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: In a communication environment using a millimeter wave band, a method and apparatus that enable a base station to process data are provided. A protocol stack is generated based on a characteristic of traffic that is provided to a terminal, and the generated protocol stack is allocated to the terminal. Data to be provided to the terminal is processed according to the generated protocol stack, and data that is processed through a beam that is allocated based on a position vector of the terminal is transmitted.
