A method for transmitting a sounding reference signal, SRS, by a user equipment, UE, in a wireless communication system, the method comprising: receiving, from a base station, configuration information related to SRS transmission, wherein the configuration information includes i) a first parameter set related to transmission of a first SRS and ii) a second parameter set related to transmission of a second SRS; receiving, from the base station, downlink control information, DCI, wherein the DCI includes a 2-bit field related to a triggering of at least one of the first SRS and the second SRS; and transmitting, to the base station, at least one of the first SRS and the second SRS, based on the DCI, wherein the first SRS and the second SRS are transmitted in a same subframe, wherein the subframe is based on a normal uplink subframe which is different from a special subframe, wherein the first SRS is transmitted in a last symbol of the subframe, wherein the second SRS is transmitted in one or more symbols among symbols other than the last symbol in the subframe, wherein codepoints related to the 2-bit field include a first codepoint, a second codepoint and a third codepoint, wherein the first codepoint is mapped to the first parameter set, the second codepoint is mapped to the second parameter set, and the third codepoint is mapped to the first parameter set and the second parameter set, wherein, based on the 2-bit field representing the first codepoint, the first SRS is transmitted, wherein, based on the 2-bit field representing the second codepoint, the second SRS is transmitted, and wherein, based on the 2-bit field representing the third codepoint, the first SRS and the second SRS are transmitted. receiving, from a base station, configuration information related to SRS transmission, wherein the configuration information includes i) a first parameter set related to transmission of a first SRS and ii) a second parameter set related to transmission of a second SRS; receiving, from the base station, downlink control information, DCI, wherein the DCI includes a 2-bit field related to a triggering of at least one of the first SRS and the second SRS; and transmitting, to the base station, at least one of the first SRS and the second SRS, based on the DCI, wherein the first SRS and the second SRS are transmitted in a same subframe, wherein the subframe is based on a normal uplink subframe which is different from a special subframe, wherein the first SRS is transmitted in a last symbol of the subframe, wherein the second SRS is transmitted in one or more symbols among symbols other than the last symbol in the subframe, wherein codepoints related to the 2-bit field include a first codepoint, a second codepoint and a third codepoint, wherein the first codepoint is mapped to the first parameter set, the second codepoint is mapped to the second parameter set, and the third codepoint is mapped to the first parameter set and the second parameter set, wherein, based on the 2-bit field representing the first codepoint, the first SRS is transmitted, wherein, based on the 2-bit field representing the second codepoint, the second SRS is transmitted, and wherein, based on the 2-bit field representing the third codepoint, the first SRS and the second SRS are transmitted.
