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.
Claims7
A method for data transmission in a wireless communication system including a User Equipment (UE) and a radio access network (RAN), the method utilized in the RAN and comprising:
- receiving an uplink Radio Link Control (RLC) data protocol data unit (PDU) including a polling request from the UE for requesting the RAN to transmit a RLC status PDU;
- transmitting a Medium Access Control (MAC) PDU to the UE, wherein the MAC PDU includes an RLC status PDU indicating at least one negative acknowledgement corresponding to at least one unsuccessfully received uplink RLC data PDU;
- receiving an acknowledgement signal in response to the MAC PDU including the RLC status PDU from the UE;
- and
- allocating an uplink resource to the UE in response to the acknowledgement signal, wherein the uplink resource is for the UE to retransmit at least one uplink data packet corresponding to the unsuccessfully received uplink RLC data PDU before a request for data transmission is received.
