METHOD FOR TRANSMITTING AND RECEIVING DATA IN WIRELESS LAN SYSTEM SUPPORTING DOWNLINK FRAME TRANSMISSION INTERVAL AND DEVICE FOR SAME

摘要

The present document relates to a wireless communication system and, more particularly, to a data transmission and reception operation between an AP and an STA in a high density wireless LAN system. To this end, the STA receives a beacon frame including downlink frame transmission interval information from the AP, and receives data from the AP through a time interval corresponding to the downlink frame transmission interval information, wherein the data reception from the AP through the time interval corresponding to the downlink frame transmission interval information is processed at a higher priority than the data transmission toward the AP.
