Abstract
(EN)
The present disclosure provides a method for controlling a transmission power of a sidelink terminal in a wireless communication system, the method comprising the steps of: acquiring, by a first sidelink terminal, control information on whether a closed loop power control (CLPC) process is operated; transmitting a sidelink measurement signal to a second sidelink terminal on the basis of a determination result; receiving a sidelink signal transmitted according to a transmission power value configured on the basis of the sidelink measurement signal; and providing transmission power control (TPC) command information on the basis of the transmission power value of the received sidelink signal.
