技术领域
本申请涉及通信领域，并且更具体地，涉及一种参考信号的传输方法及装置。
背景技术
参考信号用于支持接收端设备进行信道估计。参考信号通常只在被调度的物理资源块上发送。参考信号可以占用物理资源块(physical resource block，PRB)中一个符号内的全部12个子载波，以支持最大数量的多个正交天线端口。随着通信技术的发展，出现了新的数据信道传输方式，数据信道及对应的参考信号只能占用PRB中一个符号内的部分子载波，继续沿用当前参考信号在PRB中资源映射的方式将无法支持到最大的正交端口数量。因此，需要设计新的参考信号的资源映射方式。
发明内容

本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通信(global system for mobile communications，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)、免授权频谱的无线通信系统、无线保真(wireless fidelity，WiFi)系统或免授权频谱下的新无线(Unlicensed New Radio,NR-U)等。
图1是本申请实施例可应用的通信系统的场景示意图。如图1所示，该通信系统100包括网络设备102，网络设备102可包括多个天线组。每个天线组可以包括多个天线，例如，一个天线组可包括天线104和106，另一个天线组可包括天线106和110，附加组可包括天线112和114。图1中对于每个天线组示出了2个天线，然而可对于每个组使用更多或更少的天线。网络设备102可附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路116向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(frequency division duplex，FDD)系统中，例如，前向链路116可利用与反向链路120所使用的不同频带，前向链路124可利用与反向链路126所使用的不同频带。

在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。

本申请实施例中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、智慧工厂(smart factory)中的无线终端或制造设备等等。本申请的实施例对应用场景不做限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central  processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。

图2示出了数据通过正交频分复用(orthogonal frequency division multiplexing，OFDM)符号发送之前发送端设备(例如网络设备)所进行的数据处理过程的主要步骤。如图2所示，来自上层(例如，媒体接入控制(media access control，MAC)层)的业务流经过信道编码之后的得到的码字经过加扰、调制、层映射后映射到一个或多层，然后经过预编码处理、资源单元映射，最后将调制后的符号通过天线端口发送出去。相应地，接收端设备(例如终端设备)可以进行解调数据。具体的上述各个数据处理过程可以参见现有标准中的描述。在本申请中，发送端设备可以是网络设备，也可以是终端设备；接收端设备可以是网络设备，也可以是终端设备。
MIMO技术的主要作用是提供空间分集和空间复用增益，MIMO利用多根发射天线将具有相同信息的信号通过不同的路径发射出去，同时在接收端设备可以获取同一 个数据符号的多个独立衰落的信号，从而获得分集提高的接收可靠性，MIMO技术的空间分集可以用来对抗信道衰落。
