This invention discloses an integrated communication and sensing method for cloud access networks (CRAN) assisted by an active intelligent reflector. In the context of a CRAN, this method effectively reduces mutual interference between communication and sensing systems by leveraging the centralized signal processing advantages of a multi-antenna baseband processing unit (BBU). Simultaneously, it utilizes an active intelligent reflector (Active-IRS) to assist both communication and sensing. A joint design of a multi-antenna remote radio head (RRH) and beamforming at the active intelligent reflector ensures that the reflected signal from the active intelligent reflector is aligned with the target direction. The amplifier integrated into the active intelligent reflector enhances the energy of the reflected signal to counteract the impact of multipath loss on signal strength. This method achieves the desired reflector beam while maintaining the user's signal-to-interference-plus-noise ratio (SNR).
