1. An apparatus comprising
at least two antenna arrays;
at least one processor; and
at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
measuring, per an antenna array, downlink reference signals received from transmission-reception points;
checking, per a transmission-reception point, based on measurement results, whether a downlink reference signal from the transmission-reception point is received in a serving antenna array and in one or more non-serving antenna arrays with a delay;
determining, per a non-serving antenna array included in the one or more non-serving antenna arrays that received the downlink reference signal with the delay, the non-serving antenna array to be an alternative antenna array to the serving antenna array;
selecting, when the serving antenna array is under a maximum permissible exposure event, based on at least power levels of antenna arrays, which one of one or more non-serving antenna arrays and the serving antenna array is to be used for transmitting at least a positioning signal to the transmission-reception point; and
transmitting at least the positioning signal to the transmission-reception point using the selected antenna array.
