Claim:
1. A method for transmitting a downlink control channel at a base station in a wireless communication system, the method comprising; configuring a plurality of control channel elements of the downlink control channel in transmission resources; mapping the control channel elements to one or more resource blocks of a subframe based on a special subframe configuration index of the subframe; and transmitting the downlink control channel in the transmission resources, wherein the type of the subframe is a special subframe of a Time Division Duplex (TDD) system with a normal cyclic prefix, wherein, when the special subframe includes a primary synchronization signal or a secondary synchronization signal, each of the one or more resource blocks does not include the control channel elements, wherein, when the special subframe does not include the primary synchronization signal or the secondary synchronization signal and the special subframe configuration index of the subframe is wherein, when the special subframe does not include the primary synchronization signal or the secondary synchronization signal and the special subframe configuration index of the subframe is
