摘要： 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.

摘要： 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.
