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

WIPO Patent Application WO/2017/135773

A1

Disclosed are a method for transmitting a sounding reference signal to a base station by a terminal and an apparatus for supporting the same. Particularly, disclosed is a sounding reference signal transmission method comprising: determining a transmission time point of a first SRS within a first TTI, which has a length shorter than the length of one subframe, on the basis of the first TTI; and transmitting the first SRS at the determined transmission time point, wherein a frequency resource at which the first SRS is transmitted is configured independently from a frequency resource at which a second SRS based on a second TTI having a length corresponding to the length of one subframe is transmitted.
