Question: What is facilitated by the introduction of specific mechanisms in the 3GPP NR and NG-RAN Overall description?
Option 1: Ultra-Reliable and Low Latency Communications (URLLC) services
Option 2: High-Speed Data Transfer services
Option 3: Enhanced Mobile Broadband (eMBB) services
Option 4: Machine-Type Communications (MTC) services
Explanation: The introduction of specific mechanisms in the 3GPP NR and NG-RAN Overall description facilitates the support of Ultra-Reliable and Low Latency Communications (URLLC) services. This is because these mechanisms enable features such as more frequent Scheduling Request (SR) opportunities, which are essential for URLLC services that require low latency and high reliability.
