Abstract: A method includes: separately performing, by a requester, time measurement with a plurality of responders, and calculating a location of the requester based on a measurement result. A measurement result obtained by the requester by performing time measurement with each responder includes time stamps t1, t2, t3, and t4, where t1 is a time when the responder sends a measurement frame, t2 is a time at which the requester receives the measurement frame, t3 is a time when the requester sends an acknowledgement frame in response to the measurement frame, and t4 is a time when the responder receives the acknowledgement frame. The acknowledgement frame is sent by the requester after waiting for a randomly generated short interframe spacing after receiving a last symbol of the measurement frame. The randomly generated short interframe spacing is randomly generated within a specified fluctuation range of a nominal short interframe spacing.

Abstract: This application provides a screen sharing method, a sharing device, and a receiving device. The screen sharing method includes: displaying a user interface of an application menu; establishing a connection used for screen sharing to a receiving device; determining shareable image data, where the shareable image data is a part of image data corresponding to the user interface; and sending the shareable image data to the receiving device by using the connection, so that the receiving device displays the user interface of the application menu according to the shareable image data. When this embodiment is used for screen sharing, a sharing device may send shareable image data to only a receiving device, thereby decreasing security problems caused by screen sharing.

Abstract: Embodiments of the present invention disclose a method and an apparatus for acknowledging transmission of downlink data frames by multiple stations in a wireless local area network. The method includes: sending, by an access point, a corresponding downlink data frame to each station of the multiple stations; and receiving, by the access point after the access point sends the corresponding downlink data frame to each station, acknowledgment messages concurrently sent by the multiple stations on channel resources allocated by the access point to the multiple stations. According to the method and the apparatus provided in the embodiments of the present invention, time required by the multiple stations to feed back the acknowledgment messages can be reduced.
