Downlink Control Information (DCI) carries information from gNB-to-UE such as info DL/UL resource scheduling, power control, modulation and coding schemes to decode a message, HARQ related aspects etc.
A DCI is carried as a payload within Physical Downlink Control Channel (PDCCH). PDCCH is itself wrapped inside something known as Control Set (CORESET).
I have some questions that I hope someone can explain.
How is creating a data source for DCI done so that when performing DL-SCH decoding there is no error? How is the relationship between the DCI data source and the SIB1 allocation position in the PDSCH shown?
