Abstract: The present invention relates to a device and method for allocating a coexistence resource in an unlicensed band. The device according to the present invention comprises: a frame configuration unit for configuring a subframe in which data and a reference signal for a channel in an unlicensed band are allocated, and allocating a part of the symbols of the subframe as a coexistence resource; a signal detection unit for detecting a signal of another LTE system or Wi-Fi system during a transmission idle period where the coexistence resource is allocated; and a transmission processing unit which, when the signal of another system is detected during the transmission idle period, does not occupy a resource for the next subframe, and when the occupation of the coexistence resource by the another system has ended, occupies the resource for the next subframe.

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.
