CCE index is used to inform about the location of PDCCH information within the control symbols, I meant to say starting 2 or 3 OFDM symbols of each subframe.
DAI is used by eNodeB to ask UE to report DL HARQ-ACK for the configured number of subframes using PUCCH/PUSCH.
This is my basic understanding of these two terms.
