TPC-PUCCH-RNTI
Transmit Power Control PUCCH RNTI
Group RNTI used to scramble DCI Format 2_2 delivering PUCCH transmit power control commands to groups of UEs.
Technical Explanation
Similar to TPC-PUSCH-RNTI, this group identifier scrambles DCI Format 2_2 payloads carrying TPC command blocks dedicated to adjusting PUCCH transmit power for multiple UEs, regulating uplink control channel interference.
Key Functions
- Group identifier scrambling DCI Format 2_2 for PUCCH power adjustments
- Regulates multi-UE PUCCH transmit power levels simultaneously
- Protects uplink control channel reception against near-far interference
