METHOD AND APPARATUS FOR CONTROLLING CONTENTION RESOLUTION FOR ACCESS OF USER EQUIPMENT IN MOBILE COMMUNICATION BASE STATION

摘要

The present invention relates to a method and an apparatus for controlling access contention between user terminals (UEs) by a mobile communication base station (eNB), in which, although the eNB receives a Scheduled Transmission message for scheduling request including C-RNTI MAC Control Element from the UE normally in a contention based random access procedure, when information on an uplink data buffer size of the UE is not present, a physical downlink control channel (PDCCH) including UL Grant is transmitted to the UE, so that a contention resolution procedure can be successfully completed.
