First Claim
Patent Images
1. A wireless communication system comprising:
- external equipment; and
an apparatus comprising;
a transceiver for transmitting and receiving data packets to and from the external equipment; and
a frequency matched unit for compensating an offset due to latency that may occur during communication between the apparatus and the external equipment by adding a clock value corresponding to predetermined frames to a clock value of a system clock if power save mode is transited to normal mode.

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.

15. A method of operating a wireless communication system, comprising:
-
selecting an apparatus to serve as a master apparatus, wherein any additionally connected apparatus is a slave apparatus, and all connected apparatuses make up a piconet; calculating a frequency hopping row and a channel access code of a channel within the piconet based on a system clock of the master apparatus;
wherein each said slave apparatus adds an offset value to each slave clock to synchronize the slave clock with the system clock of the master apparatus;transmitting and receiving data packets to and from the apparatuses in the piconet; and compensating an offset due to latency that may occur during communication between the apparatuses in the piconet by adding a clock value corresponding to predetermined frames to a clock value of a system clock if power save mode is transited to normal mode.
