Abstract： As an important feature and key enabling technology of 6G, integrated sensing and communication (ISAC) achieves information sharing and collaborative gain for communication and awareness. This paper firstly introduces the current research status of ISAC technology, and then combs it from two aspects: academic research and standardization progress. Then, this paper deeply discusses and summarizes the integration design issues of communication technology and sensing technology in three aspects: network architecture, networking and waveform design. Finally, the development trend of ISAC technology in 6G is forecasted and the possible challenges are analyzed.
Key words : 6G；integrated sensing and communication,；waveform design
0 引言
通信感知一體化(Integrated Sensing and Communication,ISAC)是指通過空口設(shè)計,、時頻資源復(fù)用、硬件資源共享等手段,，實現(xiàn)通信和感知功能一體化設(shè)計,，獲得協(xié)同增益的技術(shù)手段。隨著新興網(wǎng)絡(luò)對6G提出端到端信息處理能力的更高要求,，通信感知一體化技術(shù)成為未來6G發(fā)展的主導(dǎo)趨勢,。為了實現(xiàn)海量數(shù)據(jù)和多維信息的高效處理，計算,、人工智能賦能的通信感知一體化技術(shù)成為了目前的研究重點,。目前，學(xué)術(shù)界及國際標(biāo)準(zhǔn)化組織都對通信感知一體化技術(shù)進(jìn)行了立項研究,，如何設(shè)計通信感知一體化的網(wǎng)絡(luò)架構(gòu)和信號波形是目前研究的重點,。本文梳理了通信感知一體化技術(shù)的發(fā)展路線，分析了通信感知一體化網(wǎng)絡(luò)架構(gòu),、組網(wǎng)方法和波形設(shè)計的問題,，展望了未來的發(fā)展趨勢和需要迎接的挑戰(zhàn)。
