Method for transmitting a contention-based PUSCH 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 transmitting a contention-based PUSCH in a wireless communication system, the method comprising: receiving information for configuring a CB grant for transmitting a uplink data from the eNB; triggering a BSR when the uplink data is received from an upper layer; triggering a SR due to the triggered BSR and preparing transmission of the uplink data using the CB grant at a same time; transmitting the uplink data using the CB grant while the triggered SR is pending; monitoring an ACK indication from the eNB in response to the transmission of the uplink data; and canceling the pending BSR and SR if the UE receives the ACK indication from the eNB while the triggered SR is pending.
