Claim 0:
1. A method, comprising:
in response to determining M channel state information (CSI) beams for which 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 and 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, performing the following:
obtaining a first angle range corresponding to the M CSI beams, wherein M is a positive integer;
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 directivity pattern gain and a suppression multiple that correspond to each null-steering angle in the at least one null-steering angle, wherein each suppression multiple is a ratio of a suppression amount to the corresponding directivity pattern gain; and
determining, for each null-steering angle based on the directivity pattern gain and the suppression multiple that correspond to the each null-steering angle, a cancellation directivity pattern gain corresponding to the each null-steering angle, wherein for the each null steering angle a sum of the cancellation directivity pattern gain and a product of the directivity pattern gain and the suppression multiple corresponding to the each null steering angle is zero.
