摘要： Disclosed are a method and apparatus for an access point (AP) to control channel access of a station in a wireless local area network (WLAN) system. An AP according to one embodiment may determine resource allocation information for protecting a resource for a station not referring to traffic indication map (TIM) information. The determined resource allocation information is transmitted to a station referring to the TIM information, and the station referring to the TIM information does not conduct channel access in a time period specified in the resource allocation information.

摘要： Disclosed is a technique related to a method for controlling synchronization by correcting data transmission time or frequency offset, and to a station. According to the technique, a method for controlling the synchronization of a first terminal for data transmission/reception in a coordinated communication system comprises: a step of transmitting a first request frame and a second request frame containing transmission time information for each of a first response frame and a second response frame to a second terminal and to a third terminal, respectively; a step of receiving the first response frame and the second response frame from the second terminal and the third terminal; a step of estimating a first propagation delay time between the first terminal and the second terminal and a second propagation delay time between the first terminal and the third terminal, using the time of receiving the first response frame and the second response frame; and a step of transmitting, to the second terminal, a third request frame containing information on the delay time difference between the first propagation delay time and the second propagation delay time.

摘要： A scanning method performed by a station (STA) in a wireless LAN system is provided. The method comprises: transmitting a probe request frame; and receiving a short probe response frame from an access point (AP) as a response to the probe request frame. The short probe response frame includes service set ID (SSID) information or compressed SSID information of the AP.

摘要： In a cellular system in which OFDM is used, a forward link synchronization channel, a common pilot channel structure, an initial cell searching method of a mobile station, and an adjacent cell searching method for handover are required. A method of transmitting a forward synchronization signal in a wireless communication system according to the present invention includes generating a frame comprised of a plurality of sync blocks; and transmitting the frame through a forward link, wherein the frame comprises primary synchronization channel sequences which provide timing information of the sync blocks and a plurality of secondary synchronization channel sequences which provide timing information of the frame, wherein a cell identifier is specified by a combination of the primary synchronization channel sequence and a hopping code word specified by the plurality of the secondary synchronization channel sequences Therefore, the cell searching time can be efficiently reduced in an OFDM system.
