    Abstract: An electronic device, information processing apparatus, and information processing method. The electronic device at a base station side includes a processor circuit. The processor circuit is configured to acquire information related to a success rate of uplink transmission in an unlicensed frequency band of at least one user equipment unit, wherein the user equipment unit employs a channel detection process to perform carrier sensing on the unlicensed frequency band, and the channel detection process includes a random back-off process having a variable contention window size. The processor circuit is further configured to adjust, based on the information, the contention window size of the user equipment unit. The processor circuit is further configured to perform control, such that the user equipment unit is notified of the adjusted contention window size or a value of a random back-off counter generated on the basis of the adjusted contention window size.

    Abstract: A frequency spectrum management device includes a processing circuit and is configured so that: a first subsystem manages the frequency spectrum management device, an allocation coefficient between other subsystems and the first subsystem is determined on the basis of the distances from the first subsystem and the other subsystems to a main system, the allocation coefficient expresses the degree of interference of aggregated interference that the other subsystems and the first subsystem produce with respect to the main system; and a frequency spectrum resource is allocated to the first subsystem on the basis of the allocation coefficient. The use of the frequency spectrum management device, the electronic device, and the method executed thereby of the present disclosure increases the degree of rationality of frequency spectrum resource allocation for the subsystems.

    Abstract: An electronic apparatus and a method for a spectrum management device are provided. The electronic apparatus includes processing circuitry configured to: acquire, for a predetermined primary system, an interference radiation map representing interference amounts of secondary systems at locations in a management region of the spectrum management device to the primary system; and determine an exclusion zone for the primary system based on the interference radiation map, where secondary systems in the exclusion zone cannot use a spectrum which is being used by the primary system.
