Description

一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
感知技术是指将电磁能量发射至空间中，空间中的物体在接收到电磁能量后反射电波，基于物体反射的电波可以计算出该物体的相关信息，例如位置、方向、高度、速度、大小等。5G及之后演进的通信技术中，通信设备通过发送感知信号从环境中获取感知信息会成为重要的手段。例如在自动驾驶场景中，车辆通过发送感知信号，感知前方环境中是否有障碍物以及感知障碍物的相关信息。
由于通信设备在通过发送感知信号的同时需要兼顾与其它通信设备之间的通信业务，因此可以将通信信号和感知信号进行混合传输。但通信信号和感知信号复用时频资源进行混合传输会对通信信号的信噪比和解调造成一定影响。
如何降低通信信号和感知信号混合传输对通信性能的影响，是亟待解决的问题。

本申请提供的技术方案可以应用于各种通信系统，例如：可以应用于第4代(4th generation，4G)通信系统，例如长期演进(long term evolution，LTE)系统，或应用于第五代(5th generation，5G)通信系统，例如新无线(new radio，NR)系统，或应用于5G之后演进的各种通信系统，例如，第六代(6th generation，6G)通信系统。本申请还可以应用于卫星通信等的各种通信系统等。
图1示出了本申请实施例提供的通信方法适用的一种通信系统的架构，所述通信系统的架构中可以包括第一装置10和第二装置11。
第一装置10或第二装置11可以为任意一种具有无线收发功能的通信设备，或者，可以为设置于具有无线收发功能的通信设备中的芯片；通信设备包括但不限于终端设备、网络设备。
该网络设备包括但不限于：5G基站(gNB)、LTE中的演进型基站(evolved Node B，eNB或eNodeB)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP)或者发射点(transmission point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备、无人机通信中承担基站功能的设备等，还可以包括云接入网(cloud radio access network，C-RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)、非陆地通信网络(non-terrestrial network，NTN)通信系统中的网络设备，即可以部署于高空平台或者卫星。本申请实施例对此不作具体限定。
所述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、移动终端、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)、智能手机、平板电脑(Pad)、带无线收发功能的电脑、车载通信装置、高空飞机上搭载的通信设备、可穿戴设备、无人机、机器人、智能销售点(point of sale，POS)机、客户终端设备(customer-premises equipment，CPE)、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、个人数字助理(personal digital assistant，PDA)等等。本申请的实施例对应用场景不做限定。
本申请实施例第一装置10向第二装置11发送通信信号和感知信号，通信信号中包括导频信号，第二装置11在接收到通信信号和感知信号后，根据通信信号中包括的导频信号进行信道估计，并根据接收到的通信信号处理第一装置10的通信业务，根据接收到的感知信号对目标进行感知。
其中，通信信号为第一装置和第二装置之间传输的以实现无线通信功能为主的信号；感知信号为用于感知周围环境、以对环境中的目标进行感知为主要功能的信号。
本申请的通信系统可以适用于终端设备与网络设备之间进行通信的场景。如图2所示，本申请实施例的第一装置10可以为终端设备，第二装置11可以为网络设备。终端设备在相同的传输资源上向网络设备发送通信信号和感知信号；网络设备在接收到通信信号和感知信号后，根据通信信号中包括的导频信号进行信道估计，并根据接收到的通信信号处理终端设备的通信业务，根据接收到的感知信号对空间中目标进行感知，从而网络设备可以检测到目标的相关信息，例如位置、方向、高度、速度、体积大小等信息。

需要说明的是，图1、图2、图3所示的通信系统的架构仅仅作为示例，图1、图2、图3并不限定本申请适应的通信系统的架构的组成。图1、图2、图3中还可以包括更多的设备，本申请此处不再示出。
目前第一装置在相同传输资源上向第二装置同时发送通信信号和感知信号，将通信信号和感知信号在相同传输资源上混合传输。第二装置在接收到通信信号之后，根据通信信号中的导频信号进行信道估计，但由于通信信号和感知信号复用时频资源，第二装置接收到的是叠加了感知信号的导频信号，会破坏导频信号的恒模特性，导致第二装置在进行导频信道估计时信噪比起伏较大，尤其对于叠加后模值较小的导频信号，在相同的底噪下出现信噪比偏小的情况，影响信道估计的准确性。
基于此，本申请提出多种传输通信信号和感知信号的方案，用以在通信信号和感知信号复用时频资源进行混合传输时，使接收端根据接收到的导频可以准确进行信道估计。下面针对多种传输通信信号和感知信号的方案分别进行说明：
方案一：在通信信号中导频信号占用的传输资源外的其它传输资源上发送感知信号。
本申请实施例提出一种通信方法，适用于图1、图2或图3所示的通信系统。参阅图4所示，该方法的具体流程可以包括：
