Power saving method, access point equipment and station equipment

Abstract

The invention provides a power saving method, access point (AP) equipment and station (STA) equipment. The AP equipment respectively sets transmit opportunity (TXOP) power saving instruction of each frame according to whether the power saving is allowed to be performed at the current TXOP and the existence of a newly added STA in an operation object identification of the subsequent frame of each frame of the current TXOP; when the TXOP power saving instruction of the current frame is that the power saving is allowed, the STA equipment determines whether to enter a sleep state or not according to a judgment result of the sleep condition; or when the current frame comprises the subsequent STA instruction and the TXOP power saving instruction, and when the TXOP power saving instruction of the current frame is that the power saving is allowed and the operation object identification of the preset frame does not contain the instruction of the STA equipment and the subsequent STA instruction of the current frame is that the subsequent operation object identification does not have the newly added STA, the STA equipment enters the sleep state. By adopting the method and the equipment provided by the invention, the application range of the power saving can be enlarged, and a power saving effect can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a power saving method, an access point (Access Point, AP for short) device, and a station station (Station, STA for short) device. Background technique [0002] For a multiple-input multiple-output (MIMO for short) wireless communication system, in a transmission opportunity (Transmit Opportunity, TXOP for short), not all in a Basic Service Set (BSS for short) All STA devices need to receive data. Therefore, a power saving method is adopted in a wireless communication system to allow STA devices that do not receive data in a current TXOP to enter a sleep state. The STA device in the sleep state turns off its own receiver, thereby reducing power consumption. [0003] At present, the power saving method of the wireless communication system is as follows: the AP device sends an operation object identifier and a prohibition of TXOP power saving instr...

Problems solved by technology

Therefore, for the multi-user MIMO (Multi-User MIMO, MU-MIMO for short) mode, using the existing power saving method, it is only applicable to the operation object identifier in the first frame of the TXOP including all the devices involved in the TXOP that have entered sleep In the case of STA devices with state functions, and for Single-User MIMO (Single-User MIMO, SU-MIMO for short) mode, this method is only applicable to the operation object identifier of each frame of TXOP and only indicates that no more than one has entered the sleep state In the case of STA devices with multiple functions, power saving can only be performed in a few scenarios, and the application range is small, so the effect of power saving is not good
