The present invention relates to a wireless communication system and a terminal providing a wireless communication service and to a method by which a base station and a terminal transmit and receive data in an evolved universal mobile telecommunications system (E-UMTS) evolved from universal mobile telecommunications system (UMTS) or a long term evolution (LTE) system, and more particularly, to a method whereby, in requesting allocation of radio resources by a user equipment (UE), which has been allocated continuous allocation radio resources, from a base station, the UE compares an allocation time point of continuous allocation radio resources and a start time point of a radio resource request procedure and effectively transmit a radio resource allocation request.
