Abstract: Embodiments of the present invention provide a method and an apparatus for power control. In one embodiment, a current serving node is a first base station. A first switching time at which the second base station switches from transmission of a non-ABS subframe to transmission of an ABS subframe is determined according to an ABS pattern parameter of a second base station. At the first switching time, a target SINR value is adjusted before current switching to obtain a target SINR value of the first switching time.
