Classification: CPC H | IPC H

Claim 14:
15. A method, comprising:
determining M channel state information CSI beams, wherein interference noise power of a demodulation reference signal (DMRS) pilot signal carried on each of the M CSI beams is greater than a first preset value, interference noise power of a sounding reference signal (SRS) pilot signal carried on each of the M CSI beams is greater than a second preset value, and M is a positive integer;
obtaining a first angle range corresponding to the M CSI beams;
determining at least one null-steering angle based on the first angle range, wherein the at least one null-steering angle belongs to the first angle range;
determining a vertical plane suppression angle corresponding to each null-steering angle of the at least one null-steering angle; and
performing side lobe suppression on the vertical plane suppression angle corresponding to each null-steering angle in a vertical plane gain directivity pattern, to obtain a maximum antenna gain after side lobe suppression.
