如图2所示，为本申请一示例性实施例提供的通信方法200的流程示意图，该方法可以但不限于由第一设备(如终端或网络侧设备)执行，具体可由安装于第一设备中的硬件和/或软件执行。本实施例中，所述方法至少可以包括如下步骤。
S210，第一设备传输目标数据。
其中，所述第一设备在进行目标数据传输时，可以但不限于基于混合帧结构实现所述目标数据的传输。为便于理解，如图3所示，本实施例以NR系统、以及混合帧结构为例，对所述ODDM数据与所述OFDM数据的传输过程进行简要说明。其中，假设所述NR系统的每个帧结构不变，即每个时隙(slot)有14个OFDM符号(或称作OFDM调制符号)，其中某1～2个符号上映射的是ODDM符号(或称作ODDM调制符号)在时频(Time Frequency，TF)域的变换符号(简称变换符号，如正交时频空(Orthogonal Time Frequency Space，OTFS))，而除变换符号之外的其他符号上映射的是OFDM调制符号，由此， 实现基于混合帧结构传输所述ODDM数据和OFDM数据的目的。其中，图3中提供了两种映射类型，即映射类型1(Type 1Mapping)和映射类型2(Type 2Mapping)，且映射类型1、映射类型2的不同点在于：ODDM数据和OFDM数据所占据的资源比例不同。其中，所述ODDM数据和OFDM数据分别为不同的用户的数据，如所述ODDM数据为ODDM用户的数据，所述OFDM数据为至少一个OFDM用户的数据。
基于此，在本实施例中，所述目标数据中除了包括ODDM数据和OFDM数据之外，还包括按照预定方式确定的导频信号。所述预定方式可以包括所述ODDM数据与所述OFDM数据分别使用独立导频。其中，此外，“所述ODDM数据与所述OFDM数据分别使用独立理解为：所述ODDM数据所使用的导频与所述OFDM数据所使用的导频相互独立，但二者可以相同或不同。当然，本实施例中，在所述ODDM数据与所述OFDM数据分别使用独立导频时，可以复用相关技术中的导频配置方式，进而使得导频配置方式的实现更加简单。
或者，所述预定方式也可以包括所述ODDM数据与所述OFDM数据使用公共导频，换言之，所述ODDM数据与所述OFDM数据共用导频。其中，本实施例中在进行导频配置上时，通过使用公共导频能够节省导频资源。
需要注意的是，前述的导频信号是作为参考信号使用，如进行信道估计、帧同步等。
本实施例中，所述第一设备在传输ODDM数据和OFDM数据时，按照预定方式确定ODDM数据和OFDM数据所使用的导频信号，其中，所述预定方式包括所述ODDM数据与所述OFDM数据分别使用独立导频，或者，所述ODDM数据与所述OFDM数据使用公共导频。由此，一方面，能够提供一种有效的导频配置方式，以用于数据传输过程中的信道估计等；另一方面，通过所述ODDM数据与所述OFDM数据分别使用独立导频，还能够复用相关技术中的导频配置方式，使得导频配置方式的实现更加简单，或者，通过所述ODDM数据与所述OFDM数据使用公共导频，能够节省导频资源。
如图4所示，为本申请一示例性实施例提供的通信方法400的流程示意图，该方法可以但不限于由第一设备(如终端或网络侧设备)执行，具体可由安装于第一设备中的硬件和/或软件执行。本实施例中，所述方法至少可以包括如下步骤。
S410，第一设备传输目标数据。
其中，所述目标数据中包括ODDM数据和OFDM数据以及按照预定方式确定的导频信号，所述预定方式包括所述ODDM数据与所述OFDM数据分别使用独立导频，或者，所述ODDM数据与所述OFDM数据使用公共导频。
可以理解，S410的实现过程除了可参照方法实施例200中的相关描述之外，作为一种可能的实现方式，所述ODDM数据与所述OFDM数据分别使用独立导频，可以包括：所述ODDM数据使用延迟多普勒域(Delay Doppler，DD)域导频，所述OFDM数据使用频域(Frequency)导频(也可称作TF域导频)；所述ODDM数据使用时域(Time) 导频，所述OFDM数据使用频域导频。
