The 5G Medium Access Control (MAC) layer operates within Layer 2 of the 5G protocol stack and serves as the vital link between the physical layer (Layer 1) and higher protocol layers. It ensures seamless communication and resource optimization across diverse and dynamic network environments. The MAC layer’s responsibilities include:
Efficient Resource Allocation:
Dynamically assigns frequency, time, and power resources to users based on traffic demands and Quality of Service (QoS) requirements.
Employs advanced scheduling algorithms to manage the allocation of scarce radio resources effectively, ensuring both fairness and throughput.
Example: Allocating resources to high-priority users during peak hours while ensuring minimum service levels for other users.
Error Control:
Implements Hybrid Automatic Repeat Request (HARQ) to manage retransmissions of corrupted packets without introducing significant latency.
HARQ combines forward error correction (FEC) with retransmission strategies, providing reliability even in challenging network conditions.
Example: HARQ is critical for applications like video streaming, where packet loss can degrade quality.
Traffic Management:
Prioritizes traffic flows based on QoS parameters such as latency, reliability, and bandwidth requirements.

Example: Prioritizing resources for real-time gaming during peak hours while maintaining sufficient bandwidth for background downloads.
Network Slicing Support:
Allocates isolated resources to distinct network slices, enabling dedicated performance for applications like eMBB (high-speed broadband) and URLLC (low-latency services).
Example: Guaranteeing ultra-low latency for industrial IoT applications while providing high bandwidth for streaming services.
Flexible Numerology:
Supports variable subcarrier spacing (15 kHz, 30 kHz, 60 kHz, etc.) and slot durations to optimize performance across diverse applications.
Example: Using narrower subcarriers for massive IoT (mMTC) deployments to improve energy efficiency and broader subcarriers for eMBB to maximize throughput.
QoS Mapping:
Maps application-layer QoS requirements to specific MAC-layer bearers, ensuring precise traffic handling.
Example: Mapping real-time voice calls to a dedicated bearer with low latency and high reliability.
