  • Radar technology was originally used for military purposes to detect targets such as aircraft, missiles, vehicles, and ships. With the development of technology and the evolution of society, radar is increasingly used in civilian scenarios. A typical application is that weather radar measures the echoes of meteorological targets such as clouds and rain to determine the location and intensity of clouds and rain for weather forecasting. Furthermore, with the vigorous development of the electronic information industry, the Internet of Things, and communication technology, radar technology has begun to enter people's daily life. In use, it greatly improves the convenience and safety of work and life. For example, automotive radar provides early warning information to vehicle drivers by measuring the distance and relative speed between vehicles, between vehicles and surrounding objects, and between vehicles and pedestrians, greatly improving the safety level of road traffic.
  • the radar transceiver stations there are many ways to classify radars. According to the positional relationship between the radar transceiver stations, they can be divided into: single-station radar and dual-station radar, as shown in the figure below.
  • single-station radar the signal transmitter and receiver are integrated and share a common antenna; the advantage is that the target echo signal and the receiver local oscillator are naturally coherent, and signal processing is relatively convenient; the disadvantage is that signal transmission and reception cannot be carried out at the same time, and only a signal waveform with a certain duty cycle can be used, which brings about a blind spot in detection and requires the use of complex algorithms to make up for it; or the signal transmission and reception are carried out at the same time, and the transmission and reception are strictly isolated, but this is difficult to do for high-power military radars.
