Description

传输方法和传输装置
本申请要求于2018年9月15日提交中国专利局、申请号为201710854113.1、申请名称为“传输方法和传输装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种传输方法和传输装置。
背景技术
在3GPP正在进行的5G的标准化过程中，考虑系统支持更大的载波带宽。以系统最大支持到400MHz的载波带宽来讲，对于终端设备侧，由于受制于各种不同类型终端设备的成本，不是所有的终端设备都能够支持400MHz的带宽。因此，不同类型的终端设备可能需要接入到这400MHz带宽中的不同部分中去。为了支持较窄带宽的终端设备的接入，网络设备需要在400MHz的宽带载波上的不同位置放置至少一个同步信号或数据，以占用载波上的不同的带宽部分或频率位置，以便于更小带宽的终端设备从400MHz带宽的不同频域位置接入系统。
基于上述思路，当前技术中，网络设备将数据(例如，系统消息)和同步信号分别映射到当前载波上的特定的频域位置上，然后进行一个较大点数的N点IFFT操作，然后将经过N点IFFT操作之后得到信号的做上变频处理，最后将经过上变频处理后的到的信号通过射频(radio frequency，RF)和天线端口传输。
然而，上述方案中，如果同步信号或是数据不在400MHz带宽的中心频率，则终端设备检测到的同步信号或数据会产生一个频率偏差值，这个频率偏差值会对接收机引入额外的相位差和子载波偏移。而对于终端设备，其并不知道这个额外的相位差和子载波偏移的大小，从而导致终端设备不能正确地接收数据。

还应理解，在本申请的各种实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global  System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(New Radio，NR)等。
本申请实施例中的终端设备可以指用户设备(User Equipment，UE)、接入终端设备、用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动设备、用户终端设备、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1为适用于本申请实施例的系统100的示意图。如图1所示，该系统100包括网络设备101，该系统100还包括位于网络设备101覆盖范围之内的终端设备102以及终端设备103。网络设备101可以与终端设备102和终端设备103进行通信。应理解，图1中仅以网络设备101覆盖范围内的两个终端设备作为示例。显然，网络设备101的覆盖范围内也可以有更多的终端设备。
图1所示的系统可以支持大于20MHz的载波带宽。以系统最大支持到400MHz的载波带宽为例，由于终端设备102和终端设备103不能够支持400MHz的带宽，因此，终端设备102和终端设备103可能需要接入到这400MHz带宽中的不同部分中去。为了支持较窄带宽的终端设备102和终端设备103的接入，网络设备101需要在400MHz的宽带载波上的不同位置放置多个同步信号或数据，以占用载波上的不同的带宽部分或频率位置，以便于终端设备102和终端设备103从400MHz带宽的不同频域位置接入系统100。
因此，如图2所示，网络设备将数据(例如，系统消息)和同步信号分别进行子载波映射，将数据和同步信号映射到当前载波上的特定的频域位置上，然后进行一个较大点数的N点IDFT或IFFT操作，然后将经过N点IDFT或IFFT操作之后得到信号的做上变频处理，最后将经过上变频处理后的到的信号通过RF和天线端口传输。
当网络设备的发射机按照图2所示的方式进行信号的传输时，终端设备在初始接入时 候会按信号所在的预定义的频率栅格来逐步扫描同步信号或数据。
网络设备的发射机发送出的连续时域信号的表达式是：
Figure PCTCN2018105400-appb-000001
其中，N为多载波系统中当前载波上总的子载波个数，k表示第k个子载波，f SCS为所有子载波的子载波间隔，t表示时间，f C表示待传输的信号传输时的中心频率。a(k)表示子载波k上待传输的数据，可以是同步信号、广播消息或用户的业务数据(以下，简称为“数据”)。
Figure PCTCN2018105400-appb-000002
表示的归一化操作，这个是可选的。亦即公式(1)也可以表示为：
