4. Requirements and key performance indicators
• Availability: Availability is defined as the percentage of users or communication links
for which the Quality of Experience (QoE) requirements are fulfilled within a certain
geographical area.
• Connection density: Connection density is defined as the number of simultaneous active
devices or users in the considered area during a predefined time span divided by the area
size.
• Cost: Cost typically arises from infrastructure, end-user equipment and spectrum
licenses. A simple model could be based on the assumption that the total cost of
ownership for an operator is proportional to the number of infrastructure nodes, the
number of end-user devices and the spectrum.

5. Cont.,
• Energy consumption: Energy consumption is typically defined as energy per information bit.
• Experienced user throughput: Experienced user throughput is defined as the total amount of
data traffic.
• Latency: It is the latency of the data traffic on the MAC layer of the radio interface.Two
definitions are relevant: One-Trip Time (OTT) latency and Round-Trip Time (RTT) latency.
• Reliability: Reliability is generally defined as the probability that a certain amount of data has
been successfully transmitted
• Security: The security of a certain communication taking place is very difficult to measure
• Traffic volume density: The traffic volume density is defined as the total amount of traffic
exchanged by all devices in the considered area during a predefined time span divided by the area
size.

6. 5G system concept
• The generic 5G communication services include functions that are service-
specific, and the main enablers include functions that are common to more
than one generic 5G service.
• The three generic 5G services are:
• Extreme Mobile BroadBand
• Massive Machine-Type Communication
• Ultra-reliable Machine-Type Communication

8. Extreme mobile broadband
• Access to new spectrum and new types of spectrum access
• New radio interface for dense deployments
• Spectral efficiency and advanced antenna systems
• Number of users
• User mobility
• Links to the main enablers

9. Massive Machine-Type Communication
(mMTC)
(a) direct network access (MTC-D), (b) access via an aggregation node (MTC-A) and (c) short-range D2D access for mMTC devices
(MTC-M).

10. Dynamic radio access network
• Ultra-dense networks
• Moving Networks
• Antenna beams
• Wireless devices as temporary network nodes
• Device-to-device communication
• Activation and deactivation of nodes
• Interference identification and mitigation
• Mobility management
• Wireless backhaul
