1. A method of video decoding performed in a video decoder, the method comprising:
receiving coded information of a current block in a current picture of a video from a coded video bitstream;
partitioning the current block into a first partition and a second partition based on a geometric partition mode (GPM);
in response to determining that the current block is coded in the GPM, determining a first prediction type for the first partition of the current block and a second prediction type for the second partition of the current block based on at least one flag associated with a prediction type comprising one of intra prediction, inter prediction, and intra block copy (IBC), each of the first and second prediction types being one of the intra prediction, the inter prediction, and the IBC;
based on the determined first prediction type, determining a first prediction mode for the first partition of the current block;
based on the determined second prediction type, determining a second prediction mode for the second partition of the current block; and
reconstructing the first partition of the current block based on the first prediction mode and the second partition of the current block based on the second prediction mode.
