When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions.

摘要： A channel coding method of variable length information using block code is disclosed. 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 for implementing transmit diversity in a wireless mobile communication system adopting an SC-FDMA scheme is provided. A sequence of modulation symbols output from a DFT block are precoded prior to IFFT. The precoding is performed independently on an antenna basis. Modulation symbols mapped to each subcarrier of an SC-FDMA symbol, to be transmitted through each antenna may be additionally phase-shifted.

摘要： Signal transmitting and decoding methods considering repeatedly transmitted information in transmitting informations in various types are disclosed. Both a first type information varying with a long period and a second type information varying with a short period are simultaneously transmitted by a same period. A receiving side receiving these informations is able to perform fast decoding by unmasking the corresponding information prior to decoding of a next received signal after obtaining the first type information in a manner of considering a fact that the first type information is repeatedly transmitted for a prescribed period of time.
