In another variant, interference suppression may even be applied in cases where the CIR is time-variant. In such a context, the CIR used for interference suppression may not exactly coincide with the actual CIR (with the difference between the two becoming larger over time). Even if there is a difference between the CIR used for interference suppression purposes and the actual CIR, the results of the interference suppression may still improve the communication considerably (even though below the full potential of the technique). At the very least, the interference suppression may be applied starting from the moment the CIR is exchanged between the various BS (it is assumed that the actual CIR is perfectly known to all relevant BS at that stage), and the point where the correlation between the two CIRs (i.e., CIR used for interference suppression and the actual CIR) is so low that the interference suppression introduces additional interference compared to the suppressed interference for the target UE (i.e., adds no further value, but actually begins to detract).

Scheduling Preambles and Learning Sequences—

In another aspect of the present invention, the preambles 402 and learning sequences 404 occupying all or larger parts of the spectrum (in comparison to pilot tones which are distributed over time-frequency resources 108), can be likewise pre-coded. Learning sequences 404 and preambles 402 are also typically predefined sequences which can be known a priori at neighboring BS without requiring an undue amount of inter-BS-signaling. Moreover, the interference reduction achieved by shifting the preamble and CIR learning sequence is greater than that achievable with pilot tone-based interference cancellation as previously described, since a larger part of the interfering signal is known a priori to neighboring base stations.
