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 generating a channel quality indicator (CQI) in a mobile communication system is presented. The method includes grouping a number of subcarriers to form at least one channel quality indicator subband for generating a channel quality indicator, and generating a channel quality indicator in each channel quality indicator subband, wherein a size of each channel quality indicator subband is dependent on a system bandwidth value and is an integer multiple of a downlink frequency resource unit size, wherein the downlink frequency resource unit size is prescribed according to the system bandwidth value.

Abstract: A method is provided for receiving a downlink signal at a downlink reception entity in a wireless communication system. Downlink control information is received by demodulating a Physical Downlink Control Channel (PDCCH) in a first resource block (RB) pair within an RB bundle by using a first Demodulation Reference Signal (DMRS). Downlink data is received by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs scheduled by the downlink control information within the RB bundle by using a second DMRS based on an assumption that a same precoder is applied to the scheduled one or more second RB pairs.

Abstract: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.

Abstract: A method of transmitting a control signal of a relay station is provided. The method includes: receiving a control signal and data from a base station in a first subframe; and transmitting an acknowledgement/negative acknowledgement (ACK/NACK) signal for the data to the base station in a second subframe, wherein a radio resource for transmitting the ACK/NACK signal is determined by a radio resource to which the control signal received in the first subframe is allocated and by a logical physical uplink control channel (PUCCH) index received by using a higher layer signal.
