首先对本申请实施例涉及的应用场景进行介绍。
本申请实施例的方案可以应用于通信感知一体化(Integrated Sensing And Communication，ISAC)系统中，ISAC系统中集成通信和感知的双重功能，在通信和感知信号之间实现了硬件共用，频谱共享，协议互通，从而实现了通信和感知功能的一体化设计。
ISAC技术面临的最大挑战就是通信和感知的协同工作问题。通信系统的功能是传递信息，因此通信系统的优化目标是逼近信息论中所阐述的香农信道容量；感知系统的功能是目标检测，例如典型的雷达系统，其优化目标则是目标参数(距离，速度，多普勒等)估计方差的最优下限，即模糊函数的Cramér-Rao界。
如图1所示的跨变换域的ISAC系统，具有如下优点。
1)延迟多普勒域的导频块具有时频域的全分集特性，可以进行更加精准的感知检测。
2)延迟多普勒域的导频块可以变换到时频域，与复用在时频域上的数据符号在时频域进行基于OFDM的调制解调，兼容于现有协议。
3)延迟多普勒域的导频块所占用的时频域资源，可以跨多个通信时隙和多个通信子带，与通信系统的参数集设定解耦，适宜于灵活部署。
4)利用所设计二维导频块的优秀自相关和互相关特性，在感知检测时，通信信号的对检测结果的干扰影响可忽略。
但是，感知信号作为干扰，对通信系统解调的影响不可忽视，因此本申请实施例中针对感知信号对通信信号的干扰问题，设计了对应的信号接收处理机制，并定义了相应的信令内容和信令交互流程，从而保障了所提出的通感一体系统中的通信功能。
本申请实施例的方法适用于多用户场景(即感知导频范围覆盖了多个用户的时频域资源)。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的感知导频配置方法进行详细地说明。
请参考图3，本申请实施例提供了一种感知导频配置方法，本实施例的执行主体为发送设备，所述方法包括如下步骤。
步骤101、发送设备向接收设备发送第一信息，第一信息用于指示传输信号中包括的感知导频的配置信息；传输信号为基于感知导频的符号与目标符号在时频域相加得到的，目标符号包括时频域的数据符号和解调参考信号DMRS符号。
在一些实施方式中，发送设备与接收设备之间的传输信号，为基于时频域的感知导频的符号与时频域的目标符号相加得到的。如图4所示，导频块大小为NP×MP,NP≤N,MP≤M，映射在大小为N×M的延迟多普勒域资源中。感知导频经逆辛傅里叶变换(Inverse Symplectic Finite Fourier Transform，ISFFT)变换后(即变换到时频域)与目标符号叠加放置，目标符号例如包括调制后的数据符号(如OFDM调制)以及解调参考信号(Demodulation Reference Signal，DMRS)。
在图4中，导频符号与数据符号叠加放置，且导频符号可以跨数据块(如OFDM的子带/时隙等)进行配置。如图5所示，例如DMRS符号与数据符号资源正交。
可选地，对于OFDM通信系统，其通常利用梳状映射的DMRS进行信道估计，接收机利用所估计的信道进行信道均衡。由于在时频域，信道对信号的作用为乘法，因此可以采用简单的矩阵点除，即用接收到的DMRS点除发送的DMRS，其商矩阵即是所求的信道矩阵。
本申请实施例中，在时频域的感知导频与数据叠加放置，因此所需要考虑的等效DMRS为发送DMRS与对应位置的感知导频之和，即用于信道估计的等效DMRS，为图5中(下方)嵌入在OFDM数据中的DMRS和(上方)感知导频中对应位置的感知导频子集的和。
得到等效导频之后，可以利用常规的信道估计方法获得时频域信道矩阵的估计值。
利用估计信道矩阵，以及感知导频的配置信息(即先验知识)，可以计算在时频域上感知导频对数据的干扰。可选地，可以在信道均衡之前将这个干扰移除。
利用上述方法可以实现与不引入感知导频时基本相同的信道估计和解调结果，如图6和图7所示。
但上述方案实现的前提是，接收设备需要具有感知导频在时频域的先验信息，即发送设备可以向接收设备发送第一信息，用于指示感知导频的配置信息。
本实施例的方法，发送设备向接收设备发送第一信息，第一信息用于指示传输信号中包括的感知导频的配置信息；传输信号为基于感知导频的符号与目标符号在时频域相加得到的，所述目标符号包括时频域的数据符号和解调参考信号DMRS符号；即发送设备向接收设备指示感知导频的配置信息，接收设备可以获知到感知导频的配置信息，从而使得发送设备和接收设备对于感知导频的配置信息具有一致性的理解，便于接收设备进行信号接收处理，提高通信可靠性。
