Apparatus and method for receiving a signal in a communication system

A method for receiving a signal in a signal receiver, comprising:

• receiving, from a serving base station, first MAP information including information related to a first modulation scheme applied to a frequency domain in the serving base station;
• receiving, from at least one neighbor base station, second MAP information including information related to a second modulation scheme applied to the frequency domain in the at least one neighbor base station;
• receiving a data burst comprising traffic data and a pilot signal in the frequency domain;
• generating channel state information by estimating the pilot signal;
• and
• determining whether to use interference cancellation using the channel state information, the first modulation scheme information and the second modulation scheme information.

An apparatus for receiving a signal in a communication system, comprising:

• a demodulator for receiving, from a serving base station, information related to a first modulation scheme applied to a frequency domain in the serving base station, receiving, from at least one neighbor base station, information related to a second modulation scheme applied to the frequency domain in the at least one neighbor base station, and receiving a signal in the frequency domain;
• a channel estimator for generating channel state information by estimating the received signal;
• and
• a selector for selecting whether to use interference cancellation using the channel state information, the first modulation scheme information and the second modulation scheme information.
