Uplink Power Control for Multiple Services

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 the 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.

A method, performed by a user equipment (UE) for power control of uplink (UL) transmissions to a network node of radio access network (RAN), the UL transmissions being associated with a plurality of data services having different reliability requirements, the method comprising:

• receiving, from the network node, a configuration of 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;
• receiving, from the network node, 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.

A network node of a radio access network, the network node being configured for power control of user equipment (UE) uplink (UL) transmissions that are associated with a plurality of data services having different reliability requirements, the network node comprising:

• and
• processing circuitry operatively coupled with the radio network interface, whereby the processing circuitry and the radio network interface are configured to:
• configure a 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;
• transmit, to the 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.
