Question: What is a prerequisite for a User Equipment (UE) to support MPDCCH performance improvement with precoder cycling in coverage enhancement mode B, as per E-UTRA specifications?
Option 1: The UE must operate exclusively in TDD (Time Division Duplexing) mode.
Option 2: The UE needs to support only the most recent LTE (Long-Term Evolution) releases.
Option 3: The UE must also indicate support for ce-ModeB-r13 (coverage enhancement Mode B, release 13).
Option 4: The UE has to be capable of transmitting on all available frequency bands simultaneously.
Explanation: According to E-UTRA specifications, for a UE to support MPDCCH (Multicast Channel) performance improvement with precoder cycling in coverage enhancement mode B, it is mandatory that the UE also supports ce-ModeB-r13. This ensures backward compatibility and adherence to standardized protocols for enhanced coverage scenarios, highlighting the importance of incremental capability support in telecom standards.
