Method for operating terminal in wireless communication system, and terminal using said method
Provided is a method for operating a terminal in a wireless communication system and a terminal using said method. The method comprises the steps of: transmitting, to a network, information indicating transmission necessity of a terminal-to-terminal control message; receiving, from the network, a setting regarding transmission of the terminal-to-terminal control message; and transmitting, to another terminal, the terminal-to-terminal control message on the basis of the setting.
1. A method for transmitting a resource pool announcement in a wireless communication system, the method performed by a first user equipment (UE) and comprising:
transmitting, to a network, resource pool announcement necessity information;
receiving from the network, a configuration for the resource pool announcement in response to the resource pool announcement necessity information; and
transmitting, to a second UE, the resource pool announcement based on the configuration,
wherein the resource pool announcement necessity information informs the network that the first UE, which is in a network coverage, must transmit the resource pool announcement to the second UE which is out of the network coverage, and
wherein the resource pool announcement indicates at least one of a plurality of resources which is used for transmitting a device-to-device (D2D) signal in the network coverage.
2. The method of claim 1 , wherein the resource pool announcement further indicates the second UE of information required to perform a relay function by the first UE between the second UE and the network.
3. The method of claim 1 , wherein the resource pool announcement necessity information is transmitted via a radio resource control (RRC) message.
4. The method of claim 1 , wherein the resource pool announcement is a control message to be used for public safety.
5. The method of claim 1 , further comprising:
transmitting to the network, information indicating that the resource pool announcement is no longer required.
6. A user equipment (UE), the UE comprising:
a transceiver; and
a processor, operatively coupled to the transceiver, wherein the processor is configured to:
control the transceiver to transmit, to a network, resource pool announcement necessity information;
control the transceiver to receive from the network, a configuration for the resource pool announcement in response to the resource pool announcement necessity information; and
control the transceiver to transmit, to a second UE, a resource pool announcement based on the configuration,
wherein the resource pool announcement necessity information informs the network that the first UE, which is in a network coverage, must transmit the resource pool announcement to the second UE which is out of the network coverage, and
wherein the resource pool announcement indicates at least one of a plurality of resources which is used for transmitting a device-to-device (D2D) signal in the network coverage.
7. The UE of claim 6 , wherein the resource pool announcement further indicates the second UE of information required to perform a relay function by the first UE between the second UE and the network.
8. The UE of claim 6 , wherein the resource pool announcement necessity information is transmitted via a radio resource control (RRC) message.
9. The UE of claim 6 , wherein the resource pool announcement is a control message to be used for public safety.
10. The UE of claim 6 , wherein the UE further transmits to the network, information indicating that the resource pool announcement is no longer required.
