Method and apparatus for transmitting and receiving status report in a mobile communication system

摘要

A method and apparatus for transmitting/receiving a status report in a mobile communication system where Automatic Repeat reQuest (ARQ) and Hybrid Automatic Repeat reQuest (HARQ) operate together. An ARQ receiving (Rx) entity determines whether transmission of the status report is permitted, if a predetermined status report generation condition is satisfied. If the transmission of the status report is permitted, the ARQ Rx entity generates a status report depending on a reception status of ARQ packets received up to the time the transmission of the status report is permitted, and transmits the generated status report to an ARQ transmitting (Tx) entity through an allocated transmission resource. The ARQ Tx entity determines an initial reception time of an HARQ packet including the status report as a generation time of the status report, and performs retransmission according to the status report.
