Abstract: Provided are an electronic device and method for wireless communication, and a computer-readable storage medium. The electronic device comprises: a processing circuit, configured to: construct an interference overlapping diagram based on an interference/coexistence relationship between resource application systems within a management range, wherein a connection point of the interference overlapping diagram represents one or more resource application systems, and an edge of the interference overlapping diagram represents the fact that interference exists between the resource application systems represented by two connection points linked with the edge; remove one or more edges in the interference overlapping diagram so as to enable the interference overlapping diagram to meet a pre-determined condition after the removal; and carry out channel/resource allocation based on the adjusted interference overlapping diagram.
