TPC-PUSCH-RNTI
Transmit Power Control PUSCH RNTI
Group RNTI used to scramble DCI Format 2_2 broadcasting PUSCH power control commands to a group of UEs.
Technical Explanation
TPC-PUSCH-RNTI allows the gNodeB to deliver transmit power adjustments to multiple UEs simultaneously inside a single DCI Format 2_2 payload without requiring individual unicast scheduling grants, minimizing downlink control channel overhead.
Key Functions
- Group identifier for broadcasting multi-UE PUSCH power control commands
- Scrambles DCI Format 2_2 containing array of 2-bit TPC commands
- Reduces PDCCH control overhead for uplink power regulation
