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 decoding a downlink control information (DCI) format contained in the downlink control channel; a step of checking a non-periodic sounding reference signal transmission instruction in the DCI format; and a step of transmitting a non-periodic sounding reference signal to the base station in accordance with the transmission instruction. Preferably, if the downlink control channel is received via an nth subframe, the non-periodic sounding reference signal is transmitted via an (n+k)th subframe (where k=4).
