Abstract: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

Abstract: This specification provides a method for performing an initial access by using a short transmission time interval (TTI) in a wireless communication system. More specifically, the method performed by the UE includes: receiving, from an eNB, system information including control information indicating a transmission time of an uplink signal; transmitting a random access preamble to the eNB; receiving, from the eNB, a random access response message including an uplink grant for transmitting the uplink signal in subframe #n; and transmitting, to the eNB, the uplink signal in subframe #n+k based on the control information, in which the k is a natural number smaller than 6. Accordingly, this specification has an effect that the initial access may be performed quickly by transmitting the uplink transmission of the RACH procedure faster.
