Abstract: A method of determining a serving sub-cell of a terminal among a plurality of sub-cells by a base station in a wireless communication system is provided. The method includes generating reference signal transmission interval information for each of the sub-cells by configuring a reference signal transmission interval for each of the plurality of sub-cells, and transmitting the reference signal transmission interval information for each of the sub-cells to the corresponding sub-cell, receiving channel status information for at least one sub-cell among the plurality of sub-cells from the terminal, and determining a serving sub-cell of the terminal by using at least one of the reference signal transmission interval information, the channel status information, a reception time of the channel status information, of each of the sub-cells.
