Question: What is a prerequisite for a User Equipment (UE) to support MPDCCH reception in the LTE control channel region when operating in Coverage Enhancement Mode A?
Option 1: The UE must also support ce-ModeA-r13.
Option 2: The UE needs to have a specific frequency band allocated for CE Mode A.
Option 3: The UE should be capable of transmitting on multiple antennas simultaneously.
Option 4: The UE has to be in idle mode to receive MPDCCH in this configuration.
Explanation: For a UE to indicate support for MPDCCH reception in LTE control channel region when in Coverage Enhancement Mode A, it must also indicate support for ce-ModeA-r13, ensuring compatibility with required coverage enhancement features for effective network communication under enhanced coverage scenarios.
