1. A method for transmitting a status report by a user equipment (UE) in a mobile telecommunications system, comprising:
- (A) receiving, by a radio resource control (RRC) entity of the UE, a threshold value related to a status report from a network, wherein the threshold value is decided by the network;
(B) receiving, by a radio link control (RLC) entity of the UE, data transmitted from the network and storing the data in a reception buffer of the UE; and
(C) determining, by the radio link control (RLC) entity of the UE, whether to transmit the status report to the network by checking a total amount of the data stored in the reception buffer of the UE and the threshold value,wherein the threshold value is a predetermined value indicating a ratio of the total byte size of data stored in the reception buffer of the UE to a total byte size of the reception buffer of the UE,wherein the total amount of the data stored in the reception buffer of the UE is expressed as a calculated ratio of the total amount of the data stored in the reception buffer of the UE to a total size of the reception buffer of the UE,wherein the status report is transmitted to the network if the calculated ratio is equal to or larger than the threshold value.

Abstract
Disclosed is a method for enhancing of controlling radio resource and transmitting a Status Report in a mobile telecommunications system, and a receiver of mobile telecommunications system. When any PDUs that have not been received (‘missing PDUs’) occur, a receiving RLC entity does not immediately request re-transmission about the ‘missing PDUs’. Rather, only when missing PDUs more than a predetermined number occur, the receiving RLC entity requests the re-transmission. Accordingly, an amount of radio resources required to transmit a Status Report can be reduced.