  • the signal transmitter and receiver are located in different positions; the advantage is that signal transmission and reception can be carried out at the same time, and continuous wave waveforms can be used for detection; the disadvantage is that it is difficult to achieve the same frequency and coherence between the receiver and the transmitter, and the signal processing is relatively complex.
  • radar technology can adopt single-station radar mode or dual-station radar mode.
  • the transmitting and receiving signals share the same antenna, and the receiving signal and the transmitting signal enter different RF processing links through the circulator; in this mode, a continuous wave signal waveform can be used to achieve detection without blind spots, provided that the receiving signal and the transmitting signal need to be well isolated, usually requiring an isolation of about 100dB to eliminate the flooding of the receiving signal by the leakage of the transmitting signal. Since the receiver of the single-station radar has all the information of the transmitting signal, it can process the signal through matched filtering (pulse compression) to obtain a higher signal processing gain.

为使本领域技术人员能够更好地理解本申请实施例，先进行如下说明。
一、通信感知一体化或通感一体化。
未来B5G和6G无线通信系统有望提供各种高精度的传感服务，如机器人导航的室内定位、智能家居的Wi-Fi传感和自动驾驶汽车的雷达传感。传感和通信系统通常是单独设计的，并占用不同的频段。然后，由于毫米波和大规模多输入多输出(Multiple Input Multiple Output，MIMO)技术的广泛部署，未来无线通信系统中的通信信号往往在时域和角度域都具有高分辨率，这使得利用通信信号实现高精度传感成为可能。因此，最好是联合设计传感和通信系统，使它们能够共享同一频段和硬件，以提高频率效率并降低硬件成本。这促使了对通信和感知一体化(Integrated Sensing And Communication，ISAC)的研究。ISAC将成为未来无线通信系统的一项关键技术，以支持许多重要的应用场景。例如，在未来的自动驾驶车辆网络中，自动驾驶车辆将从网络中获得大量的信息，包括超高分辨率的地图和接近实时的信息，以进行导航和避免即将到来的交通拥堵。在同样的情况下，自动驾驶车辆中的雷达传感器应该能够提供强大的、高分辨率的障碍物探测功能，分辨率在厘米量级。用于自动驾驶车辆的ISAC技术提供了使用相同硬件和频谱资源实现高数据率通信和高分辨率障碍物探测的可能。ISAC的其他应用包括基于Wi-Fi的室内定位和活动识别、无人驾驶飞机的通信和传感、扩展现实(Extended Reality，XR)、雷达和通信一体化等。每个应用都有不同的要求、限制和监管问题。ISAC已经引起了学术界和工业界巨大的研究兴趣和关注。例如，最近有越来越多的关于ISAC的学术出版物，从收发机架构设计、ISAC波形设计、联合编码设计、时-频-空信号处理，到实验性能延时、原型设计和现场测试。
ISAC通过硬件设备共用和软件定义功能的方式获得通信和感知双功能的一体化低成 本实现，特点主要有：一是架构统一且简化，二是功能可重构可扩展，三是效率提升、成本降低。通信感知一体化的优势主要有三个方面：一是设备成本降低、尺寸减小，二是频谱利用率提升，三是系统性能提升。
学术界通常将ISAC的发展划分为四个阶段：共存、共运行、共设计和共同协作。
