Abstract
The present description discloses a method for transmitting an uplink signal through a non-licensed band from a terminal in a wireless communication system by applying carrier aggregation techniques. More specifically, the method is characterized by comprising the steps of: receiving an uplink scheduling grant from a base station; determining the availability of a non-licensed band; transmitting a signal for reserving resources if a non-licensed band is available; and transmitting an uplink signal to the base station via the non-licensed band on the basis of the uplink scheduling grant.

15. A method of transmitting an uplink signal via a non-licensed band by a user equipment in a wireless communication system to which a carrier aggregation scheme is applied, the method comprising:
-
receiving an uplink scheduling grant from an eNode B; detecting a resource reservation signal of a different user equipment; if the resource reservation signal of the different user equipment corresponds to a predetermined signal, configuring the non-licensed band as an available resource; and transmitting the uplink signal to the eNode B via the non-licensed band based on the uplink scheduling grant. - View Dependent Claims (16, 17, 18, 19, 20)

21. A user equipment device in a wireless communication system to which a carrier aggregation scheme is applied, comprising:
-
a receiving module configured to receive an uplink scheduling grant from an eNode B; a processor configured to detect a resource reservation signal of a different user equipment device and to set the non-licensed band as an available resource if the resource reservation signal of the different user equipment device corresponds to a predetermined signal; and a transmitting module configured to transmit an uplink signal to the eNode B via the non-licensed band based on the uplink scheduling grant. - View Dependent Claims (22, 23, 24, 25, 26)
