The transfer of; (Physical Uplink Shared Channel PUSCH) channel rank information is started through the uplink shared channel if the number of bits for transmitting; (Rank Information RI) greater than 3 bit channel rank information. Channel rank information transmission method according to the invention by the step, channel rank information bit sequence for mapping the channel rank information is to be sent to the column 3 bits or more channel rank information bits using a basis sequence (basis sequence) of the 32-bit code length Reed-Muller coding (Reed-Muller coding) and rate matching (rate matching) for phase and Reed-Muller coding and rate-matched bit sequence to modulation mapper (modulation mapper) to apply to modulation symbols of generation to step includes configuring It can be. Therefore, when using multiple carrier band downlink channel rank information transmission method according to the invention by a case of applying more than four antennas in the downlink transmission and the carrier aggregation, such as LTE-advanced in the 3GPP LTE release 10 after the to be applied.
