Method and apparatus for transmitting and receiving status report in a mobile communication system
First Claim
1. A method for transmitting a status report of an Automatic Repeat reQuest (ARQ) layer in a mobile communication system including the ARQ layer and a Hybrid Automatic Repeat reQuest (HARQ) layer, the method comprising:
- determining whether transmission of the status report is permitted, when a predetermined status report generation condition is satisfied in an ARQ receiving (Rx) entity;
if transmission of the status report is permitted, generating a status report depending on a reception status of ARQ packets up to the time the transmission of the status report is permitted; and
transmitting the generated status report to an ARQ transmitting (Tx) entity through an allocated transmission resource.

Abstract
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.

6. A method for receiving a status report of an Automatic Repeat reQuest (ARQ) layer in a mobile communication system including the ARQ layer and a Hybrid Automatic Repeat reQuest (HARQ) layer, the method comprising:
-
recording, by an HARQ transmitting/receiving (Tx/Rx) entity, an initial reception time of an HARQ packet, when the HARQ packet is initially received from an ARQ receiving (Rx) entity;
detecting a status report contained in the HARQ packet if it is determined that the HARQ packet has been successfully received, and sending the detected status report to an ARQ transmitting (Tx) entity together with the initial reception time of the HARQ packet; and
recognizing, by the ARQ Tx entity, the initial reception time as a generation time of the status report, and retransmitting retransmission-requested ARQ packets according to the status report. - View Dependent Claims (7, 8, 9)

10. An apparatus for transmitting a status report of an Automatic Repeat reQuest (ARQ) layer in a mobile communication system including the ARQ layer and a Hybrid Automatic Repeat reQuest (HARQ) layer, the apparatus comprising:
-
a status report generator for determining whether transmission of the status report is permitted, when a predetermined status report generation condition is satisfied in an ARQ receiving (Rx) entity, and if transmission of the status report is permitted, generating a status report depending on a reception status of ARQ packets up to the time the transmission of the status report is permitted; and
a transmitting entity for transmitting the generated status report to an ARQ transmitting (Tx) entity through an allocated transmission resource. - View Dependent Claims (11, 12, 13, 14)

15. An apparatus for receiving a status report of an Automatic Repeat reQuest (ARQ) layer in a mobile communication system including the ARQ layer and a Hybrid Automatic Repeat reQuest (HARQ) layer, the apparatus comprising:
-
an HARQ transmitting/receiving (Tx/Rx) entity for recording an initial reception time of the HARQ packet, when an HARQ packet is initially received from an ARQ receiving (Rx) entity, and if it is determined that the HARQ packet has been successfully received, detecting a status report contained in the HARQ packet, and outputting the detected status report together with the initial reception time of the HARQ packet; and
an ARQ transmitting (Tx) entity for recognizing the initial reception time as a generation time of the status report, and retransmitting retransmission-requested ARQ packets according to the status report. - View Dependent Claims (16, 17, 18)
