It’s true that beamforming itself is not new (there’s actually been rudimentary beamforming since 2G). But beams are getting small and targeted enough to support space division multiple access (same frequency can be used for many mobile stations in different locations). Also, 5G mobile stations themselves support beamforming, which is important for uplink bandwidth and power usage.
