Summary
This chapter provides an overview of the fast traffic steering and radio resource management (RRM) mechanisms envisioned for 5th generation (5G). It presents briefly the quality of service (QoS) framework for 5G networks, focusing on service classification mechanisms. The chapter focuses on the network-controlled resource allocation for scheduled unicast transmissions between the network infrastructure and user equipments (UEs). In addition to dynamic scheduling, also semi-persistent scheduling (SPS) mechanisms and various forms of grant-free scheduling are of relevance for 5G, especially for the uplink (UL) direction. The chapter considers the use of fast-timescale dynamic traffic steering between various AI variants (AIVs) within the 5G network as a key enabler of various network key performance indicators (KPIs) ranging from high-capacity to ultra-reliability. It also presents two mechanisms for the energy-efficient moderation of radio access network (RAN) nodes, which includes base stations (BSs) and related backhaul (BH) links.