步骤401：第一装置在目标传输资源上向第二装置发送通信信号和感知信号，相应地，第二通信装置在该目标传输资源上接收通信信号和感知信号；
其中，通信信号包括导频信号和非导频信号，非导频信号占用的传输资源和感知信号占用的传输资源有重叠，感知信号不占用用于传输导频信号的传输资源。
本申请实施例第一装置向第二装置发送的通信信号中包括导频信号和除导频信号之外的非导频信号；导频信号是第一装置和第二装置双方已知的信号。第二装置根据接收到的导频信号与发送前通信信号中的导频信号，对传输通信信号和感知信号的信道进行信道估计。
本申请实施例将通信信号中除导频信号之外的部分称为非导频信号，非导频信号可以用于传输数据或者信令等信息。如图5所示的通信信号的传输结构，其中有阴影填充的位置为导频信号占用的传输资源，其它位置上传输的为非导频信号，非导频信号携带第一装置向第二装置发送的数据或信令等信息。
本申请实施例第一装置在向第二装置发送通信信号和感知信号时，在目标传输资源上同时向第二装置发送通信信号和感知信号。但是为了避免通信信号和感知信号复用传输资源时，感知信号对通信信号中的导频信号造成影响，本申请实施例在导频信号占用的资源上不传输感知信号。第一装置在向第二装置发送通信信号和感知信号之前，需要先确定通信信号和感知信号占用的传输资源。
本申请实施例感知信号不复用传输导频信号所占用的传输资源，且感知信号占用的传输资源与非导频信号占用的传输资源部分重叠或全部重叠。
基于上述资源分配方式，第一装置可以在目标传输资源上连续发送通信信号，而针对感知信号，第一装置在目标传输资源中除导频信号占用的传输资源之外的部分或全部资源上发送感知信号。因此，本申请实施例可以根据通信信号中导频信号占用的传输资源，确定目标传输资源中感知信号未占用的传输资源。
本申请实施例的传输资源包括时域资源和频域资源。其中时域资源包括一个或多个时间单元，一个时间单元可以包括一个或多个对时域划分的最小粒度，例如一个时间单元包括一个或多个正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)符号，或者一个时间单元包括一个或多个正交振幅调制(Quadrature Amplitude Modulation，QAM)符号。频域资源包括频域单元，频域单元可以包括一个或多个对频域划分的最小粒度，例如一个频域单元包括一个或多个子载波。
实施中，本申请实施例提供多种感知信号的资源分配方式：
方式1、感知信号不复用通信信号中导频信号占用的第一时域资源和通信信号中导频信号占用的频域资源对应的传输资源块。
其中，通信信号中导频信号占用的第一时域资源包括一个或多个时间单元，通信信号中导频信号占用的频域资源包括一个或多个频域单元。
如图6所示的目标传输资源中通信信号的资源分配方式，其中有阴影填充的位置为通信信号中导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。时域方向上T1、T2、T3、T4、T5表示一个时间单元，频域方向上f 0、f 1、f 2……f N-1表示一个频域单元，通信信号中导频信号占用的第一时域资源为时间单元T2，通信信号中导频信号占用的频域资源为f 0、f 2；则基于该种资源分配方式，感知信号不占用通信信号中导频信号占用的传输资源，即感知信号未占用的传输资源包括：时间单元T2和频域单元f 0对应的传输资源块、以及时间单元T2和频域单元f 2对应的传输资源块。
假设感知信号为如图7所示的周期信号，由于在目标传输资源中感知信号未占用的传输资源包括：时间单元T2和频域单元f 0对应的传输资源块、以及时间单元T2和频域单元f 2对应的传输资源块，则在目标传输资源中传输的感知信号如图8所示，在时间单元T2和频域单元f 0对应的传输资源块、以及时间单元T2和频域单元f 2对应的传输资源块上不传输感知信号。
本申请实施例提供的该种资源分配方式可以根据通信信号中导频信号占用的传输资源，将导频信号占用的传输资源作为感知信号未占用的传输资源，在发送感知信号过程中，需要精准控制在导频信号占用的传输资源上不发送感知信号。这种方式可以适用于在数字域上生成的感知信号，可以精确控制在导频信号占用的传输资源上不发送感知信号。
方式2、感知信号不复用通信信号中导频信号占用的第一时域资源和目标传输资源的全部频域资源对应的传输资源块。
如图6所示的目标传输资源中通信信号的资源分配方式，其中有阴影填充的位置为通信信号中导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。时域方向上T1、T2、T3、T4、T5表示一个时间单元，频域方向上f 0、f 1、f 2……f N-1表示一个频域单元，通信信号中导频信号占用的第一时域资源为时间单元T2，通信信号中导频信号占用的频域资源为f 0、f 2；基于该种资源分配方式，感知信号不占用通信信号中导频信号占用的第一时域资源和目标传输资源的全部频域资源共同确定出的传输资源块，即感知信号未占用的传输资源包括：时间单元T2与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块，如图9中有阴影填充的位置为感知信号未占用的传输资源。
假设感知信号为如图7所示的周期信号，由于在目标传输资源中感知信号未占用的传输资源包括：时间单元T2与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块，则在目标传输资源中传输的感知信号如图10所示，在时间单元T2与全部频域单元f 0、f 1、f 2……f N-1 确定出的传输资源块上不传输感知信号。
