PROBLEM TO BE SOLVED: To provide a receiving device, a transmitting device, and a radio communication method capable of utilizing non-orthogonal multiple access while suppressing cost rise and processing delay.SOLUTION: A mobile station 200A receives non-orthogonal signals and receives a reference signal which is used for canceling interference, and extracts the non-orthogonal signal addressed to the mobile station 200A by demodulating and canceling a radio signal addressed to another mobile station from the received non-orthogonal signals. The mobile station 200A demodulates the extracted non-orthogonal signal addressed to the mobile station 200A on the basis of the reference signal. The reference signal is multiplexed into the same radio resource block as a radio resource block allocated to the non-orthogonal signal, and is multiplexed into the radio resource block only when at least one signal is scheduled for the radio resource block.SELECTED DRAWING: Figure 6 |
