METHOD AND APPARATUS FOR TRANSMITTING A SOUNDING REFERENCE SIGNAL

摘要

PURPOSE: A method and apparatus for transmitting an aperiodic sounding reference signal is provided to accurately conduct an upper link scheduling by providing a transfer method of a sounding reference signal when the aperiodic sounding reference signal is triggered together with other uplink transmission. CONSTITUTION: A terminal receives a setting for transmitting a periodic CQI (Channel Quality Indicator) from a base station (S810). The terminal receives a setting for transmitting SRS (Sounding reference Signal) from the base station. The terminal monitors PDCCH for detecting a positive SRS request (S830). When detecting the positive SRS request, an SRS sub-frame for transmitting the SRS is determined (S850). The SRS is transmitted from the SRS sub-frame to the base station.
