The method, performed by a UE, includes being configured more than one panel-specific maximum powers of different panels; and computing power headroom (PH), wherein the PH is a UE-specific PH which is a sum of the panel-specific maximum powers of the panels minus a sum of panel-specific scheduling powers of UL transmissions on the panels, or wherein the PH is a panel-specific PH of one panel which is the panel-specific maximum power of the panel minus the panel-specific scheduling power of the UL transmission on the panel. With this method, power headroom reporting can be achieved for multiple panels performing simultaneous UL transmissions in the UE. In addition, the UE may compute the UE-specific PH or the panel-specific PH for another configuration, e.g., the UE is configured a UE-specific maximum power.
