Description

信号处理的方法和装置 技术领域
本申请涉及通信系统，更具体地，涉及一种信号处理的方法和装置。
背景技术
在长期演进(long term evolution，LTE)系统中，物理上行共享信道(physical uplink shared channel，PUSCH)和PUCCH使用解调参考信号(demodulation reference signal，DMRS)进行信道估计，从而进行信号解调。在LTE系统中，上行DMRS的基序列可以直接映射到资源元上，不需要任何编码处理。在LTE中，上行DMRS参考序列被定义为基本序列的循环移位，上行DMRS的基序列由Zadoff-Chu序列(ZC序列)循环扩充获得。该ZC序列，是满足恒包络零自相关(constant amplitude zero auto-correlation，CAZAC)序列性质的序列。
在新无线电接入技术(new radio access technology，NR)中支持上行传输的信号采用离散傅里叶变换扩频的正交频分复用多址接入(discrete Fourier Transform spreadOFDM，DFT-s-OFDM)波形，上行传输的信号使用π/2BPSK调制方法，并且，经过DFT变换后的上行传输的信号可以进行频域的滤波操作。上行传输信号使用π/2BPSK调制时，可以使用基于Gold序列的序列，还可以使用计算机生成序列(computer generated sequence，CGS)。目前，拟在NR中支持DFT-s-OFDM,DMRS波形使用ZC序列；另拟在NR中支持采用π/2 BPSK调制的上行传输的信号的DMRS使用ZC序列。
但是，若上行DMRS使用ZC序列会导致DMRS的峰均功率比(peak-to-average power ratio，PAPR)比相应的上行传输信号的PAPR高，导致DMRS带外杂散发射和带内信号损失，影响信道估计性能，或者导致上行覆盖受限。另，在上行DFT-s-OFDM,DMRS波形使用π/2,BPSK调制方式，并使用滤波器时，若上行DFT-s-OFDM,DMRS波形使用基于Gold序列的序列或者CGS时，若不能进行合适的筛选，会导致序列的频率平坦度较差，从而不利于进行信道估计。若上行DFT-s-OFDM,DMRS波形使用ZC序列会导致DMRS的峰均功率比(peak-to-average power ratio，PAPR)比传输数据的PAPR高，导致导频信号带外杂散发射和带内信号损失，影响信道估计性能，或者导致上行覆盖受限。
也就是说，采用现有的DMRS序列，不能够满足目前的通信应用环境。另采用现有的用于PDSCH的参考信号(例如，DMRS)所使用的序列，不能够满足目前利用PUSCH发送信号的通信应用环境。

传统方案中，6长的DMRS序列用于支持频域带宽为包含12个子载波的PUSCH传输，其中，6长的DMRS序列映射在6个等间隔的子载波上，例如，映射在间隔为1个子载波占用的带宽。6长的DMRS序列为表1中的任意一组元素φ(0),…,φ(5)，该6长的DMRS序列s(n)变换为序列y(m)，y(n)＝[s(n)s(n)]，即：y(n)中的。
传统方案中，为了支持频域带宽为包含12个子载波的1RB的PUSCH传输，根据采用频域为梳齿(comb)-2结构对应的CGS序列确定DMRS序列，即将时域的基序列重复两次，然后针对重复的时域基序列分别采用OCC[+1，+1]和[+1,-1]，之后进行DFT变换。其中，为了保证低PAPR特性、较好的频域平坦度、较好的时域自相关特性、较低的序列互相关特性这多个因素，DMRS序列采用的调制方式通常为高阶调制方式，例如，采用8PSK的序列生成方式为：s(n)＝e jφ(n)п/8,0≤n≤5，其中，φ(n)可以根据表1确定。
表1

Figure PCTCN2020071476-appb-000046
Figure PCTCN2020071476-appb-000047
