1. A method of processing video data, further comprising:
determining a valid splitting type for a current video block from candidates of splitting types;
determining whether or how to signal a splitting type to be used for the current video block based on a determination of the valid splitting type; and
performing a conversion between the current video block and a bitstream of the current video block in accordance with results of the determining,
wherein the candidates of the splitting types at least include unsymmetrical quad-trees (UQTs) splitting, and
wherein, in the unsymmetrical quad-Trees (UQTs) splitting, the current video block is unsymmetrically split into four partitions, and at least one of the four partitions has a block size different from block sizes of other partitions of the four partitions,
wherein, when only one kind of UQT splitting is valid and UQT splitting is signaled to be used, refraining from signaling further information to indicate which kind of UQT splitting is used,
wherein, when only two kinds of UQT splitting are valid and UQT splitting is signaled to be used, signaling a flag to indicate which kind of UQT splitting is used, and
wherein, when only three kinds of UQT splitting are valid and UQT splitting is signaled to be used, signaling a message to indicate which kind of UQT splitting is used.