以及，在所述ODDM数据与所述OFDM数据使用公共导频的情况下，所述公共导频被配置在时域。
在此情况下，基于所述导频信号的不同，下面以混合帧结构为例，并结合示例1-示例3对所述第一设备传输目标数据的过程进行说明，内容如下。
示例1
在所述ODDM数据使用DD域导频，所述OFDM数据使用频域导频的情况下，所述第一设备传输目标数据的过程可以包括如下(11)-(12)，内容如下。
(11)将所述ODDM数据以及所述ODDM数据对应的DD域导频在DD域复制映射多次后进行频域变换，得到第一数据。
例如，请结合参阅图5a和图5b，所述ODDM数据和其所对应的DD域导频在DD域进行复制映射后，DD域导频由单份变成了多份，如图5a中的4份，对于其中的一份导频来说，“a1”所指示的部分为导频脉冲/序列，“a2”所指示的部分为导频的保护间隔。
图5a和图5b中所示的ODDM数据和DD域导频变换到TF域后，得到第一数据，可以与OFDM数据以及所述ODDM数据对应的DD域导频组成混合帧结构。其中可以理解，当所述ODDM数据在DD域的延迟/多普勒维度进行K(K大于或等于2)次(倍)的复制(Duplication)映射时，其变换到频域(也可称作TF域)的频率/时间维度会体现为对应维度的数据间进行K-1个零点符号(Zero sample)的插入，以便于OFDM数据及其对应的频域导频的插入。如图5c所示，所述ODDM数据在DD域的延迟/多普勒维度进行4倍的复制(Duplication)映射，那么，其变换到TF域的频率/时间维度会体现为对应维度的数据间进行3个零点符号的插入。
(12)传输所述第一数据、所述OFDM数据以及所述OFDM数据对应的频域导频。
其中，如图5d所示，在图5a或图5b中的ODDM数据和其对应的DD域导频变换到TF域后，得到第一数据时，那么OFDM数据以及所述OFDM数据对应的频域导频可按照相关协议规则，以梳状形式插入第一数据中，其中图5d中的“b1”所指示的部分为OFDM数据所使用的频域导频，“b2”所指示的部分为OFDM数据。
相应的，在所述第二设备接收到所述第一设备发送的目标数据的情况下，对于所述目标数据的中ODDM数据可在DD域进行信道估计，而OFDM数据在频域进行信道估计。此外，对于ODDM数据的信道估计，其可以在图5a、图5b的任一复制区域内进行，也可以综合考虑多个复制区域，即进行合并式信道估计，以进一步提高信道估计的准确性。
此外，示例1中提及的ODDM系统的导频配置方案可以由下行控制信息(Downlink Control Information，DCI)和/或无线资源控制(Radio Resource Control，RRC)信令指示。
示例2
在所述ODDM数据使用时域导频、所述OFDM数据使用频域导频的情况下，所述第一设备传输目标数据的过程可以包括如下(21)-(23)，内容如下。
(21)在所述ODDM数据为零填充(zero padding，ZP)-ODDM数据的情况下，将所述ZP-ODDM数据在DD域复制映射多次后变换至延迟时间(Delay Time，DT)域，得到第二数据。
其中，与示例1类似，通过将所述ZP-ODDM数据在DD域复制映射多次(如K次)后变换至DT域，能够对应维度的数据间存在K-1个零点符号的插入(即第二数据中的数据间存在K-1个零点符号的插入)，以在基于混合帧结构等传输所述第二数据、所述OFDM数据及其对应的频域导频时，用于所述OFDM数据及其对应的频域导频的插入，如图5e所示。
(22)将与所述ZP-ODDM数据对应的时域导频配置在所述第二数据的ZP区域，得到第三数据(如图5e中的ODDM用户对应的ODDM数据)。
