Method for transceiving a signal in wireless communication system
A method of transmitting a signal using a prescribed frame structure in a wireless communication system is disclosed. A mobile station can transmit or receive a signal using a frame structure with a CP length corresponding to ¼ of a useful symbol. Moreover, the mobile station can transmit or receive a signal using a frame structure with a CP length corresponding to ¼ of a useful symbol.
1. A method for transceiving a signal in a wireless communication system, the method comprising:
transceiving the signal through an FDD (frequency division duplex) frame according to a frame structure,
wherein the FDD frame comprises 7 subframes that comprise 6 first type subframes and 1 second type subframe, each of the 6 first type subframes including 6 OFDMA (orthogonal frequency division multiple access) symbols and the 1 second type subframe including 7 OFDMA symbols, and
wherein a channel bandwidth of the FDD frame is set to 5 MHz, 10 MHz or 20 MHz.
2. The method of claim 1 , wherein the 1 second type subframe a fourth subframe in the FDD frame.
3. The method of claim 1 , wherein an idle time is located next to a last subframe in the FDD frame.
4. The method of claim 1 , wherein:
the FDD frame comprises a CP (cyclic prefix); and
a length of the CP is set to ¼ of a useful symbol length.