共存：通信和感知是两个相互分立的系统，两者会相互干扰，解决干扰的主要方法是：距离隔离、频段隔离、时分工作，MIMO技术、预编码等。
共运行：通信和感知共用硬件平台，利用共有信息提升共同的性能，二者之间的功率分配对系统性能影响较大，主要问题是：低信噪比、相互干扰、低吞吐率。
共设计：通信和感知成为一个完全的联合系统，包括联合信号设计、波形设计、编码设计等，前期有线性调频波形、扩频波形等，后来聚焦到正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)波形、MIMO技术等。
共同协作：多个通信感知一体化节点相互协作实现公共目标。例如，通过通信数据传输共享雷达探测信息，典型场景有驾驶辅助系统、雷达辅助通信等。
目前，根据5G通信系统架构进行技术升级而有望实现的典型通信感知一体化的场景如表1所示。
表1
二、雷达技术。
雷达(Radio Detection and Ranging，Radar)，意思是“无线电探测和测距”，即通过发射无线电波并接收目标反射回波的方式发现目标并测定目标距离。随着雷达技术的发展，雷达探测目标不仅是测量目标的距离，还包括测量目标的速度、方位角、俯仰角，以及从以上信息中提取出更多有关目标的信息，包括目标的尺寸和形状等。
雷达技术最初用于军事用途，用来探测飞机、导弹、车辆、舰艇等目标。随着技术的发展和社会的演进，雷达越来越多用于民用场景，典型应用是气象雷达通过测量云雨等气象目标的回波来测定关于云雨的位置、强度等信息用来进行天气的预报。进一步地，随着电子信息产业、物联网、通信技术等的蓬勃发展，雷达技术开始进入到人们的日常生活应 用中，大大提高了工作和生活的便利性、安全性等。例如，汽车雷达通过测量车辆之间、车辆与周边环境物之间、车辆与行人之间等的距离和相对速度对车辆的驾驶提供预警信息，极大地提高了道路交通的安全水平。
在技术层面上，雷达有很多分类方式。按照雷达收发站点之间的位置关系可以分为：单站雷达和双站雷达，如下图所示。对于单站雷达，信号发射机与接收机一体、共用天线；优点是目标回波信号与接收机本振之间天然是相干的、信号处理较为方便；缺点是信号收发不能同时进行，只能采用具有一定占空比的信号波形，从而带来探测的盲区，需要采用复杂的算法来弥补；或者收发信号同时进行，收发之间严格隔离，但是对于大功率的军用雷达来说很难做到。对于双站雷达，信号发射机与接收机位于不同的位置；优点是信号收发能够同时进行，可以采用连续波波形进行探测；缺点是接收机与发射机之间很难实现同频和相干，信号处理较为复杂。
在通感一体化无线感知应用中，雷达技术可以采用单站雷达模式，也可以采用双站雷达模式。
在单站雷达模式下，收发信号共用天线，接收信号与发射信号通过环形器进入不同的射频处理链路；在这种模式下，可以采用连续波信号波形实现无盲区的探测，前提是接收信号与发射信号需要很好的隔离，通常需要100dB左右的隔离度，以消除发射信号泄露对接收信号的淹没。由于单站雷达的接收机具有发射信号的全部信息，从而可以通过匹配滤波(脉冲压缩)的方式进行信号处理，获得较高的信号处理增益。
在双站雷达模式下，不存在收发信号的隔离问题，极大地简化的硬件的复杂度。由于雷达信号处理建立在已知信息的基础上，在5G NR通感一体化应用中，可以利用同步信号(主同步信号(Primary Synchronisation Signal，PSS)/辅同步信号(Secondary Synchronisation Signal，SSS))、参考信号(解调参考信号(Demodulation Reference Signal，DMRS)/信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)等)等已知信息进行雷达信号处理。但是，由于同步信号、参考信号等的周期性，信号波形的模糊图不再是图钉形，而是钉板形，时延和多普勒的模糊程度会增大、且主瓣的增益相较单站雷达模式降低了许多，降低了距离和速度的测量范围。通过恰当的参数集设计，距离和速度的测量范围能够满足汽车、行人等常见目标的测量需求。此外，双站雷达的测量精度与收发站点相对目标的位置有关，需要选择合适的收发站点对来提高探测性能。
三、传统的均匀分布感知信号。
考察在给定感知需求的条件下，感知信号的资源配置的需求。
感知需求包括对于目标参数的分辨率和/或最大不模糊测量范围的要求。目标参数包括：时延或距离、多普勒或速度、角度。
资源为与目标参数对应的目标域上的资源。目标域和目标域上的资源包括：
1、时域：时间资源，包括：正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号、时隙、子帧、帧等；
2、频域：频率资源，包括：子载波，资源块(Resource Block，RB)等；
3、空域：天线或端口资源。
感知需求对资源配置的需求主要包括两个方面：
