Method for obtaining information about cyclic prefix in wireless communication system and device for same
2017
Disclosed are a method for a terminal obtaining information about a cyclic prefix in a wireless communication system and a device for same. More particularly, the method comprises the steps of: detecting a particular synchronization signal received from a base station by means of a first symbol of a first subframe; detecting the particular synchronization signal received from the base station by means of a second symbol of a second subframe; and obtaining information about a CP applied to the transmission of the particular synchronization signal on the basis of an offset value between an index of the first symbol and an index of the second symbol, wherein the second subframe comprises a subframe of which symbol indices are permuted in accordance with a preset pattern with respect to the CP, and the offset value between the index of the first symbol and the index of the second symbol can indicate a CP type corresponding to the CP among one or more CP types supported in the wireless communication system.
