Claim:
1. A method for obtaining, by a node of a primary radio access technology (RAT) system, information related to a beacon transmission in a wireless communication system, the method comprising: obtaining first information related to the beacon transmission, the first information including information on a frequency channel, a beacon interval and a start point of the beacon interval of each entity of a secondary RAT system; and transmitting second information related to the beacon transmission based on the obtained first information to a user equipment through the primary RAT system, wherein the start point of the beacon interval of each entity of the secondary RAT is aligned by being synchronized with a start point of a subframe of the primary RAT system, wherein the second information related to the beacon transmission includes the start point of the beacon interval of each entity of the secondary RAT system, wherein the start point of the beacon interval of each entity of the secondary RAT system included in the second information related to the beacon transmission is set as a time point in the nearest future at which the user equipment can receive a beacon, based on the start point of the beacon interval of each entity of the secondary RAT system obtained via the first information related to the beacon transmission, wherein the primary RAT is a 3rd generation partnership project (3GPP) long-term evolution (LTE) system, and wherein the secondary RAT system is a Wi-Fi system.
