Wireless communication method and wireless communication device for managing interference between multiple devices

A method of managing, by a first device including one or more processors, a plurality of systems interfering with a reference point, the method comprising:

• determining, among the plurality of systems, a group of systems which are managed by a second device based on information related to the plurality of systems;
• determining a total amount of interference which the group of systems are allowed to generate at the reference point, based on an interference limit allowable at the reference point;
• and
• informing the second device of the determined total amount of interference, such that the second device is able to determine a communication resource for each of the group of systems based on the total amount of interference,
• wherein the second device comprises a plurality of second devices, and the method further comprises:
• determining, among the plurality of systems, a plurality of groups of systems respectively managed by the plurality of second devices, based on the information related to the plurality of systems;
• determining a distribution area for each group of systems based on position information of respective systems in each group of systems;
• and
• determining an overlapping area among a plurality of distribution areas of the plurality of groups of systems based on vertex positions of the plurality of distribution areas.
