2：小区1包括UE1和UE2，每个UE均包括2个天线端口(例如分别为天线端口p0和天线端口p1)，UE1和UE2的各个天线端口使用基序列r1 和各个天线端口对应的循环移位值生成参考信号，UE1和UE2的各个天线端口占用的梳齿和使用的循环移位值至少有一个不同。小区2包括UE3和UE4，每个UE均包括2个天线端口(例如分别为天线端口p0和天线端口p1)，UE3和UE4的各个天线端口使用基序列r2和各个天线端口对应的循环移位值生成参考信号，UE3和UE4的各个天线端口占用的梳齿和使用的循环移位值至少有一个不同。图10中每个格子表示一个RB，扫描带宽为16RB，跳频带宽为4RB，跳频周期为4。需要说明的是，表10和图10中未示出天线端口。
每个终端设备的各个天线端口对应的部分探测起始位置索引kF和频率缩放因子PF相同，具体如表10所示，有2个UE可以在相同的时频资源上发送参考信号。
表10
假设同一小区内UE的各个天线端口之间相互正交，如果高层参数(例如kF、和PF等)不发生变化，则在任意发送时刻一个UE的天线端口都会受到固定的干扰，例如UE1的天线端口都会受到UE3的天线端口的干扰。
示例性地，图11为本申请实施例提供的另一种通信方法的流程示意图。图11所示的方法可以与图5所示的方法结合使用，结合使用可以达到更好的干扰随机化效果，图11所示的方法可以与图5所示的方法也可以分别单独使用。
如图11所示，该通信方法包括如下步骤：

关于S1101的具体实现方式可参照上述S501，此处不再赘述。
S1102，终端设备根据配置信息，在M个天线端口上发送参考信号。相应地，根据配置信息，在M个天线端口上接收参考信号。
示例性地，M为大于0的整数。
可选地，终端设备可以包括M个天线端口。
在一种可能的设计方法中，M个天线端口中的每个天线端口占用的频域资源的起始位置至少是根据第四偏移量确定的。
例如，结合上述场景2，UE1的天线端口p0至天线端口p1中的每个天线端口占用的频域资源的起始位置可以至少是根据第四偏移量确定的。
可选地，第四偏移量可以为大于或等于0的整数。
在一些实施例中，第四偏移量可以至少是根据小区标识和参考信号对应的跳频周期的索引确定的。
例如，结合图10，参考信号对应的跳频周期的索引可以为：跳频周期1等。
一些实施例中，第四偏移量可以是第四随机数。
也就是说，第四偏移量可以为随机数，例如第四偏移量为大于0的随机数。
可选地，第四偏移量或第四随机数可以满足公式(24)、或公式(25)。

上述公式(24)、或公式(25)中，krand表示第四偏移量或第四随机数(krand可以表示第四偏移量；当第四偏移量为第四随机数时，krand可以表示第四随机数)，数学符号∑ 表示求和，c()为伪随机序列，伪随机序列与小区标识有关，表示参考信号对应的跳频周期的索引，数学符号表示向下取整，nSRS表示参考信号的计数值，数学符号∏表示累乘，数学符号mod表示取模。
可选地，
需要说明的是，上述公式(25)和中参数的含义可参照上述对公式(5)以及表3的阐述，此处不再赘述。
需要说明的是，上述公式(24)、或公式(25)中的m与序列长度M无关，上述公式(24)、或公式(25)中的以m的取0至7之间的整数为例进行阐述，本申请对上述公式(24)、或公式(25)中的m的取值范围不进行限定。
一些实施例中，M个天线端口中的每个天线端口占用的频域资源的起始位置至少是根据第四偏移量确定的，可以包括：M个天线端口中的每个天线端口占用的频域资源的起始位置可以是根据部分探测偏移量确定的。
可选地，部分探测偏移量可以是根据每个资源块包含的子载波数量、跳频带宽、部分探测起始位置索引、起始资源块跳变偏移量、频率缩放因子和第四偏移量确定的。
示例性地，部分探测偏移量可以满足下述公式(26)。
在公式(26)中，krand表示第四偏移量。
公式(26)中其他参数的含义与上述公式(4)类似，为每个资源块包含的子载波数量。表示跳频带宽，mSRS,BSRS为根据高层参数BSRS和CSRS及协议预定义表格(例如表3)确定的跳频带宽。kF为部分探测起始位置索引，kF∈{0,1,…,PF-1}。khop表示起始资源块跳变偏移量。PF表示频率缩放因子。
一些实施例中，天线端口pi的频域起始位置可满足下述公式(27)。
上述公式(27)中，满足其中，为每个资源块包含的子载波数量，例如为12。表示天线端口pi的占用的梳齿的索引。
上述公式(27)中，表示跳频偏移量。可选地，跳频偏移量可满足其中，为每个资源块包含的子载波数量。
上述公式(27)中，可表示部分探测偏移量，部分探测偏移量可以是根据每个资源块包含的子载波数量、跳频带宽、部分探测起始位置索引、起始资源块跳变偏移量、频率缩放因子和第四偏移量确定的，例如上述公式(26)。
结合图12，以上述场景2为例，至少根据第四偏移量确定UE1至UE4的每一个天线端口(天线端口p0至天线端口p1)占用的频域资源的起始位置，每个UE占用的频域资源的起始位置可以如图12所示。
在跳频周期1，UE1的天线端口和UE3的天线端口占用相同的频域资源的起始位置，UE2的天线端口和UE4的天线端口占用相同的频域资源的起始位置。在跳频周期2，UE1的天线端口和UE4的天线端口占用相同的频域资源的起始位置，UE2的天线端口和UE3的天线端口占用相同的频域资源的起始位置。类似地，在跳频周期n，UE1的天线端口和UE3的天线端口占用相同的频域资源的起始位置，UE2的天线端口和UE4的天线端口占用相同的频域资源的起始位置。
以UE1为例，在跳频周期1，对UE1的天线端口造成干扰是UE3的天线端口，在跳频周期2，对UE1的天线端口造成干扰是UE4的天线端口，可见，在不同的跳频周期对UE1的天线端口造成干扰的天线端口不同，这样会带来较好的干扰随机化效果，可以加快干扰随机化收敛速度，提升信道估计性能。
基于图11所示的通信方法，在确定天线端口占用的频域资源的起始位置时，引入第四偏移量，可以使在不同跳频周期每个天线端口占用的频域资源的起始位置随机变化，对某个终端设备的天线端口造成干扰的天线端口也就会随机变化，实现了频域干扰随机化，这样会带来较好的干扰随机化效果，可以加快干扰随机化收敛速度，提升信道估计性能。
