1. A method of forming a communication link by a device-to-device (D2D) user equipment (UE) in a wireless communication system, the method comprising:
measuring CBR (channel busy ratio)s for a plurality of beams configured for a D2D communication;
selecting a specific beam from among the plurality of beams based on the CBRs; and
performing the D2D communication with a communication device using the specific beam,
wherein transmission parameters for the D2D communication is determined based on the CBR measured for the specific beam.
