Wireless communication apparatus and method for compensating offset using the same
First Claim
1. A wireless communication apparatus comprising:
- a transceiver for transmitting and receiving data packets to and from an external equipment; and
a frequency matched unit for compensating an offset due to latency that may occur during communication between the wireless communication apparatus and the external equipment by adding 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.

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.
