SRS TRANSMISSION BANDWIDTH DETERMINATION METHOD AND A SYSTEM THEREOF, CAPABLE OF EFFICIENTLY PERFORMING AN UPLINK RESOURCE ALLOCATION BY A BASE STATION IN A MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A SRS transmission bandwidth determination method and a system thereof are provided for a base station to efficiently determine SRS transmission bandwidth in consideration of an uplink channel environment of a terminal.;CONSTITUTION: A user device(400) calculates transmission power about a SRS bandwidth having different length which is possible to transmit(S630). The user device extracts transmission power which does not exceed maximum transmission power from the calculated transmission power. The user device determines SRS candidate bandwidth(S640). A node B(500) receives the SRS candidate bandwidth transmitted from the user device. The base station determines the SRS transmission bandwidth(S670).;COPYRIGHT KIPO 2010