预编码技术不仅能够有效抑制MIMO系统中的多个用户干扰，而且能在大大简化接收端设备算法的同时显著提升系统容量。预编码技术可以是在已知信道状态的情况下，通过在发送端设备对待发射信号做预先的处理，即借助与信道资源相匹配的预编码矩阵来对待发射信号进行处理，使得经过预编码的待发射信号与信道相适配，使得接收端设备消除信道间影响的复杂度降低。因此，通过对发射信号的预编码处理，接收信号质量(例如信号与干扰加噪声比(signal to interference plus noise ratio，SINR))得以提升。因此，采用预编码技术，可以实现发送端设备与多个接收端设备在相同的时频资源上传输，也就是实现了多用户多输入多输出(multiple user multiple input multiple output，MU-MIMO)。
发送端为了获取能够与信道相适配的预编码矩阵，通常通过发送参考信号的方式来预先进行信道估计，获取接收端的反馈，从而确定出较为准确的预编码矩阵来对待发送数据进行预编码处理。具体地，该发送端可以为网络设备，接收端可以为终端设备，该参考信号可以为用于下行信道测量的参考信号，例如，信道状态信息参考信号(channel state information reference signal，CSI-RS)，终端设备可以根据接收到的CSI-RS，进行CSI测量，并向网络设备反馈下行信道的CSI；该发送端也可以为终端设备，接收端可以为网络设备，该参考信号可以为用于上行信道测量的参考信号，例如，探测参考信号(sounding reference signal，SRS)。网络设备可以根据接收到的SRS，进行信道估计和/或CSI测量，向终端设备指示上行信道的CSI。CSI可以包括例如但不限于预编码矩阵指示(precoding matrix indicator，PMI)、秩指示(rank indication，RI)和信道质量指示(channel quality indicator，CQI)等；为了实现高阶多天线系统的信道质量测量及数据解调，LTE-A系统定义了多种导频信号，其中，解调参考信号(demodulation reference signal，DMRS)用于数据信道，如，物理下行共享信道(physical downlink share channel，PDSCH)或物理上行共享信道(physical uplink shared channel,PUSCH)的解调。
应理解，本申请对于参考信号所适用的通信方式以及参考信号的类型并未特别限定。例如，对于下行数据传输，该发送端例如可以为网络设备，接收端例如可以为终端设备，该参考信号例如可以为信道状态信息参考信号(channel state information reference signal，CSI-RS)；对于上行数据传输，该发送端例如可以为终端设备，接收端例如可以为网络设备，该参考信号例如可以为探测参考信号(sounding reference signal，SRS)；对于设备到设备(device to device，D2D)的数据传输，发送端例如可以是终端设备，接收端例如也可以是终端设备，该参考信号例如可以为SRS或DMRS。
应理解，以上列举的参考信号的类型仅为示例性说明，而不应对本申请构成任何限定，本申请也并不排除采用其他的参考信号以实现相同或相似功能的可能。
下面以DMRS为例，说明参考信号在物理资源块的映射方式。在NR系统中，DMRS支持两种配置方式，图3所示为DMRS端口映射图样，下述配置方式均是基于完整的PRB的端口配置图样。
在第一种DMRS配置方式中：
(1)对于单符号DMRS端口配置图样310，通过序列的两个循环移位以及每个资源块(physical block，RB)中梳齿为2的频分复用(frequency-division multiplexing，FDM)方式，实现最大数量为4的正交端口的支持；其中，端口组1和端口组2采用梳齿为2的频分复用方式实现正交，端口组1中的端口1、端口2占用相同的时频资源，通过序列的两个循环移位实现正交，端口组2中的端口3、端口4占用相同的时频资源，通过序列的两个循环移位实现正交。
