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 ... SpletThe fields defined in a format may also depend on the type of RNTI associated with the control information, for example, system information, paging, power control, and user scheduling. This RNTI value scrambles the CRC attached to the information bit payload sent on the PDCCH. The DCI formats supported by NR Release 16 are:
