1. A base station apparatus in a mobile communication system, the apparatus comprising:
a measuring unit for measuring loads of all mobile stations existing within a sector;
a first computation unit for computing a sector load by using a Rise Over Thermal (ROT) of the sector;
a second computation unit for computing an interference factor, which is a ratio of an interference load caused by an adjacent sector to a corresponding sector load, by using the load of each mobile station and the sector load; and
a determining unit for predicting a sector load depending on variation of a reverse data transfer rate of a target mobile station by using the interference factor and for determining the reverse data transfer rate of the target mobile station in a range where the predicted sector load does not exceed a sector threshold load.