其中，DMRS在频域上的映射采用的comb-2的结构如图2所示，即对于某一个用户的PUSCH而言，DMRS仅占用奇数子载波或偶数子载波，对于系统而言，被同时调度的其他用户的PUSCH可以占用另一个子载波组。
将表1所示的序列进行[+1+1]重复以及[+1-1]重复，并变换到频域进行频域滤波最终输出每个子载波上的序列值如表2所示，上述变换流程如图3所示。例如，一个N/2长的基序列s N/2进行重复得到s (0)＝[s N/2,s N/2]和s (1)＝[s N/2,-s N/2]，再将s (0)和s (1)经过DFT变换，得到N长的序列s (0)＝DFT(s (0))只会占用图2所示的偶数子载波，s (1)＝DFT(s (1))只会占用图2所示的奇数子载波。
由下述表2和上述表1可知，6长的序列s可以通过搜索使得经过[+1+1]重复之后的序列的PAPR相对表1中的PAPR值较低，但是序列s经过[+1-1]重复之后，PAPR却高于表1中的PAPR值。也就是说，传统方案中，无法找到合适的序列，使得经过[+1+1]重复之后的PAPR值以及[+1-1]重复之后的PAPR值都相对PUSCH的PAPR值较低。

另一传统方案中，6长的DMRS序列用于生成频域带宽为包含12个子载波的PUSCH/PUCCH的DMRS，其中，6长的DMRS序列映射在6个等间隔的子载波上，例如，映射在间隔为1个子载波占用的带宽，即，每两个连续子载波上均有且仅有一个子载波承载DMRS。6长的DMRS序列根据表1a中的任意一组元素Φ(0),...,Φ(5)生成，生成方式为：Φ(0),...,Φ(5)经过8PSK调制之后，通过不同的重复方式映射到频域上的奇数编号的子载波和偶数编号子载波上，其中，假设DMRS占用的起始子载波的编号为0，则通过{Φ(0),...,Φ(5),Φ(0),...,Φ(5)}的重复方式后进行DFT变换可以将DMRS序列映射到偶数编号的子载波上，通过{Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}的重复方式后进行DFT变换可以将DMRS序列映射到奇数编号的子载波上。

其中，DMRS在频域上的映射采用的comb-2的结构如图2所示，即对于某一个用户上行传输的数据而言，DMRS仅占用奇数子载波或偶数子载波，对于系统而言，被同时调度的其他用户的上行传输的数据的DMRS可以占用另一个子载波组。
将表1a所示的序列经过调制后进行不同的重复方式，并通过DFT变换到频域进行频域滤波最终获得的序列的PAPR值如表2a所示，上述变换流程如图3所示。例如，一个经过序列调制的N/2长的基序列s N/2进行重复得到s (0)＝[s N/2,s N/2]和s (1)＝[s N/2,-s N/2]，再将s (0)和s (1)经过DFT变换，得到N长的序列s (0)＝DFT(s (0))只会占用图2所示的偶数子载波，s (1)＝DFT(s (1))只会占用图2所示的奇数子载波。
由下述表2a和上述表1a可知，6长的基序列s N/2经过{Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}重复之后，PAPR明显高于数据的PAPR值

图4示出了本申请实施例的信号处理的示意性流程图。
本申请实施例的发送端可以是终端，对应的接收端为网络设备，或者发送端为网络设备，接收端为终端。下述实施例以发送端为终端，接收端为网络设备为例进行说明，但本申请对此不进行限定。
401，终端确定第一频域资源，该第一频域资源包括子载波编号为k的K个子载波，其中，k＝u+L*n+delta，n＝0,1，...，K-1，L为大于等于2的整数，delta∈{0,1,…,L-1}，u为整数，该子载波编号是按照频率上从低到高或者从高到低的顺序编号的。
