A method of a transceiver arranged to operate in a cellular communication system comprising cells is disclosed. The method comprises receiving a transmission from a first cell; determining an interfering signal and its occupation in time and/or frequency, wherein the interfering signal comprises almost blank subframe, ABS, from a second cell, the ABS comprising resource elements, REs, comprising reference signals; determining reduced values in the received signal corresponding to the occupation in time and/or frequency of the interfering signal by reducing soft values for bits of the transmission interfered with the REs comprising the reference signals of the interfering signal; measuring a quotient between desired signal and non-desired signal of reference symbols of the received signal; forming a channel quality index, CQI, based on the measured quotient and an amount of determined reduced values; and reporting the CQI to the communication system. A transceiver and computer program for the same are also disclosed.
