1. An apparatus for transmitting a sounding reference signal (SRS) through an unlicensed band, the apparatus comprising:
a processor; a memory; and a communication device,
wherein the processor executes a program stored in the memory to perform:
receiving a downlink control information (DCI) for triggering an SRS transmission through uplink multiple subframes from a base station;
determining an SRS subframe for the SRS transmission among the uplink multiple subframes on the basis of SRS transmission position information of 2 bits included in the DCI received from the base station; and
transmitting the SRS in the SRS subframe,
wherein the SRS transmission position information of 2 bits indicates that the SRS is not transmitted, or the SRS is configured in a first subframe of the uplink multiple subframes, or the SRS is configured in a second subframe of the uplink multiple subframes, or the SRS is configured in a last subframe of the uplink multiple subframes.
