•  Lower system impact from few heavy users •  Reduce the discrepancies between cell-‐edge and cell center performances

either via densifica7on or in limi7ng the interferences based on LTE/LTE-‐A interface

•  Main technologies: CoMP, Advanced receiver, Relay enhanced cells

QoE & Fairness for user throughput


DOCOMO’s Phantom cell concept

•  Utilizes system concept comprised of two overlaid NWs: –  Umbrella Network: comprised of Control Plane BS

•  Operate in currently existing frequency bands (e.g., 2 GHz) •  Use currently standardized systems (e.g., LTE) and guarantee

backwards compatibility for legacy MSs –  Detached Cell Network (DCN): comprised of several User Plane

BSs •  Operating in different (higher) frequency bands (e.g., 3.5 GHz). •  Each U-plane BS is connected to the C-plane BS through a backhaul link

Macro cell

Smaller Cell

Umbrella Network (UNW)

Detached Cell Network (DCN)

Backhaul Link



Intelligent network with low cost & high robustness

• Flexible and cost-efficient NW deployments –  Increased capacity per NW cost

–  Efficient utilization of higher and wider frequency spectrum bands –  Efficient support of different types of backhaul –  Efficient support for diverse environments

e.g., wide area and local area

• Energy/battery saving –  NW energy saving & UE battery saving

•  FRA requirements and evolu7on paths

•  M2M & Grand Societal Challenges

Outline


Grand Societal Challenges

•  The “Environment and Energy Efficiency” Challenge •  Monitoring environmental parameters, and providing the

means to have alarms; Efficient resources management; Technology waste.

•  The “Health and Demographic Change” Challenge •  Future wireless diagnostic and disease management

systems; hospital consultation and emergency scenarios; assistive technologies; well being and personalisation.

•  The “Transport” Challenge •  Urban and road traffic control; efficient trip

management; vehicle-to-vehicle and vehicle-to-infrastructure communications; the mobile office.

•  The “Food” Challenge •  Food security, sustainable agriculture, marine and

maritime research and the bio-economy
