Abstract
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 radio link control (RLC) entity considers an available radio resource to construct a status PDU fit to a size of the available radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.
Claims11
A method for sending status information in a mobile communications system, the method 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 radio link control (RLC) entity,
- wherein the constructing step is performed by considering available resources such that the constructed status PDU fits to a total size of the available resources, and
- wherein the available resources refer to the total size of RLC PDUs indicated by a lower layer.
A receiving side radio link control (RLC) entity in a mobile communications system, the RLC entity 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 a size of the available resource;
- set a value of ACK_SN;
- and
- send the constructed STATUS PDU to a peer RLC entity,
- wherein the available radio resource refers to a total size of RLC PDUs indicated by a lower layer.
