Joint Communication and Sensing in Future 6G Network
Wireless and radar systems share many commonalities in terms of signal processing algorithms, devices, and to a certain extent, system architecture, however, they have always been investigated as independent operations with different goals, i.e., communication and sensing. With the emergence of 5G New Radio (NR) and the upcoming 6G Systems, wireless and radar systems will also potentially share the spectrum. These have recently motivated significant research interests in the cooperation, coexistence, and joint design (or co-design) of the two systems, namely Joint Communication and Sensing (JCAS). The integration of these two systems in a single-one can achieve a reduced device size, power consumption, and cost, leading also to more efficient radio spectrum usage, and it is expected to significantly expand the capabilities and performance of both communication and radar sensing. The most challenging issue in the JCAS framework is the design of a proper waveform capable to exploit both communication and sensing capabilities according to the specific requirements of each service, (e.g., data rate, bit error rate and target resolution, detection probability). With this aim, focus of this PhD research is to derive a complete mathematical description of a new JCAS system capable to meet all the requirements in which sensing information are used to support and improve communication QoS. Moreover, suitable metrics analysis will be defined to quantify benefits, resources required and bounds for the proposed system.
