When UE decodes the DCI Format 1_0 with CRC scrambled by C-RNTI and the “ Frequency domain resource assignment ” field are of all ones, the DCI format 1_0 is for random access procedure … Splettransmission then it can deduce that the UE failed to receive the PDCCH. A set of 24 CRC bits are calculated from the PDCCH payload. These CRC bits are scrambled using the relevant RNTI. Scrambling changes some bits from ‘1’ to ‘0’ and other bits from ‘0’ to ‘1’. The order of the bits is not changed. Channel coding is applied ...
