Question: What is a prerequisite for a User Equipment (UE) to support flexible starting PRB for PDSCH in RRC_CONNECTED when operating in Coverage Enhancement Mode A?
Option 1: Support for LTE Advanced Pro
Option 2: Capability for Dynamic Spectrum Sharing
Option 3: Activation of Carrier Aggregation
Option 4: Indication of support for ce-ModeA-r13
Explanation: For a UE to support flexible starting PRB for PDSCH in RRC_CONNECTED when operating in Coverage Enhancement Mode A, it must indicate support for ce-ModeA-r13, ensuring alignment with physical layer procedures and channel modulation for enhanced coverage scenarios.
