Embodiments of the present invention provide a power save method and a station device. The method includes: receiving, by a station, STA, a null data packet announcement, NDPA, frame, and obtaining a STA association identifier, AID, in a STA information field in the NDPA frame; 5 comparing, by the STA, its STA AID with the obtained STA AID, and determining whether its STA AID is the same as the obtained STA AID; and when the STA determines that its STA AID is different from the obtained STA AID, allowing the STA to enter a doze state. Embodiments of the present invention can reduce the power consumption during the TXOP period and save resources. A STA confiuns, according to a frame type identifier in a received frame , that the received frame is an NDPA frame, and 101 obtains a STA AID in a STA information field in the NDPA frame Yes The STA determines whether its No TA AID fte same as the obtained STA AID--- Return CS! information to the AP A low to enter the Doze state AID Feedback type Ne index FIG. lC |
