Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method performed by a first device in a wireless communication system, the method comprising:
obtaining synchronization related to sidelink (SL) communication from a synchronization reference;
obtaining first information related to a first power control parameter;
obtaining second information related to a second power control parameter;
obtaining third information related to a third power control parameter;
determining a first transmit power value based on the first information and a downlink (DL) pathloss between a base station and the first device;
determining a fourth transmit power value based on a minimum value between a second transmit power value and a third transmit power value, wherein the second transmit power value is related to the second information and the DL pathloss, and the third transmit power value is related to the third information and a SL pathloss between the first device and a second device;
transmitting, to the second device, a sidelink synchronization signal block (S-SSB) based on the first transmit power value and the synchronization; and
transmitting, to the second device, a physical sidelink shared channel (PSSCH) or a physical sidelink control channel (PSCCH) based on the fourth transmit power value.
