Abstract
Discussed 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.
Claims11
A receiving side radio link control (RLC) entity in a mobile communication system, comprising:
- a processor configured to construct a status protocol data unit (PDU), the status PDU used to provide at least one of a positive acknowledgement and a negative acknowledgement of radio link control (RLC) data PDUs, wherein the RLC data PDUs comprise at least one of acknowledged mode data (AMD) PDUs and portions of AMD PDUs;
- and
- a transceiver configured to transmit the constructed status PDU to a peer RLC entity,
- wherein the status PDU is constructed by considering available resources such that the constructed status PDU fits to a total size of the available resources and by using a receive state variable and a maximum status transmit state variable, and
- wherein the status PDU is for AMD PDUs with sequence numbers that include a sequence number of the receive state variable and at least one sequence number between the sequence number of the receive state variable and a sequence number of the maximum status transmit state variable.
