METHOD FOR TRANSMITTING A SRS IN A MULTIPLE COMPONENT CARRIER SYSTEM CAPABLE OF REDUCING UNNECESSARY INTERFERENCE WITH ANOTHER TERMINAL BY CONTROLLING TRANSMISSION OF A UL REFERENCE SIGNAL AND A DEVICE THEREOF

摘要

PURPOSE: A method for transmitting a SRS(Sounding Reference Signal) in a multiple component carrier system and a device thereof are provided to control transmission of a UL reference signal, thereby preventing unnecessary power consumption of a terminal.;CONSTITUTION: A terminal receives an SRS setup message for a UL component carrier from a base station(S1510). The terminal starts counting of an SRS stop timer(S1520). When a counting restart condition and a counting stop condition are not generated, the terminal determines that the counting of the SRS stop timer is terminated(S1530~S1550). When the counting of the SRS stop timer is terminated, the terminal adjusts an SRS transmission cycle(S1560).;COPYRIGHT KIPO 2012