(2)对于双符号DMRS端口配置图样320，通过序列的两个循环移位、每个RB中梳齿为2的FDM方式及时域码分复用(code division multiplexing，CDM)(例如时域正交扩频码(orthogonal cover code，OCC)码)方式，实现最大数量为8的正交端口的支持，其中，时域OCC码的长度为2，对应的码序列为{1 1}和{1 -1}；其中，端口组3和端口组4采用梳齿为2的频分复用方式实现正交，端口组4中的端口1至4占用相同的时频资源，通过序列的两个循环移位加长度为2的时域OCC码实现正交，端口组5的端口5至8占用相同的时频资源，通过序列的两个循环移位加长度为2的时域OCC码实现正交。
在第二种DMRS配置方式中：
(1)对于单符号DMRS端口配置图样330，通过频域OCC码、每个RB中梳齿为3的FDM方式，实现最大数量为6的正交端口的支持，频域OCC码的长度为2，频域码序列为{1 1}和{1 -1}；其中，端口组1、端口组2、端口组3采用梳齿为3的频分复用方式实现正交，端口组1中的端口1、端口2占用相同的时频资源，通过长度为2的频域OCC码实现正交，端口组2中的端口3、端口4占用相同的时频资源，通过长度为2的频域OCC码实现正交，端口组3中的端口5、端口6占用相同的时频资源，通过长度为2的频域OCC码实现正交。
(2)对于双符号DMRS端口配置图样340，通过频域OCC码、每个RB中梳齿为3的FDM方式以及时域CDM方式(例如时域OCC码)，实现最大数量为12的正交端口的支持，其中，时域OCC码和频域OCC码的长度为2，时域OCC码对应的码序列为{1 1}和{1 -1}，频域OCC码对应的码序列为{1 1}和{1 -1}；其中，端口组4、端口组5、端口组6采用梳齿为3的频分复用方式实现正交，端口组4中的端口1至4占用相同的时频资源，通过长度为2的频域OCC码加长度为2的时域OCC码实现正交，端口组5的端口5至8占用相同的时频资源，通过长度为2的频域OCC码加长度为2的时域OCC码实现正交，端口组6的端口9至12占用相同的时频资源，通过长度为2的频域OCC码加长度为2的时域OCC码实现正交。
对于一个PRB上所有子载波均用于映射DMRS端口的情形，上述DMRS端口映射图样可以实现最大数量的正交端口，但不适用于其他类型的数据信道传输方式，例如，无法支持子PRB的端口映射。鉴于上述问题，本申请实施例提供了一种传输DMRS的方法，能够支持多种情形下的DMRS端口映射。
下面结合图4描述本申请实施例的方法。图4是根据本发明一个实施例的通信的方法示意性流程图。
401，发送端设备从参考信号资源集合中确定参考信号所占用的资源单元，所述参 考信号资源集合包括T×K个资源单元，所述T×K个资源单元由一个物理资源块PRB的T个连续符号中的每个符号上的K个连续的资源单元组成，其中，一个PRB在所述T个连续符号中的每个符号上包括N个资源单元，T、N和K为正整数且N>K≥1，T≥1，所述T个连续符号中的T×K个资源单元与所述参考信号的至少一个端口组对应，所述至少一个端口组中的每个端口组包括至少两个端口，所述至少一个端口组内的端口对应的参考信号在所述T×K个资源单元上正交复用。
402，接收端设备从所述参考信号资源集合中确定所述参考信号所占用的资源单元。
换句话说，一个PRB中有T个连续符号，在该T个连续符号上有T×N个资源单元，参考信号资源集合为该T×N个资源单元中的T×K个资源单元，该T×K个资源单元位于该T个连续符号上，在该T个连续符号中的每个符号上有K个资源单元属于该参考信号资源集合。发送端设备在该T×K个资源单元上确定参考信号占用的资源单元，该参考信号的至少一个端口组内的端口可以在所述T×K个资源单元上映射，该至少一个端口组包括至少两个端口。相应的，接收端在该T×K个资源单元上确定该参考信号占用的资源单元。
例如，如图5所示，一个PRB包括4个连续的符号(如图5中横向序号1-4所示)，每个符号上有12个资源单元(如图5中纵向序号1-12所示)，参考信号资源集合510由该4个连续符号中的每个符号上的4个连续资源单元组成，即T等于4，N等于12，K等于4，该参考信号资源集合510可以用于映射参考信号；发送端设备在该参考信号资源集合510中确定参考信号所占用的资源单元为符号1中的资源单元1、资源单元2，用于映射该参考信号的端口组1、端口组2，其中，端口组1包括端口1和端口2，端口组2包括端口3和端口4，端口组1的端口在资源单元1上正交复用，端口组2的端口在资源单元2上正交复用；相应的，接收端设备在该参考信号资源集合510中确定该参考信号所占用的资源单元为符号1中的资源单元1、资源单元2。
