基于网络辅助全双工无蜂窝系统的通感一体化协议设计
Integrated Sensing and Communication Protocol Design for Network-Assisted Full-Duplex Cell-free Systems
摘要
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.关键词
