A method of transmitting subframe designating information by a base station, which is transmitted to one or more user equipments via a downlink in a wireless communication system, the method comprising: generating subframe designating information for designating at least one specific type subframe within at least one radio Frequency Division Duplex, FDD, frame, a period value of the subframe designating information, and an offset value associated with a start position at which the subframe designating information is applied; and transmitting system information comprising the period value, the offset value and the subframe designating information to the one or more user equipments, wherein each of the at least one radio FDD frame includes 0 th to 9 th subframes, each of the 0 th to 9 th subframes including 2 slots and each of the 2 slots including a predetermined number of Orthogonal Frequency Division Multiplexing, OFDM, symbols, wherein the subframe designating information consists in a bitmap in which each bit of the bitmap respectively corresponds to each of a predetermined number of subframes among subframes within the at least one radio FDD frame, wherein each bit of the bitmap respectively indicates whether or not the corresponding subframe of the predetermined number of subframes is the specific type subframe, and said method characterised in that, when 0 th, 5 th or 9 th subframe among the 0 th to 9 th subframes of any one of the at least one radio FDD frames is designated as the specific type subframe by the bitmap, OFDM symbols, other than OFDM symbols used for a synchronization channel, a physical broadcast channel, a common reference signal and a physical downlink control channel, from among a plurality of OFDM symbols belonging to the designated 0 th, 5 th or 9 th subframe, are designated, by the subframe designating information, to be used for the specific type subframe. generating subframe designating information for designating at least one specific type subframe within at least one radio Frequency Division Duplex, FDD, frame, a period value of the subframe designating information, and an offset value associated with a start position at which the subframe designating information is applied; and transmitting system information comprising the period value, the offset value and the subframe designating information to the one or more user equipments, wherein each of the at least one radio FDD frame includes 0 th to 9 th subframes, each of the 0 th to 9 th subframes including 2 slots and each of the 2 slots including a predetermined number of Orthogonal Frequency Division Multiplexing, OFDM, symbols, wherein the subframe designating information consists in a bitmap in which each bit of the bitmap respectively corresponds to each of a predetermined number of subframes among subframes within the at least one radio FDD frame, wherein each bit of the bitmap respectively indicates whether or not the corresponding subframe of the predetermined number of subframes is the specific type subframe, and said method characterised in that, when 0 th, 5 th or 9 th subframe among the 0 th to 9 th subframes of any one of the at least one radio FDD frames is designated as the specific type subframe by the bitmap, OFDM symbols, other than OFDM symbols used for a synchronization channel, a physical broadcast channel, a common reference signal and a physical downlink control channel, from among a plurality of OFDM symbols belonging to the designated 0 th, 5 th or 9 th subframe, are designated, by the subframe designating information, to be used for the specific type subframe.
