Question: In Multiple Transmit/Receive Point (multi-TRP) operation, what is the main difference between single-DCI and multi-DCI modes for scheduling multi-TRP PDSCH transmissions?
Option 1: The number of TRPs used for transmission
Option 2: The type of control layer used for uplink and downlink operation
Option 3: Whether the UE is scheduled by the same DCI or independent DCIs from each TRP
Option 4: The frequency band used for transmission
Explanation: In single-DCI mode, the UE is scheduled by the same DCI for both TRPs, whereas in multi-DCI mode, the UE is scheduled by independent DCIs from each TRP. This difference allows for more flexibility and control in managing multiple TRPs in a cell.
