1. A method for decoding video data, comprising:
receiving a current frame including a current coding block, wherein the current coding block has a plurality of subblocks, and wherein the plurality of subblocks are associated with different subblock-level motion vectors, and include a first subblock located at a boundary of the current coding block;
determining a block-level motion vector of the current coding block;
determining a first subblock-level motion vector of the first subblock; and
generating motion compensation data of the first subblock based on the block-level motion vector of the current coding block and the first subblock-level motion vector of the first subblock.
