具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
应理解，本发明实施例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、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或下一代通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信。
本发明实施例结合网络设备和终端设备描述了各个实施例，其中：
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。终端设备可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(STAION，ST)，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)设备、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、可穿戴设备以及下一代通信系统，例如，第五代通信(fifth-generation，5G)网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备，新无线(New Radio，NR)通信系统中的终端设备等。
作为示例而非限定，在本发明实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。

另外，在本发明实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
此外，LTE系统或5G系统中的载波上可以同时有多个小区同频工作，在某些特殊场景下，也可以认为上述载波与小区的概念等同。例如在载波聚合(Carrier Aggregation，CA)场景下，当为UE配置辅载波时，会同时携带辅载波的载波索引和工作在该辅载波的辅小区的小区标识(Cell Indentify，Cell ID)，在这种情况下，可以认为载波与小区的概念等同，比如UE接入一个载波和接入一个小区是等同的。
本发明实施例提供的方法和装置，可以应用于终端设备或网络设备，该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，本发明实施例并未对本发明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发明实施例的提供的方法的代码的程序，以根据本发明实施例提供的方法进行通信即可，例如，本发明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。
此外，本发明实施例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/或用于传输指令和/或数据的各种其它介质。
图1是本发明实施例的无线通信系统的示意图。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1个天线或多个天线例如，天线104、106、108、110、112和114。另外，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或终端设备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(也称为下行链路)118向终端设备116发送信息，并通过反向链路(也称为上行链路)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118可与反向链路120使用不同的频带，前向链路124可与反向链路126使用不同的频带。
再例如，在时分双工(Time Division Duplex，TDD)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可使用共同频带，前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。网络设备可以通过单个天线或多天线发射分集向其对应的扇区内所有的终端设备发送信号。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线也可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线或多天线发射分集向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
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。
此外，该通信系统100可以是PLMN网络或者D2D网络或者M2M网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。

作为示例而非限定，作为该用于信道解调的信号可以列举，例如，DMRS或公共参考信号(Common Reference Signal，CRS)等。
并且，本发明实施例中的“数据信道解调”的具体方法和过程可以与现有技术相似，这里，为了避免赘述，省略其详细说明。
再例如，在本发明实施例中，参考信号(具体地说，是上行参考信号)所对应的信道(例如，PUCCH)可以用于传输经调制的控制信息，从而，该参考信号可以用于进行针对该控制信息的解调，该参考信号也称为是该信道的参考信号。

或者，“序列信息”可以是指：序列集合包括的序列所使用的具体序列，具体序列对应的层索引值；
或者，“序列信息”可以是指：序列集合包括的序列所使用的循环移位；
或者，“序列信息”可以是指：序列集合包括的序列所使用的循环移位以及循环移位对应的层索引值。本发明并未特别限定，只要能够使终端设备基于该序列信息确定网络设备所分配的序列集合中包括的各序列即可。
例如，在本发明实施例中，通信系统或通信协议可以规定一个基准序列集合(即，第二序列集合)，并且，作为示例而非限定，该基准序列可以包括Q个序列，从而，该一个序列集合可以包括Q个序列可以与基准序列可以包括Q个序列一一对应，例如，序列集合中的序列#i’的循环移位的取值可以是基准序列中的序列#i的循环移位的取值除以系统规定的预设值(例如，2)后向上取整或向下取整后获得的值，其中，i∈[1，N]。
需要说明的是，在本发明实施例中，“循环移位”可以是指循环移位本身，或者，“循环移位”还可以是指用于计算序列的循环移位中间变量。
下面，对用于传输参考信号的资源进行详细说明。
1.时域
在本发明实施例中，网络设备和终端设备用于传输信息的资源在时域上可以划分为多个时间单元。
