1. An image decoding method performed by an image decoding apparatus, the image decoding method comprising:
deriving a size of a subblock based on a size of a current block;
partitioning the current block into one or more subblocks based on the size of the subblock,
wherein the partitioning the current block is performed based on depth information, and
wherein the depth information indicates the number of partitioning times of the current block; and
performing inverse-transformation for the subblock,
wherein a binary tree partitioning is allowed for the current block having a width different from a height,
wherein the binary tree partitioning is not allowed for the current block having the width identical to the height, and
wherein the binary tree partitioning is representative of a division type to divide one current block into two subblocks.