具体地，在n分别取0,1，…，K-1时，根据k＝u+L*n+delta得到的子载波可以形成一个梳齿结构。其中，k为子载波的编号，u可以是该K个子载波中的第一个子载波的子载波编号，L的取值可以由梳齿(comb)结构确定，例如，对于comb-2的结构(如图2所示)，L取2；对于comb-4的结构(如图5所示)，L取4。Delta可以是0,1,…,L-1，中的任意一个值，在delta的取值不同的情况下，得到的第一频域资源也不同，即不同的delta的取值对应于不同梳齿的子载波组合。例如，如图2所示，delta＝0时，第一频域资源可以包括梳齿1对应的子载波；delta＝1时，第一频域资源可以包括梳齿2对应的子载波。这里的分别取值指的是n取值为0,1，…，K-1的某个的情况时。
应理解，本申请实施例的频域资源以“子载波”为例进行说明，但是该频域资源还可以是载波或者其他频域单元，本申请对此不进行限定。
还应理解，该L的取值随着梳齿结构comb-L的不同，还可以取其他值，本申请对此不进行限定。
应理解，上述确定所述第一序列的步骤可以是可选的，也可以是其它步骤替代。一个实施例中，在其中，在生成所述参考信号之前，所述方法还包括：根据所述delta的取值，确定第一序列。具体可以是根据存储一个映射关系，该映射关系可以是被其它设备或装置配置后存储的，也可以是预定义的。该映射关系可以是一个delta与第一序列的映射关系，或者是生成公式中的一个参数。又一个实施例中，也可以直接根据delta的值生成第一序列，其中，所述第一序列和delta的值相关联。
又一个实施例中，在第一频域资源上发送所述参考信号，所述第一频域资源包括第一子载波集合，所述第一子载波集合的子载波之间有固定的载波间隔，例如前文所述的梳齿状的形式，例如，第一子载波集合中的子载波间隔为1个子载波。以6为例，第一子载波集合为{a0,a1,a2,a3,a4,a5}，若间隔为1个子载波，那么该子载波集合在频域上由小到大排列可以为{a0,b,a1,c,a2,d,a3,e,a4,f,a5,g}。其中，b,c,d,e,f,g为其它子载波。在确定第一频域资源时，根据第一子载波集合的偏移值，确定采用的第一序列。该偏移值可以是相对偏移值也可以是绝对偏移值。一个实施例中，若b,c,d,e,f,g为第二子载波集合，组成或部分组成第二资源，即b,c,d,e,f,g分别为{b0,b1,b2,b3,b4,b5}、那么该子载波集合在频域上由小到大排列为{a0,b0,a1,b1,a2,b2,a3,b3,a4,b4,a5,b5}。根据相对偏移值，由于该第一子载波集合和第二子载波集合的起始子载波的位置为a0,b0,因此可以配置a0生成第一序列，b0生成第二序列(类似第一序列，对b0来说也就是b0的第一序列)，即按照第一频域资源的起始位置的相对位置确定。由于上述两个子载波集合是梳齿状排列，也可以直接按照两个子载波集合的位置确定第一序列和第二序列。相对位置的确认方式可以是比较出来的，绝对位置的确认方式可以是计算出来的，例如直接根据预设的计算规则中的某个参数确定(类似于上实施例中的delta)，或者直接根据一个参数与第一序列的关联关系。例如在本实施例中， k＝u+L*n+delta，当delta＝0时，对应第一序列，当delta＝1时，对应第二序列。这样在发送参考信号时(或之前)，发送端就可以直接按照上述公式中的各个参考信号对应的资源确定出应该在何种位置采用何种第一序列生成参考信号。
又一个实施例中，可以是直接根据一个偏移值算出。对于上行数据传输来说，例如，当传输预编码不使能时：
传输序列r(m)可以先根据如下关系映射到中间值

本发明中的序列映射到频域资源的方式适用于上述configuration Type1。
可选的，所述中间值为一个信号，该信号会经过变换之后映射到k个子载波及l个OFDM符号组成的时频资源上。
其中，配置模式(configuration type)可以是通过高层信令配置的，例如DMRS-UplinkConfig，k′和Δ与都与

可选的，根据上述关联关系，本发明实施例根据上述
Figure PCTCN2020071476-appb-000070
和CDM组直接确定所述第一序列。
可选的，根据上述关联关系，本发明实施例根据所述第一信号的时频资源直接确定第一序列。
可选的，存在至少1个所述第一序列组，其特征在于，同一个序列长度，同一个第一序列组内，包括2个不同序列。
