First Claim
Patent Images
1. A method for transmitting a status report in a packet data convergence protocol (PDCP) layer of a mobile communication system, the method comprising:
- generating, by a receiving side, the status report for one or more PDCP service data units (SDUs) that were transmitted from a transmitting side,wherein the status report indicates whether or not the transmitted PDCP SDUs have been successfully received at the receiving side,wherein the status report is generated in a form of a bitmap, andwherein a specific bit in the bitmap indicates whether or not a corresponding one of the PDCP SDUs has successfully been received, andtransmitting, by the receiving side, the status report to the transmitting side.

Abstract
Disclosed is a status report transmission of the PDCP layer for a PDCP status report which can reduce radio resources, by transmitting the reception success or failure of a series of PDCP SDUs in the form of a bitmap when configuring the PDCP status report for reporting a reception status of the PDCP SDU to another party in the PDCP layer in the LTE system.

8. A receiver, comprising:
-
processing circuitry configured to generate a status report in a packet data convergence protocol (PDCP) layer of a mobile communication system for one or more PDCP service data units (SDUs) that were transmitted from a transmitting entity, wherein the status report indicates whether or not the transmitted PDCP SDUs have been successfully received at the receiver, wherein the status report is generated in a form of a bitmap, and wherein a specific bit in the bitmap indicates whether or not a corresponding one of the PDCP SDUs has successfully been received, and a transmitter configured to transmit the status report to the transmitting entity. - View Dependent Claims (9, 10, 11, 12, 13, 14)
