BASE STATION AND COMMUNICATION CONTROL METHOD
First Claim
1. A base station configured to be used in a mobile communication system that supports cellular communication in which a data path passes through a core network, and D2D communication that is direct device-to-device communication in which a data path does not pass through the core network, comprising:
- a controller configured to assign a dedicated radio resource not shared with the D2D communication or a shared radio resource shared with the D2D communication to each of a plurality of cellular terminals that performs the cellular communication, whereinthe controller comprises;
a scheduler configured to select a cellular terminal, to which the shared radio resource is assigned, from the plurality of cellular terminals according to assignment priority of the shared radio resource, andthe scheduler calculates the assignment priority for each of the plurality of cellular terminals such that influence of interference between the cellular communication and the D2D communication is alleviated.

Abstract
A base station configured to be used in a mobile communication system that supports cellular communication in which a data path passes through a core network, and D2D communication that is direct device-to-device communication in which a data path does not pass through the core network, comprises: a control unit configured to assign a dedicated radio resource not shared with the D2D communication or a shared radio resource shared with the D2D communication to each of a plurality of cellular terminals that perform the cellular communication. The control unit comprises: a scheduler configured to select a cellular terminal, to which the shared radio resource is assigned, from the plurality of cellular terminals according to assignment priority of the shared radio resource. The scheduler calculates the assignment priority for each of the plurality of cellular terminals such that influence of interference between the cellular communication and the D2D communication is alleviated.

12. A communication control method that is used in a mobile communication system that supports cellular communication in which a data path passes through a core network, and D2D communication that is direct device-to-device communication in which a data path does not pass through the core network, comprising:
-
selecting, by a base station, a cellular terminal, to which a shared radio resource is assigned, from a plurality of cellular terminals that perform the cellular communication, according to assignment priority of the shared radio resource, the base station assigning a dedicated radio resource not shared with the D2D communication or the shared radio resource shared with the D2D communication to each of the plurality of cellular terminals, wherein the base station calculates the assignment priority for each of the plurality of cellular terminals such that influence of interference between the cellular communication and the D2D communication is alleviated.
