Method for performing an ACK/NACK indication based on the uplink grants over multiple subframes in a wireless communication system and a device therefor
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an ACK/NACK indication based on the uplink grants over multiple subframes in a wireless communication system, the method comprising: starting a timer when an uplink grant is received from an eNB, wherein the uplink grant is valid while the timer is running; transmitting data using the uplink grant if the data is generated while the timer is running; monitoring an ACK indication or an or a NACK indication for the transmitted data on a subframe; checking whether the timer is running or not if the ACK indication for the transmitted data is not received on the subframe; and retransmitting the data using the uplink grant if the timer is running.
