Method for performing device-to-device communication in wireless communication system and apparatus therefor

A first UE performing (D2D) communication in a wireless communication system, comprising:

• a radio frequency (RF) unit for transmitting and receiving a radio signal;
• and
• a processor functionally connected to the RF unit,
• wherein the processor is configured:
• to transmit, to a first eNB, transmission/reception (TX/RX) chain number information indicating the number of supported TX/RV radio frequency (RF) chains;
• to receive, from the first eNB, a first control message including D2D resource pool configuration information of the first eNB;
• to receive, from the first eNB, a second control message including D2D resource pool configuration information of a second eNB;
• and
• to transmit a first D2D signal to the first eNB and/or transmit a second D2D signal to the second eNB using one or more TX RF chains when a predetermined condition is satisfied.
