Abstract: A method for controlling base stations in a wireless communication system may include: performing a monitoring operation on a first base station forming a first cell in a predetermined communication area; determining whether the first base station needs to be replaced; when the first base station needs to be replaced, controlling a second base station to move in a direction of the first base station and form a second cell; when coverages of the first and second cells overlap fully or partially, decreasing a transmit power of the first base station and increasing a transmit power of the second base station; and in response to identifying that all of one or more communication nodes connected to the first cell are handed over to the second base station, determining that the first base station is successfully replaced with the second base station.

Abstract: Disclosed are a method and an apparatus for enhanced conditional handover (CHO). An operation method of a base station may comprise: receiving a measurement report message from a terminal; transmitting a CHO request message to one or more candidate target cells; receiving a CHO request ACK message from the one or more candidate target cells; and transmitting an RRC reconfiguration message including CHO status report configuration information to the terminal, wherein the CHO status report configuration information requests transmission of information for determining a target cell to which terminal is likely to be handed over among the one or more candidate target cells.