本申请实施例提供的该种资源分配方式可以根据通信信号中导频信号占用的第一时域资源和目标传输资源中的全部频域资源，确定感知信号未占用的传输资源；该种方式可以适用于无法精确控制感知信号不在某个频域单元上传输的场景(例如通过模拟振荡器生成的感知信号)，在第一时域资源对应的时间范围内，在目标传输资源的全部频域资源上不发送感知信号，因此可以更为便利地根据感知信号未占用的传输资源对感知信号的传输进行控制，同时对信号处理和/或硬件的要求较低。
方式3、感知信号不复用通信信号中导频信号占用的第一时域资源以及与第一时域资源相邻的第二时域资源、和目标传输资源的全部频域资源对应的资源块。
如图6所示的目标传输资源中通信信号的资源分配方式，其中有阴影填充的位置为通信信号中导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。时域方向上T1、T2、T3、T4、T5表示一个时间单元，频域方向上f 0、f 1、f 2……f N-1表示一个频域单元，通信信号中导频信号占用的第一时域资源为时间单元T2，通信信号中导频信号占用的频域资源为f 0、f 2；基于该种资源分配方式，感知信号不占用通信信号中导频信号占用的第一时域资源以及与第一时域资源相邻的第二时域资源、和目标传输资源的全部频域资源共同确定出的传输资源块。
其中，与第一时域资源相邻的第二时域资源包括M个时间单元，所述M大于或等于1。
M取值为1时，感知信号未占用的传输资源中时域资源包括通信信号中导频信号占用的第一时域资源、第一时域资源的前一个时间单元以及第一时域资源的后一个时间单元。如图11所示，感知信号未占用的传输资源中时域资源包括通信信号中导频信号占用的时间单元T2、时间单元T1和时间单元T3，感知信号未占用的传输资源为时间单元T1、T2、T3与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块，如图11中有阴影填充的位置为感知信号未占用的传输资源。
假设感知信号为如图7所示的周期信号，由于在目标传输资源中感知信号未占用的传输资源包括：时间单元T1、T2、T3与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块；则在目标传输资源中传输的感知信号如图12所示，在时间单元T1、T2、T3与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块上不传输感知信号。
本申请实施例提供的该种资源分配方式可以根据通信信号中导频信号占用的第一时域资源、与第一时域资源相邻的第二时域资源和目标传输资源中的全部频域资源，确定感知信号未占用的传输资源；为了进一步减小感知信号对通信信号中导频信号的影响，并且可以更好的控制感知信号传输，可以在通信信号中导频信号占用的第一时域资源之前和之后一定时长内也不传输感知信号。该种方式可以适用于无法精确控制感知信号不在某个频域单元上传输的场景(例如通过模拟振荡器生成的感知信号)，在第一时域资源和与第一时域资源相邻的第二时域资源对应的时间范围内，在目标传输资源的全部频域资源上不发送感知信号，因此可以更为便利地根据感知信号未占用的传输资源对感知信号的传输进行控制，同时对信号处理和/或硬件的要求较低。
方式4、感知信号不占用第三时域资源和目标传输资源的全部频域资源对应的传输资源块；
其中，第三时域资源的长度为N个连续感知信号的周期，N大于或等于1，且第三时 域资源包括通信信号中导频信号占用的第一时域资源。
在该种方式下，本申请实施例的感知信号为周期信号，为了便于更好的控制感知信号传输，可以在一个或多个的感知信号周期内不传输感知信号。
一种可选的实施方式为，在确定第三时域资源时，可以将包括通信信号中导频信号占用的第一时域资源的一个或多个感知信号的周期作为第三时域资源。
如图13所示的目标传输资源中通信信号的资源分配方式，其中有阴影填充的位置为通信信号中导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。时域方向上T1、T2、T3、T4、T5、T6、T7、T8表示一个时间单元，频域方向上f 0、f 1、f 2……f N-1表示一个频域单元，通信信号中导频信号占用的第一时域资源为时间单元T4，通信信号中导频信号占用的频域资源为f 0、f 2；基于该种资源分配方式，感知信号未占用的传输资源包括第三时域资源和目标传输资源的全部频域资源共同确定出的传输资源块。
假设感知信号为如图14所示的周期信号，感知信号的一个周期为两个时间单元，感知信号周期t2包括通信信号中导频信号占用的第一时域资源，感知信号周期t2对应于时间单元T3和时间单元T4，则第三时域资源包括时间单元T3和时间单元T4，感知信号未占用的传输资源为时间单元T3、时间单元T4和全部频域单元f 0、f 1、f 2……f N-1共同确定出的传输资源，如图15中有阴影填充的位置为感知信号未占用的传输资源。
在目标传输资源中传输的感知信号如图16所示，在时间单元T3、时间单元T4和全部频域单元f 0、f 1、f 2……f N-1共同确定出的传输资源块上不传输感知信号。
另一种可选的实施方式为，在确定第三时域资源时，可以将多个连续的感知信号周期作为第三时域资源，且多个连续的感知信号周期中包括通信信号中导频信号占用的第一时域资源；例如，将包括导频信号占用的第一时域资源的一个感知信号周期、包括导频信号占用的第一时域资源的感知信号周期的前一个周期、以及包括导频信号占用的第一时域资源的感知信号周期的后一个周期，作为第三时域资源。
