通信感知一体化即在同一系统中通过频谱共享与硬件共享，实现通信、感知功能一体化设计，系统在进行信息传递的同时，能够感知方位、距离、速度等信息，对目标物体或事件进行检测、跟踪、识别，通信系统与感知系统相辅相成，实现整体性能上的提升并带来更好的服务体验。
未来移动通信系统例如超五代(Beyound 5th Generation，B5G)移动通信系统或6G系统除了具备通信能力外，还将具备感知能力。感知能力，即具备感知能力的一个或多个设备，能够通过无线信号的发送和接收，来感知目标物体的方位、距离、速度等信息，或者对目标物体、事件或环境等进行检测、跟踪、识别、成像等。未来随着毫米波、太赫兹等具备高频段大带宽能力的小基站在6G网络的部署，感知的分辨率相比厘米波将明显提升，从而使得6G网络能够提供更精细的感知服务。
通信与雷达的一体化属于典型的通信感知融合应用，在过去，雷达系统与通信系统由于研究对象与关注重点不同而被严格地区分，大部分场景下两系统被分发研究。事实上，雷达与通信系统同样作为信息发送、获取、处理和交换的典型方式，不论工作原理还是系统架构以及频段上存在着不少相似之处。通信与雷达一体化的设计具有较大的可行性，主要体现在以下几个方面：首先，通信系统与感知系统均基于电磁波理论，利用电磁波的发射和接收来完成信息的获取和传递；其次，通信系统与感知系统均具备天线、发送端、接收端、信号处理器等结构，在硬件资源上有很大重叠；随着技术的发展，两者在工作频段上也有越来越多的重合；另外，在信号调制与接收检测、波形设计等关键技术上存在相似性。通信与雷达系统融合能够带来许多优势，例如节约成本、减小尺寸、降低功耗、提升频谱效率、减小互干扰等，从而提升系统整体性能。
目前，对于雷达和通信系统的一体化设计已经有不少相关研究，典型的联合设计包括频谱共存，即两系统独立工作，可以允许信息交换以降低互相之间的干扰；收端共享，此时两系统发端发送各自的信号波形，两系统的波形需要具备正交性，从而不影响各自的接收检测；发端共享，即发送端发射雷达与通信的联合波形；以及收发端共享，即两系统收发两侧进行资源共享，同样需要使用联合波形或者存在正交关系的波形。一体化波形设计的关键在于尽量减小通信信号与感知信号间的干扰，满足通信、感知功能的需求，在保证系统性能的前提下提高频谱效率。一体化波形可以采取复用的方式，包括时分复用、频分 复用、空分复用，也可以采取共用的方式，即设计新的融合波形，设计时需要考虑一体化波形要以通信功能为主还是雷达探测功能为主，寻找性能上的平衡点。常见的融合波形主要分为单载波波形与多载波波形，单载波波形设计通常与扩频技术相结合，例如直接序列扩频(Direct-Sequence Spread Spectrum，DSSS)、啁啾扩频(Chirp Spread Spectrum，CSS)，其中Chirp信号也被称为线性调频信号(Linear Frequency Modulation，LFM)，是频率随时间线性变化的信号，常用于雷达系统，帮助改善分辨率和最大搜索范围之间的平衡，是一种常见的雷达调制信号。Chirp信号也是一种扩频信号，具有很强的抗干扰特性和鲁棒性。多载波一体化波形较典型的是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM))波形，其相对于单载波扩频一体化波形存在一定优势，例如更高的频谱效率、灵活的带宽资源分配、无距离-多普勒耦合效应等，在设计时需要根据雷达检测需求，合理设计帧结构，例如子载波间隔以及循环前缀等均会对感知功能带来影响。
在进行感知时，可以是基于单站模式的感知，即收发共址，发送端发射用于感知的信号，然后自己接收回波信号并进行分析，提取感知参数，例如，基站作为用于感知的信号的发送端与接收端，终端或其他物体作为感知目标；也可以是基于双站/多站模式的感知，即收发不共址，发送端发射用于感知的信号，其他接收端进行接收并分析，提取感知参数，例如，基站1作为用于感知的信号发送端，终端或者基站2作为用于感知的信号接收端。同样地，单站或多站模式感知的发射端也可以是终端。
通信系统需要将承载信息的调制符号与用于信道估计的导频符号联合发送，重点关注译码性能，其信道估计算法仅需估计具有有限未知参数的复合信道，通常以提高吞吐量和传输可靠性为优化目标，关注的性能指标一般是频谱效率、信道容量、信噪比((Signal to Noise Ratio，SNR)、信号与干扰加噪声比(Signal-To-Noise And Interference Ratio，SINR)、误码率(Bit Error Rate，BER)、数据块差错率(Block Error Rate，BLER)以及误符号率(Symbol Error Rate，SER)等。而感知系统信号发送过程中无需考虑信息承载问题，通常使用优化或未经调制的发射信号，重点关注感知目标对发射信号带来的改变，即响应特性，通常以提高参数估计精度为优化目标，性能衡量指标可能是模糊函数、克拉美罗下界、均方根误差、互信息、率失真函数、雷达估计速率、韦尔奇下界以及一些与感知场景和需求相关联的指标。
