摘要： The present invention relates to a wireless local area network (WLAN). In the present invention, an access point transmits and receives a probe frame including identity numbers of each access point with a near access point, determines a master access point, and establishes a connection with a near access point through a first radio channel. The master access point transmits a beacon frame, including time information, to a station through a second radio channel, and establishes a connection with the station. The master access point relays a wired internet service received from internet network to the station. Thereafter the master access point switches the connection to the first radio channel and transmits a data frame to the near access point connected with a target station.

摘要： The present invention relates to a transmitting apparatus of a wireless communication system, and a method thereof. The transmitting apparatus monitors receiving of response data for data that has been transmitted to a receiving end, and sets a first parameter for counting successful receipts according to receiving on the response data. The transmitting apparatus demodulates the response data and extracts the number of demodulated data that satisfies a first set value. Subsequently, it is determined whether the first parameter satisfies a second set value and the number of demodulated data satisfies a predetermined ratio of a referential amount of packets. According to the present invention, an efficient transmission mode for a channel state can be provided with reference to an extracted number of soft-decision data from response data received at a receiving end. In addition, a transmission mode can be determined by using only response data according to the present invention.
