Abstract: A method for enhancing receiving signal power at a receiver is provided. The method includes estimating a channel gain by transmitting a pilot signal to the receiver through each antenna from a plurality of antennas of a transmitter and an IRS, determining an antenna selection metric based on the channel gain in transmitting the pilot signal to the receiver through each antenna of the transmitter and the IRS, identifying an antenna from the plurality of antennas that causes to provide the largest antenna selection metric, determining a reflection coefficient for each reflector of the IRS based on the identified antenna, configuring the reflectors of the IRS with the reflection coefficient, and transmitting the signal to the receiver through the identified antenna and the configured reflectors.
