METHOD OF CONSTRUCTING A FRAME BY MULTIPLEXING SUBFRAMES HAVING DIFFERENT CP LENGTH

摘要

PURPOSE: A frame comprising method multiplexing a sub frame with a cyclic prefix unit with a different length is provide to efficiently utilize a wireless resource using symbols with the cyclic prefix. CONSTITUTION: One or more first sub-frames including a plurality of symbols with a cyclic prefix unit with a first length are included in a frame. One or more second sub frames including the plurality of symbols with the cyclic prefix unit with a second length is included in the frame. The number of the first sub frame and the second sub frame is determined by considering an idle time in which a valid symbol is not transmitted in the frame. The frame is comprised with a time division multiplexing method.
