METHOD AND APPARATUS FOR TRANSMITTING A SIGNAL IN A WIRELESS COMMUNICATION SYSTEM

摘要

One embodiment of the present invention relates to a method for transmitting a signal to an unlicensed band of a base station in a wireless communication system. The method comprises the steps of: transmitting at least one of a preamble and a reservation signal, if it is determined through carrier sensing that the unlicensed band is available; and transmitting a PDSCH on the unlicensed band immediately after the transmission of at least one of the preamble and the reservation signal. The preamble enables a terminal to acquire reception synchronization for at least one of the reservation signal and the PDSCH.