可选地，第一信息可以通过广播、多播或单播等方式进行发送。
一种实现方式a：在第一信息通过广播消息或多播消息发送的情况下，感知导频的配置信息包括以下至少一项：感知导频在延迟多普勒域中的表达形式包含的元素信息；感知导频在时频域域中的表达形式包含的元素信息；用于生成感知导频的基序列的相关信息。
基序列的相关信息包括以下至少一项：基序列、基序列的生成信息。
在一些实施方式中，根据感知导频在符号检测和信道估计中的作用，接收设备通常需要知道如下至少一项信息：感知导频在延迟多普勒域中的表达形式包含的元素信息；感知导频在时频域域中的表达形式包含的元素信息；用于生成感知导频的基序列的相关信息；
其中，感知导频在延迟多普勒域中的表达形式包含的元素，例如可以通过延迟多普勒域矩阵形式S表示，即感知导频在延迟多普勒域中的表达形式包含的元素为在延迟多普勒域中S的矩阵元素。
感知导频在时频域域中的表达形式包含的元素信息，例如可以通过感知导频的时频域形式表示，即通过延迟多普勒域矩阵形式S在时频域的变换形式表示，其中FM表示M点傅里叶变换矩阵，表示N点逆傅里叶变换矩阵，即感知导频在时频域域中的表达形式包含的元素为在时频域中的矩阵元素。
可选地，在其它实施例中，表达形式还可以是集合、数组、序列等，本申请实施例对此并不限定。
基序列用于生成感知导频，例如通过具有良好自相关特性的基序列，可以生成感知导频S。
可选地，所述基序列的生成信息包括以下至少一项：生成参数、生成公式的信息。
在所述基序列为ZC序列的情况下，所述生成参数包括以下至少一项：基序列的根序号，序列长度。
或，在所述基序列为M序列的情况下，所述生成参数包括以下至少一项：基序列的初始值，截取位置，序列长度；所述生成公式的信息包括：M序列的本原多项式的信息。
可选地，广播或多播消息发送的第一信息可以通过物理广播信道(Physical Broadcast Channel，PBCH)或系统消息块(Systeminformation block，SIB)承载。
上述实施方式中，通过广播或多播消息发送感知导频的全局形式的配置信息，可以节省开销，实现了感知导频的先验信息的交互，提升通信接收机的性能。
在步骤101之后，还可以进行如下步骤：发送设备向接收设备发送第二信息，所述第二信息用于指示所述感知导频的时频域位置。
其中，由于通过广播消息或多播消息发送的第一信息，只包括感知导频的全局形式的信息，即包括针对多个接收设备共用的信息，对于特定的接收设备来说，可以通过第二信息，指示该特定的接收设备对应的感知导频的时频域位置，从而获取与DMRS对应的感知导频子集，从而接收设备可以进行信道估计。
其中，接收设备对应的感知导频的时频域位置，即感知导频在时频域映射的资源位置，例如接收设备对应的感知导频在图5中上方资源块中的绝对位置，或接收设备对应的感知 导频与数据资源块的相对位置。
可选地，第二信息可以通过广播消息、多播消息或单播消息发送。
在第二信息通过广播消息或多播消息发送的情况下，所述感知导频的时频域位置通过所述感知导频与时频域资源中参考点的相对位置指示。
或，在第二信息通过单播消息发送的情况下，感知导频的时频域位置通过与所述接收设备的DMRS重叠的感知导频的位置信息指示；所述与所述接收设备的DMRS重叠的感知导频的位置信息为在多个所述接收设备对应的感知导频中的位置索引，或，为相对所述接收设备的DMRS位置索引的偏移值。
在一些实施方式中，(1)通过广播消息或多播消息发送第二信息，在时频域资源中确定一个已知参考点(例如类似NR中的参考点Point A)，指示感知导频与该已知参考点的相对位置。由于此参考点针对通信用户，因此通信用户对应的接收设备可以计算其与感知导频的相对位置，结合第一信息中传递的感知导频的全局形式的配置信息，从而获取DMRS对应位置的感知导频子集。
可选地，广播或多播消息发送的第二信息可以通过PBCH或SIB承载。
(2)通过单播消息发送第二信息，发送设备根据感知导频的时频资源位置和某一接收设备(如OFDM用户)的DMRS的时频资源位置，其中DMRS的时频资源位置由该接收设备所占用的时频资源块位置以及DMRS在所述时频资源块中的位置索引确定，获取计算等效DMRS所需的感知导频子集在感知导频中的位置索引，并将该接收设备对应的感知导频的位置信息发送给对应接收设备。该位置信息可以是感知导频子集在感知导频中的位置索引值，也可以是相对该接收设备的DMRS位置索引值的一个偏移值(offset)。