在一个实施例中，L＝2，K＝6，n＝0,1,2,3,4,5，delta＝0。
具体地，L＝2即该梳齿结构为comb-2。K＝6，即第一频域资源包括6个子载波。再结合n＝0,1,2,3,4,5、delta＝0、k＝u+L*n+delta，终端可以确定该第一频域包括处于奇数位置的子载波，即如图2中的梳齿1。此外，由K＝6，L＝2，还可以获知该第一频域资源可以包括一个RB中的12个子载波中的奇数位置的子载波。
在另一个实施例中，若L＝2，K＝6，n＝0,1,2,3,4,5，delta＝1，则该第一频域资源可以包括如图2中梳齿2所示的子载波。
402，终端根据delta的取值，确定第一序列，其中delta的取值不同对应的第一序列不同，第一序列的长度为K。
具体地，第一序列的长度为K，即第一序列包括K个元素。delta的取值不同可以对应不同的序列，例如，多个delta的取值可以与多个序列具有一一对应的映射关系，这样终端可以根据该映射关系，确定出delta的某个取值对应的序列。需要说明的是，该映射关系可以以列表的形式表示。
可选地，该第一序列不是BPSK调制的序列且不是pi/2 BPSK调制的序列。
可选地，该第一序列是8PSK、16PSK或32PSK中的任一项调制的序列。
具体地，不同调制方式对应的序列数目不同，8PSK、16PSK或32PSK中的任一项调制对应的序列数目大于调制方式为pi/2 BPSK对应的序列数目，这样有助于为不同梳齿的频域资源选择相关性较低的序列，从而提高采用不通过梳齿的频域资源进行通信的效率。
在一个实施例中，终端根据该delta的取值可以确定第一序列组。
具体地，delta的取值不同对应的频域资源可以是不同子载波组合，例如，如图2所示，delta＝0，则第一频域资源包括梳齿1所示的子载波；delta＝1，则第一频域资源包括梳齿2所示的子载波。多个delta的取值与多个序列组具有映射关系，这样终端可以根据该映射关系，确定某一个delta的取值(例如，第一delta)确定第一序列组。
不同调制方式对应的序列数目不同，8PSK、16PSK或32PSK中的任一项调制对应的序列数目大于调制方式为pi/2 BPSK对应的序列数目，这样有助于为不同梳齿的频域资源上承载的DMRS序列的PAPR较低，从而避免带外杂散发射和带内信号损失，或者提高上行覆盖；同时，还可以保证不同梳齿的频域资源上承载的DMRS序列的自相关性、频域平坦度等特性均较低，从而提高基于该DMRS的信道估计性能。
在一个实施例中，终端根据该delta的取值和小区标识或序列组标识可以确定第一 序列。
具体地，delta的取值不同对应的频域资源可以是不同子载波组合，例如，如图2所示，delta＝0，则第一频域资源包括梳齿1所示的子载波；delta＝1，则第一频域资源包括梳齿2所示的子载波。多个delta的取值与多个序列集合具有映射关系，该映射关系可以是预先定义的，这样终端可以根据该映射关系和当前传输时刻的delta的取值(例如，第一delta)确定从多个序列集合中确定一个序列集合，该序列集合与第一delta相对应。终端可以根据小区标识或序列组标识确定序列集合中的一个序列，作为生成DMRS的序列。
可选地，终端可以根据小区标识或序列组标识确定第一序列组。
具体地，终端和网络设备均预存多个序列组，其中，每一个序列组均对应一个小区标识或者序列组标识。终端根据网络设备的配置信息，该配置信息中包括小区标识或者序列组标识，便可以确定传输DMRS采用的序列组。从而，不同的小区可以采用不同的序列组，降低了小区间的信号干扰。进一步的，多个delta的取值与序列组中的多个序列具有预先定义的映射关系，终端根据delta取值从该序列组中确定一个序列，作为生成DMRS的序列。
可选地，终端可以根据小区标识或序列组标识确定该第一序列组。
