Power save method, access point device, and station device

摘要

A power save method, an AP device and an STA device are provided. According to whether power save is allowed in a current TXOP and whether a station STA is newly added in an operation object identifier of a subsequent frame of each frame of the current TXOP, the AP device respectively sets a TXOP power save indication of each frame, and when the TXOP power save indication of the current frame is power save allowed, the STA device determines whether to enter the Doze state according to a judgment result for a doze condition. The adoption of the method and the device can expand the power save application range, and enhance the power save effect.

主权项

1. A power save method, comprising:
setting a power save indication of a current data frame, wherein the power save indication indicates that a station (STA) receiving the current data frame is capable of being allowed to enter a power save state; and sending the current data frame in a current transmit opportunity (TXOP), so that the STA receiving the current data frame determines whether to enter a Doze state according to a judgment result for a doze condition; wherein: a power save indication is included in at least one data frame that is sent before the current data frame and is sent in the current TXOP, the STA is an STA device having a function of entering the Doze state, and power save indications in all data frames before the current data frame that are sent in the current TXOP indicate that an STA is forbidden to enter the power save state, and power save indications in all subsequent data frames of the current data frame that are sent in the current TXOP indicate that an STA is capable of being allowed to enter the power save state.