可选的，该参考信号可以包括小区公共参考信号(cell-specific reference signals，CRS)，解调参考信号(demodulation reference signal，DMRS)，探测参考信号(Sounding Reference Signal,SRS)和信道质量测量参考符号(channel State Information-Reference Signal，CSI-RS)中的至少一种。本申请以DMRS为例进行阐述，应理解，本申请实施例中的方法可以应用于上述参考信号中的至少一种，本申请对此不作限定。
可选的，发送端设备和接收端设备可以按照配置确定参考信号所占用的资源单元。
在一个示例中，发送端设备和接收端设备可以预先设定参考信号在参考信号资源集合中占用的资源单元的信息，例如，发送端设备和接收端设备可以预先定义参考信号优先占用参考信号资源集合中的低频段资源或高频段资源。
在一个示例中，发送端设备和接收端设备可以显式配置参考信号在参考信号资源集合中占用的资源单元的配置信息，例如，发送端设备可以将参考信号所占用的资源单元的配置信息指示给接收端设备，接收端根据发送端设备的指示，确定参考信号所占用的资源单元。
可选的，所述至少一个端口组内的端口对应的参考信号在所述T×K个资源单元上正交复用，包括：所述至少一个端口组内的部分或全部端口对应的参考信号在所述T×K 个资源单元上正交复用。例如，端口组1包括端口1、端口2、端口3、端口4，T为1，K为2，端口1、端口2在资源单元1、资源单元2上正交复用，端口3、端口4在其他资源单元上正交复用，那么，端口组1内的部分端口对应的参考信号在该T×K个资源单元上正交复用。再例如，端口组1包括端口1、端口2，T为1，K为2，端口1、端口2在资源单元1、资源单元2上正交复用，那么，端口组1内的全部端口对应的参考信号在该T×K个资源单元上正交复用。
可选的，所述至少一个端口组内的端口在所述T×K个资源单元上正交复用，包括：所述至少一个端口组内的端口对应的参考信号在所述T×K个资源单元上通过序列的循环移位、码分复用、频分复用和时分复用中的至少一种方式正交复用。
其中，序列的循环移位是指序列在频域上进行线性相位旋转，相当于序列在时域上进行循环移位，相位指的是e ja，a为循环移位参数。由同一个基本参考信号序列进行不同的循环移位后得到的参考信号之间可以相互正交。例如，a设为mπ/6，m可以从0到11，可以从一个基本参考信号序列得到12个不同的正交参考信号。再例如，序列的两次循环移位可以是基于一个基本参考信号序列进行两次不同的循环移位，获得两个不同的正交参考信号序列，该两个正交的参考信号序列可以用于映射不同的端口。例如，与端口1对应的参考信号占用资源单元1且对应的相位为e jπ/6；与端口2对应的参考信号占用资源单元1且对应的相位为e jπ/3，那么，端口1与端口2在资源单元1上正交复用。
其中，码分复用是通过一组互相正交的序列来区分多路信号，实现多路信号在同一资源上复用。例如，码序列{1 1}与码序列{1 -1}之间相互正交，从而码序列{1 1}和码序列{1 -1}可以对应两个不同的端口；再例如，码序列{1 1 1 1}、码序列{1 -1 1 -1}、码序列{j -1 -j 1}和码序列{1 j -1 -j}之间相互正交，码序列{1 1 1 1}、码序列{1 -1 1 -1}、码序列{j -1 -j 1}和码序列{1 j -1 -j}可以对应四个不同的端口。应理解，上述4长的OCC码序列仅为示例，可选地，4长的OCC码序列还可以是码序列{1 1 1 1}、码序列{1 -1 1 -1}、码序列{1 1 -1 -1}和码序列{1 -1 -1 1}。
可选的，码分复用中的正交码可以是时域正交扩频码和/或频域正交扩频码。