具体地，终端可以将具有相同小区标识的序列划分到一个序列组中，也就是说，不同的序列组分别为不同的小区服务。终端也可以与网络设备约定序列组标识，不同序列组标识对应不同的序列组，这样终端可以根据网络设备配置的序列组标识，确定对应的序列组。即终端可以从合适的该序列组中选择序列生成参考信号，进而能够准确的解调第一信号，提高了数据传输的质量。
可选地，终端接收指示信息，该指示信息用于指示至少两个序列组中的每个序列组中的用于生成参考信号的序列。相应地，网络设备发送该指示信息。
具体地，网络设备可以向终端发送指示信息，通过该指示信息指示至少两个序列组中的每个序列组中的序列，即更进一步通知终端采用序列组中的哪一个序列，这样终端根据该指示信息指示的序列生成参考信号，相对于为从每个序列组中选择序列配置指示信息，本申请实施例能够节省信令开销。应理解，步骤401和步骤402是可选的两个步骤
403，终端根据该第一序列，生成第一信号的参考信号，该第一信号为pi/2 BPSK调制的信号。
具体地，终端可以将第一序列的K个元素分别映射到第一频域资源上的K个子载波上得到该参考信号。
需说明的是，映射到不同delta的取值对应的频域资源上的参考信号可以是同一个终端不同参考信号，也可以是不同终端的参考信号，本申请对此不进行限定。
应理解，第一信号可以是pi/2 BPSK调制的数据或信令，本申请对此不进行限定。
还应理解，参考信号可以是解调参考信号(demodulation reference signal，DMRS)、UCI、SRS以及PTRS，或者还可以为确认应答(acknowledgment，ACK)信息，或否定确认应答(negative,acknowledgment，NACK)信息，或者上行调度请求(scheduling,request，SR)信息，本申请对此不进行限定。
可选地，在delta＝0的情况下，所述生成第一信号的参考信号包括：
对序列{z(t)}中的元素经过离散傅里叶变换得到序列{f(t)}，t＝0,…,L*K-1，其中，当t＝0,1,…,L*K-1时，z(t)＝x(t mod K)，x(t)表示所述第一序列；
将所述序列{f(t)}中编号为L*p+delta的元素分别映射至所述子载波编号为 u+L*p+delta的子载波生成所述参考信号，所述p＝0,…,K-1。

具体地，终端和网络设备可以预先约定不同调制方式对应的序列组合，例如，从16PSK调制的多个序列中选择30序列，该30个序列可以是生成的参考信号的性能较高的序列，终端再从该序列组合中选择第一序列来生成参考信号，从而提高了终端和网络设备之间的通信效率。相应地，终端或网络设备也可以从8PSK调制的多个序列中选择30个序列，还可以从32PSK调制的多个序列中选择30个序列。这里可以继续介绍下上述两个公式得到的xn的原理。这样针对comb-2结构，终端可以根据预设条件和序列{s(n)}确定出用于生成在comb-2中梳齿1上传输的参考信号的第一序列。

可选地，A可以为调制符号，可以承载在序列所包含的K个元素上，A不随着n的变化而改变。
可选的，A为常数。例如A＝1。例如，A可以是终端设备和网络设备都已知的符号。A也可以表示是幅度。
需要说明的是，A是在一个发射时间单元上是常数不代表A是固定不变的，在不同的时刻发送第一信号时，A可以是变的。例如，序列{x(n)}中包含的全部N个元素是参考信号，A是参考信号的幅度，终端设备在第一次发送信号时，可以按A＝1发送。终端设备在第二次发送信号时，可以按A＝2发送。
可选地，第一序列生成参考信号具体可以是对第一序列进行重复，并进行DFT变换生成该参考信号。
具体地，针对comb-2结构，终端对第一序列进行重复可以是对第一序列进行[+1+1]重复，也可以是进行[+1-1]重复。对第一序列进行[+1+1]重复并进行DFT变换之后，可以将该2K个序列中的奇数序列(可以表示为2p+delta，p＝0,…,L-1)映射到comb-2的梳齿1上生成参考信号。对第一序列进行[+1-1]重复并进行DFT变换之后，可以将该2K个序列中的偶数序列映射到comb-2的梳齿2上生成参考信号。

