Question: In a PUSCH transmission with multiple UL-SCH transport blocks, where do you multiplex UCI information when two or more blocks have the same highest IMCS value?
Option 1: On all transport blocks with the highest IMCS value, distributing the UCI information evenly.
Option 2: Only on the first transport block among those with the highest IMCS value.
Option 3: On a round-robin basis across all transport blocks with the same highest IMCS value in successive transmissions.
Option 4: Not multiplexed; UCI is transmitted separately from data in such scenarios.
Explanation: According to the principles guiding the handling of multiple UL-SCH transport blocks in a PUSCH transmission, when there's a tie in IMCS values among these blocks, the protocol dictates that UCI (Uplink Control Information) is multiplexed with data solely on the first transport block. This approach ensures clarity and consistency in how control information is integrated with payload data during uplink transmissions, particularly in scenarios where multiple transport blocks share the same priority (as indicated by their IMCS values).
