Embodiment Construction

[0070] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0071] In the existing power control method, each frame sent by the AP device to the SAT device includes an indication of prohibiting TXOP power saving, an operation object identifier and a Medium Access Control Address (MAC address for short). In the MU-MIMO mode, the frame sent by the AP includes a packet header sent through VHT-SIG-A signaling,...

Abstract

The present invention provides a power control method, an access point (AP) device and a terminal station (STA) device. The AP device sends to the STA device a preset frame corresponding to a current frame of a current TXOP, each frame comprising: an operation object identifier, an MAC address, a subsequent STA indication and a group multiplexing related sleep indication, so that when the operation object identifier of the preset frame corresponding to the current frame does not comprise the STA device and the subsequent STA indication indicates that no new STA is added subsequently, or when the operation object identifier of the preset frame corresponding to the current frame comprises the STA device, the MAC address of the preset frame corresponding to the current frame does not comprise the STA device, and the group multiplexing related sleep indication indicates permission, the STA device may enter a sleep state. The power control method, AP device and STA device provided in the present invention can improve the correctness of power saving.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a power control method, an access point (Access Point, AP for short) device, and a station station (Station, STA for short) device. Background technique [0002] For a multi-input multi-output (MultiDle-Input Multi-Output, MIMO for short) wireless communication system, in a transmission opportunity (Transmit Opportunity, TXOP for short), not all of the basic service set (Basic Service Set, BSS for short) All STA devices need to receive data. Therefore, a power control 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 control method of the wireless communication system is as follows: the AP device sends an operation object identifi...