并且，在本发明实施例中，该多个时间单元可以是连续的，也可以是某些相邻的时间单元之间设有预设的间隔，本发明实施例并未特别限定。
在本发明实施例中，一个时间单元的长度可以任意设定，本发明实施例并未特别限定。
例如，1个时间单元可以包括一个或多个子帧。
或者，1个时间单元可以包括一个或多个时隙。
或者，1个时间单元可以包括一个或多个迷你时隙。
或者，1个时间单元可以包括一个或多个符号。
或者，1个时间单元可以包括一个或多个传输时间间隔(Transmission Time Interval，TTI)。
或者，1个时间单元可以包括一个或多个短传输时间间隔(short Transmission Time Interval，sTTI)。
或者，1个时间单元可以对应一个时间模式，如第一时间模式为2个符号或3个符号的传输时间间隔，第二模式为7符号的传输时间间隔。
其中，迷你时隙包括一个或多个符号，迷你时隙小于等于时隙，这里的时隙可以是60kHz子载波间隔的系统中的迷你时隙，也可以是15kHz子载波间隔的系统中的迷你时隙，本发明不做限制。
其中，时隙包括一个或多个符号，这里的时隙可以是60kHz子载波间隔的系统中的时隙，也可以是15kHz子载波间隔的系统中的时隙，本发明不做限制。
其中，TTI是目前通信系统(例如，LTE系统)中的普遍使用的参数，是指在无线链路中调度数据传输的调度单位。在现有技术中，通常认为1TTI＝1ms。即，一个TTI为一个子帧(subframe)或者说，两个时隙(slot)的大小，它是无线资源管理(调度等) 所管辖时间的基本单位。
在通信网络中，时延是一个关键的绩效指标，同时也影响着用户的使用体验。随着通讯协议的发展，对时延影响最明显的物理层的调度间隔也越来越小，在最初的WCDMA中，调度间隔是10ms，高速分组接入(High-Speed Packet Access，HSPA)中调度间隔缩短到2ms，长期演进(Long Term Evolution，LTE)中时间间隔(即，TTI)缩短到1ms。
小时延的业务需求导致物理层需要引入更短的TTI帧结构，以进一步缩短调度间隔，提高用户体验。例如，LTE系统中TTI长度可以从1ms缩短为1符号(symbol)到1时隙(包括7个符号)之间。上述提及的符号可以是LTE系统中的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号或单载波频分多址(Single Carrier-Frequency Division Multiple Access，SC-FDMA)符号，还可以是其他通信系统中的符号。又例如，5G通信系统中传输单元长度也小于或等于1ms。
LTE系统在基于长度为1ms的TTI的数据传输中，一般情况下数据传输的来回时间(Round-Trip Time，RTT)为8ms。假设，和现有长度为1ms的TTI的调度相比，处理时间是等比例缩减的，即仍然遵循现有的RTT时延。那么，当基于长度为0.5ms的sTTI的数据传输中，数据传输的RTT为4ms，相对于基于长度为1ms的TTI的数据传输，时延能够缩短一半，从而提高用户体验。
长度小于1ms的TTI可以称为sTTI。例如，LTE系统中，sTTI的长度可以为1～7个符号中任意一种长度，或者，sTTI长度也可以是1～7个符号中至少2种不同长度的组合，例如1ms内包含6个sTTI，各sTTI长度可以分别是3个符号、2个符号、2个符号、2个符号、2个符号、3个符号，或者，1ms内包含4个sTTI，各sTTI长度可以分别是3个符号、4个符号、3个符号、4个符号，各sTTI长度还可以是其他不同长度的组合。
并且，上行的sTTI长度可以和下行的sTTI长度相同，例如上行的sTTI长度和下行的sTTI长度均为2个符号。
或者，上行的sTTI长度可以长于下行的sTTI长度，例如上行的sTTI长度为7个符号，下行的sTTI长度为2个符号。
再或者，上行的sTTI长度可以短于下行的sTTI长度，例如上行的sTTI长度为4个符号，下行的sTTI长度为1个子帧。
TTI长度小于1个子帧或1ms的数据包称为短TTI数据包。短TTI数据传输在频域上，可连续分布，也可非连续分布。需要说明的是，考虑到后向兼容性，系统中可能同时存在基于长度为1ms的TTI的数据传输和基于sTTI的数据传输的情况。
在本发明实施例中，可以将现有技术(例如LTE系统)规定的(例如，长度为1ms或长度大于1ms的)TTI和sTTI统称为TTI，并且，在本发明实施例中，TTI的长度可以根据实际需要进行变更。
应理解，以上列举的时间单元的结构仅为示例性说明，本发明实施例并未特别限定，可以根据实际需要对时间单元的结构进行任意变更，例如，对于不支持sTTI的LTE系统而言，1个时间单元可以为1个子帧(Subframe)。再例如，对于支持sTTI的LTE系统而言，1个时间单元可以包括1个sTTI，或者说，1个时间单元可以包括1个时隙(Slot)，1个时间单元可以包括一个或多个(例如，小于7的正整数个或小于6的正整数个)符号；1个时间单元也可以为1个子帧。
需要说明的是，在本发明实施例中，时间单元用于信息传输的长度(或者说，信息 传输时长)可以是1ms，也可以小于1ms。或者说，结合上述描述，即使对于不支持sTTI的LTE系统而言，当时间单元用子帧表示时，该时间单元内用于下行信息传输的长度可以是1ms，也可以小于1ms，同样地，该时间单元内用于上行信息传输的长度可以是1ms，也可以小于1ms。
为了便于理解和说明，作为示例而非限定，以下，以一个时间单元包括一个sTTI，一个sTTI包括两个符号的情况为例，对本发明实施例的参考信号的传输过程进行详细说明。
并且，在本发明实施例中，网络设备和终端设备用于传输信息的资源在时域上可以划分为多个时间段，每个时间段包括一个或多个时间单元。
作为示例而非限定，在本发明实施例中，一个时间段可以是1ms或10ms。如图3至图5所示，在本发明实施例中，一个时间段可以包括例如6个时间单元或2个时间单元。
作为示例而非限定，在本发明实施例中，用于传输一个参考信号的时域资源(记做：时域资源#β)的位置可以包括以下含义。
含义1
在本发明实施例中，时域资源#β的位置可以是指该时域资源#β相对于用于传输上行信道的时域资源(记做：时域资源#γ)之间的相对位置。这里，该参考信号可以是用于该上行信道的参考信号。
作为示例而非限定，在一个时间段内可以存在p(例如，p＝4)个用于传输参考信号的时间单元(例如，sTTI)，或者说，参考信号的时间单元在时间段内的可能的位置有p个，其中，设上行信道用于传输在该时间段内的第n个时间单元上(即，时域资源#γ为在时间段内的第n个时间单元，或在时间段内的第n个时间单元内的第c个符号)，该p个用于传输参考信号的时间单元(即，时域资源#β)可以为该时间段内的第n-2个时间单元、第n-1个时间单元、第n个时间单元和第n+1个时间单元，其中，n≥3。或者，该p个用于传输参考信号的时间单元(即，时域资源#β)可以为该时间段内的第n-2个时间单元内的第a个符号、第n-1个时间单元内的第b个符号、第n个时间单元内的第c个符号和第n+1个时间单元内的第d个符号，其中，n≥3。
