WebIntroduction. NR and LTE use downlink control information (DCI) to send dynamic physical layer control messages from the network to each UE. This information can be system-wide or user-equipment-specific (UE-specific), and contains aspects of uplink and downlink data scheduling, HARQ management, power control, and other signalling. … WebThe example aids understanding of the control region used in an LTE downlink subframe and its channel structure by showing how a downlink control information (DCI) message is generated and transmitted over a physical downlink control channel (PDCCH) and recovered by performing blind decoding using the LTE Toolbox™.
