| LTE DCI Format | Use Case |
|---|---|
| DCI-0 | Uplink scheduling assignment |
| DCI-1 | Downlink scheduling for 1 PDSCH codeword (SISO/SIMO modes) |
| DCI-1A | Compact version of format 1 scheduling for 1 PDSCH codeword or Dedicated preamble assignment to initiate random access |
| DCI-1B | Very compact DL scheduling for 1 PDSCH code-word used in MIMO mode No.6 |
| DCI-1C | Very compact DL scheduling for paging OR system information |
| DCI-1D | Compact DL (Downlink) scheduling for 1 PDSCH code-word including MIMO precoding+power offset information needed for Multi-User MIMO |
| DCI-2 | DL Scheduling assignment for MIMO including closed loop spatial multiplexing |
| DCI-2A | DL scheduling assignment for MIMO including open loop spatial multiplexing |
| DCI-3 | Transmit power control (TPC) information for PUCCH/PUSCH with 2-bit power adjustment value |
| DCI-3A | TPC information for PUCCH/PUSCH with 1-bit power adjustment |
