    Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

    Abstract: PUCCH carrier switching includes decoding an RRC configuration that indicates a reference cell having a reference cell slot numerology. A reference cell slot is determined for PUCCH transmissions based on the reference cell slot numerology. The determined slot is used for transmission of an SR, CSI, or HARQ-ACK, A DCI indicating a candidate target PUCCH cell having a candidate target PUCCH cell slot numerology and a slot of the candidate target PUCCH cell is decoded. A target PUCCH cell having a target PUCCH cell slot numerology is determined for transmitting the SR, the CSI, or the HARQ-ACK. The determined slot is mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource is determined for transmitting the SR, the CSI, or the HARQ-ACK using the corresponding slot of the target PUCCH cell. The PUCCH resource determination is based on a PUCCH configuration of the target PUCCH cell.
