    摘要： A method for a power save mode operation in a wireless local area network (WLAN) system is provided. The method includes transmitting, by an access point (AP), a traffic indication map (TIM) element that announces existence of buffered traffic, wherein the TIM element includes an association ID (AID) assigned to a buffered STA having the buffered traffic when the buffered station (STA) is associated with the AP; receiving, by the AP, a poll frame for requesting data frame transmission from a candidate STA, wherein the poll frame contains an AID of the candidate STA and a medium access control (MAC) address which is a unique identifying information of the candidate STA; and determining, by the AP, whether the candidate STA is the buffered STA on the basis of the AID and the MAC address of the candidate STA.

    摘要： A method for a power save mode operation in a wireless local area network (WLAN) system is provided. The method comprising determining a type of a receiving station (STA) indicator on the basis of the number of STAs which are associated with the AP and which intend to transmit buffered traffic; generating a traffic indicator map (TIM) element including information which indicates the receiving STA indicator and the type of the receiving STA indicator, transmitting the TIM element, receiving a poll frame for requesting data frame transmission from one STA among the STAs and transmitting the data frame to the STA.

    摘要： Provided is a method for operating a power save mode performed by an access point in a WLAN system. The method includes: transmitting, by an access point (AP), a first traffic indication map (TIM) broadcast indication frame to a first station (STA); transmitting, by the AP, a second TIM broadcast indication frame to a second STA; transmitting, by the AP, a first TIM frame indicating that buffered traffic to the first STA is present; and transmitting, by the AP, a second TIM frame indicating that buffered traffic to the second STA is present. The first TIM broadcast indication frame includes a first TIM offset field indicating a transmission time of the first TIM frame, and the second TIM broadcast indication frame includes a second TIM offset field indicating a transmission time of the second TIM frame.
