Abstract: System and method for integrating sensing and communication (ISAC) systems with backscattering radio frequency identification (RFID) tags are disclosed. An access point employs a communication beam to serve a communications device while using a sensing beam to detect an RFID tag. Under the total transmit power constraint of the system, sensing and communication beams are designed by considering tag detection and communication specifications. Zero-forcing is used to design the beamforming vectors, and a convex optimization problem is solved to determine the power allocation between sensing and communication. Minimizing the total transmit power and satisfying tag detection and communication specifications are accomplished by joint beamforming design. To resolve this, we re-formulate the non-convex constraints into convex second-order cone constraints.
