1. A method for video decoding in a decoder, comprising:
decoding at least one syntax element of a block to be reconstructed from a coded video bitstream, the at least one syntax element indicative of the block being a non-square block that has a rectangular shape; and
predicting a sample of the non-square block based on a first set of intra prediction directions for the non-square block, the first set of intra prediction directions including a first subset of intra prediction directions in a second set of intra prediction directions for a square block and not including a second subset of intra prediction directions in the second set of intra prediction directions, wherein
the second subset of intra prediction directions that is not shared with the non-square block is outside a first angular subrange covered by the first subset of intra prediction directions that is shared with the non-square block, and
the second subset of intra prediction directions is at an end of an angular range of the second set of intra prediction directions for the square block.
