Abstract
As one of the candidate technologies for 6G mobile system, integrated sensing and communication (ISAC) can support the mobile network evolving from the communication-only network to the multi-functional network. The networking based ISAC can empower the effective multi-node cooperative perception and sensing data sharing among multiple sensing nodes. In this article, we explore different properties of signals available for radar sensing and aim to combine the ISAC technology with the cellular network by optimizing the multi-dimensional resource scheduling. In the developed simulation platform, different mapping patterns of reference signals are exploited to realize the performance trade-off between communication and sensing functions. Finally, the ISAC enabled cooperative perception hardware testbed has been designed and implemented, which can decrease the positioning error by 61 percent compared to a single ISAC system.
