DEVICE AND A METHOD FOR TRANSCEIVING A SIGNAL IN A WIRELESS COMMUNICATION SYSTEM USING A FRAME STRUCTURE WITH A CP LENGTH CORRESPONDING TO 1/8 OF AN EFFECTIVE SYMBOL LENGTH IN A CHANNEL BANDWIDTH OF 7MHZ

摘要

PURPOSE: A device and a method for transceiving a signal in a wireless communication system are provided to use a frame structure with a CP length corresponding to 1/8 of an effective symbol length, thereby transceiving a signal without collision and interference with a frame structure of a different CP length.;CONSTITUTION: A device for transceiving a signal in a wireless communication system comprises a step of transceiving a signal through a frame according to a fixed frame structure. The frame comprises 5 sub frames. The 5 sub frames are made of type-1 sub frames with 6 OFDMA(Orthogonal Frequency Division Multiplexing Access) symbols and type-2 sub frames with 7 OFDMA symbols. The CP length of the frame corresponds to 1/8 of an effective symbol length.;COPYRIGHT KIPO 2011