又一个实施例中，针对comb-4结构，终端对第一序列进行重复可以是第一序列进行{Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5)}重复、{Φ(0),...,Φ(5),j×Φ(0),...,j×Φ(5),-Φ(0),...,-Φ(5),-j×Φ(0),...,-j×Φ(5)}重复、{Φ(0),...,Φ(5),-Φ(0),...,-Φ(5),Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}重复、或{Φ(0),...,Φ(5),-j×Φ(0),...,-j×Φ(5),-Φ(0),...,-Φ(5),j×Φ(0),...,j×Φ(5)}重复。对第一序列进行{Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5),Φ(0),...,Φ(5)}重复并进行DFT变换之后，可以将该4K序列中的编号为4p+delta(delta＝0)的序列映射到图5所示的梳齿1上生成参考信号。对第一序列进行{Φ(0),...,Φ(5),j×Φ(0),...,j×Φ(5),-Φ(0),...,-Φ(5),-j×Φ(0),...,-j×Φ(5)}重复并进行DFT变换之后，可以将该4K序列中的编号为4p+delta(delta＝1)的序列映射到图5所示的梳齿2上生成参考信号。对第一序列进行{Φ(0),...,Φ(5),-Φ(0),...,-Φ(5),Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}重复并进行DFT变换之后，可以将该4K序列中的编号为4p+delta(delta＝2)的序列映射到图5所示的梳齿3上生成参考信号。对第一序列进行{Φ(0),...,Φ(5),-j×Φ(0),...,-j×Φ(5),-Φ(0),...,-Φ(5),j×Φ(0),...,j×Φ(5)}重复并进行DFT变换之后，可以将该4K序列中的编号为4p+delta(delta＝3)的序列映射到图5所示的梳齿4上生成参考信号。
需要说明的是，在K＝6的情况下，即第一序列为6长的序列，第一频域资源为包括6个子载波，则comb-4结构需要占用4K＝24个子载波(即2个RB)，以满足从comb-4结构中选择6个满足需求的子载波；comb2结构需要占用2K＝12个子载波(即2个RB)，以满足从comb-2结构中选择满足需求的子载波。
可选地，在L＝2，K＝6，n＝0,1,2,3,4,5，delta＝0的情况下，所述生成第一信号的参考信号包括：对序列{z(t)}中的元素经过离散傅里叶变换得到序列{f(t)}，t＝0,…,2K-1，其中，序列{z(a)}＝所述序列{x(n)}，a＝0,…K-1，序列{z(b)}＝所述序列{x(n)}，b＝K,…2K-1，x(n)表示所述第一序列；将所述序列{f(t)}中编号为2p+delta的元素分别映射至所述子载波编号为k的K个子载波生成所述参考信号，所述p＝0,…,L-1。
具体地，序列{z(t)}可以是对第一序列{x(n)}进行[+1+1]重复得到的，即在t＝a的情况下，{z(a)}＝所述序列{x(n)}，a＝0,…K-1，在t＝b的情况下，序列{z(b)}＝所述序列{x(n)}，b＝K,…2K-1。终端再将序列{z(t)}中的元素经过离散傅里叶变换(discrete fourier transform，DFT)可以得到序列{f(t)}，并且将序列{f(t)}中k个编号为2p+delta(delta＝0)的元素映射到第一频域资源上的K个子载波上生成参考信号。本申请实施例能够将时域序列{z(t)}转变为频域序列映射到对应的子载波上。
例如，将序列{f(t)}中的K个元素分别映射至等间隔的的K个子载波上。如图6所示，该N个子载波之间的间隔为1，K个子载波在频域上是等间隔分布的。序列{f(t)}中的元素f(0)到f(K-1)映射的子载波的间隔为1个子载波。具体为：分别映射到K个等间隔的子载波，子载波编号为s+0,s+2,…,s+2(K-1)，s表示序列{f(t)}映射的K个子载波中的第一个子载波在通信系统中的子载波中的索引。

