Method and device for determining channel state information

A system for determining channel state information, the system comprising:

• means for receiving a downlink signal, wherein the downlink signal comprises a transport block comprising a plurality of code blocks, each code block of the plurality of code blocks comprising a plurality of resource elements arranged according to an orthogonal frequency division multiplex configuration;
• means for determining a worst case code block of the plurality of code blocks based on a hypothesis of a transmitter-configured number of code blocks per transport block and based on at least one of noise or interference experienced by the plurality of resource elements of the respective code blocks, the means for determining the worst case code block configured to determine the worst case code block for the hypothesis of the transmitter-configured number of code blocks per transport block as the code block of the plurality of code blocks for which code block a ratio of interfered resource elements of the code block is maximum;
• and
• means for determining a metric indicative of a channel state information based on the worst case code block, the metric comprising mutual information based on an estimated signal quality of the downlink signal.

• determine a worst case code block of the plurality of code blocks based on at least one of noise or interference experienced by the plurality of resource elements of the respective code blocks, the worst case code block determined as the code block of the plurality of code blocks for which code block a ratio of interfered resource elements of the code block is maximum;
• and
• determine a metric indicative of a channel state information based on the worst case code block, the metric comprising mutual information based on an estimated signal quality of the downlink signal.
