  • Patent number: 11382076
    Abstract: Some of the present implementations provide a method for a user equipment (UE) for performing a physical uplink control channel (PUCCH) repetition. The method may include receiving, from a base station, a physical downlink control channel (PDCCH) comprising downlink control information (DCI) in a control resource set (CORESET). The method then determines a spatial domain filter for a PUCCH transmission based on an index associated with the CORESET. After determining the spatial domain filter, the method may transmit, to the base station, a PUCCH in a slot using the spatial domain filter, and transmit, to the base station, a repeat of the PUCCH in one of the same slot, or a different slot, using the spatial domain filter.
