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 invention provides a power control method, access point (AP) equipment and station (STA) equipment. AP equipment sends preset frames corresponding to current frames of a current transmit opportunity (TXOP) to STA equipment, wherein the each preset frame includes an operation object identity, a medium access control (MAC) address, subsequent STA indication and group multiplexing correlated sleep indication; therefore, when an operation object identity of a preset frame corresponding to a current frame does not include the identity of the STA equipment and the subsequent STA indication shows that there is no newly-added STA subsequently or the operation object identity of the preset frame corresponding to the current frame include the identity of the STA equipment and the MAC address of the preset frame corresponding to the current frame does not include that of the STA equipment and the group multiplexing correlated sleep indication is in an allowing state, the STA equipment can enter a sleep state. According to the power control method, the AP equipment and the STA equipment, correctness of power conservation can be improved.

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...