1、资源的跨度：在目标域上，一个感知帧的资源从最小资源单元索引到最大资源单元索引之间的跨度，包括：时间长度(时域)、带宽(频域)、孔径(空间维度)；
2、资源单元间隔：在目标域上，一个感知帧之内在目标域上相邻的目标资源单元之间的间隔，包括：分配给感知信号的OFDM符号之间的间隔(时域)、分配给感知信号的子载波之间的间隔(频域)、分配给感知信号的天线或端口之间的间隔(空域)。
资源配置对感知的影响包括：
1、资源的跨度决定目标参数的分辨率，包括：时域上的时间跨度决定了多普勒或者速度的测量分辨率、频域上的带宽决定了时延或距离的测量分辨率、空域上的孔径决定了角度的测量分辨率；
2、目标资源单元间隔决定了目标参数的最大不模糊测量范围，包括：时域上分配给感知信号的OFDM符号之间的间隔决定了多普勒或速度的最大不模糊测量范围、频域上分配给感知信号的子载波之间的间隔决定了时延或距离的最大不模糊测量范围、空域上分配给感知信号的天线或端口之间的间隔决定了角度的最大不模糊测量范围。
下面以时域和频域的资源配置为重点讨论感知信号的资源配置与感知需求之间的关系。
1、时延/距离；
通过电磁波进行感知时直接得到的是时延信息，距离是由时延换算得到的，因此这里主要讨论时延与感知信号的资源配置之间的关系。
时延的分辨率由下式给出：
其中，B表示信号带宽。
时延的最大不模糊测量范围由下式给出：
其中，Δf为分配给感知信号的相邻子载波之间的间隔。
2、多普勒/速度
通过电磁波进行感知时直接得到的是多普勒信息，速度是由多普勒换算得到的，因此这里主要讨论多普勒与感知信号的资源配置之间的关系。
多普勒的分辨率由下式给出：
其中，T为一个感知帧的时间长度。
多普勒的最大不模糊测量范围由下式给出：
其中，Δt表示分配给感知信号的相邻OFDM符号之间的间隔。
根据上述分析，当给定感知需求中的时延和多普勒的分辨率和最大不模糊测量范围，即给定Δτ、τmax、Δfd和fd,max之后，需要的感知资源的数量为：
1、子载波的数量
OFDM符号的数量
下面结合一个典型场景来说明感知信号对于感知资源(子载波和OFDM符号)的需求。考虑交通监测的场景：
最大不模糊测距范围为200m；
测距分辨率为0.2m；
测速范围为-180km/h～180km/h(能够检测超速行驶的车辆，包括接近和远离两个方向)；
测速分辨率为0.2m/s(能够分辨缓慢行走的行人)。
考虑载波中心频率为30GHz的毫米波频段，对应的感知资源的配置需求满足以下条件：
带宽B≥750MHz；
分配给感知信号的相邻子载波之间的间隔Δf≤1500kHz；
感知帧的时间长度T≥25ms；
分配给感知信号的相邻OFDM符号之间的间隔Δt≤50μs。
综合上述分析，在这里给出的交通监测场景下，需要的感知资源的数量为：
子载波的数量Nscs≥500；
OFDM符号的数量Nsymbol≥500。
可以看出，为了满足上述交通监测场景的感知需求，时域和频域资源的开销较大。进一步考察上述时频域资源开销在整个时频域的占比。在30GHz中心频率的情况下，考虑子载波间隔为120kHz，则OFDM符号的时间长度为8.33μs。为了满足上述的资源配置要求，需要每12个子载波中有1个子载波分配给所述的感知信号、每6个OFDM符号中有1个OFDM符号分配给所述的感知信号。在多端口感知的场景下，感知资源的开销占比则会进一步增大。
在通感一体化场景中，采用传统的均匀分布的感知信号资源配置存在以下三方面的问题：
第一，为了满足感知需求(分辨率和最大不模糊测量范围)，需要较大的感知信号的 资源开销；
第二，在通信系统中，由于存在各种通信参考信号(如：CSI-RS、DMRS、相位跟踪参考信号(Phase-Tracking Reference Signal，PTRS)等)占据了大量的时频域网格，在很多情况下无法在时频域找到连续大跨度(大带宽、大时宽)的均匀分布的时频域资源网格来满足感知需求；
第三，如何结合现有的各种通信参考信号进行感知，以降低感知信号的时频域资源的开销。

第一方面：在具有相同的分辨率和最大不模糊测量范围性能的前提下，本申请提出的完全非均匀信号在很多情况下能够占用更少的时域和/或频域资源，即能够节约开销；
第二方面：本申请能够充分利用为通信功能配置的参考信号、尽可能少地为感知功能配置额外的参考信号；如图4所示，资源集1、资源集2、资源集3可能是不同的参考信号，例如：资源集1是CSI-RS、资源集2是定位参考信号(Positioning Reference Signal，PRS)、资源集3是相位跟踪参考信号(Phase-Tracking Reference Signal，PTRS)或解调参考信号(Demodulation Reference Signal，DMRS)。如果由资源集1、资源集2和资源集3组成的第一信号能够满足特征1(T1或F1)～特征3(T3或F3)的条件，则无需额外配置参考信号即可实现满足感知需求的感知；或者，资源集1、资源集2和资源集3部分满足特征1～特征3，只需额外配置少量的参考信号即可实现满足感知需求的感知。

