FIELD: radio engineering, communication.
SUBSTANCE: invention discloses a power saving method, an access point (AP) and a station (STA). According to whether power saving is allowed in a current transmit opportunity (TXOP) and whether a STA is newly added in an operation object identifier of a subsequent frame of each frame of the current TXOP, the AP respectively sets a TXOP power saving indication of each frame. When the TXOP power saving indication of the current frame is power saving allowed, the STA determines whether to enter the doze state according to a judgment result for a doze condition. Alternatively, the current frame includes a subsequent STA indication and a TXOP power saving indication, and when the TXOP power saving indication of the current frame is allowed, the operation object identifier of the preset frame does not include an indication for this STA, and the subsequent STA indication of the current frame is that no identifier of a STA is newly added subsequently, the STA device enters a doze state.
EFFECT: wider range of using a power saving mode and higher power saving effect.
