COMMUNICATION UNIT, INTEGRATED CIRCUIT AND METHOD FOR GENERATING A PLURALITY OF SECTORED BEAMS

摘要

A communication unit comprises a plurality of antenna element feeds (203, 205) for coupling to a plurality of antenna elements of an antenna array, where each antenna element feed comprises at least one coupler; and a plurality of transmitters operably coupled to the plurality of antenna element feeds. At least one transmitter of the plurality of transmitters comprises: an input for receiving a first signal and at least one second signal; beamformer logic arranged to apply independent beamform weights (RcfBF1, RcfBF2) on the first signal and the at least one second signal of the transmitter respectively, wherein each of the independent beamform weights is allocated on a per sector basis; and a signal combiner arranged to combine the first signal and the second signal to produce a combined signal, such as that the combined signal supports a plurality of sectored beams.
