摘要： Provided is a communication method by a station (STA) that operates in a power safe mode in a wireless LAN system. The method comprises: transmitting a probe request frame to an access point (AP), wherein the probe request frame includes system information identification information for identifying system information acquired by the STA; and receiving a probe response frame as a response to the probe request frame from the AP. The probe response frame includes a time stamp value related to the point of time of transmitting the probe response frame, and if it is determined, based on the system information identification information, that updated information which is not included in said acquired system information exists, the probe response frame further includes said updated information. Also provided is a communication method by an access point (AP) in a wireless LAN system. The method comprises: receiving a probe request frame from a station (STA), wherein the probe request frame includes information related to a wake-up duration time that is a time period in which the STA operates in an awake state; and transmitting a probe response frame to the STA as a response to the probe request frame.

摘要： Disclosed are a method and a device for transmitting and receiving a frame using a short guard interval. A method for receiving a beacon frame comprises the steps of: receiving a first beacon frame which contains guard interval type information; determining a second beacon frame which is to be received after the first beacon frame on the basis of the guard interval type information; and receiving the second beacon frame, wherein the guard interval type information may be information which is related to a guard interval used when said second beacon frame is transmitted. Thus, since a station can determine whether to receive a frame using a certain guard interval, the station can receive a power-saving effect.

摘要： Disclosed are method and device for indicating a PLCP header transmission mode. A method for generating a physical layer convergence protocol (PLCP) of a data frame can comprise the following steps: demodulating PLCP header mode information based on a scrambling sequence of the received frame or information elements included in the received frame; and generating a data frame including the PLCP header generated based on the PCLP header mode information. The PLCP header mode information comprises at least one indication from a space time block coding mode indication, a guard interval mode indication, and a repetition mode indication. The invention is capable of improving data transmission efficiency by adaptively determining a transmission mode of a PCLP header to a channel situation.

摘要： Disclosed are a method and an apparatus for indicating a frame type using a physical layer convergence protocol header. A method for determining a frame type using a PLCP header may comprise: a step of demodulating a frame type contained in an SIG of the PLCP header so as to acquire information indicating a physical service data unit (PSDU) of a frame; and a step of acquiring frame information required for demodulating the frame contained in the SIG dependently on the information indicating PSDU. Thus, unnecessary information may not be additionally demodulated to thereby improve demodulation efficiency and reduce unnecessary power consumption.
