Provided are a method and an apparatus for transmitting a buffer state report in a wireless communication system supporting device to device (D2D) communication. A method by which a user equipment transmits a buffer state report in a wireless communication system supporting D2D communication comprises the steps of: mapping a target ID, which is identification information on a subject on which the D2D communication is to be performed, to a logical channel group; transmitting, to a base station, information on a mapping relation between the target ID and an ID of the logical channel group by using a user equipment (UE) assistance information message; and transmitting, to the base station, a buffer state report on D2D data to be transmitted to the subject. |