例如，如图3所示，上行信道用于传输于时间单元#4(即，时间段中的第5个时间单元)，则该时间段内用于传输参考信号的时间单元可以为时间单元#2、时间单元#3、时间单元#4或时间单元#5。
含义2
在本发明实施例中，用于传输参考信号的时域资源(即，时域资源#β)的位置可以是指该时域资源#β在通信系统提供的时域资源(例如，每个时间段内的)绝对位置。
作为示例而非限定，例如，如图4所示，在每个时间段内可以存在p(例如，p＝4)个用于传输参考信号的时间单元(例如，sTTI)，并且，作为示例而非限定，如图4所示，该p用于传输参考信号的时间单元可以为每个时间段内的第2个时间单元(例如，图4中的时间单元#1)、第3个时间单元(例如，图4中的时间单元#2)、第4个时间单元(例如，图4中的时间单元#3)和第5个时间单元(例如，图4中的时间单元#4)。即，该时域资源#γ可以是时间单元#1至时间单元#4中的任一个时间单元。
需要说明的是，参考信号可以用于传输于一个时间单元内的全部符号，或者，参考信号也可以用于传输于一个时间单元内的部分符号，本发明并未特别限定。例如，如图4 所示，在时间单元#1、时间单元#2和时间单元#4上，参考信号用于传输于部分符号。在时间单元#3上，参考信号用于传输于全部符号。
另外，对于任意两个用于传输有参考信号的时间单元之间，用于传输有参考信号的符号的位置可以相同，也可以相异，本发明并未特别限定。例如，如图4所示，在时间单元#1上，参考信号用于传输于第二个符号。在时间单元#2上，参考信号用于传输于第一个符号和第三个符号。在时间单元#3上，参考信号用于传输于全部符号。在时间单元#4上，参考信号用于传输于第一个符号。
含义3
在本发明实施例中，时域资源#β的位置可以是指在一个时间单元中的位置，例如，当时域资源#β为一个符号时，时域资源#β的位置可以是指该符号在一个时间单元中的位置。
例如，如图5所示，当时域资源#β为1个符号时，并且，当时域资源#γ包括2个符号且(例如，一个时间段内)第n个时间单元包含时域资源#γ时，其中，n∈[0，N-1]，N为一个时间段包括的时间单元的数量，时域资源#β的位置可以包括以下表现形式：
第n个时间单元可以不包括时域资源#β，也可以不包含时域资源#β。
如果第n个时间单元包含时域资源#β，则时域资源#β可以位于时域资源#γ之前，或者，时域资源#β可以位于时域资源#γ之后。例如，时域资源#β可以位于第n个时间单元中的第一个符号之前，或者，时域资源#β可以位于第n个时间单元中的最后一个符号。
如果第n个时间单元不包含时域资源#β，则时域资源#β可以位于第n个时间单元之前，或者，时域资源#β可以位于第n个时间单元之后。例如，时域资源#β可以位于第n个时间单元之前的第一个符号之前，或者，时域资源#β可以位于第n个时间单元之后的第一个符号。
再例如，如图5所示，当时域资源#β为1个符号时，并且，当第n个时间单元包括3个符号时，时域资源#β的位置可以包括以下表现形式：
第n个时间单元可以不包括时域资源#β，或者说，第n个时间单元中可以不用于传输参考信号，作为示例而非限定，此情况下，第n个时间单元上的符号可以均用于传输上行信道，也可以不用于传输上行信道。
如果第n个时间单元包括时域资源#β且第n个时间单元包括时域资源#γ，则时域资源#β可以位于时域资源#γ之前，或者，时域资源#β可以位于时域资源#γ之后，或者，时域资源#β可以位于两个时域资源#γ之间。
如果第n个时间单元包括时域资源#β且第n个时间单元不包括时域资源#γ，则时域资源#β可以位于第n个时间单元中的第一个符号之前，或者，时域资源#β可以位于第n个时间单元中的最后一个符号，或者，时域资源#β可以位于第n个时间单元中的中间位置的符号。
2.频域
在本发明实施例中，网络设备和终端设备用于传输信息的资源在频域上可以划分为多个频域单元。
并且，在本发明实施例中，该多个频域单元可以是连续的，也可以是某些相邻的频域单元之间设有预设的间隔，本发明实施例并未特别限定。例如预设的间隔为1，或3， 或5，或1+2y，y为整数。
在本发明实施例中，一个频域单元的大小可以任意设定，本发明实施例并未特别限定，例如，一个频域单元可以包括一个或多个子载波。一个子载波在频域上为15k赫兹，或者15k赫兹的整数倍。
需要说明的是，在本发明实施例中，通信系统或通信协议可以规定多种参考信号可以使用的频域单元在系统提供的频域资源上的位置，或者说，通信系统或通信协议可以规定多种参考信号可以使用的频域资源的图案。
例如，在通信系统中的各终端设备采用使用频分复用方式，例如交织频分多址(Interleaved Frequency Division Multiple Access，IFDMA)方式，使用系统提供的用于传输参考信号的频域资源时，通信系统的频域资源(例如，通信系统包括的各频域单元)可以被划分为多种图案，其中，该多种图案中的任意两种图案所包括的频域资源相异。例如子载波索引值为奇数的子载波和子载波索引值为偶数的偶数子载波，或子载波索引值为4z的子载波、子载波索引值为4z+1的偶数子载波、子载波索引值为4z+2的子载波和子载波索引值为4z+3的偶数子载波，其中z为整数。
图6示出了用于传输参考信号的频域资源所划分为的图案，如图6所示，在通信系统中的终端设备的参考信号的频域资源为频分复用方式的频域图案时，图案1对应的频域单元可以被分配给一个终端设备，图案2对应的频域单元可以被分配给另一个终端设备，从而，能够实现两种终端设备在同一时段内，使用不同的频域资源传输参考信号，从而，能够确保各终端设备的参考信号的传输的准确性和可靠性。也可以图案1和图案2被分配给同一个终端设备，从而，能够实现终端设备在同一时段内不同层信号间的准确性和可靠性。
例如，作为示例而非限定，图案1和图案2中的一种图案可以为子载波索引值为奇数的子载波对应的图案，图案1和图案2中的另一种图案可以为子载波索引值为偶数的子载波对应的图案。
应理解，以上列举的频域资源的划分方式仅为示例性说明，本发明并未限定于此，例如，在本发明实施例中，频域资源还可以划分为2种以上(例如，四种)图案。
