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.
Claims9
An operation method of an access point in a communication system, the operation method comprising:
- generating, by the access point, a beacon frame including information indicating a wake-up radio (WUR) channel used for transmission of a WUR frame;
- transmitting, by the access point, the beacon frame;
- and
- transmitting, by the access point, the WUR frame in the WUR channel indicated by the beacon frame,
- wherein a station performing communications with the access point operates in a normal mode or in a WUR mode, the station includes a primary connectivity radio (PCR) and a WUR, and the beacon frame further includes information indicating a duty-cycle duration of the WUR and information indicating a time required for transitioning an operation state of the PCR from a sleep state to a wake-up state.
An operation method of a station in a communication system, the operation method comprising:
- receiving, by the station, a beacon frame including information indicating a wake-up radio (WUR) channel used for transmission of a WUR frame from an access point;
- identifying, by the station, the WUR channel indicated by the beacon frame;
- and
- performing, by the station, a monitoring operation for receiving the WUR frame in the WUR channel,
- wherein the station operates in a normal mode or in a WUR mode, the station includes a primary connectivity radio (PCR) and a WUR, and the beacon frame further includes information indicating a duty-cycle duration of the WUR and information indicating a time required for transitioning an operation state of the PCR from a sleep state to a wake-up state.
