Abstract: From 2019, 5G standards and equipment have gradually taken shape, and the trend of communication business towards industrialization and diversification has gradually become clear, thus giving birth to the research of new communication systems. 6G, as a new generation of communication system, has been expanded in depth and breadth in terms of service comprehensiveness and precision. At present, the 6G alternative technologies include THz technology, large-scale antenna, IRS and communication perception fusion. The integration of communication and perception has become the key research technology of 6G in early 2021. It can greatly reduce the redundant deployment of the system by multiplexing the communication and perception architecture and signals. This paper will analyze the research needs, architecture and technology of 6G communication perception integration, so as to comprehensively introduce the feasibility and key research direction of 6G synaesthesia integration.
Key words : sensing and communication,;6G;architecture

    6G是新一代的移動(dòng)通信系統(tǒng),,其與5G相比,,支持更高的數(shù)據(jù)速率、更低的時(shí)延和更高的可靠性,,并且更加親和用戶和業(yè)務(wù),,即可以為用戶提供針對(duì)性更強(qiáng)的高質(zhì)量服務(wù)。此外,,6G也將無線融合通信納入研究范疇,,其中通信和感知融合就是一種典型的融合通信。

    一方面,,無線移動(dòng)網(wǎng)絡(luò)覆蓋范圍廣泛,,是最大的陸地覆蓋網(wǎng)絡(luò),與雷達(dá)等感知網(wǎng)絡(luò)相比,,范圍更加廣泛,,無線通信網(wǎng)絡(luò)與雷達(dá)系統(tǒng)相結(jié)合,,可以實(shí)現(xiàn)感知范圍的極大擴(kuò)展;另一方面,,5G和6G已經(jīng)極大地在技術(shù)上提升了網(wǎng)絡(luò)的質(zhì)量,,但是仍無法滿足不斷提升的業(yè)務(wù)需求,但感知的加入可以提升無線通信性能,,實(shí)現(xiàn)網(wǎng)絡(luò)質(zhì)量的提升,。

    目前,國(guó)內(nèi)外專家已經(jīng)對(duì)通感一體化技術(shù)開展了研究,,分別從通信賦能感知,、感知促進(jìn)通信兩個(gè)角度進(jìn)行了分析。文獻(xiàn)[1]-[3]介紹了6G中通感一體化的契機(jī),、場(chǎng)景,,并分析了一些技術(shù)調(diào)整;文獻(xiàn)[4]對(duì)通感融合和定位技術(shù)的應(yīng)用場(chǎng)景,、技術(shù)和調(diào)整進(jìn)行了描述,;文獻(xiàn)[5]-[6]介紹了通感融合技術(shù)中波形選擇和新波形開發(fā)和研究;文獻(xiàn)[7]從安全的角度分析了通感融合的問題,、調(diào)整并介紹了架構(gòu)等,;文獻(xiàn)[8]通過感知位置或者障礙物,智能化調(diào)整波束賦形,,從而提高通信的效率和質(zhì)量,。

    本文首先介紹了通信和感知一體化的必然性,分別從頻率,、技術(shù)和業(yè)務(wù)需求3個(gè)方面進(jìn)行了介紹,;然后從通感一體化不同的融合程度給出了3種架構(gòu);再次,,介紹了通感融合的典型使能技術(shù),,最后對(duì)全文進(jìn)行了總結(jié)。
