    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).

    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, 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.
