Zusammenfassung:A method for a first communication node may include calculating a time delay value on the basis of a carrier frequency based on the number of antenna panels, the number of antennas of each antenna panel, and a space layer that can be generated using a plurality of antennas. The method may also include generating a frequency-dependent first phase shift matrix (PSM) according to each subcarrier by using the calculated time delay value. The method may also include multiplying the first PSM by a basic codebook so as to generate a first codebook for compensating for a beam squint of a beam generated through each antenna.
