摘要：
In the present invention, a user equipment (UE) receives an UL grant that can be used while the UE is not in RRC_CONNECTED state. If the UE receives a message indicating to leave RRC_CONNECTED state, the UE starts a time alignment timer (I-TAT) when the UE leaves RRC_CONNECTED state. The UE transmits UL data using the UL grant if the UL data becomes available for transmission when the UE is not in RRC_CONNECTED state and if the I-TAT is running.
