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

The embodiments of the present invention provide an error recovery method, an access point device, a station device, and a system thereof. The error recovery method includes: transmitting a data frame to a station allowed to enter a power save mode, where the data frame is used to indicate the end of user data transmission; and retransmitting the data frame during a current transmission opportunity period if no acknowledgement frame returned by the station in response to the data frame is received. Based on the above technical solution, the access point retransmits the data frame directly during the current transmission opportunity period and there is no need to contend for a new transmission opportunity period to perform the error recovery, thereby speeding up the error recovery and reducing the error recovery delay. Unnecessary contending for a new transmission opportunity period is avoided when the error recovery can be implemented within the current transmission opportunity period, thereby increasing the error recovery efficiency, saving the network resources, and improving the quality of service.

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 (Power Save, PS) power saving mechanism is introduced. In the TXOP PS power saving mechanism, the station (Station, STA) that supports this mechanism is allowed to be It enters the sleep state when certain conditions are met within the TXOP time, so as to achieve the purpose of power saving. [0003] The access point (Access point, AP) can indicate whether it is allowed to be in TXOP PS mode by setting the TXOP_PS_NOT_ALLOWED (TXOP PS not allowed) field in VHT-SIG-A1 (Very High Throughout Signal-A1, very high throughput information A1) STA enters the sleep state, when this field is 0, it means that the STA in T...
