1. A method of video coding, comprising:
obtaining a coding block from a video signal;
obtaining a plurality of spatial neighboring blocks based on the coding block, wherein the plurality of spatial neighboring blocks comprise multiple left spatial neighboring blocks and multiple above spatial neighboring blocks;
obtaining up to one left non-scaled motion vector predictor (MVP) based on the multiple left spatial neighboring blocks;
obtaining up to one above non-scaled MVP based on the multiple above spatial neighboring blocks;
deriving an MVP candidate list based on the coding block, the multiple left spatial neighboring blocks, and the multiple above spatial neighboring blocks by excluding scaled spatial MVP candidates from the MVP candidate list, wherein the MVP candidate list comprises the up to one left non-scaled MVP and the up to one above non-scaled MVP;
receiving an index indicating an MVP in the MVP candidate list; and
obtaining a prediction signal of the coding block based on the MVP indicated by the index.
