1. A method for video decoding, the method comprising:
determining to perform local illumination compensation (LIC) on a current block using LIC parameters;
obtaining a local illumination compensation parameter candidate list;
obtaining, for the current block, an LIC parameter index associated with the LIC parameter candidate list for performing LIC on the current block;
selecting an LIC parameter set from the LIC parameter candidate list based on the LIC parameter index; and
decoding the current block based on the LIC parameter set.
