1. A method for transmitting a status report in a mobile communication system, comprising:
- (A) starting, by a receiving side, a timer at a lower edge of a reception window when the receiving side receives a PDU (Protocol Data Unit) from a sending side out of sequence,; and
(B) transmitting, by the receiving side, to the sending side, a status report including information about PDUs which have not been received until the expiration of the timer, if the timer expires in a state that a PDU corresponding to the lower edge of the reception window is not received.

Abstract
A method for improving radio resources, a method for transmitting a status report, and a receiving apparatus (receiver) in a mobile communication system are disclosed. In transmitting a status report by a receiving side RLC, although data that has not been received (missing PDU) is discovered, the receiving side does not immediately request its retransmission but transmits the status report after the lapse of a certain time (namely, a time point at which a timer expires), to thus reduce radio resources consumed for transmission of the status report.

8. An apparatus comprising:
-
a reception buffer that stores PDUs transmitted by a sending side; a timer that operates during a pre-set time period if there is a PDU which has not been received at a lower edge of a reception window; and a processing unit that sets the reception window, determines whether there is a PDU which has not been received among the PDUs that have been received by the reception window, by using SNs (Sequence Numbers) of the PDUs, and starts the timer for the lower edge of the reception window for which there exists the first PDU which has not been received. - View Dependent Claims (9, 10)
