APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM OF CENTRALIZED MAC

摘要

PURPOSE: An apparatus and a method for transmitting and receiving data in a wireless communication system based on a centralized MAC(Medium Access Control) are provided to smoothly communicate data through a relay route by a piconet coordinator even though a direct route of LOS(Line of Sight) is blocked between devices and a state of a channel is not good. CONSTITUTION: A route setting unit(201) sets up a communication route of a correspondence device and a piconet coordinator. A route determining unit(203) determines whether the set communication route is available. A route selecting unit(207) selects one among the communication routes according to whether the set communication route is available. A data transceiving unit(209) exchanges data through the selected route.