例如，DMRS在所述时频资源块中的位置索引为一个相对位置，感知导频子集在感知导频中的位置索引也是一个相对位置，由于感知导频子集可以跨多个OFDM帧(例如多个OFDM用户)，因此这两个相对位置(二维坐标)未必一样，所以存在一个offset，感知导频子集在感知导频中的位置索引可以根据相对该接收设备的DMRS位置索引值的一个偏移值，以及接收设备的DMRS位置索引值计算得到。
可选地，单播消息发送的第二信息通过物理资源控制(Radio Resource Control，RRC)消息或下行控制信息(Downlink Control Information，DCI)承载。
上述实施方式中，通过第一信息以及第二信息结合的方式，进行感知导频的配置，使得接收设备可以基于第一信息和第二信息指示的感知导频的信息进行信号数据的处理，消除感知导频对通信的干扰。
另一种实现方式b：在第一信息为通过单播消息发送的情况下，所述感知导频的配置信息为仅针对所述接收设备的配置信息，所述感知导频的配置信息包括：与所述DMRS重叠的感知导频的信息。
在一些实施方式中，发送设备发送单播消息，分别直接指示各个接收设备对应的配置信息，如感知导频子集。可选地，发送设备根据感知导频的全局形式的配置信息，感知导 频映射的时频域位置和某一接收设备的DMRS映射位置，获取计算等效DMRS所需的感知导频子集，即与DMRS重叠的感知导频的信息，即感知导频与数据块中DMRS重叠位置的感知导频的信息，如感知导频在延迟多普勒域或时频域中的矩阵元素信息，并将该与DMRS重叠的感知导频的信息发送给该接收设备。该接收设备利用接收到的与DMRS重叠的感知导频的信息，以及自身DMRS直接相加得到所需的等效DMRS。
可选地，单播消息发送的第一信息可以承载在RRC消息中。
上述实施方式中，通过单播消息发送针对特定接收设备的配置信息，使得接收设备可以直接使用该配置信息进行信号数据的处理，消除感知导频对通信的干扰。
可选地，该方法还包括：所述发送设备向所述接收设备发送第一指示信息，所述第一指示信息用于指示是否需要进行干扰消除。
例如在通信信道条件较好的场景下，可以容忍感知导频的存在，将感知导频作为噪声处理，此时可以不需要进行第二信息的指示，可以通过发送第一指示信息，指示是否需要进行干扰消除，有利于根据信道条件进行接收设备的工作方式(或状态)的动态调整。
例如，接收设备的状态包括：将感知信号作为干扰处理的状态，或，将感知信号作为噪声处理的状态。
如果当前状态为将感知信号作为噪声处理的状态，接收到第一指示信息用于指示需要进行干扰消除，则接收设备会更新当前状态为将感知信号作为干扰处理的状态。
第一指示信息例如通过1bit或2bit信令传递。
可选地，第一指示信息通过以下至少一项承载：同步信号块(Synchronization Signal and PBCH block，SSB)，PBCH，参考信号，DCI，媒体接入控制元素(Medium Access Control Control Element，MAC CE)，SIB，加扰的物理下行控制信道(Physical Downlink Control Channel，PDCCH)信令。
上述实施方式中，通过第一指示信息，可以灵活调整接收设备的工作方式或状态。
可选地，该方法还包括：发送设备接收所述接收设备发送的第二指示信息，所述第二指示信息用于进行与感知导频的配置信息相关的指示。
在一些实施方式中，接收设备根据发送设备的配置信息，对接收到的信号数据进行解调译码。接收设备可以基于当前状态以及误码率，发送必要的反馈信息以开展自适应处理，例如指示发送设备是否发送感知导频的配置信息，可以节省开销，以及灵活配置信息，从而提高通信可靠性。
可选地，所述第二指示信息用于指示所述发送设备发送所述感知导频的配置信息。
或，所述第二指示信息用于指示所述发送设备不发送所述感知导频的配置信息。
或，所述第二指示信息用于指示所述发送设备对所述感知导频的配置信息进行调整。
在一些实施方式中，接收设备根据发送设备指示的误码率上限值Eh和误码率下限值El判断是否需要调整配置。假设接收设备侧确定的实际误码率为Et。根据实际误码率是否大于误码率上限值Eh，或小于误码率下限值El，接收设备向发送设备发送第二指示信息，用 于反馈发送设备是否需要发送感知导频的配置信息，或指示发送设备对感知导频的配置信息进行调整。
