How a base station in a wireless communication system D2D (Device-to-Device) method to support communication and D2D terminal transmits efficiently the D2D communication request signal

摘要

Method of the base station according to the present invention supports D2D (Device-to-Device) communication includes receiving a first signal requesting the D2D communication from the first plurality of D2D terminals , based on the first signal the and to grasp the number of D2D terminals requesting the D2D communication , based on the number of the first plurality of D2D terminals that are the grasp resources for transmitting a second signal requesting a D2D communication between D2D terminal wherein the assigning , and the information about the allocated resources , and sending the first plurality of D2D terminal which transmits the first signal , wherein the resource allocation , which transmitted the first signal the first plurality of terminals D2D , the second signal time for a combination of the index of the D2D terminal receiving the index and the second signal of the D2D terminal that transmits the frequency , at least the code and the spatial domain in can be assigned so as to be distinguished by one .
