Abstract: Provided is a method for scanning an Access Point (AP) in a wireless communication system. The method includes receiving a beacon frame from a proximity AP located within a proximity of a User Equipment (UE) and determining whether a channel where the proximity AP is located is congested; if the channel is not congested, scanning at least one AP operating on the channel, and searching for a first AP that can communicate with a highest signal strength; determining whether to perform re-scanning for an AP in the channel; if it is determined to perform the re-scanning, predicting a time that a beacon frame is to be transmitted from the first AP; receiving a beacon frame from the first AP at the predicted time, and determining whether the channel where the first AP is located is congested; and if the channel is not congested, re-scanning at least one AP operating on the channel.
