METHOD AND DEVICE FOR TRANSMITTING DATA IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method by which a station (STA) device transmits data in a wireless LAN (LAN) system. The method for transmitting the data of the STA device, according to the present invention, comprises the steps of: receiving a signal from a first STA of a first basic service set (BSS); acquiring endurable interference margin (EIM) information and transmission power information of the first STA from the received signal; acquiring predicted interference power (PIP) by using the transmission power information of the first STA; and comparing the EIM with the PIP, and adjusting a CCA level or the transmission power according to the compared result.