图7示出了用于传输参考信号的频域资源所划分为的图案的另一例，如图7所示，在通信系统中的终端设备的参考信号的频域资源为频分复用方式的频域图案时，图案1对应的频域单元可以被分配给一个终端设备，图案2对应的频域单元可以被分配给另一个终端设备，图案3对应的频域单元可以被分配给再一个终端设备，图案4对应的频域单元可以被分配给再一个终端设备。从而，能够实现四种终端设备在同一时段内，使用不同的频域资源传输参考信号，从而，能够确保各终端设备的参考信号的传输的准确性和可靠性。也可以图案1、图案2、图案3和图案4被分配给同一个终端设备，从而，能够实现终端设备在同一时段内不同层信号间的准确性和可靠性。
并且，作为示例而非限定，在本发明实施例中，一个终端设备在一次参考信号发送过程中可以仅使用一种图案。
或者，在本发明实施例中，一个终端设备在一次参考信号发送过程中可以使用多种(至少两种)图案。例如，同一参考信号的不同层(或者说，不同子参考信号)之间可以使用不同的图案。例如，设一个参考信号包括4层子参考信号，其中，0层或1层的子参考信号使用的图案与0层或1层的子参考信号使用的图案不同，或其中，0层或1层的 子参考信号使用的子载波索引值的属性与0层或1层的子参考信号使用的子载波索引值的属性不同，子载波索引值的属性可以是奇数或偶数，也可以是4m或4m+1或4m+2或4m+3，m为整数。
类似地，在本发明实施例中，在通信系统中的终端设备的参考信号的频域资源为码分复用方式时，例如，码分复用(Code Division Multiplexing，CDM)方式，使用系统提供的用于传输参考信号的频域资源时，通信系统的频域资源(例如，通信系统包括的各频域单元)可以被划分为一种或多种图案。作为示例而非限定，在通信系统中的终端设备的参考信号的频域资源为码分复用方式的图案时，通信系统内的多个终端设备可以使用同一图案对应的频域资源传输参考信号，即，通信系统的频域资源(例如，通信系统包括的各频域单元)可以被划分为同一种图案，其中，该图案可以包括通信系统中的全部或部分频域单元或部分连续的频域单元，本发明并未特别限定。
图8示出了用于传输参考信号的频域资源所划分为的图案的另一例，如图8所示，在通信系统中的终端设备的参考信号的频域资源为码分复用方式的图案时，通信系统的频域资源(例如，通信系统包括的各频域单元)可以被划分为同一种图案，即，该图案可以包括通信系统中的全部或部分频域单元或部分连续的频域单元，从而，不同的终端设备可以采用不同的码域资源(例如，参考信号的序列的循环移位)，复用该图案对应的频域资源，传输参考信号。从而，能够实现两种终端设备在同一时段内，使用相同的频域资源，基于不同的码域资源，传输参考信号，从而，能够确保各终端设备的参考信号的传输的准确性和可靠性，且减少频域资源的消耗。
另外，以上描述的“图案”仅为资源的频域位置的区分方式的一种，本发明并未特别限定，其他能够区分资源的频域位置的描述方式均落入本发明的保护范围内，例如，“图案”也可以称为“结构(structure)”或“梳齿(comb)”等。
需要说明的是，在本发明实施例中，一个终端设备可以使用一个图案所包括的频域单元中的全部频域单元；或者，一个终端设备可以使用一个图案所包括的频域单元中的部分频域单元；或者，一个终端设备可以使用一个图案所包括的频域单元中的部分连续频域单元，本发明并未特别限定。
并且，在本发明实施例中，在一个符号对应的一个图案中，该符号上的一个图案包括的频域单元可以全部分配给一个终端设备；或者，该符号上的一个图案包括的频域单元可以分配给多个终端设备，并且，各终端设备使用的该图案中的频域单元相异或相同，本发明并未特别限定。
下面，结合图2，对本发明一实施例的参考信号的传输方法200的过程进行详细说明。
在本发明实施例中，网络设备可以与多个终端设备之间传输参考信号，并且，网络设备与每个终端设备传输参考信号的过程相似，为了便于理解，以下，以网络设备与终端设备(即，第一终端设备)之间的参考信号传输过程为例，进行说明。
并且，在本发明实施例中，网络设备与终端设备之间可以传输针对多个上行信道的多个参考信号，并且，每个参考信号的传输过程相似，为了便于理解，以下，以网络设备与终端设备之间传输针对上行信道#A的参考信号(，记做：第一参考信号)的过程为例，进行说明。
如图2所示，在终端设备需要向网络设备传输上行信道(例如，该上行信道可以是用于传输数据和/或控制信息的上行信道，即第一上行信道)时，该终端设备需要发送用 于对该上行信道进行解调的参考信号(即，第一参考信号)。
在S210，该终端设备可以确定用于传输该第一参考信号的资源(即，第一资源)以及该第一参考信号所对应的序列集合(即，第一序列集合)的序列信息。
在本发明实施例中，第一资源可以包括时域上的资源(记作：时域第一资源)和/或频域上的资源(记作：频域第一资源)。
因此，终端设备可以确定用于指示该第一资源在时域上的位置的信息(即，第一资源的时域信息，具体的说，是时域第一资源，记做：信息#1)。
并且，终端设备可以确定用于指示该第一资源在频域上的位置的信息(即，第一资源的频域信息，具体的说，是频域第一资源，记做：信息#2)。
从而，终端设备可以基于该信息#1和信息#2，确定该第一资源。
另外，在本发明实施例中，第一序列集合可以包括Q个序列，Q≥1，其中，Q的值可以是基于该第一参考信号的层数(或者说，包括的子参考信号的数量)确定的，例如，Q的值可以是基于该第一参考信号的层数相同，层索引值为0～Q-1。
终端设备可以确定用于指示该第一序列集合(具体的说，是第一序列集合中的各序列的)序列信息(即，第一序列集合的序列信息，记做：信息#3)。
从而，终端设备可以基于该信息#3，确定该第一序列集合。
在本发明实施例中，“序列信息”可以是指：序列集合包括的具体序列，
或者，“序列信息”可以是指：序列集合包括的序列所对应的具体序列，具体序列对应的层索引值，
或者，“序列信息”可以是指：序列集合包括的序列所对应的循环移位，
或者，“序列信息”可以是指：序列集合包括的序列所对应的循环移位以及循环移位对应的层索引值，本发明并未特别限定，只要能够使终端设备基于该序列信息确定网络设备所分配的序列集合中包括的各序列即可。
作为示例而非限定，在本发明实施例中，在本发明实施例中，通信系统或通信协议中的一个基准序列集合(即，第二序列集合)，并且，作为示例而非限定，第二序列集合包括Q个序列，从而，该第一序列集合包括Q个序列可以与第二序列集合包括Q个序列对应，例如，第一序列集合中的序列#i’的循环移位的取值可以是第二序列集合中的序列#i的循环移位的取值除以预设值(例如，2)后向上取整或向下取整后获得的值，其中，i∈[1，N]。此第二序列集合可以是预先定义的，也可以是高层信令配置的。该预设值可以是预先定义的，也可以是高层信令配置的。
在本发明实施例中，终端设备可以通过以下方式确定信息#1、信息#2和信息#3。
方式1
在本发明实施例中，该信息#3(即，第一序列集合的序列信息)和该信息#1(即，第一资源的时域信息)可以具有映射关系(即，第一映射关系)，或者说，该第一资源在时域上的位置信息与该第一序列集合所包括的序列的循环移位信息可以具有第一映射关系，或者说，该第一资源在时域上的位置信息与该第一序列集合所包括的序列的用于计算循环移位信息的中间变量可以具有映射关系#A。。
