Abstract:
The present invention relates to a method and apparatus for performing communication using wi-fi between devices. The method includes: scanning channels that are available to gather information related to surroundings: transmitting a probe request frame through a social channel for searching devices that are to perform communication; receiving a probe response frame from the second device through a listen channel in response to the probe request frame in a listen state; and performing a group owner negotiation with the second device in order to determine a group owner, wherein the listen channel is included in the social channel, and wherein the probe request frame is transmitted from each social channel, and a predetermined hold time is present for receiving the probe response frame after transmitting the probe request frame in each social channel.
