Method and apparatus for interference-aware resource-sharing scheme for multiple D2D group communications underlaying cellular networks

摘要

A method and apparatus for an interference-aware resource-sharing scheme for multiple D2D group communications is provided. The method for interference-aware resource-sharing scheme for multiple D2D communications includes initializing a D2D communication request and deciding the numbers of D2D pairs and CUEs, grouping D2D pairs according to the decided numbers of the D2D pairs and CUEs, selecting target CUEs for the grouped D2D pairs to share frequency resources, applying interference alignment to the D2D groups, updating the set of the CUEs and D2D pairs, and moving the rest of the D2D pairs to the orthogonal group.
