Abstract:
1. A method for transmitting data by a relay in a wireless communication system, the method comprising: generating a parameter for controlling discontinuous reception (DRX) of a second component carrier discriminated from a parameter for controlling discontinuous reception of a first component carrier used by a base station; and transmitting the generated parameter for controlling the discontinuous reception of the second component carrier to a user equipment; wherein generating of the parameter for controlling the discontinuous reception (DRX) of the second component carrier further comprises: setting the parameter for controlling the discontinuous reception of the second component carrier so as to be identical to the parameter for controlling the discontinuous reception of the first component carrier with reference to the parameter for controlling the discontinuous reception of the first component carrier used by the base station, and in consideration of at least one of a channel state and a link performance of the user equipment and with reference to a DRX cycle and an active time or a DRX on-duration of the first component carrier, setting a DRX cycle of the second component carrier so as to be identical to the DRX cycle of the first component carrier, or setting a DRX on-duration of the second component carrier so as to be identical to the DRX on-duration of the first component carrier, or setting the DRX cycle and the DRX on-duration of the second component carrier so as to be identical to the DRX cycle and the DRX on-duration of the first component carrier, respectively.