可选的，在本发明实施例中，第一参考信号所对应的第一序列集合所包括的序列的循环移位(记作：第一循环移位组)与用于传输该第一参考信号的时间单元(即，第一资源的时域资源，记作：时间单元#A)的索引对应，即不同的时间单元索引对应的序列 相异，需要说明的是，这里的相异可以是序列对应的循环移位相异，也可以是序列对应的循环移位排列相异。例如，当时间单元#A的索引为0(即，时间单元#A为一个时间段内的第一个时间单元)时，通过该时间单元#A中传输的第一参考信号最多对应为4个序列的第一循环移位组可以为(0，6，3，9)或(3，9，6，0)中的一个，或可以为(0，6，3，9)或(6，0，9，3)中的一个，可以理解的是第一循环移位组的子集合(0，6，3，9)中0对应层索引0的循环移位，6对应层索引1的循环移位，3对应层索引2的循环移位，9对应层索引3的循环移位，其他子集合类似定义不再赘述，即，在本发明实施例中，被调度到sTTI#0上的上行第一参考信号对应的循环移位可以被规定为(0，6，3，9)或(3，9，6，0)中的一个。例如，通过该时间单元#A中传输的第一参考信号最多对应为2个序列的第一循环移位组可以为(0，6)或(3，9)中的一个，可以理解的是第一循环移位组的子集合(0，6)中0对应层索引0的循环移位，6对应层索引1的循环移位，第一循环移位组的子集合(3，9)，3对应层索引0的循环移位，9对应层索引1的循环移位。
可选的，在本发明实施例中，第一参考信号所对应的第一序列集合所包括的序列的循环移位(记作：第一循环移位组)与用于传输该第一上行信道的时间单元(即，记作：时间单元#B)的索引对应，即不同的时间单元索引对应的序列相异，需要说明的是，这里的相异可以是序列对应的循环移位相异，也可以是序列对应的循环移位排列相异。举例和之前相似，这里就不再赘述。
可选的，在本发明实施例中，用于传输第一上行信道的时间单元(即，当前被调度的用于传输第一上行信道的时间单元，记作：时间单元#B)，第一参考信号所对应的第一序列集合所包括的序列的循环移位(记作：第一循环移位组)与时间单元#A相对于时间单元#B的时间单元偏移量对应，即不同的时间单元偏移量对应的序列相异，需要说明的是，这里的相异可以是序列对应的循环移位相异，也可以是序列对应的循环移位排列相异。例如，如果时间单元#A和时间单元#B之间的时间单元偏移量为0(即，第一上行信道和第一参考信号用于传输于同一个时间单元)，则第一循环移位组可以为(0，6，3，9)或(3，9，6，0)中的一个，或可以为(0，6)或(3，9)中的一个，也可以为(6，0)或(9，3)；再例如，如果时间单元#A和时间单元#B之间的时间单元偏移量为1(即，时间单元#A为时间单元#B之前的第一个时间单元)，则第一循环移位组可以为(4，10，7，1)或(10，4，1，7)中的一个，也可以为(4，10，7，1)或(7，1，4，10)中的一个，也可以为(4，10)或(7，1)中的一个，也可以为(10，4)或(1，7)；再例如，如果时间单元#A和时间单元#B之间的时间单元偏移量为2(即，时间单元#A为时间单元#B之前的第二个时间单元)，则第一循环移位组可以为(8，2，11，5)或(11，5，8，2)，也可以为(8，2，11，5)或(2，8，5，11)，也可以为(8，2)或(11，5)，也可以为(2，8)或(5，11)；再例如，如果时间单元#A和时间单元#B之间的时间单元偏移量为-1(即，时间单元#A为时间单元#B之后的第一个时间单元)，则第一循环移位组可以为(4，10，7，1)或(10，4，1，7)中的一个，也可以为(4，10，7，1)或(7，1，4，10)中的一个，也可以为(4，10)或(7，1)中的一个，也可以为(10，4)或(1，7)。
可选的，在本发明实施例中，用于传输第一参考信号的时间单元#A为时间单元#B，即第一参考信号与第一上行信道在相同的时间单元中，第一参考信号所对应的第一序列 集合所包括的序列的循环移位(记作：第一循环移位组)与第一参考信号在时间单元#A中的符号索引对应，即不同的符号索引对应的序列相异，需要说明的是，这里的相异可以是序列对应的循环移位相异，也可以是序列对应的循环移位排列相异。例如，当符号索为0(即，时间单元#A中的第一个符号)时，通过该符号中传输的第一参考信号最多对应为4个序列的第一循环移位组可以为(0，6，3，9)或(3，9，6，0)中的一个，或可以为(0，6，3，9)或(6，0，9，3)中的一个，可以理解的是第一循环移位组的子集合(0，6，3，9)中0对应层索引0的循环移位，6对应层索引1的循环移位，3对应层索引2的循环移位，9对应层索引3的循环移位，其他子集合类似定义不再赘述。例如，通过该符号中传输的第一参考信号最多对应为2个序列的第一循环移位组可以为(0，6)或(3，9)中的一个，可以理解的是第一循环移位组的子集合(0，6)中0对应层索引0的循环移位，6对应层索引1的循环移位，第一循环移位组的子集合(3，9)，3对应层索引0的循环移位，9对应层索引1的循环移位。可选的，在本发明实施例中，第一参考信号所对应的第一序列集合所包括的序列的循环移位(记作：第一循环移位组)与时间单元#A和时间单元#B之间的时间单元偏移量和第一参考信号在时间单元#A中符号索引对应。可以理解的是，不同的时间单元偏移量或时间单元#A中的符号索引对应的序列可以相异，也可以不同时间单元偏移量之间对应的序列相异，即相同的时间单元偏移但不同的符号索引对应序列是相同的，也可以不同符号索引之间对应的序列相异，即相同的符号索引但不同的时间单元偏移量对应序列是相同的。需要说明的是，这里的相异可以是序列对应的循环移位相异，也可以是序列对应的循环移位排列相异，这里的相同可以是序列对应的循环移位相同，也可以是序列对应的循环移位排列相同且序列对应的循环移位相同。举例和之前相似，这里就不再赘述。
即，在本发明实施例中，第一参考信号所对应的第一序列集合所包括的序列的循环移位(记作：第一循环移位组)可以与用于承载第一参考信号的符号在时间单元#A中的位置相对应。即，网络设备和终端设备能够根据第一参考信号的索引，确定用于承载第一参考信号的符号在一个时间单元中的位置。
需要说明的是，该时间单元#A可以是当前被调度的用于传输第一上行信道的时间单元，或者，该时间单元#A也可以不是当前被调度的用于传输第一上行信道的时间单元，本发明并未特别限定。可以理解当第一参考信号对应的第一循环移位组包含大于1的子集合，那么终端设备需要根据第五指示信息，确定第一参考信号对应的循环移位。
需要说明的是，之前举例中循环移位(0，6，3，9)等为示例，本发明不做限定。
作为示例而非限定，该映射关系#A可以是指：该信息#3能够基于以该信息#1作为变量的函数确定的。
