    摘要： 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.

    摘要： In a wireless communication system formed of a plurality of nodes, an arbitrary node receives messages broadcasted from neighbor nodes and calculates amounts of changes in receiving times that are differences between receiving times when the messages are currently received and receiving times when the messages are previously received with respect to the neighbor nodes. The node corrects reference time thereof based on the amounts of changes calculated with respect to the neighbor nodes.

    摘要： A transmit node receives a transformed correlation matrix or a correlation matrix of a channel coefficient matrix, or a correlation matrix of an interference channel coefficient matrix from each of receive nodes sharing a radio resource. The transmit node determines a precoder based on a value maximizing values determined by the transformed correlation matrix or the correlation matrix of the channel coefficient matrix, or a value minimizing values determined by the correlation matrix of the interference channel coefficient matrix, and precodes a transmit signal by using the determined precoder.

    摘要： 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.
