Determination of channel condition indication

A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising program instructions, the computer program being loadable into a data-processing unit of a wireless communication device and configured to cause, when the computer program is run by the data-processing unit, the wireless communication device to, when operating in connection with a cellular communication system providing a serving cell operated by a network node of the cellular communication system and one or more interfering cells:

• receive a signal comprising symbols of the serving cell transmitted in a downlink channel and symbols of the one or more interfering cells;
• calculate a first function of a signal-to-interference ratio of the received signal;
• select one or more of the interfering cells as dominant interfering cells based on a respective average power of reference symbols of the one or more interfering cells in the received signal;
• determine an average power of demodulated symbols of the serving cell in the received signal;
• determine a respective average power of demodulated symbols of each of the dominant interfering cells in the received signal;
• calculate a metric value based on the average power of demodulated symbols of the serving cell and on the respective average power of demodulated symbols of each of the dominant interfering cells;
• determine a channel condition indication based on the metric value and the first function of the signal-to-interference ratio of the received signal;
• and
• transmit the channel condition indication to the network node, thereby providing downlink channel condition information to a network node.

An arrangement of a wireless communication device operating in connection with a cellular communication system providing a serving cell operated by a network node of the cellular communication system and one or more interfering cells, the arrangement comprising:

• programmable hardware or one or more application-specific integrated circuits, or a combination thereof, configured to
• calculate a first function of a signal-to-interference ratio of a received signal comprising symbols of the serving cell transmitted in a downlink channel and symbols of the one or more interfering cells;
• select one or more of the interfering cells as dominant interfering cells based on a respective average power of reference symbols of the one or more interfering cells in the received signal;
• determine an average power of demodulated symbols of the serving cell in the received signal and a respective average power of demodulated symbols of each of the dominant interfering cells in the received signal;
• calculate a metric value based on the average power of demodulated symbols of the serving cell and on the respective average power of demodulated symbols of each of the dominant interfering cells;
• and
• determine a channel condition indication based on the metric value and the first function of the signal-to-interference ratio of the received signal.
