    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 20 rows and A columns corresponding to length of the information bits includes, channel-coding the information bits having “A” length using basis sequences having 20-bit length corresponding to columns of the code generation matrix. If “A” is 10, individual basis sequences of the code generation matrix correspond to column-directional sequences of a specific matrix composed of 20 rows and 10 columns. The specific matrix is made from 20 rows of the (32,10) code matrix used for TFCI coding were selected.

    摘要: A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. 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. Here, the UE monitors a UE-specific search space, among the search spaces. The UE-specific search space is given based on a modulus operation using the variable of Yk for the subframe k and a variable C for the subframe k, wherein Yk is defined by: Yk=(A*Yk−1+B) mod D, the variable C is determined based on the number of CCEs (NCCE) divided by the aggregation level (L), and A, B and D are predetermined constant values predetermined regardless of the aggregation levels (L).
