GROUPING-BASED DATA TRANSCEIVING METHOD IN WIRELESS LAN SYSTEM AND APPARATUS FOR SUPPORTING SAME

摘要

Provided is a data transceiving method performed by a station (STA) in a wireless LAN system. The method comprises: receiving sub-grouping parameter information from an access point (AP); determining whether a frame buffered in the STA sub-group in which the STA is contained exists or not based on the sub-grouping parameter information; receiving a TIM element in a channel access interval for the STA sub-group from the AP if the buffered frame exists; and exchanging the AP and the frame in the channel access interval based on the TIM element.
