1. A method of processing video data, comprising:
determining, for a conversion between a current video block of a video and a bitstream of the video, whether a partitioning scheme is allowed for the current video block according to a rule that depends on a mode type of the current video block and a dimension of the current video block; and
performing the conversion based on the determining;
wherein the partitioning scheme comprises:
a QT (quaternary tree) split in which the current video block is split into four parts in both horizontal and vertical directions,
a vertical TT (ternary tree) split in which the current video block is split into three parts in a vertical direction,
a horizontal TT split in which the current video block is split into three parts in a horizontal direction,
a vertical BT (binary tree) split in which the current video block is split into two parts in a vertical direction, or
a horizontal BT split in which the current video block is split into two parts in a horizontal direction.
