Method for dynamic allocation of radio resources in wireless communication system and device therefor

摘要

The present invention relates to a method for transmitting an uplink signal of a terminal using multiple component carriers in a wireless communication system and, more particularly, to a method for transmitting an uplink signal of a terminal using multiple component carriers in a wireless communication system which supports carrier aggregation, comprising the steps of: receiving setting information on a second-type component carrier from a base station through a first-type component carrier; and transmitting an uplink signal to the base station through the second-type component carrier, wherein the use of the second-type component carrier for a specific subframe is changed according to the setting information.

1. A method of transmitting an uplink signal, which is transmitted by a user equipment using a plurality of component carriers (CCs) in a wireless communication system supporting carrier aggregation, comprising:
receiving a time division duplex uplink-downlink (TDD UL-DL) configuration for a second component carrier through a physical control channel or a higher layer signaling, wherein the TDD UL-DL configuration indicates an uplink-downlink resource configuration of a plurality of subframes; receiving configuration information indicating at least one subframe among the plurality of subframes on the second component carrier from an eNode B via a first component carrier, wherein each of the indicated at least one subframe is a downlink subframe according to the TDD UL-DL configuration; if control information for the indicated at least one subframe is not received prior to the indicated at least one subframe, detecting the control information for the indicated at least one subframe by performing a blind decoding in uplink subframes indicated by the TDD UL-DL configuration; and when the detected control information is an uplink grant, transmitting the uplink signal to the eNode B in the indicated at least one subframe via the second component carrier.
