The present invention belongs to the communications field, and discloses a radio signal processing apparatus and method, and a terminal. The apparatus includes: an acquiring module, configured to acquire at least one radio signal received by an antenna of a wireless communications system thereof, a preprocessing module, configured to determine whether a radio signal that is being currently processed carries a data packet that needs to be processed, an information processing module, configured to extract communication information carried in a radio signal that carries the data packet that needs to be processed, and an energy collection module, configured to collect energy of a radio signal that does not carry the data packet that needs to be processed. In the present invention, the preprocessing module determines whether a radio signal that is being currently processed carries a data packet that needs to be processed, and the radio signal that is being currently processed is allocated to the information proces
