    摘要: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.

    摘要: A wireless communication system is disclosed. A method for performing a radio access in the wireless communication system includes dividing an available frequency band into a plurality of subbands, generating a plurality of frequency domain sequences from a plurality of data symbol sequences by independently performing a Fourier transform process in each of the subbands, independently mapping each of the frequency domain sequences to a corresponding subband, generating one or more transmission symbols by performing an inverse Fourier transform process on the plurality of frequency domain sequences mapped to the available frequency band, and transmitting the one or more transmission symbols to a receiver.
