1. A method of performing automatic repeat request (ARQ) in a wireless communication system, the method performed by a receiver and comprising:
- detecting whether at least one data block to be received from a transmitter is missed;
starting a timer when the at least one data block is detected as missed;
stopping the timer when the at least one data block is received from the transmitter while the timer is running, in order to prevent a triggering of a status report before the timer expires; and
transmitting the status report to the transmitter after the timer expires, wherein the status report comprises a positive acknowledgement indicating receipt of at least one received data block.

Abstract
A method which can reduce loss in data transmission is provided. A data block is prepared in a high-level layer and the data block is transmitted in a low-level layer. Status report information associated with reception or non-reception of the data block is received through the low-level layer. When a receiver fails to receive data transmitted from a transmitter, the transmitter can rapidly recognize the reception failure and can retransmit the data.

8. A receiver for performing automatic repeat request (ARQ) in a wireless communication system, the receiver comprising a Radio Link Control (RLC) entity, wherein the RLC entity is configured to:
-
detect whether at least one data block to be received from a transmitter is missed; start a timer when the at least one data block is detected as missed; stop the timer when the at least one data block is received from the transmitter while the timer is running, in order to prevent a triggering of a status report before the timer expires; and transmit the status report to the transmitter after the timer expires, wherein the status report comprises a positive acknowledgement indicating receipt of at least one received data block. - View Dependent Claims (9, 10)