可选地，步骤403具体可以是对第一序列进行DFT变换，再进行滤波之后，映射到第一频域资源上得到该参考信号。例如，如图8所示，对第一序列{x(n)}进行DFT变换之后，再进行滤波得到{f(t)}。
可选地，终端设备对序列{x n}中的N个元素进行DFT处理，得到序列{f n}。这里主要指终端设备使用配置的序列{x n}中的N个元素进行DFT处理，得到频域序列，这里的频域序列指序列{f n}。然后，终端设备将序列{f n}映射至N个子载波上，生成第一信号并发送给网络设备。
可选的，终端设备对包含N个元素的序列{x n}进行DFT处理得到频域序列，然后，将频域序列分别映射至N个子载波上，生成第一信号并发送给网络设备的具体过程包括：
终端设备对包含N个元素的序列{x n}进行DFT处理，得到序列{f n}。
结合上面的描述或作为单独的一个实施例，参见图18。S301的执行，终端设备对序列进行DFT处理得到序列{f n}的过程中，可以不使用滤波器。可选的，终端设备对序列{x n}进行DFT处理得到序列{f n}的过程中，可以在使用滤波器之后，再进行DFT处理。可选的，终端设备对序列{x n}进行DFT处理得到序列{f n}的过程中，可以在进行DFT处理之后，再使用滤波器得到序列。
S302，终端设备将该序列分别映射至N个子载波上，得到N点的频域信号。
在具体实现中，N点的频域信号即包含N个元素的频域信号。
在下述本申请实施例中，s表示序列{f n}映射的N个子载波中的第一个子载波在通信系统中的子载波中的索引。
可选的，终端设备将序列{f n}中的N个元素分别映射至连续的N个子载波上。可选的，序列{f n}中的元素f 0到f N-1分别映射到N个连续的子载波，子载波标号为s+0,s+1,…,s+N-1。
在一种可能的示例中，终端设备将序列{f n}中的N个元素按照子载波从高到低的顺序，依次映射到N个子载波上。其中，一个序列{f n}中元素映射到一个频域子载波。频域子载波是频域资源的最小单元，其用于承载数据信息。
在一种可能的示例中，终端设备将序列{f n}中的N个元素按照子载波从低到高的顺序，依次映射到N个子载波上。将序列{f n}中一个元素映射到一个子载波就是在这个子载波上承载这个元素。映射之后，在该终端设备将数据通过射频发送时，相当于在这个子载波上发送这个元素。在通信系统中，不同的终端设备可以占用不同的子载波发送数据。N个子载波在通信系统中所存在的多个子载波中的位置可以是预定义或者网络设备通过信令配置的。
可选地，也可以将序列中的N个元素分别映射至等间隔的的N个子载波上。可选的，N个子载波之间的间隔为1，N个子载波在频域上是等间隔分布的。序列{f n}中的元素f 0到f N-1映射的子载波的间隔为1个子载波。具体为：分别映射到N个等间隔的子载波，子载波编号为s+0,s+2,…,s+2(N-1)
本申请实施例对于将序列{f n}中的N个元素分别映射至N个子载波上的方式，并不仅限于以上方式。
S303，终端设备对包含N个元素的频域信号进行快速傅立叶反变换(inverse,fast,Fourier,transformation，IFFT)，得到对应的时域信号，并为该时域信号添加循环前缀，生成第一信号。
S304，终端设备通过射频发送该第一信号。
可选的，在执行S303时，终端设备将生成的N点的频域信号通过IFFT后得到的时域信号是一个正交频分复用(orthogonal,frequency,division,multiplexing，OFDM)符号。在执行S303时，终端设备将第一信号通过射频发出去。也就是说，该终端设备在该N个子载波上发送承载序列{f n}的第一信号。
可选的，该终端设备可以在一个OFDM符号上发送承载序列{f n}的第一信号。也可以在在多个OFDM符号上发送承载序列{f n}的第一信号。
需要说明的是，在本申请实施例中，针对生成第一信号的方式并不仅限于上述终端设备对包含N个元素的序列{x(n)}进行DFT处理得到频域序列，然后，将频域序列分别映射至N个子载波上，生成第一信号并发送给网络设备的实现方式。
