APPARATUS AND METHOD FOR CONTROLLING TRANSMISSION SCHEDULE FOR BUFFERED DATA IN WIRELESS LAN, AND TERMINAL FOR RECEIVING BUFFERED DATA BASED ON TRANSMISSION SCHEDULE IN WIRELESS LAN

摘要

Disclosed is a technology that enables an access point, configured to manage a network, to control a transmission schedule of buffered data and enables a terminal to obtain information associated with the transmission schedule in a wireless local area network (WLAN) environment. An apparatus for controlling a transmission schedule of buffered data in a WLAN according to an embodiment may group terminals based on at least one of a service characteristic and a traffic characteristic of each of the terminals, assign group information to each of the grouped groups to wake up in a different time, and transmit at least one of delivery traffic indication map (DTIM) information and the buffered data based on the assigned group information.
