Question: What is a prerequisite for a User Equipment (UE) to support multiple Transport Block (TB) scheduling for unicast in the downlink while operating in Coverage Enhancement Mode A?
Option 1: Support for pdsch-MultiTB-CE-ModeA-r15
Option 2: Support for ce-ModeA-r13
Option 3: Capability for Carrier Aggregation (CA) in downlink
Option 4: Implementation of Massive MIMO (Multiple Input Multiple Output)
Explanation: According to E-UTRA specifications, a UE must indicate support for ce-ModeA-r13 to support multiple TB scheduling for unicast in the downlink when operating in Coverage Enhancement Mode A, ensuring it meets necessary base requirements for enhanced coverage.
