1. A method comprising:
receiving, by an apparatus from a base station, configuration information comprising a set of candidate beams of the apparatus;
selecting, by the apparatus, one or multiple apparatus transmit and apparatus receive beam pairs, wherein the apparatus transmit beam and apparatus receive beam of the one or multiple apparatus transmit and apparatus receive beam pairs belongs to the set of candidate beams;
for each apparatus transmit and apparatus receive beam pair:
transmitting, by the apparatus, a reference signal (RS) on the apparatus transmit beam;
measuring, by the apparatus, interference signal strength of the RS on the apparatus receive beam;
determining, by the apparatus, self-interference status for the apparatus transmit beam and the apparatus receive beam based on the measured interference signal strength;
selecting, an apparatus transmit and apparatus receive beam pair based on the determined self-interference status, wherein the selected apparatus transmit and apparatus receive beam pair belongs to the one or multiple apparatus transmit and apparatus receive beam pairs; and
transmitting, by the apparatus to the base station, an identification of an apparatus transmit beam and an apparatus receive beam of the selected apparatus transmit and apparatus receive beam pair.
