An enhanced RLC STATUS PDU format is used in a wireless communication network in which a sender transmits AMD PDUs to a receiver, and the receiver responds a STATUS PDU. In the STATUS PDU, an ACK_SN field is provided for indicating the SN of a next not received AMD PDU which is not reported as missing in the STATUS PDU, and an Efield is provided for indicating whether a set of NACK_SN, E, and Efields follows or not. The NACK_SN field indicates a AMD PDU that has been detected as lost at the receiver. The Efield indicates whether a set of SOstart, SOend, and Efields follows or not. The SOstart field indicates the first byte in the AMD PDU with SN=NACK_SN that has been detected as lost. The SOend field indicates the last byte in the AMD PDU with SN=NACK_SN that has been detected as lost.

In a method for optimizing discontinuous reception mechanism in random access or scheduling request, the user equipment behaves according to a TTI window and a contention resolution timer so that the user equipment is at active time to monitor PDCCH. In the random access, the UE is at active time while a PDCCH indicating a new transmission addressed to the C-RNTI of the UE has not been received after successful reception of a Random Access Response for the non-contention preamble. In the scheduling request, the UE is at active time while an UL grant for the UE has not been received after SR has been sent.

A method for providing a buffer status report in a mobile communication network is implemented between a base station and a user equipment. When data arrives to buffers of the user equipment and the priority of a logical channel for the data is higher than those of other logical channels for existing data in the buffers, a short buffer status report associated with the buffer of a logical channel group corresponding to the arrival data is triggered. The user equipment is based on obtained resources allocated by the base station to fill all data of the buffer of the logical channel group in a Protocol Data Unit. If all data of the buffer of the logical channel group corresponding to the arrival data can be completely filled in the Protocol Data Unit, the short buffer status report is canceled. Otherwise, the user equipment transmits the short buffer status report.