可选的，在本发明实施例中，上述映射关系#A可以表示为以下式1。

可选的，终端设备可以根据第二指示信息和该信息#1的候选集合，确定信息信息#1，或者，终端设备也可以根据信息#3和该映射关系#A，确定信息信息#1，或者，终端设备也可以根据信息#3、该信息#1的候选集合和该映射关系#A，确定信息信息#1。

本实施例中的一个参数可以是对应的一个索引值，也可以是对应的几个子参数，如几个序列的循环移位，本实施例不做限定。
在本发明实施例中，两个参数集合包括的序列信息相异可以包括：两个参数集合包括的序列信息指示的序列的排序相异，例如，如果参数集合#X和参数集合#Y的序列信息相异，则，参数集合#X包括的序列信息指示的序列可以依次为0，6，3，9，参数集合#Y包括的序列信息指示的序列可以依次为3，9，0，6。

作为示例而非限定，在本发明实施例中，该N个参数集合的信息可以是通信系统或通信协议预先规定的即用户、运营商或制造商设置在网络设备和终端设备中的，或者，该N个参数集合也可以是网络设备通过高层信令发给终端设备的，再或者，该N个参数集合也可以是网络设备通过物理层信令发给终端设备的，本发明并未特别限定，只要确保网络设备和终端设备中存储的N个参数集合的信息相对应(例如，相同)即可。
作为示例而非限定，在本发明实施例中，该N个参数集合可以以表项形式保存在网络设备和终端设备中，例如，该N个参数集合可以对应表项中的N行，并且，每一行包括两个(或两个以上)参数，其中一个参数对应时域信息，另一个参数对应频域信息。再例如，该N个参数集合#1可以对应表项中的N列，并且，每一列包括两个(或两个以上)参数，其中一个参数对应时域信息，另一个参数对应频域信息。
从而，网络设备可以从N个参数集合中选择用于传输第一参考信号的参数集合(即，第一参数集合，记做：参数集合#A)，并且，网络设备可以向终端设备发送该第一参数集合的索引，从而，终端设备可以根据该第一参数集合的索引，确定该第一参数集合，并将该第一参数集合中的参数作为第一资源的信息(例如，第一资源的时域信息和/或第一资源的频域信息)，以及第一序列集合的序列信息。
应理解，以上列举的方式1至方式3可以单独使用也可以结合使用，本发明并未特别限定，例如，在本发明实施例中，上述映射关系#A可以是指：信息#3与信息#1属于上述N各参数集合中的同一个参数集合。此情况下，网络设备可以向终端设备发送信息#3，终端设备可以从N个参数集合中确定该信息#3所属于的参数集合，并且，终端设备可以将同一参数集合中的时域信息作为信息#1。或者，网络设备可以向终端设备发送信息#1，终端设备可以从N个参数集合中确定该信息#1所属于的参数集合，并且，终端设备可以将同一参数集合中的序列信息作为信息#3。
再例如，在本发明实施例中，上述映射关系#B可以是指：信息#3与信息#2属于上述N各参数集合中的同一个参数集合。此情况下，网络设备可以向终端设备发送信息#3，终端设备可以从N个参数集合中确定该信息#3所属于的参数集合，并且，终端设备可以将同一参数集合中的频域信息作为信息#2。
需要说明的是，如上所示，在本发明实施例中，可能存在两种频域资源的使用方式(例如，CDM方式和IFDMA方式)，对此，在本发明实施例中，网络设备还可以向终端设备发送用于指示第一资源的频域使用方式的信息(即，第四指示信息)，从而，终端设备能够根据该第四指示信息，唯一的确定该第一资源的频域使用方式。并且，当第一资源的频域使用方式为IFDMA方式时，终端设备能够根据上述方式1～3中的任意一种方式确定该第一资源对应的频域图案。
综上所述，在本发明实施例中，可以预先配置多个(例如，N个)参数集合，每个参数集合可以包括至少一个时域信息、至少一个频域信息和至少一个序列信息。
其中，时域信息可以指示参考信号的时域位置，其中，该时域位置可以包括承载第一参考信号的时间单元相对于承载第一上行信道的时间单元的时间单元偏移量，或者，该时域位置可以包括承载第一参考信号的时间单元的时间单元索引，或者，该时域位置 可以包括承载第一参考信号的符号索引，或者，该时域位置可以包括承载第一参考信号的符号索引和时间单元偏移量，或者，该时域位置可以包括承载第一参考信号的符号索引和时间单元索引)。
频域信息可以指示参考信号的频域图案，具体地说，采用频分复用方式使用频域资源的频域图案时，频域图案可以包括大于1种的图案。在本发明实施例中，在采用码分复用方式的频域图案时，频域图案可以仅包括一种。
可选的，对于同一个参数集合，码分复用方式对应的序列的个数大于频分复用方式对应序列的个数，或，码分复用方式对应的层子参考信号的个数大于频分复用方式对应层子参考信号的个数。这是因为频分复用后支持的用户数可以随着频分复用方式的图案数增加，这样两种方式对应可支持的总用户数或总层数相同，有利于简化系统分配的复杂度。
需要说明的是，此情况下，作为示例而非限定，网络设备还可以通过例如1个比特，指示终端设备承载第一参考信号的频域资源的是否为频分复用方式。
频域信息可以指示使用的序列的循环移位。
例如，在本发明实施中，该N个参数集合中的(对应同一资源复用方式的)任意两个参数集合之间，至少存在一个相异的参数(即，时域信息、频域信息和序列信息中的至少一个参数)。
从而，在本发明实施例中，例如网络设备可以确定第一参考信号的时域信息、频域信息和序列信息(即，上述信息#1～信息#3)所属于的参数集合(以下，为了便于理解和区分，记做：参数集合#3)，并且，网络设备可以将该参数集合#3的指示信息发送给终端设备，从而，终端设备能够确定参数集合#3，并将参数集合#3中的时域信息、频域信息和序列信息作为上述信息#1～信息#3。
或者，在本发明实施例中，对于时域信息、频域信息和序列信息中的一种信息#a，存在以下条件，(对应同一资源复用方式的)M个参数集合包括的信息#a彼此相异，此情况下，网络设备可以确定参考信号使用的信息#a，并且，网络设备可以将信息#a的指示信息发送至终端设备，从而，终端设备可以根据信息#a唯一的确定该信息#a所属于的参数集合，并将该参数集合中的时域信息、频域信息和序列信息作为上述信息#1～信息#3。
作为示例而非限定，在本发明实施了中，码分复用方式(例如，CDM方式)下参考信号的候选时域位置与频分复用方式(例如，IFDMA方式)下参考信号的候选时域资源位置可以相同也可以不同。
在本发明实施了中，码分复用方式(例如，CDM方式)下参考信号的候选时域位置的数量可以多于频分复用方式(例如，IFDMA方式)下参考信号的候选时域位置的数量。
在本发明实施了中，频分复用方式(例如，IFDMA方式)下参考信号的候选时域位置可以是码分复用方式(例如，CDM方式)下参考信号的候选时域位置的子集。
作为示例而非限定，在本发明实施例中，码分复用方式(例如，CDM方式)下第一参考信号的候选时域位置可以根据第一上行信道所承载于的时间单元的位置的变化而变化。
