摘要：
Provided is a method of transmitting channel rank information (RI) when the number of bits for transmitting the channel RI to be transmitted through a physical uplink shared channel (PUSCH) is three or more. The method includes mapping channel RI to be transmitted to a channel RI bit string of 3 bits or more, Reed-Muller coding and rate-matching the channel RI bit string using a basis sequence having a 32-bit code length, and generating modulation symbols by applying the bit sequence that has been Reed-Muller coded and rate-matched to a modulation mapper. Accordingly, the method of transmitting downlink channel RI can be employed when five or more antennas are used for downlink transmission or several carrier bands are used by carrier aggregation as specified in Third Generation Partnership Project (3GPP) long term evolution (LTE)-advanced following 3GPP LTE release 10.
