Problems solved by technology

This will lead to a reduction in transmission efficiency, and because it needs to compete for a new TXOP time to perform error recovery, the delay in error recovery will increase and the quality of service will decrease

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions of the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] First, combine figure 1 An error recovery method 100 according to an embodiment of the present invention is described.

[0027] Such as figure 1 As shown, the method 100 includes: in S110, sending a data frame to the station that is allowed to enter the power saving mode, and the data frame is used to indicate that the user data has been sent; in S120, if the confirmation frame returned by the station in response to the data frame is not received , rese...

Abstract

An embodiment of the invention provides an error recovery method, access point equipment, site equipment and a site system. The error recovery method includes: sending a data frame to a site allowed to access to a power-saving mode, wherein the data frame is used for indicating that sending of user data is finished; if an acknowledgement frame responding to the data frame by the site is not received, re-sending the data to the site within current transmission opportunity time. On the basis of the technical scheme, an access point directly performs re-transmission within current transmission opportunity time instead of competing for new transmission opportunity time for error recovery, so that error recovery can be accelerated, time delay in error recovery is reduced, and unnecessary competition for transmission opportunity time under the condition that error recovery can be realized in the current transmission opportunity time can be avoided. Therefore, error recovery efficiency can be improved, network resources are saved, and service quality is improved.

Description

technical field [0001] The present invention relates to the field of wireless local area network, and more specifically, to an error recovery method, access point device, station device and system thereof in the field of wireless local area network. Background technique [0002] In the new standard, a transmission opportunity (Transmit opportunity, TXOP) power saving (PowerSave, PS) power saving mechanism is introduced. In the TXOP PS power saving mechanism, a station (Station, STA) that supports this mechanism is allowed to When certain conditions are met within the TXOP time, it enters the sleep state, so as to achieve the purpose of saving power. [0003] The access point (Access point, AP) can indicate whether to allow the TXOP PS mode by setting the TXOP_PS_NOT_ALLOWED (TXOP PS not allowed) field in the VHT-SIG-A1 (Very High ThroughoutSignal-A1, very high throughput information A1) The STA enters the sleep state. When this field is 0, it means that the STA in TXOP PS m...
