Abstract: A method and device for performing a contention based random access procedure by a mobile communication terminal in communication with a base station. The method according to an embodiment includes transmitting a random access preamble message to the base station; receiving a random access response from the base station, the random access response including a timing advance command; determining a status of a mobile communication terminal time alignment timer; and ignoring the timing advance command if the mobile communication terminal time alignment timer is determined to be running in the determining step.

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.

Abstract: A status report transmission of the PDCP layer for a PDCP status report can reduce 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 for reporting a reception status of PDCP SDUs to another party in the PDCP layer. A PDCP control packet data unit (PDU) is generated to communicate a status report for one or more PDCP SDUs transmitted from a 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 specific bit in the variable length bitmap indicates whether a corresponding one of the one or more PDCP SDUs has been successfully been received. The PDCP control PDU is transmitted to the transmitting node.
