ABSTRACT:
A wireless communication apparatus and a method for compensating offset using the same are disclosed, in which offset due to latency in a power save mode is efficiently compensated. The wireless communication apparatus includes a frequency matched unit for compensating offset due to latency that may occur during communication between the wireless communication apparatus and an external equipment. The frequency matched unit adds a clock value corresponding to predetermined frames to a clock value of a system clock if any one of a hold mode, a sniff mode, or a park mode is transited to a normal mode. Thus, the offset generated in the frames can efficiently be compensated if the hold mode, the sniff mode or the park mode is transited to the normal mode.
