    Abstract: A method for transmitting data in a wireless communication system including a User Equipment (UE) and a radio access network (RAN) includes the following steps. Firstly, the RAN transmits a MAC protocol data unit (PDU) to the UE. Afterwards, the UE returns an acknowledgement signal in response to the MAC PDU. When the RAN receives the acknowledgement signal, it allocates an uplink resource for the UE to transmit data.
