SpletGenerate PDCCH bits. The encoded DCI messages are then assigned to CCEs, as discussed in Matching PDCCHs to CCE Positions. The capacity of the control region depends on the bandwidth, the CFI, the number of antenna ports and the HICH groups. You can calculate the total number of resources available for PDCCH by using the ltePDCCHInfo function.