如图13所示的目标传输资源中通信信号的资源分配方式，其中有阴影填充的位置为通信信号中导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。时域方向上T1、T2、T3、T4、T5、T6、T7、T8表示一个时间单元，频域方向上f 0、f 1、f 2……f N-1表示一个频域单元，通信信号中导频信号占用的第一时域资源为时间单元T4，通信信号中导频信号占用的频域资源为f 0、f 2；基于该种资源分配方式，感知信号未占用的传输资源包括第三时域资源和目标传输资源的全部频域资源共同确定出的传输资源块。例如，将包括导频信号占用的第一时域资源的一个感知信号周期、包括导频信号占用的第一时域资源的感知信号周期的前一个周期、以及包括导频信号占用的第一时域资源的感知信号周期的后一个周期，作为第三时域资源。
假设感知信号为如图14所示的周期信号，感知信号的一个周期为两个时间单元，感知信号周期t2包括通信信号中导频信号占用的第一时域资源，感知信号周期t2对应于时间单元T3和时间单元T4，感知信号周期t2之前的感知信号周期t1对应于时间单元T1和时间单元T2，感知信号周期t2之后的感知信号周期t3对应于时间单元T5和时间单元T6；则确定第三时域资源包括时间单元T1、T2、T3、T4、T5、T6。感知信号未占用的传输资源包括：时间单元T1、T2、T3、T4、T5、T6和全部频域单元f 0、f 1、f 2……f N-1共同确定出的传输资源块，如图17中有阴影填充的位置为感知信号未占用的传输资源。
在目标传输资源中传输的感知信号如图18所示，在时间单元T1、T2、T3、T4、T5、 T6和全部频域单元f 0、f 1、f 2……f N-1共同确定出的传输资源块上不传输感知信号。
本申请实施例在采用上述多种感知信号的资源分配方式中任一种方式，确定出感知信号的传输资源之后，在确定出的感知信号的传输资源上向第二装置发送感知信号，以及在目标传输资源上向第二装置发送通信信号。
步骤402：第一装置向第二装置发送第一指示信息；
其中，第一指示信息用于指示感知信号在目标传输资源中未占用的传输资源。
本申请实施例在确定出感知信号的传输资源后，由于感知信号不占用目标传输资源中导频信号占用的传输资源，为了使第二装置准确接收感知信号，第一装置可以将感知信号在目标传输资源中未占用的传输资源通过第一指示信息通知给第二装置；第二装置在接收感知信号时，根据感知信号在目标传输资源中未占用的传输资源，在目标传输资源中除未占用的传输资源之外的资源上接收感知信号。
由于通信信号中导频信号占用的传输资源，相比于非导频信号占用的传输资源较少，第一装置向第二装置指示的感知信号在目标传输资源中未占用的传输资源，其实质上是通信信号中导频信号占用的传输资源，由于导频信号占用的传输资源较少，第一装置向第二装置指示感知信号在目标传输资源中未占用的传输资源的方式可以降低信令开销。
或者，本申请实施例第一装置向第二装置发送第一指示信息，还可以用于指示感知信号在目标传输资源中占用的传输资源；第二装置可以直接根据第一指示信息中指示的感知信号在目标传输资源中占用的传输资源，接收感知信号。
本申请实施例第一装置在向第二装置指示感知信号在目标传输资源中未占用的传输资源时，一种可选的实施方式为，将感知信号未占用的传输资源中的时域资源和频域资源全部指示给第二装置；
例如，如图11所示的感知信号未占用的传输资源，则第一装置向第二装置发送第一指示信息中携带未占用的传输资源中的时域资源包括时间单元T1、T2、T3，以及未占用的传输资源中的频域资源包括目标传输资源的全部频域资源。
基于上述多种感知信号的资源分配方式，确定出的感知信号未占用的传输资源中的时域资源可能包括多个时间单元；在感知信号未占用的传输资源中的时域资源包括多个时间单元的情况下，第一装置在向第二装置发送的第一指示信息中可以包括未占用的传输资源的时域资源信息。
实施中，第一指示信息中携带的时域资源信息可以有以下几种表示方式：
1、时域资源信息包括感知信号未占用的传输资源中时域资源的起始时间点和结束时间点；
例如，如图17所示的感知信号未占用的传输资源，未占用的传输资源中时域资源的起始时间点为时间单元T1，未占用的传输资源中时域资源的结束时间点为时间单元T6；则第一装置在向第二装置发送的第一指示信息中包括的未占用的传输资源的时域资源信息为起始时间点时间单元T1和结束时间点时间单元T6。
2、时域资源信息包括感知信号未占用的传输资源中时域资源的长度和时域资源的起始时间点；
例如，如图17所示的感知信号未占用的传输资源，未占用的传输资源中时域资源的起始时间点为时间单元T1，未占用的传输资源中时域资源的长度为6个时间单元；则第一装置在向第二装置发送的第一指示信息中包括的未占用的传输资源的时域资源信息为起 始时间点时间单元T1和未占用的传输资源中时域资源的长度6个时间单元。
3、时域资源信息包括感知信号未占用的传输资源中时域资源的长度和时域资源的结束时间点。
例如，如图17所示的感知信号未占用的传输资源，未占用的传输资源中时域资源的结束时间点为时间单元T6，未占用的传输资源中时域资源的长度为6个时间单元；则第一装置在向第二装置发送的第一指示信息中包括的未占用的传输资源的时域资源信息为结束时间点时间单元T6和未占用的传输资源中时域资源的长度6个时间单元。
一些可能的实施方式中，第一装置为网络设备，第二装置为终端设备，则第一装置可以通过下行控制信息(Downlink Control Information，DCI)、无线资源控制(Radio Resource Control，RRC)信令、或媒体接入控制层(Medium Access Control，MAC)控制单元(Control Element，CE)等多种方式，向第二装置发送第一指示信息；