可选的，在码分复用方式下，当调度信息指示的承载第一上行信道的时间单元n的长度是3个符号时，第一参考信号的候选时域位置可以是在三个时间单元内的时域位置，如时间单元n，时间单元n-1，时间单元n-2中的时域位置。
可选的，在码分复用方式下，当调度信息指示的承载第一上行信道的时间单元n的长度是2个符号)时，，第一参考信号的候选时域位置可以是在四个时间单元内的时域位置，如时间单元n+1，时间单元n，时间单元n-1，时间单元n-2中的时域位置，或时间单元n，时间单元n-1，时间单元n-2，时间单元n-3中的时域位置。
作为示例而非限定，在本发明实施例中，上述第一上行信道(即，基于第一参考信号解调的第一上行信道)可以承载于连续的X(X≥2)个时间单元(即，第二时间单元的一例)。因此，可能存在以下情况：
情况1，承载该第一参考信号的时间单元(即，时间单元#A)属于该X个时间单元
此情况下，在本发明实施了中，设该第一参考信号承载于符号#A，该X个时间单元中与该符号#A之间间隔的符号数量最大的符号(例如，该X个时间单元中的第一个符号，或最后一个符号)为符号#B，则在本发明实施例中，网络设备在确定该符号#A时，可以使该符号#A满足以下条件：
符号#A与符号#B之间间隔的符号数量小于或等于阈值#A(即，第一阈值的一例)。作为示例而非限定，该阈值#A可以为大于或等于2的整数。
情况2，承载该第一参考信号的时间单元(即，时间单元#A)不属于该X个时间单元
对此，存在以下情况：
情况2-A，该时间单元#A与该X个时间单元连续，例如，符号#A与该X个时间单元中的第一个符号或最后一个符号相邻。
此情况下，设该X个时间单元中与该符号#A之间间隔的符号数量最大的符号(例如，该X个时间单元中的第一个符号，或最后一个符号)为符号#C，则在本发明实施例中，网络设备在确定该符号#A时，可以使该符号#A满足以下条件：
符号#A与符号#C之间间隔的符号数量小于或等于阈值#B(即，第二阈值的一例)。作为示例而非限定，该阈值#B可以为大于或等于2的整数。
并且，作为示例而非限定，在本发明实施例中，该阈值#B与上述阈值#A可以相同。
情况2-B，该时间单元#A与该X个时间单元非连续，例如，符号#A与该X个时间单元中的第一个时间单元或最后一个时间单元之间各有至少一个符号。
此情况下，在本发明实施了中，设该X个时间单元与该时间单元#A之间间隔的符号数量大的符号(例如，该X个时间单元中的第一个符号，或最后一个符号)为符号#D，则在本发明实施例中，网络设备在确定该符号#A时，可以使该符号#A满足以下条件：
符号#A与符号#D之间间隔的符号数量小于或等于阈值#C(即，第三阈值的一例)。作为示例而非限定，该阈值#C可以为大于或等于2的整数。
并且，作为示例而非限定，在本发明实施例中，该阈值#C可以小于或等于上述阈值#A，或者，该阈值#C可以小于或等于上述阈值#B。
需要说明的是，在本发明实施例中，网络设备可以采用与上述终端设备相似的方法和过程，基于上述方式1～3中任意一种方式确定与信息#1、信息#2和信息#3，进而，确定该第一资源，并在该第一资源上，接收终端设备发送的第一参考信号。
应理解，以上理解的第一资源的信息(例如，第一资源的时域信息和/或第一资源的 频域信息)与第一参考信号(具体的说，是第一参考信号使用的序列集合)的序列信息之间的具体映射关系仅为示例性说明，本发明并未特别限定，在能够确保网络设备和终端设备基于第一资源的信息和第一参考信号的序列信息中的一方确定出另一方的情况下，可以对映射关系的具体内容进行任意变更。
例如，在本发明实施例中，设在第一参考信号与第一上行信道承载于同一时间单元(例如，sTTI)时第一参考信号能够使用的循环移位的数量为数量#A，设在第一参考信号与第一上行信道承载于不同时间单元(例如，sTTI)时第一参考信号能够使用的循环移位的数量为数量#B，则在本发明实施例中，该数量#A可以大于或等于该数量#B。
另外，作为示例而非限定，在本发明实施例中，网络设备可以将上述信息#1、信息#2、信息#3或第一参数集合的索引承载于下行控制信息(Downlink Control Indicator，DCI)中，并发送给终端设备。
需要说明的是，在本发明实施例中，网络设备可以多次向终端设备发生用于指示终端设备通过第一资源发送参考信号的DCI，并且，该多个DCI中承载的资源的信息、序列信息或参数集合的索引可能相异。
此情况下，终端设备可以基于首次接收到的DCI，进行参考信号的传输，并且，可以忽略之后接收到的DCI。具体的说，在本发明实施了中，终端设备可以根据首次接收到的用于指示在第一资源上传输参考信号的DCI中承载的资源的信息、序列信息或参数集合的索引，确定第一资源的信息、第一序列集合的序列信息。
在本发明实施了中，对于2符号的sPDSCH传输，多个sTTI共享第一参考信号(例如，DMRS)可以减少DMRS的资源开销。如果支持下行数据信道或控制信道的DMRS共享，本发明限制最多允许2个下行(或上行)sTTI共享同一个DMRS且使用1bit来指示，具体可以有以下两种指示方法。(DMRS在一个sTTI上的时域位置和频域图案可以是预先配置的)。
例如，在本发明实施了中，可以用1bit来指示用于解调当前sTTI的DMRS位于前一个sTTI还是后一个sTTI。
再例如，在本发明实施了中，可以用1bit用于指示当前sTTI上是否有DMRS，如果当前sTTI上没有DMRS，那么DMRS一定位于前一个sTTI上。
作为示例而非限定，在本发明实例中，DMRS共享仅用于同一个UE被连续调度sTTI，而不是用于多个UE共享。从而，终端设备仅需要缓存前一个sTTI上的内容，用于判断是否有DMRS，指示比特开销少，且可以达到降DMRS开销的目的。
由此，在S210，终端设备能够确定信息#1，并根据上述信息#1确定第一资源的时域位置。可选的，该终端设备可以通过网络发送的第二指示信息，确定信息#1。
并且，终端设备能够获得信息#2，并根据上述信息#2确定第一资源的频域位置。可选的，该终端设备可以通过网络发送的第三指示信息，确定信息#2。
并且，终端设备能够获得信息#3，并根据上述信息#3确定第一参考信号使用的序列(即，第一序列集合)。可选的，该终端设备可以通过网络发送的第一指示信息，确定信息#3。
在S220，终端设备能够在如上所述确定的第一资源上，基于如上所述确定的第一序列集合，确定发送第一参考信号。
需要说明的是，在本发明实施例中，网络设备可以采用与上述终端设备相似的方法 和过程，基于上述方式1～3中任意一种方式确定与信息#1、信息#2和信息#3，进而，确定该第一资源，并在该第一资源上，接收终端设备发送的第一参考信号。
