METHOD AND APPARATUS FOR TRANSMITTING DATA IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method for transmitting data by a station (STA) device in a LAN (Wireless LAN) system. The method for transmitting data by an 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); obtaining an endurable interference margin (EIM) information and transmission power information of the first STA from the received signal; obtaining a predicted interference power (PIP) using the transmission power information of the first STA; and comparing the EIM with the PIP, and based on the comparison result, adjusting a CCA level or adjusting the transmission power.
