METHOD FOR TRANSMITTING A SOUNDING REFERENCE SIGNAL IN A WIRELESS COMMUNICATION SYSTEM, AND APPARATUS FOR SAME

摘要

The present invention relates to a method in which user equipment transmits a non-periodic sounding reference signal in a wireless communication system. In detail, the method comprises: a step of receiving a downlink control channel from a base station; a step of checking carrier indication field (CIF) information of a downlink control information (DCI) format contained in the downlink control channel; and a step of transmitting a non-periodic sounding reference signal to the base station in accordance with the CIF information, wherein said CIF information comprises a triggering message of the non-period sounding reference signal.
