For setting cooperation parameters of a communication system including a plurality of node devices interconnected by links and adapted to be respectively configured according to said cooperation parameters, a cooperation phase comprises: gathering measurements data representative of measurements of the random variables; optimizing the figure of merit for determining said cooperation parameters, on the basis of the obtained measurements. At least one link implying quantization operations relying on a codebook for gathering said measurements data and/or for providing said cooperation parameters, a pre-processing phase comprises beforehand: obtaining statistics data relative to a probability distribution of said random variables; and determining every codebook on the basis of the figure of merit, such that the figure of merit is statistically optimized according to the obtained statistics.
