A method, performed by a network node in a radio access network, RAN, for power control of user equipment, UE, uplink, UL, transmissions that are associated with a plurality of data services having different reliability requirements, the method comprising: configuring the UE with a plurality of resources that can be allocated for UL transmissions based on one or more transmit power control, TPC, parameters, wherein the plurality of resources include: first resources associated with first parameter values for the respective TPC parameters, and second resources associated with second parameter values for the respective TPC parameters, wherein the first parameter values provide increased UL transmission reliability relative to the second parameter values; transmitting, to a UE, a downlink, DL, control message comprising: an indication that the first resources or the second resources are allocated for an UL transmission of a hybrid-ARQ acknowledgement, HARQ-ACK, on a physical uplink control channel, PUCCH, the UL transmission being associated with a data service, and an indication that the parameter values associated with the allocated resources are to be used for power control of the UL transmission, wherein the indications are provided in terms of a PUCCH resource indicator field which points to a PUCCH-resource entry in a PUCCH-resource set configured by Radio Resource Control, RRC, the PUCCH-resource entry indicating the parameter values to be used for power control of the UL transmission. configuring the UE with a plurality of resources that can be allocated for UL transmissions based on one or more transmit power control, TPC, parameters, wherein the plurality of resources include: first resources associated with first parameter values for the respective TPC parameters, and second resources associated with second parameter values for the respective TPC parameters, wherein the first parameter values provide increased UL transmission reliability relative to the second parameter values; first resources associated with first parameter values for the respective TPC parameters, and second resources associated with second parameter values for the respective TPC parameters, wherein the first parameter values provide increased UL transmission reliability relative to the second parameter values; transmitting, to a UE, a downlink, DL, control message comprising: an indication that the first resources or the second resources are allocated for an UL transmission of a hybrid-ARQ acknowledgement, HARQ-ACK, on a physical uplink control channel, PUCCH, the UL transmission being associated with a data service, and an indication that the parameter values associated with the allocated resources are to be used for power control of the UL transmission, wherein the indications are provided in terms of a PUCCH resource indicator field which points to a PUCCH-resource entry in a PUCCH-resource set configured by Radio Resource Control, RRC, the PUCCH-resource entry indicating the parameter values to be used for power control of the UL transmission. an indication that the first resources or the second resources are allocated for an UL transmission of a hybrid-ARQ acknowledgement, HARQ-ACK, on a physical uplink control channel, PUCCH, the UL transmission being associated with a data service, and an indication that the parameter values associated with the allocated resources are to be used for power control of the UL transmission, wherein the indications are provided in terms of a PUCCH resource indicator field which points to a PUCCH-resource entry in a PUCCH-resource set configured by Radio Resource Control, RRC, the PUCCH-resource entry indicating the parameter values to be used for power control of the UL transmission.
