1. A method for decoding a picture, the method comprising:
determining whether decoder side motion vector refinement (DMVR) and local illumination compensation (LIC) are activated for a current block of the picture; and
based on a determination that DMVR and LIC are activated for the current block:
determining one or more LIC parameters associated with decoding the current block;
refining one or more motion vectors associated with the current block; and
decoding the current block of the picture based on the one or more LIC parameters and the one or more refined motion vectors;
wherein the one or more LIC parameters are determined before or during the refinement of the one or more motion vectors.
