Various example embodiments provide a system for mitigating effects of a power back-off due to exposure of user's body to transmitted power. A user equipment (UE) may determine triggering of a power exposure event, for example a body of a user coming close enough to trigger a maximum permissible exposure (MPE) limit. The UE may then send an emergency signal including an indication of the triggered power exposure event to a base station. Various beneficial options for rapidly providing the emergency signal are disclosed. The UE and the base station may enter an emergency mode, where the UE may provide further information on its power back-off conditions. Based on the information received from the UE, the base station may determine to perform adaptation of the radio link to avoid radio link failure. Apparatuses, methods, and computer programs are disclosed.
