The document discusses the need for network slicing in 5G networks to support the diverse communication requirements of Industry 4.0 applications. It notes that current network slicing proposals only consider data rate requirements and do not explicitly account for latency, which are critical for deterministic industrial applications. The paper then proposes using a novel slice descriptor for radio access network slicing that accounts for latency requirements in order to guarantee quality of service for periodic deterministic industrial traffic.

• Current proposals only considers data rate (or bandwidth)
requirements of the applications
– Latency requirements are not explicitly considered
– Latency requirements are critical for Industry 4.0 applications
This work proposes the use of a novel slice descriptor
that accounts for latency requirements
• QoS of deterministic periodic traffic
is always guaranteed when the novel
latency-based slice descriptor is
considered
