1. An electronic apparatus for wireless communications, comprising:
processing circuitry, configured to:
determine a first resource utilization system and a second resource utilization system within a management range of a spectrum management device, which have coverage overlap with each other and adopt the same radio access technology or adopt different radio access technologies respectively; and
determine, based on interference conditions between the first resource utilization system and the second resource utilization system, spectrum resources allocated to the first resource utilization system and those allocated to the second resource utilization system,
wherein the processing circuitry is further configured to determine the first resource utilization system and the second resource utilization system using an interference overlapping map,
wherein in the interference overlapping map, an edge is connected between a first vertex representing the first resource utilization system and a second vertex representing the second resource utilization system, and
wherein the interference overlapping map is created using information provided by the first and second resource utilization systems,
wherein the processing circuitry is configured to determine the width of the guard band based on a measurement result of interference measuring performed by a terminal device located in an overlapping region of the first resource utilization system and the second resource utilization system,
wherein the measurement result comprises one or more of the following: co-channel interferences, adjacent channel interferences, a co-channel interferences-to-noise ratio, an adjacent channel interferences-to-noise ratio, an out of band emission model of the first resource utilization system and/or the second resource utilization system, and
wherein:
the terminal device is a terminal device served by the first resource utilization system;
the measurement result comprises a co-channel interferences-to-noise ratio and an adjacent-channel interferences-to-noise ratio of the terminal device, and an out of band emission model of the second resource utilization system; and
the processing circuitry is configured to:
calculate a difference between the co-channel interferences-to-noise ratio and a co-channel interferences-to-noise ratio threshold and a difference between the adjacent-channel interferences-to-noise ratio and an adjacent-channel interferences-to-noise ratio threshold, as an interference margin; and
determine the width of the guard band based on the interference margin and the out of band emission model.
