Claim 8:
9. A method, performed by a base station, for utilizing power headroom (PH) information received from a wireless device (UE) configured with a supplementary uplink (SUL) carrier and a New Radio uplink carrier (NRUC) within a cell, the method comprising the base station:
configuring the UE with a first power headroom report (PHR) format to support power headroom reporting for multiple uplink channels in the cell;
implementing power headroom, PH, information from the received PHR for managing wireless communication in the cell;
receiving at least one power headroom report, PHR, for the SUL carrier and the NR uplink carrier, the PHR using the first PHR format; and

the SUL carrier is configured to extend an uplink, UL, coverage of the NR uplink carrier, and the PHR is indicative of a first PH value and a first maximum transmission power associated to the SUL carrier, and 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.
