1. A method of identifying a moving cell causing interference, by a user equipment (UE) connected to a first moving cell, the method comprising:
acquiring system information of a fixed cell to which the first moving cell is connected through a backhaul interface;
obtaining, through a cell search, a physical cell identifier of a second moving cell neighboring to the first moving cell;
determining whether the second moving cell causes interference to the first moving cell based on the system information of the fixed cell and the physical cell identifier of the second moving cell; and
reporting the physical cell identifier of the second moving cell to the first moving cell, when determined that the second moving cell causes interference to the first moving cell.