可选地，第二指示信息通过以下至少一项承载：SSB，PBCH，参考信号，DCI，MAC CE，SIB，加扰的PDCCH信令。
可选地，在第二指示信息用于指示所述发送设备对所述感知导频的配置信息进行调整的情况下，发送设备接收所述接收设备发送的第二指示信息之后，还包括：对所述感知导频的功率进行调整，并基于调整后的感知导频的功率，更新所述感知导频的配置信息。
在一些实施方式中，在误码率较大的情况下，接收设备向发送设备发送第二指示信息，用于指示对感知导频的配置信息进行调整，发送设备基于该第二指示信息调整感知导频的功率，可以是降低感知导频的功率，即调整导频和数据间的功率分配。
例如，上述情况出现在总功率受限时，感知导频分流了通信信号的部分功率，造成通信信道质量较差(如SINR较低)，无法满足解调需求。
发送设备根据接收设备反馈的第二指示信息，调整导频和数据间的功率分配。
可选地，对所述感知导频的功率进行调整，包括：将所述感知导频的功率调整为预设的至少一组感知导频和数据的功率信息中的感知导频的功率；或，基于预设的调整步长，减少所述感知导频的功率。
在一些实施方式中，从预设的表格中重配置一组感知导频的功率和数据块的功率，该组中感知导频的功率小于调整前感知导频的功率。
或，根据预配置的调整步长Δp，减少感知导频的功率，相应增大数据块的功率。
上述实施方式中，通过对感知导频的功率进行调整，可以提高通信可靠性。
图8是本申请实施例提供的感知导频配置方法的流程示意图之二，如图8所示，本实施例的执行主体为接收设备，该方法包括：
步骤201、接收设备接收发送设备发送的第一信息，第一信息用于指示传输信号中包括的感知导频的配置信息；传输信号为基于感知导频的符号与目标符号在时频域相加得到的，目标符号包括时频域的数据符号和解调参考信号DMRS符号。
具体地，本实施例中提供了一种通信接收机的处理方式。
接收设备根据发送设备发送的感知导频的配置信息，对接收到的信号数据进行解调译码。
可选地，所述方法还包括：所述接收设备基于误码率，向所述发送设备发送第二指示信息，所述第二指示信息用于进行感知导频的配置信息相关的指示。
可选地，在所述接收设备的当前状态为第一状态，且实际误码率大于或等于误码率上限值的情况下，所述第二指示信息用于指示所述发送设备发送所述感知导频的配置信息；所述第一状态为将感知信号作为噪声处理的状态；在所述接收设备的当前状态为第二状态，且所述实际误码率小于误码率下限值的情况下，所述第二指示信息用于指示所述发送设备不发送所述感知导频的配置信息；所述第二状态为将感知信号作为干扰处理的状态；
在所述接收设备的当前状态为第二状态，且所述实际误码率大于或等于误码率上限值的情况下，所述第二指示信息用于指示所述发送设备对所述感知导频的配置信息进行调整。
可选地，在所述第一指示信息用于指示需要进行干扰消除的情况下，所述接收设备的当前状态为第二状态；所述第二状态为将感知信号作为干扰处理的状态；在所述第一指示信息用于指示不需要进行干扰消除的情况下，所述接收设备的当前状态为第一状态；所述第一状态为将感知信号作为噪声处理的状态。
在一些实施方式中，接收设备根据发送设备指示的误码率上限值Eh和误码率下限值El判断是否需要调整配置。假设接收设备侧确定的实际误码率为Et。根据实际误码率是否大于误码率上限值Eh，或小于误码率下限值El，接收设备向发送设备发送第二指示信息，用于反馈是否需要发送设备发送第一信息。
假设接收设备的当前状态为第二状态(rstat＝1)时，接收设备将感知信号作为干扰处理，当前状态为第一状态(rstat＝0)时，接收设备将感知信号作为噪声处理。
当rstat＝0，Et>Eh时，接收设备向发送设备发送第二指示信息，例如携带istat＝1要求进行感知导频的配置信息的传递，以便切换到rstat＝1进行干扰消除提升接收机性能。可选地，第二指示信息可以携带以下信息：[istat,rstat]＝[1,0]。
当rstat＝1，Et<El时，接收设备向发送设备发送第二指示信息，例如携带istat＝0要求不必进行感知导频的配置信息的传递，以节省开销。可选地，第二指示信息可以携带以下信息：[istat,rstat]＝[0,1]。
当rstat＝1，Et>Eh时，接收设备向发送设备发送第二指示信息，例如携带istat＝1要求进行感知导频的配置信息的调整，以确保通信正常进行。可选地，第二指示信息可以携带以下信息：[istat,rstat]＝[1,1]。调整方式包括降低感知导频功率(即调整导频和数据间的功率分配)。
