1. A method performed by a wireless device for controlling power in bidirectional Sidelink, SL, communications, the method comprising:
determining a Path Loss, PL, based transmit power for a Physical SL Feedback Channel, PSFCH; and
setting an initial PSFCH transmit power based on the PL-based transmit power for the PSFCH and limited by a Physical SL Shared Channel, PSSCH, transmit power level.
