MOBILE COMMUNICATION SYSTEM, BASE STATION, USER TERMINAL AND PROCESSOR |
| 摘要 |
A mobile communication system according to the present invention supports D2D communication that is direct device-to-device communication in which a data path does not pass through a core network, The mobile communication system has a user terminal that exists on a cell managed by a base station and a plurality of user terminals that include the user terminal and perform a process of discovering a partner terminal in the D2D communication or the D2D communication, in which a maximum value of transmission power used by the user terminal for the discovering process or the D2D communication is calculated so that the maximum value becomes larger according to the number of the plurality of user terminals, and the user terminal performs the discovering process or the D2D communication so that the transmission power does not exceed the maximum value. |

1. A mobile communication system that supports D2D communication that is direct device-to-device communication in which a data path does not pass through a core network, comprising:
a user terminal that exists on a cell managed by a base station; and a plurality of user terminals that include the user terminal and that perform a process of discovering a partner terminal in the D2D communication or the D2D communication, wherein a maximum value of transmission power used by the user terminal for the discovering process or the D2D communication is calculated so that the maximum value becomes larger according to the number of the plurality of user terminals, and the user terminal performs the discovering process or the D2D communication so that the transmission power does not exceed the maximum value. |
