D2D System of D2D communications and Method for resource and power allocation using the same

摘要

The present invention relates to a D2D communication systems and resources, and power allocation method using the same. According to a D2D communication systems and resources, and power allocation method using the same according to the present invention, in the D2D communication systems that share the cellular resources, the base station contained in the D2D communication system, a plurality of resources and a plurality of cellular terminals is occupied Share and among the block D2D performance of communication selected the best resource blocks by setting a shared resource block to be shared with the D2D terminal resource allocation unit, the corresponding D2D UE to share the monopoly of resource blocks that are occupied for D2D communication at least one to select another D2D unit-matching the exclusive resource allocation unit and the shared resource block and the exclusive resource blocks that are set to share with the appropriate D2D UE generates a resource block of the virtual and, included in the resource block of the virtual It includes the parts of the shared resource block and the power allocation to control the power allocated for the exclusive resource blocks. According to the invention, to improve the spectral efficiency of the system via a resource allocation for D2D cellular users share the resources with the resources exclusively assigned to the user in the D2D D2D system using the cellular resources. ;