第一装置为终端设备，第二装置为网络设备，则第一装置可以通过上行控制信息(Up Control Information，UCI)等方式，向第二装置发送第一指示信息；
第一装置和第二装置均为终端设备，则第一装置可以通过串行通信接口(Serial Communication Interface，SCI)等方式，向第二装置发送第一指示信息。
本申请实施例对步骤401和步骤402执行的先后顺序不作限定，第一装置在确定出感知信号未占用的传输资源之后，可以先执行步骤401后执行步骤402，或者先执行步骤402后执行步骤401，或者同时执行步骤401和步骤402。
步骤403：第二装置根据通信信号中包括的导频信号进行信道估计；
通信信号中的导频信号是第一装置和第二装置已知的参考信号，通信信号中的导频信号和传输的有效数据经过信道传输被第二装置接收；第二装置可以根据已知的导频信号的变化，可以估计得到传输信道特性，从而恢复第一装置传输的通信信号中的有效数据。
步骤404：第二装置根据第一指示信息，获取感知信号进行目标感知；以及根据通信信号进行通信处理。
需要说明的是，本申请实施例步骤403和步骤404不区分执行的先后顺序，步骤403和步骤404也可以并行执行。
本申请实施例第二装置接收到第一指示信息后，可以获知第一装置传输感知信号未占用的传输资源，则第二装置在接收感知信号时，可以在目标传输资源中除第一指示信息指示的感知信号未占用的传输资源之外的传输资源上获取感知信号，并根据获取到的感知信号对目标进行感知。
另外，第二装置在目标传输资源上获取通信信号，第二装置根据获取到的通信信号进行通信处理；实施中，第二装置执行的通信处理可以为第一装置和第二装置之间的通信业务；例如，第一装置为终端设备，第二装置为网络设备时，通信信号可以为第一装置发起的接入请求，则第二装置在接收到通信信号后可以处理第一装置发起的接入请求。
方案二：在混合传输的通信信号和感知信号时，通信信号中的导频信号与感知信号叠加后的信号具备恒模特性。
本申请实施例提出一种通信方法，适用于图1、图2或图3所示的通信系统。参阅图19所示，该方法的具体流程可以包括：
步骤1901：第一装置生成第一通信信号和感知信号；其中，第一通信信号中的导频信号与感知信号叠加后的第一信号具备恒模特性。
本申请实施例的第一信号的恒模特性为第一信号对应的模值为恒定值，或者第一信号对应的模值在预设的范围内。
一种可选的实施方式为，在第一装置获得待发送的第二通信信号之后，对第二通信信号的导频信号进行调整，得到第一通信信号；
由于第一装置需要向第二装置在相同的传输资源上传输通信信号和感知信号，对于第二装置，接收到的是感知信号和通信信号叠加之后的信号；若第一装置直接将待发送的第二通信信号和感知信号发送给第二装置，第二装置在根据导频信号做信道估计时，使用的是第二通信信号和感知信号叠加之后的信号，第二装置接收到的导频信号由于叠加了感知信号，可能会破坏第二通信信号中导频信号的恒模特性，导致第二装置无法准确进行信道估计。而本申请实施例第一装置在向第二装置待发送的第二通信信号之前，对待发送的第二通信信号进行调整得到第一通信信号，且第一通信信号需要满足如下条件：调整后得到的第一通信信号中的导频信号与感知信号叠加后的第一信号具备恒模特性。从而基于本申请实施例第一装置在发送第二通信信号前，将第二通信信号调整为第一通信信号，这样在第一装置向第二装置在相同资源上发送第一通信信号和感知信号后，第二装置接收到的叠加了感知信号的导频信号仍然具备恒模特性，第二装置可以基于接收到的导频信号进行准确的信道估计。
本申请实施例可以采用多种不同的方式对待发送的第二通信信号进行调整，本申请实施例对第二通信信号的调整方式不作限定，只要调整后得到的第一通信信号中的导频信号与感知信号叠加后的第一信号具备恒模特性的调整方式均适用于本申请。
一种可选的实施方式为，调整后的第一通信信号中的导频信号与感知信号叠加后的第一信号，与第二通信信号中的导频信号相同。
由于第二通信信号中的导频信号为第一装置和第二装置双方约定的参考信号，第二装置根据第二通信信号中的导频信号可以准确的进行信道估计，且第二通信信号中的导频信号也具有很好的恒模特性；因此，第一装置在对待发送的第二通信信号进行调整得到第一通信信号之后，第一装置在发送第一通信信号和感知信号过程中，第一通信信号中的导频信号和感知信号叠加，第二装置接收到导频信号为第一通信信号中的导频信号和感知信号叠加之后的第一信号，由于第一信号与第二通信信号中的导频信号相同，因此第二装置可以基于获取到的导频信号进行准确信道估计。
例如，待发送的第二通信信号为s1，感知信号为s2；第一装置在相同传输资源发送第二通信信号和感知信号时，为第二通信信号分配功率系数为
Figure PCTCN2022125477-appb-000001
为感知信号分配功率系数为
Figure PCTCN2022125477-appb-000002
则第二通信信号和感知信号叠加之后，第二装置接收到的信号
Figure PCTCN2022125477-appb-000003
第一装置在发送第二通信信号之前，将第二通信信号调整为第一通信信号s3，
Figure PCTCN2022125477-appb-000004
将第一通信信号和感知信号在相同传输资源上发送，第二装置接收到的信号
Figure PCTCN2022125477-appb-000005
步骤1902：第一装置在目标传输资源上向第二装置发送第一通信信号和感知信号；
其中，目标传输资源包括时域资源和频域资源；第一装置在相同的时域资源和频域资源上发送第一通信信号和感知信号，第一通信信号占用的传输资源和感知信号占用的传输资源相同。
