This paper proposes an inter-user interference (IUI) reduction scheme applying successive interference cancellation (SIC) to expand the in-band full-duplex (IBFD)-applicable area in the dynamic-duplex cellular (DDC) system. If the received power of the IUI is stronger than that of the desired signal at the user equipment for downlink communication (DL-UE), the IUI component is firstly demodulated and decoded in the proposed scheme. Then, a replica signal of the IUI is generated. Finally, we can obtain the IUI-reduced desired signal by subtracting the replica signal of the IUI from the received signal. By applying the proposed scheme to the DDC system, the IBFD-applicable area can be expanded. The proposed scheme is evaluated by the link-level and the system-level simulations to show the IUI reduction and the IBFD-applicable area expansion performances. From the evaluation results, it is found that the IBFD-inapplicable area can reduce from 33.9% to 8.0%, namely the IBFD-applicable area can expand by 25.9%, by applying the proposed scheme to the DL-UE.
