Abstract: A method for measuring and reporting a D2D resource by a terminal that supports D2D communication according to an embodiment of the present invention comprises the steps of: measuring a resource usage rate of a first link that is being used by the terminal for D2D communication; transmitting a measurement report including the measured resource usage rate to a base station when the measured resource usage rate exceeds a first threshold value or less than a second threshold value; and receiving resource reallocation information for offloading the D2D communication, from the base station, wherein the resource reallocation information includes probability values indicating probabilities that the first link and the second link, which is configured in a resource different from that of the first link, will be used for the D2D communication, respectively. The terminal may offload the D2D communication performed in the first link onto the second link when the second link is selected through a link selection performed on the basis of the probability values.
