Abstract: Disclosed is an authentication method of a wireless mesh network capable of reducing overload and communication delay during authentication procedure by performing authentication between nodes without accessing an authentication server. The authentication method of a wireless mesh network according to an exemplary embodiment of the present disclosure includes: selecting, by a new node, a first neighbor node among one or more adjacent nodes; transmitting, by the new node, an authentication request message including a public key of the new node; authenticating, by the first neighbor node, the public key of the new node; transmitting, by the first neighbor node, an authentication response message including a public key of the first neighbor node to the new node; and authenticating, by the new node, the public key of the first neighbor node; transmitting, by the new node, an authentication identification message to the first neighbor node.

Abstract: Disclosed herein are a method of beamforming and a 3D antenna array. The method includes: transmitting a first control channel; receiving first feedback information on a first antenna set and a first precoding scheme of a plurality of antenna sets included in the 3D antenna array, which are determined based on the first control channel, from a first communication node different from the communication node; and beamforming a traffic channel to be transmitted to the first communication node using the first antenna set and the first precoding scheme.

Abstract: If a target node that enters into a transmission range is sensed, a mesh node of a wireless communication system selects an agent node having itself and a target node as a neighboring node among a plurality of neighboring nodes to form a link with the target node through the agent node. Also, the mesh node deletes the formed link if a target node that is out of a transmission range among a plurality of neighboring nodes is sensed, and forms a substitution path for at least a portion among an entire path of a connection including the deleted link.

Abstract: A communication method for a third device that controls a first link established directly between a first device and a second device is provided. The third device allocates a first link identifier for identifying the first link. The third device transmits first information including the first link identifier to the first device and the second device. The third device receives, from the first device and the second device, second information including allocation acceptance information indicating the acceptance or rejection of allocation of the first link identifier.

Abstract: A multimode apparatus and a communication method thereof are disclosed. If the multimode apparatus is chosen to serve as a relay station due to a base station having a backhaul link problem, it sets up a first relay link with a first base station. Upon receiving a request for releasing the first relay link from the first base station even though the backhaul link is not restored, the multimode apparatus sets up a second relay link with a second base station, or configures and operates a standalone network or an independent network.

Abstract: A communication method of a terminal that can operate in a relay mode or a base station mode is provided. When the terminal, having received a service from a first base station, detects that a service connection to the first base station is unavailable, the terminal searches for a second base station, which is an available neighboring base station. The terminal transmits a ranging request message including a base station identifier of the first base station to the second base station.
