Abstract
Disclosed is a method of grouping transmitter-receiver pairs for communicating over a communications network. For each group of a set of groups of transmitter-receiver pairs, the pairs of the group execute an iterative interference alignment technique for I1 iterations on signals transmitted by the group. Each transmitter of the group successively sends a pilot signal that has been precoded by a matrix resulting from that execution. Each receiver of the group evaluates a metric representative of a distance between a vector subspace generated by the pilot signal transmitted by the transmitter with which it forms a pair and a vector subspace generated by interferences determined from the pilot signals transmitted by the other transmitters. A central unit calculates a global metric associated for each group on the basis of the metrics from the receivers of the group and selects from the set a group that optimizes the global metric.
