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.
Claims15
An operation method of a station including a transceiver and a receiver in a wireless local area network (WLAN) based communication system, the operation method comprising:
- transmitting, by the transceiver, information indicating a transition time to an access point;
- receiving, by the transceiver, one or more parameters for a wake-up radio (WUR) mode from the access point;
- when the one or more parameters are received, operating in the WUR mode;
- receiving, by the receiver included in the station operating in the WUR mode, a wake-up frame from the access point;
- and
- when the wake-up frame is received, transitioning an operation state of the transceiver from a doze state to an awake state,
- wherein the transition time is a time required for the transceiver to transit from the doze state to the awake state, the one or more parameters include a frequency division multiple access (FDMA) parameter indicating a channel in which the wake-up frame is transmitted, and the wake-up frame is received in the channel indicated by the FDMA parameter.
An operation method of an access point in a wireless local area network (WLAN) based communication system, the operation method comprising:
- receiving, from a station, information indicating a transition time;
- transmitting, to the station, one or more parameters for a wake-up radio (WUR) mode;
- and
- transmitting, to the station operating in the WUR mode, a wake-up frame,
- wherein the station includes a transceiver and a receiver, and the transition time is a time required for the transceiver to transit from a doze state to an awake state, the one or more parameters include a frequency division multiple access (FDMA) parameter indicating a channel in which the wake-up frame is transmitted, and the wake-up frame is transmitted in the channel indicated by the FDMA parameter.
A station in a wireless local area network (WLAN) based communication system, the station comprising a processor, a transceiver which operates according to control of the processor, a receiver which operates according to control of the processor, and a memory storing one or more commands executed by the processor,
- wherein the one or more commands are executed to:
- transmit, by the transceiver, information indicating a transition time to an access point;
- receive, by the transceiver, one or more parameters for a wake-up radio (WUR) mode from the access point;
- when the one or more parameters are received, operate in the WUR mode;
- receive, by the receiver included in the station operating in the WUR mode, a wake-up frame from the access point;
- and
- when the wake-up frame is received, transition an operation state of the transceiver from a doze state to an awake state,
- wherein the transition time is a time required for the transceiver to transit from the doze state to the awake state, the one or more parameters include a frequency division multiple access (FDMA) parameter indicating a channel in which the wake-up frame is transmitted, and the wake-up frame is received in the channel indicated by the FDMA parameter.