其中，所述ZP-ODDM数据是一种ODDM的特殊符号映射方式，即在延时维度的末尾的若干个符号不放置有效信号，以使得DD域等效信道形成带状矩阵，进而使得接收端(或称为接收机，如第二设备)可以利用低复杂度的迭代(Iterative)-RAKE解调算法对ODDM数据进行解调。相关技术中，所述ZP-ODDM中的导频设计还是沿用ODDM的范式，即DD域的导频脉冲/序列+保护间隔的模式，但该设计方式存在导频开销大的问题，对此，在本示例2中，考虑到在ZP-ODDM数据中，DD域符号在延迟维度末尾的零点经过Doppler维度的IDFT变换到DT域后，仍然为零点，因此可以利用ZP-ODDM中末尾的ZP区域(也可称作零点区域)放置时域导频符号，以降低导频开销，例如，如图5e中“c1”所指示的资源。
(23)传输所述第三数据、所述OFDM数据以及所述OFDM数据对应的频域导频(如图5e中的OFDM用户所对应的数据)。
可以理解，本示例2中的OFDM数据的导频映射方式可以参考图5d所示。其中，图5e中“c2”所指示的部分代表此处时间抽头对应的OFDM数据(或称为OFDM符号)上映射有OFDM数据所使用的频域导频。
一种实现方式中，在实现前述(21)-(23)的过程中，考虑到在ZP区域中加入的导频对ODDM数据的干扰程度随导频所占的资源的增加而增加，即导频所占资源越少，对ODDM数据的干扰越小；与此同时，导频的信道估计准确程度亦随导频所占的资源的增加而增加。对此，本示例2中将从如何平衡(trade off)或优化信道估计精度和残留干扰大小这一角度出发，提供一种可选的导频配置模式(即第一导频配置信息)，以供通信系统(如网络侧设备或终端)根据所在场景的信道条件的不同，对导频进行灵活的配置。
例如，对于前述(22)中所述的将与所述ZP-ODDM数据对应的时域导频配置在所述第二数据的ZP区域，得到第三数据这一过程，通过配置第一导频配置信息，可以使得所述第一设备按照第一导频配置信息将所述ZP-ODDM数据对应的时域导频配置在所述第二数据的ZP区域。其中，所述第一导频配置信息中可配置有第一信息、第二信息、第三信息中的至少一项，所述第一信息为所述时域导频在每个所述时域抽头上所占的资源的数 量，所述第二信息为需要进行所述时域导频的配置的时域抽头的索引值，所述第三信息为所述时域导频的密度。
下面根据第一导频配置信息中所包括的信息的不同，对其实现过程进行说明。
第一种实现方式
假定信道的最大时延扩展为L，则ZP-ODDM中的ZP区域大小为大于或等于L。为了尽可能保证信道估计的精确，即尽量避免信号对导频的干扰，需要使当前时间抽头(Time tap)(如图5e中每一个ODDM用户对应的ODDM数据列)中的导频和数据间隔尽量远。对此，可默认ZP-ODDM的时域导频存在于每个ODDM数据所占据的时域抽头上，且起始位置从所述时域抽头(列)的最后一个资源单位开始，如图5f所示。在此情况下，在指示第一设备进行导频配置时，只需要指示每个时域抽头上，导频所占的资源单位数量或个数np即可，其中，np小于或等于L。也就是说，可配置所述第一导频配置信息中仅包括第一信息，使得所述第一设备根据第一信息将与所述ZP-ODDM数据对应的时域导频配置在所述第二数据的ZP区域。
第二种实现方式
在前述第一种实现方式的基础上，假设信道环境较优，那么可以减少导频的密度。例如图5g所示，时域导频存在于部分ODDM用户所占据的时域抽头上，且起始位置从所述时域抽头(列)的最后一个资源单位开始，且导频密度为2。那么，可通过指示一组指示值<kp，np>，或<kp>(即第一导频配置信息)，使得第一设备可基于该指示值进行导频配置，其中np为导频所占的资源单位数量或个数，kp是时域抽头(列)的索引值，即可配置所述第一导频配置信息包括第二信息，或配置所述第一导频配置信息包括第一信息以及第二信息。
需要注意的是，相对于图5f中所示的导频密度为2，图5f中的所示的导频密度为3，即减少了导频密度。
第三种实现方式
