RECEPTION DEVICE, TRANSMISSION DEVICE, AND WIRELESS COMMUNICATIONS METHOD

摘要

Provided are a reception device, a transmission device, and a wireless communications method that are capable of utilizing non-orthogonal multi-access while suppressing both cost increases and processing delays. A mobile station (200A) comprises a physical channel isolation unit (210) and a data demodulating/decoding unit (220). A wireless resource block allocated for non-orthogonal signals is defined by a frequency area, a time area, and a non-orthogonal multiplex area. The non-orthogonal multiplex area has a plurality of levels corresponding to the number of interference cancellations by the data demodulating/decoding unit (220). An interference canceller in the mobile station (200A) cancels non-orthogonal signals allocated to the wireless resource block which is on a level lower than the mobile station (200A).
