A method for transmitting reference signals and signals uplink to a receiver, wherein the signals uplink include ACK / NACK signals, signals other than the ACK / NACK signals, and data signals, comprising procedure: map the reference signals in units of predetermined time domain a region of two-dimensional resources, including the region of two-dimensional resources a plurality of units of time domain and a plurality of units of frequency domain; serially multiplexing the control signals and data signals while the ACK / NACK signals are not multiplexed; mapping the multiplexed signals in the region of two-dimensional resources so that the multiplexed signals are mapped in the region of two-dimensional resources beginning from the first to the last unit time domain in the first drive frequency domain, and from the first to the last unit time domain on the second drive frequency domain, and so on, until all the multiplexed signals are mapped; mapping the ACK / NACK signals at both units adjacent time domain to units of predetermined time domain in which the reference signals are mapped in the ACK / NACK signals overwrites a part of the multiplexed signals; and transmit reference signals and link signals mapped rise in the region of two-dimensional resources to the recipient; wherein said transmission comprises: performing a discrete Fourier transform, DFT, for link signals mapped rise in the region of two-dimensional and recovered in the region of two-dimensional resources in a unit of each unit domain resources time region bidimensional resources in accordance with each index of the plurality of units of frequency domain; perform an inverse fast Fourier IFFT signals for uplink subjected to DFT and add a cyclic prefix CP thereto; and transmitting uplink signals to the CP added as symbols of frequency-division multiple access SC-FDMA single carrier.