Figure PCTCN2018105400-appb-000003
本申请中所有的时域信号，或者做IDFT或IFFT之后的信号可以是进行对应长度的归一化操作，也可以不进行。以下为了描述的方便，都以做归一化操作为例进行描述。
终端设备的接收机在接收时，按照同步信号的频率对进入接收机的发射信号s(t)进行检测接收，有：
Figure PCTCN2018105400-appb-000004
其中，
Figure PCTCN2018105400-appb-000005
表示第i个同步信号的接收信号，f sync表示接收机检测同步信号SSBi时的频率，ferr表示接收机在检测同步信号时额外引入的频率偏差值，Δf＝f C-f sync。当接收的信号是用户的数据时，上式(3)的表达式是一样的，只是a(k)此时表示的是用户的数据而不是同步信号。下面以对同步信号的处理为例来做进一步的说明。
类似地，不进行归一化操作后的信号表达式为：
Figure PCTCN2018105400-appb-000006
假设终端设备检测同步信号的采样率为F SS，则终端设备对检测到的信号低通滤波，检测到M个SSB所在的子载波上的同步信号，其时域信号表达式为：
Figure PCTCN2018105400-appb-000007
其中：
Figure PCTCN2018105400-appb-000008
公式(6)的物理意义在于：在一个大带宽中，比如400MHz带宽中，如果同步信号不在400MHz带宽的中心频率的中心频率，则终端设备检测到的同步信号或数据会产生一个频率偏差值，这个频率偏差值会对接收机引入额外的相位差和子载波偏移。而对于做初始接入的终端设备，其并不知道这个额外的相位差和子载波偏移的大小，从而导致终端设备不能正确地接收数据。
需要说明的是，上述所述的接入也可以是设备对设备(Device to Device，D2D)场景下终端设备的接入。也就是说，本申请也同样适用于D2D场景。
基于此，本申请提供了一种传输方法，该方法通过对不在当前载波的中心频率处的同 步信号或数据进行相位补偿，能够尽可能抵消由于同步信号或数据不在当前载波的中心频率处而带来的相位差，进而能够尽可能的消除由相位差所带来的子载波偏移，从而能够提高终端设备解调数据的可能性。
在描述本申请实施例的传输方法之前，首先对本申请所涉及的一些概念或数据进行介绍。
(1)带宽部分(Band Width Part，BWP)
由于NR中，同一小区中不同终端设备的发射或者接收能力可能是不同的，系统可以为每个终端设备配置相应的带宽，这一部分配置给终端设备的带宽称为BWP，终端设备在自己的BWP上传输。例如，终端设备在自己的BWP上传输探测参考信号(Sounding Reference Signal，SRS)，以便网络设备进行信道估计和资源调度，并基于网络设备的调度，在自己的BWP上传输数据。系统针对不同的终端设备可以配置不同的BWP。为了支持不同的业务，不同的BWP可能会支持不同的传输带宽(即，BWP包含的资源块(Resource Block，RB)数不同)，子载波间隔、循环前缀(Cyclic Prefix，CP)等，调度单位可以是时隙或者微时隙等。
(2)同步信号
本申请所涉及的同步信号可以包括主同步信号(Primary Synchronization Signal，PSS)和/或辅同步信号(Secondary Synchronization Signal，SSS)。
可选地，所述同步信号可以承载在同步信号块(Synchronization Signal Block，SSB)上，通过SSB发送，但本申请实施例对此不作限定。
举例来说，一个SSB可以包括一个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号的PSS、一个OFDM符号的SSS和两个OFDM符号的物理广播信道(Physical Broadcast Channel，PBCH)。每个SSB中的PSS、SSS和PBCH占用连续的四个OFDM符号。
(3)系统消息
系统消息可以是保留系统消息(Remaining System Information，RMSI)和/或其他系统消息(Other System Information，OSI)，但本申请实施例并不限定于此。
以下，结合图3对本申请实施例的传输方法进行详细说明。
图3是根据本申请实施例的传输方法的一例的示意性交互图。应理解，图3示出了方法300的详细的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或仅执行图3中部分操作。
