    摘要: A method for multiplexing one or more multiple access regions is disclosed. The method for multiplexing one or more multiple access regions in a wireless access system comprises multiplexing the one or more multiple access regions so that a first base station and a second base station among a plurality of base stations which use one or more multiple access schemes together under a multi-cell environment use a single multiple access scheme in a predetermined resource region allocated to each of the first base station and the second base station; and transmitting multiplexing information obtained from the multiplexing the one or more multiple access regions to a mobile station included in a cell region of the plurality of base stations. As a user uses SC-FDMA scheme and OFDMA scheme together, it is possible to obtain a single carrier effect of the SC-FDMA system and flexibility of the OFDMA system on a time axis and a frequency axis.

    摘要: The present invention relates to a broadband wireless access system, and more particularly, to a frame structure to which OFDM symbols having a cyclic prefix are transmitted. A method of constructing a frame in a broadband wireless access system according to one embodiment of the present invention comprises including one or more first subframes in the frame, the first subframes including a plurality of symbols having a cyclic prefix of a first length; and including one or more second subframes in the frame, the second subframes including a plurality of symbols having a cyclic prefix of a second length different from the first length, wherein the number of the first subframes and the number of the second subframes are determined considering an idle time for which effective symbols are not included in the frame.
