1. An apparatus of a base station in a wireless communication system, the apparatus comprising:
- a measuring unit for measuring an interference factor representing an Binterference degree by an external sector;
an estimation unit for estimating interference given to the external sector using the interference factor, an interference weight depending on a location of a terminal, and an amount of wireless resource use of a serving sector; and
a scheduler for determining a data transmission rate with consideration of an interference estimation value and a wireless channel state of the terminal

Abstract
An apparatus and a method for controlling a data transmission rate in a broadband wireless communication system are provided. In the method, an interference factor representing an interference degree by an external sector is measured. Interference given to the external sector is estimated using the interference factor, an interference weight depending on a location of a terminal, and an amount of wireless resource use of a self sector. A data transmission rate is determined with consideration of an interference estimation value and a wireless channel state of the terminal.