应理解，以上理解的第一资源的信息(例如，第一资源的时域信息和/或第一资源的频域信息)与第一参考信号(具体的说，是第一参考信号对应的序列集合)的序列信息之间的具体映射关系仅为示例性说明，本发明并未特别限定，在能够确保网络设备和终端设备基于第一资源的信息和第一参考信号的序列信息中的一方确定出另一方的情况下，可以对映射关系的具体内容进行任意变更。
可选的，在本发明实施例中，设在第一参考信号与第一上行信道是位于同一时间单元(例如，sTTI)时第一参考信号能够使用的循环移位的数量为数量#A，设在第一参考信号与第一上行信道#A用于传输于不同时间单元(例如，sTTI)时第一参考信号能够使用的循环移位的数量为数量#B，则在本发明实施例中，该数量#A可以大于或等于该数量#B。
另外，作为示例而非限定，在本发明实施例中，网络设备可以将上述信息#1、信息#2、信息#3或第一参数集合的索引用于传输于下行控制信息(Downlink Control Indicator，DCI)中，并发送给终端设备。
需要说明的是，在本发明实施例中，网络设备可以多次向终端设备发生用于指示终端设备通过第一资源发送参考信号的DCI，并且，该多个DCI中用于传输的资源的信息、序列信息或参数集合的索引可能相异。
此情况下，终端设备可以基于首次接收到的DCI，进行参考信号的传输，并且，可以忽略之后接收到的DCI，也可以是基于最近一次接收到的DCI，进行参考信号的传输。具体的说，在本发明实施了中，终端设备可以根据首次或最近一次接收到的用于指示在第一资源上传输参考信号的DCI中用于传输的资源的信息、序列信息或参数集合的索引，确定第一资源的信息、第一序列集合的序列信息。
根据本发明实施例的发送参考信号的方法，通过使用于传输第一参考信号的第一资源(包括时域资源和/或频域资源)的信息和第一参考信号对应的序列集合(包括至少一个序列)的信息具有映射关系，能够实现在确定第一参考信号对应的序列集合的信息时确定第一资源，从而，能够减小用于传输第一参考信号对应的序列集合的信息和第一资源的信令开销，进而，能够减小上行传输过程的信令开销，提高系统资源的使用效率，提高系统的可靠性。

下面，结合图11，对本发明另一实施例的参考信号的传输方法500的过程进行详细说明。
本发明实施例的方法可以应用于上行传输，即，在本发明实施例中，发送设备可以是终端设备，接收设备可以是网络设备。或者，本发明实施例的方法可以应用于下行传输，即，在本发明实施例中，发送设备可以是网络设备，接收设备可以是终端设备，本发明实施例并未特别限定。
如图11所示，在S510，发送设备确定用于传输第一参考信号(记作：参考信号#a)的第一时间单元(记作，时间单元#A，其中，该时间单元#A可以是例如，一个sTTI)。
需要说明的是，在本发明实施例中，发送设备确定该时间单元#A的方法和过程可以与上述图2所示方法200中描述的用于承载参考信号的时间单元的确定过程相似，例如，该第一时间单元可以是基于该第一参考信号使用的第一序列集合确定的，或者，该第一时间单元可以与基于该第一参考信号使用的第一序列集合属于同一参数集合。
或者，在本发明实施例中，发送设备确定该第一时间单元的方法和过程也可以与现有技术相似，本发明并未特别限定。
其后，发送设备可以确定该第一时间单元包括的符号的数量(记作：数量#a)，并且，发送设备可以确定该第一时间单元在所属于的时间段中的位置(记作：位置#a)。
作为示例而非限定，在本发明实施例中，第一时间单元在所属于的时间段可以是一个子帧，或者，第一时间单元在所属于的时间段的长度可以是1ms。
另外，在本发明实施例中，第一时间单元在所属于的时间段可以包括例如，6个时间单元,例如，该时间段内的时间单元组成为322223或223223，其中2为2个符号，3为3个符号。
并且，发送设备可以根据该数量#a和位置#a，确定用于承载该第一参考信号的符号(记作：符号#a)，具体的说，是符号#a在时间单元#A内的位置。
作为示例而非限定，在本发明实施例中，可以采用以下方法和过程，确定符号#a。
例如，如果数量#a为3，且位置#a为：时间单元#A是所属于的时间段内的第一个时间单元，则发送设备可以确定符号#a是时间单元#A内的第二个符号，或者，发送设备可以确定符号#a是时间单元#A内的最后一个符号。
再例如，如果数量#a为3，且位置#a为时间单元#A是所属于的时间段内的最后一个时间单元，则发送设备可以确定符号#a是时间单元#A内的第一个符号，或者，发送设备可以确定符号#a是时间单元#A内的第二个符号。
再例如，如果数量#a为3，且位置#a为时间单元#A是所属于的时间段内的第三个时间单元，则发送设备可以确定符号#a是时间单元#A内的第一个符号，或者，发送设备可以确定符号#a是时间单元#A内的第二个符号。
由此，在S510，发送设备能够确定用于承载参考信号#a的时间单元#A，以及该时间单元#A内，用于承载该参考信号#a的符号#a。
另外，在本发明实施例中，发送设备还可以确定参考信号#a使用的序列集合，并且，该过程和方法可以与上述方法200中描述的参考序列使用的序列集合的方法和过程相似，例如，参考信号#a使用的序列集合可以是基于该时间单元#A确定的，或者，该时间单元#A可以与基于该参考信号#a使用的序列集合属于同一参数集合。
或者，在本发明实施例中，发送设备确定该时间单元#A的方法和过程也可以与现有技术相似，本发明并未特别限定。
并且，发送设备可以确定用于参考信号#a使用的频域资源，例如，参考信号#a使用的频域图案。
需要说明的是，在本发明实施例中，发送设备确定参考信号#a使用的频域资源(例如，频域图案)的方法和过程可以与上述图2所示方法200中描述的用于承载参考信号的频域资源(例如，频域图案)的确定过程相似，例如，参考信号#a使用的频域资源(例如，频域图案)可以是基于该参考信号#a使用的序列集合确定的，或者，该参考信号#a使用的频域资源(例如，频域图案)可以与基于该参考信号#a使用的序列集合属于同一参数集合。
或者，在本发明实施例中，发送设备确定参考信号#a使用的频域资源(例如，频域图案)的方法和过程也可以与现有技术相似，本发明并未特别限定。
在S520，接收设备可以根据该数量#a和位置#a，确定符号#a，具体的说，是符号#a在时间单元#A内的位置，其中，该过程和方法可以与上述S510中描述的发送设备执行的过程和方法相似，这里，为了避免赘述，省略其详细说明。
从而，在S530，发送设备可以在符号#a向接收设备发送参考信号#a，接收设备可以在符号#a接收发送设备发送的参考信号#a。
由于终端设备的射频可能在子帧的开头、子帧的结尾或者时隙的结尾处进行功率爬坡，导致一个子帧的最后一个符号和第一个符号的发送性能受到影响，根据本发明的发送参考信号和接收参考信号的方法，通过根据承载参考信号的时间单元包括得符号数以及承载参考信号的时间单元在子帧内的位置，确定用于承载参考信号的符号，能够避免将上行参考信号发送在子帧开头和结尾处，从而保证了上行参考信号的性能。
