Method and apparatus for transmitting indication for d2d operation in wireless communication system

A wireless device in a wireless communication system, the wireless device comprising:

• a memory;
• a transceiver configured to transmit or receive a radio signal;
• and
• a processor, operably coupled to the memory and the transceiver,
• wherein the wireless device is configured to:
• receive, via the transceiver, broadcast signaling from a network, wherein the broadcast signaling informs that the network supports a device-to-device (D2D) related information;
• after receiving the broadcast signaling, transmit, via the transceiver, a message including the D2D related information based on a change of the D2D related information to the network;
• receive, via the transceiver, D2D radio resources from the network via a dedicated signaling;
• and
• perform, via the transceiver, a D2D operation based on the D2D radio resources.

A processor for a wireless device in a wireless communication system, wherein the processor is configured to:

• control the wireless device to receive broadcast signaling from a network, wherein the broadcast signaling informs that the network supports a device-to-device (D2D) related information;
• after receiving the broadcast signaling, control the wireless device to transmit a message including the D2D related information based on a change of the D2D related information to the network;
• control the wireless device to receive D2D radio resources from the network via a dedicated signaling;
• and
• control the wireless device to perform a D2D operation based on the D2D radio resources.
