Embodiment Construction

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work 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 a station that is allowed to enter the power saving mode, the data frame is used to indicate that the user data is sent; in S120, if the station does not receive an acknowledgement frame returned in response to the data frame , To resend th...

Abstract

The embodiment of the invention provides an error recovery method, access point equipment, station equipment and an error recovery system. The error recovery method comprises the following steps: data frames are sent to stations which are allowed to enter a power saving mode, and the data frames are used for indicating that user data is sent; and if acknowledgment frames returned by stations responding to the data frames are not received, and data is sent to stations again within the current transmit opportunity time. Based on the technical scheme, data is directly transmitted again through access points within the current transmit opportunity time without competing new transmission opportunity time to recover errors, so that the time of recovering errors is accelerated, the delaying time of recovering errors is reduced, and the unnecessary competition of the transmit opportunity time is avoided under the condition that errors can be recovered within the current transmit opportunity time, so that the efficiency of recovering errors is improved, the network resource is saved, and the service quality is improved.

Description

Technical field [0001] The present invention relates to the field of wireless local area networks, and more specifically, to an error recovery method, access point equipment, site equipment and systems thereof in the field of wireless local area networks. Background technique [0002] In the new standard, a transmission opportunity (TXOP) power saving (Power Save, PS) power saving mechanism is introduced. In the TXOP PS power saving mechanism, a station (Station, STA) that supports this mechanism is allowed to act Enter the sleep state when certain conditions are met within the TXOP time, so as to achieve the purpose of power saving. [0003] Access point (AP) can indicate whether to allow TXOP PS mode by setting TXOP_PS_NOT_ALLOWED (TXOP PS not allowed) field in VHT-SIG-A1 (Very High Throughout Signal-A1, Very High Throughout Signal-A1) When this field is 0, it means that the STA in TXOP PS mode is allowed to enter the sleep state, otherwise it is not allowed to enter the sleep s...
