    adjusting the to-be-adjusted working channel to thereby adjust so as to adjust the transmit power for sending the first signal;

    acquiring phase shifts of the plurality of working channels before the adjusting, and phase shifts of the plurality of working channels after the adjusting;

    determining whether the phase shifts of the plurality of working channels after the adjusting are different from the phase shifts of the plurality of working channels before the adjusting; and

    upon determining that the phase shifts of the plurality of working channels after the adjusting are different from the phase shifts of the plurality of working channels before the adjusting, adjusting the phase shifts of the plurality of working channels after the adjusting, so that the phase shifts of the plurality of working channels after the adjusting are the same as the phase shifts of the plurality of working channels before the adjusting.
