1. A method for transmitting data by a station (STA) in a communication system, the method comprising:communicating with a first access point (AP) being present in a first basic service set (BSS) in which the STA is present;
identifying a condition;
receiving, from a second AP positioned adjacent to the STA, data of a second BSS associated with the second AP by using an idle antenna, base-band processing unit, and a modem in a case that the condition is satisfied, wherein the second BSS is different from the first BSS;
transmitting, to the first AP, the data of the second BSS associated with the second AP; and
receiving, from the first AP, mode information related to operation protocols and frequency bands of the first BSS managed by the first AP,
wherein the condition is set based on one of a noise strength estimated by the STA, a network load of the first BSS, and a probability of transmission failure of the STA, and
wherein the mode information is determined based on the data of the second BSS associated with the second AP.
