4 Content 5G standards and spectrum roadmap 5G/Pre-5G use cases 5G Spectrum Sharing in mm-wave bands Unlicensed sharing Licensed sharing Conclusion

5 3GPP timeplan 5 3GPP Rel-15 Scope and Schedule Scope : Above 6GHz & below 6GHz, 5G standalone followed by non-standalone 5G Phase 1 5G Phase 2 source: Qualcomm 2017

6 IMT-2020 Standardization Process Where we are and what is ahead Development Plan Market/Services View Technology/ Research Kick Off Vision & Framework Name IMT-2020 < 6 GHz Spectrum View > 6 GHz Technical View Process Optimization Spectrum/Band Arrangements (post WRC-15) Technical Performance Requirements Evaluation Criteria Invitation for Proposals Sharing Study Parameters (IMT- WRC-19) Sharing Studies (WRC-19) Proposals Evaluation Consensus Building CPM Report (IMT- WRC-19) Sharing Study Reports (WRC-19) Spectrum/Band Arrangements (WRC-19 related) Decision & Radio Framework Detailed IMT-2020 Radio Interface Specifications Future Enhancement/ Update Plan & Process Setting the stage for the future: vision, spectrum, and technology views Defining the technologies source: ITU 2017

7 Early 5G Use Case: Fixed Wireless Access gaining momentum Dr Weng Tong, Huawei IEEE Globecom Dec 2016 Verizon announced FWA trials in Five U.S. cities scheduled for second quarter of 2017, with Samsung and Cisco 7

8 Future bands to be studied by 2019 New spectrum: bands under study for WRC-19 5G Pioneer Band Existing mobile allocation No global mobile allocation GHz 27.5 GHz GHz GHz GHz GHz GHz GHz GHz GHz GHz GHz 5G NR source: ITU 2017

9 mm-wave spectrum holding by US operators (before acquisition of Straight Path by Verizon)

10 3GPP SI on spectrum sharing source: Qualcomm 2017

11 Sharing mm-wave bands Beamforming is a mandatory requirement in 5G Beam forming is mandatory in ad; both transmitside 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 2016 Samsung Electronics

12 Spectrum sharing in licensed mm-wave bands Guidolin, Nekovee, IEEE ICC 2014 Collaboration with Richard Rudd, Plum Consulting Reported at ITU-R Working Group xx, March 2017 Additional interference paths due NLOS to reflections

14 Sharing secenario in unlicensed mm-wave bands

15 Beam scheduling as enabler for unlicensed sharing (1/2) Nekovee, Qi, Wang, 2017

16 Beam scheduling as enabler for unlicensed sharing (2/2) Nekovee, Qi, Wang, 2017

17 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
