Classification: CPC H | IPC H

Claim 16:
17. A base station configured to utilize 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 base station comprising:
processing circuitry; and
memory containing instructions executable by the processing circuitry the base station being configured to:
configure the UE with a first power headroom report (PHR) format to support power headroom reporting for multiple uplink channels in the cell;

implement power headroom, PH, information from the received PHR for managing wireless communication in the cell;
receive 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.
