USER TERMINAL, WIRELESS BASE STATION, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed so that the increase of power consumption in D2D terminals is prevented even when a frequency carrier that does not have an expanded coverage is used as a D2D signal transmitting/receiving resource where D2D operations are executed in a network in which multiple frequencies are in use. A user terminal is capable of transmitting and receiving device-to-device signals, and has a receiving section that receives system information, which is transmitted from the connecting or serving radio base station and which contains at least information about the resources for transmitting and receiving the device-to-device signals, and a control section that, based on the information about the device-to-device signal transmitting/receiving resources, executes control so that the device-to-device signals are transmitted and received in a second frequency carrier, which is different from a first frequency carrier, in which the information about the device-to-device signal transmitting/receiving resources is transmitted.
