SpletIt is for scheduling physical resources for Downlink (PDSCH) and Uplink (PUSCH) Types of DCIs : 0_0, 0_1,1_0,1_1,2_0,2_1,2_2,2_2,2_3,2_4,2_5,2_6,3_0,3_1 Most Commonly Used Types : 1_0,1_1 for DL Schduling and 0_0,0_1 for UL Scheduling How UE can figure out which DCI it should decode ? : By checking RNTI masking the DCI SpletThe eNodeB determines a PDCCH format to be transmitted to the UE, creates an appropriate DCI and attaches a CRC. The CRC is then masked with an RNTI according to the owner or usage of PDCCH. If the PDCCH is for a specific UE, the CRC will be masked with a UE unique identifier, for example a Cell-RNTI (C-RNTI).
