The present invention relates to a method of reducing interference in a communication system supporting multiple radio channel communication scheme and wherein a communication link can be established between a transmitter and a receiver. In the method the transmitter first determines (301) interference level at the transmitter, and then based on the determined interference level, performs link adaptation, wherein the link adaptation comprises applying (307) channel bundling for adapting the communication link so as to transmit simultaneously on at least two radio channels from the transmitter to the receiver.
