1. A method for decoding a motion vector, the method comprising:
obtaining a motion vector predictor of a current block and a residual motion vector of the current block;
obtaining a shift-value for the residual motion vector, the shift-value corresponding to a resolution of the residual motion vector of the current block;
up-scaling the residual motion vector by performing left-shift using the shift-value; and
reconstructing a motion vector of the current block based on the up-scaled residual motion vector and the motion vector predictor,
wherein the shift-value is one of integer values including a shift-value equal to 0 and at least one shift-value greater than 0,
wherein the current block is obtained by splitting an upper block.
