TPC-SRS-RNTI
Transmit Power Control SRS RNTI
Group RNTI used to scramble DCI Format 2_3 broadcasting power control adjustments for sounding reference signals.
Technical Explanation
TPC-SRS-RNTI scrambles DCI Format 2_3, delivering a block of 2-bit TPC commands targeting the transmit power of Sounding Reference Signals (SRS) for UEs not currently scheduled for PUSCH data transmission.
Key Functions
- Scrambles DCI Format 2_3 group power commands for Sounding Reference Signals
- Adjusts SRS transmit power independently of PUSCH/PUCCH channels
- Maintains optimal channel sounding SNR across non-scheduled UEs
