Method for coordination of resources between a next generation radio access network node and at least one further RAN node

A first radio access network (RAN) node according to a first Radio Access Technology (RAT), the first RAN comprising:

• a memory storing instructions;
• and
• a processor configured to process the instructions to:
• send, as part of a procedure for coordination of resources between the first RAN node and a second RAN node according to the first RAT or a second RAT, a message including a first information element for use in resource coordination between the first RAN node and the second RAN node,
• wherein the first information element includes a second information element that indicates resources intended to be used for transmission by the first RAN node, a cell identifier of the first RAN node, a cell identifier of the second RAN node, and a third information element for indicating whether the resource coordination is required.

A second radio access network (RAN) node according to a second Radio Access Technology (RAT) or a first RAT, the second RAN node comprising:

• a memory storing instructions;
• and
• a processor configured to process the instructions to:
• receive, as part of a procedure for coordination of resources between the second RAN node and a first RAN node according to the first RAT, a message including a first information element for use in resource coordination between the second RAN node and the first RAN node,
• wherein the first information element includes a second information element that indicates resources intended to be used for transmission by the first RAN node, a cell identifier of the first RAN node, a cell identifier of the second RAN node, and a third information element for indicating whether the resource coordination is required.
