Provided are an apparatus for supporting a plurality of wireless communication systems and an operating method of the same. The apparatus receives an integrated signal including a first wireless communication system signal and a second wireless communication system signal assigned to a certain frequency band, performs first processing on the integrated signal, performs second processing on the integrated signal, is scheduled to perform at least one of first interference cancellation (IC) process of canceling interference of the first wireless communication system signal from the integrated signal based on the signal on which first processing is performed or second IC process of canceling interference of the second wireless communication system signal from the integrated signal based on the signal on which second processing is performed, and performs at least one of the first IC process or the second IC process based on the scheduling.
