Session 02/09 : 5G Mini Slots & Preemptive Scheduling : For Ultra-Low Latency Use-Cases

Views 1

In this video, we dive deep into how 5G achieves ultra-low latency, making it a game-changer for real-time applications like autonomous vehicles, industrial IoT, and mission-critical communications. The introduction of mini-slots, preemptive scheduling, and self-contained slots brings unparalleled flexibility to 5G networks.

We’ll explore:
* Mini-Slots: A shortened version of traditional slots that reduces wait times, allowing data transmission without waiting for slot boundaries. Mini-slots can start at any symbol boundary, making data scheduling more dynamic.
* Preemptive Scheduling: Learn how 5G schedules high-priority traffic (like URLLC) by "stealing" resources from ongoing lower-priority traffic. This ensures that latency-sensitive data gets through without delay.
* Self-Contained Slots: Understand how self-contained slots in 5G allow complete downlink transmission, acknowledgment, and uplink response within a single slot, reducing latency to as low as 500 microseconds.
* Subcarrier Spacing: Discover how the flexible subcarrier spacing in 5G allows different slot durations depending on the use case, helping optimize for both latency and throughput.
* Trade-Offs: We’ll also discuss the trade-off between latency and power efficiency. With 5G’s mini-slots and preemptive scheduling, low-latency devices often need to stay active, consuming more power.


Whether you're working in telecom or simply interested in how 5G technology supports low-latency applications, this video is for you. Understand how these advanced features pave the way for future technologies like smart cities, remote surgery, industrial automation, and real-time communication.
