【摘要】 第六代移动通信技术的研究受到了广泛关注。随着通信和雷达频率范围的重叠，学者们对通感一体化的研究产生了浓厚兴趣。然而，分布式联合感知技术目前仍面临自干扰和互干扰等物理层挑战。基于第五代新空口协议，提出了一种针对网络辅助全双工无蜂窝系统的通感一体化协议方案，增设了感知解调参考信号。这一创新旨在通过低成本的改动，实现高质量的高通感一体化性能。该方案有效地解决了无蜂窝场景中接入点之间的感知干扰问题，它使得接收机能够准确地识别信源并估计信道，从而在确保通信性能的同时，实现精确的感知功能。更多还原

【Abstract】 Research on the sixth generation of mobile communication technology has attracted widespread attention. With the overlap of communication and radar frequency ranges, scholars have developed a keen interest in integrated sensing and communication(ISAC). However, distributed joint sensing technologies still face physical layer challenges such as self-interference and mutual interference. Based on the 5G new radio protocol, a novel ISAC protocol scheme for network-assisted full-duplex cell-free systems is proposed, incorporating sensing demodulation reference signals. This innovation aims to achieve high-quality ISAC performance with low-cost modifications. The scheme effectively resolves the sensing interference between access points in cell-free scenarios. It enables the receiver to accurately identify the signal source and estimate the channel, thus ensuring communication performance while achieving precise sensing capabilities.更多还原
