Claim:
1. A method for power control, the method comprising: determining that a current serving node is a first base station; determining, according to almost blank subframe (ABS) pattern parameters of a second base station, a first time point at which the second base station switches from transmission of a non-ABS subframe to transmission of an ABS subframe in a downlink channel using an ABS pattern, wherein the second base station has co-channel interference in the first base station; obtaining a first switching time according to a time offset of the downlink channel that uses the ABS pattern and is relative to a Primary Common Control Physical Channel (P-CCPCH), a subframe offset, and the first time point; and at the first switching time, adjusting a target signal to interference plus noise ratio (SINR) value before current switching to obtain a target SINR value of the first switching time, so that the target SINR value of the first switching time is used as an initial target SINR value for performing inner loop power control for the first base station in a transmission time segment of the ABS subframe, wherein the target SINR value of the first switching time is greater than the target SINR value before current switching.
