Use of mmW bands

- Cellular mmW communications

(pref < 28 GHz – BW > 1 GHz)- Beam track problem reduced

speeds < 30 km/h

- ISD < 200m

- Preference on LoS conditions

high degradation for NLoS cell

edge users

- Wireless Backhaul (up to 73 GHz)- Nomadic nodes

- Wireless relays

- LoS/Near LoS conditions

- Increased latency

Workshop on millimetre-wave Technology for High-speed Broadband Wireless Networks, Nov 20th 2015, Page 8

mmW Communication

› Ambition

- Use new spectrum

- Minimum-size of massive MIMO antennas

- Use for backhaul, D2D, indoor and also cellular (less than 200 m)

- Use of higher order beamforming to compensate for additional losses

› Challenges

- HW limitations (antenna design, radio capabilities, space)

- Hardware impairments

- Use of real-time techniques that operate with mobility (not fixed and optimized pointing)

- Inclusion and integration of new bands as extension carriers

- Out-to-in problems

- Regulatory problems

Workshop on millimetre-wave Technology for High-speed Broadband Wireless Networks, Nov 20th 2015, Page 9

Massive MIMO

› Ambition

- Enormous enhancements in spectral efficiency without the need for increased BS densification

- Smooth channel responses thanks to the law of large numbers

- Simple transmit/receive structures simple linear transceivers, even plain single user beamforming,

perform close-to-optimally

› Challenges

- Channel estimation, since training for a big number of antennas causes delay and pilot contamination

- Architectural and algorithmical problems, due to the size of this solution

- Coexistence with small cells and mmW

- 2D antenna problems in beamforming design

Workshop on 5G RAN Design at ICC 2016Paper submission deadline: Dec 4th 2015

A workshop jointly organizedby the 5G-PPP projects:

International Workshop on 5G RAN Designin conjunction with IEEE ICC 2016, May 23 – 27 2016, Kuala Lumpur, Malaysia

Workshop topics:

• Physical layer concepts related to 5G, as for instance

• waveforms, synchronization, numerology, unified frame structure concepts

• means to obtain ultra-low latency and ultra-high reliability

• native support of D2D, V2X, broadcast and multi-cast

• low-complexity massive MIMO solutions and related enablers

• solutions for contention-based access and back-/fronthauling aspects

• MAC, RLC, PDCP and RRC concepts, in particular related to a an efficient integration of multiple

novel 5G air interfaces among each other, and with evolved legacy technology. Examples:

• Novel resource management concepts, tailored to the support of a wider range of service and

QoS requirements and novel communication forms such as D2D

• Novel initial access and mobility concepts, in particular in the context of the integration and co-

location of multiple novel and legacy air interface in 5G

• Novel multi-connectivity approaches and related system enablers

• General considerations on the control and user plane design in 5G RAN

Important Dates:

Submission deadline: December 4, 2015

Acceptance notification: February 21, 2016

Final workshop papers due: March 13, 2016

Workshop Chairs:
