Abstract

A PDCP status report can be transmitted with reduced radio resources by transmitting the reception success or failure of a series of PDCP service data units (SDUs) in the form of a bitmap when configuring the PDCP status report. A PDCP control packet data unit (PDU) is generated to communicate a status report to a transmitting node for one or more PDCP SDUs transmitted from the transmitting node. The PDCP control PDU includes a data/control (D/C) bit field to indicate the PDCP control PDU is a control PDU, a control PDU type field to indicate a type of corresponding control information, a sequence number field to indicate a first missing PDCP SDU, and a bitmap field for a variable length bitmap. A bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received.
