That is, the terminal includes a plurality of antenna arrays, and any one of the antenna arrays may be selected as a transmitting antenna array, or any one of the antenna arrays may be selected as a receiving antenna array. When one of the antennas is used as a transmitting antenna array and one is used as a receiving antenna array, and after all the combinations of the parameters are adjusted, the interference can be detected, the transmitting antenna array is adjusted to another antenna array and/or the receiving antenna array is adjusted to another antenna array, so that the terminal has no interference.
In the embodiment of the present application, if none of the above adjustment manners can eliminate interference and the terminal has at least three millimeter wave antenna arrays, the antenna arrays of the transmit beam and/or the receive beam may be adjusted to eliminate interference. The terminal can still keep the same-frequency full duplex state after the interference occurs, so that the time domain resource is fully utilized, the communication rate is improved, and the user experience is improved.
