Abstract
[Object] To make it possible to prevent a load from being concentrated on a specific node when a frequency band is shared between the cellular system employing the HetNet and other systems. [Solution] Provided is an apparatus, including: an acquiring unit configured to acquire band-related information that is related to a frequency band available to a macro cell base station of a cellular system among shared bands shared between the cellular system and another system and is provided from a controller for a plurality of macro cell base stations of the cellular system; and a control unit configured to decide a frequency band available to a small cell base station corresponding to the macro cell base station among the frequency bands available to the macro cell base station.
Claims20
An apparatus for managing a plurality of frequency bands that are shared between a cellular system and another system, the apparatus comprising:
- circuitry configured to:
- acquire, from a controller, band related information that indicates information relating to frequency bands usable by the cellular system;
- determine a frequency band that is usable by a small cell base station belonging to the cellular system;
- and
- notify the small cell base station of the frequency band that is usable by the small cell base station.
A terminal device for performing wireless communication with a base station of a cellular system using a frequency band, usable by the cellular system, among a plurality of frequency bands shared between the cellular system and another system, the terminal device comprising:
- circuitry configured to use a transmission power and/or a period of the frequency band, the frequency band having been set by the base station as a secondary component carrier (SCC) of carrier aggregation.
The terminal device according to claim 18, wherein the transmission power is a maximum transmission power based on a communication quality of the base station.
