METHOD AND APPARATUS OF TRANSMITTING APERIODIC SOUNDING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An aperiodic sounding reference signal transmission method and apparatus are provided to efficiently transmit a sounding reference signal through one and more component carriers. CONSTITUTION: An RF(Radio Frequency) part transmits or receives a radio signal. A processor is connected to the RF part. The processor receives the triggering bit of an aperiodic SRS(Sounding Reference Signal)(S100). The triggering bit triggers the transmission of the aperiodic SRS. The triggering bit is transmitted by one PDCCH(Physical Downlink Control Channel). The processor transmits the aperiodic SRS through one and more uplink component carriers among a plurality of uplink configuration carrier waves(S110). A base station comprises the processor, the RF part, and a memory.
