Abstract:
1. A method of transmitting channel rank information (RI) when a number of bits for transmitting the channel RI to be transmitted through a physical uplink shared channel (PUSCH) is three or more, the method comprising: mapping the channel RI to be transmitted to a channel RI bit string of 3 bits or more; Reed-Muller coding the channel RI bit string using a basis sequence having a 32-bit code length; and generating modulation symbols by applying the Reed-Muller coded bit sequence to a modulation mapper, wherein, when the channel RI to be transmitted is mapped to a 3-bit channel RI bit string, mapping the channel RI includes mapping the channel RI (one value of {1, 2, 3, 4, 5, 6, 7, 8}) to a bit 3-bit channel RI bit string [O wherein the Reed-Muller coding is performed by the following expression: where q
