Question: What action does a UE (User Equipment) take with its MAC (Media Access Control) configuration when entering RRC_INACTIVE state, according to 3GPP specifications?
Option 1: The UE updates the MAC configuration with new settings received in the RRCConnectionRelease message.
Option 2: The UE keeps the current MAC configuration unchanged to maintain continuity.
Option 3: The UE resets the MAC and releases the default MAC configuration if any.
Option 4: The UE suspends the MAC operation until it exits RRC_INACTIVE state.
Explanation: When a UE enters the RRC_INACTIVE state, it performs several housekeeping tasks to manage resources efficiently. Resetting the MAC and releasing the default MAC configuration if any, ensures a clean slate for future connections, aligning with the principles of resource management in idle or low-activity states in cellular networks. This action is crucial for maintaining network efficiency and preparing the UE for potential future connections without residual configurations from previous active sessions.
