Overlapping cells for wireless coverage

摘要

A system is provided for overlapping cells for wireless coverage in a cellular communication system. The system includes a beam-weight generator and beamformer coupled to the beam-weight generator. The beam-weight generator is configured to generate a plurality of beam weights including at least first and second sets of beam weights. And the beamformer is configured to apply the first and second sets of beam weights to signals in a cellular communication system. The cellular communication system provides coverage over a geographic region divided into cells arranged in overlapping first and second layers of cells having criteria optimized for communication by respective, distinct first and second types of user terminals. In this regard, the criteria are reflected in the first and second sets of beam weights, such that the first and second sets of beam weights adapt the signals according to the criteria of the first and second layers of cells, respectively.
