Claim of US Patent No. 9,860,857

1. A transmit power control method comprising:
acquiring first information that is used to adjust transmit power for sending a first signal;
acquiring power of each of a plurality of working channels;
determining, from among the plurality of working channels, a to-be-adjusted working channel according to an adjustment step,
the first information, and the power of each of the plurality of working channels;

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.
