RECEPTION DEVICE, TRANSMISSION DEVICE, AND WIRELESS COMMUNICATIONS METHOD |
摘要 |
Provided are a receiver, a transmitter and a radio communication method capable of using non-orthogonal multiple access while suppressing cost increase and processing delay. A mobile station 200A includes a physical channel segmentation unit 210 and data demodulating/decoding units 220. A radio resource block allocated to non-orthogonal signals is defined in a frequency domain, a time domain and a non-orthogonal multiplex domain. The non-orthogonal multiplex domain has multiple levels corresponding to the number of interference cancellations by the data demodulating/decoding units 220. Interference canceller of the mobile station 200A cancels a non-orthogonal signal whose allocated radio resource block is at a lower level than that of the mobile station 200A. |