本实施例的一个示意图如图6所示，图6中在时间维度的一格表示时域的目标资源单元(例如，OFDM符号)、在频率维度的一格表示频域的目标资源单元(例如，子载波)，。应该认识到该示意图仅用于方便对于本实施例的技术方案的理解，并不代表本实施例的信号配置局限于图6中所示。
在图6中，在时域采用本申请所述的完全非均匀信号的配置。目标OFDM符号在时域非均匀分布、其位置为{0,2,6,9,14,16,21,24,26,32,35,39,44,46,53,55,60}，这里的目标OFDM符号的位置是相对于目标资源在时域的起始位置，颗粒度是OFDM符号。另一方面，在频域上采用传统的均匀分布信号的配置，在频域目标资源单元间隔为2个子载波。在图6的示例中，在时域上目标OFDM符号间隔的平均值约为3.8个OFDM符号，大于多普勒或速度的分辨率要求的目标OFDM符号间隔(2个OFDM符号)，降低了第一信号的资源开销。
在本申请的一实施例中，在频域采用本申请提出的完全非均匀信号配置方法进行第一信号的配置；而在时域根据其他配置方法进行配置，例如在时域采用传统的均匀分布的第一信号的配置。
在此种情况下，本申请所述的第一信号在频域的配置包括以下至少一项：

在图7中，在频域采用本申请所述的完全非均匀信号的配置。目标子载波在频域非均匀分布、其位置为{0,2,5,8,10,13,18,22,24,30,33,38,40,44}，这里的目标子载波的位置是相对于目标资源在频域的起始位置、颗粒度是子载波。另一方面，在时域上采用传统的均匀分布信号的配置，在时域目标OFDM符号间隔为3个OFDM符号。在图7的示例中，在频域上目标子载波间隔的平均值约为3.2个子载波间隔，大于时延或距离的分辨率要求的目标子载波间隔(2个子载波)，降低了第一信号的资源开销。
在本申请的一实施例中，同时在时域和频域采用本申请提出的完全非均匀信号配置方法进行第一信号的配置。
在此种情况下，本申请所述的第一信号的参数配置信息包括：
时域配置参数；

本实施例的一个示意图如图8所示，图8中在时间维度的一格表示时域的目标资源单元(例如，OFDM符号)、在频率维度的一格表示频域的目标资源单元(例如，子载波)。应该认识到该示意图仅用于方便对于本实施例的技术方案的理解，并不代表本实施例的信号配置局限于图中所示。
在图8中，在时域和频域采用本申请所述的完全非均匀信号的配置。在时域上，目标OFDM符号非均匀分布、其位置为{0,2,6,9,14,16,21,24,26,32,35,39,44,46,53,55,60}，这里的目标OFDM的位置的是相对于目标资源在时域的起始位置、颗粒度是OFDM符号。在频域上，目标子载波非均匀分布、其位置为{0,2,5,8,10,13,18,22,24,30,33,38,40,44}，这里的目标子载波的位置是相对于目标资源在频域的起始位置、颗粒度是子载波。在图8的示例中，在时域上目标OFDM符号间隔的平均值约为3.8个OFDM符号，大于多普勒或速度的分辨率要求的OFDM符号间隔(2个OFDM符号)；在频域上目标子载波间隔的平均值约为3.2个子载波间隔，大于时延或距离的分辨率要求的目标子载波间隔(2个子载波)，降低了第一信号的资源开销。
可选地，所述第一信号被配置为单端口或多端口；
在所述第一信号被配置为多端口的情况下，不同端口的第一信号的资源满足以下至少一项：
频分复用；
时分复用；
不同端口的第一信号在目标域上的资源图样相同，且不同端口的第一信号采用的生成序列不同；或者，不同端口的第一信号在目标域上的资源图样相同，且不同端口的第一信号采用的生成序列相同，且不同的第一信号对应的正交覆盖码不同。
本申请实施例中，第一信号可以被配置为多端口，不同端口的第一信号的图样关系可以包括以下情况：
情况1：不同端口的第一信号采用频分复用，即通过配置不同频域偏移量区分不同端口的第一信号，例如图9所示，2端口频分复用，端口1对应的第一信号频域偏移量为0个子载波，端口2对应的第一信号频域偏移量为1个子载波，端口1和端口2在频域上的资源跨度、资源分布都相同，即具有相同的感知性能；
情况2：不同端口的第一信号采用时分复用，即通过配置不同时域偏移量区分不同端口的第一信号，例如图10所示，2端口时分复用，端口1对应的第一信号时域偏移量为0个OFDM符号，端口2对应的第一信号时域偏移量为1个OFDM符号，端口1和端口2在时域上的资源跨度、时域资源分布相同，即具有相同的感知性能；
