SL-RNTI
Sidelink RNTI
RNTI used by the gNodeB to schedule direct vehicle-to-vehicle V2X transmissions on the PC5 interface.
Technical Explanation
In C-V2X Sidelink Mode 1, the gNodeB controls sidelink allocations. The UE monitors PDCCH using its assigned SL-RNTI for DCI Format 3_0, which specifies the time-frequency resources and MCS to use for direct transmission on PSCCH and PSSCH.
Key Functions
- Allocated to vehicles operating in network-scheduled Sidelink Mode 1
- Scrambles DCI Format 3_0 providing PC5 sidelink transmission grants
- Enables base station coordination of automotive safety traffic
