Abstract
Integrated sensing and communications (ISAC) is one of the core innovations and important application scenarios of future wireless communication systems toward 5G-Advanced (5G-A) and 6G. This article summarizes the development status and analyzes the development trends from two perspectives: industry and academia. Then, this article analyzes the method to integrate sensing and communications and explains the intrinsic mechanism of ISAC. Next, the key technologies of ISAC are introduced. Among them, this article focuses on the analysis of novel waveforms of ISAC, such as orthogonal time frequency space (OTFS) and Affine Frequency Division Multiplexing (AFDM). Finally, prospect and conclusions are given.
