Question: What is a prerequisite for a User Equipment (UE) to support the combination of Power Uncertainty Reduction (PUR) for sub-PRB when operating in Coverage Enhancement Mode A?
Option 1: The UE must support only ce-PUSCH-SubPRB-Allocation-r15.
Option 2: The UE must operate exclusively in 5G Core Network (5GC) architecture.
Option 3: The UE must also support at least one of the following: pur-CP-EPC-CE-ModeA-r16, pur-CP-5GC-CE-ModeA-r16, pur-UP-EPC-CE-ModeA-r16, or pur-UP-5GC-CE-ModeA-r16, in addition to ce-PUSCH-SubPRB-Allocation-r15.
Option 4: The UE needs to be capable of only sub-PRB allocation for uplink transmissions.
Explanation: To ensure seamless and optimized communication in Coverage Enhancement Mode A, especially when utilizing sub-PRB for more efficient resource allocation, the UE must demonstrate compatibility with specific power uncertainty reduction capabilities (PUR) tailored for either Evolved Packet Core (EPC) or 5G Core (5GC) architectures, alongside the necessary sub-PRB allocation support. This multi-faceted support ensures robust connectivity under various network conditions.
