Claim 0:
1. A method for video decoding in a video decoder, comprising:
receiving prediction information of a plurality of blocks in a current picture from a coded video bitstream;
determining, based on the prediction information, that at least one of a decoder-side motion vector refinement (DMVR) mode or a bi-directional optical flow (BDOF) mode is allowed for the plurality of blocks;
in response to the determination that the at least one of the DMVR mode or the BDOF mode is allowed for the plurality of blocks, determining that a plurality of merge with motion vector difference (MMVD) merge flags is inferred as false to indicate that an MMVD mode is not applied for the plurality of blocks; and
in response to the determination that the plurality of MMVD merge flags is inferred as false for the plurality of blocks, reconstructing each block in the plurality of blocks without applying the MMVD mode.
