A method of performing paging by a first D2D terminal in a wireless communication system supporting D2D communication includes: obtaining information on a paging slot, the paging slot being designated to be dedicated to the first D2D terminal for the D2D communication and including a plurality of paging sections; monitoring whether a signal for the first D2D terminal is transmitted in a first paging section in the obtained paging slot through a region assigned to the first D2D terminal; monitoring whether a paging request message is transmitted in a paging region only for the first D2D terminal in a second paging section if the signal is detected; and transmitting a paging response message through a third paging section to the second D2D terminal that transmits the paging request signal, as a response to the paging request message, if the paging request message is detected.
