RESOURCE ALLOCATION METHOD FOR D2D COMMUNICATION IN A CELLULAR MOBILE TELECOMMUNICATION SYSTEM WHICH CAN EFFICIENTLY ASSIGN RESOURCES FOR A D2D LINK

摘要

PURPOSE: A resource allocation method for D2D (device to device) communication in a cellular mobile telecommunication system can perform flexible and effective resource allocation having small down link control channel using capacity of a base station.;CONSTITUTION: Operation information including information of at least one resource allocation pattern available for a D2D communication link is provided to terminals performing D2D communication for each terminal and D2D communication link (S410). A buffer status report is received from a terminal performing the D2D communication (S420). An indicating value indicating at least one of resource allocation patterns with reference to the buffer state report is transmitted (S430). Cellular link communication between the terminals is performed by using resource allocated to a cellular link by a resource allocation pattern indicated by the indicating value.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S410) Step of providing operation information including information of resource allocation pattern to terminals; (S420) Step of receiving a buffer status report from a terminal; (S430) Step of transmitting an indicating value indicating at least one of resource allocation patterns with reference to the buffer state report