该方法300可以由发送端执行，发送端可以是网络设备，也可以是终端设备。其中，网络设备可以对应上述通信场景中的网络设备101，终端设备可以对应上述通信场景中的终端设备102或终端设备103。若发送端为网络设备，接收端可以是终端设备，也可以是另一网络设备。若发送端为终端设备，接收端可以是另一终端设备，本申请实施例并不限定于此。
如图3所示，该方法300主要包括S310和S320。以下，以发送端为网络设备，接收端为终端设备为例，描述本申请实施例。
S310，对k路信号中的m路第一信号进行对应频率值的相位补偿操作，得到m路第二信号。
其中，m路第一信号中的第i路第一信号位于当前载波的非中心频率处，例如位于400MHz系统带宽的最开始的100MHz带宽上。m路第一信号与m路第二信号一一对应，即，对m路第一信号中的每一路第一信号进行对应频率值的相位补偿操作，均生成一路第二信号。例如，即对m路第一信号中的第i路第一信号进行对应频率值的相位补偿操作，生成m路第二信号中的第i路第二信号。k≥1，m≥1，m≤k，且k和m均为整数，i遍历[1，m]中的整数。
以下，为了便于理解和描述，将m路第一信号中的第i路第一信号记作Y i(k)(为表述简单以下描述皆记为Y i)，将m路第二信号中的第i路第二信号记作Z i(k)(为表述简单以下描述皆记为Z i)。
对Y i进行对应频率值的相位补偿操作，即，将Y i与
Figure PCTCN2018105400-appb-000009
或
Figure PCTCN2018105400-appb-000010
进行相乘，得到的Z i，即
Figure PCTCN2018105400-appb-000011
或
Figure PCTCN2018105400-appb-000012
其中，Δf i为Y i的对应频率值。k表示k个子载波。
可选地，Δf i为第i路第一信号(即，Y i)的中心频率与所述当前载波的中心频率之间的差值。或者，Δf i为Y i的中心频率与所述当前载波内的数据信道的中心频率之间的差值。
应理解，在本申请中涉及的对某一信号进行的所述频率补偿操作，可以参照表达式(7)对该信号进行频率值Δf i的复数乘法，也可以参照表达式(7)对该信号进行频率值-Δf i的复数乘法，本申请实施例对此不作限定。便于描述的方便和理解，以下只使用表达式(7)的方式来进行描述，但这不等于排除了表达式(8)的方式来进行频率补偿。
可选地，所述m路第一信号中至少两路第一信号的子载波间隔不同。
下面，对Y i进行详细描述。
Y i可以是第i路同步信号(即，情况一)，或者，Y i可以是第i路数据(即，情况二)。或者，Y i可以是根据对第i路同步信号的第一操作处理生成的信号(即，情况三)，或者，Y i可以是根据对第i路数据的第一操作处理生成的信号(即，情况四)。
以下，不失一般性地，以m＝2，即i＝1，2为例，对本申请实施例进行详细描述。同时，为了便于理解和描述，将第一路第一信号和第二路第一信号分别记作：X 1和X 2。
情况一
即，Y i为第i路同步信号，Y 1＝X 1，Y 2＝X 2。
在此情况下，网络设备直接对Y i进行对应频率值的相位补偿操作，得到上述公式(7)或(8)所示的Z i。
可选地，Y i为带宽部分BWP。
进一步地，m路同步信号中的至少两路同步信号位于不同的带宽部分，或者，m路同步信号位于同一带宽部分。
情况二
即，Y i为第i路数据，Y 1＝X 1，Y 2＝X 2。
在此情况下，同情况一类似，网络设备直接对Y i进行相位补偿操作，得到上述的公 式(7)或(8)所示的Z i。
情况三
即，Y i是根据对第i路同步信号的第一操作处理生成的信号。
在此情况下，网络设备首先对X 1和X 2分别进行第一操作处理，得到Y 1和Y 2，然后再分别对Y 1和Y 2进行对应频率值的相位补偿操作。
以下，根据第一操作处理的几种不同实现方式，对第一操作处理进行详细描述。
方式一
第一操作处理包括：子载波映射和离散傅里叶反变换。
具体来讲，首先分别对X 1和X 2进行子载波映射，即将X 1和X 2分别映射至不同的物理资源上，然后，对得到的第一路信号进行N 1点的离散傅里叶反变换，对得到的第二路信号进行N 2点的离散傅里叶反变换。最后，再对离散傅里叶反变换后的两路信号分别进行相位补偿操作。
进行离散傅里叶反变换时，N i的取值可以根据X i子载波映射后的子载波间隔f i确定。
