Method and apparatus for video coding

An apparatus, comprising:

• processing circuitry configured to:
• decode prediction information of a first block from a coded video bitstream, wherein the first block is a non-square block and the prediction information of the first block is indicative of a first intra prediction mode in a first set of intra prediction modes for the non-square block, the first set of intra prediction modes includes a specific number of wide angle intra prediction modes that are not in a second set of intra prediction modes for a square block, and the first set of intra prediction modes does not include a specific number of missing intra prediction modes that are in the second set of intra prediction modes, and the specific numbers of the wide angle intra prediction modes and the missing intra prediction modes are a function of an aspect ratio of the first block;
• and
• reconstruct at least one sample of the first block according to the first intra prediction mode, wherein
• the second set of intra prediction modes includes directional modes from a bottom-left diagonal mode to a top-right diagonal mode, and
• the specific number of the wide angle intra prediction modes start from an angle outside a range of the directional modes from the bottom-left diagonal mode to a top-right diagonal mode.
