METHOD AND APPARATUS OF CONTENTION BASED UPLINK TRANSMISSION IN MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A contention based uplink transmission apparatus in a mobile communication system is provided to improve transceiving performance in a contention based uplink transmission. CONSTITUTION: A receiver(420) receives downlink control information corresponding to each CB C-RNTI(Contention Based Cell-Radio Network Temporary Identity) through a PDCCH(Physical Downlink Control Channel) corresponding to a contention based uplink. A selecting unit(440) selects one or more contention based identifiers based on the transmission standard of the contention based uplink and down link control information. A data transmission part(450) performs the contention based uplink transmission using the object CB C-RNTI.
