Method and arrangement in a base station for scheduling physical resources in a transmission bandwidth to a user equipment served by the base station. The physical resources may be physical channels or radio resource blocks. Some physical resources within the transmission bandwidth are subjected to a performance requirement power restriction value. The method comprises scheduling physical resources based on the performance requirement power restriction value of the physical resources to be scheduled. Also, a method and arrangement in a user equipment for assisting a base station in scheduling physical resources in a transmission bandwidth to the user equipment is described.
