Reception of Non-Orthogonal Multiple Access of a Sensing and Communication Signal

Abstract

Methods and techniques are described for determining from a received wireless communication signal channel state information CSI of a communication signal and a sensing signal that are included in the wireless communication signal. The communication signal and sensing signal are multiplexed in a non-orthogonal manner. The sensing CSI is determined using the sensing signal that is known and the received wireless communication signal. Then, based on the sensing CSI, a communication signal portion of the wireless communication signal is determined. Said portion is used together with a reference signal also included in the wireless communication signal to determine the communication CSI. With the known communication CSI and communication signal portion, the communication signal is obtained. The CSI of the communication signal and sensing signal may be determined together with the communication signal in an iterative manner, enabling robust separation of communication and sensing signal within a joint communication and sensing environment.
