USER DEVICE, BASE STATION, METHOD FOR ADJUSTING DISCOVERY SIGNAL INTERVAL, AND METHOD FOR CONTROLLING USER DEVICE

摘要

A user apparatus configured to transmit and receive a discovery signal by using a discovery channel, for transmitting and receiving the discovery signal, at a discovery signal interval that is a predetermined time interval, including: resource utilization status obtaining means that obtains information indicating resource utilization status in the discovery channel; transmission means that transmits, to a base station, information indicating the resource utilization status obtained by the resource utilization status obtaining means; and adjustment means that receives, from the base station, a control signal including an indicator value corresponding to resource utilization status in the discovery channel, and that adjusts the discovery signal interval based on the indicator value included in the control signal.
