SpletThe entire PDCCH payload is used to calculate a set of CRC parity bits. The PDCCH payload is divided by a cyclic generator polynomial to generate 16 parity bits. These parity bits are then appended to the end of the PDCCH payload. As multiple PDCCHs relevant to different UEs can be present in one subframe, the CRC is also used to specify to ... Splet12. apr. 2024 · The video looks at the time and frequency structure of a CORESET, and its role in downlink control information as the location of the physical downlink control channel (PDCCH). It illustrates the impact of CORESET and PDCCH parameters on the OFDM grid using an interactive example, and it discusses interleaved and non-interleaved mapping.
SpletTo form the PDCCH payload the DCI undergoes channel coding: addition of a CRC attachment followed by convolutional coding and rate matching according to PDCCH … SpletIntroduction.
