Question: What is the primary objective of the E-UTRA – NR Cell Resource Coordination procedure between an eNB (Evolved Node B) and an en-gNB (next-generation Node B)?
Option 1: To manage handovers for User Equipment (UE) moving between E-UTRA and NR cells.
Option 2: To optimize network-wide energy consumption by coordinating sleep modes of adjacent base stations.
Option 3: To facilitate the exchange of subscriber data for billing purposes across different networks.
Option 4: To coordinate radio resource allocation for data traffic in overlapping E-UTRA and NR coverage areas sharing spectrum.
Explanation: The correct answer, Option 4, aligns with the purpose outlined for the E-UTRA – NR Cell Resource Coordination procedure, which is to enable the coordination of radio resource allocation between eNB and en-gNB that share spectrum and have overlapping coverage areas. This is crucial for efficient spectrum utilization and minimizing interference in shared spectrum scenarios.
