It carries information such as scheduling information and resource grant to one or multiple UEs. DCI contains following information encapsulated in different formats given below - Format 0 — for transmission of uplink shared channel (UL-SCH) allocation Format 1 — for transmission of DL-SCH allocation for Single Input Multiple Output (SIMO) Format 1A — allocating a dedicated preamble signature to a UE for random access Format 1B — for transmission control information of multiple-input multiple-output (MIMO) rank-1 Format 1C — for very compact transmission of PDSCH assignment Format 2/2A— for transmission of DL-SCH allocation for closed and open loop MIMO respectively Format 2C/2D - for the scheduling of up to 8-layer transmission Format 3/3A — for transmission of TPC command for an uplink channel In one subframe, multiple UE’s can be scheduled. Therefore, multiple DCI messages can be sent using multiple PDCCH’s.