步骤1903：第二装置根据接收到的导频信号进行信道估计；
本申请实施例步骤1903第二装置进行信道估计的方式，可以参见上文步骤403中的介绍，在此不再详细赘述。
步骤1904：第二装置根据通信信号进行通信处理，以及根据感知信号进行目标感知。
其中，第二装置进行通信处理和目标感知的方式可以参见上文步骤404中的介绍，在此不再详细赘述。
另外，若本申请实施例调整后的第一通信信号中的导频信号与感知信号叠加之后的第一信号，与第二通信信号中的导频信号不同，第一装置还需要向第二装置发送第二指示信息，第二指示信息用于指示对待发送的第二通信信号的导频信号进行调整的调整方式。
其中，第二指示信息可以为生成导频信号所用的初始化种子表达式对应的偏移值；生成导频信号所用的初始化种子为生成导频信号时寄存器的初始化数值，初始化种子表达式为生成导频信号时寄存器的初始化数值组成的表达式。由于第二通信信号中的导频信号为第一装置和第二装置双方约定的参考信号，生成导频信号所用的初始化种子表达式也是第一装置和第二装置预先约定的，在第一装置对导频信号进行调整后，需要将初始化种子表达式对应的偏移值通知第二装置，第二装置根据接收到的初始化种子表达式对应的偏移值确定调整后的导频信号。
或者，第二指示信息还可以为生成导频信号所用的初始化种子表达式的标识信息；生成导频信号所用的初始化种子为生成导频信号时寄存器的初始化数值，初始化种子表达式为生成导频信号时寄存器的初始化数值组成的表达式。示例性的，第二指示信息可以为生成导频信号所用的初始化种子表达式的序号。第一装置可以基于多个初始化种子表达式中的一个初始化种子表达式生成导频信号，每个初始化种子表达式对应不同的标识信息，且生成导频信号所用的初始化种子表达式是与第二装置预先约定的；若第一装置对待发送的第二通信信号的导频信号进行调整，则需要将调整后生成导频信号所用的初始化种子表达式的标识信息通知第二装置，第二装置根据接收到的初始化种子表达式的标识信息确定调整后的导频信号。
由于第二通信信号中的导频信号为第一装置和第二装置双方约定的参考信号，若第一装置对第二通信信号中的导频信号进行调整，并将调整后的第一通信信号和感知信号叠加发送给第二装置，则第二装置接收到的是第一通信信号的导频信号和感知信号叠加之后的第一信号，且第一信号与第二通信信号中的导频信号不同，若第二装置还使用第二通信信号中的导频信号进行信道估计，会导致信道估计不准确。因此，本申请实施例在调整后的第一通信信号中的导频信号与感知信号叠加之后的第一信号，与第二通信信号中的导频信号不同的情况下，为了使得第二装置准确进行信道估计，需要将对第二通信信号的导频信号的调整方式通知第二装置。
一些可能的实施方式中，为了降低第一装置向第二装置发送第二指示信息的信令开销，本申请实施例第一装置和第二装置预先约定多种对待发送的第二通信信号中的导频信号进行调整的方式，在第一装置对待发送的第二通信信号中的导频信号调整之后，将采用的调整方式通过第二指示信息通知第二装置。示例性的，第二指示信息包括索引(其中，该索引可以为生成导频序列的初始化种子表达式序列的序号，或者是其它第一装置与第二装置预先约定的信息)，该索引与调整方式有对应关系，第一装置和第二装置预先存储该对应关系，第二装置接收第二指示信息后，根据该索引和对应关系确定调整方式。
例如，假设待发送的第二通信信号中的导频信号为A，感知信号为B；第一装置和第 二装置预先约定三种不同的对待发送的第二通信信号中的导频信号进行调整的方式：调整方式1、调整后的第一通信信号中的导频信号为C1，调整方式1对应的索引为0；调整方式2、调整后的第一通信信号中的导频信号为C2，调整方式2对应的索引为1；方式3、调整后的第一通信信号中的导频信号为C3，调整方式3对应的索引为2。若第一装置将待发送的第二通信信号中的导频信号调整为C1，则第一装置向第二装置发送的第二指示信息中包括索引“0”，第二装置基于第二指示信息中包括的索引“0”，确定调整后的第一通信信号中的导频信号为C1，则第二装置根据调整后的导频信号C1和感知信号B叠加之后的第一信号进行信道估计。
一些可能的实施方式中，若第一装置为网络设备，第二装置为终端设备，则第一装置可以通过DCI、RRC信令、或MAC CE等多种方式，向第二装置发送第二指示信息；若第一装置为终端设备，第二装置为网络设备，则第一装置可以通过UCI等方式，向第二装置发送第二指示信息；若第一装置和第二装置均为终端设备，则第一装置可以通过SCI等方式，向第二装置发送第二指示信息。
本申请实施例在第一装置在目标传输资源上向第二装置发送通信信号和感知信号时，可以基于上述两种方案中的任一种实现第一装置和第二装置之间的通信信号和感知信号的传输。实施过程中，第一装置还可以通知第二装置采用的传输方案；若第一装置基于方案一传输通信信号和感知信号，第一装置还需要将感知信号未占用的传输资源通知第二装置。
本申请实施例第一装置可以通过向第二装置发送第三指示信息的方式，通知采用的传输方案，以及在采用第一种传输方案时感知信号未占用的传输资源。
第一装置可以在第三指示信息中携带时域资源信息，通过时域资源信息指示在采用第一种传输方案时感知信号未占用的传输资源；其中，时域资源信息可以包括感知信号未占用的传输资源中时域资源的起始时间点和结束时间点，或者时域资源信息可以包括感知信号未占用的传输资源中时域资源的起始时间点和时域资源长度，或者时域资源信息可以包括感知信号未占用的传输资源中时域资源的结束时间点和时域资源长度。
下面介绍下不同时域资源信息分别对应的第三指示信息的格式。
1、时域资源信息包括感知信号未占用的传输资源中时域资源的起始时间点和结束时间点；
例如，第三指示信息的格式可以如表1所示：
