==Original Abstract Submitted==

Aspects of the disclosure provide method and apparatus for video coding. In some examples, an apparatus includes processing circuitry. The processing circuitry decodes prediction information of a first block from a coded video bitstream. The first block is a non-square block and the prediction information for the first block is indicative of a first intra prediction mode in a first set of intra prediction modes for a square block. Then, the processing circuitry remaps the first intra prediction mode to a second intra prediction mode in a second set of intra prediction modes that is used for the non-square block. The second set of intra prediction modes includes at least the second intra prediction mode that is not in the first set of intra prediction modes. Further, the processing circuitry reconstructs at least one sample of the first block according to the second intra prediction mode.
