Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Link setup using different Radio Access Technologies (RATs) in a wireless communication system is provided. A method for operating a device supporting a first RAT and a second RAT includes sending information notifying a discovery interval start time for the second RAT, using the first RAT, and sending discovery signals during the discovery interval using the second RAT.

Abstract: In the wireless mesh network including a sender, a receiver, and a plurality of access points disposed between the sender and the receiver, available transmission paths between the sender and the receiver are determined; transmission expected values are calculated for the transmission paths; and a transmission path having a minimum transmission expected value is set as an actual transmission path. The transmission expected value is a sum of expected transmission counts, which is a reciprocal of multiplication of forward transmission success rate and backward transmission success rate of a communication link between the nodes disposed on the transmission paths. When an access point can transmit a packet concurrently with another access point, the expected transmitted count is reduced by half.

Abstract: Provided is an association control method for maximizing a message in message (MIM) function in a WLAN environment. According to an exemplary embodiment of the present invention, when all SINR values of transmission links to two or more first clients associated with the first access point are equal to or more than a predetermined capture threshold, SINR value of a transmission link to a second client associated with the second access point is less than the capture threshold, and at least one of the first clients, referred to as a third client group, can be associated with the second access point, associations are modified so that the third client group is associated with the second access point to enable concurrent transmission.

Abstract: Provided is an opportunistic concurrent transmission method for achieving efficient transmission with limited wireless resources in a WLAN environment. According to an exemplary embodiment of the present invention, when a packet to be transmitted is provided in an access point in a wireless network system, information on a link which is performing transmission from another access point is acquired by overhearing transmission from another access point, a signal to interference plus noise ratio (SINR) value of the link is verified by referring an interference map, and the packet is concurrently transmitted when the verified SINR value is equal to or more than a predetermined capture threshold.