在前述第一种实现方式和/或第二种实现方式的基础上，当导频为非连续配置时，如图5h所示，时域导频存在于部分ODDM用户所占据的时域抽头上，且起始位置从所述时域抽头(列)的最后一个资源单位开始。那么，可以通过指示一组指示值<kp，np，dp>，或<dp>,，<kp，dp>，<np，dp>，其中,，np为导频所占的资源单位数量或个数，kp是时域抽头(列)的索引值，dp为导频密度，dp与np的乘积小于或等于L。即所述第一导频配置信息可以包括第三信息，或者，包括第二信息和第三信息，或者，包括第一信息、第二信息和第三信息。
对于前述示例2中提及的第一导频配置信息可以由协议约定、高层配置或网络侧配置实现。例如，在一种实现方式中，所述第一设备可以接收第二指示信息，所述第二指示信息用于配置所述第一导频配置信息。其中，所述第二指示信息可以DCI或RRC信令、系统信息块(System Information Block，SIB)等。例如，可以直接通过RRC或DCI指示第 一导频配置信息，也可以先通过RRC信令指示多组导频配置信息，再通过DCI指示导频配置信息的索引，以用于从多组导频配置信息中选取一组导频配置信息作为第一导频配置信息。
示例3
在所述ODDM数据与所述OFDM数据使用公共导频的情况下，所述第一设备传输目标数据的过程可以包括如下(31)-(33)，内容如下。
(31)在所述ODDM数据为ZP-ODDM数据的情况下，将所述ZP-ODDM数据在DD域复制映射多次后变换至DT域，得到第四数据。
其中，与示例1、示例2类似，通过将所述ZP-ODDM数据在DD域复制映射多次(如K次)后变换至DT域，能够使得对应维度的数据间存在K-1个零点符号的插入(即第四数据的数据间存在K-1个零点符号的插入)，以在基于混合帧结构等传输所述第四数据和所述OFDM数据时，用于所述OFDM数据的插入，如图5i所示。
(32)将所述公共导频配置在所述第四数据的ZP区域，得到第五数据。
其中，与示例2类似，通过将公共导频配置在所述第四数据的ZP区域，能够降低导频开销。
(33)传输所述第五数据和所述OFDM数据。
其中，本示例3与示例2类似。例如，示例3与示例2相同之处在于：本示例3中可以利用ZP-ODDM中末尾的零点放置时域导频符号，而不同之处在于，OFDM用户无需在频域额外放置导频信号。如图5i所示，OFDM用户对应的OFDM符号上没有放置任何导频。
一种实现方式中，所述第一设备将所述公共导频配置在所述第四数据的ZP区域，得到第五数据的过程可以包括：按照第二导频配置信息将所述公共导频配置在所述第五数据的ZP区域；其中，所述第二导频配置信息中配置有第四信息、第五信息、第六信息中的至少一项，所述第四信息为所述时域导频在每个所述时域抽头上所占的资源的数量，所述第五信息为需要进行所述时域导频配置的时域抽头的索引值，所述第六信息为所述时域导频的密度。
可选的，所述第二导频配置信息和所述第一导频配置信息相同或不同，且关于所述第二导频配置信息的相关描述可参照前述关于所述第一导频配置信息的相关描述，以及按照第二导频配置信息将所述公共导频配置在所述第五数据的ZP区域的相关描述可参照前述示例2中“将与所述ZP-ODDM数据对应的时域导频配置在所述第二数据的ZP区域”，并达到相同的技术效果，为避免重复，在此不再赘述。
进一步，对于本示例3中需要使用公共导频的场景，考虑到网络安全，所述公共导频可以使用公共导频标识(ID)生成，而非用UE的私有ID生成。
可选的，所述公共导频ID的获取过程包括：第一设备根据接收到的第一指示信息(如DCI或RRC等)从预配置的导频ID池中选取，其中，所述导频ID池可以为专用于所述 混合帧结构的数据传输。也就是说，所述公共导频的生成可以基于一个混合帧结构专有的公共导频ID池(如导频ID池)，而导频序列的生成基于导频ID池中的导频ID生成。
例如，如果导频采用伪随机序列(Pseudo—Noise Code，PN)序列，则导频ID可能与移位寄存器的初始值，从移位寄存器输出序列中截取导频序列时的偏移值，以及生成Gold序列时的循环位移值有关。
又例如，如果导频采用ZC(Zadoff-Chu)序列，则导频ID可能与ZC序列的根系数有关。
