1. A method of video decoding, comprising:
receiving a coded bitstream carrying at least a picture that includes a block comprising a plurality of subblocks;
determining that a current coding unit (CU) in the picture is coded in a subblock based inter prediction mode based on a first syntax element value in the coded bitstream;
determining that one or more first subblocks in the current CU that is coded in the subblock based inter prediction mode are coded by intra prediction;
reconstructing one or more second subblocks of the current CU by inter prediction based on the subblock based inter prediction mode, wherein the one or more second subblocks do not overlap with the one or more first subblocks in the current CU; and
reconstructing the one or more first subblocks of the current CU by the intra prediction while the current CU is coded in the subblock based inter prediction mode.
