Method of configuring cyclic prefix for small cell in wireless communication system and apparatus therefor
Disclosed herein is a method of transceiving a signal between a transmitter and a receiver in a wireless communication system. The method includes transceiving the signal in units of a subframe including a plurality of symbols. Each of the plurality of symbols includes a valid symbol and a cyclic prefix, and a length of the cyclic prefix is changed according to a distance between the transmitter and the receiver.
1. A method of transceiving a signal between a transmitter and a receiver in a wireless communication system, the method comprising:
transceiving the signal in units of a subframe including a plurality of symbols,
wherein each of the plurality of symbols consists of a valid symbol and a cyclic prefix,
wherein the cyclic prefix is a first cyclic prefix or a second cyclic prefix,
wherein a length of the second cyclic prefix is shorter than a length of the first cyclic prefix,
wherein a number of the plurality of symbols in the subframe varies on a time axis based on a length of the cyclic prefix,
wherein only a first symbol of the subframe includes the first cyclic prefix and remaining symbols of the subframe include the second cyclic prefix, and
wherein each symbol used for transmitting a synchronization signal among the plurality of symbols includes the first cyclic prefix.
2. The method according to claim 1 , wherein, the synchronization signal includes a primary synchronization signal or a secondary synchronization signal.
3. The method according to claim 1 , wherein a number of symbols on a frequency axis is fixed in the subframe.
4. An apparatus for transceiving a signal in a wireless communication system, the apparatus comprising:
a transceiver configured to transceive signals; and
a processor configured to:
control the transceiver; and
tranceive the signal from a transmitter in units of a subframe including a plurality of symbols,
wherein each of the plurality of symbols consists of a valid symbol and a cyclic prefix,
wherein the cyclic prefix is a first cyclic prefix or a second cyclic prefix,
wherein a length of the second cyclic prefix is shorter than a length of the first cyclic prefix,
wherein a number of the plurality of symbols in the subframe varies on a time axis based on a length of the cyclic prefix,
wherein only a first symbol of the subframe includes the first cyclic prefix and remaining symbols of the subframe include the second cyclic prefix, and
wherein each symbol used for transmitting a synchronization signal among the plurality of symbols includes the first cyclic prefix.
5. The apparatus according to claim 4 , wherein the synchronization signal includes a primary synchronization signal or a secondary synchronization signal.
6. The apparatus according to claim 4 , wherein a number of symbols on a frequency axis is fixed in the subframe.
