1. A method for performing an inter prediction, the method comprising:
determining whether merge mode is applied a current block;
deriving coding information in units of a coding block;
deriving motion information of the current block using the coding information; and
performing an inter prediction on the current block using the motion information,
wherein the current block is any one of sub blocks divided from the coding block,
wherein the coding information includes information related to merge mode,
wherein the information related to merge mode includes merge candidates, which are derived based on a position of the coding block,
wherein, when the coding block has a predefined size, the coding information is used for predicting motion information of the sub blocks divided from the coding block, and
wherein, when the coding block does not have the predefined size, merge candidates derived based on a position of each of the sub blocks are used for predicting motion information of the sub blocks.