基于此，在一种实现方式中，所述导频ID池可以是协议预配置、高层配置或网络侧配置等实现。例如，所述第一设备可以根据接收到的第二指示信息确定，即所述第二指示信息中指示有所述导频ID池。其中，所述第二指示信息可以是系统信息块(System Information Block，SIB)、RRC、DCI等。可选的，所述第二指示信息可以由第二设备发送等。
例如，可通过SIB或者RRC配置所述导频ID池，再通过RRC或DCI指示导频ID，以使得第一设备基于导频ID从导频ID池中选取导频ID，以进行公共导频的生成。
对于前述示例3中的实现方式，本实施例中也可以定义一个布尔量Fmod来表征ODDM用户和OFDM用户的工作模态。其中，当Fmod＝0时，确定所述ODDM用户和OFDM用户的工作模态为单一帧结构，此时的导频生成和映射按照相关技术中的ODDM数据和OFDM数据的传输方式进行。当Fmod＝1时，确定所述ODDM用户和OFDM用户的工作模态为混合帧结构，此时的ODDM数据和OFDM数据的传输方式为本申请中的给出的传输方式，如导频生成和映射需要按照混合帧结构的方式进行等，即当Fmod＝1时，公共导频的生成基于一个混合帧结构专有的导频ID池生成。
也就是说，在一种实现方式中，所述第一设备可以先确定ODDM用户和OFDM用户的工作模态；以及在所述工作模态为基于混合帧结构进行所述ODDM用户和所述OFDM用户的数据传输的情况下，执行所述传输目标数据的步骤。
进一步，对于前述示例2和示例3中提供的实现方式中，考虑到在ZP-ODDM的ZP部分放置导频符号的方案，可能会破坏ZP-ODDM中数据部分的输入输出关系，导致Iterative-RAKE解调算法的误差平层(error floor)。为此，在本实施例中，在所述第二设备(即接收端)接收到所述第一设备传输的目标数据时，可通过如下(41)-(43)的实现减轻ZP-ODDM时域导频对数据的损害，即在Iterative-RAKE解调算法中引入干扰消除的步骤，内容如下。
(41)所述ODDM数据使用时域导频，所述OFDM数据使用频域导频、且所述ODDM数据为ZP-ODDM数据的情况下，或者，在所述ODDM数据与所述OFDM数据使用公共导频的情况下，基于时域，提取所述目标数据中ZP区域的时域导频进行信道估计得到第一信道信息。
(42)根据指定导频和所述第一信道信息确定导频干扰信息。
其中，所述指定导频是数据收发端(如第一设备、第二设备)均已知格式(如具体值、映射模式等)的导频信号。
(43)从所述目标数据中去除所述导频干扰信息，由此，
通过前述(41)-(43)的实现，可假装接收到的ZP-ODDM数据中不存在导频的干扰，从而继续利用现有的Iterative-RAKE解调算法对其进行解调，以提高数据解调性能。
本实施例中，提供了一种ODDM数据和OFDM数据混合传输时的导频配置方法，且针对独立导频和公共导频的不同场景，提供了几种可选配置方式，并结合ZP-ODDM系统提出了节省开销的时域导频设计方案，能够有效确保数据传输性能。
如图6所示，为本申请一示例性实施例提供的通信方法600的流程示意图，该方法600可以但不限于由第二设备(如终端或网络侧设备)执行，具体可由安装于第二设备中的硬件和/或软件执行。本实施例中，所述方法600至少可以包括如下步骤。
S610，第二设备接收第一设备传输的目标数据。
其中，所述目标数据中包括正交延迟多普勒域调制ODDM数据、正交频分复用OFDM数据以及按照预定方式确定的导频信号，所述预定方式包括所述ODDM数据与所述OFDM数据分别使用独立导频，或者，所述ODDM数据与所述OFDM数据使用公共导频。
可选的，所述ODDM数据与OFDM数据分别使用独立导频，包括：所述ODDM数据使用延迟多普勒域DD域导频，所述OFDM数据使用频域导频；所述ODDM数据使用时域导频，所述OFDM数据使用频域导频。
可选的，在所述ODDM数据与所述OFDM数据使用公共导频的情况下，所述公共导频被配置在时频域。
