Question: In 5G New Radio (NR) Uplink, for Non-Interleaved Virtual Resource Block (VRB) to Physical Resource Block (PRB) Mapping, what determines the exception to the direct VRB-to-PRB mapping in Active Uplink Bandwidth Part?
Option 1: Scheduling by DCI Format 1_0 with CRC scrambled by C-RNTI
Option 2: Type of Subcarrier Spacing used in the Initial Uplink Bandwidth Part
Option 3: Presence of a Simultaneous PUCCH Transmission
Option 4: PUSCH Scheduled by RAR UL Grant or DCI Format 0_0 with CRC scrambled by TC-RNTI
Explanation: According to the 3GPP specifications for NR, an exception to the direct non-interleaved VRB-to-PRB mapping occurs specifically when a PUSCH (Physical Uplink Shared Channel) is scheduled either by a RAR (Random Access Response) UL Grant or by DCI (Downlink Control Information) Format 0_0 with its CRC (Cyclic Redundancy Check) scrambled by the TC-RNTI (Temporary Cell-RNTI). This specific scheduling scenario alters the typical direct mapping rule within an active uplink bandwidth part that starts at a particular resource block and has matching subcarrier spacing and cyclic prefix.
