D2D Resource Allocation Method for Multiple Device-to-Device Cluster Multicast Communications Underlay Cellular Networks and Apparatus thereof

摘要

A resource allocation method and apparatus for multi-D2D cluster multicast communication are disclosed. A method for allocating resources for multiple D2D cluster multicast communication according to an embodiment of the present invention is a method for allocating at least one cellular terminal and at least one D2D cluster in a cell covered by one base station, A method for allocating resources to D2D clusters in a system in which a transmitting terminal and a plurality of receiving terminals are located, the method comprising the steps of: acquiring location information of a cellular terminal and a transmitting terminal located in a cell, Calculating an outage probability of a corresponding D2D cluster using the calculated transmission power, calculating a transmission power of a transmitting terminal by using a predetermined out-of-cell probability and an outage probability, The sum of throughputs of all D2D clusters is calculated using the calculated outage probability And allocating a channel to be maximized.