表1：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta Tb
字长 1bit 1bit 2bit 2bit
其中：传输方案包括方案一和方案二；若第一装置采用上述方案一传输通信信号和感知信号，则传输方案对应的取值为1，若第一装置采用上述方案二传输通信信号和感知信号，则传输方案对应的取值为0。或者，第三指示信息中的传输方案对应的取值可以为缺省状态；例如，第一装置和第二装置预先约定采用方案1或方案2时，则此时第三指示信息中的传输方案对应的取值可以缺省。
若传输方案的取值为1，则需要进一步确定资源占用方式的取值；资源占用方式包括：感知信号未占用的传输资源为目标传输资源中除导频信号占用的传输资源之外的全部传输资源(上述感知信号的资源分配方式1)、感知信号未占用的传输资源为目标传输资源中 除导频信号占用的传输资源之外的部分传输资源(上述感知信号的资源分配方式2、上述感知信号的资源分配方式3和上述感知信号的资源分配方式4中任一种)。若资源占用方式为上述感知信号的资源分配方式1，则资源占用方式对应的取值为0，若资源占用方式为上述感知信号的资源分配方式2、感知信号的资源分配方式3和感知信号的资源分配方式4中任一种，则资源占用方式对应的取值为1。
若资源占用方式对应的取值为1，则表示第一装置在一定时长内的目标传输资源中的全部频域资源上不发送感知信号，则需要将感知信号未占用的传输资源中的时域范围通知第二装置，则Ta表示感知信号未占用的传输资源中时域资源的起始时间点，Tb表示感知信号未占用的传输资源中时域资源的结束时间点。
Ta的取值包括00、01、10、11。Ta取值00，表示起始时间点为导频信号占用的第一时域资源的开始时间(例如，导频信号占用的第一时域资源为一个OFDM符号，则起始时间点为导频信号占用的OFDM符号)。Ta取值01，表示起始时间点为与导频信号占用的第一时域资源相邻、且位于第一时域资源之前的第二时域资源的开始时间(例如，导频信号占用的第一时域资源为一个OFDM符号，且第二时域资源包括一个OFDM符号，则起始时间点为导频信号占用的OFDM符号之前的一个OFDM符号)。Ta取值10，表示起始时间点为包括导频信号占用的第一时域资源的一个感知信号周期的开始时间。Ta取值11，表示起始时间点为包括导频信号占用的第一时域资源的感知信号周期的前P个感知信号周期的开始时间，P大于或等于1。
Tb的取值包括00、01、10、11。Tb取值00，表示结束时间点为导频信号占用的第一时域资源的结束时间(例如，导频信号占用的第一时域资源为一个OFDM符号，则结束时间点为导频信号占用的OFDM符号)。Tb取值01，表示结束时间点为与导频信号占用的第一时域资源相邻、且位于第一时域资源之后的第二时域资源的结束时间(例如，导频信号占用的第一时域资源为一个OFDM符号，且第二时域资源包括一个OFDM符号，则结束时间点为导频信号占用的OFDM符号之后的一个OFDM符号)。Tb取值10，表示结束时间点为包括导频信号占用的第一时域资源的一个感知信号周期的结束时间。Tb取值11，表示结束时间点为包括导频信号占用的第一时域资源的感知信号周期的后Q个感知信号周期的结束时间，Q大于或等于1。
由于第三指示信息中携带的Ta的取值表示的是起始时间点与导频信号占用的第一时域资源之间的位置关系，第三指示信息中携带的Tb的取值表示的是结束时间点与导频信号占用的第一时域资源之间的位置关系；一些可能的实施方式中，第一装置通过目标传输资源向第二装置发送通信信号，导频信号在通信信号中的位置是第一装置和第二装置已知的，因此，第二装置在接收到第三指示信息之后，可以基于第三指示信息中携带的Ta和Tb，以及导频信号在通信信号中的位置，进一步确定感知信号未占用的传输资源中时域资源的位置。
需要说明的是，由于在采用上述传输方案二传输通信信号和感知信号时(传输方案对应的取值为0)，可以在目标传输资源的所有资源上传输感知信号，因此第三指示信息中的资源占用方式字段、Ta字段和Tb字段无效，取值可以为任意值。
下面结合几个不同类型的通信信号介绍下第三指示信息的格式。
在一些可能的实施方式中，本申请实施例第一装置在采用上述传输方案一发送通信信号和感知信号时，可以基于不同的通信信号类型，选择不同的资源占用方式；例如，针对 通信信号中导频信号在频域上集中分布的信号，可以在目标传输资源中的全部频域资源上不发送感知信号(即采用上述感知信号的资源分配方式2、上述感知信号的资源分配方式3和上述感知信号的资源分配方式4中任一种)。又例如，针对通信信号中导频信号在频域上稀疏分布的信号，可以在目标传输资源中的导频信号占用的频域资源上不发送感知信号(即采用上述感知信号的资源分配方式1)。又例如，针对通信信号中导频信号集中较长时间分布的信号，可以在目标传输资源中导频信号所在的第一时域资源以及第一时域资源前后一定长度的时域资源上不发送感知信号(即采用上述感知信号的资源分配方式3或资源分配方式4)。
例如，通信信号为导频信号在频域上集中分布的解调参考信号(Demodulation Reference Signal，DMRS)或信道状态信息(Channel State Information，CSI)信号。目标传输资源中通信信号的资源分配方式如图20所示，其中，时域资源包括的时间单元为一个OFDM符号，频域资源包括的频域单元为一个子载波，有阴影填充的位置为导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。感知信号为周期信号，且感知信号的周期为2个OFDM符号。
