Abstract:
1. A method of transmitting a reception status report in a radio link control (RLC) protocol layer of a user equipment (UE) which receives data transmitted from a base station in a mobile communication system, the method comprising: periodically transmitting the reception status report of at least one first data block in the RLC protocol layer every first time period value (T changing the first time period value (T periodically transmitting reception status report of at least one second data block every second time period value (T wherein the at least one parameter includes a time period value for transmitting the reception status report, wherein the at least one predefined condition is satisfied if intensity of a reference signal transmitted from the base station becomes smaller than a predefined first threshold value, if intensity of a reference signal transmitted from a neighboring base station becomes greater than a predefined second threshold value, or when the user equipment transmits a measurement report message to the base station, and wherein the second time period value (T
