Multi-Domain Cooperative SLAM: The Enabler for Integrated Sensing and Communications

Simultaneous localization and mapping (SLAM) provides user tracking environmental capabilities, enabling communication systems to gain situational awareness. Advanced networks with ultra-wideband, multiple antennas, a large number of connections present opportunities for deep integration sensing communications. First, the development integrated communications (ISAC) is reviewed in this study, differences between ISAC traditional are revealed. Then, efficient mechanisms multi-domain collaborative SLAM presented. In particular, research challenges cross-sensing, cross-user, cross-frequency, cross-device proposed. addition, SLAM-aided strategies explicitly discussed. We prove that cooperative based on hybrid crowdsourcing can considerably improve accuracy complex multipath propagation environments through numerical analysis. Furthermore, we conduct testbed experiments show proposed achieve decimeter-level practical scenarios, thereby proving application prospect ISAC.
