To suppress reduction in system performance for mobile communications (group mobility) in a plurality of terminals existing inside the same moving object, a radio communication system is for a plurality of user terminals existing inside a moving object and a radio base station, the user terminal has a reception section that receives a signal transmitted from the radio base station, and a transmission section that transmits the signal transmitted from the radio base station to a common reception apparatus disposed inside the moving object, the common reception apparatus has a received signal detecting section that detects a signal for each user terminal, based on signals transmitted from the plurality of user terminals, and a transmission section that transmits the detected signal to each user terminal, and the user terminal receives the signal for the user terminal detected in the common reception apparatus in the reception section to demodulate. By this means, for group mobility, it is possible to cancel interference among user terminals to improve the multiplexing effect, while suppressing communication overhead.
