ENHANCED PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) TRANSMISSION FOR HIGH RELIABILITY

Abstract:

Technology is disclosed for a user equipment (UE) operable for physical uplink control channel (PUCCH) transmission. The UE can be configured to: decode a multiple-PUCCH transmission indicator, wherein the multiple-PUCCH transmission indicator enables multiple-PUCCH transmissions from the UE via a plurality of transmission-reception points (TRPs); decode one or more PUCCH resource fields in a downlink control information (DCI); and identify from the one or more PUCCH resource fields in the DCI: one or more PUCCH resources associated with a primary TRP of the plurality of TRPs, wherein the one or more PUCCH resources associated with the primary TRP are used for hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback; or one or more PUCCH resources associated with a secondary TRP of the plurality of TRPs, wherein the one or more PUCCH resources associated with the secondary TRP are used for HARQ-ACK feedback.
