Abstract: This application provides a data transmission method. When performing data transmission with a first station in a bandwidth power saving mode by using an operating channel of the first station, an access point performs data transmission with a second station by using an operating channel of the second station. Therefore, even if the operating channel of the first station includes a primary channel, the access point can still perform data transmission with the second station by using another channel. Further, for the access point, although the operating channel of the first station occupies only a part of available bandwidth resources of the access point, the access point can still perform data transmission with the second station by using a remaining channel.

Abstract: The embodiments of the present disclosure 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 indicates the end of 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, thereby increasing the error recovery efficiency, saving the network resources, and improving the quality of service.
