1. A method of video encoding comprising:
determining a predetermined condition associated with signaling data for a current block included in a current picture, the predetermined condition specifying whether a maximum number of merge mode candidates is different from a maximum number of intra block copy (IBC) candidates;
setting, based on the predetermined condition, a size of an index included in the signaling data for a candidate list of vector predictors to one of (i) the maximum number of merge mode candidates and (ii) the maximum number of IBC candidates;
constructing the candidate list of vector predictors;
retrieving a vector predictor from the candidate list of vector predictors in accordance with the index that has a value that does not exceed the size of the index;
encoding the current block in accordance with the retrieved vector predictor; and
generating a coded video bitstream including the current picture and the signaling data.
