1. A method for video decoding in a decoder device, comprising:
receiving coded data associated with a current block in a current picture, the current block including a plurality of sub-blocks;
identifying a first neighboring sub-block in the current picture for a first subset of the sub-blocks according to a first direction, the first neighboring sub-block being adjacent to and outside the current block, and the first subset of the sub-blocks including all sub-blocks of the current block that are located in the first direction with respect to the first neighboring sub-block, wherein the first direction is one of a vertical direction, a horizontal direction, or a diagonal direction;
identifying a second neighboring sub-block in the current picture for a second subset of the sub-blocks according to the first direction, the second neighboring sub-block being adjacent to and outside the current block and the second subset of the sub-blocks including all sub-blocks of the current block that are located in the first direction with respect to the second neighboring sub-block;
determining a first motion information predictor based on first prediction information of the first neighboring sub-block and determining a second motion information predictor based on second prediction information of the second neighboring sub-block;
determining first sub-block motion vectors for sub-blocks in the first subset by adjusting the first motion information predictor and determining second sub-block motion vectors for sub-blocks in the second subset by adjusting the second motion information predictor;
reconstructing the first subset of the sub-blocks based on the first sub-block motion vectors and reconstructing the second subset of the sub-blocks based on the second sub-block motion vectors; and
reconstructing the current block for output based on the reconstructed first subset of the sub-blocks and the second subset of the sub-blocks.
