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. |
