ABSTRACT:
A wireless communication system, apparatus and a method for compensating offset using the same are disclosed, in which offset due to latency in a power save mode is 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 external equipment. The frequency matched unit adds a predetermined time to a clock value of a system clock if power save mode is transited to normal mode. Thus, the offset generated can efficiently be compensated if the power save mode is transited to the normal mode.
