Question: What is a prerequisite for a User Equipment (UE) to support SPS repetition for subframe PUSCH on the Primary Cell (PCell)?
Option 1: Support for dynamic TDD uplink-downlink configurations.
Option 2: Support for either semi-static CFI or semi-static CFI patterns.
Option 3: Capability for transmission on multiple bands simultaneously.
Option 4: Implementation of advanced receiver types (e.g., MMSE, ZF).
Explanation: For a UE to support SPS repetition for subframe PUSCH on the PCell, it must also support either semi-static CFI configurations or semi-static CFI patterns. This ensures the UE can properly interpret and apply necessary control formats for efficient SPS operation on the primary cell.
