Abstract: A method is provided for a User Equipment (UE) operating in a wireless communication system. The method includes monitoring a control channel candidate with a downlink control information (DCI) format size in a plurality of search spaces. Each of the plurality of search spaces corresponds to a respective carrier indicator field (CIF) value. The method further includes transmitting or receiving data using downlink control information which is detected by monitoring the control channel candidate. In a state that control channel candidates have different values of carrier indicator field for the DCI format size, the control channel candidate with the DCI format size is received in any search space corresponding to any of the different values of carrier indicator field for the DCI format size.

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.
