A data communication method in a basic service set (BSS) of a wireless communication system using a carrier sense multiple access with collision avoidance (CSMA/CA) protocol includes: performing, by first and second nodes within the BSS, communication within a predetermined first time period; and transmitting, by a third node within the BSS, data to a fourth node within the first time period through a channel which is not used by the other nodes.
