Abstract: The present invention relates to a method and apparatus for constructing a control channel and transceiving data in a wireless communication system. User equipment monitors physical downlink control channel (PDCCH) candidates which are CRC-scrambled by a cell-radio network temporary identifier in a common search space and in a user equipment-specific search space. The user equipment regards that only the desired PDCCH is transmitted in the common search space if the PDCCH candidates have a common payload size and same index of first control channel elements, thus overcoming problems of ambiguity in detection of DCI.

Abstract: The present invention proposes a method of generating a downlink frame including a primary synchronization signal and secondary synchronization signals with which interference between sectors can be reduced so as to improve the performance for searching cells. The method comprises the steps of generating a first short sequence and a second short sequence, generating a first scrambling sequence and a second scrambling sequence by the primary synchronization signal, generating a third scrambling sequence determined by a short sequence group to which the first short sequence is assigned and a fourth scrambling sequence determined by a short sequence group to which the second short sequence is assigned, scrambling the first short sequence with the first scrambling sequence and scrambling the second short sequence with the second scrambling sequence and the third scrambling sequence, scrambling the second short sequence with the first scrambling sequence and scrambling the first short sequence with the second scrambling sequence and the fourth scrambling sequence, and mapping the secondary synchronization signal that including the scambled short sequences and the fourth to a frequency domain.

Abstract: The present invention relates to a method of searching for a cell by a mobile station in a wireless communication system, wherein the wireless communication system uses a plurality of short sequences grouped into a plurality of short sequence groups, the method comprising: receiving a downlink frame including a primary synchronization signal and a secondary synchronization signal, wherein the secondary synchronization signal contains cell identity group information and the primary synchronization signal contains cell identity information within a cell identity group; and searching for a cell using the cell identity group information in the secondary synchronization signal and the cell identity information in the primary synchronization signal, wherein the secondary synchronization signal comprises a first short sequence and a second short sequence, the first short sequence is scrambled with a first scrambling sequence, and the second short sequence is scrambled with a second scrambling sequence, wherein the first scrambling sequence is determined based on the cell identity information contained in the primary synchronization signal, and the second scrambling sequence is determined based on a short sequence group to which the first short sequence is assigned, the short sequence group being determined based on a remainder of dividing an index of the first short sequence by 8.
