at least one processor; and

at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to perform:

obtaining signal reception information related to at least one downlink signal received by a user equipment using at least one reception antenna panel of a plurality of selectively-activatable antenna panels;

determining an indication of effective power radiatable to a network node from which the at least one downlink signal is received, based on the signal reception information related to the at least one downlink signal received by that antenna panel for each of the plurality of selectively-activatable antenna panels which is configurable to transmit a signal to the network node from which the at least one downlink signal is received;

calculating an indication of power consumption associated with the indication of effective power radiatable to the network node for each of the plurality of selectively-activatable antenna panels; and,

selecting and configuring at least one of the selectively-activatable antenna panels to be used for transmission of the signal to the network node from which the at least one downlink signal is received in response to the calculated indication of power consumption.