情况3：不同端口的第一信号采用频分复用和时分复用，即通过配置不同频域偏移量和时域偏移量区分不同端口的第一信号，例如图11所示，4端口频分复用和时分复用(FD2-TD2)：端口1对应的第一信号频域偏移量为0个子载波、时域偏移量为0个OFDM符号，端口2对应的第一信号频域偏移量为1个子载波、时域偏移量为0个OFDM符号，端口3对应的第一信号频域偏移量为0个子载波、时域偏移量为1个OFDM符号，端口4对应的第一信号频域偏移量为1个子载波，时域偏移量为1个OFDM符号，端口1、端口2、端口3和端口4在时域和频域上的资源跨度、资源分布都相同，即具有相同的感知性能；
情况4：不同端口的第一信号在目标域上的图样相同，即具有相同的时域或频域配置参数，但所采用的第一信号的生成序列不同，即第一信号序列的生成参数与端口序号相关；
情况5：不同端口的第一信号在目标域上的图样相同，即具有相同的时域或频域配置参数，且采用的第一信号的生成序列相同，但在映射到时域或频域资源时通过不同的正交覆盖码(Orthogonal Covering Code，OCC)区分，例如2端口第一信号映射采用频域正交覆盖码(Frequency domain orthogonal covering code，FD-OCC)时，端口1的第一信号序列为c(m)，可直接映射到某指定时间单元(例如OFDM符号)对应的频率单元(例如RE)上，端口2的第一信号序列可为c(m)*occ(m)，occ(m)为FD-OCC序列，可表示为(1,-1,1,-1…,1,-1,1,-1)，之后映射到与端口1相同的频率单元。
下面以第一信号为NR参考信号CSI-RS为例对本申请实施例的方法进行说明，当然其他参考信号例如，解调参考信号(Demodulation Reference Signal，DMRS)、相位跟踪参 考信号(Phase-Tracking Reference Signal，PTRS)、定位参考信号(Positioning Reference Signal，PRS)、同步信号块(Synchronization Signal Block，SSB)等其他参考信号或同步信号等也属于本申请的保护范围。
在本申请的第一实施例中，在时域上采用本申请所述的完全非均匀信号。至于第一信号在频域上的分布情况，这里不做限制；在一些实施例中，分配给第一信号的子载波在频域上以常规的均匀分布排列(即，梳状分布)，例如，在第一信号所在的BWP内每个RB中的第k个子载波被分配给第一信号，其中k为RB内的子载波编号。
如图12所示，在时域上采用本申请所述的完全非均匀信号。图12中所示的情况中，第一信号包括3个资源集：资源集1在时域上的重复周期是5个时隙、时隙内的第8个(从0开始编号)OFDM符号为分配给第一信号的OFDM符号，资源集2在时域上的重复周期是9个时隙、时隙内的第4和第11个(从0开始编号)OFDM符号为分配给第一信号的OFDM符号，资源集3在时域上的重复周期为15个时隙、时隙内的第8个(从0开始编号)OFDM符号为分配给第一信号的OFDM符号。
此种配置的典型场景是，例如：对于通信功能，一个时隙内的CSI-RS出现在1个OFDM符号上、CSI-RS的重复周期配置为5个时隙(即，资源集1所示的情况)，即能够满足需求；而对于某个感知场景(在这里是多普勒或者速度的测量)，多普勒或速度的最大不模糊测量范围要求CSI-RS的OFDM符号间隔不大于1个时隙时长。如果在全部时隙上采用满足感知需求的CSI-RS配置，则会带来较大的额外开销。采用本申请所述的方法，只需在通信功能所需的CSI-RS配置开销以外额外补充一部分CSI-RS配置即可，在能够满足感知需求的前提下带来的额外开销较小。
容易理解的是，本实施例所示的配置仅为一种示例。现有协议中CSI-RS并不能支持图12中示意的周期为9个时隙和15个时隙，本实施例所给出的参数仅为方便示意。
在本实施例中，用来描述满足上述特征的第一信号的参数配置信息包括以下内容：
(1)第一信号在时域上的起始位置，为第一信号在时域上占据的第一个时隙的索引，表示为其中nf为系统帧号、为一个系统帧内包含的时隙数、为一个系统帧内的时隙号；
(2)第一信号的各个资源集在时域上的起始位置，为第一信号的各个资源集在时域上的第一个时隙的索引，表示为相对于第一信号在时域上起始位置的时隙偏移，以时隙为单位表示为Toffset，可以由CSI-ResourcePeriodicityAndOffset或CSI-RS-Resource-Mobility->slotConfig配置；
或者，第一信号的配置参数中不包括至少部分资源集的起始位置，取而代之的是，通过RRC配置、或MAC CE、DCI信令、或MAC CE和DCI的组合信令来指示对应资源集的在时域上的起始；
(3)第一信号的各个资源集在时域上的重复周期，为第一信号的各个资源集之内在时域上包含有目标OFDM符号的时隙的重复周期，以时隙为单位表示为TCSI-RS，可以由 CSI-ResourcePeriodicityAndOffset或CSI-RS-Resource-Mobility->slotConfig配置；
