A wireless device for dual-polarization beamforming, the wireless device comprising:
- an antenna array, the antenna array comprising antenna elements of mutually orthogonal polarizations;
- and
- a baseband chain,
- wherein the antenna elements of both polarizations are operatively connected to the baseband chain, and
- wherein the antenna array further comprises a signal combiner configured to combine signals received by the antenna elements into a composite signal and to feed the composite signal to the baseband chain.
A method for dual-polarization beamforming, the method being performed by a wireless device, the wireless device comprising an antenna array, the antenna array comprising antenna elements of mutually orthogonal polarizations;
- and a baseband chain, the method comprising:
