Question: What is a prerequisite for a User Equipment (UE) to support repetition levels 64 and 128 for PUCCH in CE Mode B, as part of the ce-PUCCH-Enhancement-r14 feature?
Option 1: The UE must also support ce-ModeB-r13.
Option 2: The UE needs to operate exclusively on TDD (Time Division Duplex) mode.
Option 3: The UE has to be capable of transmitting on all E-UTRA frequency bands.
Option 4: The UE should have a minimum of four receive antennas.
Explanation: For a UE to support ce-PUCCH-Enhancement-r14 (including repetition levels 64 and 128 for PUCCH in CE Mode B), it must also support ce-ModeB-r13, ensuring backward compatibility and adherence to defined standards for enhanced physical layer procedures in E-UTRA networks.