(4)第一信号的各个资源集之内包含有目标OFDM符号的时隙之内、目标OFDM符号的索引，例如：以OFDM符号为单位表示为l0(只有一个目标OFDM符号时)、或l0和l1(有2个目标OFDM符号时，本实施例属于此种情况)，可以由CSI-ResourceMapping中的firstOFDMSymbolInTimeDomain和/或firstOFDMSymbolInTimeDomain2配置；
(5)第一信号的各个资源集在时域上的结束位置，通过RRC配置、或MAC CE、DCI信令、或MAC CE和DCI的组合信令来指示对应资源集的结束；
(6)波束标识符(Identifier，ID)：属于同一个第一信号的所有资源集应被关联到同一波束中，即所有资源集之间具有准共址(Quasi Co-Location，QCL)关系，可以由tci-StatesToAddModList进行配置，可以将各个资源集之间配置成QCL、或者将各个资源集与同一个其他信号(如SSB)配置成QCL；
(7)资源集列表：属于同一个第一信号的所有资源集的ID的列表，用于通知第一信号的接收端哪些资源集属于对应的第一信号。
在本申请的第二实施例中，在频域上采用本申请所述的完全非均匀信号。至于第一信号在时域上的分布情况，这里不做限制；在一些实施例中，分配给第一信号的OFDM符号在时域上以常规的均匀分布排列(即，梳状分布)，例如，在每4个时隙中第一个时隙的第l个OFDM符号被分配给第一信号，其中l为时隙内的OFDM符号编号。
图13中所示意的情况中，第一信号包括4个资源集：资源集1在频域上的重复周期是1个RB、每个RB内第6个(从0开始编号)子载波被分配给第一信号，资源集2在频域上的重复周期是5个RB、每个RB内第3个(从0开始编号)子载波被分配给第一信号，资源集3在频域上的重复周期是7个RB、每个RB内第9个(从0开始编号)子载波被分配给第一信号，资源集4在频域上的重复周期是9个RB、每个RB内第3个(从0开始编号)子载波被分配给第一信号.
此种配置的典型场景是，对于某个感知场景(在这里是时延或者距离的测量)，需要目标子载波在频域上较为密度地分布，例如，如果采用传统的均匀分布(梳状分布)需要每个RB有3个子载波被分配给第一信号。然而，可能对于通信通能来说，CSI-RS在每个RB有1个子载波即能够满足通信功能的要求，即示意图13中资源集1的情况。通过本申请的配置方法，新增少量的子载波配置给第一信号，即可满足感知功能的需求，同时不额外新增过多的资源开销。
容易理解的是，本实施例所示的配置仅为一种示例。现有协议中并不能支持CSI-RS的频域周期为5个RB、7个RB和9个RB，本实施例所给出的参数仅为方便示意。
本实施例所述第一信号的参数配置信息，考虑以下配置方法，用来描述满足上述特征的第一信号的参数配置信息包括以下内容至少之一：
(1)第一信号在频域上的起始位置，为第一信号在频域上占据的最小索引的RB，可以用CSI-frequencyOccupation->startingRB进行配置，startingRB为起始RB；
(2)第一信号的各个资源集在频域上的起始位置，为第一信号的各个资源集在频域上的最小索引的RB，可以由CSI-frequencyOccupation->startingRB进行配置；
(3)第一信号的各个资源集之内目标子载波在频域上的密度，即1个RB中目标子载波的数量，可以由CSI-RS-ResourceMapping->density进行配置；
(4)第一信号的各个资源集之内目标子载波在所在的RB中的位置，可以由CSI-RS-ResourceMapping->frequencyDomainAllocation进行配置；
(5)第一信号的各个资源集在频域占用的带宽，CSI-frequencyOccupation->nrofRBs进行配置，nrofRBs为RB数；
(6)波束ID：属于同一个第一信号的所有资源集应被关联到同一波束中，即所有资源集之间具有QCL关系，可以由tci-StatesToAddModList进行配置，可以将各个资源集之间配置成QCL、或者将各个资源集与同一个其他信号(如SSB)配置成QCL；
(7)资源集列表：属于同一个第一信号的所有资源集的ID的列表，用于通知第一信号的接收端哪些资源集属于对应的第一信号。
在本申请的第三实施例中，在时域和频域都采用本申请的完全非均匀信号，如果第一信号在时域包括M个资源集、在频域包括N个资源集，则第一信号一共包括M*N个资源集。每个资源集在时域的配置参数同第二实施例、在频域的配置参数同第一实施例。
本申请实施例的上述方案，能够非常便捷地结合现有的参考信号来实现第一信号的资源配置，显著降低了第一信号的时域资源的开销。

本申请实施例的方法，能够在满足感知的分辨率性能和最大不模糊测量范围性能的前提下，大大降低感知信号的资源开销，同时，本申请实施例的方法能够方便地结合现有参考信号来实现感知信号的配置，进一步降低了资源开销。