若第一装置可以采用上述感知信号的资源分配方式2，感知信号不占用导频信号占用的第一时域资源和目标传输资源的全部频域资源共同确定出的传输资源块，在目标传输资源中传输的感知信号如图20所示，在第三个OFDM符号与全部频域单元f 0、f 1、f 2……f N-1确定出的传输资源块上不传输感知信号。
第一装置向第二装置发送第三指示信息的格式可以如表2所示：
表2：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta Tb
取值 1 1 00 00
又例如，通信信号为导频信号在频域上稀疏分布的相位跟踪参考信号(Phase-tracking reference signals，PTRS)。目标传输资源中通信信号的资源分配方式如图21所示，其中，时域资源包括的时间单元为一个OFDM符号，频域资源包括的频域单元为一个子载波，有阴影填充的位置为导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。
感知信号为周期信号，若第一装置可以采用上述感知信号的资源分配方式1，感知信号不占用导频信号占用的传输资源，在目标传输资源中传输的感知信号如图21所示，在通信信号的导频信号占用的传输资源块上不传输感知信号。
第一装置向第二装置发送第三指示信息的格式可以如表3所示：
表3：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta Tb
取值 1 0 00 00
或者，第一装置对通信信号中的导频信号进行调整，使得调整后的导频信号与感知信号叠加后的信号、与调整前的导频信号相同；则，第一装置向第二装置发送第三指示信息的格式可以如表4所示：
表4：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta Tb
取值 0 0 0 0
需要说明的是，在Ta和Tb的取值为0时，可以认为该位置上的数值无效。由于在传 输方案为0是，表示采用的是对通信信号中的导频进行调整的方案，感知信号可以在全部的目标传输资源传输。
又例如，通信信号为导频信号集中较长时间分布的同步信号和物理广播信道块(Synchronization Signal and Physical Broadcast Channel Block，SSB)。目标传输资源中通信信号的资源分配方式如图22所示，其中，时域资源包括的时间单元为一个OFDM符号，频域资源包括的频域单元为一个子载波，有阴影填充的位置为导频信号占用的传输资源，其它位置为非导频信号占用的传输资源。
感知信号为周期信号，若第一装置可以采用上述感知信号的资源分配方式4，感知信号不占用第三时域资源和目标传输资源的全部频域资源共同确定出的传输资源块，第三时域资源为感知信号的第二个周期、第三个周期和第四个周期，在目标传输资源中传输的感知信号如图22所示。
第一装置向第二装置发送第三指示信息的格式可以如表5所示：
表5：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta Tb
字长 1 1 10 10
或者，第一装置对通信信号中的导频信号进行调整，使得调整后的导频信号与感知信号叠加后的信号、与调整前的导频信号相同；则，第一装置向第二装置发送第三指示信息的格式可以如表4所示。
2、时域资源信息包括感知信号未占用的传输资源中时域资源的起始时间点和时域资源长度；
例如，第三指示信息的格式可以如表6所示：
表6：第三指示信息的格式
控制字 传输方案 资源占用方式 Ta ΔT
字长 1bit 1bit 2bit 2bit
其中，传输方案、资源占用方式以及Ta的取值以及所代表含义可以参见上文描述，ΔT表示时域资源长度；示例性的，时域资源长度可以为时间单元的个数。ΔT的取值包括00、01、10、11。ΔT取值00，表示时域资源长度为0，则感知信号未占用的传输资源中时域资源的结束时间点为导频信号占用的第一时域资源的结束时间；ΔT取值01，表示时域资源长度为1个时间单元，则感知信号未占用的传输资源中时域资源的结束时间点为导频信号占用的第一时域资源之后的一个时间单元的结束时间；ΔT取值10，表示时域资源长度为2个时间单元，则感知信号未占用的传输资源中时域资源的结束时间点为导频信号占用的第一时域资源之后的两个时间单元的结束时间；ΔT取值11，表示时域资源长度为3个时间单元，则感知信号未占用的传输资源中时域资源的结束时间点为导频信号占用的第一时域资源之后的三个时间单元的结束时间。
3、时域资源信息包括感知信号未占用的传输资源中时域资源的结束时间点和时域资源长度；
例如，第三指示信息的格式可以如表7所示：
表7：第三指示信息的格式
控制字 传输方案 资源占用方式 Tb ΔT
字长 1bit 1bit 2bit 2bit
其中，传输方案、资源占用方式以及Tb的取值以及所代表含义可以参见上文描述，ΔT表示时域资源长度；示例性的，时域资源长度可以为时间单元的个数。ΔT的取值包括00、01、10、11。ΔT取值00，表示时域资源长度为0，则感知信号未占用的传输资源中时域资源的起始时间点为导频信号占用的第一时域资源的开始时间；ΔT取值01，表示时域资源长度为1个时间单元，则感知信号未占用的传输资源中时域资源的起始时间点为导频信号占用的第一时域资源之前的一个时间单元的开始时间；ΔT取值10，表示时域资源长度为2个时间单元，则感知信号未占用的传输资源中时域资源的起始时间点为导频信号占用的第一时域资源之前的两个时间单元的开始时间；ΔT取值11，表示时域资源长度为3个时间单元，则感知信号未占用的传输资源中时域资源的起始时间点为导频信号占用的第一时域资源之前的三个时间单元的开始时间。
