In addition to the IRC receiver, we consider nonlinear interference cancellation, such as successive interference cancellation (SIC), as one key future advanced receiver technology for the future radio access. However, one issue regarding the SIC receiver for the UE terminal side is that the SIC receiver requires a condition in which interference signals to be cancelled are decodable at the UE receiver. Thus, it may be challenging to apply a SIC receiver to cancel intercell interference since those signals are typically difficult to decode. Compared to that, the application of SIC to intracell multiple access schemes can be more feasible. Initial investigations reported that intracell non-orthogonal multiple access using a SIC receiver improves spectrum efficiency and user fairness .
