摘要： 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.

摘要： A method of acquiring information on a resource region for transmitting PHICH and a method of receiving PDCCH using the same are disclosed. The resource region for transmitting the PHICH can be specified by first information corresponding to the per-sub frame PHICH number and second information corresponding to a duration of the PHICH within the subframe. The first Information can be specified into a form resulting from multiplying a predetermined basic number by a specific constant. And, the specific constant can be transmitted via PBCH. Moreover, the second information can be acquired from the PBCH as well.

摘要： A method for indicating a combination between a codeword and a layer in a MIMO communication, system, a layer mapping method, and a data transmission method using the same are disclosed. A minimum number of codeword-layer mapping combinations from among all available combinations based on the’ numbers of all codewords and all layers are pre-defined in consideration of a ratio of a codeword to a layer, a reception performance of a receiver, and reduction of combinations, so that a data transmission method using the predefined combinations is implemented. If a specific one codeword is mapped to at least two layers, a diversity gain can be acquired.

摘要： A method of a user equipment (UE) operating in a wireless communication system is provided. The UE transmits a first subframe. The UE transmits a second subframe following the first subframe consecutively. When the first subframe and the second subframe are overlapped, the first subframe is transmitted completely while the second subframe is transmitted partially.

摘要： A method and apparatus are described for transmitting a channel state information (CSI) reporting at a user equipment (UE) in a wireless communication system. A rank indicator (RI) and a first type precoding matrix indicator (PMI) are transmitted to a base station (BS) according to a first CSI feedback type. A second type PMI and a channel quality information (CQI) are transmitted to the BS according to a second CSI feedback type. The RI and the first type PMI are jointly coded, and transmitted through a physical uplink control channel (PUCCH). A reporting period of the first type PMI is longer than a reporting period of the second type PMI. The first type PMI is a wideband PMI, and the second type PMI is a subband PMI. The reporting period of the first type PMI is equal to a reporting period of the RI.

摘要： A method for transmitting information of resources for use in transmission of ACK/NACK signals in a mobile communication system is disclosed. An example method for receiving ACK/NACK signals in a mobile communication system is also disclosed. When resources for transmission of data and resources for transmission of control information of the data are scheduled through virtual unit resources, the method identifies information of resources for receiving an ACK/NACK signal for transmission data mapped to information of at least one of a virtual unit resource allocated to the transmission data and a virtual unit resource allocated to control information of the transmission data, and receives the ACK/NACK signal for the transmission data through the information of resources for receiving the ACK/NACK signal.

摘要： A method for transmitting downlink control information and a method for generating a codeword for the same are disclosed. In generating a long code having a low code rate, a basic code of which minimum distance between codes is maximized is repeated by a prescribed number of times and bits of the repeated code are adjusted. Therefore, a minimum distance condition between codes of a long code is satisfied and simultaneously the code can be simply generated. Furthermore, control information can be transmitted with a low error rate by using the generated code.
