FIELD: physics, communications.
SUBSTANCE: invention relates to wireless communication. User equipment (700) is configured to decide on application or not of a power reduction and to indicate said decision in a power headroom report intended for transmission to a radio base station (600). The radio base station (600) is configured to receive the power headroom report and based on the indicated information in the received power headroom report, the base station is made aware of an additional or special power backoff (e.g. to fulfil SAR requirements) that has been applied and is therefore able to distinguish it from normal power backoff or power reduction.
EFFECT: invention is intended to indicate power backoff in at least a power headroom report in a communication system.
