Abstract: An example wake-up packet sending method includes obtaining, by a sending apparatus, a wake-up packet (WUP), where the WUP includes a preamble sequence, and sending the WUP to wake up a main receiver of a receiving apparatus. The preamble sequence includes N consecutive first sequences S, where N is an integer greater than or equal to 2 (for example, [S S]), and the N consecutive first sequences S are used to indicate that a data rate used for the WUP is a first value. Or the preamble sequence includes a second sequence M, where the second sequence M is used to indicate that a data rate used for the WUP is a second value, and the second sequence M and a first sequence S are in a bit logical negation relationship.

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.
