Claim 0:
1. A method for video encoding, comprising:
receiving samples of a current block in a current picture;
determining, by processing circuitry, a prediction mode for coding the current block, the prediction mode combining an intra prediction and an inter prediction, the intra prediction being based on at least a first reference sample in the current picture, and the inter prediction being based on at least a second reference sample in a reference picture of the current picture;
encoding the samples of the current block according to the prediction mode to obtain encoded data, the encoding including, in response to the prediction mode being one of a combined intra/inter prediction (CIIP) mode and an inter position dependent prediction combination (PDPC) mode:
determining a transform set associated with at least one of a Planar intra prediction mode or a DC intra prediction mode,
selecting, from the transform set, a transform kernel associated with the at least one of the Planar intra prediction mode or the DC intra prediction mode for use in a secondary transform, and
encoding residual samples of the current block by performing a primary transform, the secondary transform after the primary transform, and a quantization after the secondary transform; and

generating a coded video bitstream, the coded video bitstream including the encoded data and prediction information indicative of the prediction mode.
