Abstract: A UE configured for operation in a 5G NR network may decode RRC signalling from a generation gNB that includes a PUCCH-Config IE to configure the UE with a number of slots for PUCCH repetition. The UE may decode a DCI format scheduling dynamic PUCCH repetition per PUCCH resource when the DCI format indicates a PUCCH resource for the PUCCH repetition. The PUCCH resource may include a repetition number of slot and may be indicated by the DCI format comprising a starting symbol index and a number of symbols for repetition of the PUCCH within each of the slots of the number of slots. If the DCI indicates the PUCCH resource that includes the repetition number of slots, the DCI format schedules dynamic PUCCH repetition and the UE repeats the scheduled PUCCH transmission in accordance with the repetition number of slots per the PUCCH resource indicated by the DCI format, otherwise, the UE repeats the scheduled PUCCH transmission in accordance with a repetition number indicated by the PUCCH-Config IE.
