Question: What is a prerequisite for a User Equipment (UE) to support sub-PRB resource allocation for Physical Uplink Shared Channel (PUSCH) in coverage enhancement mode A or B?
Option 1: Support for LTE Advanced Pro
Option 2: Capability for Carrier Aggregation
Option 3: Implementation of Massive MIMO
Option 4: Indication of support for ce-ModeA-r13
Explanation: For a UE to support sub-PRB resource allocation for PUSCH in coverage enhancement modes A or B, it must indicate support for coverage enhancement mode A (ce-ModeA-r13), ensuring proper utilization of enhanced capabilities for improved coverage.
