An apparatus and method are provided for transmitting data in a station of a wireless local area network (LAN) system. In the apparatus, a data queue stores transmission data, and a data processor processes data output from the data queue. A radio frequency (RF) module up-converts a signal output from the data processor to a frequency band of the wireless LAN system, and transmits the up-converted signal as an RF signal. A scheduler performs scheduling such that a specific stepping index decreases each time a backoff time reaches‘0’so as to determine whether to transmit the data, and the data is transmitted when both the stepping index and the backoff time reach‘0’. A backoff stepping generator determines an initial value of the stepping index within a predetermined range. |
