  In this paper, we develop a framework for an innovative perceptive mobile
(i.e. cellular) network that integrates sensing with communication, and
supports new applications widely in transportation, surveillance and
environmental sensing. Three types of sensing methods implemented in the
base-stations are proposed, using either uplink or downlink multiuser
communication signals. The required changes to system hardware and major
technical challenges are briefly discussed. We also demonstrate the feasibility
of estimating sensing parameters via developing a compressive sensing based
scheme and providing simulation results to validate its effectiveness.
