Abstract
In this work, we investigate network-level integrated sensing and communication (ISAC) to strike a tradeoff between the sensing and communication (S&C) performance. Using stochastic geometry, we analyze S&C performance by deriving tractable expressions for area spectral efficiency (ASE), based on which, we optimize the cluster sizes of cooperative base stations for S&C, along with user/target numbers, to achieve a flexible S&C tradeoff. It is shown that interference cancellation significantly improves the communication and radar information rate. Interestingly, optimal communication tradeoffs aimed at maximizing ASE mainly emphasize spatial resource utilization all for both multiplexing gain and diversity gain with no interference nulling. Conversely, to maximize sensing performance, interference cancellation is generally required. Simulation results confirm that our proposed cooperative ISAC scheme significantly improves S&C performance.
