Abstract: A method for operating a station in a wireless LAN is disclosed. An OFDMA-based communication method comprises the steps of: receiving, from an access point, a first frame including time resource information and frequency resource information indicating a resource occupied for an OFDMA-based communication; and receiving, from the access point, a data frame through the resource indicated by the time resource information and frequency resource information. Therefore, performance of the wireless LAN system can be improved.

Abstract: The present disclosure relates to a method and apparatus for estimating maximum allowable power in a frequency sharing system. A method for performing an available spectrum inquiry according to an embodiment of the present disclosure may comprise: determining an allowable power level for the second device based on whether there is an overlap between an exclusion area for the second device or at least one of the one or more protection area contours and a location uncertainty area of a first device; and transmitting a message for an available spectrum inquiry response including information on the determined allowable power level. Herein, the second device supporting another service whose frequency is shared with a specific service based on location-related information of the first device may be selected.

Abstract: Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.

Abstract: A method and a device for searching for an access point in a wireless LAN are disclosed. An operating method of a station comprising a PCR and a WUR comprises the steps of: allowing the WUR operating in a wake up state to receive a WUR beacon frame from an access point; shifting an operating state of the PCR from a sleep state to the wake up state, when the WUR beacon frame is received; and allowing the PCR operating in the wake up state to communicate with the access point. Therefore, the performance of a communication system can be improved.