比如，在给定的系统带宽大小的条件下，当f 1＝15KHz是，N 1＝4096，当f 2＝30KHz时，N 2＝2048，或者，f 2＝30KHz＝120kHz，N 2＝512。
还应理解，若f 1＝f 2，即两路同步信号的子载波间隔相等，则N 1可以等于N 2；若f 1≠f 2，则N 1可以不等于N 2。
可选地，本申请实施例所涉及的离散傅里叶反变换可以通过IDFT或IFFT实现，但申请实施例并不限于此。
方式二
第一操作处理包括：子载波映射。
即，对X 1和X 2进行子载波映射，即将X 1和X 2分别映射至不同的物理资源上。然后，再对子载波映射后得到的两路信号进行相位补偿操作。
方式三
第一操作处理包括：离散傅里叶反变换。
即，将X 1和X 2分别映射至不同的物理资源上。
情况四
即，Y i是根据对第i路数据的第一操作处理生成的信号。
在此情况下，网络设备首先对X 1和X 2分别进行第一操作处理，得到Y 1和Y 2，然后再分别对Y 1和Y 2进行对应频率值的相位补偿操作。
第一操作处理可以通过上述的方式一或者方式二来实现，具体地可以参照上述描述，为了简洁，此处不再赘述。
S320，对m路第一信号中的第i路信号进行发送处理。
示例性的，所述对m路第二信号中的第i路信号进行发送处理包括：
发送所述m路第二信号；或者，
对所述m路第二信号进行发送预处理，并发送预处理后的信号。
可选地，对所述m路第二信号进行发送预处理，包括：对所述每路第二信号进行离散傅里叶反变换，得到m路经过离散傅里叶反变换后的信号(即，m路第三信号的一例)。
也就是说，m路经过离散傅里叶反变换后的信号为预处理后的信号，或者，还可以对 m路经过离散傅里叶反变换后的信号进行其他的处理，如加循环前缀等，得到预处理后的信号，然后发送预处理后的信号。
进一步地，对所述m路第二信号进行发送预处理还包括：对每路经过离散傅里叶反变换后的信号进行累加。
也就是说，可以先对每路第二信号进行离散傅里叶反变换，然后再对每路经过离散傅里叶反变换后的信号进行累加。累加后的信号可以作为预处理后的信号，或者再对累加后的信号进行其他操作，例如上变频等，得到预处理信号，然后再发送预处理信号。
可选地，对所述m路第二信号进行发送预处理，包括：对所述每路第二信号进行离散傅里叶反变换，并对每路经过离散傅里叶反变换后的信号加循环前缀，得到m路经过加循环前缀后的信号(即，m路第三信号的另一例)。
也就是说，m路经过加循环前缀后的信号为预处理后的信号，或者，还可以对m路m路经过加循环前缀后的信号进行其他的处理，如上变频等，得到预处理后的信号，然后发送预处理后的信号。
进一步地，对所述m路第二信号进行发送预处理还包括：对所述m路第二信号进行发送预处理，还包括：对m路经过加循环前缀后的信号进行累加。
也就是说，可以先对每路第二信号进行离散傅里叶反变换，并对每路经过离散傅里叶反变换后的信号加循环前缀，然后再对m路经过加循环前缀后的信号进行累加。累加后的信号可以作为预处理后的信号，或者再对累加后的信号进行其他操作，例如上变频等，得到预处理信号，然后再发送预处理信号。
举例来说，对应于上述的情况一至情况四，对m路第二信号中的第i路第二信号进行发送预处理分别通过下述的(一)～(四)进行详细说明。
(一)
所述发送预处理可以包括：子载波映射和离散傅里叶反变换。
具体来讲，首先，分别对Z 1和Z 2进行子载波映射，即将Z 1和Z 2分别映射至不同的物理资源上，然后，对得到第一路信号进行N 1点的离散傅里叶反变换，对得到的第二路信号进行N 2点的离散傅里叶反变换。最后，再对离散傅里叶反变换后的两路信号分别进行相位补偿操作。
进行离散傅里叶反变换时，N i的取值可以根据Z i子载波映射后的子载波间隔f i确定。
比如，在给定的系统带宽大小的条件下，当f 1＝15KHz是，N 1＝4096，当f 2＝30KHz时，N 2＝2048，或者，f 2＝30KHz＝120kHz，N 2＝512。
还应理解，若f 1＝f 2，即两路同步信号的子载波间隔相等，则N 1可以等于N 2；若f 1≠f 2，则N 1可以不等于N 2。
进一步地，还可以包括：在离散傅里叶反变换后进行加循环前缀操作。
具体地加循环前缀操作可以参照现有技术，为了简洁，此处不再赘述。

应理解，第一路数据与第一路同步信号对应，第一路数据可以是系统消息，但本申请实施例对此不作限定。
可选地，m路同步信号和r路数据位于同一带宽部分。
可选地，在终端设备根据所述第一差值解调第一数据之前，所述方法还包括：
根据所述第一差值对数据进行相位补偿操作。具体地可以参照网络设备进行相位补偿操作的实现方法，为了简洁，此处不再赘述。