在一个示例中，频域OCC码的长度为2，与端口1对应的频域OCC码为{1 1}，与端口2对应的频域OCC码为{1 -1}，那么，端口1与端口2可以在相同的资源上正交复用。
在一个示例中，时域OCC码的长度为4，与端口1对应的时域OCC码为{1 1 1 1}，与端口2对应的时域OCC码为{1 1 1 1}，与端口3对应的时域OCC码为{j -1 -j 1}，与端口4对应的时域OCC码为{1 j -1 -j}，那么，端口1至端口4可以在相同的资源上正交复用。应理解，上述4长的OCC码序列仅为示例，可选地，4长的OCC码序列还可以是码序列{1 1 1 1}、码序列{1 -1 1 -1}、码序列{1 1 -1 -1}和码序列{1 -1 -1 1}。
在一个示例中，频域OCC码的长度为2，时域OCC码的长度为2，与端口1对应的时域OCC码为{1 1}，与端口1对应的频域OCC码为{1 1}，与端口2对应的时域OCC码为{1 -1}，与端口2对应的频域OCC码为{1 -1}，与端口3对应的时域OCC码为{1 1}，与端口3对应的频域OCC码为{-1 -1}，与端口4对应的时域OCC码为{1 -1}，与端口4对应的频域OCC码为{-1 1}，那么，端口1至端口4可以在相同的资源上正 交复用。
其中，频分复用可以是将用于传输信道的频域资源划分成互不重叠的多个频率资源的子集，在该多个频率资源子集上传输多个信号。例如，一个PRB在一个符号内包括12个子载波，其中12个子载波可以被划分成互不重叠的多个子载波组，用于传输多个信号。
其中，时分复用可以是将时间轴划分成若干个单位时间(例如，时隙(slot))，不同的单位时间可以用于传输不同的信号。例如，一个PRB可以被划分为多个符号，该多个符号可以用于传输多个信号。
在一个示例中，参考信号在M个资源单元上通过序列的N次循环移位，可以获得N个相互正交的参考信号序列，那么参考信号在该M个资源单元上可以对应N个端口，M和N为自然数。
在一个示例中，参考信号在一个符号的N个资源单元上通过N个相互正交的频域OCC码，可以获得相互正交的N个参考信号，那么参考信号在该N个资源单元上可以对应N个端口，N为自然数。
在一个示例中，参考信号在N个符号的N个资源单元上通过N个相互正交的时域OCC码，可以获得相互正交的N个参考信号，那么参考信号在该N个资源单元上可以对应N个端口。
在一个示例中，参考信号在一个符号的N个资源单元上通过频分复用的方式，可以对应至少两个端口，N为大于等于2的自然数。
在一个示例中，参考信号在N个符号的N个资源单元上通过时分复用的方式，可以对应至少两个端口，N为大于等于2的自然数。
可选的，所述K个连续的资源单元的位置与发送端设备在一个PRB中数据发送的一个符号上占用的K个连续的资源单元的位置相同。换句话说，该参考信号资源集合中的T个连续符号中的每个符号上的K个连续的资源单元的位置，与数据发送时在每符号占用的K个连续的资源单元的位置相对应。也就是说，可以根据数据发送时所占用的K个连续的资源单元的位置，确定该T×K个资源单元中每个符号上的K个连续的资源单元的位置。例如，该发送端设备在一个符号上发送数据时所占用的资源单元为4个连续的资源单元(资源单元1至资源单元4)，那么，参考信号资源集合包括T×4个资源单元，该T×4个资源单元由一个PRB的T个连续符号中的每个符号上的4个连续的资源单元(资源单元1至资源单元4)组成，该资源单元1至资源单元4的位置与数据发送时每符号内的资源单元1至资源单元4的位置相同。
可选的，至少存在两个不同的K值，与所述至少一个端口组内的端口对应的参考信号在所述T×K个资源单元上的正交复用方式不同。换句话说，该发送端设备可以根据参考信号资源集合所对应的K值，确定参考信号在该参考信号资源集合上的正交复用方式。那么，K可以是与参考信号资源集合对应的配置参数。
例如，在K为3的情况下，该发送端设备可以确定参考信号所对应的端口组1内的端口在T×3个资源单元上使用序列的循环移位和频分复用的正交复用方式，而在K为4的情况下，该发送端设备可以确定参考信号所对应的端口组1内的端口在T×4个资源单元上使用频域OCC码和频分复用的正交复用方式。
