Claim of US Patent No. 10,433,352

1. An operation method of a first communication node in a mobile xhaul network comprising a plurality of communication nodes each of which has mobility, the operation method comprising:performing a discovery procedure for a second communication node;
establishing a link with the second communication node discovered through the discovery procedure;
supporting an attach procedure between the second communication node and a third communication node performing network-wide resource management, wherein the third communication node assigns a unique ID to the second communication node through the attach procedure; and
changing an operation mode of the first communication node from an idle mode to a master mode after establishing the link,
wherein an operation mode of the second communication node is changed from an idle mode to a slave mode after establishing the link, a node in the master mode allocates resources to nodes in the slave mode for communications, and a node in the idle mode does not communicate with any other nodes, and
wherein a state of the second communication node is changed from a deregistered state into a registered state when the attach procedure between the second communication node and the third communication node is completed, and the state of the second communication node is changed from an unlinked state to a linked state after establishing the link.
