Communication technique setting method for device-to-device direct communication in wireless communication system, and device therefor

A method for transmitting a signal by a user equipment (UE) in a wireless communication, the method comprising:

• receiving information related to a first resource pool for a first type communication and information related to a second resource pool for a second type communication;
• transmitting a first signal in the first resource pool based on the first type communication, when a traffic of the first resource pool is less than a first threshold value;
• and
• transmitting the first signal in the first and the second resource pool based on the first type communication, when the traffic of the first resource pool is greater than or equal to the first threshold value.

A user equipment (UE) for transmitting a signal in a wireless communication, the UE comprising:

• a transceiver for transmitting and receiving the signal;
• and
• a processor for controlling the transceiver;
• wherein the processor is configured to:
• control the transceiver to receive information related to a first resource pool for a first type communication and information related to a second resource pool for a second type communication;
• control the transceiver to transmit a first signal in the first resource pool based on the first type communication, when a traffic of the first resource pool is less than a first threshold value;
• and
• control the transceiver to transmit the first signal in the first and the second resource pool based on the first type communication, when the traffic of the first resource pool is greater than or equal to the first threshold value.
