Abstract:
1. 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 radio frame period information and offset information for designating at least one radio FDD (frequency division duplexing) frame containing one or more target subframes; generating the subframe designating information for designating the one or more target subframes within the at least one radio FDD frame designated by the radio frame period information and the offset information; and transmitting system information comprising the radio frame period information, the offset information and the subframe designating information to the one or more user equipments, wherein the at least one radio FDD frame includes 0 wherein the subframe designating information has a bitmap in which each bit of the bitmap corresponds to each of a predetermined number of subframes selected from among all subframes within the at least one radio FDD frame, wherein each bit of the bitmap indicates whether or not each of the predetermined number of subframes is one of the one or more target subframes, wherein the bitmap includes 6-bit information for designating the one or more target subframes within one radio FDD frame, wherein each bit of the 6-bit information, from the leftmost bit of the 6-bit information, indicates whether 1
