Resource management method, control information transmission method and information configuration method

A resource management method performed by a second node in a wireless communication system, the method comprising:

• receiving, from a first node, a first backhaul link resource management request including a first resource configuration request, wherein the first backhaul link resource management request includes first information on backhaul link resources referred by the first backhaul link resource management request;
• transmitting, to the first node, a second backhaul link resource management request including a first resource configuration modification request in response to the first resource configuration request, wherein the second backhaul link resource management request includes second information on backhaul link resources;
• receiving, from the first node, a first resource configuration modification request response;
• and
• transmitting, to the first node, a first request response message based on the first resource configuration request and the first resource configuration modification request response.

A first node in a wireless communication system, the first node comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller coupled with the transceiver and configured to:
• transmit, to a second node, a first backhaul link resource management request including a first resource configuration request, wherein the first backhaul link resource management request includes first information on backhaul link resources,
• receive, from the second node, a second backhaul link resource management request including a first resource configuration modification request in response to the first resource configuration request, wherein the second backhaul link resource management request includes second information on backhaul link resources,
• transmit, to the second node, a first resource configuration modification request response, and
• receive, from the second node, a first request response message based on the first resource configuration request and the first resource configuration modification request response.
