A power save mode-based operating method and device in a WLAN are disclosed. The power save mode-based operating method in the WLAN may include: transmitting, by an STA, a first trigger frame to an AP; receiving, by the STA, a downlink frame transmitted by the AP based on the first trigger frame on a first service section; receiving, by the STA, traffic indication information from the AP on a second service section after the reception of the downlink frame; determining, by the STA, the presence or absence of a pending downlink frame at the AP based on the traffic indication information on the second service section; and determining, by the STA, a power saving mode based on the presence or absence of the pending downlink frame. |
