The DMRS for PUSCH are transmitted in the fourth symbol, (third symbol for extended CP) in a PUSCH slot and the RS sequence length equals the number of allocated subcarriers (12).The short PUCCH format of up to two UCI bits is based on sequence selection, while the short PUCCH format of more than two UCI bits frequency multiplexes UCI and DMRS. The long PUCCH formats time-multiplex the UCI and DMRS. Frequency hopping is supported for long PUCCH formats and for short PUCCH formats of duration of 2 symbols. 5G NR uses below synchronization signals: Primary Synchronization Signal, PSS, with 3 different code sequences. Secondary Synchronization Signal, SSS, with 336 different code sequences. These signals enable the UE to find a cell along with helping it in synchronizing to the cell's timing. There can be 1008 (3 X 336) possible code sequences ... 5G NR PDCCH physical layer processing. • In 5G NR, PDCCH is confined to single CORESET and it is transmitted with its own DMRS.
