1. A method of video encoding, comprising:
determining a block vector of a current block that is to be coded in intra block copy (IBC) mode, the block vector pointing to a first reference block of the current block in a current picture;
performing an operation on at least one component of the block vector based on the first reference block being outside a search range of the current block, the block vector being modified by the operation to point to a second reference block that is within the search range for the current block; and
encoding the current block based on the modified block vector,
wherein the performing the operation includes performing a modulo operation on a y component of the block vector based on a size of a current coding tree unit (CTU) that includes the current block.
