ess of the category of mobile. The 0-1 format is used to transmit the entire configuration for specific terminals. The DCI format 1-0 introduces the allocation of resources in the physical PDSCH channel, or information relating to random access, paging and MIB system information. The size of the DCI format 1-0 (fallback format) is limited and concerns all 5G terminals by default. The informational data is limited to the common characteristics for the allocation of PDSCH resources. The DCI format 1-1 introduces the allocation of all resources concerning the physical PDSCH channel. The size of the DCI message depends on the complete configurations (aggregation of carriers, etc.). The DCI format 2-0 introduces dynamic allocation for a set of terminals by configuring the direction of the SFI slots. The DCI format 2-1 introduces a dynamic preemption of a resource initially allocated to the mobile and preempted following an interruption for a priority mobile. The DCI formats 2-2 and 2-3 are used for power control of the PUSCH/PUCCH and SRS channels respectively.

Radio identifier associated with the DCI format NG-RAN and 5G-NR The search space is indicated by a set of contiguous CCEs. The UE monitored search space to decode DCI scrambled with RNTI and read PDCCH. DCI carried scheduling assignments/grants relating to a certain component carrier. A blind search is performed when the UE mobile does not have all of the information. The CSS (Common Search Space) defines the set of DCI
