Question: In a 5G NR (New Radio) uplink transmission, when PUSCH repetition Type B is applied to a physical channel without intra-slot frequency hopping, how can the channel for one symbol on an antenna port be inferred from another symbol on the same port?
Option 1: If the two symbols are transmitted in consecutive slots.
Option 2: If the two symbols correspond to the same actual repetition of a PUSCH transmission with repetition Type B.
Option 3: Based on the DM-RS (Demodulation Reference Signal) bundling pattern.
Option 4: If the two symbols correspond to the same slot, regardless of their position within the slot.
Explanation: According to the principles guiding uplink transmissions in 5G NR when PUSCH repetition Type B is applied without intra-slot frequency hopping, inference about the channel for one symbol from another on the same antenna port can be made if both symbols are within the **same slot**. This ensures coherence in channel estimation across the slot for effective demodulation and decoding, highlighting the importance of slot-level channel consistency in uplink transmissions.
