1. A method performed by a wireless device (UE), for reporting a power headroom (PH) to a network node, the UE connecting to a cell by means of a supplementary uplink (SUL) carrier and a New Radio uplink carrier (NRUC); the method comprising the UE:
receiving a configuration to apply a first Power Headroom Report (PHR) format for a PHR reporting power headroom for multiple uplink channels in the cell;
generating a PHR, the PHR comprising a PH information for each of the SUL carrier and the NRUC;
transmitting the PHR to the network node; and
the SUL carrier is configured to extend an uplink, UL, coverage of the NR uplink carrier, the PHR is indicative of a first PH value and first maximum transmission power associated to the SUL carrier, a second PH value based on a real transmission or a reference format and a second maximum transmission power associated to the NRUC, and a range of the first PH value is different from a range of the second PH value, and the PH information for each the SUL carrier and the NRUC is indicated by corresponding carrier-specific indices in the PHR.
