1. A method for sending status information in a mobile communications system, comprising:
- constructing a status protocol data unit (PDU), the status PDU used to provide positive and/or negative acknowledgements of acknowledged mode data (AMD) PDUs or portions of AMD PDUs; and
transmitting the constructed status PDU to a peer RLC entity,wherein the constructing step is performed by considering available resources such that the constructed status PDU fits to the total size of the available resources.

Abstract
Disclosed is a method of sending status information (STATUS PDU) in which a receiving side reports a data received state to a transmitting side in a mobile telecommunication system. A receiving side RLC entity considers an available radio resource to construct a status PDU fit to the size of the radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.

12. A method for sending status information from a receiving side radio link control (RLC) entity to a transmitting side RLC entity in a mobile communications system, the method comprising:
-
constructing by the receiving side RLC entity a STATUS PDU including information related to a reception state of RLC data PDUs by considering an available radio resource; and transmitting by the receiving side RLC entity the constructed STATUS PDU to the transmitting side RLC entity, wherein the constructing step comprises; selectively including NACK_SNs as many as being transmittable by using the available radio resource; and setting a value of ACK_SN to a value of VR(MS).

13. A receiving side radio link control (RLC) entity in a mobile communications system, comprising a module configured to:
-
check an available radio resource; construct a STATUS protocol data unit (PDU) by considering the available radio resource, wherein negative acknowledgement (NACK) elements are included in the STATUS PDU to be fit to the size of the available radio resource and a value of ACK_SN is set; and send the constructed STATUS PDU to a peer RLC entity.
