DEVICE AND A METHOD FOR REQUESTING AN UPLINK RESOURCE ABOUT A SEMI-PERSISTENT SCHEDULING DATA SERVICE IN A WIDE BAND WIRELESS COMMUNICATION SYSTEM, CAPABLE OF AVOIDING THAT THE RESOURCES OF AN SPS SERVICE IS UNABLE TO BE REQUESTED

摘要

PURPOSE: A device and a method for requesting an uplink resource about a semi-persistent scheduling data service in a wide band wireless communication system are provided to reallocate uplink resources of an SPS(Semi-Persistent Scheduling) service.;CONSTITUTION: A communication controller(402) confirms whether uplink data is generated. If the uplink data is the uplink data of the SPS service, a message generator(404) generates an SPS exclusive BSR CE(Buffer Status Reporting Control Element) including the buffer state of the SPS service. An RF transmitter(416) transmits the SPS exclusive BSR CE.;COPYRIGHT KIPO 2010
