Latency-Based 5G RAN Slicing Descriptor to Support Deterministic Industry 4.0 Applications
1 like217 views
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.
