1. A method of video encoding, the method comprising:
partitioning a current block in a current picture into at least a first partition and a second partition based on a geometric partition mode (GPM), wherein the first partition is associated with an intra block copy (IBC) prediction mode, and wherein the second partition is associated with an intra prediction mode;
storing prediction mode information for a first subblock of a plurality of subblocks of the current block, the prediction mode information including one of a DC mode, a Planar mode, and an intra prediction mode based on whether the first subblock is associated with one of the IBC prediction mode, the intra prediction mode, and both the IBC prediction mode and the intra prediction mode; and
encoding the current block and generating coding information of the current block, the coding information indicating that the current block is partitioned into the at least the first partition and the second partition based on the GPM, and including the encoded current block and the generated coding information in a coded video bitstream.
