Abstract:
A user terminal and processor for controlling a user terminal having the function of device-to-device (D2D) discovery. In an aspect, a user terminal determines whether a user terminal is in a radio resource control (RRC) idle mode, receives a system information block (SIB) broadcasted by the base station in the RRC idle mode, and transmits a discovery signal to other user terminal by the D2D discovery based on the SIB. The SIB includes resource information indicating usable radio resources for transmitting the discovery signal and power information for controlling transmission power used in transmitting the discovery signal. In another aspect, the terminal stores preconfigured resource and power information used to control D2D discovery, determines whether the terminal is in out of coverage by not detecting at least one cell meeting a criterion, and determines to use the stored resource and power information in response to an out of coverage determination.

Claim (Index 3):
A user terminal having a function of D2D discovery for discovering proximal terminals, comprising:\n a storage configured to store both resource information and power information that are preconfigured, wherein the resource information and the power information are used to control the D2D discovery; a controller configured to determine whether the user terminal is in out of coverage, wherein the controller determines that the user terminal is in the out of coverage when the user terminal cannot detect at least one cell meeting a criterion based on a received power of radio signal, wherein the controller further determines to use the resource information and the power information stored in the storage when the user terminal is in the out of coverage; and a transmitter configured to transmit a discovery signal to other user terminals by the D2D discovery based on both the resource information and the power information when the user terminal exists in the out of coverage, wherein the resource information indicates usable radio resources for the D2D discovery, the power information is used for controlling transmission power in the D2D discovery, the controller is further configured to:\n determine radio resources used to transmit the data based on the resource information, and \n determine transmission power used in transmitting the discovery signal based on the power information, and \n the transmitter is further configured to transmit the discovery signal by using the determined radio resources and the determined transmission power.
