US 2017/0251432 A1 · POWER SAVE MODE-BASED OPERATING METHOD AND APPARATUS IN WIRELESS LAN

Abstract

Disclosed are a power save mode-based operating method and apparatus in a wireless LAN. The power save mode-based operating method in a wireless LAN comprises the steps of: receiving, by an STA, overheard BSS information from an AP; receiving, by the STA, a PPDU, wherein the PPDU includes information on a BSS having transmitted the PPDU; determining, by the STA, whether the overheard BSS information includes the information on the BSS; and switching an awake state to a doze state when the STA determines whether the overheard BSS information includes the information on the BSS, wherein the overheard BSS information can include the information on at least one overheard BSS for transmitting a frame enabled to be overheard by the AP.

Claims10

Dependent claims

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

receiving, by a station (STA), overhear basic service set (BSS) information from an access point (AP);
receiving, by the STA, a physical layer protocol data unit (PPDU), wherein the PPDU comprises information on a BSS having transmitted the PPDU;
determining, by the STA, whether the overhear BSS information comprises the information on the BSS;
and
transitioning the STA from an awake state to a doze state if the overhear BSS information comprises the information on the BSS,
wherein the overhear BSS information comprises information on at least one overhear BSS for transmitting a frame which can be overheard by the AP.

3 more elements

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

a radio frequency (RF) unit for transmitting or receiving a radio signal;
and
a processor operatively coupled to the RF unit,
wherein the processor is configured for:
receiving overhear basic service set (BSS) information from an access point (AP);
receiving a physical layer protocol data unit (PPDU);
determining whether the overhear BSS information comprises information on the BSS;
and
transitioning from an awake state to a doze state if the overhear BSS information comprises the information on the BSS,
wherein the PPDU comprises information on a BSS having transmitted the PPDU, and
wherein the overhear BSS information comprises information on at least one overhear BSS for transmitting a frame which can be overheard by the AP.
