Configured Scheduling RNTI
16-bit RNTI assigned to a UE used to dynamically activate, deactivate, or retransmit Semi-Persistent Scheduling.

CS-RNTI is allocated via RRC dedicated signaling. It is used to scramble PDCCH DCIs that activate or release downlink Semi-Persistent Scheduling (SPS) or uplink Configured Grant Type 2 resources. It also scrambles grants for retransmissions of configured grant packets.
Key Functions
- Activates and releases Semi-Persistent Scheduling (SPS) resources
- Controls Configured Grant Type 2 periodic uplink allocations
- Schedules dynamic retransmissions for configured grant packets
