1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory including computer program code that, when executed by the at least one processor, cause the at least one processor to perform the following operations:
determine a triggering of a power exposure event at a user equipment;
enable a timer in response to the triggering of the power exposure event;
send a first indication of the triggered power exposure event to a network device, wherein the first indication of the triggered power exposure event is sent before expiry of the timer;
determine an expected power reduction for complying with a power exposure requirement, wherein the expected power reduction is determined based on a duty cycle of the user equipment;
send second indication of the expected power reduction to the network device;
apply a duty cycle reduction in response to expiry of the timer;
determine that the power exposure event continues to be triggered after applying the duty cycle reduction;
send, to the network device, a third indication of a second expected power reduction and an expected duty cycle reduction; and
in response to receiving the third indication, perform adaptation of a radio link between the network device and the user equipment, wherein the adaptation of the radio link comprises:
determining to redirect at least one beam;
determining to switch a panel;
determining to apply multiple transmission and reception points;
determining to perform a handover; and
determining to switch a radio access technology.
