• Beamforming is a mandatory requirement in 5G – Beam forming is mandatory in 802.11ad; both transmit-
side and receive-side beamforming are supported
– 5G NR specification on beamforming are being finalized (non-standalone followed by stand-alone)
• A new “dimension” for sharing spectrum– Potential for much better spatial reuse than 4G
(from 2D to1D)
– New interference scenarios due to “beam-collision” and mm-wave channel characteristics

Conclusions
• Race for mm-wave spectrum is ongoing in USA and likely to intensify elsewhere as 5G progresses
• mm-wave bands offer new opportunities for spectrum sharing, complimentary to exclusive licensing
• Sussex is already contributing with better channel models & novel sharing protocols (ITU-R, 5G PPP, 3GPP) (industry-focused research)
Delighted to discuss new collaborations with industry, SME, universities in 5G (RF, spectrum, protocols, verticals) and beyond
