1. A method for performing wireless communication by a first device, the method comprising:
obtaining sidelink resource pool configuration information including a sidelink filter coefficient;
transmitting, to a second device, a demodulation reference signal (DMRS);
obtaining a reference signal power from a transmit power layer-3 (L3) filtered using the sidelink filter coefficient;
receiving, from the second device, a reference signal received power (RSRP) obtained from the DMRS;
obtaining a sidelink pathloss by subtracting the RSRP from the reference signal power;
determining a power for a physical sidelink shared channel (PSSCH) transmission based on the SL pathloss; and
performing the PSSCH transmission based on the power.
