Abstract
The present invention relates to a method and apparatus for determining whether or not to transmit an uplink control signal in a first subframe according to whether or not a subframe (the first frame) corresponding to a transmission time of the uplink control signal is within an active time, or whether or not the first subframe is one of a constant number of subframes after the last subframe of the active time, and the active time is a time for the reception of resource allocation information for data retransmission.

16. A method for transmitting an uplink control signal to a base station by a user equipment for which discontinuous reception is configured, the method comprising:
if a subframe corresponding to a transmission timing of the uplink control signal (hereinafter, first subframe) is not within an active time, determining whether to transmit the uplink control signal in the first subframe according to whether the first subframe is one of a prescribed number of subframes after a last subframe of the active time and whether the last subframe of the active time is a subframe for receiving resource assignment information for data retransmission (hereinafter, second subframe). - View Dependent Claims (17, 18, 19, 20, 21)

22. A user equipment for transmitting an uplink control signal to a base station, for which discontinuous reception is configured, the user equipment comprising:
-
a radio frequency (RF) unit configured to transmit a signal; and a processor configured to control the RF unit, wherein, if a subframe corresponding to a transmission timing of the uplink control signal (hereinafter, first subframe) is not within an active time, the processor determines whether to transmit the uplink control signal in the first subframe, according to whether the first subframe is one of a prescribed number of subframes after a last subframe of the active time and whether the last subframe of the active time is a subframe for receiving resource assignment information for data retransmission (hereinafter, second subframe), and the processor controls the RF unit according to the determination. - View Dependent Claims (23, 24, 25, 26)

30. A base station for receiving an uplink control signal from a user equipment for which discontinuous reception is configured, the base station comprising:
-
a radio frequency (RF) unit configured to transmit a signal; and a processor configured to control the RF unit, wherein, if a subframe corresponding to a reception timing of the uplink control signal (hereinafter, first subframe) is not within an active time, the processor determines whether to receive the uplink control signal in the first subframe according to whether the first subframe is one of a prescribed number of subframes after a last subframe of the active time and whether the last subframe of the active time is a subframe for receiving resource assignment information for data retransmission (hereinafter, second subframe).
