US 2017/0013555 A1 · POWER SAVE MODE-BASED OPERATION METHOD AND DEVICE IN WIRELESS LAN

Abstract

A power save mode-based operation method and device in a wireless LAN are disclosed. The power save mode-based operation method and device in a wireless LAN can comprise the steps of: transmitting, by an STA, a first trigger frame to an AP in a first service interval; receiving, by the STA, a downlink frame transmitted by the AP on the basis of the first trigger frame in the first service interval; receiving, by the STA, traffic indication information from the AP in a second service interval after reception of the downlink frame; determining, by the STA, whether a pending downlink frame of the AP exists on the basis of the traffic indication information in the second service interval; and determining, by the STA, a mode for saving power on the basis of whether the pending downlink frame exists.

Dependent claims

An operation method based on a power saving mode in a wireless local area network (WLAN), the method comprising:

transmitting, by a station (STA), a first trigger frame to an access point (AP) in a first service interval;
receiving, by the STA, a downlink frame transmitted by the AP based on the first trigger frame in the first service interval;
receiving, by the STA, traffic indication information from the AP in a second service interval after receiving the downlink frame;
determining, by the STA, whether there is a pending downlink frame in the AP based on the traffic indication information in the second service interval;
and
determining, by the STA, a mode for power saving based on whether there is the pending downlink frame,
wherein the traffic indication information comprises information on presence of the pending downlink frame to be transmitted by the AP in the second service interval.

4 more elements

A station (STA) operating based on a power saving mode in a wireless local area network (WLAN), the STA comprising:

a radio frequency (RF) unit configured to transmit or receive a radio signal;
and
a processor operatively connected to the RF unit,
wherein the processor is configured to transmit a first trigger frame to an access point (AP) in a first service interval,
to receive a downlink frame transmitted by the AP based on the first trigger frame in the first service interval,
to receive traffic indication information from the AP in a second service interval after receiving the downlink frame,
to determine whether there is a pending downlink frame in the AP based on the traffic indication information in the second service interval, and
to determine a mode for power saving based on whether there is the pending downlink frame, and
the traffic indication information comprises information on presence of the pending downlink frame to be transmitted by the AP in the second service interval.
