Abstract: A method for channel-coding information bits using a code generation matrix including 32 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 32-bit length corresponding to columns of the code generation matrix, and outputting the channel-coded result as an output sequence. If “A” is higher than 10, the code generation matrix is generated when (A-10) additional basis sequences were added as column-directional sequences to a first or second matrix. The first matrix is a TFCI code generation matrix composed of 32 rows and 10 columns used for TFCI coding. The second matrix is made when at least one of an inter-row location or an inter-column location of the first matrix was changed. The additional basis sequences satisfy a value 10 of a minimum Hamming distance.

Abstract: A method for transmitting channel quality information for a downlink channel. The method according to one embodiment includes receiving, by a User Equipment (UE), configuration information on periodic channel state information (CSI) reporting by higher layer signaling; and determining, by the UE, a channel quality information index at least based on a UE-specific reference signal overhead. The UE-specific reference signal overhead is determined according to a rank value. The method according to the one embodiment further includes transmitting the determined channel quality information index to a base station. The channel quality information index is determined further based on an assumption of no resource element allocated for a Channel Status Information-Reference Signal (CSI-RS).
