1. A method for performing communication by a device-to-device (D2D) user equipment (UE) performing D2D communication in a wireless communication system supporting the D2D communication, the method comprising:

  • receiving transmission request signals from other D2D UEs;

    detecting a transmission request signal for the D2D UE from at least one first D2D UE among the other D2D UEs;

    when the transmission request signal from the at least one first D2D UE is detected, measuring a received signal power or a signal-to-noise ratio (SNR) of the received transmission request signals;

    generating, based on the measurement, D2D link information including at least one of received signal power or SNR information about a D2D link between the D2D UE and the at least one first D2D UE and interference information about an interference level caused by the at least one second D2D UE among the other D2D UEs, wherein the interference information includes at least one identifier of the at least one second D2D UE;

    transmitting a bandwidth request for D2D communication and information about a Physical Uplink Shared Channel (PUSCH) including the generated D2D link information to a base station through a Physical Uplink Control Channel (PUCCH); and

    transmitting the generated D2D link information to the base station through the PUSCH.
