1. A device for video decoding, comprising:
a processor configured to:
obtain intra prediction mode information associated with a video block;
determine an intra prediction mode of a plurality of intra prediction modes based on the intra prediction mode information;
obtain a first sub-block of the video block based on the intra prediction mode, wherein subsampling is used to obtain the first sub-block; and
decode a second sub-block of the video block based on the first sub-block of the video block, the intra prediction mode, and a parameter associated with the second sub-block.
