METIS Projects
The overall goal of the METIS project is to lay the foundation for the beyond 2020 5G mobile and wireless system by
providing the technical enablers needed to address the requirements foreseen for this time frame.
This project define broad use case scenario which cover different user experience such as Amazingly fast, Great service
in a crowd, Ubiquitous things communicating, Best experience follows you and Super real-time and reliable
connections. These scenarios bring the different challenges such as Very high data rate, Very dense crowds of users,
Very dense crowds of users, Very low energy, cost, and a massive number of devices and high mobility. These
challenges are leading towards defining few KPIs on the next generation, which are explained in details below.
4.1.1
Traffic volume density
Definition: The traffic volume density describes the total user data volume transferred to/from end-user devices during
a predefined time span divided by the area size covered by the radio nodes belonging to the RAN(s). For multi-hop
solutions each user data is only counted once.
METIS-R1: This KPI is directly related to the METIS goal to support a 1000 times higher traffic volume density than
today’s networks.
4.1.2
Experienced user throughput
Definition: The experienced user throughput is the data throughput an end-user device achieves on the MAC layer (user
plane only) averaged during a predefined time span. This metric is one possible measure for the quality of experience
(QoE) level a user experiences for the service applied. However, the data rate of the service application itself is lower
than the experienced user throughput as additional protocol overhead and/or traffic control on higher layers, e.g. PDCP
and RLC at LTE, IP, TCP/UDP/SCTP). The experienced user throughput depends on the test case environment, but also
on the number of users and the amount of data they generate, because they affect the cell load and interference from
surrounding cells in a radio network.
METIS-R2: The KPI is directly related to the METIS goal to achieve a 10 to 100 times higher typical user data rate.
4.1.3
Latency
Definition: Different types of latency are relevant for different application. Eg: end to end latency or on-trip-time
(OTT) latency refer from when a data packet is sent from the transmitting end to when it is received or the receiving
end. Another latency measure is the round trip time (RTT) latency which refers to the time from when a data packet is
sent from the transmitting until acknowledgements are received from the receiving entity, e.g. internet server or other
device. The measurement reference in both cases is the MAC layer. Any processing time on higher layers, e.g. for audio
and video encoding and decoding, on the application layer, is not considered here. The entire network (radio, core, and
backhaul/aggregation) typically affects the latency, although this is test case dependent. Only the user data plane is
considered in the evaluation.
METIS-R3: The KPI is directly related to the METIS goal to provide a 5 times reduced E2E latency.
4.1.4
Reliability
Definition: Reliability is an assessment criteria to define the quality of a radio link connection fulfilling certain service
level.
METIS-R4: The KPI is important for all considered scenarios, but main challenge is seen in “Super real-time and
reliable connections”, where very high reliable values are requested for safety-relevant services..

Availability and Retainability
Definition: When the reliability decreases below an acceptable level QoE, then the user may be so dissatisfied that it
may regard the service as unavailable. The availability is an assessment criterion to describe inside coverage area te
percentage of places where service provider to the end user with the user’s requested QoE level. Alternatively,
availability is defined as the percentage of communication links for which the QoE requirements are fulfilled within a
certain geographical area, e.g. in terms of reliability as defined in the above section. The latter definition is better suited
to the case of D2D communications. Retainability is a special aspect of the above, by which a service has been made
available as long as the user needs the service.
METIS-R5: The KPI is important for all considered scenarios as it will provide a measure to identify the service
availability for the end-users in the intended coverage area. Moreover, the KPI will contribute to the optimization of the
network layout.
4.1.6
Energy consumption
Definition: The definition should be applied to three different environments: component level (for hardware innovative
solutions), node level (for innovative solution in the transmitting nodes) and network level (for efficiency of the whole
network).
METIS-R6: In terms of energy efficiency it is advisable to consider LTE Rel-11 as baseline
requirements.
4.1.7
Cost
Definition: The cost refers to all the additional investments and expenses required by the new METIS solution
METIS-R7: The METIS focus is on the radio access network and therefore the costs of the core network
and service platforms are typically not included, unless otherwise stated in the test cases. The costs with
the end-user equipment may be significant too
