Physical uplink control channel (PUCCH) power control towards multiple transmission-and- reception points (TRPs)

A method implemented in a network node configured to communicate with a wireless device, WD, the method comprising:

• configuring the WD with a list of at least two power control parameter sets for power control of a physical uplink control channel, PUCCH, applicable to at least one of at least one PUCCH resource and at least one group of PUCCH resources;
• and
• transmitting a medium access control, MAC, control element, CE, to the WD to activate at least one power control parameter set from the list of power control parameter sets applicable to at least one of (1) one PUCCH resource, (2) each one of multiple PUCCH resources, and (3) multiple groups of PUCCH resources, the MAC CE including:
• a bandwidth part, BWP, field, a serving cell identifier, ID, field in a first octet;
• a field indicating whether one of one set and two sets of PUCCH power control parameters are activated;
• a 7-bit PUCCH resource index field in a second octet;
• and
• a dedicated field for each of the two sets of PUCCH power control parameters in a third octet.

A wireless device, WD, configured to communicate with a network node, the WD comprising:

• a radio interface configured to receive a medium access control, MAC, control element, CE, from the network node to activate at least one power control parameter set from a list of at least two power control parameter sets for power control of a physical uplink control channel, PUCCH, applicable to at least one of at least one PUCCH resource and at least one group of PUCCH resources;
• and
• processing circuitry in communication with the radio interface and configured to set a transmit power level based at least in part on at least one of the at least two power control parameter sets in the list, the MAC CE including:
• a bandwidth part, BWP, field, a serving cell identifier, ID, field in a first octet;
• a field indicating whether one of one set and two sets of PUCCH power control parameters are activated;
• a 7-bit PUCCH resource index field in a second octet;
• and
• a dedicated field for each of the two sets of PUCCH power control parameters in a third octet.
