1. A method for transmitting a sounding reference signal (SRS) by a transmitting user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a channel state information-reference signal (CSI-RS);
transmitting, to the base station, a CSI report based on the CSI-RS, wherein the CSI report includes information indicating that the transmitting UE is located at an edge of a cell of the base station;
receiving, from the base station, first configuration information and second configuration,
wherein, based on the information indicating that the transmitting UE is located at the edge of the cell of the base station, the first configuration information includes only a timing advance offset configured to transmit the SRS,
wherein the second configuration information includes SRS configuration; and
based on the information indicating that the transmitting UE is located at the edge of the cell of the base station, transmitting the SRS to a receiving UE based on the first configuration information and the second configuration information.
