This document discloses a solution for inter-cell interference control in a cellular communication system. A method comprises: detecting, by an access node managing an interfered cell in a cellular communication system, inter-cell interference from an interfering cell; determining whether or not interference cancellation performed for a signal received through the access node is capable of cancelling said inter-cell interference; and controlling, on a basis of a result of said determining, uplink transmit power of a terminal device on time-frequency resources allocated to the terminal device.
