Abstract: A method of allocating control information in a wireless communication system is provided. The method includes: allocating essential control information of a first system to a first sub-frame in a frame including a plurality of sub-frames each of which comprises a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and allocating essential control information of a second system to an nth sub-frame in a fixed position from the first sub-frame (where n is an integer satisfying n>1). Accordingly, in a frame supporting heterogeneous systems, essential control information can be fixedly allocated to a specific position while maintaining the number of system switching points, at which switching occurs between the systems, to one even if a radio resource allocation amount changes between the systems, and thus the essential control information that must be received by all user equipments can be effectively provided without the increase of overhead.

Abstract: Present document is related with communication of synchronization signals between base station and terminal. The base station acquires a primary synchronization signal generated using a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence having a root index M and having a length L, and a secondary synchronization signal informing a cell group ID. And, the base station transmits the primary synchronization signal at a last symbol of a specific time domain unit to one or more terminals, and the secondary synchronization signal at a second-to-last symbol of the specific time domain unit to the one or more terminals. Here, the root index M is one among a root index set comprising m0 and m1 meeting “m0+m1=(½*L)*n” or “m0−m1=±(½*L)*n”, where ‘n’ is an integer greater than 0.
