1. A method for video decoding in a decoder, comprising:
decoding, by a processor and from a coded video bitstream, transform coefficients associated with a coding block that is an L-shaped partition of a picture;
partitioning the L-shaped partition of the picture into a plurality of rectangular sub-blocks when the coding block is the L-shaped partition, each corner of the L-shaped partition being a right angle;
determining, by the processor, residuals of each of the plurality of rectangular sub-blocks in the coding block based on the transform coefficients of the respective rectangular sub-block; and
reconstructing, by the processor, samples of the coding block based on the residuals of the coding block.
