Early in LTE, DMRS is used only in PUSCH but in NR it is introduced to use in PUCCH. Can anyone give me the use case for this .
This parameter says max no of MSG3 transmission but why this applicable only to SpCell ?
PUSCH start position says starting duration in UL symbol . But why do we have this parameter only in DCI0A/B
Does NR supports different RAT type in UL . Like RAT0 ,RAT1 etc.