可选的，该可以对所述序列{x(n)}使用成型滤波器得到序列{y n}，然后，将序列{y n}调制到载波上，生成第一信号并发送给网络设备。
应理解，步骤403中对第一序列进行DFT变换之后，可以不进行滤波，之间映射到第一频域资源上得到该参考信号。如图9所示，对第一序列{x(n)}进行DFT变换之后得到{f(t)}。
需要说明的是，将序列中的元素映射到一个子载波上可以理解为在子载波上承载这个元素。映射之后，终端可以通过射频进行发送。
404，网络设备生成本地序列，该本地序列可以是第一序列或者第一序列的共轭转置。
具体地，网络设备也可以预先存储第一序列和频域资源的映射关系，或者协议中约定该映射关系，这样网络设备可以不同频域资源各自对应的第一序列。或者，网络设备在确定仅在梳齿结构的某一部分频域资源上接收参考信号，则网络设备可以仅生成该部分频域资源对应的第一序列。
例如，终端在入网后，可以使用配置的序列{x(n)}发送PUSCH或DMRS，而网络设备使用配置给终端设备的序列{x(n)}接收PUSCH或DMRS。
405，终端在该第一频域资源上发送该参考信号。相应地，网络设备在该第一频域资源上接收该参考信号。
具体地，在梳齿结构的频域资源中，不同梳齿的频域资源上映射的参考信号可以由不同的序列生成。也就是说，不同频域资源上的参考信号都可以根据需求选择不同的序列生成，从而提高了梳齿结构整体的频域资源上传输的参考信号的性能。例如，该性能可以是峰均功率比(peak to average power ratio，PAPR)较低，相关性较低，频域平坦度较好和时域自相关性较好中的至少一项。
需要说明的是，终端在该第一频域资源上还可以发送第一信号，该第一频域资源可以是与发送参考信号的频域资源相同，但是时域资源不同，本申请对此不进行限定。
406，网络设备根据该本地序列，处理该第一信号。
具体地，终端设备根据接收参考信号的第一频域资源，确定对应的本地序列，并根据该本地序列和该参考信号确定信道质量信息，进而根据该信道质量信息处理该第一信号。在本地序列为第一序列的情况下，网络设备可以根据参考信号与第一序列的比值确定信道质量信息；在本地序列为第一序列的共轭的情况下，网络设备可以根据参考信号与该第一序列的共轭的乘积，确定信道质量信息。

上述过程支持了频分正交的多个DMRS端口，比如，comb-2中，支持两个正交的DMRS端口占用不同的子载波，comb-4中，支持四个正交的DMRS端口占用不同的子载波。为了支持更多用户的，需要在相同的频域资源上通过码分复用支持更多的DMRS正交端口。
具体地，DMRS端口0采用的序列表示为{Φ(0),...,Φ(5),Φ(0),...,Φ(5)}，该DMRS端口0采用的序列会经过DFT变换，可选的进行滤波操作之后进行IDFT变换形成DMRS端口0，该DMRS端口0占用频域梳齿1，则正交方式一为：占用频域梳齿2的DMRS端口2可以采用{Φ(0),...,Φ(5),-Φ(0),...,-Φ(5)}序列，该序列会经过DFT变换，可选的进行滤波操作之后进行IDFT变换形成DMRS端口2；
正交方式二为：占用频域梳齿2的DMRS端口2还可以采用{Φ(0),...,Φ(5)}序列，该序列会经过DFT变换，之后与向量[0 1]进行张量积运算(Kronnecker)形成12长序列，比如，{β(0),...,β(5)}为{Φ(0),...,Φ(5)}经过DFT变换之后的序列，则，Kronnecker操作是

正交方式四为：将DMRS端口0采用的序列进行循环移位(cyclic shift，CS)操作，一种循环移位方式是向左移位序列长度1/4之后形成DMRS端口1的序列，例如，DMRS端口1为{Φ(3),Φ(4),Φ(5),Φ(0),...,Φ(5),Φ(0),Φ(1),Φ(2)}，该DMRS端口1采用的序列会经过DFT变换，可选的进行滤波操作之后进行IDFT变换形成DMRS端口1，该DMRS端口1占用频域梳齿1；
