Ue and first network node for handling power adjustments

A network node comprising:

• processing circuitry;
• and
• memory coupled with the processing circuitry, the memory including instructions that when executed by the processing circuitry causes the network node to perform operations comprising:
• determining a power backoff indicator, PBI, for a first user equipment, UE, based on at least one of channel conditions of the first UE and channel conditions of a second UE, data reliability requirements of the second UE, and data performance of the first UE;
• estimating an amount of interference reduction needed for second data to be received from the UE fulfilling a requirement, the PBI being determined based on the estimated amount of interference reduction;
• transmitting the PBI to the first UE;
• and
• receiving second data from the first UE, transmission of the second data has having been adjusted based on the PBI.

A method performed by a UE, the method comprising:

• receiving a Power Backoff Indicator, PBI, comprised in a PBI message from a first network node;
• responsive to determining to apply the PBI, backing off the power by adjusting the power according to at least one of a configuration and the PBI;
• transmitting second data to the first network node with the backed off adjusted power;
• and
• disregarding the PBI when at least one of:
• the UE has an allocation which fully overlaps with a power backoff region, PBR;
• and
• the UE receives both a physical downlink control channel, PDCCH, with an uplink grant and a PDCCH with a PBI, and for which PDCCH control resource sets, CORESETS, have a same starting symbol.

A user equipment, UE, comprising:

• processing circuitry;
• and
• memory coupled with the processing circuitry, the memory including instructions that when executed by the processing circuitry causes the UE to perform operations comprising:
• receiving a Power Backoff Indicator, PBI, comprised in a PBI message from the first network node;
• responsive to determining to apply the PBI, backing off the power by adjusting the power according to at least one of configuration and the PBI;
• and
• transmitting second data to the first network node with the backed off adjusted power;
• and
• disregarding the PBI when at least one of:
• the UE has an allocation which fully overlaps with a PBR;
• and
• the UE receives both a physical downlink control channel, PDCCH, with an uplink grant and a PDCCH with a PBI, and for which PDCCH control resource sets, CORESETS, have a same starting symbol.
