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 and an apparatus for transmitting a reception acknowledgement for hybrid automatic repeat request (HARQ) of a user equipment (UE). The reception acknowledgement may be an ACK signal or a NACK signal for physical downlink shared channels (PDSCHs). The reception acknowledgement is transmitted on a physical uplink control channel (PUCCH), and the UE selects a resource of the PUCCH based on a number of the received physical downlink control channels. That is, the UE selects a first PUCCH resource for a number of the received PDCCHs being less than a pre-defined number, and the UE selects a second PUCCH resource for a number of the received PDCCHs being equal to or greater than the pre-defined number.

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 for receiving a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system, the method comprising: monitoring, in a common search space and one or more UE-specific search spaces on a primary component carrier, PDCCH candidates having a same radio network temporary identifier (RNTI), a same payload size and a same first control channel element (CCE) index but different set of control information fields; and receiving, in the common search space on the primary component carrier, the PDCCH if the UE is configured with a carrier indicator field.

Abstract: A method and a user equipment (UE) for transmitting control information in a wireless communication system are discussed. The method according to one embodiment includes receiving a parameter which indicates whether transmission of a hybrid automatic repeat request acknowledgement (HARQ-ACK) on a physical uplink control channel (PUCCH) and a sounding reference signal (SRS) in one subframe is configured; if the parameter is true, transmitting, in a primary component carrier (CC), the PUCCH, which coincides in a same subframe as the SRS, by using a shortened PUCCH format carrying at least one of the HARQ-ACK and a positive scheduling request (SR); and if the parameter is false, transmitting the PUCCH by using a normal PUCCH format, while not transmitting, in a secondary CC, the SRS which coincides in the same subframe as the PUCCH. The shortened PUCCH format is a shortened PUCCH format 1/1a/1b or a shortened PUCCH format 3.
