Question: What is a prerequisite for a User Equipment (UE) to support the ce-PDSCH-PUSCH-Enhancement-r14 feature in E-UTRA, specifically for coverage enhancement mode A?
Option 1: The UE must support only modulation restriction for PDSCH.
Option 2: The UE must be capable of transmitting on multiple bands simultaneously.
Option 3: The UE must also indicate support for ce-ModeA-r13.
Option 4: The UE needs to have a minimum of four receive antennas.
Explanation: This is because a UE indicating support of ce-PDSCH-PUSCH-Enhancement-r14 must also demonstrate compatibility with ce-ModeA-r13, ensuring seamless integration of enhanced features within the existing coverage enhancement framework. This prerequisite ensures backward compatibility and a standardized implementation across UEs supporting these advanced features.
