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.
